VNIR HYPERSPECTRAL ANALYSIS OF RAMGARH ASTROBLEME IN NORTHERN INDIA
Authors: Tripathi P. , Garg R. D.
Published: February 2022

Abstract. Hyperspectral remote sensing has immense potential to characterize any surface by utilizing the detailed spectral information obtained from hundreds of narrow and contiguous bands. This work utilizes the latest DESIS (DLR Earth Sensing Imaging Spectrometer) hyperspectral data from the Ramgarh astrobleme (crater) in the state of Rajasthan, India to identify the surface geology and the changes that have undergone. Vertex Component analysis has been applied on DESIS data, and the output end members were compared with the reference spectra from the spectral library. However, due to the amount of vegetation in the study area, the Vegetation Response Removal (EVRR) thresholding model is proposed to remove the effect of vegetation. With the application of EVRR, the presence of quartz with impurities is noticed.
Classifying offshore faults for hazard assessment: A new approach based on fault size and vertical displacement
Authors: Laor May , Gvirtzman Zohar
Published: February 2022

Abstract. For many countries, the methodology for offshore geohazards mitigation lags far behind the well-established onshore methodology. Particularly complicated is the mapping of active faults. One possibility is to follow the onshore practice, i.e., identifying a sub-seabed Holocene horizon and determining whether it displaces this horizon for each fault. In practice, such an analysis requires numerous coring and often ends without an answer. Here we suggest a new approach aimed for master planning. Based on high-quality seismic data, we measure for each fault the amount of its recent (in our specific case 350 ky) displacement and the size of its plane. According to these two independently measured quantities, we classify the faults into three hazard levels, highlighting the “green” and “red” zone for planning. Our case study is the Israeli continental slope, where numerous salt-related, thin-skinned, normal faults dissect the seabed, forming tens of meters high scarp, which are crossed by gas pipelines. A particular red zone is the upper slope south of the Dor disturbance, where a series of big listric faults rupture the seabed in an area where the sedimentation rate is four times faster than the displacement rate. We suggest that this indicates seismic rupture rather than creep.
GNSS signal-based snow water equivalent determination for different snowpack conditions along a steep elevation gradient
Authors: Capelli Achille , Koch Franziska , Henkel Patrick , Lamm Markus , Appel Florian , Marty Christoph , Schweizer Jürg
Published: February 2022

Abstract. Snow water equivalent (SWE) can be measured using low-cost Global
Navigation Satellite System (GNSS) sensors with one antenna placed below the
snowpack and another one serving as a reference above the snow. The
underlying GNSS signal-based algorithm for SWE determination for dry- and
wet-snow conditions processes the carrier phases and signal strengths and
additionally derives liquid water content (LWC) and snow depth (HS). So far,
the algorithm was tested intensively for high-alpine conditions with
distinct seasonal accumulation and ablation phases. In general, snow
occurrence, snow amount, snow density and LWC can vary considerably with
climatic conditions and elevation. Regarding alpine regions, lower
elevations mean generally earlier and faster melting, more rain-on-snow
events, and shallower snowpack. Therefore, we assessed the applicability of
the GNSS-based SWE measurement at four stations along a steep elevation
gradient (820, 1185, 1510 and 2540 m a.s.l.) in the eastern Swiss Alps
during two winter seasons (2018–2020). Reference data of SWE, LWC and HS
were collected manually and with additional automated sensors at all
locations. The GNSS-derived SWE estimates agreed very well with manual
reference measurements along the elevation gradient, and the accuracy
(RMSE = 34 mm, RMSRE = 11 %) was similar under wet- and dry-snow
conditions, although significant differences in snow density and
meteorological conditions existed between the locations. The GNSS-derived
SWE was more accurate than measured with other automated SWE sensors.
However, with the current version of the GNSS algorithm, the determination
of daily changes of SWE was found to be less suitable compared to manual
measurements or pluviometer recordings and needs further refinement. The
values of the GNSS-derived LWC were robust and within the precision of the
manual and radar measurements. The additionally derived HS correlated well
with the validation data. We conclude that SWE can reliably be determined
using low-cost GNSS sensors under a broad range of climatic conditions, and
LWC and HS are valuable add-ons.
Recelo y admisión del elemento democrático en el Leviatán de Hobbes.
Authors: Galimidi José Luis
Published: February 2022

Hobbes  mantiene una actitud dual respecto de la participación política en general, y de la forma democrática de gobierno, que es la universalización del impulso participativo, en particular. La teoría desarrollada en el Leviatán, de un lado, incorpora el elemento participativo como expresión eminente de la voluntad de poder, a la vez que, del otro, trata de contener sus previsibles inconveniencias mediante una adecuada comprensión del correcto diseño y manejo de la máquina del Estado. Las críticas de Hobbes al talante democrático, que, desde una perspectiva contextualista, pueden ser consideradas como intervención ideológica antirrepublicana, también pueden ser estudiadas con provecho si se las ve como un corolario de su concepción de la naturaleza humana. La evidente contradicción de postular un momento inicial de máxima libertad fundadora, para luego constreñirla a la mera aceptación de las disposiciones del gobierno absoluto, más que como inconsistencia, puede verse como lúcida aprehensión de las tensiones propias de la estatalidad barroca. Se trata, entendemos, de conciliar la preeminencia del vector de soberanía con la protección de la necesidad subjetiva de participación en las diferentes instancias de ejercicio del poder. A tal efecto, el Leviatán contempla previsiones para el fortalecimiento de la actividad económica, así como para el de la autoridad de los funcionarios públicos.

The education policy of the First Democratic Republic of Georgia, published in the Georgian party press of 1918-1921
Authors: Macharashvili Tinatin
Published: February 2022

We present the education policy of the years of the first Republic of Georgia (1918-1921) by observing the main newspapers of the mentioned period ( "Ertoba", "Sakhalkho Sakme", "Sakartvelo", "Sakartvelos Republika").

As you know, the young democratic republic faced many problems. Addressing the issue of nationalization was largely based on a fundamental transformation of the education system. The return of the native language, first of all, required the Georgianization of the educational program, which, in turn, required both material and intellectual resources. Membership of a large European family was associated with the revival of science in Georgia. The issue of Georgia's territorial integrity was also directly related to public education. Accordingly, the education policy of the Sovereign Republic had to be considered in different contexts.

Although not a single work has been devoted to the life of Georgia during the years of independence, they are mainly of a historiographical nature. Our research, in particular, focuses on the specifics of the education policy presented in the media, and in-depth research of the issue in this regard is the main task. Based on the theories of media effects, in particular agenda setting and framing, we have outlined the role of the media in leading to a highly contradictory path to education reform.

It turned out that the formation of an education system in the Georgian multi-party press was one of the priority issues and different parties pursued a uniform policy on this issue. The media message was as follows: we would connect Europe with the development of science, and we would become a member of the European family only if we were a full-fledged nation. The framework of these messages is defined by the spatial orientation of Georgia - Georgia, not through Russia, but should be directly connected to Europe.

E EVALUASI PRODUKSI RIPPING OVERBURDEN UNTUK MENCAPAI TARGET PRODUKSI 190.000 BCM PADA BULAN MARET 2021 DI PIT CRM PT DUTA ALAM SUMATERA, LAHAT, SUMATERA SELATAN
Authors: Sepriadi Sepriadi , Gusman Subandi
Published: February 2022

Ripping overburden oleh bulldozer ripper Komatsu D155A merupakan faktor utama tercapai atau tidaknya target produksi overburden pada bulan Maret 2021. Berdasarkan data bahwa produksi overburden pada bulan Maret 2021 belum tercapai yaitu 158.787 BCM dari rencana produksi 206.654 BCM. Hal ini dikarenakan kemampuan ripping oleh bulldozer ripper Komatsu D155A di lapangan belum dapat bekerja maksimal. Produksi aktual ripping adalah 138.470 BCM dari rencana 190.000 BCM. Tentunya penurunan kemampuan produksi ripping ini disebabkan oleh faktor jenis material overburden dan efisiensi kerja yang masih buruk. Terdapat tiga langkah perbaikan yang dilakukan. Perbaikan pertama pada efisiensi kerja, usaha yang dapat dilakukan untuk meningkatkan waktu kerja efektif dengan cara meningkatkan kedisiplinan waktu kerja karyawan dengan toleransi lima menit tiap waktu hambatan seperti terlambat mulai kerja, terlambat setelah istirahat, terlalu cepat beristirahat dan berhenti sebelum pulang. Selain itu peningkatan pengawasan oleh foreman atau supervisor harus tetap terjaga ketika sudah mulai bekerja sampai akhir bekerja tiap shift. Dengan melakukan kedisiplinan waktu kerja dan pengawasan pada operator ini dapat meningkatkan efisiensi kerja dari 61% menjadi 64% dengan jumlah produksi 122.732 BCM. Selanjutnya perbaikan kedua pada penetrasi ripper dengan menerapkan spasi ripping per 3 m pada area front kerja 15x15 m pada material sandstone dan mudstone untuk mengurangi tingkat keausan pada ripper dan tidak terlalu memaksa kinerja mesin. Sehingga penetrasi ripper dapat meningkat dari rata-rata 0,64 m menjadi 0,8 m menghasilkan produksi ripping 175.770 BCM. Terakhir perbaikan yang ketiga pada kedua faktor atau penggabungan perbaikan terhadap efisiensi kerja menjadi 64% dan rata-rata penetrasi ripper 0,8 m, didapatkan perhitungan teoritis produksi ripping overburden 191.768 BCM. Jadi, solusi yang terbaik agar mampu mencapai target ripping overburden pada bulan selanjutnya dengan melakukan perbaikan terhadap faktor gabungan antara penetrasi ripper dan efisiensi kerja di pit CRM.
Board Attributes and Corporate Governance Soundness in Listed Oil and Gas Companies in Nigeria
Authors: Eke Gift O.
Published: February 2022

This study investigated the association between board attributes and corporate governance soundness in listed oil and gas companies in Nigeria. The study adopted the ex post facto research design since it was a secondary data research. The twelve (12) oil and gas companies listed on the Nigerian stock exchange between 2010 and 2018 constituted the population of the study. A census of the entire population was done since the population was small. Content analysis was used to extract data required for the study from the audited financial statements of the listed oil and gas companies that were sampled. Analysis of data was done using descriptive statistics and the hypothesis postulated was tested using correlation and multiple regression statistics. The study revealed that there is no significant association between board attributes and corporate governance soundness in listed oil and gas companies in Nigeria given the weak average coefficient of correlation of 36.8 percent. The study further revealed that board attributes influence corporate governance soundness by only 14.5 percent. Given the findings of the study, it is concluded that board attributes (board independence, board size and board meetings) correlate positively, albeit insignificantly, with corporate governance soundness. One of the recommendations made was that the board of directors of listed oil and gas companies in Nigeria should continually rally round, and be committed to involving, the various stakeholders in corporate governance in the governance process.

Dünyanın birbiriyle daha entegre olduğu ve bütünleştiği dönem küreselleşme çağı diye isimlendiriliyor. Sermayenin, ürünlerin ve fikirlerin serbestçe dolaşıma girdiği bu dönemde sermaye, ürünler ve fikirler kadar olmasa da bir insan hareketliliği de yaşanmıştır. Gerek işçi göçüyle gerekse de ulaşımdaki gelişmelerin sayesinde turizmle insanların farklı ülkelere ve haliyle farklı kültürlere seyahati de mümkün olmuştur. Bu gelişmelerin etkisiyle farklı kültürler de küresel düzeyde etkileşime girmiş, teknolojinin ve iletişim araçlarının gelişimi ile yerel kültürler de zenginleşmiş, zenginleşmenin yanında belli seviyede homojenleşme de gerçekleşmiştir. Fakat zorunlu göç kapsamında insanların başka ülkelere seyahatinin artmasıyla birlikte kültürün mobilizasyonuna tepkiler de artmaya başlamıştır. Göç eden insanların sosyo-ekonomik seviyelerinin düşük olması ve hayat tarzlarındaki farklılıklar ve göç ettikleri yerlerdeki yaşam tarzına ve kültürel unsurlarına adapte olmakta zorluk yaşamaları hem göçmenlere karşı tepkileri artırmış hem de küreselleşme ve kültürdeki homojenleşmeyi azaltmıştır. Dünya da ayrımcılığa dayalı popülist politikaların da yükselişe geçtiği bir dönemde göçmenler bundan olumsuz etkilenmişlerdir. Küreselleşme de bundan zarar görmüş ve insanlar eskiden benzerlikleri üzerinden bir ilişki zemini kurarlarken şimdilerde farklılıkları üzerinden birbirlerini ötekileştirmeye başlamışlardır.

Çalışanların bedensel ve ruhsal sağlıklarının korunduğu bir ortamda iş görmeleri hem bireysel hem de toplum yararına hizmet etmektedir. İş sağlığı ve güvenliği açısından risk düzeyi, faaliyette bulunulan sektöre göre farklılık arz etmektedir. Sektörlerin risk düzeylerinin saptanması, ortaya çıkabilecek olumsuz durumları minimize etmeye yardımcı olacaktır. Bu amaçla araştırmada iş kazaları ve meslek hastalıklarını temsil eden 7 kriter belirlenmiş, ekonomik faaliyet sınıflamasında yer alan 88 sektör ise alternatif seti olarak ele alınmıştır. Analizlerde, Sosyal Güvenlik Kurumunun yayımladığı 2020 yılı istatistikleri kullanılmıştır. Gri İlişkisel Analiz (GRA) yöntemiyle öncelikle kriterlerin eşit öneme sahip olduğu varsayılarak bir sıralama elde edilmiştir. Ardından kriter ağırlıklarının objektif olarak belirlendiği CRITIC yöntemiyle Gri ilişkisel analiz yöntemi birlikte kullanılarak yeni bir sıralama yapılmıştır. Her iki durumda da iş sağlığı ve güvenliği açısından en riskli sektörün bina inşaat olduğu, ikinci ve üçüncü sıralarda ise fabrikasyon metal ürünleri imalatı ve insan sağlığı hizmetleri olduğu saptanmıştır. Risk seviyesinin en düşük olduğu sektörler ise uluslararası örgütler ve temsilcilik faaliyetleri ile hane halkları tarafından kendi kullanımlarına yönelik olarak üretilen ayrım yapılmamış mal ve hizmetler olarak belirlenmiştir.

Günümüzde bilim ve teknolojinin hızlı gelişimi ve küreselleşmeye yönelik eğilimlerle birlikte, neredeyse tüm örgütler muazzam riskler ve rekabet baskıları getiren dinamik bir iş ortamıyla karşı karşıya kalmaktadır. Yenilikçi davranış, örgütlerin uzun vadede hayatta kalması ve sürdürülebilir bir rekabet avantajı elde etmesi için benzersiz bir varlık olarak kabul edilmektedir. Öte yandan, çok sayıda bilim adamı sosyal sermaye ve girişimciliğin yenilikçi davranış üzerindeki etkisine dikkat çekmektedir. Bu perspektiften Gaziantep’teki 404 Suriyeli girişimcinin katıldığı çalışmanın temel amacı sosyal sermayenin yenilikçi davranış üzerindeki etkisini ve bu etki düzeyinde girişimcilik eğiliminin aracılık rolü olup olmadığını incelemektir. Kavramsal ve ampirik araştırma sonucu elde edilen bulgular sosyal sermayenin hem doğrudan hem de girişimcilik eğilimi aracılığıyla dolaylı olarak yenilikçi davranışı olumlu bir şekilde etkilediğini ve ayrıca sosyal sermayenin yenilikçi davranış üzerindeki etkisinde girişimcilik eğiliminin kısmi aracılık rolü de doğrulanmıştır. Bu sonuçlar sosyal sermayenin girişimcilik eğilimi aracılığıyla girişimcilerin işlevselliğini daha da artırarak daha fazla yeni yaratıcı fikirler ürettikleri ve uyguladıkları argümanına güçlü bir destek sağlamaktadır.

Thần thoại Hy Lạp là một trong những di sản văn hóa vĩ đại của nhân dân Hy Lạp cổ đại. Thần thoại không đơn giản chỉ là một tác phẩm văn chương được tạo ra qua trí tưởng tượng của con người, mà đó còn là những tri thức về lịch sử, nghệ thuật và văn hóa. Trong khuôn khổ bài viết, tác giả muốn thông qua hình ảnh các vị thần linh trong thần thoại Hy Lạp để chỉ ra sự phát triển về mặt kinh tế của nhà nước Hy Lạp thời kỳ cổ đại thông qua cách tiếp cận đa chiều giữa sử học và văn học.
Cảm hứng hiện sinh trong sáng tác của Nguyễn Thị Thụy Vũ
Authors: Ngô Thị Diệm
Published: February 2022

Văn chương, đặc biệt là những tác phẩm văn chương giá trị có cách tồn tại riêng bất chấp quy luật của thời gian. Sau hơn 40 năm vắng bóng trên văn đàn do những biến động của lịch sử, năm 2016, 2017 toàn bộ mười tác phẩm của Nguyễn Thị Thụy Vũ đã một lần nữa đến với bạn đọc. Sự đón nhận hân hoan của độc giả cũ và sự ngỡ ngàng, thích thú của lớp độc giả mới đã chứng minh sức hút vượt thời gian của chúng. Được đánh giá là một trong năm nữ nhà văn nổi tiếng của văn chương đô thị miền Nam 1954-1975, Nguyễn Thị Thụy Vũ đã có những đóng góp tích cực về mặt thể tài cùng phong cách nghệ thuật độc đáo. Khảo cứu tác phẩm của nữ nhà văn cho thấy, hoạt động sáng tác của bà có sự ảnh hưởng của văn học hiện sinh dù không đậm đặc. Cảm hứng hiện sinh mang đến trong tác phẩm hình ảnh con người cô đơn trong một thế giới đầy biến động và nỗi ưu tư, khát vọng vươn lên, tìm kiếm và chứng minh nhân vị độc đáo của mình. Vì chất hiện sinh không đậm nên văn chương Nguyễn Thị Thụy Vũ không mang tính triết lý nhưng là những trải nghiệm, suy tư, trăn trở của con người trước cuộc đời.

Scoliosis is a disease caused by the abnormal curvature of spine. Generally, curvature above 10 degrees is considered as a scoliosis. About 2-4% of the world population is affected by this disease. Therefore, there is a need for such a tool that can help surgeons and bioengineers to study the behavior of a spine under various conditions. Considering the engineering perspectives, it is necessary to understand the fundamental anatomy of the human spine and pathological techniques associated with the orthopedic conditions, so that better technologies can be implemented. The main objective of this work is to develop a 3D model that can simulate various orthopedic conditions associated with the change in Cobb angle. CT scans of patients are obtained from the Spine center of G. hospital, Lahore. 3D Models of actual patients are created using 3D Slicer and Radiant software. Only spine portions are extracted to understand the type of scoliosis, curvature region, and Cobb angles. The cobb angle of each of the patients is measured using Solid Works software. Considering the real data of patients, the severity level of scoliosis in the patients is discussed. Keywords: anthropometry; Cobb angles; CT scans; scoliosis; Spine deformity; vertebra.

The poison contained on the skin and in the glands of the Bufonidae has a digital is toxicity and carries a high mortality. Toad venom was considered responsible for the development of severe clinical manifestations such as vomiting, diarrhea, neurological disorders and arrhythmias. If not readily recognized by the clinician, this type of intoxication can be fatal. Prompt treatment with digoxin specific Fab fragment antibodies may be lifesaving in the treatment of toad venom poisoning. This case report alerts physicians to the need to be aware of this rare toxin. Keywords: toad venom intoxiacation; third-degree AV block; digoxin specific fab fragment antibodies.

While countless studies on the role of clusters in regional economic developments and business performance have been done, some disadvantages and limitations also have been identified. Limitations such as small local markets, limited resources, isolation, and over-independence which lead companies to a lock-in state regarding knowledge and innovation can be solved by means of internationalization or foreign market expansion. Therefore, the internationalization of clusters still needs more attention. Furthermore, by conducting a bibliometric study based on the keywords from previous research, this investigation intends to identify the principal and most influential items, their relationship, and evolution, related to this topic. This work listed the top 30 journals based on SCImago Rank (SJR) in the category of Marketing, Management, and Internationalization, to select authoritative papers on the topic of internationalization of clusters. Based on the title, time of publication (2009 to 2018), and content, 152 articles were selected. Using SciMAT software, all 584 keywords used in these articles were first categorized and then examined in terms of the networks between them, their h-index, centrality, density, and their evolution over the course of ten years (divided into two five-year periods). The results show that in the first five years, keywords such as, Network, Location-distance, and Global, have been at the core of this research topic. While in the second five year period, these keywords have yielded their position to new subjects such as Social capital, Cluster-type, and Development. Moreover, this research correspondingly confirms that the keyword bibliometric analysis produces similar results to a quantitative content analysis. These results therefore open the door to updated research questions for further and better development of the topic.

This study shows the main results of a bibliometric analysis of academic research that has applied eye tracking technology in the marketing discipline, drawing from 923 documents extracted from the WoS bibliographic data-base. The aims of the study are to (i) identify the structure of the relationships between past and current research topics, (ii) provide a longitudinal perspective on eye tracking as a research tool for academics, covering the period 1992-2020, and (iii) identify emerging research trends for the future. Among other results, we find that the eye tracking methodology has been applied in marketing research particularly over the last decade due to scholarly interest in studying the visual attention of consumers and users in behavioral studies. More broadly, over the last 30 years, there are five major thematic areas identified: (a) brand-attention-modeling, (b) eye tracking-movements-communication, (c) web-online, (d) HCI-gaze-perception and (e) choice-labeling. The work is the first to identify the structure of the relationships between past and current research topics, and to predict future research trends in the marketing scholarship applying eye tracking as a research tool. Some limitations and potential future research themes are discussed at the end of the paper.
Concept App Development for National Library of Virtual Manipulatives (NLVM): An Initiative
Authors: Islam ABM Rezbaul , Bullock Emma
Published: February 2022

An NSF-supported project, the National Library of Virtual Manipulatives (NLVM), was started in 1999 to develop a library of entirely interactive and web-based virtual manipulatives or concept tutorials. It was mainly in Java applets for mathematics instruction (K-12 emphasis). The NLVM was a resource to develop mathematics classrooms from which teachers could independently draw upon. The materials were also significant in the mathematical training of both in-service and pre-service instructors. However, twenty years later, with the proliferation of touch-screen devices, this fantastic resource is in a crisis of becoming lost to future generations. It has been seen that many computers no longer run Java. Besides, the older version of Java used in the initial advancement of the NLVM is no longer supported. Hence, it is the right time to rethink the NLVM for current, widely available touch screen devices. This is essential to bolster the offerings for both prekindergarten, K- 12, and university settings. Keeping the situation in mind, we have constructed four virtual manipulative applications compatible with touch-screen devices based on the outdated java-script types of virtual manipulatives available through the NLVM. The four concept apps are being conducted with children in classroom settings starting in Spring 2021. It will allow for further revisions of the apps if necessary. Then, the apps from this project would be combined as part of a more significant, federally, or privately funded external grant proposal to re-imagine and broaden upon all the virtual manipulatives currently found in the NLVM.
