Authors: Chen Chuanmiao , Wang Xiangqi , Hu Hongling 
Published: January 2017

AbstractA high-efficient algorithm to solve Crank-Nicolson scheme for variable coefficient parabolic problems is studied in this paper, which consists of the Function Time-Extrapolation Algorithm (FTEA) and Matrix Time-Extrapolation Algorithm (MTEA). First, FTEA takes a linear combination of previous l level solutions as good initial value of Un(see Time-extrapolation algorithm (TEA) for linear parabolic problems, J. Comput. Math., 32(2) (2014), pp. 183–194), so that Conjugate Gradient (CG)-iteration counts decrease to 1/3~1/4 of direct CG. Second, MTEA uses a linear combination of exact matrix values in level L, L+s, L+2s to predict matrix values in the following s–1 levels, and the coefficients of the linear combination is deduced by the quadric interpolation formula, then fully recalculate the matrix values at time level L+3s, and continue like this iteratively. Therefore, the number of computing the full matrix decreases by a factor 1/s. Last, the MTEA is analyzed in detail and the effectiveness of new method is verified by numerical experiments.

Published: January 2017

Objective: The purpose of this pilot study was to understand nursing students’ perception of the relationship between sleep deprivation and learning, and personal and patient safety when in a clinical or work setting.Methods: Design: The researchers used a cross-sectional correlational design. Setting: The study was conducted in a Mid-western state university school of nursing with an average of 400 undergraduate pre-licensure nursing students. Sample: All 328 undergraduate pre-licensure nursing students were invited to participate in the study. The convenience sample of 179 (response rate of 55%) pre-licensure, nursing students completed the study. Methodology: The Sleep Deprivation of Nursing Students, a 4-point Likert scale questionnaire, consisted of demographic questions and forty-five questions on personal sleep habits, caffeine/stimulant use, and sleep inducing aids, motor vehicle safety, spare time activities, and safety during work and clinical experiences.Results: One hundred and fifty-five (n = 155) students needed seven or more hours of sleep daily to feel rested, but received less than 5 hours/day. All participants reported (n = 179) feeling sleep deprived. Sleep inducing aids were used by (n = 56) participants, and (n = 35) took stimulants to stay awake. Students (n = 166) worked 8 or more hours at a job, and (n = 158) had at some 12 hour school clinical rotations, and (n = 64) reported a combined clinical and work of five to greater than 12 consecutive days. Students (n = 172) believed they provided safe practice at work and (n = 174) and safe practice in a clinical setting. Some students reported being awake 17-19 hours. The majority of students (n = 144) believed 12-hour-clinicals were too long, yet more than half of the students preferred 12-hour work and clinical experiences.Conclusions: Nursing students may lack the knowledge that chronic sleep deprivation may result in personal and patient safety issues when in a clinical or work setting. Students are potentially exposing themselves to acute and chronic health problems as a result of sleep deprivation and the use of substances to remain awake or obtain sleep. Nurse educators and nurse managers must collaborate to reduce the number of consecutive clinical and work shifts, limit overtime hours, and better educate students on the negative impact of sleep deprivation.

De afwikkeling/vereffening van een fideï-commissaire nalatenschap na de vervulling van de voorwaarde
Dit artikel gaat in op de afwikkeling en vereffening van de fideicommissaire (of tweetraps)nalatenschap. Als de bezwaarde komt te overlijden, moet zijn eigen nalatenschap en die van de insteller worden afgewikkeld/vereffend. Voor de vraag wie welke nalatenschap afwikkelt of vereffent en wie in welke nalatenschap een vereffenaar kan laten benoemen, moet scherp onderscheid worden gemaakt tussen de beide nalatenschappen. Voor elke nalatenschap geldt een eigen regime, ook al zijn de nalatenschappen wellicht met elkaar verweven.

Toekomst voor toezicht: open samenleving, open toezicht?
Afgelopen voorjaar hielden twee hoogleraren een intreerede over het thema toezicht. Op 17 maart jl. gaf Judith van Erp aan de Universiteit Utrecht een oratie die de titel meekreeg: Toezicht in een open samenleving. Maatschappelijke controle op multinationale ondernemingen. Kort daarna, op 29 maart, hield Femke de Vries haar oratie aan de Rijksuniversiteit Groningen, getiteld: Leidt transparantie tot meer vertrouwen in de toezichthouder? In dit artikel bespreken wij deze bijdragen in onderlinge samenhang, vanuit de verbindende vraag: is een open samenleving gebaat bij openheid over wat toezicht vermag?
Book Review: The 21st-Century Voter: Who Votes, How They Vote, and Why They Vote
Authors: Deutsch Anne C. 
Published: January 2017

The title of this two volume set suggests that the focus is on voters: their demographics, voting preferences, and motivations. However, the editors state “the aim . . . is to assemble many of the key concepts and issues that drive 21st century politics,” (xiii) a far more sweeping goal and one more difficult to attain. While not stated explicitly here or elsewhere, the entries that are related to voting focus on United States presidential and congressional elections. Taken as a whole, this work is a collection of loosely related entries, many of which don’t state a connection to voters or voting.
Compiling an OPEC Word List: A Corpus-Informed Lexical Analysis
Authors: Saleh Aluthman Ebtisam 
Published: January 2017

The present study is conducted within the borders of lexicographic research, where corpora have increasingly become all-pervasive. The overall goal of this study is to compile an open-source OPEC[1] Word List (OWL) that is available for lexicographic research and vocabulary learning related to English language learning for the purpose of oil marketing and oil industries. To achieve this goal, an OPEC Monthly Reports Corpus (OMRC) comprising of 1,004,542 words was compiled. The OMRC consists of 40 OPEC monthly reports released between 2003 and 2015. Consideration was given to both range and frequency criteria when compiling the OWL which consists of 255 word types. Along with this basic goal, this study aims to investigate the coverage of the most well-recognised word lists, the General Service List of English Words (GSL) (West ,1953) and the Academic Word List (AWL) (Coxhead, 2000) in the OMRC corpus. The 255 word types included in the OWL are not overlapping with either the AWL or the GSL. Results suggest the necessity of making this discipline-specific word list for ESL students of oil marketing industries. The availability of the OWL has significant pedagogical contributions to curriculum design, learning activities and the overall process of vocabulary learning in the context of teaching English for specific purposes (ESP).Keywords: Vocabulary Profiling- Vocabulary Learning- Word List- OPEC- ESPOPEC stands for Organisation of Petroleum Exporting Countries.
Case Markers in Mongolian: A Means for Encoding Null Constituents in Noun Phrase and Relative Clause
Authors: Otgonsuren Tseden 
Published: January 2017

This paper focuses on the capacity of the case markers in the Mongolian language, as a relative element, to generate any finite noun phrase or relative clause based on their syntactic function or relationship. In Mongolian, there are two different approaches to generate noun phrases: parataxis and hypotaxis. According to my early observation, if the noun phrase generated through the parataxis, is the complement of the postpositional phrase, the head word of the relevant noun phrase can be truncated. In other words, since this head noun is governed by case marker in its null form to generate the postpositional phrase, the head noun can be encoded. The second approach generates two different types of noun phrases in their structures: free structured and non-free structured noun phrases. Of them, the free structured noun phrase allows any syntactic transformations in their internal structure based on the senses of the case markers which denote a relation. That is to say, the null constituents in this type of noun phrases can be encoded to generate an extended alternative of the noun phrase and a relative clause.
Patriarchal Regime of the Spectacle: Racial and Gendered Gaze in Jhumpa Lahiri’s Fiction
Authors: Pourya Asl Moussa , Farhana Low bt Abdullah Nurul 
Published: January 2017

This article attempts to evince the political, cultural and affective consequences of Jhumpa Lahiri’s diasporic writings and their particular enunciations of the literary gaze. To do so, it details the manner in which the stories’ exercise of visual operations rigidly corresponds with those of the Panopticon. The essay argues that Lahiri’s narrative produces a kind of panoptic machine that underpins the ‘modes of social regulation and control’ that Foucault has explained as disciplinary technologies. By situating Lahiri’s stories, “A Real Durwan” and “Only Goodness,” within a historical-political context, this essay aims at identifying the way in which panopticism defines her fiction as both a record of and a participant in the social, sexual and political ‘paranoia’ behind the propaganda of America’s self-image as the land of freedom. We maintain that Lahiri’s fiction situates itself in complex relation to the postcolonial concerns of the late twentieth century, suggesting that through their fascination with a visual literalization of the panoptic machine, and by privileging the masculine gaze, the stories legitimate the perpetuation of socially prescribed notion of sexual difference.

Augmenting Tertiary Students' Soft Skills Via Multiple Intelligences Instructional Approach: Literature Courses in Focus
Authors: Eman El Sherief 
Published: January 2017

The second half of the twentieth century is a witness to an unprecedentedly soaring increase in the number of students joining the arena of higher education(UNESCO,2001). Currently, the number of students at Saudi universities and colleges exceeds one million vis-à-vis 7000 in 1970(Royal Embassy of Saudi Arabia, Washington). Such enormous body of learners in higher education is per se diverse enough to embrace distinct learning styles, assorted repertoire of backgrounds, prior knowledge, experiences, and perspectives; at this juncture, they presumably share common aspiration which is hooking a compatible post in the labor market upon graduation, and to subsequently be capable of acting competently in a scrupulously competitive workplace environment. Bunch of potentialities and skills are patently vital for a graduate to reach such a prospect. Such bunch of skills in a conventional undergraduate paradigm of education were given no heed, being rather postponed to the post-graduation phase. The current Paper postulated tremendous merits of deploying the Multiple Intelligences theory as a project-based approach, within literature classes in higher education; a strategy geared towards reigniting students’ engagement, nurturing their critical thinking capabilities, sustaining their individualistic dispositions, molding them as inquiry-seekers, and ending up engendering life-long, autonomous learners, well-armed with the substantial skills for traversing the rigorous competition in future labor market. Keywords: Multiple intelligences, teaching Literature, motivation, autonomous learning, critical thinking.

This paper describes the pilot study in implementing a public speaking module for a primary school level. The module development was structured according to ASSURE Model with the Communicative Language Teaching (CLT) as the basis used in designing the module activities. One group of Year 4 students from an Islamic integrated school was selected and the research method employed was the quasi-experimental research with pre and post-tests as well as interviews with the English teachers on the students’ performance and self-confidence. Students were also interviewed to identify their self confidence level before and after the implementation of the public speaking module. This research project is hoped to increase students’ oral proficiency along with increasing self-confidence in public speaking at a young age, and to propose the implementation of this module as reference in primary education.Keywords: public speaking, primary school, oral proficiency, self-confidence, CLT
Translation of Culture Specific Items: A Case Study of Persian Architecture Terminology
Authors: Bagheridoust Esmaeil , Mahabadi Mahabad Zahra 
Published: January 2017

Architectural texts involve a great deal of CSIs that reflect the culture of a country. Translating these CSIs from Persian into English seems one of the key issues in the translation of architectural texts. This source-oriented descriptive study tried to investigate CSIs of the Persian architecture in order to examine the extent to which the translators/writers have succeeded in rendering CSIs, while translating them from Persian architecture into English or writing on the Persian Architecture in English. In addition, it tried to investigate the most frequently used strategies by writers/translators according to Van Doorslaer’s (2007) model. To serve research purposes, two textbooks on Iranian architecture (i.e., Introducing Persian Architecture by Pope and Abbasid Guest House by Ouliaienia) were sampled. The findings indicated that the translator (Ouliaienia) and the writer (Pope) were successful in finding appropriate equivalents for SL architectural terms. The comparison of Pope’s textbook and Ouliaienia’s translation demonstrated that they had made use of four of the strategies (i.e., Direct Transfer, Word for Word Translation, Interpretation, and Domestication). Accordingly, in pope’s book, Interpretation was the most frequently used strategy, while Direct Transfer was the most frequently utilized one in Ouliaienia. On the other hand, Word for Word Translation was the least frequently used strategy in Pope’s work, whereas Domestication was the least frequently utilized one in Ouliaienia’s work. The findings of the present study may have some significant implications for translation theory and practice.Keywords: Translation, CSIs, Persian Architecture, Terminology
Simulated mussel mortality thresholds as a function of mussel biomass and nutrient loading
Authors: Bril Jeremy S. , Langenfeld Kathryn , Just Craig L. , Spak Scott N. , Newton Teresa J. 
Published: January 2017

A freshwater “mussel mortality threshold” was explored as a function of porewater ammonium (NH4+) concentration, mussel biomass, and total nitrogen (N) utilizing a numerical model calibrated with data from mesocosms with and without mussels. A mortality threshold of 2 mg-N L−1porewater NH4+was selected based on a study that estimated 100% mortality of juvenileLampsilismussels exposed to 1.9 mg-N L−1NH4+in equilibrium with 0.18 mg-N L−1NH3. At the highest simulated mussel biomass (560 g m−2) and the lowest simulated influent water “food” concentration (0.1 mg-N L−1), the porewater NH4+concentration after a 2,160 h timespan without mussels was 0.5 mg-N L−1compared to 2.25 mg-N L−1with mussels. Continuing these simulations while varying mussel biomass and N content yielded a mortality threshold contour that was essentially linear which contradicted the non-linear and non-monotonic relationship suggested by Strayer (2014). Our model suggests that mussels spatially focus nutrients from the overlying water to the sediments as evidenced by elevated porewater NH4+in mesocosms with mussels. However, our previous work and the model utilized here show elevated concentrations of nitrite and nitrate in overlying waters as an indirect consequence of mussel activity. Even when the simulated overlying water food availability was quite low, the mortality threshold was reached at a mussel biomass of about 480 g m−2. At a food concentration of 10 mg-N L−1, the mortality threshold was reached at a biomass of about 250 g m−2. Our model suggests the mortality threshold for juvenileLampsilisspecies could be exceeded at low mussel biomass if exposed for even a short time to the highly elevated total N loadings endemic to the agricultural Midwest.

The quantification of flow stroke volume is important for evaluation of patients with cardiac dysfunction and cardiovascular disease. Three‐dimensional digital color Doppler flow imaging allows the acquisition of flow data in an orientation approximately parallel to flow and analysis of the Doppler flow velocities perpendicular to flow (cross‐sectional flow calculation). This in vitro study assessed the applicability of this method for quantifying cardiac output in a funnel‐shaped tube model similar to mitral inflow or the left ventricular outflow tract.A new digital three‐dimensional color Doppler method was used to acquire Doppler flow information. Raw scan line data with digital velocity assignments were obtained on a conventional Doppler color flow imaging system with a 180 degrees rotating multiplanar transesophageal probe connected to a computer workstation. Nine stroke volumes (20‐60 mL) with flow rates ranging from 1.5 to 5.28 L/min in a funnel‐shaped pulsatile laminar flow model were studied. Three‐dimensional flow rates were compared with standard‐of‐reference measurements of flow obtained from timed collection in a graduated cylinder and with an ultrasonic flow meter.Within the funnel tube, the flow volumes that were calculated from the first, second, and third depths and the average of all 3 depths correlated well with the actual flow rate (r = 0.97‐0.99). Results from the middle and second levels and from the average of all 3 depths provided the closest fit to the actual flow rates (r = 0.99; y = 0.96x + 0.14; and r = 0.98; y = 1.14x ‐ 0.43, respectively).Although a work in progress, this digital three‐dimensional color Doppler flow measurement method is feasible, accurate, and simple, and it may offer in vivo evaluation of blood volume flow given a favorable orientation between the valve orifice and the scanning device.

Published: January 2017

ObjectivesThe purpose of this study was to test the hypothesis that quantitative ultrasound properties of the calcaneus in Southeast Asian children treated for thalassemia have different characteristics than those of their healthy counterparts and thereby can be used for assessing the risk of osteoporosis.MethodsBroadband ultrasound attenuation and the speed of sound were measured from groups of thalassemic and healthy children and compared with bone mineral density (BMD) estimated from dual‐energy X‐ray absorptiometry to determine intergroup and intragroup dependencies of the measurements and variations with differences in sex and anthropometric characteristics.ResultsBroadband ultrasound attenuation and speed of sound measurements were found to be independent of sex but dependent on age in the thalassemic children. Consistently, broadband ultrasound attenuation had lower values and the speed of sound had higher values compared with those of the healthy children in each age group. Broadband ultrasound attenuation correlated well with the speed of sound and also with age, weight, and height, but the speed of sound did not show an association with these parameters. Broadband ultrasound attenuation correlated moderately with BMD in the lumbar spine and whole body, but the corresponding association was much weaker for the speed of sound. In the thalassemic children, both broadband ultrasound attenuation and BMD increased with age as they grew older but not fast enough compared with the healthy children, and the risk of osteoporosis was greater at older ages.ConclusionsCalcaneal quantitative ultrasound may be used as a diagnostic screening tool for assessing the bone status in thalassemic Southeast Asian children and for deciding whether further dual‐energy X‐ray absorptiometry is needed, particularly in those who are at a greater risk for osteoporosis as identified by low body weight and height.
