AMR Compressed-Domain Analysis for Multimedia Forensics Double Compression Detection
Authors: Sampaio José Fabrizio Pereira
Published: August 2020

An audio recording must be authentic to be admitted as evidence in a criminal prosecution so that the speech is saved with maximum fidelity and interpretation mistakes are prevented. AMR (adaptive multi-rate) encoder is a worldwide standard for speech compression and for GSM mobile network transmission, including 3G and 4G. In addition, such encoder is an audio file format standard with extension AMR which uses the same compression algorithm. Due to its extensive usage in mobile networks and high availability in modern smartphones, AMR format has been found in audio authenticity cases for forgery searching. Such exams compound the multimedia forensics field which consists of, among other techniques, double compression detection, i. e., to determine if a given AMR file was decompressed and compressed again. AMR double compression detection is a complex engineering problem whose solution is still underway. In general terms, if an AMR file is double compressed, it is not an original one and it was likely doctored. The published works in literature about double compression detection are based on decoded waveform AMR files to extract features. In this paper, a new approach is proposed to AMR double compression detection which, in spite of processing decoded audio, uses its encoded version to extract compressed-domain linear prediction (LP) coefficient-based features. By means of feature statistical analysis, it is possible to show that they can be used to achieve AMR double compression detection in an effective way, so that they can be considered a promising path to solve AMR double compression problem by artificial neural networks.

Published: August 2020

In a reality of clashing visions and perspectives, vision becomes murky, foundations become shaky, and smoky fumes rule over all. History tends to repeat itself, so after Imam al-Māwardī released his realistic vision justifying Islamic governance in his book Al-Aḥkām al-Ṣulṭāniyyah, Imam al-Juwaynī came out with his own book, Ghiyāth al-Umam fī Tiyāth al-Ẓulam, with a hypothetical mindset, to put in place the foundations and objectives of the sharīꜥah for Islamic governance, leadership of the ummah, and strategies to deal with the absence of a mujtahid and leader (imām). Using al-Juwaynī’s book, this research aims to demonstrate his unique contributions to this vast subject, which was, and still is, slippery territory both theoretically and practically. This research uses analytical method to explain the objectives and principles of Islamic governance as explained by Imam al-Juwaynī in Ghiyāth al-Umam within the framework of maqāṣid al-sharīah. This study finds that his thought in this field has strong correlation with the concept of maqāṣid al-sharīah and can enrich our understanding about Islamic governance.
Keywords: Islamic Governance, maqāṣid al-sharīah, al-Juwainī, imāmah, government.
Abstrak
Dalam realiti percanggahan visi dan perspektif, penglihatan menjadi keruh, asas-asas menjadi goyah, dan asap menguasai semuanya. Sejarah cenderung untuk berulang, maka selepas Imam al-Māwardī mengeluarkan pandangannya yang realistik yang membenarkan pemerintahan Islam dalam bukunya Al-Aḥkām al-Ṣulṭāniyyah, Imam al-Juwaynī keluar dengan kitabnya sendiri, Ghiyāth al-Umam fī Tiyāth al-Ẓulam, dengan satu pemikiran hipotesis, untuk meletakkan asas-asas dan matlamat syariah bagi tadbir urus Islam, kepimpinan ummah, dan strategi untuk menangani ketiadaan mujtahid dan pemimpin (imām). Dengan menggunakan buku al-Juwaynī, penyelidikan ini bertujuan untuk menunjukkan sumbangan uniknya dalam subjek yang luas ini, yang, dan masih, adalah wilayah yang licin baik secara teoritis dan praktikal. Penyelidikan ini menggunakan kaedah analisis untuk menjelaskan objektif dan prinsip pemerintahan Islam seperti yang dijelaskan oleh Imam al-Juwaynī dalam Ghiyāth al-Umam dalam kerangka maqāṣid al-sharīah. Kajian ini mendapati bahawa pemikirannya dalam bidang ini mempunyai hubungan yang kuat dengan konsep maqāṣid al-sharīah dan dapat memperkaya pemahaman kita tentang pemerintahan Islam.

Authors: Hamid Kashif , Ghafoor Muhammad Mudasar , Saeed Muhammad Yasir
Published: August 2020

Emerging markets and volatility spillover effects remained a highly focused area in the field of financial economics. Therefore, we have empirically testified the volatility spillover effects between markets of emerging economies i.e Pakistan, China, Bangladesh, and India during the period from 1st January 2000 to 31st December 2015. We used Multivariate GARCH and causality models to identify the spillover effects. It is concluded that there exists significant evidence of spillover effect from the market of Pakistan to India, India to China and from China to Pakistan. However, the larger negative shift in the volatility occurs more frequently than positive shocks. Hence it is concluded that the impact of own spillovers of the markets is much higher than the impact of cross-market spillovers during this period.

Authors: Allah Nawaz  , Khan Irfan Ullah
Published: August 2020

E-Learning [EL] systems are developed by professionals but used by those belonging to one or another field and not the computer as subject. Given this, EL has to be developed within a scenario of technical, human and social aspects of the environment wherein the new system is about to operate. Which technologies are available and how they are perceived determines the development and use processes however, this relationship is mediated by users’ digital literacy issues and beliefs about the nature and role of ICTs in education? This is therefore incumbent upon developers and HEI-management to start with a broader picture of EL projects and make technical, human, social and organizational arrangements to develop and integrate the new system within the existing work environment making it supportive to prospected users. This paper develops theoretical model of theory of EL development and use in higher education in the background of developing states.

Authors: Oben Julius , Bigoga Jude , Takuissu Guy , Leke Rose
Published: August 2020

Background: COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).  Despite the World Health Organization’s publication of different measures to curb the spread of COVID-19, new cases are reported daily.  These protective control measures put in place assumed that transmission of COVID-19 was mediated essentially through droplets released from the nasal and respiratory secretions of infected persons.  Recent scientific evidence however puts forward the occurrence and shedding of active COVID-19 virus in stools of infected persons.  The present study tested the acceptability of an improved version of the ‘Yellow soup’ which contains ingredients/spices with known antibacterial/antiviral properties.Methods: Star Yellow was made by using a palm oil/limestone base to which was added spices /ingredients rich in zinc and known for their antiviral/antibacterial activity. Sensory evaluation of the resulting mixture was done by a taste panel comprising habitual eaters of ‘Yellow soup’ using a hedonic scale of 1 to 5.Results and Conclusion: Sensory assessment of Star Yellow showed a mean acceptability of 77.4% compared to 54.8% obtained for the commercial Yellow Soup served in restaurants. This indicates the acceptable taste of Star Yellow and opens up potential new avenues of research in the control of SARS-CoV-2 virus transmission via feces.Keywords: Yellow soup, COVID-19, feces, gastrointestinal tract, zinc, RNA replication.
Technique for flowrate calculation of cryogenic two-phase flows in Venturi flowmeters without separation
Authors: Arkharov I.A. , Kakorin I.D.
Published: August 2020

A technique for calculating the flowrate of cryogenic two-phase flows in separationless flowmeters based on a venturi is proposed. The technique takes into account the equation of state of the two-phase medium, that is changes in density, mass vapour quality and temperature of cryogens two-phase flows against pressure in the venturi. It is shown that without an accounting of the flow parameters evolution, an additional flowrate error appears and therefore it is impossible to correctly determine the sensitivity and measurement range of the flowmeter. The most optimal measurement range of the pressure drop is chosen as well as a method of the flowrate measuring by the temperature difference across the venturi is proposed. The problem of determining the flowrate of two-phase cryogenic flows is topical for accelerator, aerospace and gas-transport engineering.

Competition in sports field leasing is quite fast these days, making sports field managers improve facilities and provide competitive prices to attract sports field tenants. However, this progress was not accompanied by advances in technology so that sports field managers still had to do the manual method for field operations and promotion. On the side of the tenants of the sports field also still have to go to the sports field to find out the availability of schedules, facilities, and prices offered. Then many tenants who have an interest in exercising more than one branch of sport, therefore researchers use the concept of a marketplace that can bring together the managers of sports fields with field tenants in one container. In the application development process, it is done by using the agile method application development method because in its development it can be possible to collaborate and correct each other among team members to increase the customer satisfaction ratio. The application implementation uses the Laravel framework, PHP for programming language, and the MySQL for Database Management System. The results of the study can be concluded that the use of the marketplace concept can bring together prospective field tenants with many field managers and the ease of finding a sports field following the wishes of tenants by selecting the category of field, price and closest location and the manager of the sports field can promote the sports field by registering the field.

Published: August 2020

Em tempos de Covid-19, a quantidade de informação a respeito do vírus ou da doença, seja verdadeira ou falsa, sofreu um aumento exorbitante. Nisto, várias recomendações, cartilhas, conceitos, ideias e tutoriais, seja sobre o vírus ou qualquer outra coisa associada ao momento de pandemia, foram difundidos e aderidos de maneira extremamente rápida. Concomitante a isso, o objetivo do presente estudo visa responder quais os possíveis motivos que proporcionam este alto volume e adesão de informações — ideias, propostas comportamentais, recomendações e informativos gerais — a respeito do vírus e/ou da doença ou algo associado a ambos. Desta forma, utilizamos o conceito de meme introduzido pelo etólogo e biólogo evolutivo Richard Dawkins e ampliado pela psicóloga Susan BlackMore, assim como, recomendações dos órgãos de saúde, artigos e websites que fizessem alusão ao novo coronavírus. Para o biólogo, um meme pode ser entendido como uma unidade replicadora análoga ao gene no âmbito cultural. Tal conceito foi desenvolvido por Dawkins como uma tentativa de tornar possível o estudo da cultura e da transmissão cultural, assim como a disseminação de informações através do processo de seleção natural. Nesse caso, da seleção natural de memes.

Current study investigates experimentally the scour around vertical pier of octagonal cross section with pier modification such as newly proposed octagonal hooked collar is explored, in steady uniform state, under clear water condition. The results of pier scour without any modification were used as a reference to compute the efficiency of hooked collar provision around octagonal pier. The results show that by increasing the hooked collar width up to 2.5 Wp reduced maximum scour depth significantly. However, the experimental investigation revealed that the best combination to be with a hooked collar width of 2.5 Wp, having sidewall height 0.45 Wp. The best combination minimized around 73.3 % of scour hole depth, compared to octagonal pier without any modification. Using experimental results, a new equation is proposed to predict the scour depth around a bridge pier fitted with hooked collar. Moreover, a relation was developed for maximum scour depth and scour hole volume. Results indicate that the scour hole volume around a bridge pier increases quadratically with maximum scour depth.

Frá skiptisögn til ósamhverfrar aukafallssagnar: Um 'líka' í fornu máli
Authors: Sigurðsson Einar Freyr , van der Feest Viðarsson Heimir
Published: August 2020

In Modern Icelandic the verb líka ‘like’ occurs with a subject in the dative case and an object in the nominative case. It has been argued that this was also the case in Old Icelandic. In this paper we argue that in contrast to Modern Icelandic, the nominative argument of líka could also constitute the subject during the Old Icelandic period and the dative argument the object. More specifically, we maintain that the verb líka was an alternating (or symmetric) verb where the nominative and the dative argument could raise to the subject position, whereas in Modern Icelandic only the dative is able to raise to the subject position. In other words, we argue that a change in the argument structure of the verb has taken place such that líka has changed from being an alternating (symmetric) verb to an asymmetric oblique subject verb. The main argument that is used to substantiate this claim comes from control infinitives in Old Icelandic, taking on the form in (i):

(i) girntiz meirr at líka einum guði en mönnum
desired.mid more to PRO.nom like.inf alone.dat god.dat than men.dat
‘(He) desired more to please God alone than men.’ (Æv 150.15)

Based on a generative analysis of syntactic structure, we present evidence that reveals that the dative argument functions syntactically as the object, in addition to discussing other potential evidence based on word order. When the nominative argument is the subject, the meaning of 'líka' is sometimes closer to that of English 'please' than 'like'. We also discuss how this might be accounted for.
Asnaleg íslensk nýyrði?

In this article, I discuss common ideas that speakers of Icelandic have about neologisms and their formation. Based on public discussions, we can assume that speakers find
accuracy and transparency to be the most important features of a neologism. At the same time, they need to be as short as possible. These requirements often conflict.
Additionally, neologisms should fit into the Icelandic grammatical and phonological system, be well suited to use as part of compound words and other word formations
accomplished through derivation. Finally, speakers tend to be more positive towards neologisms that are formed by using Icelandic roots than using adaptations of words
borrowed from other languages.

Adapting to Climate Change at the National Level in St. Vincent and the Grenadines
Authors: Lewis Clint , Su Ming-Chien
Published: August 2020

Small island developing states (SIDS) are distinctively more vulnerable to the impacts of climate change than other developing countries. The focus of this paper is the Caribbean region that is described as one of the most vulnerable regions in the world and highly affected by the impacts of climate change. This paper applies a case-study approach and focuses on the island of St. Vincent and the Grenadines (SVG). With limited efforts to understand the adaptation, vulnerabilities, and challenges at the national level in these SIDS, this paper helps to fill this gap and has two main aims. First, it identifies SVG’s main focus on climate change adaptation. Second, it identifies the barriers to climate change adaptation in SVG. To fulfil the aims of this paper, content analysis, and semi-structured interviews with 32 stakeholders from the public and private sector were applied. This paper finds that SVG is mainly adapting to changes in hurricane, rainfall, drought, and soil and coastal erosion patterns. It also finds that many factors are limiting national-level adaptation. The three main reported barriers are a lack of financial, human resources, and technical capacity. These findings are important for the government of SVG and international donors and agencies. This will help them to identify and fill the gaps in their adaptation actions and prioritising finance. This paper’s findings also highlight the importance of mainstreaming climate change adaptation in sectoral plans and work programs and improving SVG’s access to international climate change adaptation funding.
Examining Solid Waste Practices and Littering at the University of the West Indies, St. Augustine Campus
Authors: Jameer Vaughn-Xavier , Mallian Ambika , Halfhide Trina
Published: August 2020

Littering is a rampant problem and rooted in human behaviour. This study aims to record, categorise, and examine spatial patterns between pieces of litter and trash and recycling bins across the University of the West Indies, St. Augustine Campus. The geographic location of pieces of litter and bins (trash and recycling) were recorded and georeferenced to a campus base-map. A total of 10, 889 pieces of litter were recorded over the 7-day survey. The majority of litter was plastic (47.6%) and cigarettes (24.1%). The litter on campus was not evenly distributed. The kernel density estimation demonstrated that there was an obvious hotspot in the south-east of campus at the student activity centre (SAC), where there were more than 5 pieces of litter per sq. meter. The total of 182 bins was recorded and the mean distance between bins was 13.0 meters. Most of the bins were clustered in the southwest end of the hotspot, near the SAC. In addition, there were no recycling bins placed in this location. A recycling bin should be located in the SAC, as there are the most littering offenses, and recycling success with plastic items can be improved. Using a uniform colour for trash bins may increase proper solid waste disposal and reduce littering.
Building Resilient Caribbean Small-Island Developing States Through Community-Based Disaster Risk Perceptions
Authors: Thongs Gabrielle , Griffith Kerri
Published: August 2020

The Caribbean’s susceptibility to natural disasters was reinforced after the multi-hazard impact of the 2017 hurricane season. Multiple disasters have caused severe physical, social, and economic loss in the region since the Caribbean’s disaster susceptibility encompasses more than physical exposure. These susceptibilities, however, have not translated into heightened disaster data collection or risk assessments. The fact is that the region currently lacks a standardized methodology to assess risk. In response to this absence, the ‘Caribbean Risk Information Tool’ (CRIT) was developed by the International Federation of Red Cross and Red Crescent Societies. Since assessing risk is a key aspect to increase resilience, this study seeks to investigate the usefulness of this community-based risk information tool, within the Caribbean context. The paper accordingly aims to examine the role of community-based and local-level approaches using a small island developing state case study. The present results are significant in at least three major respects. From the information collected through the CRIT in the Sangre Grande regional corporation, it was possible to identify the peak months of disasters, the hazards with the highest impact in the regional corporation, the most susceptible communities, the communities that are in immediate danger or crisis, as well as the natural and man-made triggers of the most impactful disasters. The continuous collection of this qualitative data hopes to, therefore, consistently inform mitigation and resilience strategies in the Caribbean.
The Regional Disability Index and Strengthening Resilience of Persons with Disabilities in the Anglophone Caribbean
Authors: Morris Floyd
Published: August 2020

In 2019, the University of the West Indies Centre for Disability Studies (UWICDS) released the results of the first Regional Disability Index (RDI). The RDI was developed with the primary aim to track and rank countries within the Caribbean in terms of their efforts to implement the provisions of the Convention on the Rights of Persons with Disabilities (CRPD) and by extension, the Sustainable Development Goals (SDGs). The RDI used a quantitative methodological framework employing a survey among government and non-governmental organizations catering to persons with disabilities in the Anglophone Caribbean to capture the data. In this paper, this researcher conducts an assessment of the major findings of the RDI in the context of building resilience among persons with disabilities in certain fundamental areas of Caribbean life. Findings relating to legislative protection, education, employment, public transportation, health care, and access to information are highlighted. The RDI, among other things, revealed that St. Vincent and the Grenadines is the top country in the Anglophone Caribbean in terms of their efforts to implement programmes and policies for persons with disabilities. We compare and contrast the findings regionally to that which is taking place in the global landscape for persons with disabilities.
Prevalence of Temporomandibular Joint Disorders and its Association with Para Functional Habits in the Patients Attending Tertiary Care Hospital
Authors: Chaulagain Rajib , Maharjan Anjana
Published: August 2020

Background: Temporo-mandibular disorders is a collective term used to describe problems involving muscles of mastication and temporomandibular joint. The study aimed to evaluate the prevalence of temporo-mandibular disorders and its association with parafunctional habits in patients visiting department of dentistry, Patan Academy of Health Sciences.Methods: A cross-sectional study was carried out among 213 patients coming to Patan Academy of Health Sciences. A screening questionnaire recommended by American Association of Orofacial Pain was used to determine the signs and symptoms of temporo-mandibular disorders.Results: The prevalence of temporomandibular disorders was 31.9 %. The three most common parafunctional habits were chewing gums (32.4 %), mouth breathing (19.7 %) and biting of objects (14.6 %) respectively. Statistically significant association was found between nail biting, grinding of teeth, biting of lips and objects and mouth breathing with signs and symptoms of temporomandibular disorders (p<0.05). Among the signs and symptoms of temporomandibular disorders, getting headaches, neck pain or toothaches often was the most frequent signs of temporomandibular disorders (n=105, 49.3 %). Feeling of recent change in bite was the second most frequent sign reported by 82 participants (38.5 %).Conclusions: The parafunctional habits between nail biting, grinding of teeth, biting of lips and objects and mouth breathing have statistically significant association with signs and symptoms of temporomandibular disorders. Keywords: AAOP; parafunctional habits; prevalence; TMDs.
Compuestos Fitoquímicos Dirigidos al Bloqueo de la Polimerasa Viral del SARS-CoV-2 Causante del COVID-19: un Análisis Comparativo de Funciones de Puntuación para Acoplamientos con Interés Biomédico

Published: August 2020

La pandemia mundial del COVID-19 causada por el SARS-CoV-2 ha hecho necesario buscar alternativas de tratamiento. La OMS ha recomendado el fármaco aprobado por la FDA Remdesivir dirigido a la RNA polimerasa viral. Adicionalmente, se han evaluado computacionalmente compuestos naturales con propiedades antivirales. Sin embargo, estos estudios se centran en el uso de la función de puntuación del algoritmo AutoDock Vina (ADV) para predecir los candidatos. Aquí proponemos evaluar los fitoquímicos Piperina_ID_638024, EPGG_ID_65064, Curcumina_ID_969516, y Capsaicina_ID_1548943 frente a la RNA polimerasa del SARS-CoV-2 (PDB_ID_6NUR), usando Remdesivir_ID_121304016 como control, mediante análisis computacional, comparativo y multivariado de las funciones de puntuación ADV, PLANTS, MolDock, Rerank y DockT considerando la solubilidad de ligandos e hidrofobicidad de las cavidades implicadas en las interacciones, para aumentar la precisión en la predicción de los mejores acoplamientos de los compuestos naturales frente al COVID-19. Encontramos que 4/5 de las funciones de puntuación exceptuando ADV predijeron el acoplamiento termodinámicamente más favorable con Piperina, superando a Remdesivir. También observamos que las calificaciones de PLANTS, ADV y DockT se afectan por la solubilidad del ligando e hidrofobicidad de cavidades. Bajo las condiciones de este estudio concluimos que los algoritmos MolDock y Rerank son más adecuados para el cribado rápido y la reorganización de acoplamientos, cuando se trabaje con ligandos solubles (Rp = 0.70 para ambos), indistintamente de su polaridad, y dirigidos a cavidades hidrofóbicas de la RNA polimerasa del SARS-CoV-2 (Rp = 0.95 y Rp = 0.90, respectivamente), especialmente para los enfoques computacionales en el contexto de la investigación de fármacos frente al COVID-19.
