Collaborative foreign language learning practices and design principles for supporting effective collaboration in a blended learning environment

ABSTRACT This paper describes a research study that investigated foreign language students’ collaborative practice in a blended, authentic learning environment. A group of intermediate and advanced level students of Italian at an Australian university interacted and collaborated with each other and with a group of native speaker mentors through a web-based learning management system and in face-to-face mode. As part of the project, students were required to complete two authentic tasks designed according to an authentic learning framework. In order to complete these tasks, students assigned themselves into small collaborative groups and negotiated their roles and responsibilities with little or no intervention from the class teacher apart from the requirement that communication took place in the target language. This paper describes the different phases of the collaborative process and the strategies employed by learners to overcome some of the challenges and problems encountered. The paper concludes with a series of recommendations for language educators seeking to support student collaboration and foreign language development in a blended language learning environment.
Urban nitrogen budgets: flows and stock changes of potentially polluting nitrogen compounds in cities and their surroundings – a review

ABSTRACT Concepts of material flow and mass consistency of nitrogen compounds have been used to elucidate nitrogen’s fate in an urban environment. While reactive nitrogen commonly is associated to agriculture and hence to large areas, here we have compiled scientific literature on nitrogen budget approaches in cities, following the central role cities have in anthropogenic activities generally. This included studies that specifically dealt with individual sectors as well as budgets covering all inputs and outputs to and from a city across all sectors and media. In the available data set, a clear focus on Asian cities was noted, making full use of limited information and thus enable to quantitatively describe a local pollution situation. Time series comparisons helped to identify trends, but comparison between cities was hampered by a lack of harmonized methodologies. Some standardization, or at least improved reference to relevant standardized data collection along international norms was considered helpful. Analysis of results available pointed to the following aspects that would reveal additional benchmarks for urban nitrogen budgets: analysing the share of nitrogen that is recycled or reused, separating largely independent sets of nitrogen flows specifically between food nitrogen streams and fossil fuel combustion-related flows, and estimating the stock changes for the whole domain or within individual pools.
Effects of a combination of phytase and multi-carbohydrase enzymes in low-density corn–soybean meal based diets on growth performance and ileal nutrients digestibility of male broilers

Abstract A study was conducted to evaluate the effect of dietary supplementation of phytase and carbohydrase on growth performance and ileal digestibility of nutrients in broilers fed low-density corn–soybean meal-based diets. A total of 280 one-day-old Ross 308 male broilers were randomly assigned to 7 dietary treatments, with 4 replicates of 10 birds. Dietary treatments were (1) full nutrient specification without enzyme supplementation (positive control; PC), (2) diet with reduced nutrients as a phytase matrix (negative control; NC), (3) NC + phytase (500 FTU/kg diet), 4) NC + multi-carbohydrase (0.1 g/kg), (5) NC + phytase + multi-carbohydrase, (6) diet with reduced nutrients as phytase and multi-carbohydrase matrices; low negative control (LNC), and (7) LNC + phytase + multi-carbohydrase. Broilers fed either NC or LNC diets had lower body weight gain, the European production efficiency factor, and a higher feed conversion ratio than those fed PC diet (p < .01). Broilers fed LNC diet had lower dry matter (DM) and crude protein (CP) digestibility, and apparent ileal digestible energy (AIDE) than those fed PC diet (p < .01). Multi-carbohydrase supplementation on top of phytase-containing NC diets resulted in a similar effect on performance and digestibility of DM and AIDE in broilers compared with LNC diets containing phytase and multi-carbohydrase. Digestibility of CP was lower in NC + multi-carbohydrase groups than NC + phytase + multi-carbohydrase (p < .01). In conclusion, multi-carbohydrase was successful in improving broiler performance and nutrients digestibility in the diet based on the corn–soybean meal with lower nutrient density; thus, when supplementing it as a second enzyme in diets containing phytase, its matrix value should be considered for least-cost feed formulation. HIGHLIGHTS Phytase and carbohydrase matrix values should be considered when enzyme combination using in C-SBM diet. Carbohydrase improved broiler performance and nutrients digestibility in C-SBM diet with lower nutrient density. Cost-effectiveness use of enzyme combination in diets could reduce nutrient excretion.
First-line treatment with infliximab versus conventional treatment in children with newly diagnosed moderate-to-severe Crohn’s disease: an open-label multicentre randomised controlled trial

Objective In newly diagnosed paediatric patients with moderate-to-severe Crohn’s disease (CD), infliximab (IFX) is initiated once exclusive enteral nutrition (EEN), corticosteroid and immunomodulator therapies have failed. We aimed to investigate whether starting first-line IFX (FL-IFX) is more effective to achieve and maintain remission than conventional treatment. Design In this multicentre open-label randomised controlled trial, untreated patients with a new diagnosis of CD (3–17 years old, weighted Paediatric CD Activity Index score (wPCDAI) >40) were assigned to groups that received five infusions of 5 mg/kg IFX at weeks 0, 2, 6, 14 and 22 (FL-IFX), or EEN or oral prednisolone (1 mg/kg, maximum 40 mg) (conventional). The primary outcome was clinical remission on azathioprine, defined as a wPCDAI <12.5 at week 52, without need for treatment escalation, using intention-to-treat analysis. Results 100 patients were included, 50 in the FL-IFX group and 50 in the conventional group. Four patients did not receive treatment as per protocol. At week 10, a higher proportion of patients in the FL-IFX group than in the conventional group achieved clinical (59% vs 34%, respectively, p=0.021) and endoscopic remission (59% vs 17%, respectively, p=0.001). At week 52, the proportion of patients in clinical remission was not significantly different (p=0.421). However, 19/46 (41%) patients in the FL-IFX group were in clinical remission on azathioprine monotherapy without need for treatment escalation vs 7/48 (15%) in the conventional group (p=0.004). Conclusions FL-IFX was superior to conventional treatment in achieving short-term clinical and endoscopic remission, and had greater likelihood of maintaining clinical remission at week 52 on azathioprine monotherapy. Trial registration number ClinicalTrials.gov Registry (NCT02517684).
Implicit Teaching Strategies on Grammar Instruction: Students’ Prevailing Stance

Grammar teaching in foreign language education has been maintained by most theories as one thing playing a significant role in facilitating the process of learning to read, write, speak, and understand a foreign language. However, scholars label that role as controversial both in the research of second language acquisition (SLA) and language pedagogy. Thus, such condition results in a potential cause of confusion to teachers and students, then leads the researchers to a thoughtful theoretical debate on the topic of the way grammar should be taught: explicitly or implicitly. The aim of the present case study was to gain an insight into the prevailing stance of Indonesian English students on grammar teaching enrolled in a senior high school. To this end, a questionnaire as well as interview sessions were developed and validated based on one construct pair from SLA literature: explicit versus implicit instruction. The findings, in general, showed that the students were found to prefer implicit over explicit instruction. Nonetheless, the stance somewhat changed depending on the proficiency level of students. As an implication, this study supported Indonesian English students to maintain their stance on implicit teaching strategies on grammar instruction, regarding the help they can get in the process of natural acquisition of language.
EVALUATION OF EFFECT OF ZnO NANO-PARTICLES AND THEIR INTEGRATION WITH THE BIOCONTROL AGENT TRICODERMA HARZIANUM FOR CONTROL OF DAMPING OFF DISEASE CAUSED BY RHIZOCTONIA SOLANI ON TOMATO PLANTS

The soil borne fungus Rhizoctonia solani is the causative agent of damping-off disease that causes severe economic losses in several crops including tomato world wide. Currently, the Nano particles have become an accepted biocide, aimed to combat plant pathogens. However, ZnO nano particles has not been examined alone or in combination with the biocontrol factor Trichoderma harzianum against R. solani. Hence, experiments were conducted to determine the influence of ZnO nano particles (synthesized and commercial) alone or along with T. harzianumin protection of tomato plants against damping-off disease. All of the tested of ZnO NPs exhibited influential antifungal activity against R. solani. The most effective compound was the commercial ZnO NPs with concentration of 15 μg/mL. This antifungal activity was also appeared against T.harzianum. Germination of tomato seeds was not affected by ZnO NPs. However, growth parameters of tomato seedlings were affected. The treatment of soaking tomato seeds in ZnO nano particles suspension (15 μg/mL) for three days, then sowing them in compost inoculated with T. Harzianum and R. solani inoculums in addition to spray the ZnO nano particles suspension on the emergent tomato seedlings was the only one among the treatments that significantly proved a protection to tomato seeds and seedlings from the pathogen R. solani. These results showed that ZnO NPs could be used in combination with the biological factor T. harzianum as an effective resistance approach in tomato for control of damping-off disease.

Corresponding Author: Amal Saad-Hussein Department of Environmental and Occupational Medicine, National Research Center, Giza, Egypt Email: amel_h@hotmail.com Abstract: The current study investigated some possible effects of long-term use of mobile phones on the oxidative-antioxidants balance and its effect on the prostate. Twenty-eight eligible volunteers frequently use mobile phones and from the same socioeconomic status were enrolled in the study. They were examined according to the effect of time every two years for a follow-up period with four years. A detailed personal, occupational and medical questionnaire was completed for each participant through personal interviews. Total and free Prostate-Specific Antigen (PSA) levels, in addition to the levels of malondialdehyde, Total Antioxidant Capacity (TAC) and Zinc (Zn) were determined. At the end of the study, total and free PSA and MDA levels increased significantly compared to the baseline. Compared to the two years of use, total and free PSA level, free PSA/total PSA ratio, MDA and Zn levels were significantly increased after 4 years. In conclusion, the long-term use of cell phones may cause a redox imbalance characterized by increased oxidative stress that eventually affected the prostate gland.

Microstructure, extractability and physicochemical properties of shortfin scad (Decapterus macrosoma) bone collagen as influenced by acetic acid concentration

Collagen from shortfin scad (Decapterus macrosoma) bone was extracted using varying concentrations of acetic acid. Yields of extracted collagen were 1.01 ± 0.09% and 1.31 ± 0.07% for 0.5 M and 0.7 M acetic acids, respectively. The pH values of commercial collagen and shortfin scad bone collagen extracted using acetic acids (0.5 M and 0.7 M) were 6.52 ± 0.03, 4.99 ± 0.04, and 5.32 ± 0.01, respectively. The functional group analysis for collagen showed that the Amide A, Amide II and Amide III bands have been detected. The microstructure study showed that the isolated collagen had a porous fibril network. Maximum solubility for the commercial collagen was observed at pH 3, while the collagens extracted with 0.5 M and 0.7 M acetic acids were similar at pH 8. Meanwhile, the relative viscosities for all collagens indicated increasing values with increasing temperatures. In conclusion, the shortfin scad bone collagen showed potential for use as an alternative collagen. Although the values for shortfin scad bone collagen extracted by 0.5 M and 0.7 M acetic acids were lower than the commercial one, the collagens exhibited similar properties.
Clinico-Hematological Profile of Dengue Fever during the Monsoon of 2016 in Central Kerala

Background and objective: Dengue is one of the most common mosquito-borne viral infection involving newer areas, newer populations and increasing in magnitude after each epidemic in India. This study is aimed to study the clinico-hematological profile of patients with dengue fever during the monsoon of 2016 in a tertiary care teaching hospital. Materials and methods: A prospective study conducted in a tertiary care centre in Tiruvalla, Kerala from May 2016 to August 2016.A total of 236 adult patients who were positive for NS1 Antigen were further analyzed for their biochemical, hematological and clinical profiles.

This study compared teaching skill evaluations and professional disposition evaluations for candidates accepted and denied admission to an educator preparation program based upon GPA and testing requirements. The study sought to determine the relationship between academic and non-academic indicators and teaching skills. The data revealed academic indicators of GPA and test scores do not relate to teaching skills. A correlation was found between non-academic indicators, professional dispositions, and the teaching skills evaluation score. The results suggest professional dispositions may be a stronger indicator of success for admission to educator preparation programs and future licensure than GPA and test scores.
Effect of fly ash on the service life , carbon footprint and embodied energy 1 of high strength concrete in marine environment 2

6 Durability is one of the primary considerations in designing concrete structures in aggressive 7 environment. This paper presents a study of concretes containing fly ash as 30% and 40% of 8 the total binder in regards to service life, carbon footprint and embodied energy. A simple 9 deterministic service life estimation technique using the well-known Fick’s law was applied to 10 assess the service life of similar grade concrete mixes against the corrosion due to chloride 11 diffusion. The parameters needed to predict the service life of concrete were determined from 12 laboratory experiments. Compared to control concrete, fly ash concretes showed less chloride 13 diffusion which is considered as the dominant form of attack in reinforced concrete structures 14 in marine environment and thus the latter is more durable or have longer service life than the 15 former. Finally, this paper presents the application of life cycle assessment to measure carbon 16 footprint and embodied energy consumption saving benefits of the use of more durable fly ash 17 concretes in the aggressive marine environment. 18
Changes in Future Precipitation Mean and Variability across Scales

Changes in precipitation variability can have large societal consequences, whether at the short timescales of flash floods or the longer timescales of multi-year droughts. Recent studies have suggested that in future climate projections, precipitation variability rises more steeply than does its mean, leading to concerns about societal impacts. This work evaluates changes in mean precipitation over a broad range of spatial and temporal scales using a range of models from high-resolution regional simulations to millennial-scale global simulations. Results show that changes depend on the scale of aggregation and involve strong regional differences. On local scales that resolve individual rainfall events (hours and tens of kilometers), changes in precipitation distributions are complex and variances rise substantially more than means, as is required given the well-known disproportionate rise in precipitation intensity. On scales that aggregate across many events, distributional changes become simpler and variability changes smaller. At regional scale, future precipitation distributions can be largely reproduced by a simple transformation of present-day precipitation involving a multiplicative shift and a small additive term. The “extra” broadening is negatively correlated with changes in mean precipitation: in strongly “wetting” areas, distributions broaden less than expected from a simple multiplicative mean change; in “drying” areas, distributions narrow less. Precipitation variability changes are therefore of especial concern in the subtropics, which tend to dry under climate change. Outside the tropics, variability changes are similar on timescales from days to decades, i.e. show little frequency dependence. This behavior is highly robust across models, suggesting it may stem from some fundamental constraint. ∗Corresponding author; moyer@uchicago.edu Changes in future precipitation mean and variability across scales A PREPRINT

A STUDY ON OCCURRENCE OF GESTATIONAL DIABETES MELLITUS AND ITS CLINICAL MANAGEMENT

Early diagnosis of gestational diabetes mellitus is the key that may allow proper measures to be taken to make a satisfactory outcome of pregnancy. To determine the occurrence, association between certain factors, and GDM along with the diagnostic criteria and its clinical management. This prospective observational study was conducted on in-patients and out-patients of the obstetrics and gynecology department. The data was collected from subjects, their relatives, in and out patient’s clinical records. The results were summarized using frequency and percentage. The risk factors for GDM were analyzed using the Chi-square test. A total of 207 pregnant women were enrolled, and 89 were diagnosed with GDM. The occurrence of GDM was 43%. The known risk factors for GDM were identified as advanced age, overweight, obesity, and history of DM in first degree relatives had a significant association with GDM (P<0.05). Metformin was the most prescribed drug during all trimesters (3.3%, 7.8% and 31.4%) as compared with insulin (2.2%, 2.2% and 6%). This study finds the occurrence of GDM among pregnant women and also suggests the probable association between risk factors and GDM, which will contribute to improved management.
