National ETD Repository Evaluation Using Web Analyzer
Authors: Chakravarty Rupak
Published: September 2018

ETDs are the Swiss-army-knife which has unearthed the shades of grey by bringing forth the until now hidden research to the forefront of the world. ETDs powered by open source software like DSpace, EPrints build up information ecosystem for effective storage and retrieval of theses and dissertations which take years of hard work to culminate. Such systems need to be evaluated as its purpose gets defeated if users find it hard to retrieve desired information from it. Webometrics involves the study of the web through which one can analyze the number of hyperlinks, type and structure of the hyperlinks, website usage and its effectiveness. The present article is an attempt to assess the performance of online portal of the national ETD repository of India by using Web Analyzer Test Score (WATS). It also highlights the status of Open Access (OA) ETD repositories with respect to other OA content like research papers, conference papers, etc. along with exploring the software used for Indian ETD Repositories. The overall score of the webometric analysis was found to be 6.4.
Numerical Studies for the Effects of Viscoelastic Constitutive Parameters on the Extrudate Swell of Plastic Micro-Tubes
Authors: Ren Zhong , Huang Xing Yuan , Xiong Zhi Hua
Published: September 2018

The effects of four difference viscoelastic constitutive parameters, i.e., viscosity, relaxation time, ε and ξ on the extrudate swell of plastic micro-tubes were studied by using the numerical method. Numerical results show that the extrudate swell of plastic micro-tube increases with the increase of the relaxation time, but decreases with the increase of ε and ξ. In addition, the extrudate swell ratio of plastic micro-tube is not changed with the increase of the viscosity of melt. To ascertain the effect of four different viscoelastic constitutive parameters on the extrudate swell of plastic micro-tube, the physical field distributions, i.e., flow velocity, shear rate, shear stress, and first normal stress difference distributions of melt were obtained, respectively. Results show that the extrudate swell phenomenon of plastic micro-tube is closely dependent on the elastic energy storage of melt induced by the above mentioned physical field distributions, especially at the outlet of die.
The Effect of Lattice Orientation on the Film Hole Deformation of Nickel-Based Single Crystal Plate Specimen
Authors: Cao Gang , Yang Yan Qiu , Wen Zhi Xun , Yue Zhu Feng
Published: September 2018

Based on the crystal plasticity theory, numerical simulation is implemented to calculate the equivalent strain field, resolved shear stress and sectional area of the cooling film hole. The results indicate that plastic strain and the distribution of resolved shear stress caused by multi-hole interference varies with different crystal orientations. Orientation [001] indicates relatively larger deformation than rest orientations. In the case of orientation [001], deformation concentrated at resolved shear stress zone between the holes, while orientation [011] and [111] appeared at the top and bottom of holes. Under the condition of multi-hole, compared to the single hole, the sectional area has a significant increase for orientation [001]. The sectional area changes substantially similar for orientation [011] and [111], but the sectional area is smaller than that in the case of single hole, with a sharp contrast to the formation of orientation [001].
Influence of Process Parameters on Surface Roughness and Wettability of Aluminum-Matrix Materials
Authors: Du Wei Xiao , Zhan Li , Liu Feng , Shan Bao Zhen , Hwang W.
Published: September 2018

Super hydrophobic surface has a good application prospect in industry, agriculture and daily life. By controlling the concentration and etching time of hydrochloric acid, different rough structures were prepared on the aluminum-matrix surface, and the relationship of roughness & CA were established to explore the influence of process parameters on the surface roughness and surface wettability. It is found that the concentration and time of hydrochloric acid significantly affect the surface roughness and contact angle (CA). When the concentration of hydrochloric acid is 1.5mol/L and the etching time is 90s, the surface roughness is the best and the maximum CA is obtained. After sodium hydroxide treatment, the hierarchical structure with micro and macro scale was formed, which significantly reduced the contact area between the water droplet and the surface, and the maximum roughness and CA was achieved. The relationship between surface roughness and CA shows that the roughness can amplify the hydrophile/hydrophobicity. Therefore, a better surface of superhydrophobic surface can be obtained by increasing the surface roughness.
Delirium onset within a palliative care programme: nursing care for the patient and family
Authors: Caleffi Dalia , Fabbo Andrea , Gelati Luca , Monti Cinzia
Published: September 2018

Delirium is a neurocognitive syndrome correlated with increased risk of hospitalization, functional and cognitive impairment, and mortality. Patients under palliative treatment regime are at higher risk of developing the syndrome due to their debilitated physical condition. In this context delirium is one of the most frequent complications, affecting around 85% of people at the end of the life. It augments the distress of the expiring individual and their family, aggravating suffering and compromising the quality of the life of the terminally ill people. The aim is to prevent the incidence of delirium identifying people at risk. If an episode of delirium occurs, it is essential to identify it with specific clinical assessment tools, to assess and to treat reversible causes in combination with enviromental, psychological and pharmacological intervention to control the symptoms. The close supporting role of the nurse within the family group confers them a fundamental role in the recognition and management of delirium. It is essential to analyse the peculiarities of assistance for patients under palliative treatment affected by delirium, together with their family. To provide personalized treatment that offers support, relief and hope, considering the person as a whole within the family setting, nurses can use the taxonomy of Nanda international classification of nursing diagnosis (Nanda-I), Nursing outcomes classification (Noc) and Nursing interventions classification (Nic).

Authors: Rood Carla , Van den Berg Deon , Niemann Wesley , Meyer Arno
Published: September 2018

Orientation: Firms can no longer rely on their own internal capabilities to operate in dynamic business environments but rather depend on buyer–supplier relationships to resolve and survive supply chain disruptions.Research purpose: The purpose of this study was to explore the underlying role of personal buyer–supplier relationships in a supply chain disruption context.Motivation for the study: Previous research studies have focussed solely on the role of business relationships in a supply chain disruption context, while neglecting personal relationships.Research design, approach and method: A generic qualitative research strategy was used for this purpose. Eighteen semi-structured interviews were conducted with nine buyers and nine suppliers of logistics services who were involved in personal relationships during supply chain disruptions.Main findings: The findings of this study indicate the attributes that must be present for a personal relationship to form in a supply chain disruption context, along with the various advantages and disadvantages that are derived from personal relationships in times of supply chain disruption.Practical/managerial implications: For managers, this study identifies various attributes, advantages and disadvantages of personal relationships in supply chain disruptions, therefore equipping managers to extract value from personal relationships in supply chain disruptions.Contribution/value-add: Academically, this study expands the literature by being one of the first empirical studies to conduct research on the role of buyer–supplier personal relationships in the third-party logistics supply chain disruption context.

A lo largo de los diferentes periodos históricos, los creadores han hecho de su contexto su fuente de inspiración. Sus obras pueden considerarse resultado de la unión de diferentes referencias representativas de su entorno personal, social e histórico. Analizando los fragmentos conformadores de estos trabajos, puede estudiarse a estos autores y sus circunstancias, de la misma forma que es posible la reconstrucción de la historia cultural mediante el análisis de sus ruinas. Si bien la posmodernidad se considera como la época donde este método de creación artística se hace más evidente por su carácter visual, esta investigación propone ampliar dicho enfoque a las diferentes etapas del arte a través de diversos ejemplos.
POLÍTICAS PÚBLICAS EM SUICÍDIO: DO PATERNALISMO CLÁSSICO AO PATERNALISMO LIBERTÁRIO E NUDGING
Authors: Tangerino Davi De Paiva Costa , Cabral Gabriel , Olive Henrique
Published: September 2018

Os índices dos eventos de suicídio vêm progressivamente aumentando por todo o mundo, demandando de entes públicos a tomada de decisões quanto à implementação de medidas efetivas para coibi-los. As políticas públicas tradicionalmente utilizadas, como a inserção de barreiras físicas em hotspots ou a promoção de campanhas de conscientização, não costumam apresentar resultados satisfatórios, apesar do alto custo de implementação. Tendo em vista este contexto, pretende-se neste artigo promover uma via alternativa de intervenção. Para isto, primeiro debatemos a via do nudging, sua forma de operação e o paternalismo de Estado; segundo, debruçamo-nos sobre os elementos concretos do fenômeno, realizando análises e cruzamentos de dados do Ministério da Saúde do Brasil e do Instituto Brasileiro de Geografia e Estatística, bem como se utilizando de estudos específicos nacionais e estrangeiros para a identificação de características e padrões dos eventos suicidas; em seguida, debatemos as experiências estrangeiras no desenvolvimento e aplicação de políticas públicas em seu enfrentamento. Com estas informações, discutimos medidas em forma de nudges para a gestão do fenômeno do suicídio, com a pretensão de promover o método e incentivar novas propostas de políticas públicas para este e outros problemas na esfera da gestão pública.
RAZÃO, EMOÇÃO E DELIBERAÇÃO: AS ADEQUAÇÕES REGIMENTAIS DO SUPERIOR TRIBUNAL DE JUSTIÇA PARA A FORMAÇÃO DE PRECEDENTES EFICAZES
Authors: Panutto Peter , Chaim Lana Olivi
Published: September 2018

Trata-se da implantação pelo CPC de 2015 de um sistema de precedentes judiciais e da consequente necessidade de alteração nos mecanismos institucionais dos tribunais para efetiva criação e cumprimento de precedentes. Destacou-se o papel dos mecanismos mentais pertinentes à formação da decisão que levam um indivíduo a produzir uma opinião naturalmente enviesada e os eventuais resultados nocivos desses elementos para a tomada da decisão. Demonstrou-se a importância da atuação deliberativa com o confronto de argumentos como alternativa para afastar os efeitos nocivos das decisões individualizadas em um colegiado. Realizou-se um estudo das normas do RI do STJ para averiguar a existência de mecanismos de votação colegiada para se chegar a uma decisão institucional. Este tribunal foi escolhido em razão de seu pioneirismo e interesse na adaptação de seu RI ao CPC de 2015. O objetivo do artigo é demonstrar que a não adequação do procedimento deliberativo dos tribunais acarretará na ineficácia do sistema de precedentes, pois tais decisões representarão o entendimento individual do julgador, sem o estabelecimento de um entendimento institucional sobre o tema. O método adotado foi o hipotético-dedutivo, mediante análise crítica da necessidade de aprimoramento dos procedimentos de criação e respeito dos precedentes. Como resultado verificou-se que o RI do STJ formulou regras que facilitam a tomada de voto bem informado, diminuindo-se o viés individual na deliberação colegiada, mas ainda precisa ser aprimorado para a criação de mecanismos visando a interação entre os magistrados, para o pleno aproveitamento de toda a potencialidade do colegiado.

Published: September 2018

O objetivo deste artigo é avaliar se o Projeto de Lei Complementar 488/2017 do Senado (PLS 488/2017) pode aumentar a permeabilidade dos criadores de políticas públicas ao uso de evidências, sobretudo comportamentais. Começamos por apresentar o PLS 488/2017, sua proposta de alteração legislativa e as razões para a sua proposição. Em seguida, discutimos o que pode ser considerado uma política pública, tanto da perspectiva acadêmica quanto da perspectiva do projeto de lei, demonstrando seu alcance. Depois, abordamos o movimento de políticas públicas baseadas em evidências, expondo seu surgimento, as formas de se compreender o uso de evidências nas políticas, algumas críticas e estratégias importantes para respondê-las. Passamos para o uso de evidências comportamentais nas políticas públicas, primeiro abordando os nudges, que são um tipo de política comportamental relevante no debate acadêmico, e, depois, defendendo um uso mais amplo das evidências comportamentais nos diversos estágios das políticas públicas. O uso de evidências nas políticas pode aumentar a efetividade das políticas e melhorar a atuação do Estado. Concluímos que o PLS 488/2017 abre espaço para o uso de evidências comportamentais em alguns de seus dispositivos, sobretudo na tomada de decisão e na implementação da política, e que o projeto pode ser visto como um estímulo ao diálogo entre os criadores de políticas e os coletores de dados e evidências comportamentais relevantes.
OS PROGRAMAS DE INTEGRIDADE PARA CONTRATAÇÃO COM A ADMINISTRAÇÃO PÚBLICA ESTADUAL: NUDGE OU OBRIGAÇÃO LEGAL? UM OLHAR SOBRE AS DUAS PERSPECTIVAS
Authors: Araripe Cíntia Muniz Rebouças de Alencar , Machado Raquel Cavalcanti Ramos
Published: September 2018

O relacionamento do setor privado com a Administração Pública tem passado por profundas transformações, sendo uma delas o incentivo dos Poderes à implementação de programas de integridade nas empresas. Por serem custosos e envolverem, no mais das vezes, transformação de cultura, tais programas vinham sendo implantados tão-somente por imperativos de mercado, figurando-se de extrema valia uma política pública baseada em nudges. Sucede que alguns Estados têm exigido os programas de integridade para contratação com a sua Administração. Tem-se por objetivo geral averiguar como seria uma política pública baseada em nudges e outra em exigências legais, confrontando as duas técnicas, inclusive sob a ótica de sua constitucionalidade e oportunidade. Como objetivos específicos, destacam-se: a) compreender a política pública baseada em nudges; b) examinar a constitucionalidade e a oportunidade da exigência, por lei estadual, de programas de integridade para contratar com a Administração; c) debater ambas as técnicas, contrapondo os argumentos. Utilizar-se-á de metodologia de cunho dedutivo teórico, prescritivo e dialético. Remonta a outubro/2017 a lei estadual que primeiro veio obrigar as empresas a implementarem tais programas, sendo a discussão ainda incipiente e, portanto, oportuna e atual. Apesar de o STF não ter sido instado a se manifestar sobre a exigência, por lei estadual, de programas de integridade na contratação com a Administração Pública, a dicção que se extrai dos seus julgados é pela sua inconstitucionalidade. Na doutrina, não há consenso sequer sobre a sua oportunidade. O ordenamento jurídico brasileiro, entretanto, dispõe de ferramentas outras, menos controversas, das quais se pode fazer uso.
CONSILIÊNCIA E A POSSIBILIDADE DO NEURODIREITO: DA DESCONFIANÇA À RECONCILIAÇÃO DISCIPLINAR
Authors: Gontijo de Oliveira Thaís De Bessa , Cardoso Renato Cesar
Published: September 2018

O artigo tem por objetivo revisitar a origem do afastamento disciplinar que ocorre entre as Ciências Naturais, Ciências Sociais e Humanidades. Esse afastamento levou ao atual modelo de hiperespecialização que, embora tenha impulsionado um notável avanço em cada uma das disciplinas, teve como consequência a fragmentação do próprio conhecimento e a perda da coerência entre cada uma dessas partes. Esse modelo mostra sinais de esgotamento, já que não é capaz nem enfrentar questões filosóficas fundamentais, nem tampouco de apresentar soluções satisfatórias para os grandes problemas humanos de contemporâneos. Nesse contexto, apresenta-se a Consiliência, que propõe a recuperação da coerência entre todos os ramos do conhecimento, tanto na tarefa de conhecer nossa própria humanidade, quanto na tarefa de apresentar respostas a esses grandes problemas. Como conclusão, percebeu-se que, para o Direito, esse movimento de aproximação pode ter consequências disruptivas, já que as explicações das Ciências Cognitivas para o comportamento humano podem desafiar noções fundamentais com as quais o Direito opera. Equacionar tudo isso é a tarefa que atribui-se ao Neurodireito. A originalidade do artigo reside na recuperação das origens para o afastamento disciplinar, e as razões para sua superação, sempre dentro do contexto do Direito. Essa revisão evidenciou a tarefa de tornar todo esse conhecimento coerente, ou consiliente. Dentro das Ciências Jurídicas, essa é a tarefa do Neurodireito.

CNN-BASED INITIAL LOCALIZATION IMPROVED BY DATA AUGMENTATION
Authors: Mueller M. S. , Metzger A. , Jutzi B.
Published: September 2018

Abstract. Image-based localization or camera re-localization is a fundamental task in computer vision and mandatory in the fields of navigation for robotics and autonomous driving or for virtual and augmented reality. Such image pose regression in 6 Degrees of Freedom (DoF) is recently solved by Convolutional Neural Networks (CNNs). However, already well-established methods based on feature matching still score higher accuracies so far. Therefore, we want to investigate how data augmentation could further improve CNN-based pose regression. Data augmentation is a valuable technique to boost performance on training based methods and wide spread in the computer vision community. Our aim in this paper is to show the benefit of data augmentation for pose regression by CNNs. For this purpose images are rendered from a 3D model of the actual test environment. This model again is generated by the original training data set, whereas no additional information nor data is required. Furthermore we introduce different training sets composed of rendered and real images. It is shown that the enhanced training of CNNs by utilizing 3D models of the environment improves the image localization accuracy. The accuracy of pose regression could be improved up to 69.37 % for the position component and 61.61 % for the rotation component on our investigated data set.
DEEP CROSS-DOMAIN BUILDING EXTRACTION FOR SELECTIVE DEPTH ESTIMATION FROM OBLIQUE AERIAL IMAGERY
Authors: Ruf B. , Thiel L. , Weinmann M.
Published: September 2018

Abstract. With the technological advancements of aerial imagery and accurate 3d reconstruction of urban environments, more and more attention has been paid to the automated analyses of urban areas. In our work, we examine two important aspects that allow online analysis of building structures in city models given oblique aerial image sequences, namely automatic building extraction with convolutional neural networks (CNNs) and selective real-time depth estimation from aerial imagery. We use transfer learning to train the Faster R-CNN method for real-time deep object detection, by combining a large ground-based dataset for urban scene understanding with a smaller number of images from an aerial dataset. We achieve an average precision (AP) of about 80 % for the task of building extraction on a selected evaluation dataset. Our evaluation focuses on both dataset-specific learning and transfer learning. Furthermore, we present an algorithm that allows for multi-view depth estimation from aerial image sequences in real-time. We adopt the semi-global matching (SGM) optimization strategy to preserve sharp edges at object boundaries. In combination with the Faster R-CNN, it allows a selective reconstruction of buildings, identified with regions of interest (RoIs), from oblique aerial imagery.

Abstract. The integrated photogrammetric mapping system flown on the last three Apollo lunar missions (AS15, AS16, and AS17) in 1971 and 1972 incorporated a Metric (mapping) Camera, a high-resolution Panoramic Camera, and a star camera and laser altimeter. The U.S. Geological Survey’s Astrogeology Science Center, the Intelligent Robotics Group of the NASA Ames Research Center, and Arizona State University are working together in an ongoing collaboration to achieve the most complete cartographic development of Apollo mapping system data into versatile digital map products. These will enable a variety of scientific/engineering uses of the data including mission planning, geologic mapping, geophysical process modelling, slope dependent correction of spectral data, and change detection. After a brief discussion of the origins of the mapping system, we describe the Metric and Panoramic cameras, processing of the associated image and support data, work to photogrammetrically control the Metric Camera images, and future plans.
SEMANTIC LABELING OF STRUCTURAL ELEMENTS IN BUILDINGS BY FUSING RGB AND DEPTH IMAGES IN AN ENCODER-DECODER CNN FRAMEWORK
Authors: Iwaszczuk D. , Koppanyi Z. , Gard N. A. , Zha B. , Toth C. , Yilmaz A.
Published: September 2018

Abstract. In the last decade, we have observed an increasing demand for indoor scene modeling in various applications, such as mobility inside buildings, emergency and rescue operations, and maintenance. Automatically distinguishing between structural elements of buildings, such as walls, ceilings, floors, windows, doors etc., and typical objects in buildings, such as chairs, tables and shelves, is particularly important for many reasons, such as 3D building modeling or navigation. This information can be generally retrieved through semantic labeling. In the past few years, convolutional neural networks (CNN) have become the preferred method for semantic labeling. Furthermore, there is ongoing research on fusing RGB and depth images in CNN frameworks. For pixel-level labeling, encoder-decoder CNN frameworks have been shown to be the most effective. In this study, we adopt an encoder-decoder CNN architecture to label structural elements in buildings and investigate the influence of using depth information on the detection of typical objects in buildings. For this purpose, we have introduced an approach to combine depth map with RGB images by changing the color space of the original image to HSV and then substitute the V channel with the depth information (D) and use it utilize it in the CNN architecture. As further variation of this approach, we also transform back the HSD images to RGB color space and use them within the CNN. This approach allows for using a CNN, designed for three-channel image input, and directly comparing our results with RGB-based labeling within the same network. We perform our tests using the Stanford 2D-3D-Semantics Dataset (2D-3D-S), a widely used indoor dataset. Furthermore, we compare our approach with results when using four-channel input created by stacking RGB and depth (RGBD). Our investigation shows that fusing RGB and depth improves results on semantic labeling; particularly, on structural elements of buildings. On the 2D- 3D-S dataset, we achieve up to 92.1 % global accuracy, compared to 90.9 % using RGB only and 93.6 % using RGBD. Moreover, the scores of Intersection over Union metric have improved using depth, which shows that it gives better labeling results at the boundaries.

Abstract. We study and analyse performance of a system for direct reflectance measurements from a drone. Key instruments of the system are upwards looking irradiance sensor and downwards looking imaging spectrometer. Requirement for both instruments is that they are radiometrically calibrated, the irradiance sensor has to be horizontally stabilized, and the sensors needs to be accurately synchronized. In our system, irradiance measurements are done with FGI Aerial Image Reference System (FGI AIRS), which uses novel optical levelling methodology and can compensate sensor tilting up to 15°. We performed SI-traceable spectral and radiance calibration of FPI hyperspectral camera at the National Physical Laboratory NPL (Teddington, UK). After the calibration, the radiance accuracy of different channels was between ±4 % when evaluated with independent test data. Sensors response to radiance proved to be highly linear and was on average 0.9994 for all channels. The spectral response calibration showed side peaks on several channels that were due to the multiple orders of interference of the FPI and highlighted the importance of accurate calibration. The drone-based direct reflectance measurement system showed promising results with imagery collected over Jokioinen agricultural grass test site, Finland. AIRS-based image- and band wise image adjustment provided homogenous and seamless image mosaics even under varying illumination conditions and under clouds.
COMPARISON OF TWO METHODS FOR 2D POSE ESTIMATION OF INDUSTRIAL WORKPIECES IN IMAGES – CNN VS. CLASSICAL IMAGE PROCESSING SYSTEM
Authors: Siegfarth C. , Voegtle T. , Fabinski C.
Published: September 2018

Abstract. Today, automatic image analysis is one of the basic approaches in the field of industrial applications. One of frequent tasks is pose estimation of objects which can be solved by different methods of image analysis. For comparison two of them have been selected and investigated in this project: Convolutional Neural Networks (CNNs) and a classical method of image analysis based on contour extraction. The main point of interest was to investigate the potential and limits of CNNs to fulfil the requirements of this special task regarding accuracy, reliability and time performance. The classical approach served as comparison to a state-of-the-art solution. The workpiece for these investigations was a commonly used transistor element. As database an image archive consisting of 9000 images with different illumination and perspective conditions has been generated. One part was used for training of the CNN and the creation of a so-called shape model respectively, the rest for the investigation of the extraction quality. With CNN technique two different approaches have been realised. Even if CNNs are predestined for classification this method delivered insufficient results. In a more sophisticated approach the system learns the parameters of an affine transformation including the sought-after parameters of translation and rotation. Our experiments confirm that CNNs are able to obtain at best only a medium accuracy of rotation angles (about ± 2°), in contrast to the classical approach (about ± 0.5°). Concerning the determination of translations both methods deliver comparable results, about ± 0.5 pixel from CNN and about ± 0.4 pixel from classical approach.
INDEPENDENT ON-ORBIT GEOMETRIC CALIBRATION OF OPTICAL SATELLITE BASED ON WEIGHTED VIRTUAL OBSERVATION
Authors: Yang B. , Pi Y.
Published: September 2018

Abstract. On-orbit geometric calibration is an essential technology to improve the initial geometric accuracy of the optical satellite images. The presented methods usually take the absolute constraint from calibration site data into the imaging model to deduce exact systematic error parameters. However, the characteristic of strong dependence on the high-accuracy calibration site data leads to limitations such as high cost and poor efficiency of these conventional methods. In order to make better use of the mutual constraints among the images, and to get rid of the dependence of calibration site, we conduct an investigation on the on-orbit geometric calibration using the mutual constraints of overlapped images instead of absolute constraint from calibration site for optical satellite. To ensure the stable solution of calibration equation, a weighted virtual observation is introduced into calibration model to improve its condition. The method is verified with a pair of simulated images, and the satisfactory results indicate that the method is effective and reasonable.

Information Asymmetry, Adverse Selection, and Mechanism Design —The Case of Renrendai.com
Authors: Wang Han , Zeng Zhi Peng , Liu Ying , Peng Geng , Lv Fu Ben
Published: September 2018

The influence of information asymmetries and adverse selection on market breakdown is attracting considerable attention. Previous researches demonstrated that information asymmetries and adverse selection are critical issues in online peer-to-peer lending platforms, especially in emerging markets. We believe that information asymmetries can be mitigated through mechanism design. We compare two screening mechanisms, namely, “offline” and “online” mechanisms, by using a dataset from Renrendai.com. We determine that the problems attributed to information asymmetries play a negative role in market efficiency under the “online” mechanism, whereas the “offline” mechanism effectively mitigates these issues. Under the “offline” mechanism, potential borrowers can obtain loans with a high probability of approval and an interest rate that is lower by 0.02 than that under the “online” mechanism, and the default probability of their loans is reduced by 24% in comparison with that under the “online” mechanism.
Justice on the Western Frontier: The Death Penalty in Pre-Industrial Pittsburgh, 1754–1840
Authors: Lofquist William S.
Published: September 2018

With an execution moratorium in place, no executions this century, and declining public and political support, the death penalty is moribund in Pennsylvania. As it moves into history, this research documents and analyzes the history of the death penalty in Allegheny County. Focusing on the earliest chapter of that history, the pre-industrial era, two major patterns are observed. First is the role of the death penalty in early efforts to establish and legitimize federal, state, and military authority. Second, as that statemaking project brought a stable civil society into being, use of the death penalty focused more on protecting social relations.

Foi avaliada a presença de sujidades leves (insetos, ácaros e pelos de roedores) em alimentos extrusados para cães comercializados a granel e em embalagem fechada, bem como as condições ambientais de comercialização. Foram analisadas 25 amostras a granel e 25 embalagens fechadas. Quanto a sujidades leves, 34% tiveram alguma sujidade detectada, sendo 30% delas em alimentos comercializados a granel. A principal sujidade encontrada foram os fragmentos de insetos, 40% nas amostras a granel e 8% em embalagem fechada. Em relação à condição de comercialização, dos 16 comércios visitados, 4 tinham condições higiênicas sanitárias baixas com alimentos expostos ao ambiente, acesso a outros animais e local empoeirado. Condições ambientais inadequadas, como as observadas nos alimentos a granel, associadas à falta de boas práticas de comercialização, contribuem para o aumento da presença de vetores, como roedores e insetos.
The influence of nurses job dissatisfaction on adoption of Magnet status within hospitals
Authors: Manea Sawsan , Johnson Jessie , Wolsey Carolyn
Published: September 2018

Background: Hamad Medical Corporation (HMC) has a goal to achieve Magnet designation. Magnet status is a worldwide international award given to hospitals which demonstrate excellent quality of patient care, innovative professional nursing practices and effective nurse recruitment and retention patterns. To date, only 3 other hospitals in the Middle East have achieved this recognition; two in Saudi Arabia and one in Lebanon. Achieving Magnet status is highly influenced by nurses’ job satisfaction and commitment to their organization.Purpose: A literature review was used to identify factors contributing to nurses’ job dissatisfaction that may impede the adoption of the Magnet Program at HMC hospitals in Qatar.Findings: Five themes emerged from the review of literature representing the predominant factors that influence nurses’ job dissatisfaction. They include: (1) nurse staffing; (2) work and professional practice environments; (3) work relationships; (4) management styles; (5) professional development and career advancement opportunities.Conclusions: Understanding the factors contributing to nurses’ job dissatisfaction is essential in order to identify barriers which may impede the achievement of a Magnet hospital designation.

Herein, we report a case series of HSP that is strictly confined to a street of Zheng village in Xianyang City of Shaanxi Province, northwest of China.
Educating undergraduate general nursing students to conduct Mental State Assessments using high fidelity video simulations that develops learning in the affective domain
Authors: Gardner Andrew , Johns Sherie Donna
Published: September 2018

Nursing students require a range of clinical skills to contribute as part of the mental health care team, we would argue that one of the quintessential skills is the ability to complete and accurately record a Mental State Assessment (MSA). Teaching students how to complete a MSA using high fidelity video simulations (HVFS) prepares them for the reality of clinical practice including cognitive skill development and emotional readiness for clinical practicum in acute mental health care settings. In this study, three HVF simulations were created to facilitate students learning, based on well documented evidence supporting the use of video content as a learning media. However our focus is not only on cognitive skill development in conducting mental state assessments, but in distinguishing the approach to learning in the affective domain. Using this method, students learn to confront and manage their own feelings, beliefs and attitudes and in turn regulate their emotional responses in clinical situations. Pre and post workshop evaluations completed by students for the past three years has resulted in consistently high levels of confidence in ability to conduct a MSA after the workshop. The paired t test was used to calculate the difference between pre and post workshop confidence scores, revealing the two-tailed p value of less than .0001 which is considered to be extremely statistically significant. Therefore, it can be concluded that students completing the 3-day workshop had a significant increase in confidence and competence in performing MSA’s.

Introduction:

Inadequate validation, floor/ceiling effects, and time constraints limit utilization of standardized patient-reported outcome measures. We aimed to validate Patient-reported Outcomes Measurement Information System (PROMIS) computer adaptive tests (CATs) for patients treated surgically for a lumbar disk herniation.

Methods:

PROMIS, CATs, Oswestry Disability Index, and Short Form-12 measures were administered to 78 patients treated with lumbar microdiskectomy for symptomatic disk herniation with radiculopathy.

Results:

PROMIS CATs demonstrated convergent validity with legacy measures; PROMIS scores were moderately to highly correlated with the Oswestry Disability Index and Short Form-12 physical component scores (r = 0.41 and 0.78, respectively). PROMIS CATs demonstrated similar responsiveness to change compared with legacy measures. On average, the PROMIS CATs were completed in 2.3 minutes compared with 5.7 minutes for legacy measures.

Discussion:

The PROMIS CATs demonstrate convergent and known groups' validity and are comparable in responsiveness to legacy measures. These results suggest similar utility and improved efficiency of PROMIS CATs compared with legacy measures.

Levels of Evidence:

Published: September 2018

Nocturnal enuresis (NE) is a combined symptom of nocturia and urinary incontinence. In this review, we aim to summarize the current literature on NE in terms of its definition, diagnosis, and management. Recommended diagnostic evaluation of NE includes a focused history and physical examination, urinalysis, and when indicated, ultrasound examination, flow rate, urine volume chart, urodynamics, and cystoscopy. Therapeutic options include lifestyle modification and medications (i.e., desmopressin and anticholinergics).
Deconstructing the Archetypal Self-Other Dichotomy in William Shakespeare’s The Tempest
Authors: Alqaryouti Marwan Harb , Ismail Hanita Hanim
Published: September 2018

Shakespeare’s The Tempest (1610-1611) is one of the controversial plays regarding whether to be placed in the purview of colonialism or anti-colonialism. The bard sketches two antithetical characters in the course of the play, Prospero and Caliban, who form the two extremes of the self against the other dichotomy. This study aims at proving Shakespeare’s proclaimed presuppositions at the realm of colonialism through his attempt to deconstruct the dichotomic discourse of colonialism via these two characters. The study also explains how the play starts with structuring two binary-oppositional spheres to lead readers eventually to question the very purpose of colonialism, which dehumanizes the colonized people. The data used in this study are generated through both primary and secondary sources of data collection, (i.e. the paly and other studies that give input to the discourse of the study). The paper moreover, focuses on Abdul R. JanMohamad’s concept of Manicheanism allegory to examine the backdrop of postcolonial view of self/other dichotomy. A critical discourse narrative technique is employed in the discussion section of the study based on the deconstruction apparatus, such as binary opposition, Manicheanism allegory and symbolism. The study also refers to Shakespeare’s symbolism of Prospero as a character who can be perceived as Columbus himself, and consequently as the representative of the colonial enterprise. At the end of the play, therefore, the language of Prospero becomes noticeably less hegemonic, as he realizes that the individuals on the island should be emancipated from his dominance. In this way, Prospero becomes the mouthpiece of Shakespeare himself, who conveys counter-colonial beliefs, such as the confusion of the biological and the cultural, and the colonizers’ claim of their superiority, over the colonized; and thus, their right to dominate.
Learning and Retaining Technical Vocabulary with Enhancement Activities in an ESP Course
Authors: Xu Liju
Published: September 2018

The purpose of this paper is to explore the effectiveness of vocabulary enhancement activities on vocabulary learning in an ESP course. In designing the activities, technical terms on journal entries were chosen for the acquisition of language necessary for the successful implementation of accounting major’s professional tasks. The desirable difficulty approach and the four strands principle，focused input, meaning-focused output, language-focused learning and fluency development, were guidelines in combining subject matter and English language learning. To test the result of the activities, the Vocabulary Knowledge Scale was employed to measure students’ knowledge of 50 vocabulary items. Subjects of the ESP course in discussion comprised 200 accounting juniors in Guangdong University of Foreign Studies in China. Half of them in Group A read the texts and did matching exercises and translation exercises. The other half in Group B read the texts and practiced journal entry activity, targeting at accounting concepts and terminologies. The results revealed that Group B gained better results than Group A at a post-test. After the test a reflection on the vocabulary activities was gathered among the participants of Group B. The feedback further proved that the students did benefit from the enhancement activities on selected technical terms.

WPŁYW WYBRANYCH PARAMETRÓW TECHNICZNYCH SYSTEMU NA ODBIÓR FAL RADIOWYCH
Authors: Wilk-Jakubowski Jacek Łukasz
Published: September 2018

Artykuł omawia wpływ wybranych parametrów systemu na odbiór fal radiowych, co ma zastosowanie w optymalizacji systemów łączności. Cel ten realizuje się poprzez dobór parametrów technicznych urządzeń np. współczynnika sprawności anteny odbiorczej. Zwiększenie współczynnika dostępności dla danego systemu wiąże się z minimalizacją wpływu wielu niepożądanych czynników na transmisję fal radiowych (w tym tłumienia podstawowego oraz influencji klimatyczno-atmosferycznej). W rezultacie możliwe staje się zoptymalizowanie istniejących już systemów teletransmisyjnych oraz projektowanie nowych systemów, pozwalających na znaczną poprawę jakości i wiarygodności przekazywanych informacji (zaprezentowane wyniki ograniczą się do częstotliwości z zakresu pasma Ku – powszechnie wykorzystywanego w łączności satelitarnej).
