Construction, Identification, and Evaluation of Dengue Promotional Campaign Posters in a Language Classroom

Health promotional campaign as the practice of encouraging people to improve health has increased over the last decades in response to various health problems. This paper highlights strategies used by students to develop persuasive promotional campaign posters regarding the dengue health problem. Communication and media studies students were involved to show the combined results between the knowledge of health communication and the effective use of media in constructing an effective and persuasive health messages. A total of 56 students from two cohorts, i.e. twenty-five master’s students and thirty-one undergraduates were selected. Kurt Lewin’s model of action research was used to set the tasks: campaign objectives, information on dengue, themes/slogans to write the posters either by drawing or designing using a computer. The students were divided into groups where each group was monitored to record, check and evaluate their message writing performances. This study uses the Health Message Review Tool for data analysis which is grounded in the theories of Extended Parallel Process Model and Persuasion Hierarchy Effect. The findings revealed that the participants were able to construct, identify and evaluate major multi modal features in the dengue posters and persuasive elements which included: verbal texts, images, colours, graphic designs, metaphors, 1-sided and 2-sided message, firm conclusion and frames with more effective appeals. It was concluded that similar strategies may well be used in producing other campaign materials such as brochures, pamphlets, and billboards. The linguistic and pedagogic implications are also discussed at the end.

Factors, Affecting Students’ Decision to Enroll in a University

Globally, Higher Education Providers are seeking new ways of increasing student recruitment and diversify economic growth. The market in Dubai for higher education is very competitive originating “excess educational supply. ” In the case of Dubai, the factors which students consider may vary due to a diverse background of the students and a wide selection of study options. Analyzing and forecasting student choice factors enables a university to take the right strategy, position on the market. Therefore, a university should be able to distinguish itself by focusing on factors which students consider locally, instead of known common aspects which over universities overseas consider for their students. Two surveys were conducted highlighting the decision factors. Secondary research created the foundation for the primary research targeting Dubai-based students. In total, 75 current and 220 potential students participated in the survey, where demographics, factors, and preference of university location were examined. To analyze the data, the mean analysis and MANOVA were used. Also, an integrated marketing communication (IMC) analysis of the brand was conducted. The researchers observed a significant difference between Dubai and the global market. Results reveal that majority of the students consider degree recognition as the most important aspect of their education, followed by career after graduation, academic excellence, and practical approach. There was no direct correlation between the location and a final decision to join. The list of recommendations was created to enhance the IMC practices in the niche market, including conventional and digital marketing, events and PR. One of the limiting factors of this research can be considered the diverse sample of respondents (nationality, curriculum, residency location). This research serves as a foundation for marketing campaigns for Dubai universities and can contribute to the strategic roadmap by focusing on prime factors affecting students’ decision.
Impact of excess cash on earnings management and firm value: Evidence from China

This study examines how excess cash drives earnings management and firm value in China. Using a fixed effect panel regression on a sample of 12,629 observations covering 300 firms listed in the Shanghai Stock Exchange, we find that excess cash has a positive impact on firm value confirming pecking order theory. Our results show that earnings management has a negative impact on firm value in China, which supports the efficient earnings management view. We find that managers in Chinese firms are less likely to use excess cash for manipulating earnings. We provide empirical evidence that firms with excess cash seem to use it more for precautionary purpose than earnings management and the excess corporate liquidity of Chinese firms is used for value-enhancing activities. The test of robustness using the Instrumental Variable (IV) model confirms the results of the study. Our study merges two areas of corporate finance by incorporating agency problems concerning earnings management and cash holdings
Capturing and maintaining value by innovation intermediary organisations

In 2005 I finished the MSc in Land and Water management at Van Hall-Larenstein. Managing water systems has interested me throughout my life. As a young boy I went fishing for weeks on end. And when I was at home I watched either David Attenborough or Jacques Cousteau. When in high school, I was digging fish ponds in peoples gardens. And when moving into college and university, I learned all there is to learn about ecology in relation to landscape and water management. Dul & Hak (2008) emphasize that the ‘exploration and defining the research topic’ is a very important phase. I had ideas, but while choosing a thesis-topic found it very difficult to apply this prescription. I am self-employed, so I can choose whatever I like. I experienced this to be an enormous privilege. It also made choosing challenging, because of the many interesting topics throughout the last semesters at the RSM and during my fifteen years of working that preceded it. ‘Going back to where I was coming from’, turned out to be the solution. I was going to study the concept of Building With Nature. In September 2017 I started the part time master of science program in Business Administration (MScBA). The first three semesters have been intense, but I would not have wanted to miss them for the world. It has been a true enrichment of my life. This document contains the final assignment in this life changing program, the master thesis. Thinking back, finding a fitting research topic has been a search on itself for me, a soul-search. I am nevertheless pleased with the topic this journey turned out guiding me towards. In this regard, I was very much charmed and surprised by the somewhat disillusioning closing line of Evanschitzky et al;“of course, that is why science calls it research and not just search” (2012, p.30). That, is the very essence of me signing up for the program. I say a word of thanks to my coach, Dr. Wim Hulsink and co-reader, Dr. Koen Dittrich for their expertise and the important feedback they have given me along the way. I also thank my interviewees located in various different organizations. I chose to interview a variety of people, the fact that they were all willingly cooperating, providing me with valuable and practical information, enabled me to make this research project a success. I want to explicitly thank my parents Willem and Willemien Morijn, who are always unconditionally supportive and interested in my endeavours and progress in life. Furthermore, I thank my brother John Morijn, who is a very sharp thinker, very critical in his opinions and who has given me many examples of how to accomplish what you wish for in live. It comes down to having guts, being perseverant and don’t being bothered about what other people think of you too much. Finally, I address Martijn Kampshoff and Dianne van Essen. As both my business partners and friends, they have facilitated me in remarkable ways.

*These authors contributed equally to this work Purpose: The objective of this research was to validate the diagnostic value of threedimensional texture parameters and clinical characteristics in the differentiation of colorectal signet-ring cell carcinoma (SRCC) and adenocarcinoma (AC). Methods: We retrospectively analyzed data from 102 patients with SRCC or AC confirmed by pathology, including 51 SRCC (from January 2015 to July 2019) and 51 AC patients (from January 2019 to July 2019). CT findings and clinical data, including age, gender, clinical symptoms, serological biomarkers, tumor size, and tumor location, were compared between SRCC and AC. CT texture features were quantified on portal phase images using three-dimensional analysis. A list of texture parameters was generated with MaZda software for the classification of tumors. The texture features, clinical data and CT findings were statistically analyzed for the discrimination ability of SRCC and AC, and the potential predictive parameters that may be used to differentiate the two groups were subsequently tested using the least absolute shrinkage and selection operator (LASSO) and logistic regression analyses. The receiver operating characteristic curve (ROC) provided a range of values for establishing the cutoff value, as well as the sensitivity and specificity of prediction for each significant variable. Results: SRCC occurred more often in men than AC did (80.39% vs 49.02%, P < 0.01). The patients were younger in the SRCC group than in the AC group, without a statistically significant difference (55.84 vs 59.20 years, P = 0.216). There were no significant differences in the clinical symptoms, tumor size, or tumor location between the two groups (P=0.505, P=0.19, P=0.843, respectively). The elevation of serological biomarker CA724 was more common in SRCC than in AC (P< 0.001). Perc.01%3D, Perc.10%3D and s(1,0,0) SumAverg were lower in the SRCC group than in the AC group during the portal phase, with the areas under curve (AUCs) of 0.892–0.929, sensitivity of 76.5–84.3% and specificity of 88.2–96.1%. In the differentiation between SRCC and AC, the 1-NN minimal classification error (MCR) was 29.41%. Conclusion: Three-dimensional texture parameters, including Perc.01%3D, Perc.10%3D and s(1,0,0) SumAverg, exhibited a favorable discriminatory ability to distinguish SRCC from AC.
Synthetic lethal interactions between ATR and DNA polymerases as a novel concept for individualized cancer therapy

57 In the previous study of our laboratory,we demonstrated that not only genetically inducedATR deficiency but also chemical inhibition of the ATR pathway inhibits proliferation upon POLD1 depletion. To extend these data,we now characterized the impact of defined POLD1 variants on the sensitivity to ATR pathway inhibitors. Therefore, we used the CRISPR/Cas9 technique in the colorectal cancer cell line DLD-1, which harbors four heterozygous POLD1 variants, to establish heterozygous POLD1-knockout cloneswith exclusive expression of distinct POLD1 variants. These knockout clones served as amodel to determine the functional significance of individual POLD1 variants. We demonstrated that of the four variants analyzed onlyPOLD1R689W impairs POLD1 function, as shownbycompensatoryATRpathway activation and impaired DNA replication. Moreover, the POLD1R689W variant in cancer cells led to a strong decrease of cell survival in vitro and decelerated growth of murine xenograft tumors in vivo upon treatmentwithATRpathwayinhibitors,which further corroborates a potential clinical relevance of our data. Our here established and characterized functional model could thus be used to complement algorithmbasedmodels to predict the pathogenicity of tumor-specific variants of uncertain significance, and improve their accuracy. Furthermore, our data enable a novel and potentially clinically relevant concept for the individualized and genotype-based therapy of POLD1-deficient cancerswith ATR pathway inhibitors. Taken togetherwith the in the literature identified variants of uncertain significance of POLD1 and POLE aswell as defects in other polymerases in cancer the data of this dissertation illustrate the emerging role of tumor-specific alterations inDNA polymerases as novel therapeutic targets. The comprehensive identification and functional characterization of all polymerases and their possible synthetic lethal partners is thus essential in future studies.
Towards accessible content creation of real world objects for virtual environments

3D reconstruction is the general problem of creating 3D models from real world objects. In today's movie and games industry, there is an increasing demand for using real world content as assets in production. In general, however, 3D reconstruction is a challenging problem, and current techniques only allow for production-ready results given a combination of expensive equipment and specific expertise. This thesis is a collection of three papers that address various aspects of this general problem of 3D reconstruction, with the aim of lowering the bar for making usable real world content. In Paper I, we address the problem of storing and streaming time varying geometry for e.g.\ free-viewpoint video, which otherwise has too high bandwidth requirements to be streamed efficiently. We use a memory-efficient structure based on compressed voxels to store the data, in which we can send only incremental updates to the geometry in each frame. In Paper II, we implement an end-to-end real-time pipeline for free-viewpoint video communication. The pipeline uses a set of ordinary webcams as input and do all processing on a single desktop computer. Even with these limitations, we show that we can produce free-viewpoint video with agreeable quality in real-time. Paper III addresses the problem of accessible and accurate modeling of static real-world objects. Given a set of calibrated input images, we have developed an interactive tool that makes 3D reconstruction with multi-view stereo more accessible. This interactive reconstruction has several advantages over automatic 3D scanning, since we obtain correct topology by design as well as information about visibility and foreground segmentation.
Opportunity Costs during PhD Enrolment: An Innovative Information Systems Research Training Programme

Expectations of completing PhDs for job readiness are increasing. Information Systems (IS) PhDs face the additional challenge of appreciating the multidisciplinary and multi-paradigmatic diversity of the discipline, demanding a breadth of knowledge beyond that expected in many other disciplines. Further, PhD students in Australian universities are constrained to a 3+ year enrolment, as compared for example, to the more common 4 and 5 year enrolments in North American universities. These demands require that IS PhD students in Australia be discriminating in their choice of activities during enrolment. With the aim of maximizing the value of the PhD experience, this study explores synergy between research and teaching. More specifically, this research-in-progress (RIP) paper reports a programme design for training PhD students, through involvement as supervisors of coursework Masters students’ research projects.
A Study on Energy Harvesting Wireless Sensor Networks

Wireless sensor networks offer an attractive solution to several environments, security, and process monitoring problems. However, one barrier for their full adoption is the need to provide electrical power over extended periods of time without the need of dedicated wiring. Energy harvesting offers good solutions to this problem in several applications. This paper surveys the energy requirements of typical sensor network nodes and summarizes the future research work in the field of energy harvesting resource allocation in wireless sensor networks
The use of Visual Recurrence Analysis and Hurst exponents as qualitative tools for analysing financial time series

Complex dynamical systems existing in an unobservable multidimensional space can be successfully represented via an artificial vector space, created from the single output variable of such a dynamical system. Visual Recurrence Analysis (VRA) method enables visualisation of the single time series in such a space. This paper uses VRA method and Hurst exponents as the means of estimating, describing and qualifying some of the properties of several financial time series. Weak evidence of chaos in daily returns is indicated.
The Impact of Initial Grades on Students’ Further Academic Achievement

I study the effect of grading on students’ further academic achievement. I introduce an anonymous university data set and use it do discover grading patterns, in particular to find out whether higher grades can lead to better academic outcomes later on. I build a model that illustrates how effort-augmenting grading generosity can improve student effort through higher reference points and higher returns to effort. JEL Codes: C81, I20, I21, I23.
Graphene field-effect transistors and devices for advanced high-frequency applications

New device technologies and materials are continuously investigated, in order to increase the bandwidth of high-speed electronics, thereby extending data rate and range of applications. The 2D-material graphene, with its intrinsically extremely high charge carrier velocity, is considered as a promising new channel material for advanced high frequency field-effect transistors. However, most fabrication processes introduce impurities and defects at the interface between graphene and adjacent materials, which degrade the device performance. In addition, at high drain fields, required for high transistor gain, the close proximity of the adjacent materials limits the saturation velocity, and there is a significant increase in the channel temperature caused by self-heating. In this thesis, the influence of impurities and defects on charge transport, the limitations of the saturation velocity, and the effect of velocity saturation and self-heating on the transit frequency (fT) and the maximum frequency of oscillation (fmax) of graphene field effect transistor (GFETs) are analysed. In addition, GFETs with state-of-the-art extrinsic fT =34 GHz and fmax =37 GHz, and an integrated 200-GHz GFET based receiver are presented. Also, through the development of a fabrication process of GFETs with a buried gate configuration, this work contributed to the direct nanoscopic observation of plasma waves in the GFET channel during terahertz illumination. The study was conducted by (i) setting up a model describing the influence of impurities and defects on capacitance and transfer characteristics at low electric fields, (ii) by developing a method for studying the limiting mechanisms of the charge carrier velocity in the graphene channel at high electric fields and answering the question whether velocity saturation improves fmax, (iii) by developing a method to study the channel temperature and its effect on fT and fmax. It was found that scattering by remote optical phonons limits the saturation velocity and charge carriers emitted from interface states at high fields are preventing the current to saturate and, hence, limiting fT and fmax. Additionally, the study shows that the channel temperature in GFETs can increase significantly causing degradation of the high frequency performance due to the decrease of charge carrier mobility and velocity. In summary, this work shows that it is necessary to develop a GFET design and fabrication process providing clean and defect-free interfaces, to minimise parasitic effects, and to use materials with higher optical phonon energies and higher thermal conductivities than those used today. This will allow for realisation of GFETs with extrinsic fT and fmax in the sub-terahertz range.
The quantum correlation between the selection of the problem and that of the solution sheds light on the mechanism of the quantum speed up

In classical problem solving, there is of course correlation between the selection of the problem on the part of Bob (the problem setter) and that of the solution on the part of Alice (the problem solver). In quantum problem solving, this correlation becomes quantum. This means that Alice contributes to selecting 50% of the information that specifies the problem. As the solution is a function of the problem, this gives to Alice advanced knowledge of 50% of the information that specifies the solution. Both the quadratic and exponential speed ups are explained by the fact that quantum algorithms start from this advanced knowledge. 1 Outline of the argument Quantum algorithms require fewer computation steps than their classical counterparts. The reason for this quantum speed up is not well understood. For example, recently Gross et al. [1] asserted that the exact reason for it has never been pinpointed. The key to the present explanation of the speed up is the quantum correlation existing between the selection of the problem on the part of Bob (the problem setter) and that of the solution on the part of Alice (the problem solver). Because of it, all is like Alice contributed to selecting 50% of the information that specifies the problem. Since the solution is a function of the problem, this gives to Alice the advanced knowledge of 50% of the information that specifies the solution. The speed up is explained by the fact that Alice starts from this advanced knowledge. The quantum correlation we are dealing with appears at the level of the whole quantum experiment, from the measurement required to put the quantum system in a known state, necessary to prepare the problem, to the measurement required to extract the solution – see also [2, 3, 4]. We focus on Grover’s [5] quantum search algorithm. Bob selects a value of b ∈ {0, 1}, Alice should find it by computing the Kronecker function δ (b, a)
Using Duolingo as a means of enhancing (Post) Obligatory Secondary Education Students’ interest in the English subject

This research has aimed at studying and analysing the effects of using Duolingo, a mobile phone application, on the youngest and the oldest students of a Spanish high school. Basing the research on the premise that the so called digital natives students would feel much more comfortable and motivated by using a technological device for learning, I have endeavoured to prove that young learners of English would be more eager to learn the language if they are given the chance to use a tool such as Duolingo, since it is a mobile phone application and these students use this type of tools as part of their daily life. After having the students use Duolingo for a couple of weeks at home, they were asked about their experience and it was shown that, unexpectedly, the older students had actually enjoyed Duolingo as much as the younger ones, although the application proved to be more useful for the students of the first year of Compulsory Secondary Education, since the level that Duolingo offered was not sufficient for students of Post Obligatory Secondary Education. However, both groups showed interest in incorporating Duolingo as part of their English learning process.
