Published: May 2020

Orientation information of space debris is required to improve the orbital prediction accuracy for mitigation or elimination of a significant threat to not only human space activities but also operational satellites. Obtaining orientation information is currently achievable by applying photometry, adaptive optics (AO) and satellite laser ranging (SLR) technologies. In this study, a new method is proposed based on an echo laser pulse waveform (ELPW) for the orientation determination of space debris; its feasibility was also investigated by numerical simulations. Unlike the photometry and AO technologies available just under the sun-illumination condition and the SLR technology applicable only for cooperative targets, the ELPW is achievable by using a high power laser regardless of the above measurement constraints. A mathematical model is derived to generate the ELPW, and the beam broadening and spreading due to the atmospheric turbulence is taken into account. The Gaussian decomposition based on a genetic algorithm was employed to the ELPWs in order to analyze the orientation features. It is demonstrated from the numerical simulations that the ELPWs have distinctive shapes characterizing the orientation of space debris and therefore our approach was capable of providing orientation information.

Published: May 2020

Professional drivers play a key role in urban road network safety. It is therefore important to employ safer drivers, also find the problem, and train the existing ones. However, a direct driving test may not be very useful solely because of drivers’ consciousness. This study introduces a latent predictor to expect driving behaviors, by finding the relation between taxi drivers’ psychological characteristics and their driving behaviors. A self-report questionnaire was collected from 245 taxi drivers by which their demographic characteristics, psychological characteristics, and driving behaviors were obtained. The psychological characteristics include instrumental attitude, subjective norm, sensation seeking, aggressive mode, conscientiousness, life satisfaction, premeditation, urgency, and selfishness. Driving behaviors questionnaire (DBQ) provides information regarding drivers’ violations, aggressive violations, errors, and lapses. The standard linear regression model is used to determine the relationship between driving behavior and psychological characteristics of drivers. The findings show that social anxiety and selfishness are the best predictors of the violations; aggressive mode is a significant predictor of the aggressive violations; urgency has a perfect impact on the errors; and finally, life satisfaction, sensation seeking, conscientiousness, age, and urgency are the best predictors of the lapses.

Published: May 2020

A vast stream of literature has investigated the effect of corporate social responsibility (CSR) on firms’ financial performance (FFP). However, this effect has remained unclear and undecided. For instance, numerous studies have examined the direct impact of firms’ CSR initiatives on FFP, as well as examining various mechanisms to explain this relationship, but found inconsistent results. The indecisive results indicate that researchers lack consensus to define a mechanism to understand how and under what conditions CSR can affect FFP. Thus, this research aims to investigate how firms’ CSR perception and disclosure derive accounting- (return on equity: ROE, earnings per share: EPS), market- (Tobin Q) and perception-based firms’ financial performance through the mediation of competitive advantage and boundary conditions of family ownership and CEO narcissism. This research underpins the theoretical lens of the resource-based view to derive hypotheses. The research design employed in this study is quantitative, and the approach to theory development is deductive. Multi-method and multi-source data with temporal breaks are collected from 60 manufacturing firms listed on the Pakistan Stock Exchange (PSE). Primary data are collected from the top and middle managers, while secondary data are collected from the annual reports published by these firms. This research found that competitive advantage significantly mediated the indirect impact of perceived CSR and disclosure on FFP. Further, this relationship is strengthened by the contingencies of family ownership and CEO narcissism. Our results will assist the management of the firms to understand the implications of CSR perceptions and disclosure to derive a competitive advantage that ultimately translates into the firms’ financial performance. Further, this research also revealed that managers should concentrate on the boundary conditions of family ownership and CEO narcissism as well. In particular, this research contributes to understand why CSR is viewed to have a strategic importance for the firms and how a resource-based perspective might be utilized in such endeavors.

Authors: Gao Zhicheng , Wan Rongjin , Ye Qian , Fan Weiguo , Guo Shihui , Ulgiati Sergio , Dong Xiaobin
Published: May 2020

Typhoons and cyclones are the most impacting and destructive natural disasters in the world. To address the shortcomings of a previous typhoon disaster risk assessment (for example, human factors were involved in determining weights by importance, and this affected the experimental results), an emergy method, which converts energy flows of different properties into the same solar energy basis for a convenient comparison, was used to assess the risk of regional typhoon disasters. Typhoon disaster-related data from 2017 were used to develop an index system including resilience, potential strength, and sensitivity which was in turn applied to assess typhoon disaster risks in Zhuhai City, Guangdong Province, China. The results showed that the spatial distribution of the typhoon disaster risks in Zhuhai significantly differed, with the highest risk in Xiangzhou district, the second highest risk in Doumen district, and the lowest risk in Jinwan district. In addition, improving the level of regional resilience can effectively reduce risks from typhoon disasters. The application of the emergy method in a typhoon disaster risk assessment may provide some theoretical support for national and regional governmental strategies for disaster prevention and reduction.
Nature-Related Cognitive Schemas and Self-Reported Psychological Flourishing
Authors: Diržytė Aistė , Perminas Aidas
Published: May 2020

Some sustainability-related belief systems (or schemas in Cognitive Behavior Therapy) might result in shame, guilt, or denial if a person fails to meet the standards. The psychology of Harmonization relates sustainability to flourishing but not to human misery and delineates flourishing one’s own life. What nature-related cognitive schemas coexist with psychological flourishing? The purpose of this study was to identify the nature-related cognitive schemas that correlate to self-reported psychological flourishing. This paper provides some data on an overall survey (n = 722) that aimed at evaluating the cognitive schemas, strengths, and cognitive abilities of Lithuanian gymnasium students. We applied the Flourishing Scale (FS) of E. Diener alongside several measures to investigate nature-related cognitive/emotional/behavioral variables. The results revealed associations between different nature-related cognitive schemas (experiential, consumeristic, eco-protectionist, and valorist) and psychological flourishing, positive emotional reactions to nature, and spending time in nature. As this study demonstrates only positive or negative relationships among the examined variables, one of the implications for future research is identifying schemas as predictors of behavioral sustainability and creating an experimental or longitudinal design.
Ecological Stoichiometry Homeostasis of Six Microelements in Leymus chinensis Growing in Soda Saline-Alkali Soil
Authors: Li Yuefen , Gong Heyang , Li Shujie , Zhang Yushu
Published: May 2020

Soil salinization poses severe threats to grassland ecosystems in various parts of the world, including the Songnen Plain in northeast China. Severe impairment of plant growth in this soil is generally attributed to high soil pH, total alkalinity, and sodium (Na) contents. This paper focuses on the ecological stoichiometry of microelements, which has received much less attention than relations of macroelements, in the soil and plants (specifically Leymus chinensis) growing in it. The results show that the soil’s manganese (Mn), zinc (Zn), iron (Fe), copper (Cu), nickel (Ni) and molybdenum (Mo) contents are lower than average in Chinese soils, but only Mn and Zn are severely deficient in L. chinensis. With increases in soil pH, total alkalinity, and Na, the Mo contents in both soil and L. chinensis slightly increase, while contents of the other microelements decline. Homeostasis indices obtained for the six microelements—and Fe/Zn, Fe/Ni, Fe/Cu, and Cu/Zn ratios—were all between 0.82 and 3.34 (ranging from just below the “plastic” threshold to “weakly homeostatic”). Despite Zn deficiency in the soil, Zn appears to have the highest homeostasis of the six elements in L. chinensis (homeostasis indices of Zn, Cu, Ni, Mn, Fe and Mo were 3.34, 2.54, 1.86, 1.76, 1.52, and 1.33, respectively). In addition, the Cu/Zn ratio had the highest homeostasis index (1.85), followed by Fe/Zn (1.02), Fe/Cu (0.95) and Fe/Ni (0.82). Appropriate application of Mn and Zn fertilizers is recommended to promote the growth and development of L. chinensis in soda saline-alkali soil.

Published: May 2020

The economic crisis of 2008 strongly affected European countries, many of them slipping into a recession whose depth and manifestation differed substantially from country to country and from region to region. In this context, economists revived the concept of economic resilience of states and regions and focused on identifying and explaining its determinants. The literature investigates ways to enhance economic resilience through appropriate public policies, but the studies conducted so far have several limitations. In order to contribute to this goal, this article analyzes the economic resilience of the regions of seven Eastern European countries (Bulgaria, Hungary, Croatia, Czech Republic, Romania, Slovakia and Slovenia) and its main determinant factors. The results show that, in terms of resistance, Bulgaria, Slovenia and their regions behaved best, while Croatia, Czech Republic, Hungary, Romania and Slovakia (including regions) had a negative evolution. In terms of recovery Bulgaria (and 4 regions out of 6), Romania (5 out of 8 regions) and Slovakia (4 of 4 regions) performed better than the other Eastern countries. The determining factors of resilience for the studied regions concern the size of the manufacturing sector, the services and public administration, entrepreneurship and the human capital represented by tertiary education; agriculture and urban population have no significant influence on regional resilience. We adopt an econometric approach in this study, using the quantile regression for the analysis. Based on these empirical evidences, appropriate proposals have been formulated, useful to both field theorists and practitioners in public policy.
From Religious Belief to Intangible Cultural Heritage Tourism: A Case Study of Mazu Belief
Authors: Yao Dan , Zhang Ke , Wang Lin , Law Rob , Zhang Mu
Published: May 2020

Mazu belief was recognized by United Nations Educational, Scientific and Cultural Organization (UNESCO) as the Intangible cultural heritage of Humanity in 2009, which is China’s first world-class folklore intangible cultural heritage. More than 5000 Mazu temples and 200 million tourists who believe in Mazu can be found worldwide. The aim of the study was to take Meizhou Island as a case study to understand the relationships among tourists’ perceived value, place attachment, and revisit intention. In total, 424 tourists in Meizhou Island were surveyed and structural equation modeling was performed to test such relationships. Results show that tourists’ perceived value has a significant positive impact on place attachment (p < 0.05), which in turn has a significant positive impact on revisit intention (p < 0.05). The results of bootstrap test show that the confidence intervals are (0.001, 0.328), (0.147, 0.425), (0.058, 0.396), (0.092, 0.408), respectively, which do not contain 0. Therefore, place attachment acts as a complete intermediary in the relationship between tourism resources and service value, social value, cost value, and revisit intention. The confidence interval of the direct effect of cultural value and revisit intention is (0.193, 0.501), which does not contain 0, indicating that place attachment acts as a partial mediator in the relationship between cultural value and revisit intention. Findings of this study would be of use to readers of cultural tourism.
Biodegradation of Bioplastic Using Anaerobic Digestion at Retention Time as per Industrial Biogas Plant and International Norms
Authors: Shrestha Ankita , van-Eerten Jansen Mieke C. A. A. , Acharya Bishnu
Published: May 2020

Bioplastics are gaining interest as an alternative to fossil-based plastics. In addition, biodegradable bioplastics may yield biogas after their use, giving an additional benefit. However, the biodegradability time in international norms (35 days) far exceeds processing times in anaerobic digestion facilities (21 days). As the bioplastic packaging does not indicate the actual biodegradability, it is important to understand the time required to biodegrade bioplastic if it ends up in the anaerobic digestion facility along with other organic waste. For this work, cellulose bioplastic film and polylactic acid (PLA) coffee capsules were digested anaerobically at 55 ℃ for 21 days and 35 days, which are the retention times for industrial digestors and as set by international norms, respectively. Different sizes of bioplastics were examined for this work. Bioplastic film produced more biogas than bioplastic coffee capsules. The biodegradability of bioplastic was calculated based on theoretical biogas production. With an increase in retention time, biogas production, as well as biodegradability of bioplastic, increased. The biodegradability was less than 50% at the end of 35 days for both bioplastics, suggesting that complete degradation was not achieved, and thus, the bioplastic would not be suitable for use in biogas digesters currently in use.

Published: May 2020

Faced with increasing conflicts between economic and environmental development, it is extremely urgent to promote the green growth of enterprises. As an incentive environmental regulation measure, an environmental tax has been proven to effectively alleviate environmental problems and reduce corporate pollutant emissions. From the perspective of environmental tax equity and efficiency, this study collects more than 100,000 enterprises’ pollutant-discharge and pollutant-discharge fee data from 4300 pollutant disposal enterprises in Yunnan Province, China in 2017. The study analyzes the marginal abatement cost (MAC) of water pollution and air pollution in key industries by using the MAC accounting method. Under the three scenarios of low, medium and high tax rates set by the study, the study evaluates the applicable tax rates of environmental tax of enterprises under different tax rates. The main findings of the study are: (1) the MAC of pollutants in various industries is quite different in different industries; (2) the environmental tax rate of 2018 is generally low and is not enough to encourage enterprises to reduce more pollution; (3) most enterprises will not invest a large amount of funds to carry out technological transformation for green production, without the government’s mandatory environmental regulation measure. The study recommends that the government needs to increase the environmental tax rate, gradually approach the cost of corporate pollutant-treatment and force the technological transformation of enterprises. At the same time, the government itself needs to do a good job of tax neutrality, increase the compensation for environmental protection behaviors of enterprises, and encourage green development of enterprises. Finally, the taxation supervision should be strengthened, and the tax violations of enterprises should be checked strictly for avoidance of tax cuts against rules.

Published: May 2020

As the number of aged infrastructures increases every year, a systematic and effective asset management strategy is required. One of the most common analysis methods for preparing an asset management strategy is life cycle cost analysis (LCCA). Most LCCA-related studies have focused on traffic and energy; however, few studies have focused on school buildings. Therefore, an approach should be developed to increase the investment efficiency for the performance improvement of school buildings. Planning and securing budgets for the performance improvement of school building is a complex task that involves various factors, such as current conditions, deterioration behavior and maintenance effect. Therefore, this study proposes a system dynamics (SD) model for the performance improvement of school buildings by using the SD method. In this study, an SD model is used to support efficient decision-making through policy effect analysis, from a macro-perspective, for the performance improvement of school buildings.
Does High-Speed Railway Influence Convergence of Urban-Rural Income Gap in China?
Authors: Li Weidong , Wang Xuefang , Hilmola Olli-Pekka
Published: May 2020

Transportation is an important factor affecting the balance of regional economic pattern. The construction of high-speed railway enhances the mobility of population, capital, technology and information resources between urban and rural areas. Will it further affect the income gap between urban and rural areas? Based on the nonlinear time-varying factor model, this paper analyzes the convergence of urban-rural income gap with the angle of high-speed railway. After rejecting the assumption of overall convergence in the traditional four economic regions, three convergence clubs of urban-rural income gap were found. For these ordered logit regression model is used to explore the initial factors that may affect the formation of “convergence club”. Empirical results show that the construction of High-speed railway has effectively narrows the urban-rural income gap in China, but it is not the cause of the formation of the three convergence clubs. The convergence effect of High-speed railway on the urban-rural income gap in China is still relatively weak.
Investigating the Factors Influencing Pedestrian–Vehicle Crashes by Age Group in Seoul, South Korea: A Hierarchical Model
Authors: Park Seunghoon , Ko Dongwon
Published: May 2020

Walking is the most natural form of moving in everyday life. However, the urban environment is not always safe for walking. Hence, it is appropriate to create pedestrian safety-oriented neighborhood environments to promote walkability. This study identifies factors that can affect the severity of pedestrian injuries by considering and comparing the individual characteristics of pedestrian crashes and the built environment of neighborhoods using a hierarchical model. The main results of this study are as follows. Those under 18 and over 65 years of age, which are recognized as vulnerable road users, are more affected by the neighborhood environments than other age groups. Parks, convenience stores, and restaurants are likely to play a significant role in reducing the severity of pedestrian injuries. However, for pedestrians under 18 years of age, convenience stores that students often visit after school are likely to increase the severity of pedestrian injuries. The severity of pedestrian injuries is likely to be lower at non-signalized crosswalks and intersections than at signalized crosswalks and intersections. The study is expected to contribute to existing literature on the topic and guide policy makers and planners to arrive at consensus approaches when making decisions on how to build pedestrian safety-oriented neighborhoods.
Pesticide–Virus Interactions in Honey Bees: Challenges and Opportunities for Understanding Drivers of Bee Declines
Authors: Harwood Gyan P. , Dolezal Adam G.
Published: May 2020

Honey bees are key agricultural pollinators, but beekeepers continually suffer high annual colony losses owing to a number of environmental stressors, including inadequate nutrition, pressures from parasites and pathogens, and exposure to a wide variety of pesticides. In this review, we examine how two such stressors, pesticides and viruses, may interact in additive or synergistic ways to affect honey bee health. Despite what appears to be a straightforward comparison, there is a dearth of studies examining this issue likely owing to the complexity of such interactions. Such complexities include the wide array of pesticide chemical classes with different modes of actions, the coupling of many bee viruses with ectoparasitic Varroa mites, and the intricate social structure of honey bee colonies. Together, these issues pose a challenge to researchers examining the effects pesticide-virus interactions at both the individual and colony level.

Published: May 2020

El trabajo se realizó en la finca experimental de El Coco perteneciente al Subcentro Pacífico Marciaga del IDIAP, distrito de Penonomé, provincia de Coclé, sobre un suelo clasificado en la familia fino, mezclado, isohipertérmico, Aeric Tropaquept. El clima del sitio se caracteriza por ser tropical húmedo, con promedio de 1,480 mm de precipitación al año, con una temperatura promedio que oscila entre 20 y 35ºC. Se evaluaron 4 niveles de Urea (0, 30, 60 y 100kgN/ha) y 2 niveles de KCl (0 y 40kgK2O/ha) en el cultivo de arroz bajo riego con 3 réplicas en Llanos de Coclé en Panamá. La siembra se realizó al voleo y la cantidad fue de 113kg/ha de semilla (La Variedad: IDIAP145-05), ajustada de acuerdo el porcentaje de germinación. De los resultados de análisis de varianza, se observó diferencia significativa al 1% no sólo en los niveles de N sino también en los de K sobre rendimiento del grano. Se aumentó hasta 3779 kg ha-1 como el rendimiento por la aplicación de 100 kgN ha-1 y de 40kg K2O ha-1. Se considera que la aplicación óptima-económica de N y K fue muy importante para asegurar el rendimiento adecuado para el cultivo de arroz bajo riego en la región de Llanos de Coclé en Panamá. Por otra parte, en el experimento, se observó diferencia significativa al 5% sobre la absorción de Fe en la planta en los tratamientos de K. Se esperará prevenir la absorción elevada de este elemento y Bronzeamiento en la planta de arroz bajo riego. En realidad, por presencia de Cl- (Electrodo potencial estándar: E0=1.46V), el Fe2+ se convertiría al Fe3+ (Electrodo potencial estándar: E0=0.77V). Por eso, se considera que hay dos efectos no sólo para abono potásico como nutrimento en el cultivo de arroz sino también para oxidación del hierro como mejoramiento química del suelo.

Evaluation of Useful Biomechanical Parameters On Scoliosis Using Finite Element Method
Authors: Khademi Midiya , Nikoo Ali
Published: May 2020

Background: Scoliosis is a deformity of the vertebral column, and shape-changing and deformation of the spine are some critical factors that can cause this abnormality. This condition causes some problems like deflection of the spine in the coronal plane toward medial or lateral. Cobb angle is a measurement for the investigation of the severity of this condition. There are several effective therapies suggested for the reduction of the Cobb angle for patients who has this abnormality. It has suggested that before applying external forces to correct this condition, biomechanical evaluation of this deformity, can be useful during diagnosis. Methods: The purpose of this study is the evaluation of Cobb angle correction using external forces. For this aim first, the dimensional data of the patient’s vertebrae are extracted from CT-scan images using Mimics software, and the vertebral column modeled in Catia software for finite element analysis (FEA). Afterward, the model was imported into Abaqus software to evaluate the effect of forces on the spine model. The study was done by assuming two cases for the spine, one-piece (without a nucleus) and two-piece (with a nucleus) intervertebral disc. Results: After studying the results of this simulation, it concluded that after applying gravity force to these two cases, the percentage of Cobb angle’s reduction was about 0.05 for a two-piece disc and about -0.18 for the one-piece disc. Therefore, the two-piece disc assumption was better for analyzing this parameter. The results of maximum displacement and von misses stress show that the two-piece disc is accurate. Conclusion: In order to investigate which analysis is appropriate to be selected, choosing a twopiece intervertebral disc model is superlative. Whether our goal is only to examine the stress which is present in the patient model, choosing a one-piece disc is a more optimal duo to take much less time.

Published: May 2020

Coronaviruses are a large family of viruses that can cause a variety of diseases in humans. Some coronaviruses cause only mild illnesses like the common cold. While, some coronaviruses such as SARS-CoV (SARS-associated coronavirus) and Middle East respiratory syndrome coronavirus (MERS-CoV) have, in recent years, been able to cause severe respiratory involvement (pneumonia), leading to death in several patients. By identifying the genomic sequence of the new human coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) it has been revealed that it belongs to the beta coronavirus genus. COVID-19 appears to be transmitted by a mechanism similar to the influenza virus via person to person, sneezing coughing, or contact with the secretions of infected patients. Early symptoms of these respiratory viruses include fever, cough, and shortness of breath, with an incubation period of 2-14 days. SARS-CoV-2 is an acute respiratory disease that initially causes lung damage. SARS-CoV-2 can affect other organs, including the kidneys. Kidney damage may be caused by alterations that occur during coronavirus infection. It seems that low-oxygen delivery to tissues like the kidney in the setting of this disease may lead to ischemic damage of the kidney. Considering the importance of the kidneys, as one, this review study aimed to investigate the effect of the new coronavirus on the kidneys and its role in the development of renal failure.

Published: May 2020

Introduction: The concept of diabetic nephropathy, as a metabolic disease, is now being replaced by chronic low-grade inflammatory disease. Tumor necrosis factor alpha (TNF-α) is a proinflammatory cytokine that plays an important role in the pathogenesis and clinical outcomes of diabetic nephropathy. Objectives: This study aimed to determine the relationship between plasma and urinary levels of TNF-α and chronic kidney disease (CKD) in patients with type 2 diabetes mellitus. Patients and Methods: In this descriptive-analytical study, patients with type 2 diabetes mellitus who referred to the endocrine clinic in Kashan (2016) were enrolled in the study and their clinical and laboratory data were recorded. Albumin/creatinine ratio (ACR) and glomerular filtration rate (GFR) were calculated. The patients were divided into three groups based on their GFR. Serum and urinary levels of TNF-α were determined by ELISA and were compared between the studied groups. Results: A total of 128 patients were evaluated. Of all, 35 patients (27.3%), 39 patients (30.4%), and 54 patients (42.3%), respectively, were suffering from stage 1, stage 2, and stage 3 CKD. The plasma levels of TNF-α in patients with stage 1, 2, and 3 CKD, were 66.20 ± 33.27 pg/mL, 67.47 ± 42.98 pg/mL, and 77.32 ± 47.23 pg/mL respectively, since the difference among them was not significant (P= 0.417). In addition, the urinary levels of TNF-α in patients with stage 1, 2, and 3 CKD, respectively, were 88.18 ± 26.66 pg/mL, 97.41 ± 57.76 pg/mL, and 101.18 ± 60.47 pg/mL, since no significant difference was observed between the three groups (P=0.957). Conclusion: Based on the results of this study, with changing the stage of CKD, the serum and urinary levels of the TNF-α increases too, although this increase is not significant. Moreover, the plasma and urinary levels of the TNF-α have a direct and significant relationship with each other. It is recommended to conduct further studies in this field.

Background: Human error is one of the major causes of accidents in the petrochemical industry. Under critical situation, human error is affected by complex factors. Managing such a situation is important to prevent losses and injury. This study aimed to develop a dynamic model of human error assessment in emergencies in the petrochemical industry. Study design: A cross-sectional study. Methods: Fuzzy Bayesian network was used to improve the capabilities of the method for determining the control mode. Fuzzy-AHP-TOPSIS method was also used to prioritize emergency scenarios and human error assessment was applied for the most important emergency condition. Results: Fire in a chemical storage unit was recognized as the most important emergency condition. Common Performance Conditions (CPCs) were determined based on the opinions of a panel of 30 experts and specialists and 7 CPCs were selected for emergencies; then, based on the results of AHP method the relative weights were determined. Finally, membership functions, inputs, and outputs of fuzzy sets, CPC values in 8 emergency response tasks, and the probability of control modes were determined using Bayesian Cognitive Reliability and Error Analysis Method (CREAM) method. Conclusion: This method could be applied to overcome the weaknesses of traditional methods, provide a repeatable method for human error assessment, and manage human error in an emergency.
Qaanaaq 2001: mineral exploration reconnaissance in North-West Greenland
Authors: Thomassen Bjørn , Dawes Peter R. , Steenfelt Agnete , Krebs Johan Ditlev
Published: May 2020

Project Qaanaaq 2001, involving one season’s field work, was set up to investigate the mineral occurrences and potential of North-West Greenland between Olrik Fjord and Kap Alexander (77°10´N – 78°10´N; Fig. 1). Organised by the Geological Survey of Denmark and Greenland (GEUS) and the Bureau of Minerals and Petroleum (BMP), Government of Greenland, the project is mainly funded by the latter and has the overall goal of attracting the interest of the mining industry to the region. The investigated region – herein referred to as the Qaanaaq region – comprises 4300 km2 of ice-free land centred on Qaanaaq, the administrative capital of Qaanaap (Thule) municipality. Much of the region is characterised by a 500–800 m high plateau capped by local ice caps and intersected by fjords and glaciers. High dissected terrain occurs in Northumberland Ø and in the hinterland of Prudhoe Land where nunataks are common along the margin of the Inland Ice.

Enhanced tide model: Improving tidal predictions with integration of wind data
Authors: Huff Thomas , Feagin Rusty , Figlus Jens
Published: May 2020

Publicly available tidal predictions for coastlines are predominantly based on astronomical predictions. In shallow water basins, however, water levels can deviate from these predictions by a factor of two or more due to wind-induced fluctuations from non-regional storms. To model and correct these wind-induced tidal deviations, a two-stage empirical model was created: the Enhanced Tidal Model (ETM). For any given NOAA tide gauge location, this model first measured the wind-induced deviation based on a compiled dataset, and then adjusted the astronomical predictions into the future to create a 144-hour forecast. The ETM, when incorporating wind data, had only 76% of the error of NOAA astronomical tidal predictions (e.g. if NOAA had 1.0 ft. of error, ETM had only 0.76 ft. error from the observed water level). Certain ETM locations had approximately half (49%) as much prediction error as NOAA. With the improvement in tidal accuracy prediction, the ETM has the ability to significantly aid in navigation along with coastal flood prediction. We envision the ETM as a resource for industry and the public to make informed decisions that impact their livelihood.

Sigurðr, Þórr and Ragnarök and their Christian Counterparts
Authors: Braithwaite-Westoby Manu
Published: May 2020

Few scholars would deny that some Old Norse myths have Christian counterparts, a phenomenon first noticed by nineteenth-century archaeologists and antiquarians in their observations of Anglo-Scandinavian stone sculpture in northern England. It is strange, therefore, that despite this long tradition, there is no systematic study on the topic. While this ambition is unfortunately outside the scope of this article, it does seek to address a number of Old Norse myths/legends and place them in conjunction with their Christian counterparts. One of the most important myths for Anglo-Scandinavian craftsmen was probably Sigurðr, who has an obvious parallel in Christ. The apocalyptic narrative in Voluspa known as Ragnarök was also a very popular subject and has a clear cognate in the apocalyptic sections of the Bible. Þórr and the Miðgarðsormr, though less appealing to artists, strongly recalls accounts of the conflict between Christ and Satan or Leviathan. This article uses a theoretical methodology called ‘figural interpretation’ to examine the Old Norse myths and explore how they reflect certain myths from the new religion. While distinctly art historical in approach, this article also invokes some Old Norse texts where relevant, which may themselves have been influenced by Christian thinking.
La Asociación General de Estudiantes Latinoamericanos: un espacio de formación de la juventud en París
Authors: Graterol Acevedo Gloria Lisbeth
Published: May 2020

La Asociación General de Estudiantes Latinoamericanos (AGELA) fue creada en el año 1925 bajo el afán de la unidad latinoamericana y con una postura antiimperialista. Esta asociación, construida dentro de un contexto europeo, veló por la defensa de los estudiantes de América Latina que se encontraban en la Universidad de la Sorbona en París y, a su vez, les permitió posicionar su perspectiva crítica sobre la realidad de su región. El objetivo de este artículo es resaltar el rol del activismo académico de estos jóvenes latinoamericanos y las relaciones que a partir del mismo construyeron. Asimismo, se destaca el cómo esta asociación les permitió promover el ideal unionista y antiimperialista propio de su contexto intelectual latinoamericano.
La juventud argentina durante la Segunda Guerra Mundial. Una mirada desde periódicos nacionalistas
Authors: Monacci Laura
Published: May 2020

La Segunda Guerra Mundial se caracterizó por ser un enfrentamiento en que primó el aspecto ideológico a la hora de conformar los bandos que se enfrentaron así como de construir al enemigo. Esto condujo a que adoptara características propias de choque en el plano internacional tanto como dentro de las fronteras de un mismo país afectando a la totalidad de la población, que se vio de una u otra manera involucrada, confrontando -cuando no directamente en el frente de batalla- por la familia ideológica que defendían.Argentina no estuvo exenta de dicho enfrentamiento ideológico, del que tomó partido gran parte de la sociedad y en que participó activamente un grupo que fue cobrando mayor visibilidad desde comienzos del siglo XX y a medida que la postura por un bando u otro se radicalizaba. Este grupo estaba compuesto por los jóvenes, que hacían sentir su voz en la arena política local, representando a sus movimientos y confrontando de igual a igual con sectores de la política anteriormente detentados exclusivamente por sus mayores.Este trabajo pretende brindar luz sobre este colectivo heterogéneo en un periodo en que la juventud no siempre fue interpretada como un actor social autónomo.

Authors: Rubio García Gonzálo
Published: May 2020

A lo largo del siglo XX, varias naciones reformaron sus escritos constitucionalesdecimonónicos con el propósito de ampliar los derechos de los ciudadanos e incorporar regulaciones económico-sociales. La reforma de la Constitución se instauró en la Argentina hacia el año 1949 en un contexto de gran polarización política. En este artículo buscaremos exponer los diferentes argumentos que mostraron los intelectuales y políticos peronistas para defender la iniciativa reformista, teniendo en cuenta, además, las diferentes cosmovisiones queesbozaron y las influencias de otros intelectuales que recibieron los senadores y diputados.
