CLASSIFICATION OF MLS POINT CLOUDS IN URBAN SCENES USING DETRENDED GEOMETRIC FEATURES FROM SUPERVOXEL-BASED LOCAL CONTEXTS
Authors: Sun Z. , Xu Y. , Hoegner L. , Stilla U.
Published: May 2018

Abstract. In this work, we propose a classification method designed for the labeling of MLS point clouds, with detrended geometric features extracted from the points of the supervoxel-based local context. To achieve the analysis of complex 3D urban scenes, acquired points of the scene should be tagged with individual labels of different classes. Thus, assigning a unique label to the points of an object that belong to the same category plays an essential role in the entire 3D scene analysis workflow. Although plenty of studies in this field have been reported, this work is still a challenging task. Specifically, in this work: 1) A novel geometric feature extraction method, detrending the redundant and in-salient information in the local context, is proposed, which is proved to be effective for extracting local geometric features from the 3D scene. 2) Instead of using individual point as basic element, the supervoxel-based local context is designed to encapsulate geometric characteristics of points, providing a flexible and robust solution for feature extraction. 3) Experiments using complex urban scene with manually labeled ground truth are conducted, and the performance of proposed method with respect to different methods is analyzed. With the testing dataset, we have obtained a result of 0.92 for overall accuracy for assigning eight semantic classes.

Published: May 2018

Abstract. Monitoring and analyzing the (decreasing) trends in lake freezing provides important information for climate research. Multi-temporal satellite images are a natural data source to survey ice on lakes. In this paper, we describe a method for lake ice monitoring, which uses low spatial resolution (250 m–1000 m) satellite images to determine whether a lake is frozen or not. We report results on four selected lakes in Switzerland: Sihl, Sils, Silvaplana and St. Moritz. These lakes have different properties regarding area, altitude, surrounding topography and freezing frequency, describing cases of medium to high difficulty. Digitized Open Street Map (OSM) lake outlines are back-projected on to the image space after generalization. As a pre-processing step, the absolute geolocation error of the lake outlines is corrected by matching the projected outlines to the images. We define the lake ice detection as a two-class (frozen, non-frozen) semantic segmentation problem. Several spectral channels of the multi-spectral satellite data are used, both reflective and emissive (thermal). Only the cloud-free (clean) pixels which lie completely inside the lake are analyzed. The most useful channels to solve the problem are selected with xgboost and visual analysis of histograms of reference data, while the classification is done with non-linear support vector machine (SVM). We show experimentally that this straight-forward approach works well with both MODIS and VIIRS satellite imagery. Moreover, we show that the algorithm produces consistent results when tested on data from multiple winters.
STRUCTURED-LIGHT BASED 3D LASER SCANNING OF SEMI-SUBMERGED STRUCTURES

Published: May 2018

Abstract. In this work we look at 3D acquisition of semi-submerged structures with a triangulation based underwater laser scanning system. The motivation is that we want to simultaneously capture data above and below water to create a consistent model without any gaps. The employed structured light scanner consist of a machine vision camera and a green line laser. In order to reconstruct precise surface models of the object it is necessary to model and correct for the refraction of the laser line and camera rays at the water-air boundary. We derive a geometric model for the refraction at the air-water interface and propose a method for correcting the scans. Furthermore, we show how the water surface is directly estimated from sensor data. The approach is verified using scans captured with an industrial manipulator to achieve reproducible scanner trajectories with different incident angles. We show that the proposed method is effective for refractive correction and that it can be applied directly to the raw sensor data without requiring any external markers or targets.
FILTERING PHOTOGRAMMETRIC POINT CLOUDS USING STANDARD LIDAR FILTERS TOWARDS DTM GENERATION
Authors: Zhang Z. , Gerke M. , Vosselman G. , Yang M. Y.
Published: May 2018

Abstract. Digital Terrain Models (DTMs) can be generated from point clouds acquired by laser scanning or photogrammetric dense matching. During the last two decades, much effort has been paid to developing robust filtering algorithms for the airborne laser scanning (ALS) data. With the point cloud quality from dense image matching (DIM) getting better and better, the research question that arises is whether those standard Lidar filters can be used to filter photogrammetric point clouds as well. Experiments are implemented to filter two dense matching point clouds with different noise levels. Results show that the standard Lidar filter is robust to random noise. However, artefacts and blunders in the DIM points often appear due to low contrast or poor texture in the images. Filtering will be erroneous in these locations. Filtering the DIM points pre-processed by a ranking filter will bring higher Type II error (i.e. non-ground points actually labelled as ground points) but much lower Type I error (i.e. bare ground points labelled as non-ground points). Finally, the potential DTM accuracy that can be achieved by DIM points is evaluated. Two DIM point clouds derived by Pix4Dmapper and SURE are compared. On grassland dense matching generates points higher than the true terrain surface, which will result in incorrectly elevated DTMs. The application of the ranking filter leads to a reduced bias in the DTM height, but a slightly increased noise level.
RESIDUAL SHUFFLING CONVOLUTIONAL NEURAL NETWORKS FOR DEEP SEMANTIC IMAGE SEGMENTATION USING MULTI-MODAL DATA

Published: May 2018

Abstract. In this paper, we address the deep semantic segmentation of aerial imagery based on multi-modal data. Given multi-modal data composed of true orthophotos and the corresponding Digital Surface Models (DSMs), we extract a variety of hand-crafted radiometric and geometric features which are provided separately and in different combinations as input to a modern deep learning framework. The latter is represented by a Residual Shuffling Convolutional Neural Network (RSCNN) combining the characteristics of a Residual Network with the advantages of atrous convolution and a shuffling operator to achieve a dense semantic labeling. Via performance evaluation on a benchmark dataset, we analyze the value of different feature sets for the semantic segmentation task. The derived results reveal that the use of radiometric features yields better classification results than the use of geometric features for the considered dataset. Furthermore, the consideration of data on both modalities leads to an improvement of the classification results. However, the derived results also indicate that the use of all defined features is less favorable than the use of selected features. Consequently, data representations derived via feature extraction and feature selection techniques still provide a gain if used as the basis for deep semantic segmentation.
SATELLITE IMAGE CLASSIFICATION OF BUILDING DAMAGES USING AIRBORNE AND SATELLITE IMAGE SAMPLES IN A DEEP LEARNING APPROACH
Authors: Duarte D. , Nex F. , Kerle N. , Vosselman G.
Published: May 2018

Abstract. The localization and detailed assessment of damaged buildings after a disastrous event is of utmost importance to guide response operations, recovery tasks or for insurance purposes. Several remote sensing platforms and sensors are currently used for the manual detection of building damages. However, there is an overall interest in the use of automated methods to perform this task, regardless of the used platform. Owing to its synoptic coverage and predictable availability, satellite imagery is currently used as input for the identification of building damages by the International Charter, as well as the Copernicus Emergency Management Service for the production of damage grading and reference maps. Recently proposed methods to perform image classification of building damages rely on convolutional neural networks (CNN). These are usually trained with only satellite image samples in a binary classification problem, however the number of samples derived from these images is often limited, affecting the quality of the classification results. The use of up/down-sampling image samples during the training of a CNN, has demonstrated to improve several image recognition tasks in remote sensing. However, it is currently unclear if this multi resolution information can also be captured from images with different spatial resolutions like satellite and airborne imagery (from both manned and unmanned platforms). In this paper, a CNN framework using residual connections and dilated convolutions is used considering both manned and unmanned aerial image samples to perform the satellite image classification of building damages. Three network configurations, trained with multi-resolution image samples are compared against two benchmark networks where only satellite image samples are used. Combining feature maps generated from airborne and satellite image samples, and refining these using only the satellite image samples, improved nearly 4 % the overall satellite image classification of building damages.
Development of a methodological framework for the assessment of seismic induced tsunami hazard through uncertainty quantification: application to the
Azores-Gibraltar Fracture Zone

Published: May 2018

Abstract. The aim of this study is to show how a numerical database constructed using uncertainty quantification techniques can be a useful tool for the analysis of the tsunamigenic potential of a seismic zone. This methodology mainly relies on the construction and validation of some emulators, or meta-models, used instead of the original models in order to evaluate and quantify the uncertainty and the sensitivity of the tsunamis height at a given location to the seismic source parameters. The proposed approach was tested by building a numerical database of nearly 50 000 tsunamis scenarios generated by the Azores-Gibraltar Fracture Zone (AGFZ) and potentially impacting the French Atlantic Coast. This seismic area was chosen as test-case because of its complexity and the large uncertainty related to its characterization of tsunamigenic earthquake sources. Finally, the tsunami hazard resulting from uncertainty quantification was presented and discussed with respect to the results which can be obtained with a more classical deterministic (or scenario-based) approach. It must be underlined that the results from this study are the illustration of a general methodology through a case study with simplified hypothesis, which is not an operational assessment of tsunami hazard along the French Atlantic Coast.
Does the East Greenland Current exist in northern Fram Strait?
Authors: Richter Maren Elisabeth , von Appen Wilken-Jon , Wekerle Claudia
Published: May 2018

Abstract. Warm Atlantic Water (AW) flows around the Nordic Seas in a cyclonic boundary current loop. Some AW enters the Arctic Ocean where it is transformed to Arctic Atlantic Water (AAW) before exiting through Fram Strait. There the AAW is joined by recirculating AW. Here we present the first summer synoptic study targeted at resolving this confluence in Fram Strait which forms the East Greenland Current (EGC). Absolute geostrophic velocities and hydrography from observations in 2016, including four sections crossing the east Greenland shelfbreak, are compared to output from an eddy-resolving configuration of the sea–ice ocean model FESOM. Far offshore (120 km at 80.8° N) AW warmer than 2 °C is found in northern Fram Strait. The Arctic Ocean outflow there is broad and barotropic, but gets narrower and more baroclinic toward the south as recirculating AW increases the cross-shelfbreak density gradient. This barotropic to baroclinic transition appears to form the well-known EGC boundary current flowing along the shelfbreak further south where it has been previously described. In this realization, between 80.2° N and 76.5° N, the southward transport along the east Greenland shelfbreak increases from roughly 1 Sv to about 4 Sv and the warm water composition, defined as the fraction of AW of the sum of AW and AAW (AW/(AW + AAW)), changes from 19 ± 8 % to 80 ± 3 %. Consequently, in southern Fram Strait, AW can propagate into Norske Trough on the east Greenland shelf and reach the large marine terminating glaciers there. High instantaneous variability observed in both the synoptic data and the model output is attributed to eddies, the representation of which is crucial as they mediate the westward transport of AW in the recirculation and thus structure the confluence forming the EGC.
Impacts of a lengthening open water season on Alaskan coastal communities: deriving locally relevant indices from large-scale datasets and community observations
Authors: Rolph Rebecca J. , Mahoney Andrew R. , Walsh John , Loring Philip A.
Published: May 2018

Abstract. Using thresholds of physical climate variables developed from community observations, together with two large-scale datasets, we have produced local indices directly relevant to the impacts of a reduced sea ice cover on Alaska coastal communities. The indices include the number of false freeze-ups defined by transient exceedances of ice concentration prior to a corresponding exceedance that persists, false break-ups, timing of freeze-up and break-up, length of the open water duration, number of days when the winds preclude hunting via boat (wind speed threshold exceedances), the number of wind events conducive to geomorphological work or damage to infrastructure from ocean waves, and the number of these wind events with on- and along-shore components promoting water setup along the coastline. We demonstrate how community observations can inform use of large-scale datasets to derive these locally relevant indices. The two primary large-scale datasets are the Historical Sea Ice Atlas for Alaska and the atmospheric output from a regional climate model used to downscale the ERA-Interim atmospheric reanalysis. We illustrate the variability and trends of these indices by application to the rural Alaska communities of Kotzebue, Shishmaref, and Utqiaġvik (previously Barrow), although the same procedure and metrics can be applied to other coastal communities. Over the 1979–2014 time period, there has been a marked increase in the number of combined false freeze-ups and false break-ups as well as the number of days too windy for hunting via boat for all three communities, especially Utqiaġvik. At Utqiaġvik, there has been an approximate tripling of the number of wind events conducive to coastline erosion from 1979 to 2014. We have also found a delay in freeze-up and earlier break-up, leading to a lengthened open water period for all of the communities examined.
La enfermedad del alma en el filósofo tardoantiguo Evagrio Póntico: entre ignorancia y "filautía"
Authors: Hernán Vázquez Santiago
Published: May 2018

El tema de la enfermedad del alma constituye en el pensamiento del filósofo cristiano tardoantiguo, Evagrio Póntico, un tópico fronterizo entre las dos grandes áreas temáticas en que su obra puede ser dividida: la psicoespiritual y la metafísica. Reflexionar e intentar delimitar el origen y el estado de enfermedad en Evagrio implica, en efecto, prestar atención a un tópico transversal de su obra: la ignorancia. La consideración de esta condición psicoespiritual que en la metafísica evagriana constituye la consecuencia inmediata de la caída original del nous de la Unidad y la razón de su unión con un cuerpo, resulta necesaria para lograr una delimitación conceptual coherente del concepto de enfermedad en Evagrio. De igual modo, comprender cómo y de qué manera la ignorancia está en el origen del desorden pasional que opera en los estados de desequilibrio psíquicos tan minuciosamente detallados por nuestro pensador, implica considerar su vínculo causal con el amor desordenado de sí o filautía. En el esquema evagriano ésta constituye, a su vez, el origen común de aquellos pensamientos malvados y desequilibrantes que son la actividad cognitiva característica del estado de enfermedad y que nuestro autor llama logismoi.
Mito, historia y razón: entre Schelling y Adorno
Authors: Ferrer Diogo
Published: May 2018

Este artículo fundamenta la tesis de que el descubrimiento de elementos inconscientes en la base de la consciencia y de sus procesos de formación propició desde Kant una visión esencialmente crítica del sentido de la historia y una creciente comprensión del papel de la mitología para la conciencia humana. El estudio de este movimiento de crítica de la razón parte 1) de algunos descubrimientos de la filosofía clásica alemana sobre las presuposiciones de la consciencia que condujeran 2) a la comprensión de la historia como “caída”. La análisis de Schelling de los marcos del pasado —ruinas, megalitos y textos arcaicos— muestran así a la conciencia histórica asentada sobre un pasado inmemorial, del que se libra mediante una revelación. 3) La discusión de la mitología como fenómeno esencial a la conciencia histórica tiene como conclusión, según Schelling, la interpretación literal o “tautegórica” del mito, y 4) una concepción esencialmente mitológica del lenguaje y del significado en general. 5) Las concepciones de Schelling son comparadas con algún pensamiento filosófico sobre la historia en el siglo XX, a saber, la tesis de Husserl sobre la relación entre historia y conciencia y 6) con las concepciones de la relación entre mito y Aufklärung de Adorno y Horkheimer. Como conclusión, 7) la filosofía de la identidad de Schelling se contrasta con la concepción adorniana de lo no-idéntico, en lo que se refiere especialmente con la comprensión de la historia y del tiempo y la relación de la conciencia europea con la colonización y la violencia.
El concepto de motivación en la fenomenología hermenéutica del joven Heidegger
Authors: Garcés Ferrer Rocío
Published: May 2018

El presente artículo elucida el papel metodológico que juega el término «motivación» en la transformación hermenéutica de la fenomenología llevada a cabo por el joven Heidegger. A tal efecto, comenzaré con el análisis del concepto de motivación en la fenomenología de Husserl para apreciar después su inflexión hermenéutica en la filosofía de Heidegger. En un segundo momento, prestaré una especial atención a la importancia que tiene la motivación en el surgimiento de las nociones metodológicas más importantes de la fenomenología hermenéutica, como son la «destrucción», la «indicación formal» y la «preconcepción». Todo ello me conducirá, finalmente, a reformular el problema fenomenológico sobre la motivación de la reducción en términos hermenéuticos; esto es: a mostrar la necesidad de que exista una motivación en la experiencia fáctica para acceder a la esfera originaria del sentido. De tal modo que la experiencia filosófica fundamental del cuestionamiento radical (Fraglichkeit) pueda ser leída en términos de una epoché hermenéutica, la cual, a diferencia de la reducción, concierne directamente a la existencia misma del que pregunta.

Si esto es un cuerpo: de la ontología política a una ética posible
Authors: Periáñez Llorente Luis
Published: May 2018

En el presente artículo se explora el lugar de Lo que queda de Auschwitz en el proyecto Homo sacer, comenzado por Giorgio Agamben en 1995. Tal exploración parte de la comprensión del proyecto como ontología política, de la exposición de su deuda con la filosofía del lenguaje previa del autor, y de las pretensiones éticas del mismo, y acaba por localizar algunos de sus movimientos fundamentales, tales como la conformación de categorías ontológicas a partir de figuras históricas capaces de mostrar el “arcanum imperii” del sistema político al que pertenecen. Como resultado, el artículo muestra la raíz metafísica del análisis del sujeto llevado a cabo en Lo que queda de Auschwitz, y la forma en que ésta afecta a la apuesta ética del italiano, abriendo así una vía crítica en la que se jueguen sus posibles reformulaciones.
Software support for cost calculation - application to the agricultural sector
Authors: Hudáková Stašová Lenka
Published: May 2018

Calculation of product costs is the source of information on the costs of selected produced products with great explanatory power. In current practice, the overhead costs on farms are monitored and calculated by species. They are allocated using an allocation base (average state of the animals, harvested area in hectares) or are converted using direct costs of the activity as an allocation base. With the current high level of overheads, this method cannot be considered effective. Only type classifications are monitored and are therefore anonymous in relation to activities. We consider high overhead costs as a good reason for implementing and using the methods of Activity Based Costing. In this paper we present a proposed model of Activity Based Costing for its use in agriculture, created in MS Excel. We create the model as a basic version, which can be more closely defined depending on the particular conditions of the business implementing the model. We complete the general model for better illustration with figures on costs. We present a comparison of model results with the traditional approach of calculating costs in agriculture. One of the biggest benefits of the ABC system is the binding of costs from accounts, activities performed and the cost of products in one system. We present a statistical comparison of model results with the traditional approach of calculating costs in agriculture.
A Study About the Relationships Between Perceived Leadership and Job Satisfaction in Fuel Sector
Authors: AYRANCI Evren , DEMIR Serhat
Published: May 2018

Due to their popularity, there are countless studies about job satisfaction and leadership. With this aspect in mind, this study scrutinizes relationships between perceived leadership and job satisfaction in a rather less considered context: fuel sector. The participants of the study are workers of fuel stations, gathered from specific regions of Istanbul. According to results obtained, their job satisfaction depends on four factors; namely task, and social, managerial and institutional aspects. Another result reveals that they perceive their immediate managers as leaders and this perceived leadership is also made of four factors: inspirational, productive and laissez-faire styles, and success orientation. Although perceived leadership is unable to affect job satisfaction completely, there are some partial effects. A look on these partial effects reveals that most items of inspirational and laissez-faire leadership styles are effective on worker’s job satisfaction. While success orientation feature of leadership can affect job satisfaction via one of its items solely, productive leadership style completely fails to affect the mentioned job satisfaction.

An Investigation of Primary Student Teachers’ Drawings of the Human Internal Organs
Authors: Çakıcı Yılmaz
Published: May 2018

The aim of this study is to investigate primary student teachers’ drawings of the human internal organs, e.g. location, size and presence of organs (heart, lungs, stomach, liver, kidneys, pancreas and intestines etc.) This research was conducted with 104 primary teacher candidates studying in the Faculty of Education at Trakya University during the 2016-2017 academic year. The research data was obtained through the use of drawings and interviews with selected students. The findings revealed that, as expected, all students showed the heart, lungs and stomach in their drawings. The most frequently illustrated other human internal organs were intestines, liver, kidneys, pancreas and spleen respectively. However, too many of them were not scientifically acceptable in terms of the location and size. There are many points in the students’ drawings that need to be underlined by teachers during the teaching-learning process in class.
From Learning Theory to Academic Organisation: The Institutionalisation of Higher Education Teaching Assistant Position in China
Authors: Chandrakar Chandu Lal , Bentao Yuan
Published: May 2018

This exploratory study critically investigates the teaching assistant regulations of higher education institutions of China. On the basis of content analysis of the teaching assistant regulations of five premier universities of China this study analyses the possible discrepancies that might compromise the principles of transparency, equal opportunity and encouraging excellence as stipulated in the vision, mission, and goal of the regulations. Teacher assistants do make more than two third of the academic staff at the universities in China. Besides, China has a second largest higher education system in terms of scale in the world. Practices of sharing skills and imparting knowledge at these institutions have been intermediated by a semi-institutionalized position, called ‘teacher assistants’. It’s therefore, the informal submission of assignments without record at the PhD level questions the purpose of integrity and academic freedom of the higher education at the universities. On the basis of an instrumentalised framework guided by the dimensions of decision making and learning organization theories this study using content analysis has formulated the recommendations for the institutions while selecting and training the students as teaching assistants. A critical but logical illustration of the teaching assistant regulations has also been detailed regarding academic integrity in this study.
Inhibitory factors and problems associated with uniform access to cancer care: Perceptions of certified nurse specialists in cancer nursing
Authors: Kitajima Masaki , Miyata Chiharu , Kinoshita Ayae , Arai Hidenori
Published: May 2018

To elucidate the factors that obstruct uniform accessibility to care when oncology clinical nurse specialists (OCNSs) engage in medical care and to devise solutions for these obstructions. OCNSs enhance the quality of medical care, conduct activities as multidisciplinary coordinators, and provide public policy-related advice to maintain and improve the general population’s health. Therefore, OCNSs’ opinion is highly regarded, particularly in clinical setting. This study extracted and investigated the perceptions of OCNSs regarding factors inhibiting uniform access to care on the basis of a questionnaire with open-ended questions. Upon receiving the institutional review board’s approval, a questionnaire was distributed among 483 participants. Of these, 211 OCNSs affiliated with Core Oncology Centers who returned the filled questionnaire forms were enrolled. The recovery and effective response rates were 43.7% and 63.5%, respectively. Data were collected from the survey forms and subjected to qualitative and descriptive analyses. Inhibitory factors were categorized into the following five categories: (1) education and training systems; (2) medical specialties and workforce; (3) standard of medical care; (4) insufficient understanding on the part of administrators and the organization; and (5) policy. Each factor was further categorized into subcategories to elucidate the factors inhibiting universal access to care. Factors related to education and training systems affect factors related to medical specialties and manpower, leading to an imbalanced distribution of personnel between regions and facilities.

Purpose: Self-care and associated decisions for therapeutic recommendations have been a focus of attention recently in Korea. The purpose of this study was to address the dimensionality and reliability of a Korean version of Self-care of Heart Failure Index (SCHFI v.6.2), a measure of self-care of patients with heart failure within a clinical context.Methods: The study sample completed 120 surveys that consisted of demographic variables and the SCHFI v.6.2, which was created to measure self-care maintenance, self-care management, and self-care confidence in HF patients. Confirmatory factor analysis using Mplus verified a robust structural fit of the three dimensionality for each subscale.Results: Self-care maintenance, CFI = .92, TLI = .88, SRMR = .06, RMSEA = .07; self-care management, CFI = .93, TLI = .78, SRMR = .05, RMSEA = .24; self-care confidence, CFI = .95, TLI = .92, SRMR = .05, RMSEA = .13. Multidimensionality yielded the self-care maintenance scale having 4-factor structures, while each self-care management and confidence scale had a unidimensionality. Reliability estimates using methods compatible with each scale’s dimensionality were adequate to high, ranging from .71 to .96.Conclusions: Psychometric testing of the SCHFI demonstrates a sound model fit, with desirable reliability estimates given each scale dimensionality, using Cronbach’s alpha coefficient and alternative options.

Narratives as Catalysts for Transformation and Social Action Planning within the Hong Kong Indonesian Migrant Community
Authors: Martyn Howard Lorne
Published: May 2018

This paper discusses the use of written and oral narratives, composed as classroom assignments by adult Indonesian migrant workers, sojourning in Hong Kong. Individually written narratives embody group-common elements that can be acted upon, thus becoming catalysts for personal growth and for group social action planning. Personal growth includes refocusing personal identity away from the societally imposed and devalued ‘domestic helper’, toward identities that offer self-empowerment. Redefining personal identity within a group learning situation also builds group identity which can be directed toward confronting hegemonic forces. This is done on four fronts: firstly, by claiming the symbolic right of cultural space and by demanding respect within the larger Hong Kong community; secondly, by publicly agitating against government policies, such as human rights and minimum wage legislation, that migrant workers believe disadvantage them; thirdly, by increasing ability in English, Cantonese, and basic computer applications that specifically meet Indonesians’ work requirements and interests; and finally, by building the capacity to confront employers in claiming government guaranteed minimum wages and rest days. Through these actions, the opportunity for both personal and societal transformation is created.Data was collected through journal narratives and semi-structured qualitative interviews with migrants who were taking weekly English languages classes at a small private training center in Hong Kong.

A Novel Low-Cost Indicator of Student Perseverance and Its Association with College Student Academic Performance
Authors: Yerger David B. , Stephenson Amber L.
Published: May 2018

Within the research literature investigating how student characteristics related to perseverance impact academic outcomes, leading scholars have encouraged the development of new measurements, both survey and non-survey based. We introduce here an innovative non-survey-based measurement, derived from common higher education variables, that reflects the perseverance construct. The created perseverance proxy is easily created and explainable to audiences with minimal statistical background. The variable was used to analyze academic outcomes at a mid-sized public university in the United States. The perseverance proxy strongly positively associates with academic outcomes, as measured both by GPA and odds of academic probation, in multivariate analysis across both genders. The perseverance proxy explains more of the variation in academic outcomes than any of the cognitive and financial aid variables used in the analysis. The technique for constructing the perseverance proxy is easily replicated at any college or university having data on students’ high school ranking and college admission exam scores.

A Legislature is one of the most important bodies in a country, because in addition to its primary duty of passing legislations it also monitors the executive body and holds it accountable for the execution of its duties. Due to this responsibility the national legal systems have granted legal protection for members of the legislature to aid them to carry out their assigned responsibilities in accordance with the constitution, this protection is known as Parliamentary immunity.We have clarified the concept of Parliamentary immunity and its legal nature, in addition we have also discussed its types (objective and procedural) and made clear the differences between them. In addition, we pointed out the procedure of lifting the immunity, legal reasons that require it be lifted and the position of some constitutions in regard it.We have also explained and indicated whether Parliamentary immunity was successful in protecting the legislature from intimidation or strong-arming of the executive authority.
Technical Efficiency of Public Service Hospitals in Indonesia: A Data Envelopment Analysis (DEA)
Authors: Harmadi Sonny , Irwandy Irwandy
Published: May 2018

In order to promote efficiency and the development of hospitals’ services, the Government of Indonesia has issued specific policy which require all of the government-owned hospitals to be managed based on the principals applied in public services agency (Badan Layanan Umum/Badan Layanan Umum Daerah (BLU/BLUD)). The policy of BLU/BLUD is to grant each hospital authorization in managing their funds and resources under the principles of public accounting. Unfortunately, not all government-owned hospitals were granted BLU/BLUD authorization, especially hospitals outside of Jakarta, because local government did not wish to lose one of their main income. The main focus of this research is to calculate the efficiency of the hospitals of which have been granted BLU/BLUD, since one of the main purposes of BLU/BLUD is to provide high quality and efficient health care to the public. The measurement of hospitals’ efficiency is not an easy thing to do, since there are so many inputs and outputs that were related to each other. Which is why, this research is measuring the efficiency level using the DEA (Data Envelopment Analysis) which is able to provide efficiency calculation with multiple inputs and outputs. With the total samples of 82 BLU/BLUD hospitals, this research concluded that the average of hospital’s efficiency score is still on the level of 78.9 % out of 100%.
