Teaching Trans*: Strategies and Tensions of Teaching Gender in Student Affairs Preparation Programs
Authors: S Jaekel Kathryn , Nicolazzo Z
Published: December 2017

Aim/Purpose: The purpose of this article is to outline a pedagogical framework we as trans* educators utilize to center trans* identities and epistemologies in classrooms alongside graduate students.

Background: Little has been written about the experiences of trans* educators in classroom spaces, in particular how gender mediates pedagogical approaches.

Methodology : This article is conceptual in nature, and as such, does not draw on any particular methodology. Instead, we draw from our ongoing experiences as trans* educators in the classroom.

Contribution: Due to the lack of theorizing or empirical work about trans* educators in classroom spaces, this article serves as an entry point into thinking what we as authors describe as ‘teaching trans*.”

Findings: This article is broken into three theoretical components: teaching as trans*, teaching about trans*, and teaching with trans* epistemologies.

Recommendations for Practitioners: Through this article, we as authors encourage practitioners to be aware of how gender is always already present in all spaces, including in classrooms. Thus, it becomes incumbent upon practitioners to use expansive notions of gender through pedagogical strategies, materials, and praxis.

Recommendation for Researchers: This article promotes a deeper understanding of how one’s gender identity, expression, and/or embodiment mediates and can enhance classroom teaching. While this article starts to address an under-theorized and under-researched area of study, more should be done to address how gender influences pedagogy.

Impact on Society: Due to the omnipresence of gender binary thinking, this article has implications not just for classroom spaces, but for student affairs graduate preparation programs, as well as society writ large.

Future Research: This article opens the door for further research into student resistance to trans* and gender nonconforming educators’ pedagogy.
Undergraduate Haredi Students Studying Computer Science: Is Their Prior Education Merely a Barrier?
Authors: Genut Sarah , Ben-David Kolikant Yifat
Published: December 2017

Aim/Purpose: Our research focuses on a unique group a students, who study CS: ultra-orthodox Jewish men. Their previous education is based mostly on studying Talmud and hence they lacked a conventional high-school education. Our research goal was to examine whether their prior education is merely a barrier to their CS studies or whether it can be recruited to leverage academic learning.

Background: This work is in line with the growing interest in extending the diversity of students studying computer science (CS).

Methodology: We employed a mixed-methods approach. We compared the scores in CS courses of two groups of students who started their studies in the same college in 2015: 58 ultraorthodox men and 139 men with a conventional background of Israeli K-12 schooling. We also traced the solution processes of ultraorthodox men in tasks involving Logic, in which their group scored significantly better than the other group.

Contribution: The main contribution of this work lies in challenging the idea that the knowledge of unique cultures is merely a barrier and in illustrating the importance of further mapping such knowledge.

Findings: The ultraorthodox group’s grades in the courses never fell below the grades of the other group for the duration of the five semesters. Due to their intensive Talmud studies (which embeds Logic), we hypothesized they would have leverage in subjects relating to Logic; however this hypothesis was refuted. Nevertheless, we found that the ultraorthodox students tended to recruit conceptual knowledge rather than merely recalling a procedure to solve the task, as novices often do.

Recommendations for Practitioners: We concluded that these students’ unique knowledge should not be viewed merely as a barrier. Rather, it can and should be considered in terms of what and how it can anchor and leverage learning; this could facilitate the education of this unique population.

Impact on Society: This conclusion has an important implication, given the growing interest in diversifying higher education and CS in particular, to include representatives of groups in society that come from different, unique cultures.

Future Research: Students’ unique previous knowledge can and should be mapped, not only to foresee weaknesses that are an outcome of “fragile knowledge” , but also in terms of possible strengths, knowledge, values, and practices that can be used to anchor and expand the new knowledge.
Discovering Higher Education Institutions before Solerno
Authors: R Chambers Crystal
Published: December 2017

Aim/Purpose: The purpose of this manuscript is to bring communities of learners before Solerno, Bologna, and Paris from the margin to the center of history of higher education discourse.

Background: Most history of higher education coursework in the global west begins with institutions of higher learning in western Europe – Solerno, Bologna, and Paris. However, this tradition discounts the histories of higher education particularly of institutions in the global east, which predate European models

Methodology: The author brings these communities of learners from the margins to the center of higher education histories by way of historical overview.

Contribution: In so doing, the author informs scholar instructors of ancient higher education from a more globalized perspective.

Findings: The major finding of this work is that there is a history of higher education prior to the rise of institutions in the global west.

Recommendations for Practitioners: From this work, history of higher education coursework in the global west should be adjusted to include acknowledgement as well as greater exploration of ancient higher education institutions as part of our collective global under-standing of the history of higher education.

Future Research: This work more broadly identifies for open exploration of ancient higher education institutions.
The Voice of Teachers in a Paperless Classroom
Authors: Shonfeld Miri , Meishar Tal Hagit
Published: December 2017

Aim/Purpose: This study took place in a school with a “paperless classroom” policy. In this school, handwriting and reading on paper were restricted. The purpose of this study was to gain insights from the teachers teaching in a paperless classroom and to learn about the benefits and challenges of teaching and learning in such an environment.

Background: In recent years, many schools are moving towards a “paperless classroom” policy, in which teachers and students use computers (or other devices such as tablet PCs) as an alternative to notebooks and textbooks to exchange information and assignments electronically both in and out of class. This study took place in a school with a “paperless classroom” policy. In this school, handwriting and reading on paper were uncommon.

Methodology: This qualitative study involved semi-structured interviews with 12 teachers teaching in a paperless school. The research questions dealt with the instruc-tional model developed, the various ways in which the teachers incorporated the technology in their classrooms, and the challenges and difficulties they encountered.

Contribution: This study provides important advice to the way teachers have to work in paperless classrooms.

Findings: It pointed out the contribution to students in three ways: preparing students for the future; efficiency of learning; empowerment of students. The teachers presented a variety of innovative methods of using the laptops in class and described a very similar structure of the lesson. The teachers described the difficulties involved in conducting a paperless classroom instruction and emphasized that despite the efficiency of the computer and its ability to support the teaching process, they used technology critically. The findings also indicate that some teachers were concerned that the transition from the regular classroom to a paperless one may negatively impact students’ reading and writing skills.

Recommendations for Practitioners: Teaching in a paperless school is challenging. On the one hand, going paperless contributes to active and adaptive learning, efficiency, and the acquisition of 21st-century skills or, as they described their main goal, to prepare students for the future. On the other hand, computers in class cause problems such as distraction and disciplinary issues, information overload, and disorganized information as well as technological concerns.

Impact on Society: Teachers in the paperless school develop a solid rationale relying on ideas for teaching and learning in a paperless environment, and use varied technologies and develop innovative pedagogies. They are aware of the challenges of this environment and concerned about the disadvantages of using the technology. Thus they develop a realistic and critical view of the paperless classroom.

Future Research: Future studies investigating the teachers’ voice as well as the pupils’ aspect could help guide schools in preparing teachers for the paperless classroom.

Does Financial Crisis Affect the Cost of Equity Estimation? Evidence from the Tunisian Stock Exchange
Authors: Mondher Kouki , Elkhaldi Abderrazek , Bouani Wided
Published: December 2017

The aim of this paper is to study the impact of the recent financial crisis on equity cost estimation. We use a data of a 22 firms listed in the Tunisian stock market during the period from July 2006 to June 2011. The choice of this period is motivated by the occurrence of the financial crisis of October 2008, which divides the period into two equal sub-periods. In the first stage, we make abstraction to the crisis impact and we run the three specifications of the cost of equity: the CAPM, the Fama -French three factor model and The Carhart four-factor model. Empirical results confirm the explanatory power of the three specifications in the context of the Tunisian market. We also confirm the existence of a size effect, a book to market effect and a momentum effect. In the second stage, we show that the presence of financial crisis does not affect the cost of equity. However, we note a decrease in the coefficients of the explanatory variable after introducing the dummy crisis variable.

Authors: Sinah Satrugan
Published: December 2017

This study is based on data obtained from the new standardised reporting format introduced by International Monetary Fund. The empirical estimation of relationship between money supply and inflation leads to development of a model, which can be used by policy makers while formulating monetary policy. This model is based on new standardised reporting format, which has a broader approach in terms of capturing monetary aggregates in a country. Thus, as opposed to findings of many earlier studies, which used non-standardised data, this paper shows that an increase in money supply leads to an increase in consumer price index. ly. Finally, the study found that the RGDP of trade partner and bilateral real exchange rate are not statistically significant. empirical evidence linking bank customers’ participation in financial ads to their attitude.

Published: December 2017

It has been established that conventional root canal irrigants cause detrimental effect on the physico-chemical properties of root dentin. This study aims to determine the effect of a novel root irrigant, ginger or Zingiber officinale Roscoe essential oil on root dentin microhardness. Eighty root halves of extracted human teeth were used and prepared by embedding them individually in autopolymerizing acrylic resin. These samples were then divided into four groups (n = 20 each), i.e., i) 0.5% Z. officinale Roscoe oil, ii) 2.5% sodium hypochlorite (NaOCl, positive control), iii) 17% ethylenediaminetetraacetic acid (EDTA, positive control) and iv) normal saline (negative control). Dentin microhardness was measured using Vickers Microhardness Tester with a 50 g load and a 10-second dwell time, before and after immersion in respective solutions for 5 minutes. Measurements were taken in Vickers hardness number (VHN). All samples showed reduction in the microhardness reading; with Z. officinale Roscoe: 34.24 to 25.89, NaOCl: 31.47 to 26.34, EDTA: 33.08 to 26.04 and saline: 29.82 to 27.61 VHN. Although there was significant reduction within the Z. officinale Roscoe group (p < 0.001), the change was indifferent when compared among groups (post hoc Tukey’s HSD test p > 0.05). Within the limitations of this study, Zingiber officinale Roscoe essential oil does alter dentin microhardness but to a similar extent as NaOCl and EDTA.

Authors: Jaafar Farah Hanan Fathihah , Osman Khairul , Kumar Jaya , Ibrahim Siti Fatimah
Published: December 2017

There is no solid conclusion on the conventional sperm parameters in association with alcohol consumption, evaluation of sperm DNA integrity thus become a more reliable parameter. Hereby, this literature search was performed to summarize alcohol consumption on the sperm DNA integrity. A computerized database search was done through MEDLINE via Ovid (since 1946 until August 2017) and Cochrane was used. The following set of keywords: ‘alcohol consumption OR alcohol intake OR alcohol diet OR drinking alcohol OR ethanol diet’ AND ‘sperm DNA OR sperm chromatin OR sperm genome OR sperm histone OR sperm protamine’ were utilised. 24 articles were retrieved where only five studies conform to the inclusion criteria All studies demonstrated a negative effect of alcohol consumption on sperm DNA integrity, regardless of various range of alcohol doses and duration of alcohol consumption. Out of five studies reviewed, four studies were using a different approach to measure the sperm DNA damage. Hereby, this review identified a need to use a single approach of DNA damage test by having various method of alcohol administration and/or vice versa so that the extension of sperm DNA damage to alcohol consumption will have a better conclusion. On the same note, a few studies have reported the reversibility on conventional semen parameters, none has been done on the sperm DNA damage upon alcohol withdrawal. Therefore, the role of alcohol withdrawal on the reversibility of sperm DNA damage needs to be as well investigated further.

Published: December 2017

Dried fruits contained higher amount of energy and nutrient density compared to the fresh ones. This study was conducted to determine and compare the content of nutrients and polyphenols in dried dates, raisin, apricot and fig. Dried fruit samples were bought from three different stores in Selangor and analyzed in triplicates. AOAC (1997) standard methods were used for proximate analyses. The total sugar and polyphenol contents were determined using Dubois and Folin-Ciocalteu methods, respectively. Highest moisture content was found in dried apricots (35.26%) while the lowest one was in Mariami dates (21.68%). Dried apricots also contained highest total ash content (4.54%) while Safawi dates have the lowest one (2.45%). Dried figs contained the highest crude protein (3.93%) and fat contents (4.02%) while Safawi dates have lowest protein (2.57%) and fat (0.09%) contents. Total carbohydrates were highest in Safawi dates (72.81%) and lowest in dried apricots (56.09%). Highest total sugar content found in Mariami dates (48.61%) and lowest in dried apricots (10.35%). Total phenolic content in golden raisin contained significantly (p < 0.001) highest polyphenol content (562.15 mg GAE/100 g) than others while dried figs have the lowest one (151.04 mg GAE/100 g). Dried fruits analyzed in this study contained high nutrients and polyphenol contents which are suitable to be consumed as an alternative for snack, with a caution on the portion size due to the high sugar content.

Authors: Ghazali Ahmad Rohi , Khairuddin Farah Mardhiah , Nagapan Tava Shelan , Basri Dayang Fredalina
Published: December 2017

Canarium odontophyllum or locally known as Dabai in Sarawak is a fruit largely consumed by the locals. Based on previous studies, the plant possessed various biological activities, such as antimicrobial, antioxidant, antifungal and anticancer. Our aim was to investigate the mutagenicity and antimutagenicity of C. odontophyllum acetone leaves extracts by using the Ames test (Salmonella reverse mutagenicity assay).The Ames test also involved the pre-incubation method against Salmonella typhimurium TA98 and TA100 bacterial strains in the absence and presence of metabolic activator S9 system. C. odontophyllum crude acetone extracts were diluted with 10% DMSO to obtain three different concentrations of 3.125, 12.5 and 50 mg/ml. To determine the mutagenicity effects of the extracts, each concentration of the extract was evaluated based on the two-fold value of the number of revertant’s colony in negative control plate as the cut-of point. No mutagenic activity was observed for the frameshift mutation (TA98) and base-pair substitution mutation (TA100) in all concentrations of C. odontophyllum in the presence and absence of metabolic activator S9 system. Antimutagenicity test was carried out to determine the potential of C. odontophyllum extracts to inhibit the mutation induced by specific mutagens. The highest antimutagenic activity was seen in the presence of metabolic activator S9 system with inhibition percentage greater than 50% in both bacteria strains TA98 (62.38%) and TA100 (58.24%). In conclusion, C. odontophyllum acetone leaves extract was not mutagenic and had significant inhibitory effects on mutagenicity in both bacterial strains with and without the metabolic activator S9 system. Our results could contribute to the safe use of C. odontophyllum. In addition, based on the significant antimutagenic activity demonstrated by the C. odontophyllum acetone leaves extracts, the extract could also be developed as a chemopreventive agent.

Authors: Zulfakar Siti Shahara , Baharudin Norfarisya , Bakar Nur Faizah Abu
Published: December 2017

Beef is one of the essential sources of protein in human diet. But retail beef are easily contaminated with pathogenic bacteria and can cause foodborne disease. To determine the bacterial contamination, 45 samples of retail beef including imported beef (n = 24) and local beef (n = 21) were collected from selected wet markets at every district in Selangor. Samples were analyzed for total viable counts (TVC), Escherichia coli, Enterobacteriaceae and the incidence of pathogenic bacteria which are Salmonella spp. and E. coli O157:H7. Overall results showed that all beef samples (n = 45) were positive for TVC and Enterobacteriaceae at an average reading of (mean ± SD) 7.05±0.78 log CFU/g and 5.05±0.87 log CFU/g, respectively. Only 53.3% of the total samples were contaminated with E. coli (4.22±0.60 log CFU/g) whereas only 24.4% of total samples were found to be positive with Salmonella spp. All bacterial count readings fall under the marginal category based on the international standards. There were no significant differences (p > 0.05) in microbial counts between the local and imported beef samples for all parameters. Among the E. coli isolates detected from the beef samples, 3 isolates were identified as E. coli O157:H7. In conclusion, meat safety level for the retail beef sold at wet markets in Selangor and Kuala Lumpur is low and requires more attention from the authorities to ensure its microbiological safety for consumers.
Extension of Rotifer (Brachionus Plicatilis) Inclusions in the Larval Diets of Mud Crab, Scylla Paramamosain (Estampodor, 1949): Effects on Survival, Growth, Metamorphosis and Development Time
Authors: Quy Ong Moc , Fotedar Ravi , Thy Ho Thi Truong
Published: December 2017

The study evaluated the effects of extended dietary inclusions of rotifers (Brachionus plicatilis) on the survival, metamorphosis rate, growth and development time in the larvae of mud crabs (Scylla paramamosain). The five most commonly published feeding regimes of mud crab (S. paramamosain) larvae were selected and tested by including rotifers onto them. Mud crab larvae in the first feeding regime were fed exclusively with Artemia nauplii (control or regime A), while those in feeding regimes 2, 3, 4 and 5 were fed rotifers starting from zoea 1 (Z1) to various development stages of mud crab larvae whereas feeding with Artemia nauplii was commenced from the Z2 stage until the end of the trial (megalopa stage). The results of the larval feeding trial for 24 days of culture showed the progressive decrease in survival of the larvae in all feeding regimes. Extended inclusion of rotifer feeding until Z5 stage resulted in significantly higher survival than in the control from 18 day after hatching onwards. Larval survival was negatively correlated (R2 from 0.78 to 0.90) with the rearing time; however, different feeding regimes had no significant effect on this correlation. Extending inclusion of rotifer feeding until the Z3, Z4 and Z5 stages resulted in higher percentages of megalopa metamorphosis than in regime control, but did not significantly impact development time, carapace width, body length and wet weight of megalopa.

This paper contains reservoir simulation study of carbon storage at Gundih field in Central Java Island, Indonesia. Two different cases of injection simulation were performed and analyzed in this paper. The cases represent the conditions when the smallest and largest volumes of CO2areinjected into the subsurface to see the changes of reservoir that happen after the injection processes. The simulation result shows that when a larger amount of CO2 is injected into the targeted reservoir, it will migrate to the peak of anticline structure located in the southeast of CO2 injection well. The displacement of CO2 in the simulation progress shows that it will not reach the fault location. The geological model for synthetic seismogram calculation is then built based on the simulation reservoir result. The furthest displacement of CO2 is calculated on each case and described as the saturated CO2 layers. Forward modeling is performed to create synthetic seismic gather which will be processed to construct seismic section. The difference between the initial seismic section before the injection process and seismic section including saturated CO2 layer after the injection process will be evaluated by the potential of injected CO2 monitoring using time-lapse seismic survey in the Gundih field.

The effect of particle size on the biosorption process, were investigate and the smallest fraction, was immobilized in Na-alginate. Immobilization had a positive effect on the biosorption process, but due to the inhomogeneity of the granules, bentonite was added as a binding agent. The result was increase of Cu(II) and Zn(II) removal up to 35% and Pb(II) up to 60. The composed granules were used for real effluent treatment. Obtained results indicated that this kind of composite biosorbent can be used in treatment of effluents contaminated with heavy metals pollution.
Context and Linguistic Skills Factors Affecting the Pronunciation of Arabic Proper Names in Speakers of Bahdini Kurdish
Authors: Mohammed Shareef Dilgash
Published: December 2017

The purpose of this research is to explore the pronunciation of Arabic proper names by Bahdini Kurds living in Duhok and the districts around. Thirty-two respondents were selected to say fifty Arabic proper names commonly used by Kurdish today’s society. The variables identified are linguistic skills in Kurdish and Arabic, and the extent of the formality of the context. The study concluded that being a fluent speaker of Arabic gives a Bahdini Kurdish speaker the ability to pronounce the Arabic proper names in a native-like accent. Yet, those speakers have revealed a tendency towards the use of a Kurdish pronunciation of such names when the context was informal. Dissimilarly, the Kurdish pronunciation was regularly used by speakers skilled or unskilled in Kurdish language and linguistics in both formal and informal situations.
Staging Romanticism and Dissidence in Howard Brenton’s Bloody Poetry
Authors: Farhadi Ramin , Mozaheb Mohammad Amin
Published: December 2017

Staging history is an approach of historicism that is widely practiced by the post-1968 British playwrights. Historical playwriting not only helps to identify and unmask repressive power institutions, but also to question the conventional trends in writing history in general. One of these playwrights is Howard Brenton. By staging the history of romanticism in the early nineteenth century and the self-imposed exile of Romantic figures in his play Bloody Poetry (1984) Brenton attempts to achieve multiple purposes. By using literary analysis and historical reading, the researchers identify the causes of Shelley-Byron circle’s self-exile and the way in which a dissident discourse is formed as an opposition to the mechanism of disciplinary power and one of its powerful discourses which is journalism.  In addition to this, they explore Brenton’s main politics of representation of the role and function of poet-intellectual in public and how literature as a dissident discourse may function under the administration of Margaret Thatcher in the UK in the 1980s.

This article focuses on the representations of metafiction in Jaishree Misra’s Ancient Promises(2000), Tanushree Podder’s Escape from Harem (2013), and Ashwin Sanghi’s The Krishna Key(2012). More specifically, the article will tackle metafiction in these works from a narrative point of view. The study will generally deal with metafiction as self-reflexive genre dealing with narrative devices, including the work’s comments on itself as a work of fiction. In this respect, the study is going to approach the narrative elements of the selected works to examine the effect of metafiction in the context of the selected works and how they provide the reader with their complex narrative fabric. Therefore, three main metafictional devices are going to be utilized in the study i.e., the self-reflective devices, the mimetic devices, and the narrative devices. These devices will be elaborated in the light of Patricia Waugh’s metafictional arguments. Consequently, a narrative conceptual framework will be followed to analyze the selected works’ plots.
The Construction of Authentic Muslim Identity among Nationally Diverse Women: The Case of an Arab Woman
Authors: Gokgoz-Kurt Burcu
Published: December 2017

This paper examines religious and ethnic identity construction among nationally diverse Muslim women, and shows how Muslim women may reflect asymmetrical power relations regarding their religiousness. While Muslims are usually treated as one homogenous community by those who are not very familiar with the Muslim communities, within the Islamic world, in fact, some Muslim-majority countries may be more strongly associated with Islam than others. Drawing on data gathered through spontaneous conversations, and informal, unstructured interviews during a gathering of four Muslim women, the present study reveals how one Muslim woman belonging to the Arab world authenticates herself in the presence of non-Arab Muslims through her discourse. Several factors such as economic wealth, heritage, politics, and language seem to help her claim “genuine” membership of Islam.

Authors: Kakaew Jiraporn , Damnet Anamai
Published: December 2017

This classroom based research of a learning strategies model was designed to investigate its application in a mixed-ability classroom. The study built on Oxford’s language learning strategies model (1990, 2001) and fulfilled it with rhetorical strategies to accommodate challenges encountered in the paradigm of English as an international language (EIL). The main purpose aimed to explore Thai students’ self-efficacy beliefs (SE) in reading different texts regarding both Western and Asian styles after receiving a strategies-based training. In this research, thirty-three first-year undergraduate students majoring in English Education were purposively selected as participants for the training. The data from pre and post questionnaires focusing on students’ self-efficacy beliefs was analyzed using descriptive statistic and thematic analysis. The results revealed that students believed to have higher efficacy in EIL textual reading after learning strategies-based training. The presentation will also include discussion and suggestion in implementing rhetorical-language learning strategies in the classroom.

Authors: Sinaga Megawati
Published: December 2017

The Objectives of this paper as an experimental research was to investigate the effect of Roundtable and Clustering teaching techniques and students’ personal traits on students’ achievement in descriptive writing. The students in grade ix of SMP Negeri 2 Pancurbatu 2016/2017 school academic year were chose as the population of this research.. The research design was experimental research by using factorial design 2x2. The students were divided into two experimental groups. The experimental group was treated by using Roundtable teaching technique and control group was treated by using Clustering teaching technique. The students are classified into the introvert and extrovert personal traits by conducting the questionnaire and the students’ achievement in descriptive writing was measured by using writing test, namely ‘Analytic Scoring’ by Weigle. The data were analyzed by applying two-way analysis of variance (ANOVA) at the level of significance α = 0.05. The result reveals that (1) students’ achievement in descriptive writing taught by using  Roundtable teaching technique was higher than that taught by Clustering teaching technique, with Fobs = 4.59>Ftab=3.97, (2) students’ achievement in descriptive writing with introvert  personal trait was higher than that with extrovert personal traits with Fobs=4.90 Ftable=3.97, (3) there is interaction between teaching techniques and personal traits on students’ achievement in descriptive writing with Fobs =6,58 Ftable=3.97. After computing the Tuckey-Test, the result showed that introvert students got higher achievement if they were taught by using Roundtable teaching technique while extrovert students got higher achievement if they were taught by using Clustering teaching technique.
Enhancing Thai Engineering Students’ Complaints and Apologies through Pragmatic Consciousness-Raising Approach (PCR)

Successful communication requires “Pragmatic Competence” or abilities to use appropriate language in transferring one’s needs while maintaining a positive relationship with the interactant (Thomas, 1995; Leech, 1983). This study was an attempt to investigate the pragmatic competence of Thai Engineering students when making complaints and apologies through twelve sessions of a pragmatic consciousness-raising approach (PCR). Perceptions toward the innovative teaching activities were also examined. Both qualitative and quantitative methods were used to collect data from forty-five engineering students (n=45) at a university in Thailand. Pre-test and posttest written discourse completion tests (WDCTs) were administered and a semi-structured interview was conducted. Three native speaker raters scored the performances through WDCTs using assessment criteria from Hudson (2001) and Duan (2008). For data analysis, paired-samples t-test was employed to compare the mean scores of students, while the researcher employed a Grounded Theory’s color coding technique (Strauss & Corbin, 1998) to generate the findings on students’ perceptions about the innovative methods implemented. The results revealed significant development of students’ pragmalinguistic and sociopragmatic abilities in both complaints and apologies. Furthermore, participants perceived the PCR class to be beneficial in four areas: having more awareness of the impacts of social factors in language use, realizing the favor of indirect strategies, more understanding of nonverbal communication, and provision of motivating class atmosphere. However, some participants concerned about three aspects: inadequate confidence to use expressions learned in class in real communication, insufficient endeavor to develop grammar knowledge, and the test abilities of the roleplay test. The results confirm the teachability of pragmatic and the benefits of PCR in EFL contexts; whereas, students’ concern about learning through the approach might be helpful for further teaching practices.

Published: December 2017

An iodine‐mediated oxidative ring contraction of cyclobutanols has been developed. The reaction allows the synthesis of a wide range of aryl cyclopropyl ketones under mild and eco‐friendly conditions. A variety of functional groups including aromatic or alkyl halides, ethers, esters, ketones, alkenes, and even aldehydes are nicely tolerated in the reaction. This is in contrast with traditional synthetic approaches for which poor functional group tolerance is often a problem. The practicality of the method is also highlighted by the tunability of iodine oxidation system. Specifically, combining the iodine(III) reagent with an appropriate base allows the reaction to accommodate a range of challenging electron‐rich arene substrates. The facile scalability of this reaction is also exhibited herein.

The electrochemical performance of the aluminum‐sulfur (Al‐S) battery has very poor reversibility and a low charge/discharge current density owing to slow kinetic processes determined by an inevitable dissociation reaction from Al2Cl7− to free Al3+. Al2Cl6Br− was used instead of Al2Cl7− as the dissociation reaction reagent. A 15‐fold faster reaction rate of Al2Cl6Br− dissociation than that of Al2Cl7− was confirmed by density function theory calculations and the Arrhenius equation. This accelerated dissociation reaction was experimentally verified by the increase of exchange current density during Al electro‐deposition. Using Al2Cl6Br− instead of Al2Cl7−, a kinetically accelerated Al‐S battery has a sulfur utilization of more than 80 %, with at least four times the sulfur content and five times the current density than that of previous work.

Spontaneously solar‐driven water splitting to produce H2 and O2, that is, the conversion of solar energy to chemical energy is a dream of mankind. However, it is difficult to make overall water splitting feasible without using any sacrificial agents and external bias. Drawing inspiration from nature, a new artificial Z‐scheme photocatalytic system has been designed herein based on the two‐dimensional (2D) heterostructure of black phosphorus (BP)/bismuth vanadate (BiVO4). An effective charge separation makes possible the reduction and oxidation of water on BP and BiVO4, respectively. The optimum H2 and O2 production rates on BP/BiVO4 were approximately 160 and 102 μmol g−1 h−1 under irradiation of light with a wavelength longer than 420 nm, without using any sacrificial agents or external bias.

Authors: Cheng Yu , Liu Xing , Dong Zhi‐Bing
Published: December 2017

The Chan–Lam coupling reaction starting from phenyldithiocarbamates and phenylboronic acids is reported. To avoid using the volatile, hazardous, and foul‐smelling thiols, which are sometimes expensive and not sufficiently available, phenyldithiocarbamates can be employed. They are demonstrated to be good sulfuration reagents in the Chan–Lam coupling to prepare biaryl sulfides. By using this protocol, dithiocarbamate substrates with a wide range of functional groups including electron‐rich and electron‐deficient ones are explored to obtain the desired substituted biaryl sulfides smoothly. This method is ligand‐free, has a broad substrate scope, enables good yields, and is easy to perform. It provides a facile and convenient preparation of biaryl sulfides.
