Application of Information Computer-based Learning in Calculus Package Learning

- This study aims to determine the effectiveness of Information Computer Technology (ICT)-based learning packages focusing on calculus courses among college students, and to find a tested learning package model in the ICT-based learning of calculus. This study was developmental research which includes requirements analysis, designing learning packages, and evaluation of the learning package. Design research uses literature study, survey, application of learning packages, evaluation and content analysis. Overall, 35 college students of Department of Mathematics, Faculty of Mathematics and Science, Manado State University who take calculus courses were participated. Data were analyzed using descriptive analysis argumentative. After applied of this model, the results showed that there was increased in learning outcomes and level of understanding of the concept of differential and integral. It was influenced by the type of learning media that applied to the ICT-based learning package, namely the application program camtasia on power point programs. ICT-based learning was a contextual and based on the philosophy of constructivism learning so this study suggests that this model would become very well implemented in calculus. Therefore, more research on the effectiveness of ICT-based learning model is also needed for other majors. ( This finding has been presented in the 3 rd International Seminar on Quality & Affordable Education, November 2014, in University of Malaya, Kuala Lumpur )
ACTAS / PROCEEDINGS II SIMPOSIO INTERNACIONAL BILINGÜISMO

1. Theoretical framework Memory can be influenced by emotional stimuli in a great variety of ways. Some studies point out the difference between subjects low and high on a particular emotional characteristic (e.g. low and high anxious subjects or depressive ones), others refer the distinctive bias emotional material elicits either on implicit or explicit memory. For the purposes of this paper, the key theories about emotions and memory are those of Bower (1981) about mood congruency effects and of Ellis & Ashbrook (1988) with their resource allocation model about the role of emotions on the quantity of cognitive capacities. The effects elicited by emotions depend on the specific task the subjects have to perform. Memory research distinguishes between the emotional effects on implicit and explicit memory (e.g. Graf & Mandler, 1984; Roediger, Weldon & Challis, 1989). With implicit memory tests, the subjects are not explicitly directed to search their memory for previously learned material. For instance, they have to complete word stems with the first word that comes to their mind after being exposed to the experimental stimuli (primed). On the contrary, in explicit memory tests –free recall and recognition– there is a clear appeal to the stored material. Thus performance in implicit memory tests is a result of integration and in the explicit ones it is dependent on a deeper cognitive process, i.e., an elaboration which consists of integration but also involves developing connections to the schema and other contextual cues present at encoding. Some authors (e.g. Mathews et al., 1989) proposed that sometimes there is no bias for emotional
Growth , Yield , and Water Productivity Responses of Pepper to Sub ‐ Irrigated Planter Systems in a

A sub‐irrigated planter (SIP) is a container irrigation technique in which water is supplied to the crop from the bottom, stored in a saturated media‐filled reservoir beneath an unsaturated soil, and then delivered by capillary action to the root zone. The aim of this study was to optimize the water management and to assess the performance of this technique in terms of water use efficiency, soil moisture, and solute distribution in comparison with surface irrigation in a Mediterranean greenhouse. The experiment consisted of four SIP treatments, with a constant water level in the bottom reservoir in order to evaluate the effect of two different irrigation salinities (1.2 and 2.2 dS m−1) and two depths of substrate profiles (25 and 15 cm). The results showed that SIP is capable of significantly improving both water‐use efficiency and plant productivity compared with surface irrigation. Also, a 24% average reduction in water consumption was observed while using SIP. Moreover, SIPs with a higher depth were recommended as the optimum treatments within SIPs. The type of irrigation method affected the salinity distribution in the substrate profile; the highest salinity levels were registered at the top layers in SIPs, whereas the maximum salinity levels for the surface treatments were observed at the bottom layers. SIPs provide a practical solution for the irrigation of plants in areas facing water quality and scarcity problems.
A Chronology for a Massacre: Bayesian C-14 Analysis of the Archaeological Record from Sandby Borg, Öland

This thesis addresses radiocarbon (C-14) dating of bioarcheological finds from Sandby borg, an iron-age ring fort on the east coast of the Baltic Sea island of Öland, Sweden. Archaeological evidence suggests that Sandby borg was used during the European migration period and that its main period of usage was terminated by an isolated incidence of inter-personal violence where the inhabitants were killed or abducted. Radiocarbon dating of individual archaeological finds from this period becomes imprecise due to fluctuations of C-14 ratios in the atmosphere during the period 420-530 AD. In the work presented here, Bayesian modelling, whereby multiple finds as well as chronological information from typology and stratigraphy are combined into a statistical model is deployed, together with an estimate of the percentage of maritime products in the diet of individuals subjected to C-14 dating. The outcome of this analysis suggests that the usage ranges from 410-537 AD (95.4% probability) and that the lethal attack took place between the years 532 and 558 AD (95.4% probability). This latter dating interval is about 40-60 years later than what has been suggested from previous studies. The reliability of the modified chronology and its consequences for our understanding of the Sandby borg site is discussed, and some future directions of research are proposed.
Assessing English Proficiency at Advanced Level: Testers' Feedback to Teaching

To achieve beneficial washback effects of a public language test in the EFL classroom, communication between the testers and those involved in teaching and learning is desirable. This paper reports the results of the 2007 GEPT Advanced Listening and Reading Tests, based on which the learners' strengths and weaknesses are discussed in relation to the test construct. The GEPT Advanced Test is part of the five-level proficiency framework particularly developed for Taiwan's EFL learners. Those who master this level can communicate effectively and can handle academic or professional requirements. It is expected that university graduates who have majored in English can demonstrate this level of proficiency. However, only an average of 20% of test-takers have been able to pass the test annually, which is below the benchmark (30%) set by the GEPT research committee. Apparently, there is a gap between the test designers' expectation and the reality for the advanced learners. Therefore, the important questions are why such a difference exists and how it may be minimized or even resolved in the future. This paper, by providing the assessment information, intends to render assistance in addressing these questions. Ultimately, it is hoped that a conscious feedback loop between the teaching and testing of English can
A Field Survey on the Types of Videos and Learning Approaches deemed appropriate for the 21st Century Teaching and Learning

Undisputedly, rapidly changing technologies have introduced many unprecedented challenges to almost every sphere of the people’s lives. For one, the educational realm has witnessed many changes made to the teaching and learning process to ensure students can learn with greater efficacy. Against this backdrop, this paper discusses the findings of a field study based on an online survey involving 91 students of Sultan Idris Education University, Tanjung Malim, Perak, Malaysia. The researchers used Google Form, which is a free survey development tool, for the development of online questionnaire of the survey. The main aims of this field study are as follows: (a) to determine the type of learning video deemed relevant to the 21st century learning, (b) to determine the teaching approach of lecturers as preferred by students, and (c) to determine the relevant teaching approach for subjects that entail logical thinking. Data collected were analysed descriptively, yielding a number of interesting findings. Firstly, 90% of the respondents (n = 82), which constituted an overwhelming majority, stated that they would prefer voice-recorded video and whiteboard animation as the appropriate learning aids. Secondly, at 60% (n = 55), more than half of the respondents indicated that lecturers should use a whiteboard and a portable visualizer to help improve their teaching process. Finally, a significant number of the respondents, at 81% (n = 74), indicated that the teaching of subjects requiring logical thinking (e.g., programming subject) would be best carried out with the use a whiteboard and a portable visualizer. Collectively, these findings suggest that novel interactive learning tools are indispensable in the teaching and learning process, especially for subjects that require higher order thinking skills, in this new millennium.
Fluid supplements and playing surfaces effect on tennis players during simulated match at high temperature

The aim of this study was to compare the effect of consuming various fluid supplements while playing tennis on different playing surfaces on selected physiological and biochemical variables during simulated match at high temperature < 34 °C. Ten University level male tennis players, underwent eight treatment trials against the ball machine for 90 minutes, which had predetermined set protocol on Clay Surface (CS) and Hard Surface (HS); and consumed 1800 ml of different fluid supplements in each trial, namely Plain Water (PW), High Carbohydrate Drink (H-CHO), High Electrolyte Drink (H-ED) and Carbohydrate-Electrolyte Drink (CHO-E) in counterbalanced way. Two way repeated measures ANOVA were employed. It was concluded that CHO-E is the best drink on HS whereas on CS, CHO-E and H-ED are considered as best drink followed by H-CHO and PW respectively. This study shows that playing tennis on HS brings more physiological and biochemical changes than the CS at high temperature.
Piper sarmentosum attenuates dexamethasone-induced hypertension by stimulating endothelial nitric oxide synthase

Reduced endothelial nitric oxide (NO) synthesized by endothelial nitric oxide synthase (eNOS) in the vasculature is a feature of endothelial dysfunction. Dexamethasone causes secondary hypertension by inhibiting eNOS activity. Piper sarmentosum is an herb with anti-hypertensive effect. The aim of this study was to evaluate the antihypertensive effect of aqueous extract of P. sarmentosum (AEPS) in dexamethasone (Dex)-induced hypertensive rats. A total of 30 male Sprague Dawley rats were divided into five groups including control, AEPS (500 mg/kg/day, orally), Dex (20 μg/kg/day, subcutaneously), Dex (20 μg/kg/day) + AEPS (500 mg/kg/day) and Dex (20 μg/kg/day) + captopril (40 mg/kg/day, orally). Blood pressure was measured using tail-cuff method at baseline and fortnightly thereafter. The rats were sacrificed and the serum was collected to quantify the amount of NO after 28 days of treatment. Aortic samples were homogenized for measurement of eNOS mRNA expression, protein level and activity. Treatment of Dex-induced hypertensive rats with AEPS lowered systolic blood pressure (P < 0.001) and diastolic blood pressure (P < 0.01), increased eNOS mRNA expression (P < 0.01), eNOS protein (P < 0.01), eNOS activity (P < 0.05) and NO level (P < 0.05). In conclusion, AEPS reduces the blood pressure of Dex-induced hypertensive rats as it shows positive effects on eNOS and NO production.
Effect of transitions in standards on the value predictive power of financial information of listed Oil and Gas Firms in Nigeria

Corporate entities are under obligations to provide information about the financial position and performance and are expected to be in accordance with laid down standards and other statutory regulations. Studies showed that several reports of financial manipulations exposing firms which proved to be profit-making became insolvent, this poses a big question as to whether reporting under GAAP is value relevant. This study examined the influence of relevance of financial information on the value of listed Oil and Gas firms in Nigeria before and after the adoption of IFRS. The study was an expost-facto research using all the listed six (6) petroleum marketing firms as published by the Nigerian Stock Exchange (NSE) on 1st March, 2019 as sample subjects for a period of twelve (12) years, which was 6 years (2006-2011) prior adoption and 6 yeras (2012-2017) after adoption of IFRS. Data obtained from published audited financial statements already validated by external auditors were used and analyzed using multiple regression with the aid of Stata/IC 11.0 software. The study discovered that financial information (Earnings Per Share (EPS), Book Value Per Share (BVPS) and Operating Cash flow Per Share (OCFS)) significantly affect value of listed oil and gas companies in Nigeria before and after the adoption of IFRS, and that the predictive power of financial information improved after the adoption of IFRS (Pre: Adj. R 2 = 0.46, Wald (3) = 22.03, p < 0.05; Post: Adj. R 2 = 0.66, F (3, 32) = 23.64, p < 0.05; Combined: Adj. R 2 = 0.50, F (3, 32) = 11.57, p < 0.05). The study concluded that transition in accounting standards has improved the predictive powers of earnings, operating cash flow and book value of asset of companies. Standard setters should continually update the standards and firm managers should improve on the level of compliance to improve the quality of the financial information.
EFFECT OF REAL SECTOR OUTPUT ON TAX REVENUE IN NIGERIA

Tax revenue has remained the most reliable and controllable source of revenue to governments all over the world. This is however not the case in Nigeria as tax revenue accounts for a small proportion of government revenue. This study therefore investigated the influence of real sector output on tax revenue in Nigeria . Ex-post facto research design was adopted using validated macro data obtained for the period 1981-2017. Various tests including descriptive statistics, trend analysis, and stationary tests using Augmented Dickey Fuller (ADF) test were conducted. The ARDL bound test was employed to determine the existence of long run relationship between the variables. The study concluded that real sector output, controlling for inflation rate and exchange rate, has significant positive influence on tax revenue generation in Nigeria (Adj. R 2 = .603, F (33,3) = 417.033, p < . 05) . Furthermore, exchange rate and inflation rate had significant moderating effect on tax revenue in Nigeria. Also, the result of the granger causality test revealed non-existence of bi-directional relationship between real sector output and total tax revenue. The study recommended that government should intensify effort on stimulating growth in the real sector of the economy in order to achieve sustainable increase in tax revenue. In addition, government’s macroeconomic policies on exchange rate and inflation rate should be undertaken in a way to optimize tax revenue.
IFAD Research Series 57 Unlocking the Potential of Rural Youth: The Role of Policies and Institutions

This paper presents a framework to analyse the political economy of rural youth policy and institutions’ opportunity space, with a quadrant that measures the extent to which rural youth are a priority in policies and institutions versus the extent to which the government has the capacity to effectively implement rural youth policies. It asks under what conditions policies focused on rural youth employment and opportunities are likely to be developed, and, once developed, implemented. We utilize quantitative and qualitative data gathered from various sources in order to make a determination about favourable conditions for effective policies for rural youth, looking at the origins and complexity of policy responses in an array of specific cases. That perspective is then followed by a discussion about what attributes contribute to making good policies for rural youth, drawing on theoretical literature and case studies. Such policies should aim to be democratic and participatory, cross-sectorial and transversal, coherent and coordinated. They should also be research-/evidence-based, adequately budgeted and financed, and effectively monitored and evaluated. Finally, and importantly, such policies must also be gender sensitive/gender responsive, recognizing the different opportunities and challenges faced by young men and young women, so that related policies and programmes attempt to redress existing gender inequalities.
Pioneer paper: Value-added components derived from whey

Technological developments have shifted most of the North American whey supply away from the animal feed/fertilizer category into a wide array of value-added products used in the food and nutraceuticals industry. Early products such as roller dried whey powder had poor functionality and limited food product application. Technological advances in evaporation and spray drying, along with the development of demineralization and electrodialysis technology, led to further improvements in functionality in whey-based powders. The next generation of products consisted primarily of whey protein concentrate and isolate prepared primarily through the development of membrane technology, particularly microfiltration. Within the last decade, improvements have provided cleaner separations and improved membrane performance and durability. In addition, nanofiltration and microfiltration have provided additional tools for whey processors for producing and modifying the functionality of whey-based ingredients. These technological developments have diversified ingredient selection and expanded their use in frozen desserts, snack foods, beverages, processed meats, fermented dairy products, processed cheese foods and spreads, baked goods, and confectionary. More recently, emphasis has been placed on the isolation of the major proteins in whey for use as gelation agents (β-lactoglobulin) and nutritional supplements (α-lactalbumin). In addition, good progress has also been made in the isolation, characterization, and production of bioactive components from whey, now termed nutraceuticals. The components of interest include both major and minor proteins, enzymes, peptides, lipids/lipoproteins, vitamins, and minerals. Selected components of this group have been shown to reduce hypertension, sarcopenia, cancer, and osteoporosis and to modulate of immune function. This paper will highlight the development and application of value-added products derived from whey, with emphasis on the food and nutraceuticals industry. Future technological challenges could include the isolation, purification, and characterization of pharmaceutical components from whey.

OFFLINE TESTS WITH THE NSCL

Rare isotopes are produced at the National Superconducting Cyclotron Laboratory NSCL by projectile fragmentation at energies of≈100MeV/u. TheNSCL has successfully used linear gas stopping cells for more than a decade to decelerate projectile fragments to the keV range; first for experiments at low-energy and more recently for reacceleration. A novel reverse-cyclotron has been constructed by the NSCL based on a superconducting sectored-cyclotron magnet and LN2-cooled He gas to confine and slow down the fragments. Efficient stopping is predicted even for light ions that are difficult to thermalize in linear gas cells. The thermalized ions are transported to the center by a radial RF-carpet system, extracted through the yoke with an ion conveyor and accelerated to <60 keV for delivery to users. Measured field profiles have confirmed field calculations. The cryogenic beam-stopping chamber has been installed inside the magnet. The RF ion-guiding components have been tested successfully offline and are being prepared for low-energy ion-transport tests inside the magnet.

Elasticity of MgSiO3 orthoenstatite

The single-crystal elastic moduli of the MgSiO 3 orthoenstatite end-member have been measured by Brillouin spectroscopy at ambient conditions. The aggregate elastic moduli at 1 atm are KS = 107.6(15) GPa and μ = 76.8(7) GPa, for the adiabatic bulk modulus and shear modulus, respectively. These values are in excellent agreement with the results of previous acoustic studies of synthetic MgSiO3. Comparison of our results with pressure-volume ( P-V) measurements do not support the presence of a change in the P-V trajectory of orthoenstatite at ~4 GPa, as suggested previously on the basis of X-ray measurements to 8.5 GPa. The effects of chemical composition on the elasticity of orthopyroxenes are well represented by the variation of compressional and shear velocities with density, which exhibit well defined trends for both synthetic and natural samples. *Current address: Department of Civil Engineering and Geological Sciences, University of Notre Dame, Notre Dame, IN 46566-0767, U.S.A. 0003-004X/99/0004–0677$05.00 677 American Mineralogist, Volume 84, pages 677–680, 1999
