Authors: Abbas Abbas
Published: January 2021

This article aims at describing the social life of the American people in several places that made the adventures of John Steinbeck as the author of the novel Travels with Charley in Search of America around the 1960s. American people’s lives are a part of world civilizations that literary readers need to know. This adventure was preceded by an author’s trip in New York City, then to California, Connecticut, Rhode Island, New Hampshire, Massachusetts, Maine, New Jersey, Saint Lawrence, Quebec, Niagara Falls, Ohio, Chicago, Illinois, Michigan, North Dakota, the Rocky Mountains, Washington, the West Coast, Oregon, Arizona, New Mexico, Texas, New Orleans, Salinas, and again ended in New York. In processing research data, the writer uses one of the methods of literary research, namely the Dynamic Structural Approach which emphasizes the study of the intrinsic elements of literary work and the involvement of the author in his work. The intrinsic elements emphasized in this study are the physical and social settings. The research data were obtained from the results of a literature study which were then explained descriptively. The writer found a number of descriptions of the social life of the American people in the 1960s, namely the life of the city, the situation of the inland people, and ethnic discrimination. The people of the city are busy taking care of their profession and competing for careers, inland people living naturally without competing ambitions, and black African Americans have not enjoyed the progress achieved by the Americans. The description of American society related to the fictional story is divided by region, namely east, north, middle, west, and south. The social condition in the eastern region is dominated by beaches and mountains, and is engaged in business, commerce, industry, and agriculture. The comfortable landscape in the northern region spends the people time as breeders and farmers. The natural condition in the middle region of American is very suitable for agriculture, plantations, and animal husbandry. Many people in the western American region facing the Pacific Ocean become fishermen. The natural conditions from the plains and valleys to the hills make the southern region suitable for plantation land.

Symbolism of Water in Classic and Modern Arabic Literature
Authors: Hamad Mohammad
Published: January 2021

Water in Arabic literature has literal and symbolic meanings. Water is one of the four elements in Greek mythology; life would be impossible without water and it is a synonym for life; life originated in water. Springs, wells, rain, seas, snow, and swamps are all associated with water. Each form of water may take on a different manifestation of the original from which it comes about. Arabic literature employs the element of water in poetry, the short story, and the novel. We find it in titles of poems: Unshudat al-matar (Hymn of the Rain) and Waj’ al-ma’ (The Pain of Water); and novels: Dhakirat al-ma’ (The Memory of Water); Taht al-matar (Under the Rain); Matar huzayran (June Rain); Al-Bahr khalf al-sata’ir (The Seas Behind the Curtains); Rahil al-bahr (Departure of the Sea); and many others. This study aims to answer the following questions: How does the element of water manifest in Arabic literature? What are the semantics and symbolism of the different forms of water in the literary imaginary?
The study refers to six different significations for water in classical and modern Arabic literature: water as synonymous with life, purity and the revelation of truth, separation and death, fertility and sex, land and homeland, and talent and creativity.
Non-Wh Internal and External Topics in Classical Chinese and Their Similarity to Equivalent Constructions in Modern Mandarin
Authors: Wang Aiqing
Published: January 2021

In this paper I argue that non-wh internal and external topics in Classical Chinese can be analysed in parallel with their counterparts in modern Mandarin. I first scrutinise pronoun fronting in the context of negation in Classical Chinese, and propound that it is on a par with object preposing in modern Mandarin that is argued to be internal topics (Paul 2002). I then discuss non-interrogative elements base-generated and moved to the CP domain and illustrate their topical properties. Base-generated topics in Classical Chinese are Aboutness topics which permit DPs exclusively. In terms of moved external topics, they are constituted of preposed objects and preposed predicates: the former allow DPs and TPs, whereas the latter allow DPs and AdjPs. Moreover, moved topics can be further divided into Hanging Topics and Left Dislocation Topics, similar to those in modern Mandarin.
War on Drugs: The Readability and Comprehensibility of Illegal Drug Awareness Campaign Brochures
Authors: Vergara Fermina , Lintao Rachelle
Published: January 2021

Information communicated and produced by the government is essentially fundamental as the government is set and deemed as a reliable and a credible source of information. This study assessed the readability, comprehensibility, and document design of two brochures on prohibited drugs awareness, which were produced and distributed by the Dangerous Drugs Board (DDB), a government agency that is responsible in instituting policies about the use of illegal drugs in the Philippines. Using both qualitative and quantitative methods, a total number of 120 participants comprised of students, those employed, the unemployed, and drug patients from a rehabilitation center answered two 10-item multiple choice questionnaires and Likert scales to assess and evaluate the comprehensibility and document design of the two brochures. Using the Coh-Metrix tool to analyze the readability of the two brochures, results showed that the two existing brochures were not that readable with the huge discrepancy of the readability levels of the docments against the 9-10 normative values of the reading tool utilized.  The results of the participants’ scores which were categorized as instructional or assisted level exhibited that the two brochures were not that comprehensible. Lastly, it was found that the designs of the documents were poor as some violations like small font size, pixelated pictures, and non-observance of color schemes were present. This paper argues that government agencies should produce information brochures that are patterned to the standards of Plain Language Movement in order to help the lay people grasp important information such as drug awareness.
Colonial vs Colonized Counter-Hegemonies: Two Vistas of Moroccan Educational Models
Authors: Bouyahya Driss
Published: January 2021

Both France and Spain used schooling as a vehicle in service of colonization during the Protectorate era in Morocco, whereas Moroccans retaliated with counter-hegemonic tools to resist and interrogate imposed educational models in order to implement their oppositional agendas. Thus, the paper is threefold: it attempts to revisit and sketch out both colonial policies in education with their ramifications, while outlining and analyzing their strengths and limitations. The study also seeks to investigate how Moroccans establish resistance movements to react to the newly-imposed colonial hegemonies, such as free schools and reformed traditional Qur’anic schools (Msids), discussing their goals, structures, success and failure. Finally, the paper explores colonial education as a site of interaction or “contact zones” between French and Spanish colonizers and elite Moroccan Muslims and Nationalists who sought to counter the processes of acculturation, marginalization and subalternization. The study covers the Moroccan schooling system from 1912 to 1956. The study dwelled on the congruity of education as an ideological apparatus to shape identity and/or dominate in a battlefield over power between the Protectorate powers and the Moroccan nationalists, who made use of different discourses as an instrument of power. This essay unravels some conclusions that both French and Spanish Protectorates utilized different vistas to establish and sustain their hegemonies through education and instruction, such as Franco-Berber schools and Spanish-Arab/Spanish-Jewish schools respectively. While, Moroccan Muslims and nationalists countered the former hegemonies through creating a free-school system and reforming traditional Qur´anic schools.
Slavery and power in Behn’s Social Context; A New Historicist Reading of Oroonoko
Authors: Poorghorban Younes
Published: January 2021

The aim of this article is to illustrate how power works within Behn’s Oroonoko in light of New Historicism. Behn’s standpoint concerning slavery is quite unsettling, many arguments have been proposed concerning this issue. It is intended to shed light on how slavery is perceived for Behn and through her outlook, it becomes possible to illustrate how English colonialising power acts in opposition to whatever that aims to subvert it. Discourse is a vehicle of power and in this paper, many discourses are analysed to depict the essence of power. Language through discourses has managed to control and reproduce what is known as the truth. By shaping the truth in alliance to the dominant power it becomes possible to subvert and contain the opposing resistance. This article illuminates how truth is shaped for the subjects of power (mainly Oroonoko and his Wife) by the proposed discourses of the narrator who is also considered as Behn herself.
Supervisory Support Received by EFL Student Teachers during Practicum: The Missing Link
Authors: Al-Jaro Morshed , Asmawi Adelina , Abdul-Ghafour Abdul-Qader Khleel
Published: January 2021

This study investigates the role of supervisory support for assisting the EFL student teachers to perform better during practicum. It also aims at identifying the barriers of effective supervision during teaching practicum. The study adopts the qualitative research design using a multiple case study. Semi-structured interviews are developed to collect data from four student teachers and their supervisors during their teaching practices at local secondary schools in Yemen. Four emerging themes are developed from the thematic analysis of the data including the supervisory support on lesson planning, teaching strategies, classroom management and the number of observations. The findings reveal that the participating student teachers received insufficient support and guidance from their panel supervisors which limit their pedagogical practices during practicum. The findings also highlight some barriers to effective supervision due to some restrictions. The study provides practical implications for EFL teacher education program administrators and developers to reconsider the supervision plan so as to contribute towards professional teaching practices at schools during practicum in Yemen.
“Let us call it a truthful hyperbole!” A Semantic Perspective on Hyperbole in War Poetry on Iraq (2003)
Authors: Halawachy Huda , Alobaidy Nawar
Published: January 2021

As has long been known, though prevalent in everyday discourse across cultures, hyperbole is a neglected figurative language in the linguistic and/or literary sphere. In this talk, we propose a semantic taxonomy of hyperbole in American and British modern war poetry showing how this taxonomy helps readers figure out the poet’s meaning on a deeper level via a variety of hyperboles. The main objectives are to (1) identify the elements of such a trope in the corpora, (2) approach a semantic taxonomy of hyperbolic elements, and (3) come up with the true hidden messages and nature of the trope in accordance with the typology of the semantic field under which the trope is embraced. The corpora consist of two impressive poems – ‘Abu Ghraib’ by Curtis D. Bennett (American), and ‘A Message from Tony Blair to the People of Iraq by David Roberts (British). Findings indicate that both the evaluative and the quantitative dimensions are key characteristics that often coincide and should, therefore, be included in every interpretation of the figurative hyperbolic language in war poetry. A strong preference is also observed for negative effects, auxesis, and absolute savage in the corpora, though the trope sounds positive on the surface.

Local Militia as a Counterterrorism Strategy and Peacebuilding in the erstwhile FATA
Authors: Dr. Rahman Ullah  , Dr. Saeed Ahmed
Published: January 2021

The lashkars have a very long history in the erstwhile Federally Administered Tribal Areas (FATA) of Pakistan. These lashkars were usually constituted in a short span of time to respond quickly to any deteriorating law and order situation. The participants usually acted as volunteers to settle the disputes and soon dispersed. No doubt, this is the concept of the traditional lashkars that provided a basis for the raising of the peace lashkars. This was an announced or informal strategy of the government to counter militants in the tribal belt.  However, some terms like Aman lahkar or Aman lashkar were locally used for the anti-Taliban militias to counter the Taliban in the former FATA. Though the peace lashkars never got any formal name but the government fully supported them by issuing them special permits to keep sophisticated, automatic weapons like AK-47 to combat the militants. The paper investigates the historical perspective behind the formation of the anti-Taliban militias. However, the paper mainly analyse the role of the Anti-Taliban militias in the counterinsurgency and peacebuilding in the erstwhile FATA.

Analysis of Distributional Equity of Public Physical Infrastructure in Pakistan
Authors: Shoukat Ayza , Abdullah Muhammad
Published: January 2021

The significance of public physical infrastructure (PPI) is hard to brush aside. Whereas, misallocation of PPI tends to overshadow the growth as well as creates disruption and unrest among the territories. The theory of public choice proposes that embracing the equity effect in distribution of PPI can improve overall economic growth as well as concord the economic well-being. The current study has empirically tested the equity approach in distribution of PPI among the provinces of Pakistan. We have adopted an innovative approach by analyzing the equity principle. Panel data for provinces of Pakistan has been employed for the period of 1988-2018. The stationarity of the variables has been checked through Levin, Lin & Chu test. As we get mixed order of integration, panel ARDL is used to estimate the results. The study concludes that the distribution of PPI in provinces of Pakistan is based on the equity principle. Whereas the other economic indicator efficiency is traded off against equity. The short run negative and significant ECT term also confirms the existence of long run relationship between variables. These results ensure that despite the heterogenous characteristics of each province, the distribution of PPI is done to equalize the living standards across the country.

Authors: Ullah Faiz , Ashraf Dr. Atif
Published: January 2021

Gender portrayal and the representations of males and females in advertising remains the core interest of researchers from gender studies and communication research. In advertising scholarship, it is often found that there are differences in gender portrayal specifically due to the cultural contexts. In the present study, we explore the gender portrayal in outdoor billboard advertising of two provinces of Pakistan; Punjab and KPK. Theoretically and conceptually, the study takes roots from cultural studies on advertising and social semiotics studies on gender and advertising. We collect data of 360 billboard advertisements from two cities of Punjab and two cities of KPK. We coded 654 units in these 360 billboards according to the conceptual categories of social semiotics. In the present study we found that female models are portrayed more as compare to the male models in outdoor advertising of both provinces; Punjab and KPK. Although, the dominant pattern of gender portrayal in advertisements of KPK is similar to Punjab, however, it is slightly different from Punjab. In KPK, males are also portrayed as submissive. Females are more associated with nurturing roles as compared to Punjab. Hence, it is concluded that in outdoor advertising of Pakistan, females are objectified and they are mostly used for their glamour and beauty. On the contrary, males are portrayed as dominant and in power.

Intensive use of agricultural production technologies has recognized the intensive characteristics of agricultural producers, which allowed to present the need for frequent diagnostics, maintenance and repair.
This transition is due to objective trends in the development of agricultural machinery. The solution to this problem involves the development and creation of effective tools for monitoring and diagnosing the state of the transmission elements of agricultural machinery; assessment of the value of the residual life of individual elements of the system and the study of energy conversion processes in these elements; construction of mathematical models on the basis of which it is possible to predict the occurrence of dangerous damage depending on the operating conditions of the equipment. Diagnostic means must ensure the assessment of the condition of the working surfaces of the interacting transmission elements, control of wear of their surfaces and assessment of the performance of the unit as a whole or the kinematic pair without their disassembly during operation. The time of collection of diagnostic information and allocation of informative signs and parameters of signals should be minimized. Control methods should be as simple as possible, and the means that implement them - compact, with built-in algorithms for information processing and decision-making.
The most informative parameter that carries the maximum information about the state of the unit of a working machine or unit is mechanical oscillations (vibrations) - elastic waves propagating in continuous media.
Measurement of vibroacoustic characteristics on bearing supports of mechanisms allows to recognize such defects and damages as imbalance and skew of shafts; damage to plain and rolling bearings; damage to gears in gears; damage to couplings; damage to electrical machines.
With the systematic use of modern diagnostic methods it is possible to avoid serious damage to the transmission elements and reduce operating costs for maintenance of agricultural machinery due to the fact that the repair is carried out only when the measurement results indicate its need.

There are schemes of equipment for dehydration of damp dispersive waste of food productions (spirit grain, beer pallets, beet pulp, coffee and barley slag) analyzed in this article. These wastes at the majority of food enterprises of Ukraine are poured out onto the ground and that leads to environment pollution. However, in case of dehydration of these wastes to humidity 20 – 25%, they can be used as valuable additions to agricultural forages or as high-energy fuels. Thus, the problems of waste utilization and protection of nature from pollutions are resolved simultaneously. Besides, the enterprise gets a profit from the sales of forage additions or fuel. The known equipment for mechanical dehydration, for example, the screw-presses and the decanter centrifuges, provides the waste final humidity no less 74 – 76%, therefore waste demand of an additional drying after the dehydration at this equipment. That brings to a significant increase of energy expenses. An application of the vibro-blowing dehydration at the installations with the hydraulic pulse drive provides waste final humidity 20 – 25%, but these installations are complex by design, have big dimensions and high cost. A drying in pulverizing or in vacuum dryers is most power-consuming dehydration method (expenses of energy - 740 ÷ 2248 kW h/ ton of dehydrated waste). Equipment for the chemical and biological dehydration is the large multiple-unit complexes with low specific productivity. Therefore, article authors offer a scheme of the installation with the combined unbalanced and hydraulic drive that has a relatively simple design, compact dimensions, high reliability and at the same time, in correspondence with the authors’ estimation, will provide necessary, above indicated humidity. Also equations for determination of the main working parameter – the pressure in the press-form of the proposed installation are presented in the article.

Technological progress is characterized by continuous expansion of automation of all sectors of human activity, the transition from partial automation to integrated, and then from integrated automation to complete, which provides the highest technical and economic efficiency.
The 21st century is called the information age, because the main successes of technological progress are now observed precisely in the introduction of information technology to various means and systems of automation. Automation is not possible without measuring equipment. The development of control and measurement technology for automation systems is largely determined by advances in compatible fields of science and technology - in microelectronics, computing, solid state physics, etc. It is for the developers of automation systems and control of various technological parameters that the most favorable environment of practical activity is now created in the form of a huge nomenclature of miniature and reliable sensors, which are easily combined with secondary equipment and allow to transmit measurement information over long distances in the conditions of intensive industrial interferences.
Temperature measurement and control tools have long been at the forefront of automated control of many technical processes, the complication of which leads to the need for a sharp increase in the number of measurement channels to obtain complete and objective information about the temperature modes of the processes.
In this regard, a computerized temperature control system for crude natural gas air coolers (APOs) is no different than sophisticated industrial automation systems. Given the fact that gas pipelines are an important part of the industrial complex of Ukraine, the development of a modern computerized temperature control system for air coolers for raw natural gas is, without doubt, an urgent scientific and technical task.
