Adaptive Computer Assisted Assessment of free-text students' answers: An approach to automatically generate students' conceptual models

Teachers aim to transmit their knowledge to students so that they acquire certain accepted and shared concepts. However, what students actually understand is, in many cases, something completely different. Students build their own conceptual models as a network of interrelated concepts depending on their particular background and emotions. In this work, a new procedure to automatically generate students' conceptual models from their free-text answers is presented. Moreover, teachers can visualize, at any time, the generated conceptual models to discern their students? faulty or incomplete knowledge in order to organize more efficiently the agenda of their courses; and, students can organize their study, i.e. review which concepts have already assimilated and, which ones are still missing or are wrongly connected to other concepts. The procedure has been implemented in the Will Tools that consist of: Willow, a free-text ACAA system; Willed, an authoring tool; Willoc, a configuration tool; and COMOV, a conceptual model viewer in which several representations have been used to show the conceptual models.
Anomalous Financing Choices with the Change of Industrial Policy : The Case of Taiwan

This paper examines whether firms’ financing choices are anomalously affected by the change of institutional environment. From the data of Taiwanese listed firms, the estimated results indicate that policy incentives for R&D investment and facility procurement affect firms’ financing choices diversely in industries. Besides, firms decide appropriate leverage level depending on the incentives and benefits they can obtain from different policy periods. Specifically, change of the institutional environment causes firms to make active financing decisions that may distort firm value. To reduce risk of market and systemic failure, we suggest that government should consider curtailing disproportionate subsidies or incentives as a way to avert excessive intervention. On the other hand, firms should measure the pros and cons of obtaining benefits of policy incentives and avoid changing their decided financing strategy that may be more a loss than gain in the long run.
COMPARISON BETWEEN HYDROPONIC AND AEROPONIC SYSTEMS FOR LETTUCE PRODUCTION

The main objective of this research is to study the effect of aeration on preventing the root problems by comparing the hydroponic system with aeration to the aeroponic system. The obtained results indicated that the root length increased from 17.17 to 19.13 cm with increasing flow rate from 1.0 to 2.0 L h in hydroponic system and increased from 17.45 to 19.56 cm with increasing flow rate from 0.5 to 1.5 L h in aeroponic system. The fresh and dry mass of shoot and root were increased in aeroponic system over those of hydroponic system. The total nutrients uptake values were higher in aeroponic system than those in hydroponic system. The average nitrogen, phosphorus, potassium, calcium and magnesium uptakes were 3.29, 1.25, 2.46, 0.43 and 0.44 %and 2.13, 0.82, 1.81, 0.32 and 0.40 % for aeroponic and hydroponic system, respectively. The average nitrate content was 155.52 and 113.73 mg plant for aeroponic and hydroponic system, respectively. The average nitrate protein ratio was 1.91 and 4.16%, for aeroponic and hydroponic system, respectively. The average water use efficiency was 4.75 and 2.93 kg m for hydroponic and aeroponic system, respectively.
THE FLIPPED LEARNING MODEL IN ONLINE EDUCATION FOR SECONDARY TEACHERS

The online-based model known as “flipped learning” raises new challenges that are different from those of face-to-face teaching. The flipped learning model enhances the active and autonomous learning of students, changes the relationships between them and with the teacher, and encourages innovation within the learning process. The following paper presents a descriptive, poll-based study after having implemented the model in the Curricular design course offered in two different departments, Mathematics and Technology and Computer Science, as part of the Master’s Degree program in Secondary Education Teacher Training, taught online by the International University of La Rioja (UNIR). For this purpose, we have designed a learning model with a series of stages based on the events proposed by Gagné for the design of a teaching unit. In order to analyze the impact that the model has on student performance, the final grades obtained by the students are collected after individually designing a didactic unit, as required to demonstrate their learning, analyzing the difference between the control group and those participating in the designing experience. The results revolve around several axes, such as student satisfaction, the training they received, the perceived usefulness of the training received, the evaluation of the entire training process as it was carried out, and the performance achieved. This model ensures that the student is satisfied with and finds the usefulness of the training received, attains better academic performance and fosters very positive attitudes among the students as a whole.
European Conference on Information Systems ( ECIS ) Summer 10-6-2011 VALUE-BASED PROCESS IMPROVEMENT

For years, “improving business processes” has been and is the primary business priority of IT. In business process management (BPM), common criteria to evaluate the improvement of a process are time, costs, customer satisfaction and output quality. In contrast, the management of companies focuses on increasing the company’s value, using a value-based management approach, which is hard to be linked to these criteria. A value-based process improvement can alleviate this drawback by incorporating value-based management into the area of BPM. In this paper we introduce, based on the design science paradigm, an approach that is suitable for the value-based improvement of processes. Demonstrating the feasibility and the advantage of our approach, we show its applicability within a real world scenario and evaluate it by comparing it to a competing work in the field of valuebased process management.

Changes in Paraoxonase 1 activity and concentration of conjugated dienes in connection with number of metabolic syndrome components

Objective: Paraoxonase 1 is an antioxidant enzyme with a variety of physiological roles – one of them is the inhibition of LDL (low-density lipoprotein) lipid peroxidation and inactivation of LDL-derived oxidized phospholipids. The aim of this study was to investigate the PON1 activity and levels of conjugated dienes in precipitated LDL (CD/LDL) in subjects, who fulfill different numbers of metabolic syndrome (MetS) criteria. Design: Cross-sectional study Settings: 4th Department of Internal Medicine, 1st Faculty of Medicine, Charles University and General University Hospital Prague Material and methods: The population under study consisted of 354 Caucasian subjects (188 females/166 males) divided into 6 groups according to the number of presented components of metabolic syndrome. All groups were age matched. The activity of paraoxonase 1 and concentration of conjugated dienes in precipitated LDL (CD/LDL) were both assessed spectrophotometrically. Results: The activity of PON1 was significantly decreased in subjects with all 5 components of MetS in comparison with those with 0 to 3 components of MetS (p < 0.05). The concentrations of CD/LDL were increased in subjects with 4 or 5 components of MetS compared to subjects with 0-3 components of MetS (p < 0.001). Conclusion: As was shown in this study, the levels of PON1 are extensively affected by the concentration of HDL-C and ApoA1. PON1 activity is depressed and CD/LDL levels are increased mainly in subjects who fulfill all five criteria of MetS.
Adaptive Fuzzy-PI Control for Speed ’ s Tracking in a Leisure Electrical Vehicle

This paper deals with a comparison study between different kinds of controllers based on a speed tracking problem inside an electrical vehicle using an axial-flux permanent-magnet traction motor. In fact, the framework of these works is the control of the powertrain of electric vehicles which is a great challenge to ensure driving comfort. To do so, the vehicle’s performances are carried out using an established simulation platform implemented on MatlabSimulink environment. Then, obtained results are compared for the three synthesized controllers. It has been found that required speed levels are reached with a clear advantage of the adaptive Fuzzy-PI controller versus the PI and the fuzzy counterparts, from the points of view of rise and selling times.
Parasites as a Viability Cost of Sexual Selection in Natural Populations of Mammals

Sexual selection in mammals has resulted in the evolution of sexual size dimorphism (SSD), with males usually being the larger sex. Comparative analyses indicate that the evolution of SSD is associated with the evolution of male-biased mortality, suggesting a possible causal link between the two. Here, we use a comparative approach to investigate the possible role of parasites in generating this relation. We show that there is a robust association between male-biased parasitism and the degree of sexual selection, as measured by mating system (monogamous or polygynous) and by the degree of SSD. There is also a positive correlation, across taxa, between male-biased mortality and male-biased parasitism. These results are consistent with the hypothesis that parasites contribute to the observed association between SSD and male-biased mortality.
Integrin α 10 β 1-selected Equine MSCs have Improved Chondrogenic Differentiation , Immunomodulatory and Cartilage Adhesion Capacity

Cell therapy based on multipotent, adult mesenchymal stem cells (MSCs) is a promising method for the regeneration of cartilage tissue and treatment of osteoarthritis in both humans and animals. For safe and effective use of MSCs as therapeutic agents, quality control of the isolation and expansion methods as well as the final MSC product is of key importance. The aim of this study was to evaluate integrin α10β1 as a novel MSC biomarker to attest identity, purity and potency of MSC preparations. We found that MSCs, isolated from equine adipose tissue (AT) and selected using an antibody directed to integrin α10, expressed the stem cell markers CD44, CD90 and CD105, differentiated to chondrocytes, osteocytes and adipocytes and demonstrated immunomodulatory capacity as judged by suppression of T-cell proliferation and expression of PGE2. In addition, we found that integrin α10-selected equine AT-MSCs showed higher chondrogenic differentiation capacity, in pellet mass cultures, compared to unselected MSCs. Moreover, the integrin α10-selected fraction of MSCs showed significantly higher adhesion capacity to cartilage defects in ex vivo osteochondral explants compared to unselected MSCs demonstrating a higher ability of the α10-enriched MSCs to home to an osteochondral damage. Taken together, the results show that integrin α10β1 can identify a homogenous population of multipotent equine AT-MSCs with a high chondrogenic differentiation and immunomodulatory potency as well as homing capacity. Thus, we conclude that integrin α10β1 is a biomarker that can ensure quality, potency and consistency of MSC preparations for cartilage repair.
Ethnopharmacological investigation and antibacterial evaluation of the methanolic extract of Asparagus racemosus ( Shatavari )

Plants are the base of sophisticated traditional medicine systems including Ayurvedic, Unani and Siddha. Phytochemical analysis of Asparagus racemosus revealed that numerous compounds of plants traditionally used for medicinal purposes have several therapeutical properties. The result of the phytochemical studies revealed the presence of saponins, tannins, alkaloids, steroids and other biochemicals. Saponins, tannins and alkaloids are well known for their antibacterial properties. Experiments demonstrating the pharmacological properties of saponins have aroused considerable clinical interest in these substances. The concentrations of the plant used were 25 mg ml, 50 mg ml and 100 mg ml respectively. At these concentrations, the extract inhibited the growth of Escherichia coli, Pseudomonas aeruginosa and Vibrio parahaemolyticus and produced percentage inhibition ranging from 72.4–86.5 %. The antibacterial activity demonstrated by the plant extract may due to the presence of the phytochemicals present in the plant.
The Impact of Chinese Interbank Liquidity Risk on Global Commodity Markets

We show how interbank liquidity risk in China impacts the commodity futures risk premium across the world through commodity financing deals. Investors import commodities, collateralize them, and invest high-yielding shadow banking products to exploit the high-interest rate differences under capital controls and financial frictions in China. We reveal that the Chinese commercial banks act as market makers of the shadow banking system in China, and they use the interbank market to resolve the associated maturity mismatch. If maturity mismatch risk intensifies, the demand for commodities as collaterals would reduce. To sum up, we empirically show both predictive and contemporaneous relations when interbank liquidity risk in China increases, measured by the 3-month and the overnight interbank loan rates, the commodity futures risk premium decreases due to contractions in the hedging demands for commodity financing deals. Our findings are robust with regard to other channels not related to commodity financing deals.

Buried paleo-channels on the New Jersey continental margin : channel porosity structures from electromagnetic surveying

We report on a marine electromagnetic (EM) survey across two portions of the New Jersey continental margin that have been previously shown to contain buried paleo-channels. The EM method used provides bulk porosity estimates to depths of around 20 m below the sea ̄oor and is thus able to place porosity constraints on the nature of the channel in®ll and the contrast in physical properties across the channel boundaries. Our data show that a key condition for the channels to have an electrical signature is that they incise an underlying regional unconformity, R, thought to represent a subaerially eroded surface, exposed during the late Wisconsinan glaciation. Channels that cut R are seen through increases in apparent porosity. Another seismically imaged channel sequence, which lies within the outer-shelf sediment wedge sequence above R, does not have an electrical signature, indicating that the sediments above and below the channel boundaries have similar physical properties. q 2000 Elsevier Science B.V.

IN VITRO CHARACTERIZATION OF SELECTED INDIGENOUS RHIZOBACTERIAL STRAINS AS BIOCONTROL AGENT OF BACTERIAL WILT DISEASE ON CHILI

Bacterial wilt caused by Ralstonia solanacearum is the important dangerous diseases in chili. Until now this disease has been difficult to control; while the bacteria attack the xylem vessel they cannot be reached by any bactericide. Biocontrol is potential for controlling this disease. One group of important biocontrol agents is the plant growth promoting rhizobacteria (PGPR). Based on in planta screening method, we have found 13 indigenous rhizobacterial strains from healthy chili’s rhizosphere, which have the ability to control bacterial wilt and to increase growth and yield of chili. This research is aimed at characterizing the direct mechanisms of selected indigenous rhizobacterial strains as biocontrol agents of R. solanacearum in vitro. The physiological characters of indigenous rhizobacterial strains as biocontrol agents had been observed, including production of antibiotic, siderophore, HCN, haemolysine, protease, and biosurfactan. For root colonization rifampicin mutants of indigenous rhizobacterial strains had been the results of in vitro analysis showed that those selected rhizobacterial strains had various physiological characters as biocontrol agents. Not all biocontrol tested characters have been produced by indigenous rhizobacterial strains. Only RZ2.1AP4 strains showed the positive on 3 characters. All indigenous rhizobacterial strains produced biosurfactant but only Pseudomonas hibiscicola strain RZ1.1AG4 showed the highest viscosity. All rifampicin mutants of indigenous rhizobacterial strains have colonized chili roots on rhizoplane and in the root tissues (endophyte) from nursery until 9 days after planting. RZ2.1AP2 and Klebsiela michiganensis strain RZ1.3AG4 showed the highest bacterial population on chilli roots. The bacterial population was higher in root tissue (endophytes) than on the root surface (rhizoplane) from seedling stage until 9 days after transplanting.
Temporal distribution of cabbage seedpod weevil [ Ceutoryhncus obstrictus ( Coleoptera : Curculionidae ) ] on different canola cultivars and potential use of early maturing canola as trap crop

Seasonal fluctuation of cabbage seedpod weevil (CSPW) [Ceutorhynchus obstrictus (Coleoptera: Curculionidae)] on four canola cultivars and potential use of early maturing canola lines as trap crops for controlling CSPW were determined in separate field experiments conducted at Alabama A&M University’s Winfred Thomas Agricultural Research Station in Hazel Green in 2007-08 and 2008-09 cropping seasons. Winter canola cultivars, Jetton, Banjo, Celcius and Explorer adapted to southeastern conditions, were used in the experiments. Results showed no significant differences in the number of CSPW among test varieties. However, infestation levels varied with date of sampling. Freezing temperatures of -3C on three consecutive days in 2007 (April 7-9) resulted in low populations of cabbage seedpod weevil in 2007 and 2008 growing seasons, compared to those in previous years. Based on our results, early maturing lines are a promising as trap crop for the control of CSPW on canola.
Proposed Framework with Comparative Analysis of Access Control & Authentication based Security Models Employed over Cloud

Cloud computing is a booming technology defined as abstraction of different computing resources as like hardware or software provided over a network in the form of a specific service. It’s a rapidly emerging technology in the market from quite some time now and considerable research work related to its security perspective are going on it. Security of data present over a cloud and accessible to CSP has been considered as a major issue in recent times. These types of services could end up with attacks or threats like malicious insider attack, Man in middle attack and dictionary attacks to name a few. Apart from this providing security to data revolving around the cloud environment is governed with access control security provisions or models implemented over a cloud. In the past, several authors have presented various access control and user authentication models or schemes which are being used over cloud based environments and were either providing secure access control or authentication based security. Some proposed frameworks also provide combination of both access control and authentication based security models which were not that efficient or secure. Here in this paper, initially major access control models and authentication schemes proposed earlier for a cloud environment are analyzed and compared over selected characteristics. Secondly, a Multi-Security Level Based Authentication and Access Control Model (i.e. MLBAAC) is proposed here followed by its hypothetical analysis on above selected characteristics.
EVALUATION OF BREAD WHEAT GENOTYPES IN IRRIGATED AND RAINFED CONDITIONS USING BIPLOT ANALYSIS

This study was carried out in 2015-2016 and 2016-2017 seasons under supplemented irrigation (IC) and rainfall conditions (RC) of Diyarbakir in Turkey, was to determine high adaptive yielding with high quality bread wheat genotypes. The obtained data were analyzed using variance and GGE-biplot analysis methods, and the genotypes (G) were evaluated for drought tolerance indices. The average grain yield of two year ranged from 5820 to 6950 kg ha on rainfall conditions and 7880 to 9050 kg haunder supplemented irrigation conditions. The GGE biplot graph showed that G3, G6 and G21 were best genotypes for grain yield. Although G23 did not have the highest grain yield, it was determined that it represented the most stable line. Furthermore, G12 and G16 were determined as suitable genotypes for irrigated conditions and G21 for rainfall condition. It was determined that mean productivity (MP), stress tolerant index (STI), geometric mean productivity (GMP) and harmonic mean (HM) parameters were related with Yp (supplemented irrigation yield) and Ys (rainfall condition yield). Also, yield index (YI), drought resistance index (DRI), yield stability index (YSI) was related with Ys. In the study concluded that the lines G6, G12, G16 and G21 could be candidates for registration.
CORRELATION OF ALBUMIN / CREATININE URINE RATIO ( ACR ) CHANGES ON MORTALITY OF SEPTIC PATIENTS IN HAJI ADAM MALIK GENERAL HOSPITAL MEDAN

Introduction : Microalbuminuria has proven to be a predictor of organ function failure in septic patients. Microalbuminuria assessed by calculating ratio of urine albumin/ creatinine could be used as a simple, noninvasive to assess prognosis and predict mortality in early septic patients. Method : Thirty one septic patients weretaking urine samples for examination of albumin levels in the urine using urine albumin/ creatinine ratio (ACR). Patients also were observed for a maximum of 28 days to assess mortality. Result : Mortality of septic was found in 21 subjects (67.7%). Pneumonia was the most common source of infection (58.1%). Changes in ACR (p=0.02) and ACR II value (p=0.016) had a significant correlation with mortality in septic patients. In the contrary, no significant correlation was found between age, sex, vital signs, and source of infection with mortality of septic patients (p> 0.05). Hb values, platelets, ad random blood sugar, procalcitonin,urea and creatinine also did not have a significant correlation with mortality in septic patients (p> 0.05). Conclusion : This study suggested association between changes in ACR and ACR II with mortality of septic patients. The higher the value of ACR II would resulted in higher the patient mortality.
