Patterns of Interaction in a Computer Conference Transcript

An analysis of the interaction patterns in an online conference from a distance education graduate course was conducted, using an approach that focused on the transcript’s interactional and structural features. A new tool for transcript analysis, the TAT (Transcript Analysis Tool), was used to analyze interactional features, while structural elements suggested by social network theory were examined. Analysis of the patterns of interaction in the conference showed interaction was variable, and that while all participants were engaged, intensity and persistence of participation were unequal among individual participants in several ways. The TAT showed the proportions of ve major types of sentences in the transcript, corresponding to dierent modes of interaction (questions, statements, reections, engaging comments, and quotations/citations). The ndings showed that the TAT seemed to relate usefully to other work in this area, and that social network principles were valuable in the analysis of conference interaction.
Comparative Study of Pre-Service Teacher Education Programme at Secondary Stage in Bangladesh, India, Pakistan and Sri Lanka.

The present research work has studied and compared the different issues of pre-service teacher education programme in India, Sri Lanka, Bangladesh and Pakistan. The data were collected from 24 principals, 88 teacher educators and 157 student teachers from institutions and universities where Bachelor of Education (B.Ed.) course were. The data were also collected from secondary sources. The descriptive analysis was carried. One year duration of B.Ed. programmers were found inadequate in India, Bangladesh and Pakistan. Graduation was the minimum qualification for admission in B.Ed. course in all countries except Sri Lanka. In some universities of India and Bangladesh, entrance test was conducted for admission into this course. There were regulatory bodies in all the four countries for maintaining the norms and standards of this course. The curriculum and syllabus of B.Ed. course was not revised during last five year in Bangladesh, Pakistan and Sri Lanka. This course is more dominated in theory than practicals in all the four countries. The respondents of India, Bangladesh and Pakistan expressed that the duration should be increased to at least two years. Key words: Teacher education, secondary teachers, student teachers, pre-service teacher education programme
Robustness of Food Processing Classification Systems

Discrepancies exist among food processing classification systems and in the relationship between processed food intake and dietary quality of children. This study compared inter-rater reliability, food processing category, and the relationship between processing category and nutrient concentration among three systems (Nova, International Food Information Council (IFIC), and University of North Carolina at Chapel Hill (UNC)). Processing categories for the top 100 most commonly consumed foods children consume (NHANES 2013–2014) were independently coded and compared using Spearman’s rank correlation coefficient. Relative ability of nutrient concentration to predict processing category was investigated using linear discriminant analysis and multinomial logistic regression and compared between systems using Cohen’s kappa coefficient. UNC had the highest inter-rater reliability (ρ = 0.97), followed by IFIC (ρ = 0.78) and Nova (ρ = 0.76). UNC and Nova had the highest agreement (80%). Lower potassium was predictive of IFIC’s classification of foods as moderately compared to minimally processed (p = 0.01); lower vitamin D was predictive of UNC’s classification of foods as highly compared to minimally processed (p = 0.04). Sodium and added sugars were predictive of all systems’ classification of highly compared to minimally processed foods (p < 0.05). Current classification systems may not sufficiently identify foods with high nutrient quality commonly consumed by children in the U.S.
Spatial and temporal distribution of macroalgal assemblages associated with the invasive Asparagopsis armata on intertidal rocky shore in Azores

Rapid globalization and the increasing trends of trade, travel, and transport in recent decades have accelerated marine biological invasions. The Rhodophyta Asparagopsis armata is considered one of the most invasive species in European subtropical and temperate waters. A. armata, first recorded in the Azorean Archipelago in 1928, is now well established and very common in all Azorean islands, mainly between 5 and 20 m depth. Although having a wide distribution in the archipelago, little is known about its spatial and temporal variation and its impact on the invaded littoral communities. The present study aims to fill this gap and define spatial and temporal variations of the seaweed assemblages associated with the invasive Asparagopsis armata on low intertidal rocky shore. Three locations along the south coast of São Miguel Island were compared (Caloura, Lagoa and São Roque) in a monthly sampling between November 2016 and April 2017. According to our predictions, of temporal and spatial variability in the number of macroalgal taxa, there was an interactive effect between location and time. Environmental factors were proposed to account for this. A positive correlation between the abundance of Asparagopsis armata and the high diversity was found in Caloura, contrasting the venerable generalization of more diverse communities are more resistant to invasion. However, further studies taking into account its higher biomass peak (late spring) are needed in order to confirm this positive correlation.
Differential gene expression analysis of the Coix transcriptome under PEG stress

Drought stress severely affects plant growth and crop yield. Coix lachryma-jobi L (Coix) commonly known as Job’s tears, is a member of the grass family in the tribe Maydeae. To understand the transcriptome dynamics and explore the important drought resistant genes during drought stress in coix seedlings, in this study,YiLiao 5, with good resistant drought was taken as the experimental material. The results showed 92,865 unigenes were detected and the average gene length was 737.85 bp, the N50 was 1,26bp. A comparison of the treatment and the control samples revealed that 1,128 differentially expressed genes (DEGs) were expressed, including 662 and 466 genes that were up-and down-regulated, respectively. According to the Gene Ontology (GO) database, among biological processes the metabolic process group was the largest group (14,908 genes, 24.28%) and contained high frequency of differentially expressed genes (352 genes, 24.22%). The DEGs are involved in 170 metabolic pathways. The plant hormone signal transduction and starch and sucrose metabolism were relatively obvious. Some DEGs and proteins were found, such as response to abscisic acid genes, 9-cis-epoxycarotenoid dioxygenase, some Transcription factors (TFs), protein serine/threonine phosphatase, late embryogenesis abundant protein (LEA). Eight genes analyzed by Quantitative Real-time PCR (qRT-PCR) confirmed the transcriptome results. Overall, this study had done the transcriptome sequencing and established a genomics database of Coix for the first time. Meanwhile the results also provided a molecular basis and theoretical resource for mechanistic studies on drought resistance in Coix.
Performance Analysis of Solar Combined Ejector-Vapor Compression Cycle Using Environmental Friendly Refrigerants

In this study, a new model of a solar combined ejector-vapor compression refrigeration system has been considered. The system is equipped with an internal heat exchanger to enhance the performance of the cycle.

Measuring Service Performance, Student Satisfaction and its Impact on Student Retention in Private, Post-Secondary Institutions

With an ever growing assortment of educational options, students seek institutions that will provide for them a unique educational experience that they will remember for a life time. In addition, the present student is a customer seeking an educational program that will prepare him/her for a successful career and gainful employment. Since institutional budgets are developed based upon projected enrolments, it is becoming crucial for private institutions to retain the students they recruit. This situation has created a need for continued research in the area of student satisfaction and student retention. A reduction in student numbers, therefore, leads to a reduction in budgeted funds available to operate, maintain, and grow a private institution. The purpose of this study is to add additional contributions to the body of work on service quality, satisfaction, and student retention in higher education. This study attempts to show the relationship between service expectations, service performance, student satisfaction, and salient student retention constructs hoping to shed new light on the research question: Is there a significant relationship between service quality, student satisfaction and student retention in higher education? The results show that there are significant relationships between service performance and student satisfaction that will aid private, post-secondary institutions to predict and measure student satisfaction and retention.

Genetic and biological characterization of nine Streptococcus salivarius subsp thermophilus bacteriophages

Summary - Nine bacteriophages of Streptococcus salivarius subsp thermophilus isolated from different fermentation accidents, with different geographic origins, were compared according to their genomic structures and growth characteristics. Their genomes are linear, double-stranded DNA, with complementary cohesive ends. They belong to one group and are c1assed into 2 closely related strains. The phages of the same strain show the same restriction pattern with BamHI, EcoRI, Hindlll and Pvu II. The bacteriophages 81.2 and A 1.1 representative of the strain 1 and strain 2 respectively were characterized and compared according to their morphology, growth characteristics, restriction maps and DNA homology. They belong to Bradley's group B. The optimum concentration of 25 mM was determined for phage infections requiring calcium ions. One-step growth studies show that the latent period is 25 min for both A1.1and B1.2;their burst size is 88 and 56 particles per infected cell, respectively. Their genomes are 36.2 ± 0.5 and 35.6 ± 0.5 kbp in length, respectively. The restriction maps of these genomes are constructed. Cross-hybridization experiments showed that the 2 bacteriophages are clossly related. Using Southern blot hybridization, no homology was detected between the DNA of various bacterial strains, te, strains sensitive or resistant to phage infections, and the B1.2DNA, indicating that these bacteria are not Iysogenic for these phages. bacterlophage 1 Streptococcus sa/ivarlus subsp thermophllus 1 restriction map 1 DNA homol

Beneficial Effects of Antioxidants on Oxidative Stress and Diabetes-Induced Experimental Nephropathy

Summary A study was undertaken to evaluate the effect of antioxidants such as β-carotene, vitamin C and vitamin E on oxidative stress and streptozotocin-induced diabetic nephropathy in rats. The rats were rendered diabetic by a single intraperitoneal injection of Streptozotocin (50 mg/kg), which was assessed by determining the blood glucose levels. Serum TBARS and plasma GSH levels were estimated to assess the oxidative stress. Furthermore, parameters like BUN, serum creatinine and urinary albumin were determined to assess the effect of antioxidants on diabetic nephropathy. Treatment with β-carotene (10 mg/kg/day i.p.), vitamin C (10 mg/kg/day i.p.) and vitamin E (40 mg/kg/day i.p.) showed significant ameliorative effects on oxidative stress and nephropathy in diabetic rats. Moreover, β-carotene was found to be more potent in the amelioration of oxidative stress and diabetic nephropathy when compared with vitamin C and vitamin E that may be due to its potent antioxidant property.
Access to Healthcare vis-à-vis Women’s Reproductive Health in Cameroon

All over the world several million women die each year and 90% of them in developing countries from pregnancy and childbirth related causes. Nearly all of these are preventable yet in Cameroon this is far fetched. This study questions why women die from these causes? Is it due to government neglect and / or womens callous attitude toward pregnancy and/or the patriarchal control of women? Are healthcare facilities lacking or rudimentary inadequately staffed and / or expensive? This study argues that limited access to healthcare facilities drains womens reproductive health down the spiral in Munyenge-Cameroon Via open-ended semi-structured interview guide questions data was solicited from 40 pregnant women between 15-45 years. Interviews followed a topic guide and exploited interviewees different views focused on different themes to elicit reflective accounts which enabled respondents talked freely about highly personal issues which rekindled their memories on reproductive health problems due to limited access to healthcare facilities. All interviews were tape-recorded in Pidgin English (a lingua franca) to eschew questions being misconstrued if asked in English and this tremendously enhanced data reliability and validity. The data was transcribed into English to ease data interpretations explanations discussions and analyses. The findings provide a comprehensive picture of healthcare service mismanagement of facilities mens control of women due to socio-cultural tenets financial vulnerability of women hence limit their access to health care facilities.

On the Mechanism of International Technology Diffusion for Energy Technological Process CCEP Working Paper 1405 December 2014 *

International diffusion of energy-saving technologies has received considerable attention in recent energy and climate economics studies. As a helpful methodological complement to the existing large-scale CGE/IAM–based modelling for energy and climate policy studies, this paper contributes to a transparent analytical model for an economically intuitive exposition on the fundamental mechanism of international technology diffusion for energy technological growth. We first develop an efficiency-improving vertical innovation model where energy technological progress is specified as an improvement in primary energy use efficiency. Then a variety-expanding horizontal innovation model is presented where energy technological progress is described as an expansion of energy technology variety. We show that in both models there is a cross-country convergence in the growth rate of energy technology in a long-run balanced growth path, but the absolute levels of energy technology tend to diverge due to cross-country differences in indigenous innovation efficiencies and knowledge absorptive capacities. An economy with a stronger capacity of absorbing foreign knowledge diffusion and undertaking indigenous research tends to have a higher level of energy technology. * This paper replaces an earlier version published in June 2014.
Arduino-Uno based mobile data logger with GPS feature

Lightning activity correlates with the formation of thunderclouds which increase the atmospheric electric field (AEF) between the cloud and the earth. Observations of the development of the AEF will allow the prediction of lightning activities close to a particular location. In research and development, the data logger plays an important role to observe and collect data from AEF sensors. The data logger must be reliable and effective. High investment costs are involved in acquiring a data logger, and choosing a suitable data logger is not easy. Institut Voltan dan Arus Tinggi (IVAT) is develeloping AEF sensor. Along with that sensor development a data logger development is also required. In this paper, a mobile data logger is developed by using Arduino-Uno. This mobile data logger is equipped with a GPS module, which provides accurate positioning in the collection of data. Laboratory and field tests were carried out to observe the performance of the mobile data logger system. The results showed that the developed data logger works properly.

Determinants and impact of cloud computing implementation in the public sector

This study empirically analyses which determinants influence the public sector to implement cloud computing, as well as the effect to performance. Drawing upon the theory on the technology-organization-environment and IS success model, the study hypothesizes that technological, organizational, environmental and human factors can be viewed as the reasons for cloud computing assimilation within the agencies in the Malaysian public sector. Our proposed research model and hypotheses are tested using SEM-PLS and survey data from a sample of 169 agencies in the Malaysian public sector. Our empirical analyses lead to several key findings. All second order factors of Technological, Organizational, Environmental and Human factors affect cloud computing implementation in the Malaysian public sector. Implementation of computing by the agencies significantly affect to IT operational effectiveness. Together, these article offer empirical insights into how cloud computing implementation is influenced by the contextual factors in the Malaysian public sector.
Forcasting Portofolio Value-At-Risk for International Stocks, Bonds, and Foreign Exchange Emerging Market Evidence

This paper uncovers the nature of conditional correlations between and volatility spillovers across bond, stock and foreign exchange in Indonesia, Malaysia, the Philippines, and Thailand. Using various multivariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models, it finds the evidence of highly persistence in the conditional variance, volatility spillovers across assets, and time-varying conditional correlations in all markets. It also provides Value-at-Risk forecast based on the estimated models. Assuming normal distribution, the tests suggest that incorporating volatility spillovers and time-varying conditional correlations does not help in providing Value-at-Risk forecasts. Assuming t distribution, the tests suggest that incorporating volatility spillovers provides better VaR forecasts. Keywords: conditional correlations, volatility spillovers, VaR forecast
