Determination of path attenuation and site characteristics of the North-west Himalayan region and adjoining regions within the Indian Territory using Generalized inversion method
Authors: Harinarayan Nelliparanbil , Kumar Abhishek
Published: December 2020

North-west Himalayas and its adjoining regions have been experiencing deadly earthqaukes from time to time and are home for a large portion of population of Indian subcontinent. Knowledge of regional path attenuation and site parameters are prerequisite while attempting seismic hazard studies towards minimizing damages during future earthqaukes for a region. Present work focuses on the determination of path attenuation and site characteristics of earthqaukes recording stations, located in the north-west Himalayas and its adjoining regions, within India. It is done using two- step generalized inversion technique. In the first step of inversion, non-parametric attenuation curves are developed by constraining attenuation to be a smooth decaying function with hypocentral distance. Qs = (105 ± 11)f (0.94 ± 0.08) as S wave quality factor is obtained indicating that the region is seismically active having high degree of heterogeneities in the crustal medium. In the second step of generalized inversion, site amplification curve, at each recording station, is computed as the ratio of site spectral amplitude of horizontal and vertical components. In addition, based on Horizontal to vertical spectral ratio (HVSR) method, predominant frequency of each recording station is calculated. Values of predominant frequencies based on HVSR and generalized inversion are found matching for each of the recording station. Based on obtained predominant frequency, site class of 101 recording stations, which at present are absent, are determined in this work. Determined path attenuation as well as site parameters can be collectively used for developing regional ground motion models and subsequently for seismic hazard studies for the selected region.
Effect of Time-strengthening Static Friction on Earthquake Recurrence
Authors: Wang Jeen-Hwa
Published: December 2020

he effect of time-strengthening static friction on earthquake recurrence is numerically studied based on the normalized equation of motion of a one-body spring-slider model with thermal-pressurized slip-weakening friction having the characteristic distance, Uc, which is in terms of static friction coefficient, 𝜇. Considering the time-strengthening static friction coefficient, 𝜇(𝑡) = 𝜇+𝐵×𝑙𝑜𝑔(𝑡), we assume Uc=Uco/(1+𝐵×𝑙𝑜𝑔(𝑡)). Simulation results exhibit that TR, 𝜏D, D, and Vm, which represent the recurrence time of two events, the duration time of slip of an event, the final slip of an event, and the peak value of particle velocity of an event, respectively, are all similar for five values of Uco when B<0.01 and clearly different when B≥0.01. In general, Vm, D, and TR increase with B; and 𝜏D slightly decreases with increasing B and increases with Uco. An increase in D is particularly remarkable when Uco>0.3. The earthquake recurrence is almost periodic for small Uco; while the degree of periodicity decreases when either Uco or B increases. Either the time-predictable model or the slip-predictable model can approximately interpret the simulated earthquake recurrences with small Uco and small B, yet not for those with large Uco and large B. Simulation results exhibit that time-strengthening static friction produce an opposite effect on earthquake recurrence from the time-widening slip zone.
Point wise Determination of Vertical Deformation at southern Coastal Areas of Caspian Sea by Combination of Satellite Altimetry and Tide Gauge Observations
Authors: Pirooznia Mahmood , Raoofian Naeeni Mehdi , Yousefzadeh Taghi
Published: December 2020

In this paper, a combination of satellite altimetry (SA) and tide-gauge (TG) observations is used to determine the pattern of vertical deformation at southern coasts of Caspian Sea. Satellite altimetry measures the variations of sea water surface with a respect to a reference ellipsoid, while tide gauge data gives the sea level relative to a particular ground station; consequently, the difference between these two observations will give the vertical motion at the ground station. However, altimeter satellites still have problems at shallow waters or coastal areas which leads to inaccurate and corrupted sea surface height at tide gauge stations. To minimize this imprecision, two strategies are applied for the selection of the suitable SA points near the TG stations. The First one is to choose those close passes to the TG stations, provided that the SA data is not corrupted (range observation is available). The second strategy is to extrapolate the SA points at TG stations using Spatio- Temporal Kriging method. In both point of views, use is made of re-tracking methods to improve the ranges of SA observations near the coast. Amplitudes of tidal components are removed from both SA and TG observations to derive the residual tide free signals. Afterward, a linear trend is fitted to the residual signals in the sense of least square; the difference between these two, supplies the vertical deformation of the ground station. The results illustrate that the average vertical crustal motion at Anzali, Noshahr and Neka are -1.387, -1.903 and -3.14 mm/year, respectively.
Time-invariance and geographical divide of earthquake mortality in Italy since 1800
Authors: Bragato Pier Luigi , Barnaba Carla , Scaini Chiara , Sugan Monica
Published: December 2020

We considered the mortality data of the earthquakes which occurred in Italy since 1800 and investigated their spatial-temporal characteristics. For this purpose, we developed a log-linear regression model relating the number of deaths to the magnitude of the earthquakes and analyzed the distribution of the residuals from the model. We found that, for fixed magnitude, the mortality of the earthquakes of the last decades is almost identical to that of the 19th century despite the fact that the population is decreasing in the small municipalities with high seismic hazard. There is also a geographical divide: for the same magnitude, an earthquake in southern Italy causes 2.9 times the number of victims than in northern Italy. The gap is partially justified by the higher population density in the seismic areas of southern Italy, while it does not seem to depend on seismological factors (seismic source, regional attenuation and site effects). The north/south divide increases to a factor of 8.3 for the earthquakes occurring between 00:00 and 05:00 a.m., when most people are sleeping and rely almost entirely on the strength of their houses for survival. We suggest that differences in the quality and maintenance level of the residential buildings are the primary factors determining this geographic divide, supported by data from a survey taken in 1934 and from the last general national census of 2011. Our results indicate that the situation of residential buildings in Italy requires a strict application of the seismic regulations as well as their extension to stimulate the correct maintenance and retrofitting of the existing buildings.
Crustal seismology: traditions and styles from a historical perspective
Authors: Anduaga Aitor
Published: December 2020

It has often been said that geophysics is an umbrella discipline, and that its various and varied fields remained conceptually autonomous even when configured in the mind of a single scientist. However, to what extent were these fields conceptually autonomous? Was there a single accumulation of geophysical knowledge and practices, or rather diverse traditions? Furthermore, what happens when there is a confluence of traditions rather than an independent accumulation of knowledge? Would it make sense then to talk about any conceptual autonomy and compartmentalized fields? This article examines the historical development of a geophysical specialization developed in multinational settings: crustal seismology. Rather than a conglomerate of autonomous fields, the view of geophysics as an intercalated set of inter-disciplinary fields, research schools, programs, and traditions which seem to concur in the same direction, can be applied to a large extent to geophysics of the Earth’s crust. The article shows how these elements interacted and were even transferred from one place to another. It concludes with some reflections on the institutional and procedural relations between academic geophysics, physics and geology.
New insights on the relative sea level changes during the Late Holocene along the coast of Paros Island and the northern Cyclades (Greece)
Authors: Kolaiti Eleni , Mourtzas Nikos
Published: December 2020

Geomorphological and archaeological indicators of former sea levels along the coast of Paros enabled us to determine and date six distinct sea level stands and the relative sea level (rsl) changes between them, as well as plot the rsl curve for the last 6,300 years. The Late Holocene history of the rsl change in Paros began with the sea level at 4.90 ± 0.10 m below mean sea level (bmsl) dated to the Late Neolithic period (4300 BC-3700 BC). The next sea level at 3.50 ± 0.20 m bmsl is dated to the Geometric and Archaic period of the Cyclades (1050 BC-490 BC) and most probably lasted during the Hellenistic period (323-146 BC). The sea level at 2.40 ± 0.25 m bmsl is dated to the Roman period (146-400 AD) and the next sea level at 1.35 ± 0.20 m bmsl to the Venetian period of the Cyclades (1207-1537). The sea level at 0.80 ± 0.10 m bmsl is dated to after the Venetian period, during the Ottoman rule of the island (1537-1821). The youngest sea level stand at 0.45 ± 0.10 m is attributed to the recent change in the sea level after the late 19th c. onward. The separation between glacio-hydro-isostatic signals and the observed rsl change on Paros Island, in an area of seismic quiescence, demonstrates a significant tectonic component in the rsl changes. Moreover, the sea level stands deduced from Paros in comparison with those from the northern Cyclades indicate a uniform tectonic behaviour of the entire northern and central section of the Cyclades plateau.

Hierophanies in the Vinland Sagas: Images of a New World
Authors: Foster Aidan
Published: December 2020

The field of Old Norse astronomy is in a very fragmented state. There is no primary source that describes all the heavenly bodies and constellations known to the Old Norse culture. Instead the researcher must go to a wide variety of sources, which sometimes only convey snippets of information. These sources range from Eddic poems to tales of early Icelandic astronomers and through to linguistic evidence, archaeology and folklore. The secondary material on these sources is also fragmented, since from the early twentieth century there have only been a few attempts at an overall grand narrative. In this paper a new approach is proposed to collecting and assessing this data. By using multi-disciplinary scholarship and a tripartite model, this paper will show how a new assessment of Old Norse astronomy can be put into practice for the twenty-first century.
The Representation of Astrology in Golden Age Spanish Theatre: Different Points of View in Calderon’s El astrologo fingido1
Authors: Lanuza-Navarro Tayra M. Carmen
Published: December 2020

This paper examines the representation of astronomical phenomena, and their astrological interpretation, in the Spanish theatre of the sixteenth century. The idea is not to use the plays as direct sources of information on the practice of astrology and also medicine, as has been previously done by Chevalier, Soufas and Sanchez Granjel.** Instead, I will look at the representation of astrology and its practitioners in theatre plays, considered as a cultural creation of their contemporary society. The first part of this study is focused on the representation of the variety of astrological practitioners, and how they dramatize the contact between academic astrology (taught at the universities) and other non-scholarly astrological practices, usually associated with magic and popular predictions. I also look at the interest of the general public in conventional representations of astrological theories.
Howard Russell Butler: Painter Extraordinary of Solar Eclipses
Authors: Sinclair Rolf
Published: December 2020

Howard Russell Butler (1856-1934) was a successful landscape and portrait painter who discovered a rare talent for seeing an image briefly and then painting it from memory and a few notes. He originally studied physics at Princeton, worked in the nascent telephone industry, and then practiced law. His avocational interest in painting grew until, at age 28, he made the decision to become a professional artist. He sometimes used his unusual talent to quickly sketch transient phenomena (or a busy patron) and then later finish the painting. Since colour photography was then unable to capture the phenomena visible only during a total solar eclipse, Butler was commissioned to capture the nuances and colours of the solar corona and prominences in the precious seconds of several eclipses. His paintings became astronomical classics. He went on to paint other astronomical themes (such as Mars seen from its Moon and design a museum’s Ideal Astronomic Hall, using the astronomical knowledge of his day. Although these scientific works were only a small part of his oeuvre, they mark him as one who uniquely brought together art and astronomy. This talk will show the range of Russell’s works and describe his unusual techniques.
Presentation of Playing the Stars
Authors: MacLennan Toby
Published: December 2020

This talk reports on a performance of the planetarium event Singing the stars with sculptures, which was performed at the H.R. Macmillan Planetarium in Vancouver and the Seneca College Planetarium in Ontario. Subsequent performances were done at the Art Gallery of Ontario, P.S.1, New York City, the 10th International Sculpture Conference, Toronto, and The National Gallery of Canada. It was reviewed in the Village Voice, Arts Canada, The New Art Examiner, Vanguard Magazine, and CBC Radio: Out of the belly of Vancouver’s H.R. Macmillan Planetarium, the star-making machine rises to the star chamber, carrying three musicians with their instruments, and three sculptures. Atop each sculpture is an overhanging frame of five wooden bars, which acts as a musical score. Lights go down over the planetarium audience. Stars move across the sky. Only the constellations and the luminous bars atop the sculptures are visible. Swept up by the grandeur of the constellations, the musicians look up through the bars atop their sculptures and give a concert playing the stars. The concert is inspired by a story from my book, Singing the Stars. A village of people has lost the power of night, which once resided within them. The people attempt to lure the night back with the help of sculptures, which will enable them to play and sing the stars. They hope that, lured by the music, the night will come close to their faces, and bits of darkness will fall into their ears, eyes and mouths and gradually fill up their bodies with the night sky.
Extending Vision: Sky-situated Knowledge and the Artist’s Eye
Authors: Spear Felicity
Published: December 2020

Increasingly, we are looking beyond our planet to speculate about our place in the Universe. In the context of ideas about the sky and cosmic space, art works have the potential to provoke curiosity and to play an educative and imaginative role in visualising connections with science, history and a space beyond the full range of our senses. While both artists and scientists reconstruct the material world on the basis of understanding, artists are able to exploit subjectivity and are not accountable to demonstrate proof. In this way, art seeks a poetic dimension or insight which speaks of things outside art in new or different ways. This paper discusses my recent research and the exhibitions I curated in order to coincide with the 2009 International Year of Astronomy. Included in these were an astro­photographer and a number of Australian artists, both Western and Indigenous, whose work has been influenced by the speculative and experimental processes involved with observation, image-capture and mapping, and the technological developments which shape human consciousness. They draw also on the history of human efforts to picture whatever lies beyond Earth’s atmosphere. This space, mostly beyond the naked eye, is revealed now through a machine-produced visibility which extends our vision. Together, these works show us how various systems of knowledge have sought to make sense of the cosmos and our place within it.

TO THE QUESTION ABOUT THE EPISTOLARY CULTURE OF STUDENTS IN CONDITIONS OF DISTANCE EDUCATION
Authors:   Tver State Technical University, Martyushov V.F. , Mikhailova E.E. ,   Tver State Technical University
Published: December 2020

Our question is what tasks a higher education teacher should set himself in the context of electronic communication. The teacher and student / master's student are seen as mediators between different epistolary styles. The teacher is seen as the guardian of the traditional style of emailing, and the student youth — as the creator of the new one. Examples are given to characterize the epistolary culture of students in the format of distance learning. As a result, it is argued that during educational correspondence between a teacher and a student, new standards of speech communication and new expressive means generated by the digitalization are formed.

The level of innovation of design, construction and technical and operational activities in modern cities is estimated. There was a need for a systematic approach to identify and address key industry problems. The possible methodology includes the selection and justification of technologies, space planning and architectural and structural solutions; analysis of interaction of architectural and landscape environment with artificially introduced abstractions, myths, symbols, ideal models and sign objects; combining the results of empirical data with the conclusions and consequences of «thought experiments» based on the use of modern IT-technologies. It is shown that a characteristic feature of the sphere of professional activity is the comparable scale of current problems solved at the regional and national level. We are considering the randomization of problems, the next relevant plan for linking to stages of the life cycle of a building/structure. The results of comparative analysis of industry complexes of different constituent entities of the Russian Federation are presented. The phenomenon of «unrealizability» of completed and funded projects is described.

ARCHITECTURAL ENVIRONMENT: SPACES, TERRITORIES, LOCIS
Authors:   Tver State Technical University, Fedorov V.V.
Published: December 2020

The structural organization of the city's architectural environment, including territories, spaces, and loci, is considered. It is shown that the architectural environment of the historical center of the city is characterized by special subject-spatial inclusions-loci of power. The complex dynamics of the interdependence of social existence and the architectural environment determines the relevance of studying the interaction of the locus (architecture) of power and society. The basic features of the architecture of power are considered: sociotechnical character, features of functioning, orderliness of the structure. The author analyzes the advantages and social significance of the power architecture, the latent features of the functional structure, the diachrony of compositional properties and the principles of ensuring closeness. The potential influence of power using architecture semantics is correlated with the processes of implementing algorithms for habitation, distribution, and dominance. The transformation of the status of the architectural space of power is considered not only as an architectural and planning transformation, but also as a change in its semantics and attitude to it. It is argued that the conceptualization of the locus (the assertion of authenticity) is converted into the popularity, influence, and economic growth of the locality. The social significance of loci of power is in their ability to subject-spatial modeling of social reality; in the formation of the potential for relieving social tension; in prompting the behavior of social actors in non-standard situations. It is noted that modern spaces of power are characterized by a gradual rejection of traditional closeness in favor of simulated openness. It is stated that the image of the architectural space of power is one of the angles of the socio-historical portrait of power.

COVID-19 PANDEMIC: AN OUTLINE OF DIGITAL LEARNING TOOLS FOR CREATING TEACHING AND LEARNING CONTENTS
Authors: Musa Saleh , Abdullahi Abubakar , Audu Hirhyel , Babagana Umar
Published: December 2020

There is currently little or no literature on COVID-19 in relation to educational studies especially in the area of continuous teaching and learning activities. The only literature available is directly related to medical studies. This is not because education is not directly affected by the effect of the COVID-19 pandemic but rather because studies in education rarely incorporate effects of disease on the effective provision of education to learners across the globe. The paper focused on the digital learning tools for creating teaching and learning contents at COVID-19 pandemic lockdown. The prime target of the researchers is to outlinethe digital learning tools as it is useful for creating teaching and learning contents for teachers at all level of education. There are many free and paid online digital learning tools available for creating teaching and learning content, such tools include: schoology; Google classroom; Edmodo; Moddle; Grockit; ePals and a lot but just to mention but few. The aforementioned tools were free for some extent, but teachers/tutors and students have to use internet for using these tools for long teaching and learning purpose. Some of the benefits of digital learning tools include the following; to reduce time and cost, issue of any pandemic or lockdown and maintaining social distance to minimize the spread of the disease more especially during pandemic. The paper therefore suggested that there is need for insights regarding the use of digital learning tools and teachers/tutors and students alike should consider digital learning tools for creating and continuous teaching and learning activities. The paper also recommended among others that educational stakeholders in Nigeria should provide training for teachers on how to use various digital learning tools in creating teaching and learning contents.

Published: December 2020

Alzheimer’s disease (AD) is the most common degenerative brain disease in the aged population [1]. By 2050, AD prevalence is expected to increase from 4.7 million (based on 2010 census) to 13.8 million people [2]. It is characterized by the progressive decline of cognition and memory, as well as changes in behavior and personality [1]. Pathological hallmarks of AD include mainly formation of senile plaques consisting of amyloid-beta (Aβ) peptide in the intercellular space and neurofibrillary tangles (NFTs) in the cell bodies, which are primarily composed of abnormally modified tau protein [3].

Huyện A Lưới của tỉnh Thừa Thiên Huế là nơi sinh sống của các nhóm dân tộc thiểu số Pa Cô, Tà Ôi với tập quán canh tác trên đất dốc và khai thác lâm sản từ rừng tự nhiên. Nhiều thay đổi trong sử dụng đất lâm nghiệp và tài nguyên rừng đã và đang diễn ra ở đây. Nghiên cứu đã chọn xã Hồng Kim để tiến hành khảo sát những thay đổi trong sử dụng đất lâm nghiệp của người dân địa phương. Thông qua phân tích định tính các thông tin thảo luận nhóm và phỏng vấn sâu, cùng với phân tích thống kê điều tra hộ, nghiên cứu cho thấy người dân xã Hồng Kim đã chuyển dịch từ canh tác nương rẫy sang trồng rừng và từ canh tác đa dạng sang độc canh. Những tác động dẫn dắt sự thay đổi này bao gồm cả chính sách đất đai và thị trường. Nghiên cứu đề xuất điều chỉnh quy hoạch sử dụng đất để tăng cơ hội tiếp cận đất đai cho người dân; xây dựng cơ chế hưởng lợi từ rừng cộng đồng, tạo sinh kế dưới tán rừng tự nhiên; tăng giá trị gia tăng từ rừng trồng, đồng thời tăng cường thực thi pháp luật để bảo vệ vốn rừng tự nhiên còn lại trên địa bàn; và xây dựng các mô hình nông lâm kết hợp để tăng tính đa dạng và nâng cao giá trị kinh tế của đất.

ABSTRACT

A Luoi district of Thua Thien Hue province is home to the Pa Co and Ta Oi ethnic groups with the practice of farming on sloping land and exploiting forest products from natural forests. Many changes in the use of forest land and forest resources have been occurring there. Hong Kim commune was selected in the study to survey forestry land use change. Through qualitative analysis of group discussions and in-depth interviews, along with statistical analysis of household surveys, the study showed that people in Hong Kim commune have converted forest land used for shifting cultivation to reforestation and from diverse farming systems to monoculture. The effects of driving this change included both land and market policy. The study proposed to adjust land use planning to increase opportunities for people to access land; building a mechanism for benefiting from community forests, creating livelihoods under the canopy of natural forests; increasing added value from planted forests while strengthening law enforcement to protect the remaining natural forest capital in the area, and building agroforestry models to increase the diversity and increase the economic value of the land.

Nghiên cứu này nhằm đánh giá ảnh hưởng của việc bổ sung cao chiết củ nén (CPN) vào trong nước uống đối với đáp ứng miễn dịch dịch thể chống lại virus Newcastle và năng suất sinh trưởng của gà thịt. Tổng số 180 gà trống Ri lai được úm cùng nhau đến 7 ngày tuổi. Sau khi được chủng vaccine Newcastle vào ngày 7, gà được phân bố ngẫu nhiên vào 04 nghiệm thức với 03 lần lặp lại. Gà ở các nghiệm thức T1, T2 và T3 được bổ sung 0,3, 0,5 và 0,7% CPN vào nước uống, liên tục từ ngày 7 đến ngày 42 tuổi và nghiệm thức đối chứng (ĐC - không sử dụng CPN). Vaccine Newcastle được tiêm lặp lại vào ngày 28. Hiệu giá kháng thể (GMT) trong huyết thanh chống lại bệnh Newcastle được xác định bằng cách sử dụng xét nghiệm ngăn trở ngưng kết hồng cầu (HI) lúc 21, 35 và 42 ngày tuổi. Kết quả cho thấy lượng ăn vào, tăng trọng, hệ số chuyển hóa thức ăn (FCR) và tỉ lệ chết khi kết thúc thí nghiệm không sai khác giữa 04 nghiệm thức. Tuy nhiên, hiệu giá kháng thể và tỷ lệ khối lượng cơ quan của hệ miễn dịch so với khối lượng cơ thể cao hơn (P<0,05) ở T2 và T3 so với đối chứng. Như vậy, việc bổ sung CPN trong nước uống không ảnh hưởng đến sinh trưởng; tuy nhiên, bổ sung CPN ở mức 0,5% và 0,7% đã làm tăng hiệu giá kháng thể dịch thể chống lại virus Newcastle ở gà thịt.

ABSTRACT

This study was conducted to investigate the effect of various levels of fresh chive’s bulb (Allium schoenoprasum) supplementation (CBE) in drinking water on immune status against Newcastle disease (ND) virus and productive performance of broiler chicken. A total of 180 Ri roosters were brooded at the same bath until 7 days  of age. After chickens had been vaccinated the Newcastle on day 7, they were randomly allocated into four treatments with 03 replicates as namely Control (no CBE), and T1, T2 and T3.  While a control group received no CBE, birds in groups T1, T2 and T3 received 0,3, 0,5 and 0,7 (w/v) CBE, respectively, continuously from day 7 to 42 years old. Newcastle vaccine was repeated on day 28. The geometric mean titer (GMT) against Newcastle disease virus was determined using the haemagglutination inhibition (HI) assay at 21, 35 and 42 days of age. The results showed that at the end of the experiment, the feed intake, average daily gain, feed conversion ratio (FCR) and overall mortality rate did not significantly differ among 04 treatments. Whereas, in general the antibody titer and the ratio of organ mass of the immune system to the body weight were significantly higher (P <0,05) in T2 and T3 than in the Control. Therefore, the supplementation of CBE in drinking water did not affect the growth performance. However, the supplement of 0,5% and 0,7% increased the antibody titre against Newcastle virus in broiler chicken.

Nghiên cứu này xem xét vai trò của đa dạng sinh kế đến “năng lực chống chịu” của hộ khai thác thủy sản biển ven bờ bị ảnh hưởng bởi sự cố môi trường biển Formosa năm 2016. Năng lực chống chịu của hộ được thể hiện thông qua mức độ tác động của sự cố và sự phục hồi sau sự cố. Các hộ được chọn nghiên cứu là hộ khai thác thủy sản biển gần bờ tỉnh Thừa Thiên Huế gồm nhóm chuyên khai thác thủy sản (KTTS) không đa dạng và nhóm KTTS đa dạng sinh kế. Kết quả nghiên cứu cho thấy, thời gian ảnh hưởng của sự cố đến nhóm hộ chuyên KTTS dài hơn nhóm hộ KTTS đa dạng sinh kế. Mặc dù giá trị thiệt hại về thu nhập của nhóm hộ KTTS đa dạng sinh kế cao hơn (khoảng 307,53 triệu đồng), nhưng tỷ lệ thiệt hại so với thu nhập của nhóm hộ này thấp hơn so với nhóm hộ chuyên KTTS (107,1% so với 123,31%). Sau 30 tháng, nhóm KTTS đa dạng sinh kế có quá trình phục hồi tốt hơn với tỷ lệ giá trị thu nhập phục hồi khoảng 77,88%, cao hơn khoảng 10% so với nhóm còn lại. Đa dạng sinh kế của hộ KTTS được xem là yếu tố ảnh hưởng tích cực nâng cao năng lực chống chịu của hộ đối với sự cố môi trường và phục hồi các hoạt động sinh kế.

ABSTRACT

This study examined the role of livelihood diversity on the resilience capacity of coastal fishing households affected by the Formosa incident in 2016. The resilience capacity of househoulds was characterized by the impact level of the incident and post-incident recovery. The households selected in this study were nearshore fishing groups in Thua Thien Hue province, including two fishing groups of undiversified and diversified livelihood. The results showed that the impact duration of the incident on undiversified livelihood fishery group was longer than that on the diversified livelihood group. Although the value of income loss of the households group with diversification was higher (about 307.53 million VND), the rate of income loss of this group was lower than that of their counterparts (107.1% compared to 123.31%). After 30 months, the diversified livelihood group had better recovery with the proportion of income recovered at roughly 77.88%, about 10% higher than that of the other group. Diversified livelihood of fishing households was considered as the positive influence on improving their resilience to environmental incidents and restoration of livelihood activities.

Published: December 2020

Renewable natural gas (RNG), also known as biomethane or upgraded biogas, is growing in prominence as a strategy to help achieve state climate, waste management, and other sustainability goals. However, questions remain on whether projects can be easily deployed, the extent to which they can contribute to ambitious climate and environmental goals, and the trade-offs of supporting RNG versus alternative decarbonization strategies. This paper provides comprehensive guidance for policymakers on evaluating RNG resource potential, greenhouse gas emissions impacts, and deployment and policy options at the state level.

The organization known as Srpska desnica (SD; the Serbian Right Wing) during 2019 become increasingly seen in the Serbian media, as well as receiving augmented visibility on posters throughout the country. With their recent electoral success in the town of Medveđa, as well as their announcement that they are turning into an official party that would enter the 2020 parliamentary elections, coupled with the troublesome past of their leader, Miša Vacić, the situation calls for investigation. In this article, we are putting Miša Vacić’s public and political engagement under a magnifying glass, positioning him within the broader nationalist political spectrum of the country, engaging his official political program. We shall furthermore define the concept of the political scarecrow, a political party or figure that serves primarily to frighten, as shall be clear from the case study that this is the role of his organization.
