Determination of preservice special education teachersâ€™ views on early childhood intervention
Authors: Baglama Basak , Demirok Mukaddes Sakalli
Published: December 2016

Experiences in early childhood have a great influence on a child's physical and mental development. Early childhood interventions are widely accepted as an effective way to prevent learning difficulties and to promote healthy development for children with special needs. For this reason, it is important for teachers who will work with children with special needs or children who are at risk to have sufficient knowledge about early childhood intervention and be competent in this area. Therefore, the present study aims to determine the views of preservice special education teachers about early childhood intervention. This study used quantitative research method and a questionnaire form was used to collect the data. The results are discussed in detail with reference to relevant literature. Implications and recommendations for further research are also provided in order to improve the quality of education policies, programs and practices related with early childhood intervention and increase awareness and knowledge related with early childhood interventions among teacher candidates.

Improvement Of Competitiveness In Small And Medium-Sized Enterprises
Authors: Park Kyung Jin , Yoo Youngtae
Published: December 2016

While SMEs (small and medium-sized enterprises) contribute much to the economy, their competitiveness compared to that of large enterprises is negligible. Periodic evaluation of the overall competitiveness of SMEs is important to determine the reasons behind their relatively low growth rate. In order to maximize the effects of support for SMEs through government policies, determining the best means of providing support and enhancing competitiveness is necessary. Government funds or other sources of support for SMEs must be supplied according to the circumstances surrounding each enterprise. For instance, if the government invests in tangible assets, SMEs must be the target, because their size guarantees that despite their lower flexibility, competitiveness will improve. If investment is made in research and development, the firm’s long-term capacity for growth must be evaluated rather than its profitability, since there is an immediate increase in costs. There are differences in the effects of investment on flexibility, immaterial capital, and the ability to compete according to the size of the firm and the number of years it has been in business; these factors must be taken into account. Also, in allocating supporting funds to SMEs, the sites at which the funds are to be used must be examined. Active use of funds in areas where SMEs cannot invest in themselves is encouraged, rather than investment in general.
The Effect Of Accruals Quality On The Association Between Voluntary Disclosure And Information Asymmetry In Korea
Authors: Shin Hoyoung , Oh Hyunmin
Published: December 2016

Using data on the firms' voluntary disclosures from the Korea Stock Exchange from 2011 to 2014, we first empirically examine the association between voluntary disclosure and information asymmetry and then investigate the extent to which this association is affected by accruals quality since Korea adopted International Financial Reporting Standards (IFRS) in 2011.   We use Comprix et al. (2011) and Shin and Park (2014)'s measures of information asymmetry. They are daily stock return volatility (VOLA) and trading volume turnover (VOL). We use the Dechow et al.'s (1995) revised Jones model and the Kothari et al.'s (2005) performance matched discretionary accrual model to measure the discretionary accruals. The absolute values of discretionay accruals are used as proxies for accruals quality. Final research samples with voluntary disclosure for this study are 1,226 (firms-years) companies. The research findings generally support our hypotheses. First, the relation between voluntary disclosure and information asymmetry is statistically and significantly positive as we have expected. The Korean companies with high voluntary disclosure would experience higher daily stock return volatility and less trading volume, which implies that companies tend to disclose biased information to the outside, which is consistent with prior studies in Korea. Second, the accruals quality (moderating variable) on the relation between voluntary disclosure and information asymmetry is statistically and significantly negative. Thus, we can conclude that when accruals quality is high, more voluntary disclosure decreases information asymmetry. These findings imply that accruals quality works as a mechanism in reducing the negative effect of voluntary disclosure on information asymmetry after the adoption of IFRS in Korea. The limitation of this study is such that we might not have considered other omitted variables and other proxies for the accruals quality, voluntary disclosure, and information asymmetry.
El Muntu: la diáspora del pensamiento filosófico africano en Changó, el gran putas de Manuel Zapata Olivella
Authors: Sierra Díaz Diana Carolina
Published: December 2016

La problemática del fenómeno diaspórico en América es un elemento notable en Changó, el gran putas. En esta novela el éxodo africano se encuentra estrechamente relacionado con la filosofía Muntu. Esta filosofía agrupa unos saberes africanos compuestos de diversos elementos que resurgen en América transformándose dentro de un contexto de intercambio cultural postcolonial. En Changó, el Muntu nos permite analizar no solo la posibilidad de tejer una alianza africana y mestiza en pos de libertad en América, sino que constituye además una metáfora del mestizaje americano, una oportunidad de ver la Historia de este continente desde un punto de vista literario involucrando asimismo diferentes dimensiones del ser humano. Proponemos una reflexión en torno a la manera como las diferentes categorías filosóficas del Muntu (Kintu, Kuntu, Hantu y Muntu) son abordadas y ad[a/o]ptadas desde una perspectiva filosófico literaria, cuestionando su relevancia dentro de la obra.
Conversación sostenida (... con el coreógrafo y poeta José Luis Tahua)

Authors: Mukan Natalia , Fuchyla Olena
Published: December 2016

In the article, the problem of functional literacy training organisation in the system of adult education in Belgium has been studied. The authors analyse the scientific and pedagogical literature which highlights different aspects of the problem under research; characterise the research methodology which comprises theoretical and applied methods. They present the theoretical and methodological framework (humanistic, pluralistic, andragogy concepts) of functional literacy learning; different approaches (standard, context, social and cultural) to the term “functional literacy” treatment; concretise the definition of “functional literacy”. The scholars study prerequisites (historical, political, social and cultural, social and economic, linguistic) of adults’ functional illiteracy development in the modern Belgian society. The researchers characterise the system of adult education according to the structural and functional approach, especially, its legislative, managerial, organisational, and academic levels. They present the systematised and generalised specificities of learning organisation for adults’ functional literacy development in formal education of Flemish Community (Centres for adult education), German-speaking Community (public schools), in non-formal education of French Community (network of volunteer organisations). The scientists analyse the content (knowledge, skills of basic and professional education, social and personal skills, skills for self-education) and operational (organisational forms and methods; methods for learning motivation) components of functional literacy learning. The authors present the research conclusions and perspectives for further research.
TEMPORAL AND LOCATIVE PREPOSITIONS VERSUS ADVERBS: LEXICAL AND GRAMMATICAL OVERLAPPING (CORPUS-BASED STUDY)
Authors: Kovbasko Yurii
Published: December 2016

The paper focuses on an essential problem of a “part-of-speech” theory, including temporal and locative prepositions and adverbs overlapping in lexical and grammatical perspective. The study is pursued on a corpus-based approach towards prepositions and adverbs overlapping in present-day English (PDE), giving consideration to the complements applied. The latter are divided into two wide groups, namely Noun Phrase and Alternative Complements. To organise the results the comparative-parametric method of linguistic research developed by Sternina was introduced. A comparison has been made between traditional interpretation of complement use and practical corpus-based results in PDE. It has been ascertained that among 94 lexical units treated as one-word prepositions 49 units show overlapping of prepositions and adverbs; however, 39 units bear locative and temporal semes. The results of the PDE corpus-based research show that conventional interpretation of prepositions as lexical units governing Noun Phrase Complements and Adverbs as units correlating with Alternative Complements is deceptive, as it is based on a synchronic syntactic approach, neglecting diachronic syntax and semantics. The hypothesis proposed describes a necessity to reconsider modern PoS division theory, taking into account diachronic approach and analysis of lexical units at the stages of their genesis in Old English and Middle English periods.
PEER AND SELF-ASSESSMENT AT ESP CLASSES: CASE STUDY
Authors: Lavrysh Yuliana
Published: December 2016

In order to develop the skills and competences required in a professional environment, university students have to reflect on their own role in the learning process. The traditional methods of assessment do not assess reflective thinking, critical thinking, self-evaluation and peer evaluation. The following paper outlines and evaluates the implementation of peer and self-assessment techniques in higher education, in ESP course at National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute” as a case study. The rationale of the alternative type assessment systems is examined, and the efficiency of these methods is evaluated and compared by the use of attitudinal questionnaires completed by the participating students and the lecturer’s assessments and feedback. The methodology to investigate the effect of peer and self-assessment as a part of the learning process includes literature observation, case study, developing marking criteria, examples of peer and self- assessment strategies and activities in ESP course. Forty quantitative peer and self-assessment studies were subjected to analysis. The study pointed to differences between self and peer assessments. Peer assessment was found to resemble more closely teacher assessments whereas self-assessment demonstrated difference with teacher’s marks. One of the most essential conditions for objective and relevant performance of the evaluation was found as well-understood assessment criteria. Hypotheses concerning the greater validity of peer and self- assessments were not supported. We have drawn the conclusions that the application of peer and self- assessment methods improves students’ critical thinking skills, involves students into learning and assessment processes, keeps motivation up to study and provides them with a greater ownership of the whole learning and assessment process. Therefore peer and self-assessment techniques could be effectively implemented in the course of ESP at universities.
INNOVATIVE APPROACHES TO TEACHING ENGLISH LANGUAGE TO ARTISTS
Authors: Ghritchenko Iryna , Nesterenko Inna
Published: December 2016

The article highlights the problem of foreign language training of future artists in higher educational establishments. The main feature of English for specific purposes (ESP) is a professionally oriented approach to learning English. It involves the formation of students’ ability to foreign language communication in specific areas and situations. Permanent and variable characteristics of a foreign language for specific purposes are given. The main issues of studying ESP by art students include the specifics of lexical content and special format of oral and written texts related to the profession. With the help of dominant perceptual modality diagnostics by S. Yefremtsev, we have defined that 95% of all respondents refer to the visual type. The common features of visuals were taken into account in creating the system of classes based on the communicative approach and the principle of visual perception of information. The article analyzes the content and feasibility of the ESP textbook specially created for future artists. Main lingo-didactic (general teaching) principles of training of speech activity types are described. They include: specific professional area, complexity and interconnectedness of learning types of speech activity, dominance of one type of speech activity at a certain stage of training, learning objectives, gradual and consistent skills formation, the text as a basis for any kind of speaking, the richness of analytical tools in every form of speaking, facilities, and advanced technology training. The article proves the necessity of using Internet resources in teaching ESP.
The Contributions of Physical Education and Game Activities on Behaviors of Autistic Individuals
Authors: Eskicioglu Y. , Coknaz H. , Celen A. , Coknaz D.
Published: December 2016

People are expected to carry out certain roles and duties throughout their lives in a society. The inability of people to carry out their roles and duties in a society due to various factors is defined as “disability.” Considering that there are 1,559,222 disabled individuals in our country, the rate holds an important place within the general population. Each individual is either disabled, has a disabled relative or a candidate for disability. Thus it is necessary to provide suitable conditions to enable disabled individuals live in concert with the society. This study is conducted in order to determine the level of influence of a 28-hour sport and game activity each week, for 14 weeks, on autistic individuals who have weak socializing and communications skills. This research is conducted on 2 male autistic children of a volunteer family during the fall semester of 2014-2015 academic year; this research also includes preliminary test and proof positive through face to face interview with the family. Descriptive analysis and content analysis are used in data analysis. All of the procedures are carried out by qualitative analysis program NVIVO 10. The names of disabled individuals who attended the research are undisclosed. In the end of this research, the statements released during the interviews show that physical education and game activities have an important influence on the development of disabled individuals. In this respect, the statements given at the end of the research are presented as Emotions and Thoughts of the Mother and Emotions and Behaviors of the Children.

Authors: Hani Aditya
Published: December 2016

The productivity of manglid (Magnolia champaca (L.) Baill. Ex Pierre) as the prominent plant commodity in West Java, can be improved by environmental manipulation such as spacing and fertilization. The objective of this research is to identify the effect of plant spacing and the use of goat urine as the leaves fertilizer on manglid planting until 19 month old. We used Randomized Block with Split Plot Design using three times replication. Main factor to be considered is the plant spacing with three different space :3  x 3 m (J1) ; 2  x 3 m (J2) and 2  x 2 m (J), while the secondary factor is three different doses of goat urine given : control (P1), 240 ml (P2), and 480  ml(P3. The results showed that the best treatment of planting manglid were treatment spacing of 2 x 2 m with goat urine fertilizer application as much as 240 ml per plant that produces high 191,5 cm and 3.83 cm of diameter up to the age of 19 months.
Effects of 5 Aza 2’ Deoxycytidine on Proliferation and Differentiation of Embryonic Chick Caudal Region Chondrocytes in Culture
Authors: Haq Samina Hyder
Published: December 2016

DNA methylation is one of the epigenetic mechanisms which have been implicated in cellular differentiation, ageing and disease development. The effect of hypomethylating drug 5-aza-2´deoxycytidine (5-aza dC) on the biosynthetic profile of caudal region chondrocytes from chick sternum was studied in detail. The chondrocytes in culture were treated with varying doses of 5-aza dC for 48h and maintained subsequently without the treatment and harvested at selected time points for analysis of growth and differentiation status. 15µg/ml of 5-aza dC showed optimum Concentration at which there was a significant increase in DNA synthesis and RNA synthesis as per cell basis. There was also a significant increase in total protein synthesis and collagen synthesis as per cell basis at this concentration. This optimal concentration also showed to up regulate the gene expression of Type X collagen and alkaline phosphatase, which are the marker of hypertrophic chondrocyte expression. These results further support the notion that methylation is the major epigenetic factor controlling the differentiation and maturation of chondrocytes.
Data Driven Analytical Modeling of Power Transformers
Authors: Penttonen Jyrki , Lehtonen Matti
Published: December 2016

In power systems there are complex transformer structures, whose accurate analysis is not possible using the techniques available today. This paper presents a systematic data driven analysis method for coupled inductors of arbitrary complexity. The method first establishes a winding matrix N mapping the windings to the limbs of the transformer. A permeance matrix P is created from the reluctance network of the magnetic core. A generalized inductance matrix L mapping currents in the transformer windings to the induced voltages is generated based on the winding (N) and permeance (P) matrices. The inductance matrix representation of a coupled inductor is then transformed to an admittance matrix, which can be integrated to the nodal analysis of the electrical circuit surrounding the coupled inductor. The method presented is validated by simulations with real transformer structures using electromagnetic transient program (EMTP/ATP).

Improving People’s Lives: The Grand Challenges for Engineering
Authors: Meehan Nathan
Published: December 2016

President's column

The first brief flight at Kitty Hawk in 1903 did not immediately make the Wright brothers famous; however, within 5 years, enthusiasm for the new technology began to spread around the world. Louis Blériot won a prize for flying over the English Channel in a heavier-than-air craft in 1909, and Charles Lindbergh won the USD 25,000 Orteig prize for the first nonstop flight between New York and Paris in 1927. Multiple teams competed and spent hundreds of thousands of dollars pursuing the prize. Technical advances developed by the competitors led to multiple advances in aviation, revolutionizing the way the world works.

Incentivizing Technological Innovation

The concept of an inducement prize (as opposed to a recognition prize such as Nobel Prizes) is well established for the solution of a problem that is important to society. The British, Spanish, and Dutch governments all offered monetary prizes as early as 1567 for breakthroughs in determining the longitude of a ship at sea. Many scientists and engineers worked on this problem, resulting in substantial advances in timekeeping, telescopes, and other technologies. The French government offered a large prize during the Napoleonic wars for a way to safely and cheaply preserve large amounts of food, leading to pasteurization advances.

The Ansari XPRIZE challenged teams to build a spaceship capable of carrying three people to 100 km above the Earth’s surface twice within two weeks. The USD 10-million prize was awarded in 2004 and has sparked other XPRIZES designed to encourage advances in oil spill cleanup, adult literacy, medicine, and various technologies. The concept is to specify an audacious goal that will benefit mankind if a significant breakthrough is made.

SPE R&D Committee Identifies Grand Challenges

The National Academy of Engineering incorporated input from leading technological minds to identify 14 “grand challenges” for engineering for the 21st century. Several of these dealt with energy, including making solar energy more commercial, providing energy from fusion, and carbon sequestration. The SPE Research and Development (R&D) Committee identified five grand challenges for the petroleum industry including:

High-resolution subsurface imaging

Challenges in reusing produced water

In-situ molecular manipulation

Increasing hydrocarbon recovery factors

Carbon capture and sequestration

An additional focus on the environment, including minimizing the footprint of oil and gas activities, and oil spill prevention and response were added, so these are often referred to as the “5+1” challenges.
Metal-Formed Liner Hanger Avoids High-Setting-Pressure Requirements
Authors: Mullins Frank
Published: December 2016

Seminole Services announced the commercialization of its first product, the Powerscrew Liner System, a new expandable-liner hanger that is set with torsional energy from the topdrive (Fig. 1). The Louisiana-based company began development on the tool and associated equipment in the fall of 2012. Rooted in solid mechanics and material science, the company provides engineered wellbore solutions to exploration and production companies actively engaged in drilling oil and gas wells.

In the evolution of liner hangers, mechanically set systems were developed first. While many operators believe mechanical systems are more robust and provide superior sealing integrity when compared with hydraulically set hangers, older mechanical systems typically lack reliability, especially in applications requiring longer liners in deviated wellbores. In large part, this is because of the risks associated with reaming a mechanical hanger to setting depth. Reliability rates were increased with the introduction of hydraulically set hangers, which allowed a greater range of applications. However, the newer setting method suffers from its own limitations, such as flow-area restrictions, compatibility with drilling-fluid additives, and a multitude of potential leak paths.

With the advent of expandable-liner hangers, further increases in setting reliability were achieved along with even greater applications. The increase in reliability stemmed, at least in part, from greater success reaming the liner to setting depth. The higher reliability of expandables is perhaps a consequence of greater flow area at the liner top and the lack of external setting devices. This has led to many new developments in drilling with liners (DWL).

Nevertheless, expandable-liner hangers continue to suffer from potential leak paths associated with high hydraulic pressure sourced at the mud pumps. The hydraulic pressure provides energy to the running tool necessary in setting the liner top. In most expandable systems, pressure pushes the roller/ expansion cones/sleeve through a metal-formed tubular by use of a multitude of pressurized connections and fluid ports. By contrast, the torsionally set system combines the latest in metal-forming technology along with the best features of mechanically set systems. The result is a setting process that does not require high hydraulic pressures and eliminates the risks associated with reaming the liner to setting depth and DWL.

Technology Update

A challenging commodity price environment has forced operators to seek methods for sharply lowering recovery cost per barrel of oil equivalent (BOE) in unconventional plays.

Some reduced costs have resulted from the overcapacity of global services. Other reductions have resulted from declining industry activity, which has increased the availability of personnel and led to a renewed focus on maximizing drilling and completion (D&C) process efficiency.

A portion of the recovery cost reduction has resulted directly from incremental technical innovations and process improvements that were difficult to achieve when operators and service companies were concerned chiefly with D&C execution.

Older processes were designed to maximize early production, whereas a number of newer technologies focus on maximizing net present value (NPV). High NPV is most often achieved by reducing uncertainty and manipulating the cost portion of the NPV equation, especially when the commodity price and/or discount rate is uncontrollable.

D&C portfolios have primarily contained a mix of delineation wells and development wells. Delineation wells have a higher cost per BOE but a higher potential for accelerating reserve recovery. Development wells have a lower cost per BOE but a lower potential for accelerating recovery. This mix of wells is appropriate for periods when margins are high enough to cover the associated D&C costs. However, the loss of such margins in a low-price environment has prompted adjustments to lower the average cost per BOE.

One strategy for lowering that cost is to increase the percentage of refractured wells in a portfolio. Typically, the cost per BOE of refracturing is substantially lower than that of drilling and completing delineation or development wells.

Recently, the development and implementation of effective stimulation diversion techniques and greater focus on candidate screening have narrowed the window of uncertainty in executing refracturing operations in horizontal wells. These improvements have reduced the economic risk of these operations and created further incentive to shift portfolio strategies toward refracturing.

Taking advantage of refracturing opportunities in a portfolio involves four steps.

Screen the best candidate properties, based on reservoir quality and the potential to exceed the original completion quality.

Design the optimal refracture treatment to place new conductive fractures where desired and reconnect existing ones.

Execute the refracture treatment for coverage of all selected lateral areas, using the latest processes, techniques, and materials.

Diagnose the refracture performance and optimize the refracture design for analogous properties, using state-of-the- art diagnostic tools.

This article primarily discusses the candidate selection process.
Innovative Developments in Caspian Republics’ Oil and Gas Production
Authors: Carpenter Chris
Published: December 2016

The past decade has seen the Caspian Sea region come into its own as one of the world’s most important frontiers in oil and gas production. Though it saw some of the first oil-producing wells of the modern era, the region’s importance to the global industry—if not to the Soviet Union, which long constituted most of its shoreline—waned as the Middle East took center stage. But with exploration and production (E&P) efforts expanding, geopolitical realities changing, and technology bounding forward, the Caspian has again moved into the spotlight.

Along with the Russian Federation and the Islamic Republic of Iran, three Central Asian republics—Azerbaijan, Kazakhstan, and Turkmenistan—share the Caspian’s extensive shoreline and, to varying degrees, its enormous potential for oil and gas production. All three republics are in the midst of intensive efforts to underpin their developing economies by increased exploitation of massive reserves.

Boundary and rights disputes among the neighbors over Caspian waters are common, and often greatly complicate investment opportunities. Azerbaijan’s oil reserves are estimated to be approximately 7 billion bbl, with gas reserves of 35 Tcf; Kazakhstan’s oil and gas reserves both rank well within the world’s top 20, at 30 billion bbl and 1.5 Tcm, respectively; and Turkmenistan’s gigantic gas reserves are among the world’s largest at 17.5 Tcm. In their third decade of full independence, all three nations have encountered challenges in contacting, producing, and exporting their impressive resources.

Some of these challenges, such as struggles with creating an efficient infrastructure and a skilled domestic labor force, are endemic to emerging nations, while others are particular to the broad range of climactic and environmental conditions that encircle the world’s largest enclosed inland body of water. As the three young republics search for the best way to solidify economic and geopolitical identities as stable industry producers, a proliferation of companies has established a presence both on- and offshore. Most Caspian oil production currently comes from onshore fields, but offshore production is viewed as the primary target of future development. The goal now is to successfully expand and nurture these economic identities while best serving the world’s energy needs in a period of uncertainty.
EOR-Feasibility Study for a Large Carbonate Field in Kuwait

This paper presents the results of reservoir simulations for the Mauddud reservoir in the Sabiriyah field (SAMA) in Kuwait, which is a high-temperature and high-salinity carbonate reservoir. The subject reservoir has been under pattern waterflood. Many wells experienced water breakthrough with considerable increase in water cut because of high reservoir heterogeneity and adverse mobility ratio. This study provides technical analysis of the viability of enhanced-oil-recovery (EOR) processes; the results indicate the potential for significant improvement in recovery efficiency over continued waterflooding.

Introduction

SAMA is a giant carbonate oil reservoir covering more than 200 km2 in northern Kuwait. Oil production began in January 1958 and continued under primary recovery until 2000. In 1998, a waterflood pilot was conducted successfully. As a result, inverted-nine-spot waterflood patterns were implemented in 2001. As of 2011, the fieldwide water cut reached approximately 30%.

Sector Model

A large sector model was developed to study field-scale fluid-flow behavior in SAMA. The first step in generating a sector model was to identify an area of interest (AOI) suitable for EOR applications. A sector geocellular model was then developed for the selected AOI with available petrophysical and geological data. A sector simulation model was obtained from the upscaling of the sector geo cellular model. The sector simulation model was calibrated with the production, pressure, and other surveillance data from the wells in the sector-model area. The history-matched model was then used to perform gas-EOR-forecast simulations. Details of this process are provided in the complete paper.
