Published: September 2016

Este documento, explora algunas de las consideraciones teóricas y empíricas más importantes acerca del Resale Price Maintenance (RPM) el cual se ha convertido no solo en un problema de orden económico, sino legal. Para ello, el tema se abordará en dos aspectos. En primer lugar, se describen las implicaciones teóricas del RPM, y por otra parte, se muestra la evidencia empírica encontrada a partir de una exploración documental. De manera que la reflexión planteada sugiere que las restricciones verticales evitan el free riding tanto en fabricación como en distribución, dada la tentación de aprovechar el esfuerzo de otros comercializadores en gastos de publicidad, entrenamiento de asesores, reputación de la marca, inversiones en salas de exhibición, etc., en beneficio propio, además de reducir la incertidumbre.

Sinogram Restoration for Sparse Projections Applied to Noisy Data in Ultrasound Tomography
Authors: Widodo Catur Edi
Published: September 2016

In some cases the number of projections in a set of tomography data is limited. This can be seen from their sinogram. If this kind of data is reconstructed, the image produced will be deteroited. In order to overcome this problem an algorithm for restoring the incomplete sinogram  has been developed in previous work. In that work the developed algorithm was tested using ideal data from Shepp-Logan panthom. In this paper the same algorithm is applied to restore incomplete and  noisy data in ultrasound  tomography. The phantom used in this study is a concrete cylinder with a diameter of 10.62 cm. Inside  cylinder there are 6 holes with a diameter of 2 cm each. These holes were filled with various materials. The phantom were scanned in ultrasound tomography scheme and the resulted sinogram then reconstructed with and without sinogram restoration. Using contrast to noise ratio (CNR) indicator the reconstructed image with sinogram restoration is better than that without sinogram restoration.
Experiment on Laser Speckle Imaging of Apples Using A CMOS Camera
Authors: Shiddiq Minarni
Published: September 2016

Laser Speckle Imaging recently has become a promising tool to assess fruit quality and can be applied in fruit sorting. It is a non-destructive, optical method which uses light scattered of fruit surface after illuminated by laser light. Laser speckle imaging methods use He-Ne laser or diode laser as the light source yet both lasers have differences in performance and price. Diode lasers are more preferable due to their efficiency, low cost, small and compact, and varied wavelength.  In this research, an optical system which consisted of a laser source and a CMOS camera was used for Laser Speckle Imaging.  A 632,8 nm He-Ne laser and a 650 nm diode laser were used, their performances were compared. The samples were two kinds of apples, Red Delicious and Fuji, five samples for each cultivar. The laser light was expanded using a beam expander hence illuminated on the apple surface at 30o angle.  A monochrome Thorlabs CMOS camera with camera lens was used to record the speckle patterns of the apple surface. Both lasers were kept at the same laser power by Neutral Density Filters. ImageJ software was used to calculate the gray value of the speckle pattern for each sample, the speckle gray values were compared for different laser light sources and apple types. The results showed that there is a significant difference in gray value level between both apples. Higher maximum gray values were found on the Fuji apples compared to the Red Delicious apples which were about 21.7 % when using He-Ne laser and 18.3 % when using diode laser.  Higher maximum gray value for Fuji apples could be due to their rounder shape, firmer skin and flesh, they scatter more light.  The curvature and the firmness of the fruits affected the gray value level. For each apple type, there was a slight difference in maximum gray values for both laser sources. Higher gray values were obtained when using diode laser compared to the He-Ne laser, 22.0 % difference for Fuji apples and 25.2 % difference for Red Delicious apples. These could be because of the less coherence, wider bandwidth, and irregular beam shape of the diode laser that it scatters more light and suppresses speckles.
Evaluation of TLCD Damping Factor from FRF Measurement Due to Variation of the Fluid Viscosity
Authors: Son Lovely
Published: September 2016

Tuned Liquid Column Damper (TLCD) has become an alternative solution for reducing low frequency vibration response of machines and structures. This is not surprisingly that the damper has simply structure and low maintenance cost. The main disadvantage of using TLCD is the complexity in controlling TLCD damping factor experimentally. Theoretically, damping factor can be controlled by adjusting the orifice dimension. However, this method is time consuming and not appropriate conducted in the real application. A more simply method for adjusting TLCD damping factor is by varying the fluid viscosity. This research is aimed to evaluate the effect of fluid viscosity to the damper performance. Two DOF shear structure with TLCD is used as the experimental model. Several TLCD fluids with different viscosity are evaluated. Evaluation of TLCD damping factor due to variation of the fluid viscosity is conducted by comparing the Frequency Response Function (FRF) obtained from the experimental data.
Application of Short Time Fourier Transform and Wavelet Transform for Sound Source Localization Using Single Moving Microphone in Machine Condition Monitoring
Authors: Rusli Meifal
Published: September 2016

The paper discusses means to predict sound source position emitted by fault machine components based on a single microphone moving in a linear track with constant speed. The position of sound source that consists of some frequency spectrum is detected by time-frequency distribution of the sound signal through Short Time Fourier Transform (STFT) and Continues Wavelet Transform (CWT). As the amplitude of sound pressure increases when the microphone moves closer, the source position and frequency are predicted from the peaks of time-frequency contour map. Firstly, numerical simulation is conducted using two sound sources that generate four different frequencies of sound. The second case is experimental analysis using rotating machine being monitored with unbalanced, misalignment and bearing defect. The result shows that application of both STFT and CWT are able to detect multiple sound sources position with multiple frequency peaks caused by machine fault. The STFT can indicate the frequency very clearly, but not for the peak position. On the other hand, the CWT is able to predict the position of sound at low frequency very clearly. However, it is failed to detect the exact frequency because of overlapping.

Authors: Sutikno Sigit
Published: September 2016

This paper presents an application of satellite remote sensing techniques to detect and to analyze the spatial changes as well as quantify the shoreline change in Rokan estuary, Riau Province, Indonesia. Coastal zone of Rokan estuary, a place through which Rokan River flows into Malacca Strait is dynamically changed because of the hydrodynamic nature and high sediment transport in downstream of Rokan River. By integrating modern techniques of remote sensing and GIS (Geographic Information System), the rates of shoreline change would be easily and quickly determined for a regional area. Landsat satellite images were used with a combination of histogram thresholding and band ratio method for shoreline change detection for last 14 years from 2000 to 2014. The shoreline data then were adjusted for serving as an input for GIS tool to estimate the erosion and deposition rates. The statistical method called as LRR (Linear Regression Rate) in DSAS (Digital Shoreline Analysis System) was used in this study. The results of this study present shoreline changes map of Rokan estuary for last 14 years. Quantitatively, the shoreline of Rokan estuary is dynamically changed over a time because accretion rate is very high. The accretion rates in Halang, Barkey, and Serusai Island within 14 years are 67 m/yr, 53 m/yr, and 114 m/yr respectively.This occurs because
First Principle Calculation of Electronic, Optical Properties and Photocatalytic Potential of CuO Surfaces
Authors: Ahmad Faozan
Published: September 2016

We have performed DFT calculations of electronic structure, optical properties and photocatalytic potential of the low-index surfaces of CuO. Photocatalytic reaction on the surface of semiconductor requires the appropriate band edge of the semiconductor surface to drive redox reactions. The calculation begins with the electronic structure of bulk system; it aims to determine realistic input parameters and band gap prediction. CuO is an antiferromagnetic material with strong electronic correlations, so that we have applied DFT + U calculation with spin polarized approach, beside it, we also have used GW approximation to get band gap correction. Based on the input parameters obtained, then we calculate surface energy, work function and band edge of the surfaces based on a framework developed by Bendavid et al (J. Phys. Chem. B, 117, 15750-15760) and then they are aligned with redox potential needed for water splitting and CO2 reduction. Based on the calculations result can be concluded that not all of low-index CuO have appropriate band edge to push reaction of water splitting and CO2 reduction, only the surface CuO(111) and CuO(011) which meets the required band edge. Fortunately, based on the formation energy, CuO(111) and CuO(011) is the most stable surface. The last we calculate electronic structure and optical properties (dielectric function) of low-index surface of CuO, in order to determine the surface state of the most stable surface of CuO.
Synthesis of Novel Nano-Strawberry TiO2 Structures with the Aid of Microwave Inverter System: Growth Time Effect on Optical Absorption Intensity
Authors: Shah Athar Ali
Published: September 2016

A novel anatase TiO2 with nanostrawberry-like structure with high porosity has been synthesised on ITO, with the aid of microwave power in a very short duration of 6 minutes. The growth of these novel TiO2nanostructures on ITO is attained stoichiometrically by using ammonium hexafluoro titanate, Hexamethylenetetramine, and Boric acid as precursor, capping agent, and reducing agent, respectively. Optical absorption intensity and thickness of these nanostructure layers can be varied by the growth time. A highly porous, 2.25 µm thickest layer has been successfully synthesised on ITO, and the average diameter of these nanostructures was found approximately 70±2.5nm. These highly porous nanostructures are expected to be good candidate for photocatlysis applications and efficient photovoltaic performances of dye sensitised solar cells.
Effect of Concentration Ratio of Precursor-Surfactant Solution on The Performance of Boron-doped ZnO Nanotubes Dye Sensitized Solar Cells
Authors: Andika Gusyeri
Published: September 2016

Boron doped zinc oxide (ZnO) nanotubes have successfully been grown using seed-mediated hydrothermal method at various concentrations of precursor-surfactant solution. The growth of ZnO nanotubes was carried out at a temperature of 90°C for 8 hours and a drop in temperature to 50°C for 16 hours. In this study, the effect of concentration ratio of precursor-surfactant was evaluated. Samples were characterized using UV-Vis Spectroscopy, X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray (EDX). UV-Vis spectra of the samples showed that the ZnO nanotubes were grown on the Flourine Tin Oxide (FTO) and the strong absorption occurred in the wavelength range of 300-400 nm, which is typical spectrum for hexagonal-nanostructure. XRD patterns showed five diffraction peaks at 2θ = 32.05°, 34.5°, 36.35°, 47.75° and 56,9°. The analysis of EVA Diffrac Plus confirmed the peaks were represented to the lattice of (100), (002), (101), (102), and (110) respectively. FESEM images of the samples showed the hexagonal-shaped ZnO nanotubes with an average diameter of 50-340 nm and an average thickness of 1.2 - 4.4 μm observed for all samples. Uniformity the size and shape of ZnO nanotubes become higher as concentrations of ZNH decreased. The EDX spectra of the samples showed the percentage of weight of Zn, O, and B was 69.35%, 21.60% and 4.76% respectively, while the percentage of their atoms was 33, 06%, 42.08% and 13.71% respectively. The B-doped ZnO nanotubes solar cells were fabricated by arranging a sandwich structure, consisting of the FTO, ZnO nanotubes, dye, electrolyte and platinum thin film. I-V characteristics of cell were carried out under irradiation of 100 mWcm-2 halogen lamp. The I-V curves produced the highest efficiency from the cells utilizing the B-doped ZnO nanotubes with their concentration ratio of precursor-surfactant of 0.1 M : 0.04 M as the active material, which was 0.352%. This value is much higher than that of pure ZnO nanotube based DSSC of 0.05%.

The Critical Load Measurements of Pineapple Leaf Fibre Reinforced Polyester Composite Using Single Edge Notched Beam (SENB) Testing
Authors: Dahlan Hendery
Published: September 2016

Pineapple leaf fibre has potential as reinforcement in composite material due to their advantages such as renewable fibre and abundantly available. Some studies have been conducted relating to their mechanical properties using tensile, impact and bending testing. However the analysis of crack propagation in pineapple leaf fibre reinforced polyester composite is still limited. In this paper, the main attention is therefore the critical load leading to crack propagation in the composite material for two different fibre orientations. The crack propagation is investigated using single edge notched beam (SENB) testing. The composite material was manufactured by hand lay-up with two different nonwoven fibre orientations i.e. 0o/90oand +45o/-45o. Then, five different initial crack lengths are given in experimental specimen. The result reveals that increasing initial crack length will decrease the value of critical load for both fibre orientations. Furthermore, the fibre orientation influences the critical loading. In general the critical load leading to crack propagation for composite with +45o/-45o orientation has higher value than composite with 0o/90o orientation. It can be concluded that the composite material with +45o/-45o orientation has good resistance to the crack growth.
Compressive Load Effect on Electrical Properties of Carbon Composite
Authors: Putri Namari Nuning Anugrah
Published: September 2016

Contrary to its name, the “lead” in pencil is predominately made up of combination of graphite and clay or polymer, hence it can be considered as carbon composite. It has been proven that the more amount of carbon, the greater Young Modulus will increase and vice versa. Some researches on electric property of carbon composite also have shown that pencil drawn can be treated as a strain gauges and chemiresistors on paper. It means that in pencil's lead, the mechanical and electrical properties are related to one another. In this study, we applied a compressive load on pencil's lead and measured the effect on its resistivity. The results show that the resistivity will decrease while the strain will increase.
Synthesis of Electrospun Nanofibers Membrane and Its Optimization for Aerosol Filter Application
Authors: Rajak Abdul
Published: September 2016

Nanofibers membranes were synthesized using electrospinning method for air filtration application. Polyacrylonitrile (PAN) with three different concentrations as the polymeric matrix of the nanofibers membrane is used. In the aerosol filtration, the pressure drop is one of the most important parameters, which is determined by the membrane characteristics. One of the parameters that influence the characteristics of membrane is concentration of polymer solution, in which it will determine the diameter of fiber. In this study, the relation between the PAN concentration and the pressure drop in air filtration test was examined. Three different concentrations of PAN solution (6, 9, and 12 wt.%) were employed under the same process parameters of electrospinning. The fiber diameter distribution of each membrane was measured from its scanning electron microscope (SEM) image. The three concentrations resulted in significant different effect to the pressure drop that proved the existing correlation between the polymer concentration and the air pressure drop.

Authors: Handayani Ari
Published: September 2016

Ion implantation is widely used for surface treatment to modify the near surface properties of materials especially semiconductors without changing their bulk properties. In this work an investigation on the effect of implantation by Ti-ion on the mechanical properties and the wet corrosion of the high Cr and Ni content FeCrNi alloy was performed. Because of its superior properties this alloy is also well known as super alloy and often used as structure material in nuclear reactors. The alloy was fabricated at BATAN in Bandung containing of 55.98 wt.% Fe , 23.46 wt.% Cr, 18.23 wt.% Ni and small amount of other metal elements, was fabricated in BATAN Bandung. The alloy sample was subjected to Ti-ion implantation in an ion generator with theoretical doses varied between 0.89x1016, 2.68x1016, 3.58x1016 and 10.75x1016 ion/cm2respectivelly. The hardness measurement was conducted with Vickers method and the corrosion resistance test was carried out in the borax acid (HBO3) environment. The microstructure of the material after implantation was characterized and analyzed by means of the Scanning Electron Microscopy (SEM) equipped with the Energy Dispersive X-Ray Detector (EDX) while the surface crystal structure was idenfied using X-Ray Diffraction (XRD). The result showed that the Ti implantation improved the surface hardness when the dose was higher than 3.58x1016 ion/cm2, while the corrosion resistance increased abruptly at all ion doses. However, no microstructure change could be observed on the cross section. A thin layer which is indicated by BSE image contrast was observed in the top most surface. Analysis on the EDS spectrum revealed that the layer could be considered to be the titanium oxide elucidating the increasing of hardness and exceptionally higher resistance to wet corrosion.

Authors: Bandriyana B.
Published: September 2016

Effect of b-quenching of Zr-2.5Nb-0.5Mo-0.1Ge alloy used for advanced fuel cladding material of Pressurized Water Reactor (PWR) was investigated. The aim of this research isto improve the mechanical and corrosion properties through modificationof the alloy with regard to high reactor burn up. The quenching process was conducted by heating the sample at temperature of 950 oCand soaking 2.5 hours,followed by quenching in water at room temperature and then continued with annealing process at 500 and 600oC. The change of hardness and oxidation resistance were characterized using optical microscope and scanning electron microscope (SEM). The effect on the oxidation resistance was investigated by the high temperature oxidation test using the MSB (Magnetic Suspension Balance) at 700 oC for 5 hours. The hardness increased from 217 VHN to 265 VHN after quenching due to grain refinement and precipitation hardening. The oxidation rate followed the typical parabolic growth characteristic. The formation of thin layer was considered to be a stable oxide ZrO2that influenced the oxidation characteristic and increasing the hardness of the alloy.
Comparison Of Uncertainty Methods For Pipe Deflection Calculation
Authors: Wahanani Nursinta Adi
Published: September 2016

Reliability of pipe structure is one aspect to be considered in reactor safety analysis. MSC NASTRAN is a computer code that can be used to calculate pipe deflection for reliability evaluation. MSC PATRAN can be used to generate input for this code. Uncertainty evaluation needs to be done in the input variable to understand uncertainty range in the analysis results. A computer code for evaluating structure reliability has been developed in our previous study. The code has implemented latin hypercube sampling (LHS) to assess uncertainty in the input variable, such as load and modulus of elasticity. In this study, comparison of two uncertainty methods, i.e. simple random sampling (SRS) and LHS, was carried out for the developed software. The comparison was subjected to pipe deflection calculation using 100 samples. Comparison analysis shows that LHS method produces a robust mean of variance for all sample size. The results also confirm that variance of pipe deflection using LHS is smaller by 3% than SRS one. It can be concluded that LHS is appropriate to be implemented for uncertainty analysis in the developed code.

The 3D thermal-hydraulics analysis based on Computational Fluid Dynamics (CFD) has a role to analysis more detail the reactor safety, especially for pebble-bed typed High Temperature Reactor (HTR). A realistic pebble arrangement becomes a challenge to be modeled based on the Simple Cubic (SC), Body-Centered Cubic (BCC) and Face-Centered Cubic (FCC). Furthermore, CFD calculation could utilizes laminar model as well as turbulence model such as ,  and Reynold stress model (RSM). Therefore, the objective of this reseach is to analyze the effect of turbulence model on temperature and coolant velocity distribution using FCC on pebble-bed typed HTR as well as investigation of the turbulence models. The comparison shows that all models are acceptable for HTR-10 case with the difference by the range of 0.03-0.33% for the temperature parameters, in which the minimum different is obtained by  model.

 
The Effect Of Hydrazine Addition On The Formation Of Oxygen Molecule By Fast Neutron Radiolysis
Authors: Sunaryo G.R.
Published: September 2016

Hypothetically speaking, hydrazine could suppress the oxygen formation as a major of corrosion initiator. In this work, we developed a calculation model to understand the effect of hydrazine addition toward the oxygen under PWR condition. Our great interest is to study whether this strategy would also be effectively applied in PWRs[P1] . In the present work, the effect of hydrazine on suppressing the molecule oxygen under neutron irradiation is described.  The simulation was done by using FACSIMILE.  The variation dose applied assuming a batch system and at high dose ~104 Gy s-1.  Three different temperatures were applied, which are room temperature, 250 and 300 oC at two system oxygenated water, which are aeration and deaeration. At room temperature, for deaerated condition, added hydrazine under a range of 10-6 – 10-4 M into primary coolant were not effective to suppress  O2 form since the effect was similar as in the pure water system since for 10-3 M hydrazine addition, a large produce of O2 were obtained. In reverse, for deaerated condition, hydrazine concentrate about 10-3 M can suppress O2 form significantly, while hydrazine add in the range between 10-6 – 10-4 M is again confirmed to be the same as in pure water system. For high temperature, at 250 and 300 oC, the results showed that in deaerated condition, hydrazine addition can suppress  O2  form proportionally to its concentration while in aerated condition, hydrazine add with concentration of 10-6 and 10-5 M were not effectively to suppress O2  form, a slightly decrease of O2 occurred due to the addition of 10-4 M hydrazine and 10-3 M of hydrazine can suppress the formation of O2 significantly. [P2]

Published: September 2016

O objetivo deste artigo é analisar uma prática pedagógica na qual alunos de um quarto ano do Ensino Fundamental viveram um processo criativo mediado pela leitura da literatura procurando compreender até que ponto, a produção imaginária é cultivada na escola. O referencial teórico adotado foi a perspectiva Histórico-Cultural de desenvolvimento humano que considera que quanto mais rica for a experiência social e cultural da criança, mais possibilidades existirá de criação e de imaginação, portanto, cabe a escola possibilitar meios de desenvolvimento da criação aos seus alunos. O episódio recortado para análise faz parte da coleta de dados de uma das pesquisadoras durante o percurso de mestrado. Metodologicamente, a pesquisa de cunho qualitativo documentou as relações de ensino vividas por uma professora e seus alunos através de audiogravação e anotações em diário de campo. Também foram tomados como dados os planos de ensino da professora e as atividades produzidas pelos alunos. Conclui-se que o ato de criação e o lugar do imaginário como condição essencialmente humana, pela mediação da linguagem, pode ter lugar na escola ao mesmo tempo em que as práticas pedagógicas podem constituir-se como novas formas de participação das crianças na cultura.
Praca jako obowiązek a praca jako źródło satysfakcji. Studium historyczne roli i znaczenia pracy w dziejach Polski (po 1945 roku)
Authors: Kamosiński Sławomir
Published: September 2016

The paper presents an analysis of the ethical, political and economic aspects of human
work within two Polish historical periods – the years of the People’s Republic
of Poland and after 1989. The starting point for the analysis was the assumption that
every time period, each age, leaves a mark on man’s work.
Analysis of the People's Republic of Poland period gives an opportunity to
consider human work understood as a duty and right of every human guaranteed by
the Constitution of 1952. Questioning the principles ruling the labour market by the
ideologists of the People’s Republic of Poland and, as a consequence, the politicization
of labour, resulted in the collapse of the work ethic. Work, as it was at that
time a commonly available good, lost its value, regarded as the source of life satisfaction,
and thus became ridiculed.
After 1989, in relation to the de-politicization of the Polish labour market, the
employee became active in searching for a job. The phenomenon of unemployment
resulted in competition on the labour market and the employer was thus given the
opportunity to freely select a group of employees. As a result, the employer became
a distributor of a ‘rare commodity.’ That, in turn, led to the situation where the approach
of employers towards employees turned into the employer's diktat. It is the
employer who determines the conditions of employment, standards of work and
place of work. A lack of alternative that many employees face often makes them
accept the dictated conditions of work. What is more, in Poland we deal with the
insufficiently developed participation of employees in managing the enterprises,
which is an effect of breaking off the bilateral dependency of employee and employer.
Developing a Positive Emotion–Motivated Tai Chi (PEM-TC) Exercise Program for Older Adults With Dementia
Authors: Yao Lan , Giordani Bruno , Alexander Neil B.
Published: September 2016

Exercise, particularly Tai Chi, has many known benefits, especially in reducing fall risk. However, exercise studies have tended to exclude older adults with dementia (OAD), who may be at high fall risk but have difficulty participating in formal exercise programs. This paper describes development and feasibility testing of a Tai Chi fall risk reduction exercise protocol, the positive emotion–motivated Tai Chi (PEM-TC) program for OAD, and explores strategies that facilitate their participation in and adherence to exercise programs. Preliminary data indicates that difficulties in delivering exercise to OAD may be eased by using the Sticky Hands Tai Chi teaching technique. Family members may have the optimum advantage in using Sticky Hands because of established emotional connections with their OAD.
Graduate students’ opinions about entrepreneurship as an employment opportunity
Authors: Juračak Josip , Tica Marko
Published: September 2016

One of the most unwanted and unavoidable consequences of the economic recession is the high rate of unemployment. Graduate students in Croatia are faced with lack of employment possibilities, and for some of them the self-employment looks like a good solution. In this paper, we investigate attitudes and intentions of graduate students at the University of Zagreb Faculty of Agriculture regarding to selfemployment. Most of the surveyed students are in the age between 21 and 25 years, and they have already got some kind of knowledge about entrepreneurship during the formal education. In addition, majority of them have the experience of part-time jobs. The Theory of Planned Behaviour (TPB) model was used to find out to which extent students’ attitudes and experience influence their expressed self-employment intentions. The results revealed that Zagreb students’ scores are close but somewhat lower than the same scores found in the comparable study from Australia. This goes for the investigated variables: (1) previous entrepreneurial experience (PEE), perceived desirability of selfemployment (PDSE), perceived entrepreneurial self-efficacy (PESE) and self-employment intentions (SEI). It was found that the score on the PEE is significantly related to scores on the PDSE (p=0.000), and PESE (p=0.000), which means that the experience positively influence respondents’ attitudes on self-employment and self-efficacy. There is also a statistically significant difference in the on the SEI with respect to the PDSE (ANOVA F=9.804, p=0.000): respondents that consider self-employment more desirable expressed higher intention to perform it. The PDSE was found as the most influencing model variable in regards to the self-employment intention. The results points out the importance of previous experience, role models and positive attitudes towards self-employment in the process of the entrepreneurship development in young, educated population.

Roles and student identities in online large course forums: Implications for practice
Authors: Baxter Jacqueline Aundree , Haycock Jo
Published: September 2016

The use of large online discussion forums within online and distance learning continues to grow. Recent innovations in online learning such as the MOOC (massive open online course) and concomitant growth in the use of online media for the delivery of courses in traditional campus based universities provide both opportunity and challenge for online tutors and learners alike. The recognition of the role that online tutors and student identity plays in the field of retention and progression of distance learners is also well documented in the field of distance learning. Focusing on a course forum linked to a single Level 2 undergraduate module and open to over 1,000 students, this ideographic case study, set in a large distance learning university, uses qualitative methodology to examine the extent to which participation in a large forum can be considered within community of practice (COP) frameworks and contributes to feelings of efficacy, student identity, and motivation. The paper draws on current theory pertaining to online communities and examines this in relation to the extent to which the forum adds to feelings of academic and social integration. The study concludes that although the large forum environment facilitates a certain degree of academic integration and identity there is evidence that it also presents a number of barriers producing negative effects on student motivation and online identity.
A cultural-historical activity theory investigation of contradictions in open and distance higher education among alienated adult learners in Korea National Open University
Authors: Joo K. P.
Published: September 2016

Drawing upon cultural-historical activity theory, this research analyzed the structural contradictions existing in a variety of educational activities among a group of alienated adult students in Korea National Open University (KNOU). Despite KNOU’s quantitative development in student enrollment, the contradictions shed light on how the institution’s top-down, bureaucratic pedagogical system collided with individual expectations and needs. In particular, the participants’ critical viewpoints demonstrate the incompatible social roles that the open and distance higher education institution plays in Korean society. For example, while KNOU contributes to extending higher education opportunities for those who have unmet educational needs, the value of the KNOU degree has not been socially acknowledged since there is little, if any, competition in the entrance process. This study also documents how these contradictions were culturally and historically embedded in the participants’ distance higher education activities. Given the persistent contradictions, the research findings illuminate that KNOU’s efficiency-oriented model has not effectively facilitated the students’ learning as its distance higher education system is inevitably based on a compromise between a competitive, quality curriculum and the efficient extension of audiences.
Rethinking dropout in online higher education: The case of the Universitat Oberta de Catalunya
Authors: Grau-Valldosera Josep , Minguillón Julià
Published: September 2016

In recent years, several studies have been carried out into the reasons why students drop out of online higher education, following the rise in the relative weight of this form of education. However, more effort has gone into analyzing the causes of this phenomenon than into trying to characterize students who drop out, that is defining what a dropout student is. But obtaining a proper definition of dropout is just as important as describing its causes. It also appears that the definition of dropout is very sensitive to context. As one of the main findings of this article, we reach a pure empirical definition, at a programme level, of students who drop out of an online higher education context with non-mandatory enrollment. This definition is based on the probability of students not continuing a specific academic programme following several consecutive semesters of “theoretical break”, and is highly adaptable to institutions offering distance education with no permanence requirements, that is ones offering the possibility of taking breaks. Our findings show that there are differences regarding the number of consecutive semesters that define dropout depending on whether the programme requires previous experience or not. Additionally, we observe significant differences in the dropout rate between specific programmes, as well as a higher level of dropout in the first semesters. Analyzing the reasons behind these facts should help higher education institutions to make more sound and efficient decisions.
An exploratory study of effective online learning: Assessing satisfaction levels of graduate students of mathematics education associated with human and design factors of an online course
Authors: Lee Joohi
Published: September 2016

This exploratory research project investigated graduate students’ satisfaction levels with online learning associated with human (professor/instructor and instructional associate) and design factors (course structure and technical aspects) using a survey study. A total of 81 graduate students (master’s students who majored in math and science education) enrolled in an online math methods course (Conceptual Geometry) participated in this study. According to the results of this study, student satisfaction level is closely associated with clear guidelines on assignment, rubrics, and constructive feedback. In addition, student satisfaction level is related to professor’s (or course instructor’s) knowledge of materials.
How well do Canadian distance education students understand plagiarism?
Authors: Kier Cheryl Ann
Published: September 2016

This project ascertains how well students taking online, distance education courses at a Canadian university recognize plagiarised material and how well they paraphrase. It also assesses the types of errors made. Slightly more than half of 420 psychology students correctly selected plagiarised phrases from four multiple choice questions. Only a minority was able to rewrite a phrase properly in their own words. A more diverse sample of university students also had difficulty recognizing plagiarised passages from multiple choice options. The poor ability of students to identify plagiarised passages may suggest poor understanding of the concept. Students may benefit from training to improve their understanding of plagiarism.
An elaborated model of student support to allow for gender considerations in Asian distance education
Authors: Jung Insung , Hong Seongyoun
Published: September 2016

Research indicates that distance education (DE) students regard learner support systems as the key element in quality provision. This study sought to identify the key concerns of Asian DE students regarding support provision in different types of DE and dual-mode providers and formulate a student support model which took account of gender issues. An online survey was conducted with 1,113 distance learners in Japan, Korea, Hong Kong SAR China, Malaysia, India, Pakistan, Philippines, Singapore, and Thailand which required them to respond to open-ended questions regarding their main concerns over the quality of distance education. Their responses were analyzed with Nvivo 2.0 based on the framework of the Atkins (2008) ARCS model of distance learner support. It was found that in assessing the quality of DE the students valued 13 types of student support across five domains: affective, reflective, cognitive, systemic, and gender-considerate. It was also confirmed that there were gender differences in the students’ perceptions of the need for student support. Building on these findings, an elaborated model for student support for Asian distance learners was developed from a systems perspective, and from this, a list of supporting strategies was proposed.
