Pyramid Inter-Attention for High Dynamic Range Imaging
Authors: Choi Sungil , Cho Jaehoon , Song Wonil , Choe Jihwan , Yoo Jisung , Sohn Kwanghoon
Published: September 2020

This paper proposes a novel approach to high-dynamic-range (HDR) imaging of dynamic scenes to eliminate ghosting artifacts in HDR images when in the presence of severe misalignment (large object or camera motion) in input low-dynamic-range (LDR) images. Recent non-flow-based methods suffer from ghosting artifacts in the presence of large object motion. Flow-based methods face the same issue since their optical flow algorithms yield huge alignment errors. To eliminate ghosting artifacts, we propose a simple yet effective alignment network for solving the misalignment. The proposed pyramid inter-attention module (PIAM) performs alignment of LDR features by leveraging inter-attention maps. Additionally, to boost the representation of aligned features in the merging process, we propose a dual excitation block (DEB) that recalibrates each feature both spatially and channel-wise. Exhaustive experimental results demonstrate the effectiveness of the proposed PIAM and DEB, achieving state-of-the-art performance in terms of producing ghost-free HDR images.
The UnMOOCing Process: Extending the Impact of MOOC Educational Resources as OERs
Authors: Ruipérez-Valiente José A. , Martin Sergio , Reich Justin , Castro Manuel
Published: September 2020

Massive Open Online Courses (MOOCs) came into the educational ecosystem attracting the attention of the public media, businesses, teachers, and learners from all over the world. The original courses were completely open and free, targeting the worldwide population. However, current MOOC providers have pivoted towards more private directions, and we often find that MOOC materials are completely closed within their hosting platforms and cannot be retrieved from them by their learners. This diminishes the potential of MOOCs by making content available to a small proportion of learners and severely limits the reusability of the educational resources. In this paper, we present a process that we call ‘unMOOCing’, in which we transform the resources of a MOOC into OERs. We taught a MOOC on Open Education in the UNED Abierta platform, and we ‘unMOOCed’ all of its educational resources, making them available to download by the learners that are taking the course. The results of the unMOOCing were very encouraging: the possibility of downloading the course resources was the most highly rated component of the course. Additionally, the two unMOOCed materials that were considered as most useful (presentations and contents in a PDF) were downloaded by 90% of the learners. Now that the majority of MOOC providers are moving towards a more closed educational approach, we believe that this paper sends a powerful message for bringing back the original MOOC concept of ‘Openness’ with the unMOOCing process, thus contributing to the wider dissemination and democratization of education across the globe.
Mapping the Knowledge Base of Sustainable Supply Chain Management: A Bibliometric Literature Review
Authors: Nimsai Suthep , Yoopetch Chanin , Lai Polin
Published: September 2020

Supply chain management (SCM) concerns itself with the integration of a firm’s internal management processes with the external environment. This could explain why sustainability has been embraced by scholars who study SCM. This bibliometric review was untaken with the explicit goals of updating and extending prior reviews of research on sustainable SCM (S-SCM). The goals of this research were to document the scope and development of S-SCM research; identify influential journals, authors, and documents; analyze the intellectual structure of this field of sustainability inquiry, and highlight emerging topics on the frontier of S-SCM inquiry. By using bibliometric tools, a relatively large and rapidly growing corpus of peer-reviewed research documents concerned with S-SCM were found. Citation analyses of journals, authors, and documents yielded a surprisingly high level of scholarly content for a literature body of such recent vintage. The author co-citation analysis revealed three coherent but closely connected groups of thought that comprise the intellectual structure of this knowledge base. Finally, the analysis identified a constellation of topics concerned with the integration of internal processes (e.g., decision-making, manufacturing, sensitivity analysis, risk assessment, life-cycle assessment) and the organizational environment (e.g., climate change, gas emissions, carbon emissions, greenhouse gases, energy utilization, climate change). The results of this research concluded that SCM practitioners and scholars may have embraced sustainability more than any other field of management.
Can We Understand Non-Tourism as a Form of Sustainable Tourism? The Role of Lifestyle and Motivations behind Non-Traveling Based on the Hungarian Example
Authors: Dávid Lóránt Dénes , Csapó János , Nagy Ákos , Törőcsik Mária
Published: September 2020

This paper aims to study non-travelers in order to try to understand why they are absent from tourism and what the causes are for their decision. Our research showed that the study of postmodern causes apart from classic ones holds unique potential in the research of sustainable tourism processes as well. The results of cross-tabulation and correspondence analysis show that postmodern and classic causes are tightly connected to lifestyle, which represents the central theme of the current study based on the results of a Hungarian representative online survey. A certain limitation is that our research is based on the case of Hungary; however, the introduced methodology can be used in general for identifying and evaluating non-travelers. As research implications, the authors believe that the methodology and results can be used by the actors of the tourism supply market and by decision makers as well, especially for segmenting purposes. If we understand who the non-tourists or non-travelers are, we can, on the one hand, determine the latent tourism potential of a tourism destination; on the other hand, we can also receive information on specific market segments, which could contribute to sustainable tourism mostly because of the postmodern causes for non-traveling.
An Ecological Perspective on University Students’ Sustainable Language Learning during the Transition from High School to University in China
Authors: Li Chen , Abrar-ul-Hassan Shahid , Gao Fei
Published: September 2020

Transitioning from high school to university presents a significant challenge for many students on multiple fronts, including language learning. This mixed-method study draws on an ecological perspective to investigate students’ English learning experiences during the transition from high school to university in China, focusing on teaching content, teaching approach, assessment and feedback, and self-regulated learning. Data is collected from six universities at three different academic levels in China, and analyzed using both statistical and thematic analysis. The research finds that there are differences between high school and university English language education in the above-mentioned four areas, and students’ ecopotentials are of critical importance for their adaptation to university English learning. These findings suggest the necessity of the continuity of teaching content, the promotion of individualized curricula, and the cultivation of self-regulated learning capacities to support students’ sustainable English learning during the transition from high school to university.

Authors: Alves Fernando , Cruz Sara , Ribeiro Anabela , Bastos Silva Ana , Martins João , Cunha Inês
Published: September 2020

Nowadays, the elderly tend to make more trips: Health benefits resulting from their daily walking routines are an important topic in the context of urban renewal processes. Many health organizations and researchers have demonstrated the influence of the urban environment on walkability levels. This article aims to design a multifactor Walkability Index for Elderly Health (WIEH), capable of associating both the adequacy level of public spaces to elderly walkability, and physical exercise benefits while walking. The methodological approach comprised two main parts: Firstly, a literature review of main reports, legislation, and scientific articles was conducted at the intersection of ‘gerontology and physical exercise’ with ‘urban design and mobility’, leading to the selection of four aging-related studies as main contributors to the design of the WIEH; and, secondly, the development of the WIEH was undertaken, based on two premises and designed according to four steps. The first premise defined three systematic areas (urban tissue, urban scene, and safety), variables, and criteria to classify the pedestrian network; and the second premise focused on slopes and stairs in public spaces. The WIEH is divided in four steps: (1) Analyzing public spaces and characterizing their quality for walking, (2) considering the existence of slopes and stairs, (3) calculating different routes for the elderly in their daily routines, or when going to points of interest, and (4) selecting the “heart-friendly route” for elderly people. Adequate walking paths for the elderly can be identified through this innovative approach, with the aim of achieving direct health benefits during their daily routines. Ultimately, the WIEH is capable of supporting decision makers and designers in creating inclusive and age-friendly spaces.
COVID-19 and Disruption in Management and Education Academics: Bibliometric Mapping and Analysis
Authors: Rodrigues Margarida , Franco Mário , Silva Rui
Published: September 2020

COVID-19, What to do now? This issue has had devastating effects in all domains of society worldwide. Lockdowns, the lack of freedom and social distancing meant the closure of a country’s entire activity. Having effects at all levels, beside incalculable ones in health, it is argued that scientific activity in education, business, economics and management suffered some of the most drastic impacts of this pandemic. This study aims to map the scientific literature in these areas in the context of COVID-19 and analyze its content through bibliometrics, which made it possible to highlight the scarcity of studies on the topic, namely empirical studies on the effects of this pandemic on scientific research and teaching/education. The results show there is a lack of peer-reviewed publications on this topic, with the studies covered (93) via the threads used revealing only 28 articles coming within the proposed objective. The bibliometrics corroborates that shortage. Finally, the contributions and implications for theory and practice are presented, followed by the limitations and suggestions for future research.
Overexpression of Citrate Synthase Increases Isocitric Acid Biosynthesis in the Yeast Yarrowia lipolytica
Authors: Hapeta Piotr , Rakicka-Pustułka Magdalena , Juszczyk Piotr , Robak Małgorzata , Rymowicz Waldemar , Lazar Zbigniew
Published: September 2020

Yarrowia lipolytica is a non-conventional yeast producing valuable compounds, such as citric acids, from renewable raw materials. This study investigated the impact of citrate synthase overexpression on the biosynthesis of citric and isocitric acid in Y. lipolytica. Two transformants of Y. lipolytica A101.1.31 strain (efficient citric acid producer), overexpressing CIT1 or CIT2 gene (encoding proteins with citrate synthase activity), were constructed. The results revealed that overexpression of either of these genes enhances citrate synthase activity. Additionally, the cit1 knockout strain was unable to use propionate as the sole carbon source, which proves that CIT1 gene encodes a dual activity protein–citrate and 2-methylcitrate synthase. In the overexpressing mutants, a significant increase in isocitric acid biosynthesis was observed. Both CIT1 and CIT2 overexpressing strains produced citric and isocitric acid from vegetable oil in a ratio close to 1 (CA/ICA ratio for wild-type strain was 4.12).
Enhancement of Mutual Recognition and Mobility of BIM Experts in ASEAN Countries
Authors: Dao Thuy-Ninh , Chen Po-Han , Nguyen The-Quan
Published: September 2020

The Association of Southeast Asian Nations (ASEAN) was established in 1967 to promote the integration and creation of new opportunities for citizens of ASEAN member countries. ASEAN member countries have signed mutual recognition agreements on services (including services in the construction industry) since 2005 to facilitate the movement of human resources in ASEAN countries, with engineering services qualifications being one of the eight professional qualification recognition schemes in the region. In particular, a recent trend in the construction industry is the use of building information modeling (BIM). While BIM practitioners are increasing, BIM Practitioner Certifications (BPCs) have not yet been legalized and recognized. This study conducted interviews and a survey with industry experts, finding as a result that the recognition of the competency of BIM practitioners is in demand and needs to be legalized with the recognition of experienced engineers via registration or licensing to include BPCs. This is an important step for removing artificial barriers to the free movement and practice of professional engineers amongst ASEAN countries. Additionally, evidence suggests that the BIM workforce’s benefits only become realizable when BIM certifications are systematic and recognized. Based on the survey results and expert interviews, BIM practitioners are certificated according to three main roles: manager, coordinator and modeler. Finally, a framework for issuing BPCs is proposed in this study. This study’s results are expected to contribute significantly to the success of BIM practitioner mobility among ASEAN member countries for sustainable economic development.
Competition in Knowledge Ecosystems: A Theory Elaboration Approach Using a Case Study
Authors: Robertson Jeandri
Published: September 2020

This paper explores how competition works in knowledge ecosystems, using a theory elaboration approach. With little research conducted in this area to date, three strategic streams of thought—resource-advantage theory, dynamic capabilities framework, and adaptive marketing capabilities perspective—are compared as a departing point and a frame of reference regarding the dynamics of competition. The streams of strategic thought all converge around the notion that organizations must constantly renew themselves to adapt and align to a fast-changing marketplace. The characteristics of knowledge ecosystems are conceptualized, whereafter an in-depth case study is presented to empirically assess competition in knowledge ecosystems, focusing on the perspective of a keystone actor. At the ecosystem-level, knowledge ecosystems primarily expose and explore knowledge, indicating that they mostly operate in a pre-competitive state. The time needed and the limited control inherent to knowledge exploration translate into the keystone actor focusing on transient rather than sustainable competitive advantage. Knowledge ecosystems further prove to be central in the coevolution and the growth of other ecosystems through connecting and sharing of the explored knowledge base with other ecosystem actors who, in turn, exploit this knowledge common for commercial purposes and innovation.
Country Brand Equity: The Decision Making of Corporate Brand Architecture in Cross-Border Mergers and Acquisitions
Authors: Barua Arup , Ioanid Alexandra
Published: September 2020

Cross-border merger and acquisition (CBM&A) is a dominant and sustainable antagonistic strategy, but a relevant concern like a country has inadequately been emphasized over the five decades of acquisition studies. Therefore, this article attempts to examine the impact of country brand equity (CBE) on corporate brand architecture (CBA) in post-CBM&A. It first originates a hypothetical model esteeming Resource-Based View (RBV) and Industrial Organization (IO) theory following the Structure-Conduct-Performance (SCP) paradigm. Then, it tests the model conducting a web survey on 124 acquiring corporates from 29 countries that accomplished CBM&A transactions between 1990 and 2014. The empirical findings clarify that the market aspect, such as the acquirer’s more substantial country brand equity, indirectly leads to the high degree of CBA standardization in the host market through prioritized intangible and strategic resources—corporate reputation and corporate brand management system. Individually, the acquirer’s corporate reputation cumulatively yields a high degree of CBA standardization with corporate brand power, which has only a direct effect. On the other hand, the corporate brand management system leads to a high degree of CBA standardization cumulatively with corporate reputation. It is deemed that the research findings as a whole reveal a framework for the application of country brand equity and corporate brand architecture in post-CBM&A.

Published: September 2020

The peristaltic flow of Johnson–Segalman fluid in a symmetric curved channel with convective conditions and flexible walls is addressed in this article. The channel walls are considered to be compliant. The main objective of this article is to discuss the effects of curvilinear of the channel and heat/mass convection through boundary conditions. The constitutive equations for Johnson–Segalman fluid are modeled and analyzed under lubrication approach. The stream function, temperature, and concentration profiles are derived. The analytical solutions are obtained by using regular perturbation method for significant number, named as Weissenberg number. The influence of the parameter values on the physical level of interest is outlined and discussed. Comparison is made between Jhonson-Segalman and Newtonian fluid. It is concluded that the axial velocity of Jhonson-Segalman fluid is substantially higher than that of Newtonian fluid.

This explorative cross-sectional study aims at exploring emotional distress, psychological profiles, and the attitude towards receiving psychological support in eighty-seven patients with chronic migraine (CM) undergoing OnabotulinumtoxinA prophylactic treatment (OBT-A, n = 40) or withdrawal treatment (WT, n = 47). The outcomes were explored through a specific battery of questionnaires. 25% of patients undergoing OBT-A and almost half of the patients undergoing WT reported psychological distress of at least moderate-severe level, respectively. Coping strategies, self-efficacy, and perceived social support were similar in the two groups. Patients undergoing OBT-A presented lower psychological inflexibility than patients undergoing WT. Predictors of higher psychological distress were low perceived social support by friends, low self-efficacy, and higher avoidance strategies. In both groups, most of the patients evaluated receiving psychological support to be useful (79%). The potential beneficial effects of OBT-A on the severity of symptoms and psychological distress might further support its role in the multidisciplinary management of patients with CM. Identifying patients with psychological vulnerabilities who may benefit from psychological support is relevant in patients with CM.
The State of the Art in Constraining Axion-to-Nucleon Coupling and Non-Newtonian Gravity from Laboratory Experiments
Authors: Mostepanenko Vladimir M. , Klimchitskaya Galina L.
Published: September 2020

Constraints on the Yukawa-type corrections to Newton’s gravitational law and on the coupling constant of axionlike particles to nucleons obtained from different laboratory experiments are reviewed and compared. The constraints on non-Newtonian gravity under discussion cover the wide interaction range from nanometers to millimeters and follow from the experiments on neutron scattering, measuring the Casimir force and Cavendish-type experiments. The constraints on the axion-to-nucleon coupling constant following from the magnetometer measurements, Cavendish-type experiments, Casimir physics, and experiments with beams of molecular hydrogen are considered, which refer to the region of axion masses from 10−10 to 200 eV. Particular attention is given to the recent constraints obtained from measuring the Casimir force at nanometer separation distance between the test bodies. Several proposed experiments focussed on constraining the non-Newtonian gravity, axionlike particles and other hypothetical weakly interacting particles, such as chameleons and symmetrons, are discussed.
LvYY1 Activates WSSV ie1 Promoter for Enhanced Vaccine Production and Efficacy

Published: September 2020

The baculovirus expression vector system (BEVS) has been used as a preferred platform for the production of recombinant protein complexes and efficacious vaccines. However, limited protein yield hinders the application of BEVS. It is well accepted that transcription enhancers are capable of increasing translational efficiency of mRNAs, thereby achieving better protein production. In this study, the ability of LvYY1 as a transcription enhancer was assessed. LvYY1 could interact with the WSSV ie1 promoter via binding to special DNA sites in BEVS. The effects of LvYY1 on protein expression mediated by WSSV ie1 promoter of BEVS was investigated using eGFP as a reporter gene. Enhanced eGFP expression was observed in Sf-9 cells with LvYY1. On this basis, a modified vector combining ie1 promoter and LvYY1 was developed to express either secreting CSFV E2 or baculovirus surface displayed H5 HA of AIVs. Compared to control groups without LvYY1, E2 protein yield increases to 1.6-fold, while H5 production improves as revealed by an upregulated hemagglutination titer of 8-fold at least. Moreover, with LvYY1, H5 displaying baculovirus driven by WSSV ie1 promoter (BV-LvYY1-ie1-HA) sustains the transduction activity in CEF cells. In chicken, BV-LvYY1-ie1-HA elicits a robust immune response against H5 AIVs in the absence of adjuvant, as indicated by specific antibody and cytokine responses. The findings suggest its potential function as both a vectored and subunit vaccine. These results demonstrate that the coexpression with LvYY1 serves as a promising strategy to extensively improve the efficiency of BEVS for efficacious vaccine production.
A Zigzag but Upward Way to Develop an HIV-1 Vaccine
Authors: Wen Ziyu , Sun Caijun
Published: September 2020

After decades of its epidemic, the human immunodeficiency virus type 1 (HIV-1) is still rampant worldwide. An effective vaccine is considered to be the ultimate strategy to control and prevent the spread of HIV-1. To date, hundreds of clinical trials for HIV-1 vaccines have been tested. However, there is no HIV-1 vaccine available yet, mostly because the immune correlates of protection against HIV-1 infection are not fully understood. Currently, a variety of recombinant viruses-vectored HIV-1 vaccine candidates are extensively studied as promising strategies to elicit the appropriate immune response to control HIV-1 infection. In this review, we summarize the current findings on the immunological parameters to predict the protective efficacy of HIV-1 vaccines, and highlight the latest advances on HIV-1 vaccines based on viral vectors.

Authors: Zanella Beatrice , Boccalini Sara , Bonito Benedetta , Del Riccio Marco , Tiscione Emilia , Bonanni Paolo ,   Working Group DHS,   Working Group AOUMeyer,   Working Group AUSLTC, Bechini Angela
Published: September 2020

Background: Despite the National Plan for the Elimination of Measles and congenital Rubella (NPEMcR), in 2017, a measles outbreak occurred in Italy, due to sub-optimal vaccination coverage (<95%) for many years. Since that year, the anti-measles vaccination became compulsory in minors (0–16 years) for school attendance. The aim of our study was to assess the immunity/susceptibility against measles in a representative sample of pediatric and adolescent (1–18 years) residents of the province of Florence (Tuscany, Italy), and to compare these results with two previous surveys (2003 and 2005–2006). Methods: The enzyme-linked immunosorbent assay (ELISA) was applied for a qualitative measurement of anti-measles antibodies on 165 sera. The anamnestic and vaccination status was also collected. Results: No measles notification was reported. The overall seropositivity was 88.5%; mostly in the 5–9 years old subjects (97.9%). Among the 152 vaccinated, 92.1% were positive. The seropositivity persisted after many years since the last dose of vaccine and tended to be more long-lasting in those who had received two or three doses. The susceptibility towards measles decreased over time, reaching a lower value in the current survey (8.5%) than in 2003 (30.8%) and in 2005–2006 (25.5%). Conclusions: This study confirmed the anti-measles vaccination campaign success, which allowed for the increase in vaccination coverage and immunity levels against measles in the Florentine pediatric and adolescent population following the NPEMcR implementation.

Published: September 2020

Brucellosis is a common zoonotic disease of major concern in humans of Kuwait, and B. melitensis causes most human cases. The disease is endemic in small ruminants, cattle, and camels for decades, causing substantial economic losses in livestock production. However, a nationwide large-scale investigation of brucellosis in the small ruminant population has not been done in the past two decades. A serosurvey of sheep brucellosis in the five districts of Kuwait with most animal production farms was done between 2016 and 2019. In total, 67,054 serum samples from 233 sheep herds were collected and tested. Additionally, milk and tissue samples were collected from 46 seropositive cases for bacteriology. Thirty persons from seven seropositive farms were tested by serology. The incidence of seropositive cases was 7% in districts devoid of vaccination, while it was 4.7% in farms with history of vaccination. The serosurvey revealed that 89% of non-vaccinated herds (n = 181) were seropositive by Rose Bengal test (RBT), buffered acidified plate antigen test (BAPAT), and complement fixation test (CFT). Prevalence of 100% was reported for non-vaccinated sheep herds from Al-Wafrah and Al-Jahra districts, followed by those from Al-Salmi (88.24%), Al-Abdali (86.7%) and Kabd (75.6%). Implementation of vaccination with B. melitensis Rev.1 vaccine and test-and-slaughters in 20 herds reduced the seroprevalence to 33.3% and 25% in herds from Al-Jahra and AL-Wafrah, respectively. B. melitensis was isolated from 20 samples (43.5%). More than half of the examined animal owners (56.6%) tested positive for Brucella using RBT, BAPAT and CFT. The high numbers of infected herds and high prevalence in herdsmen are alarming. Thus, control measures have to be ensured immediately. The epidemiological situation in Kuwait is similar to those of the neighboring countries and the combined action of these states is needed. The understanding of the economic and public health impact of brucellosis in Kuwait needs to grow.
The use of alternative feed protein from Musca domestica larvae in poultry
Authors: Larionova O. , Sarycheva A.
Published: September 2020

The results of numerous studies indicate that the biomass of Musca domestica larvae has great potential for use as a feed protein in animal husbandry. However, the issues of increasing the content of raw protein and improving the amino acid composition in the biomass of larvae remain open and require additional research. In addition, the study of the infl uence of such protein on the physiological and productive performance of broiler chickens has of scientifi c and practical interest. The purpose of the work was to develop a method for obtaining an alternative feed protein with an increased content of raw protein and improved amino acid composition. The larvae of Musca domestica have been used as a biological object of research, and chicken droppings have been used as a substrate. In order to conduct research a special insectarium has been equipped, in which the air temperature has been maintained at a stable level of 28–30 °C and a relative humidity of 60–70 %. Insects havebeen kept in special stationary cages. As a result of research, it has been found that the concentration of selenium and cobalt 15 mg/kg in the substrate is optimal for obtaining an alternative feed protein with an increased protein content and improved amino acid composition. The infl uence of microelements in the substrate composition on the chemical composition of the biomass of Musca domestica larvae has been revealed. The dynamics of the amino acid composition of the larval biomass has been studied using the proposed substrate. It has been found that the maximum content of many of the studied amino acids in comparison with the control was achieved after 48 hours of cultivation of larvae on the substrate with the addition of Se 15 mg/kg + Co 15 mg/kg. The maximum amount of lysine, phenylalanine, leucine+isoleucine, tyrosine was achieved after 48 hours, and histidine, valine, threonine, serine after 72 hours of cultivation. In addition, it has been found that the maximum concentration of raw protein was 61,72 % after 72 hours of cultivation. It has been found that the use of alternative feed protein from Musca domestica larvae in the feeding of cross Cobb 500 broiler chickens contributes to the improvement of physiological and productive parameters of the poultry. The revealed reduction in unit costs and increase in the gain of live weight of broilers leads to the decrease in prime-cost by 46 % and the increase in margin income by 149 %, and the level of profi tability by 110 %.

Measuring historical flooding and erosion in Goodnews Bay using datasets commonly available to Alaska communities
Authors: Buzard Richard , Maio Christopher , Verbyla David , Kinsman Nicole , Overbeck Jacquelyn
Published: September 2020

Coastal hazards are of increasing concern to many of Alaska’s rural communities, yet quantitative assessments remain absent over much of the coast. To demonstrate how to fill this critical information gap, an erosion and flood analysis was conducted for Goodnews Bay using an assortment of datasets that are commonly available to Alaska coastal communities. Measurements made from orthorectified aerial imagery from 1957 to 2016 show the shoreline eroded 0 to 15.6 m at a rate that posed no immediate risk to current infrastructure. Storm surge flood risk was assessed using a combination of written accounts, photographs of storm impacts, GNSS measurements, hindcast weather models, and a digital surface model. Eight past storms caused minor to major flooding. Wave impact hour calculations showed that the record storm in 2011 doubled the typical annual wave impact hours. Areas at risk of erosion and flooding in Goodnews Bay were identified using publicly available datasets common to Alaska coastal communities; this work demonstrates that the data and tools exist to perform quantitative analyses of coastal hazards across Alaska.

Published: September 2020

Beach nourishment has been widely used for beach protection around the world. However, there is limited information about beach nourishment in China. This study offers an overview of beach nourishment practices, status and technological advances in China, based on the literature, reports, and personal communications. The results demonstrate that beach nourishment has been recognized as an effective and environmentally friendly measure to combat coastal erosion and has been increasingly adopted in China, especially in the past decade. The unique characteristics of coastal China resulted in a difference in beach nourishment between China and Western developed countries in terms of the types, objectives, and shapes of beach nourishment. For the types of nourishments in China, there were approximately the same number of restored beaches and newly constructed beaches. For fill sediment, homogeneous fill and heterogeneous fill comprised 51.1% and 48.9% of projects, respectively. The objective of beach nourishment was mainly to promote coastal tourism, and the shape of nourished beaches was dominated by headland bays. This study also indicated that China has achieved a number of technological advances in beach nourishment, including methods of beach nourishment on severely eroded coasts and muddy coasts, an optimized design of drain pipes involved in urban beaches, and ecological design considerations. From the past decade of practices, four aspects were proposed as considerations for future nourishment: sand sources, technique advances, ecological effects, and management of beach nourishments.
Paternalismo industrial, empresa extranjera y campamentos mineros en América Latina: un esfuerzo de historia laboral y transnacional
Authors: Vergara Ángela
Published: September 2020

El presente trabajo analiza las prácticas paternalistas desarrolladas por los empresarios industriales y mineros latinoamericanos durante la primera mitad del siglo XX. Desde la perspectiva de la historia del trabajo y de los recientes debates sobre lo transnacional, este artículo busca reflexionar en torno a los elementos comunes del paternalismo industrial a lo largo del continente así como su impacto en la configuración de las relaciones laborales. A partir de este análisis, se plantea la importancia que tuvo el paternalismo como ideología patronal y símbolo de modernidad y progreso que buscaba crear una mano de obra eficiente y productiva. A pesar de los amplios beneficios sociales y de la construcción de modernas villas obreras y campamentos mineros, el paternalismo industrial en América Latina no desplazó las tradiciones más represivas del empresariado ni logró controlar a los trabajadores.
Herederas en el código civil: discursos y representaciones en torno a la capacidad jurídica de las mujeres
Authors: Coronello Romina Soledad
Published: September 2020

La preocupación por el lugar de la mujeres en los mecanismos de sucesión, ha sido abordada tangencialmente por estudios centrados en el siglo XIX, que analizan las redefiniciones jurídicas en torno a la familia, la propiedad y la herencia destacando cambios en la legislación familiar a partir de 1830. Por otro lado, los estudios de Dora Barrancos señalan la obturación de los derechos civiles de las mujeres y la consecuente inferiorizacion de la condición jurídica de la misma, sosteniendo la agudización de la subordinación legal femenina en el tránsito del siglo XVIII al XIX. Teniendo en cuenta estos aportes, nos proponemos comenzar a explorar las redefiniciones jurídicas del lugar de las mujeres en las dinámicas de sucesión del período. Para ello y como punto de partida de nuestra investigación, focalizaremos en este trabajo específicamente sobre las disposiciones del Código Civil de 1869 así como sobre las concepciones jurídicas y circunstancias que las explican en un intento por historizar las disposiciones en pos de esbozar cambios y continuidades, así como indagar sobre las representaciones que implican tales discursos.
Dictadura, democracia y clase obrera: los trabajadores ante el retorno al régimen constitucional en el noreste de Chubut
Authors: Pérez Álvarez Gonzalo
Published: September 2020

Nos interesa analizar una problemática de la historia reciente de Argentina: la situación que se plantea, una vez finalizada la última dictadura cívico-militar, para las organizaciones obreras, sus formas de lucha y su participación política y/o sindical. Se ha desarrollado un debate a nivel nacional, acerca de si esta dictadura generó una derrota que impidió a los trabajadores sostener formas de organización y lucha que hicieran posible la consecución de sus intereses. La mayoría de las investigaciones coinciden en que la clase obrera inició el régimen constitucional en un marco de gran debilidad, producto de esa derrota.Sin embargo, ésta no es la única mirada. Otras perspectivas sostienen que la dictadura no significó una derrota para el conjunto de los trabajadores sino que la misma se habría plasmado con la hegemonía del
Redes y dimensiones espaciales en la movilización por los derechos humanos en Argentina
Authors: Alonso Luciano
Published: September 2020

Las luchas en defensa de los derechos humanos en Argentina, desarrolladas hacia 1974-1983 frente al terror de Estado y redefinidas luego como reclamo de memoria, verdad y justicia, fueron llevadas adelante por agentes individuales y colectivos de muy variada índole, en localizaciones tanto del interior como delexterior del Estado nacional. El presente artículo presenta una serie de consideraciones a favor del estudio de distintos niveles espaciales para superar la descripción de las redes de movilización. Una explicación integral de esas luchas no sólo debe considerar la variedad de agencias y agentes intervinientes y contemplar las diferencias locales frente a la centralidad de Buenos Aires, sino también tratar de articular un esquema de comprensión teórico y conceptual que facilite una narración explicativa extensa.
La profesionalización de la educación sanitaria en la Argentina de los años sesenta: influencias internacionales, circuitos académicos y núcleos de formación técnica
Authors: Reyna Carla
Published: September 2020

En el presente trabajo se rescatan diferentes aspectos de los procesos de feminización y de profesionalización de la educación sanitaria en Argentina en los años sesenta. Con este propósito se analiza el influjo de los organismos internacionales de salud en interlocución con actores societales y estatales locales en los procesos de discusión, diseño y puesta en práctica de capacitaciones de diversa jerarquía. En este contexto se identificarán las discursividades que sustentaron la praxis profesional durante el período, enraizadas en las relaciones de género y en la construcción de identidades profesionales.
Representaciones en pugna: la Reforma Universitaria en el siglo XX
Authors: Bacolla Natacha , Mauro Diego
Published: September 2020

El texto se interroga acerca de la pervivencia y la naturaleza de las múltiples y por momentos antagónicas representaciones sobre el reformismo universitario a lo largo del siglo XX. Los artículos reunidos en el dossier, sugieren que, más allá de sus respectivos anclajes, el concepto de “Reforma Universitaria” adquirió rápidamente un uso político, deviniendo, en palabras del historiador Melvin Richter (2000), una noción “propiamente política” (p. 138). Esto es, un concepto que define su significado en la controversia y cuyo sentido deriva del propio hecho de estar sometido a la discusión desde diferentes posicionamientos y vertientes ideológicas e identitarias. En esta clave, el presente dossier se propone recorrer algunas de esas representaciones, apropiaciones y usos políticos.
“Á la vuelta de pocos años tendríamos regenerado nuestro servicio doméstico”. Las escuelas de sirvientas en la ciudad de Córdoba (Argentina, primeras décadas del siglo XX)
Authors: Remedi Fernando
Published: September 2020

Este trabajo se inserta en una línea de investigación sobre los pobres y la pobreza en Córdoba, Argentina, en el marco de grandes transformaciones producidas entre fines del siglo XIX y las primeras décadas del siglo XX, como la modernización material y social, la urbanización, la institucionalización estatal y el crecimiento económico. Dichos cambios fueron acompañados de una serie de desajustes sociales que afectaron a los sectores populares. En este contexto emergió un conjunto de prácticas destinadas a mitigar el déficit material y moral de esos grupos, que dibujaron fronteras difusas y móviles entre la sociedad civil y el Estado en la distribución de bienestar y la asistencia a los pobres. Nuestra atención se concentra en el servicio doméstico, integrado mayormente por mujeres pobres. En esta línea, este trabajo estudia las denominadas “escuelas de sirvientas” existentes en la ciudad de Córdoba en las décadas de 1910 y 1920, gestionadas por organizaciones benéficas y/o religiosas; se examinan sus objetivos y funciones, funcionamiento e impacto sobre el mercado laboral y sobre las domésticas. Se utiliza sobre todo la prensa, memorias de asociaciones benéficas y documentación administrativa de la Municipalidad de Córdoba.
A modo de presentación. Apuntes sobre la literatura de viajes
Authors: Galassi Gisela , Lollo María Soledad
Published: September 2020

Desde hace unas dos décadas, desde las Ciencias Sociales y Humanidades, se converge en nuevos estudios y “miradas”, en la escritura y la narrativa como núcleos que condensan perspectivas teóricas y epistemológicas insoslayables sobre la problemática del viaje y la literatura de viajeros. La transposición de la experiencia de viaje por medio de una narración, un discurso o un relato de viaje se constituye en problema per se a la vez que llega de diferente manera a públicos diversos. Esta “audiencia” cambia con el tiempo y el espacio aunque siempre será susceptible de ser impactada por la narración viajera. Pero un relato de viaje además de diferenciarse por su forma, por su cadencia de escritura, lo hará también por la marca en esa escritura de un eje sobre el cual se estructura el relato.
Ved en trono a la noble igualdad. Soñar con Rousseau en América Latina
Authors: Ansaldi Waldo
Published: September 2020

El artículo persigue el objetivo de mostrar, resumidamente, la impronta de Jean-Jacques Rousseau en los procesos independentistas latinoamericanos, particularmente su propuesta de una libertad igualitaria, que fue retomada por algunos de los más destacados dirigentes revolucionarios, sobre todo en el área rioplatense, donde Mariano Moreno, Bernardo de Monteagudo y José Artigas aparecieron como los más preclaros y decididos impulsores del pensamiento del ginebrino, el cual, por otra parte, llegó relativamente temprano al continente, donde fue perseguido por el Santo Oficio por postular la soberanía popular y la democracia. El artículo analiza también la relación entre ciudadanía, ciudadano y derecho, a la que no fue ajena la cuestión de género, como también la relación entre ciudadanía y libertad, considerada, por Moreno, como principio fundante de una nueva era, coherente con el proyecto emancipador generado por las proposiciones roussonianas. Finalmente, el artículo, si bien rescata la importancia de las ideas del ginebrino en las luchas por la independencia y por la constitución de un nuevo orden social y político, no deja de advertir el breve tiempo que tuvo la impronta de las mismas, derrotadas por propuestas de orden más moderadas, cuando no conservadoras.

The development of the multimedia model for the project: Teotihuacán on the time 2009-2019, aims to raise awareness of the damage suffered by the remains. Three factors that drastically affect this cultural heritage are being studied: mass tourism, climate change and tourist attractions within the archeological zone. The methodology for the implementation of the project is the software engineering prototype model that consists of five stages, the current status is stage three: design and construction. An instrument was applied to the inhabitants of the Teotihuacán Valley to probe the feasibility of implementing this multimedia in one of the museums of the archaeological zone, among the most outstanding results it was obtained that they have scarcely lived a multimedia experience within the facilities, for Therefore, the surveyed users consider that this development should raise awareness among both tourism and the population about the damage to the archaeological zone. Finally, the study revealed that software for this purpose is important. Subsequently, the instructional design e-activities specified in each of its phases was developed, such as access and motivation, online socialization, information exchange, knowledge construction and development.
