Measuring User Experience During a Web-based Survey: A Case of Back-to-Back Online Surveys

The vast availability of the Internet allows surveyors to conduct web-based survey much easier than its offline counterpart. Previous studies have been conducted to measure survey tool usability. This article reports the results of a survey on the experience of students who have just completed a survey on students’ learning engagement. Students were emailed to participate on a survey about students' engagement on the learning process. After they have completed the survey, they were asked to complete another survey, a shorter one, to measure their experience during their first assignment. The second survey employed the user experience questionnaire (UEQ). The UEQ comprises 26 questions to measure six variables. There were 819 respondents who completed the first survey that 450 of them were voluntarily completed the second one. Data were analysed using UEQ data analysis. The result showed that out of 26 items, eight of them were evaluated positively and the rest were evaluated neutrally. Amongst those that were evaluated positively include friendly, good design, supportive, secure, organized, understandable, clear, and valuable .
Exploring the interaction between Financial Performance and Corporate Social Responsibility in Pakistani Firms

The concept of Corporate Social Responsibility (CSR) is as old as the business organizations. Business is considered to be one of the most important agents of changes within society for the last two centuries. CSR is a source of realizing the organizations about their obligations and responsibilities towards the society where they perform their business activities. However, in order to perform CSR activities Financial Performance (FP) plays a critical role. As firms with better financial performance are in the better condition to provide the necessary funds and make investments for their social domains. In return these social activities not only help the firms in improving their profitability but also enhance their social value and reputation in the market as well. Therefore, both CSR and FP are interlinked with each other. Present study focused to find out the type of interaction that exists between CSR and FP in case of Pakistan. A panel data set of 100 non-financial firms for the period of 2006-2009 has been collected. Hausman test is applied on panel data in order to identify the fixed and random effect. Results of Generalized Least Square Random Effect Regression revealed the positive interaction between CSR and FP.
The Effect of Problem Based Learning (PBL) Model and Jigsaw Type of Cooperative Learning Model with Prezi Aid on the Students' Learning Outcome

PBL model and jigsaw type of cooperative learning model with prezi aid are two learning models that can increase the students’ ability in solving problem, improving students’ activeness, improving the students’ ability in technology use and improving the learning outcome. This research aims to find out the difference of economic learning outcome between problem based learning model with prezi aid and jigsaw type of cooperative learning with prezi aid. This study was a quantitative research with experimental method. The population of research used in this research was all students of Public Senior High Schools in Surakarta. The sampling technique used was random sampling. The sample of research consisted of 66 students: 32 10th IIS4 graders of SMA 5 Surakarta as experiment class using problem based learning (PBL) model with Prezi media aid, and 34 10th IIS-2 graders of SMA Negeri 7 Surakarta as control class using Jigsaw type of cooperative learning model with Prezi media aid. The result of research showed that there was a significant difference of learning outcomes between the students using problem based learning (PBL) model with Prezi media aid and those using Jigsaw type of cooperative learning model with Prezi media aid. It could be seen from the significance value (Sig) lower than significance level = 0.05 (0.038 < 0.05) or (Fobs = 4.477 > Ftable = 3.98).

The Effects of Maltodextrin and Gum Arabic on Encapsulation of Onion Skin Phenolic Compounds

In this study, the effect of coating material and core to coating ratio on the encapsulation of phenolic compounds extracted from the onion skin was investigated. As coating material maltodextrin and gum arabic at different ratios were chosen (10:0, 6:4 and 8:2). The core to coating ratios were 1:10 and 1:20. The microcapsules were prepared with high speed homogenizer at 10000 rpm for 10 min. The freeze dried microcapsules were analysed in terms of encapsulation efficiency, antioxidant activity and particle size distribution. The encapsulation efficiencies were mostly lower when core to coating ratio was 1:10 as compared to the core to coating ratio of 1:20. There was positive correlation between total phenolic content and antioxidant activity. The ratio of maltodextrin and gum arabic had significant effect on encapsulation efficiency, however antioxidant activity values did not change significantly with different ratios. As core to coating ratio increased, the size of microcapsules were found to be larger. Maltodextrin and gum arabic ratio had also significant effect on particle size distribution.
Bosonisation of the one-dimensional two-fermion model: boson representation

Jordan's theory of the boson representation of the fermion fields in one dimension is reviewed and generalised to the one-dimensional two-fermion model (TFM). It is shown that an additional constraint (Jordan's commutator) on the fermion fields has been overlooked so far by the theory of the TFM. This supplementary condition requires a particular cut-off procedure which has been little considered in recent times.
Cloud and the corresponding precipitation chemistry in south China: Water‐soluble components and pollution transport

[1] To investigate the transport and deposition of pollutants in south China, the chemical composition of cloud water and rainwater was studied at Mount Heng, which is located in the heart of China's acid rain affected region. A total of 194 cloud samples and 38 event-based precipitation samples from March to May 2009 were analyzed for a wide variety of water-soluble compounds. The volume-weighted mean (VWM) pH of cloud water was 3.80, indicating an acidic nature. Compared with cloud water, precipitation was much less acidic with a VWM pH value of 4.35. The concentration results show that in cloud water, SO42− was the dominant anion, followed by NO3−, controlling the acidity, while NH4+ accounted for 69.8% of the total cations, dominating the cloud water neutralization. In rainwater, a similar situation appeared, but with a slightly higher Ca2+concentration. In both cloud water and precipitation the acidities were found to be mainly due to sulfuric acid, followed by nitric acid. The calculation of neutralization factors and the application of multiple linear regression analysis showed the higher NH4+ contribution to the neutralization process in both types of samples. The very weak correlations of ions in rain with the ones in cloud water on the event basis suggested that cloud and precipitation events may be associated with different air masses. With relatively high ionic concentrations and higher frequency, air masses from the east and south directions were associated with the high cloud deposition of the major species at our site.
Relatior^ships Between Adult Workers' Spiritual Well-Being and Job Satisfaotion: A Preliminary Study

The authors studied the relationships between aduit v\/orl<ers' spiritual weiibeing and job satisfaction, Two hundred participants compieted 2 instruments: the Spirituai Weii-Being Scale (C, W. Eiiison & R. F, Paloutzian, 1982) and the Minnesota Satisfaction Questionnaire Short Form (D, J.Weiss, R. V. Dawis, G. W. Engiand. & L. H. Lofquist. 1967). A bivariate correlational analysis showed spirituai well-being, religious weii-being, and existentiai weii-being to be positiveiy reiated to job satistaction for this sample. With a forced-entry multipie regression analysis, overaii spirituai weii-being was found to have a moderate infiuence, existentiai weii-being had a much stranger infiuence, and reiigiaus weii-being had a minimai intiuence aii on, general job satisfaction.
A meta-analysis of particle water uptake reconciliation studies

Abstract. Water uptake by aerosol particles controls their ability to form cloud droplets, and reconciliation between different techniques for examining cloud condensation nuclei (CCN) properties is important to our understanding of these processes and our ability to measure and predict them. Reconciliation between measurements of sub-saturated and supersaturated aerosol particle water uptake was attempted at a wide range of locations between 2007 and 2013. The agreement in derived number of CCN (NCCN or particle hygroscopicity was mixed across the projects, with some data sets showing poor agreement across all supersaturations and others agreeing within errors for at least some of the supersaturation range. The degree of reconciliation did not seem to depend on the environment in which the measurements were taken. The discrepancies can only be attributable to differences in the chemical behaviour of aerosols and gases in each instrument, leading to under- or overestimated growth factors and/or CCN counts, though poorer reconciliation at lower supersaturations can be attributed to uncertainties in the size distribution at the threshold diameter found at these supersaturations. From a single instrument, the variability in NCCN calculated using particle hygroscopicity or size distribution averaged across a project demonstrates a greater sensitivity to variation in the size distribution than chemical composition in most of the experiments. However, the discrepancies between instruments indicate a strong requirement for reliable quantification of CCN in line with an improved understanding of the physical processes involved in their measurement. Without understanding the reason for discrepancies in the measurements, it is questionable whether quantification of CCN behaviour is meaningful.
Determinants of Brand Loyalty: A Study of the Experience-Commitment-Loyalty Constructs

Marketing strategies for brands have shifted its focus on relationships and value creation that directly links to brand loyalty, is the main focus of this paper and two key factors: brand experience and brand commitment, within automotive sector, are investigated to examine relative relationships. These factors have already been established to have a connection to brand loyalty. However, as brand commitment consists of both affective and continuance commitment, it is still somewhat unclear about which of these aspects of commitment has the greatest, or most important impact on brand loyalty. Moreover, the existing research and literature surrounding the brand experience construct is extensive. However, it is not entirely clear regarding this constructi¯s relationship to brand loyalty. While some authors claim that it affects brand loyalty directly, others have found that it is a dependent variable, which, alone does not have any immediate effect on brand loyalty. This study also investigates a connection between brand experience and brand loyalty as far as automotive sector is concerned, both with and without commitment as a mediator. As a result, continuance commitment was found to not have any considerable impact on the consumeri¯s loyalty towards a brand, it is assumed that factors such as price and other available alternatives dos not influence this desire to maintain said relationship.
Minimal residual disease monitoring in neuroblastoma

Neuroblastoma is the third most common childhood cancer. The presence of metastatic spread at diagnosis is the most important factor in determining outcome in patients with neuroblastoma. Despite intensive treatment, relapse frequently occurs and only approximately 40% of patients remain long term disease-free. Residual neuroblastoma cells are thought to be the major cause of relapse and bone marrow is a frequent site of recurrent disease. Minimal residual disease (MRD) is the term used to describe small numbers of tumor cells remaining in blood or bone marrow during or after treatment, which are below the limits of detection using morphological assessment. Real-time quantitative PCR (RQ-PCR) is a highly sensitive technique to detect MRD. Clinical data on MRD detection in neuroblastoma are promising and large prospective studies are ongoing or results have been published. The studies presented in the first part of the thesis focused on identifying new MRD markers to improve MRD detection. We describe that patient-specific DNA markers are reliable and stable disease markers, that circulating tumor DNA can be of additive value in disease monitoring and we identified markers specific for the detection of mesenchymal type neuroblastoma cells. In the second part of the thesis the clinical significance of MRD detection was studied. Detection of high levels of neuroblastoma mRNA in patients with localized disease was associated with an unfavorable outcome, therefore for these patients a more careful follow-up is advisable. MRD detection in high risk neuroblastoma is currently being studied in a large international prospective study. An interim analysis of this study revealed that high levels of neuroblastoma mRNA in bone marrow at diagnosis was associated with a poor outcome. Bone marrow response after completion of induction chemotherapy was not associated with a better outcome. However, more patients need to be included and the follow-up time should be increased.
Woodpeckers abundance in the Białowieża Forest - a comparison between deciduous, strictly protected and managed stands

In 2007-2009 we counted all woodpeckers along seven transects (4.6-8.0 km long) in de- ciduous stands of the Bialowieza Forest, NE Poland. Three transects ran along stands of the strictly protected part of the Bialowieza National Park (BNP) and four in managed stands of the forest. The total number of recorded woodpeckers per 1 km of transect (hereafter treated as an index of abun- dance) was on average 9.0 (SE=0.4) in BNP and 5.4 (SE=0.4) in managed stands. The most common species was Great Spotted Woodpecker Dendrocopos major, while the least numerous were Wryneck Jynx torquilla, Grey-headed Woodpecker Picus canus in all transects, and Three-toed Woodpecker Picoides tridactylus in managed stands. In comparison with 1999-2001, indices of abundance of all woodpeckers increased in 2007-2009 by 1.4/km in BNP and by 0.8/km in man- aged stands due to increasing index of D. major. We found that woodpeckers' situation in managed stands is getting worse compared to BNP. This study confirms the importance of ecological reference of the Bialowieza National Park, especially for White-backed Woodpecker D. leucotos and Three-toed Woodpecker.
Application of support vector regression to predict metallogenic favourability degree

Mineral resource prediction is becoming increasingly important as researchers attempt to resolve the prospect direction by mining geological data. In this paper, Support Vector Regression (SVR) is applied to predict iron deposit metallogenic favourability degree since SVR is a powerful tool to solve the problem characterized by smaller sample, nonlinearity, and high dimension with a good generalization performance based on structural risk minimization. The paper discusses the support vector regression algorithm in some detail, describes a SVR based-system that learns from examples to predict metallogenic favourability degree of iron deposit and contrasts this approach with Partial Least Squares (PLS). The experimental results show that SVR has high recognition rates and good generalization performance for small sample, especially good for treating the data of some nonlinearity in geology.
Car Driving Behaviour on Road Curves: A Study Case in Universiti Tun Hussein Onn Malaysia

The World Health Organization (WHO) predicted that in 2020, road accidents will become the third cause of deaths in the world. Several factors contribute to road accidents, among them are human error, speeding, irregularities in road design and period of driving (either nighttime or daytime). In road design, horizontal curves are of particular interest to the designer, given that accidents are very likely to occur at such locations if drivers lose control of their vehicles due to inappropriate speed choices. This study was conducted to investigate the variation of driving behaviour on horizontal curves. The test car was fitted with a Global Positioning System (GPS) device and driven by 30 participants. The research findings show that drivers’ choice of speed varies while approaching horizontal curve, on the curve and just after leaving the curve. Apart from this, although drivers were found to have driven at a slightly higher speed during daytime compare to evening driving, however the difference was not significant. A comparison between genders also revealed that female and male drivers drive at similar speed behaviour
The effect of tillage practices on a leek crop’s nitrogen utilisation from a grass-clover sward

A grass-clover ley may serve to build soil fertility. However, destruction of the sward may result in a high mineral N content in the soil profile in autumn. We have therefore investigated if non-inversion tillage is feasible for destruction of a grass-clover sward. We also examined how mode and timing of destruction would affect the N availability as reflected by total N uptake of the subsequent main crop leek (Allium porrum) and the residual mineral N. Early destruction in March appeared to be the least favorable option due to the highest residual mineral N content at values of total plant biomass and N uptake not higher than those obtained after late destruction of a repetitively mulched grass-clover sward. Non-inversion tillage proved to be successful for destruction of a grass-clover sward. It did not lower total plant biomass and N uptake by leek when compared to mouldboard ploughing. Grass-clover management history and time of destruction were decisive for the N availability.
UvA-DARE ( Digital Academic Repository ) A rewarding view on the mouse visual cortex : Effects of associative learning and cortical state on early visual processing in the brain

Anesthesia affects brain activity at the molecular, neuronal and network level, but it is not well-understood how tuning properties of sensory neurons and network connectivity change under its influence. Using in vivo two-photon calcium imaging we matched neuron identity across episodes of wakefulness and anesthesia in the same mouse and recorded spontaneous and visually evoked activity patterns of neuronal ensembles in these two states. Correlations in spontaneous patterns of calcium activity between pairs of neurons were increased under anesthesia. While orientation selectivity remained unaffected by anesthesia, this treatment reduced direction selectivity, which was attributable to an increased response to the null-direction. As compared to anesthesia, populations of V1 neurons coded more mutual information on opposite stimulus directions during wakefulness, whereas information on stimulus orientation differences was lower. Increases in correlations of calcium activity during visual stimulation were correlated with poorer population coding, which raised the hypothesis that the anesthesia-induced increase in correlations may be causal to degrading directional coding. Visual stimulation under anesthesia, however, decorrelated ongoing activity patterns to a level comparable to wakefulness. Because visual stimulation thus appears to ‘break’ the strength of pairwise correlations normally found in spontaneous activity under anesthesia, the changes in correlational structure cannot explain the awake-anesthesia difference in direction coding. The population-wide decrease in coding for stimulus direction thus occurs independently of anesthesia-induced increments in correlations of spontaneous activity.
DYNAMICS OF GROWTH, POVERTY AND HUMAN CAPITAL: EVIDENCE FROM INDONESIAN SUB-NATIONAL DATA

The aim of this study is twofold. First, despite the vast empirical literature on testing the neoclassical model of economic growth using cross-country data, very few studies exist at the sub-national level. We attempt to fill this gap by utilizing panel data over the 2002-2012 period, a modified neoclassical growth equation, and a dynamic panel estimator to investigate the effect of both health and education capital on economic growth and poverty at the district level in Indonesia. Secondly, whilst most existing cross-country studies tend to concentrate only on education as a measure of human capital, we expand the analysis and probe the effects of health capital as well. As far as we are aware, no study has done a direct and comprehensive examination of the impacts of health on growth and poverty at the sub-national level. Thus this study is a premier at the sub-national level, and our findings will be particularly relevant in understanding the role of both health and education capital in accelerating growth and poverty reduction efforts.
Clarifying the Effects of R&D on Performance: Evidence from the High Technology Industries

It has been assumed that there is a clear linear causal effect of research and development (R&D) on performance. However, recent empirical studies have shown both a positive relationship, which suggests an increase in R&D leading to improved performance, as well as a negative relationship, which suggests an increase in R&D resulting in poor performance. Therefore, the evidence for this assumption is not as clear-cut as might be expected, despite a number of efforts to validate it. This paper proposes a new unified nonlinear relationship that incorporates both effects (optimal and threshold) into the proposed model. In examining a panel data of high-technology industry, the relationship between R&D and performance could be graphically depicted as an inverse S-shaped nonlinearity. Our empirical findings also confirmed not only an optimal effect that a specific level of R&D corresponded to maximum performance, but also a threshold indicating that a minimum level of R&D is required in order for R&D to be effective.
