Authors: Akinbohun Folake , Akinbohun Ambrose , Daniel Adekunle , Ojajuni Oghenerukevwe Elohor
Published: September 2020

Head and neck cancers (HNC) are indicated when cells grow abnormally.  The incidence of HNC is on the increase owing to several factors. There is often late presentation that can result in loss of lives (mortality) especially in Africa due to paucity of specialists. These challenges prompted the development of a stacked ensemble model for diagnosis of HNC to facilitate prompt referral.  The data were collected which consists of 1473 instances with 18 features.   Information Gain was used for selecting important features and three supervised learning algorithms were deployed for the base learners: Decision Tree (C4.5), K-Nearest Neighbors and Naïve Bayes. The predictions of the base learners were combined and passed to meta learners: Logistic Model Tree (LMT). The result showed that Information Gain method with stacked LMTwas 95.11%. It was deduced that both Information Gain with stacked MLR produced higher accuracy that the base learners’ results. Hence, this stacked model can be used for diagnosis of HNC in healthcare systems.

Authors: Amadi Azubuike Hope , Ola Victor D. , Ayoola John O.
Published: September 2020

Since the discovery of Crude Oil in 1875, the Petroleum Industry has gradually improved in value due to the series of valuable products gotten from crude oil. The significant impact of crude oil as a source of energy has made exportation and importation of this mineral a lucrative business around the world, having turned to be the major source of revenue for most producing countries. Crude oil has contributed to about 80% of Nigerian Government revenue and foreign exchange since 1958, making it a key player in the economic plan of the country. Its importance in Nigeria has made the Legislature introduce lots of policies and laws governing the Oil and Gas business in the country. However, Nigerians with different views over the years have clamored for an improvement of these policies to enable the benefits of Her resources fairly get to the grassroots, producing communities and states while improving foreign investment policies in the country. These demands led to the introduction of the Petroleum Industry Bill (PIB) in the year 2000. This research work attempts to review and offer recommendations for improvements to avoid future litigations, violence, conflicts, and industry fragility. This work will also elaborate on different steps taken by the Nigerian Government over the years to implement this bill, challenges faced by the Government and International Oil Companies (IOCs), Government and its citizens, and anomalies seen in the bill up till status quo.

Sailing into Wind Is Explained by Newtonian Mechanics Based on The Mass-Flow Rate
Authors: Landell-Mills Nicholas
Published: September 2020

The physics of sailing into the wind can be explained using Newtonian mechanics based on the mass flow rate. The sail re-directs a mass of air each second (m/dt) towards the boat’s stern, at a relative velocity (dv) that depends on the apparent wind. The re-directed airflows push against the otherwise undisturbed apparent wind to create a backward force (i.e. Force = ma = m/dt × dv). The reaction generates an equal and opposite forward force that pushes the boat ahead.

There are two separate airflows as the sail re-directs the wind on the sail’s windward and leeward sides. The leeward airflow relies on the Coanda effect and is sensitive to the sail’s angle-of-attack (AOA). This approach provides new and valuable insights on sailing into the wind. However, it is a very different approach compared to the current explanations of sailing into the wind, described by fluid mechanics and vector-based solutions.

Margaret Atwood: A Sound Ecologist
Authors: Baranwal Dr. Ratnesh
Published: September 2020

This paper is an attempt to explore the ecological issues in Margaret Atwood’s novels. She happens to raise her voices against the demolition of the forests, advocating very strongly to pay attention to ecological principles for the preservation of the environment for the future generation. She tends to express her deep sense of anxiety over the ecological issues as depicted in The Handmaid’s Tale (1985) and again in the stories and fables of Wilderness Tips (1991) and Good Bones (1992). Her novel – Surfacing (1972) begins and ends with the forest starting like a detective story. Her most significant search-operation begins when she happens to dive into the lake, looking for the Indian rock paintings recorded in her father’s drawings in chapter 17 of the novel. Environment or wilderness strongly figures out in her fabric of Canadian identity. It has multiple functions : as a marker of geological location, as a spatial metaphor and as a popular cultural myth of Canada. Geographically, it is defined as ‘wild uncultivated land’. She rediscovers the White English – Canadian construction of identity, charting a distinctive New World positioning in relation to history, geography and culture suggestive of continuity between immigration narratives and a contemporary awareness of psychic location. Environment holds a very significant place in her portrayal of Canadian identity. She personally holds a bitter experience of Colonialism and its outcome on Canada and Canadians in the post-colonial era. Her fiction comprises of several post-colonial themes such as survival, hybridization, isolation, hegemony, displacement, loss of identity, banishment, multiculturalism, homelessness, colonization of the mind and of the natural world. Thus this paper seeks to analyze the different shades of ecology and ecocriticism exploring the organic unity between the man and the environment. This theory has gained a great importance since last few years. The ecological balance between the human and environment is shattered. People have deviated from their moral duties towards nature. Thus as a sound observer of ecology, she finds out the misuse and colonization of the natural world.
In Trail of the Clash of two Civilizations
Authors: Sirohi Rashmi
Published: September 2020

Nature is full of mysteries which compel one to explore the hidden passages. The passionate urge might take a traveller into the deepest corners of forgotten lands which have truths to be unraveled. Each and every space dynamics has its own temporality and ideological framework which shapes the entire course of ones ideas. The paper will talk about the travelling account of Che Guevara captured in his memoir The Motorcycle Diaries. The book traces the early travels of this Marxist revolutionary. The idea behind is to mark the curvature of topological transformation and its impact on the ideological framework of a person. The paper will explore the interconnections and impact of different spaces encountered during a travel and the nature of discourse which develops during such explorations. Ideas have a disposition to travel with the moving discourse where the architectural domain shapes the outline of the traveller’s thought process. Here Che Guevara’s trip through South America will portray the flow of ideas through different spaces formulating the base for his revolutionary ideas. Through the account of Francisco Pizarro during the conquest of Incan civilization and through the impact of this event on the civilization as a collective whole, the paper will attempt to analyze the ethical curvature of two distinct civilizations, namely the Incan and the Christian Imperial West. The conquest of the South American continent and the consequent clash was cataclysmic, as the socio-economic subversion is still embedded almost non- retrievably deep in terms of its collateral. The paper will include “Heights of Machu Picchu” by Pablo Neruda which again is set during his travelling account to Machu Picchu, which is the marker of a lost civilization where the distorted architecture echoes the richness and the loss at the same time.
Achievers of Freedom in the Select Novels of Rabindranath Tagore
Authors: Nanda Dr. Silima , Gandhi Dr. Hanny
Published: September 2020

My article analyses the achievers of freedom in the select novels of Tagore who dedicate themselves to the higher ideals of love, self-knowledge and truth. They represent Tagore’s vision of   freedom where man-made shackles fail to trap the Universal Man. Tagore’s idea of freedom begins with the personal and ends with the universal. The different characters in his novels reach different levels of freedom in their search. They struggle as they are faced with challenges, but they all grow. The true achievers analyzed in the select novels of Tagore are the emancipated characters who possess the innate strength to confront the outward challenges of the society and achieve ultimate freedom by transcending from the lower self through love, knowledge and creativity.

Authors: PAN Xiaoquan , SHAO Huijuan
Published: September 2020

Based on the theories of self-directed learning, technology acceptance model (TAM) and the theory of planned behavior (TPB), this study constructed a model of predictors of English as a Foreign Language (EFL) students’ technology-based self-directed learning. Through a questionnaire survey of 386 EFL students from a Chinese university and structural equation model analysis, this study intended to identify the factors that influence the students’ use of technology for language learning and the relationship between these factors. The results revealed that attitude towards technology use, perceived usefulness and technological facilitating conditions are the dominant predictors of technology-based self-directed learning, whereas technological complexity had no direct impact on technology-based self-directed learning, but played an intermediary role through attitude towards technology use. Subjective norms had less predicative power on technology-based self-directed learning. The findings suggest improving students’ perception of the usefulness of technology in learning, enhancing students’ attitude towards technology use and constructing convenient technological facilitating conditions

Lexical Metaphor as Judgment: Attitudinal positioning of editorial writers in business newspapers
Authors: Katajamäki Heli Susanna , Koskela Merja
Published: September 2020

Drawing on appraisal theory, this paper aims to analyze how the attitudinal positioning of writers of the editorials of business newspapers can be construed by means of lexical metaphors. The focus is on judgment, the evaluation of human actors, because it indicates the subjective presence of a writer. Based on a dataset o3f 32 editorials of two Finnish business newspapers, the results show that the lexical metaphors used during assessments are mostly dead metaphors, representing the source domains of competition and sports, humans and animals, and war, battle, and violence. The most common targets of judgment are institutional actors that are described by the meanings of capacity, tenacity, and propriety. Economic actors are mostly evaluated positively while political actors are mostly evaluated negatively. Cases where economic actors are evaluated negatively and where individual persons are mentioned are unusual but do arise. In general, judgments in editorials reflect the shared values and ideological beliefs of the papers and their readers. Lexical metaphors offer a subtle way of praising and criticizing institutions and individual people, which makes them an important way of communicating as expected in a discourse community.
“I’m not a kid anymore!” Towards a teen-centric approach of online privacy management
Authors: Koinig Isabell
Published: September 2020

The youth constitutes the largest user base of social media networks. While this generation has grown up in a digitally immersed environment, they are still not immune to the dangers the online space bears. Hence, maintaining their privacy is paramount. The present article presents a theoretical contribution, that is based on a review of relevant articles. It sets out to investigate the importance adolescents attribute to online privacy, which is likely to influence their willingness to disclose data. In line with a “new privacy paradox”, information disclosure is seen as unavoidable, given the centrality of social networks to adolescents’ lives. This goes hand in hand with individual privacy management. As individuals often lack knowledge as to how to protect their privacy, it is essential to educate the youth about their possibilities, equipping them with agency and self-responsibilization. This corresponds with a teen-centric approach to privacy as proposed by the TOSS framework.
Education with Digital Culture: Shifting the Paradigms of Prospective Knowledge by Mediatization
Authors: Marci-Boehncke Gudrun , Rath Matthias
Published: September 2020

This article presents the paradigm shift, especially in school education, under the conditions of current mediatization, whereby we understand education initially as a communicative system that is dedicated to the acquisition of new and future relevant knowledge in lifelong processes of appropriation. To this end, educational institutions demand an educational language that screens out those who cannot serve that linguistic register. Arguing with regard to Rawls and Nussbaum, we present this selection mechanism under the conditions of current mediatization as both ideologically outdated and practically reducible and refer to current models of professionalization of teachers and international competency frameworks for digital media education.

Published: September 2020

The coastal area in the Son Tra – Tam Ky region have various kinds of sand dunes: (1) embryo dunes; (2) foredunes; (3) yellow dunes; (4) gray dunes; (5) white dunes; (6) brown dunes. These sand dunes play an important role in maintaining biodiversity, minimizing the damage of natural hazards and tourism development. In last decade, the sand dunes in Son Tra (Da Nang) - Tam Ky (Quang Nam) is strongly influenced by urbanization and tourism development. Different resorts have been built along the beaches, narrowing protective forests on the sand dunes. It does not only reduce the value of cultural ecosystem services; but also, the ability to regulate natural disasters and air pollution. Therefore, the study aims to assess the unbalance in sand dune ecosystems service supply in Son Tra - Tam Ky area. Methods used in the study include: remote sensing and GIS, collecting statistics and specialist interviews. The results showed a clear differentiation in the potential of the ecosystem services in different sand dune types. Lastly, the study analyzed the values of sand dune ecosystem services in Son Tra - Cua Dai part; to assess differences in planning and development policies between the coastal zones of Quang Nam and Da Nang.

Published: September 2020

This paper approaches the ratio image method to extract the exposed rock information from the Landsat 8 OLI/TIRS satellite image (2019) according to the object orientation classification. Combining automatic interpretation and interpretation through threshold of image index values according to interpretation key the object orientation classification to separate soil object containing exposed rock and no exposed rock in Thua Thien Hue province. Using the Topsoil Grain Size Index (TGSI), the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Built-up Index (NDBI) and other related analytical problems have identified 40 exposed rock storage areas in the study area. The results have been verified in the field and the Kappa index is 85.10%.
