Listening to Teachers’ Needs: Human-centred Design for Mobile Technology in Higher Education

Technology is developing fast. Especially mobile and wearable technology is on the rise. Educational technology has seen considerable developments in different technological areas recently. However, the vast development of everyday technology is not reflected in educational settings and the fast adaption of innovative technology is missing in the educational sector. This thesis applies a Human-centred Design (HCD) process to analyze the context of teaching in higher education, to understand teachers’ needs and requirements to design innovative and up-to-date technology. It was found that teachers lack motivation to integrate technology into their teaching processes. Learning tasks were found to be a critical component in teaching and learning processes. Therefore, the support of teaching processes around learning tasks was chosen as the central problem in this thesis. The use case of alpine sport teaching was chosen for an in depth analysis of learning tasks. To address the motivational problem, gamification was taken into consideration. Games are known for their motivational factors and effects. Due to the similarities between learning tasks and game tasks, an extensive analysis on how to design for motivating tasks based on lessons learned from game tasks was conducted. The findings include that certain game elements, structures and processes can be used to design for motivating learning tasks. From the context of use analysis in teaching and the findings from the game analyses, the Dynamic Questing (DynQ) concept was developed. The DynQ concept consists of learning task creation, task triggering, context sensing and feedback generation. A proof-of-concept prototype was developed to test out the DynQ concept and to be used for user testing with alpine sports teachers. After that, the concept was also tested with teachers from different teaching contexts. Further design and development of the system could help improve usability and user experience. This work forms a basis for the advancement of personalized and contextualized learning through mobile and wearable technology support.
BUYER-SUPPLIER RELATIONSHIPS IN ACCOUNTING SOFTWARE INDUSTRY: THE EFFECTS OF TRUST AND SWITCHING COST

T he purpose of this work is to investigate the effects of relationship antecedents; perceived ease of use (PEOU), perceived usefulness (PU) and service quality, on technology adoption in the accounting software industry via trust and switching cost. The paper uses a causal modeling approach and proposes a conceptual model after an extensive review of literature. A large quantitative survey was conducted with 709 professional accountants in Turkey, who are accounting software program users and the model was tested using structural equation modeling. We found that service quality, PEOU and PU had positive effects on trust, whereas only perceived usefulness was positively correlated with switching cost. Trust showed positive influence on switching cost. Trust was found positively correlated with long-term affective commitment, whereas switching cost had positive and significant effect on calculative commitment in the short-term. The paper discusses different criteria that lead to accounting software usage and works as a strategic guideline for software firms in order to keep professional accountants in the relationship.
Complementary functions of E1a conserved region 1 cooperate with conserved region 3 to activate adenovirus serotype 5 early promoters

The amino-terminal region of the adenovirus type 5 E1a protein including conserved regions (CRs) 1 and 2 binds the 105-kDa retinoblastoma protein and a second, 300-kDa, cellular protein. We show that mutant viruses with deletions of CR1 which release the binding of either p105 or p300 still activate early promoters and infect cells productively. However, mutations which disrupt binding of both proteins disrupt early promoter activity and block the viral life cycle. Ela CR3, which has an established role in early promoter activation, can act in trans to the amino-terminal functions. This suggests that the amino terminus provides distinct, redundant functions related to p300 and Rb binding that synergize with CR3 to transactivate early genes.
Robustesse et Identification des Applications Communicantes

La popularite des reseaux informatiques et d'Internet s'accompagne d'un essor des applications communicantes et de la multiplication des protocoles dont le fonctionnement est plus ou moins complique, ce qui implique egalement des performances differentes en termes de robustesse. Un premier objectif de cette these est d'approfondir plus en details la robustesse de protocoles s'illustrant par d'extraordinaires performances empiriques tels que les botnets. Differents protocoles employes par les botnets sont donc modelises dans cette these. Par ailleurs, l'essor et la diversite des protocoles s'accompagnent d'un manque de specification volontaire ou non que la retro-ingenierie tente de retrouver. Une premiere phase essentielle est notamment de decouvrir les types de messages. La technique mise en \oe uvre dans cette etude s'appuie sur les machines a vecteurs de supports tout en ayant au prealable specifie de nouvelles representations des messages dont la complexite de calcul est tres reduite par rapport aux autres techniques existantes. Enfin, il existe generalement un grand nombre d'applications distinctes pour un meme protocole et identifier precisement le logiciel ou le type d'equipement utilise (marque, version) est un atout essentiel dans plusieurs domaines tels que la supervision ou la securite des reseaux. S'appuyant uniquement sur les types de messages, le comportement d'un equipement, c'est-a-dire la maniere dont il interagit avec les autres, est une information tres avantageuse lorsqu'elle est couplee avec les delais entre les messages. Enfin, la grammaire d'un protocole connu permet de construire les arbres syntaxiques des messages, dont le contenu et la structure semantiquement riche, avaient peu ete etudies jusqu'a maintenant dans le cadre de l'identification des equipements.
Direct adaptive control for position drive of the prototype's axis of telescope's rotational support device with elastic deformations

To the optical mechanical complexes of tracking and positioning, strict requirements are produced on the dynamics and permissible errors under such conditions as external and internal nonstationary disturbances, as well as presence of elastic deformations in the links of the driven mechanism. In modern systems, adaptive control algorithms have proven themselves as complementary to the main control loops. The article is devoted to the self-adaptive system for controlling of the servo electric drive of prototype's axis of telescope's rotational support device. It's shown that such system has low sensitivity to variations of object's parameters and lets to eliminate vibration in the mode of movement with infralow speed.
‘Chronic’ identities in mental illness

The term ‘chronicity’ is still widely used in psychiatric discourse and practice. A category employed in political, administrative and therapeutic contexts, it guides practitioners’ beliefs and actions. This paper attempts a review of the attitudes and procedures that result as a consequence of identifying ‘chronically’ disturbed identities in clinical practice. An essentially social, relational and materialist understanding of mental illness is used to highlight the kind of thinking underlying the notion of ‘chronic’ identities in day-to-day psychiatric routines. Problematising the notions of singularity and expressiveness, as well as mind/body- and self/other-distinctions, it claims the category itself is responsible for creating a ‘chronic’ kind of being. A spatial metaphor is presented in the conclusion, illustrating a mental strategy by which we can re-shape our thinking about ‘chronic’ identities. It attempts to describe how the shift from an epistemological to a praxeographic approach could build a more complete understanding of mental illness.
Molecular characterization of Echinococcus isolates of cervid origin from Finland and Sweden

The species Echinococcus granulosus is made up of several genotypic strain groups, whose taxonomical classification is still undetermined. Genotypes in the cervid-wolf life-cycle are poorly known, especially in Europe. In this study, 33 Echinococcus isolates from cervids from Finland and Sweden were characterized using mitochondrial ND1 gene sequencing. In addition, phylogenetic analysis of E. granulosus strains using the mitochondrial ATP6, ND1, ND3 and CO1 genes was performed using maximum likelihood, neighbour-joining and maximum parsimony methods. The Finnish and Swedish cervid isolates were found to represent the genotype G10. In the phylogenetic analyses, the camel (G6), pig (G7), cervid (G8) and Fennoscandian cervid (G10) strains clustered in a well-supported monophyletic group. This group differed clearly from the common sheep (G1) and horse (G4, ‘E. equinus’) strains, but was closely related to the cattle strain (G5, ‘E. ortleppi’). Our results support the previous studies suggesting that the genotypes G6-10 should be separated from the species E. granulosus sensu stricto. However, additional morphological studies are needed, and the relationship to the cattle strain (‘E. ortleppi’) should be thoroughly evaluated before a final decision of the taxonomical status of the G6-10 group can be made.
Usability Evaluation of a Collaborative Health Information System - Lessons from a User-centred Design Process

In Norway, a recent health reform urged municipalities to implement new primary health care services for their citizens. In order to optimise resources, municipalities have established inter-municipal coordination (IMC) to collaborate across organisational borders. Information systems become a necessary tool to support collaboration and shared access to information in an IMC. In this context, the research project eHealthextended Care Coordination identified a specific need for a collaborative information system for the process of evaluation and assessment of dementia in IMC teams. This paper presents the usability evaluation of a collaborative information system for dementia assessment built using a user-centred design approach. Mixed methods such as observations, semi-structured interviews and a questionnaire were used for data collection. The results showed that the new information system supported the collaborative work of the inter-municipal dementia team with a sufficient level of satisfaction among the end-users. The prototyped solution established the foundations for the system implemented in the Norwegian trials of the FP7 EU project United4Health, dedicated to Point-of-Care Services.
Influence of Ni˚ NP on the induction of oxidative damage in Triticum vulgare

The influence of spherical nanoparticles (NPs) of nickel Ni° (70±0.3 nm in diameter) in the concentrations of 0.025, 0.05 and 0.1 M on the root part of 4-day-old seedlings of wheat Triticum vulgare wheat has been studied. After treating plants with nanoparticles, an increase was observed in the fluorescence of dichlorofluorescein and malondialdehyde (MDA), as well as strong haphazard DNA degradation down to discrete fragments of flowing nucleotides without forming abnormal apoptotic “ladders”; these effects were directly dependent on the dosage. Fluorescence microscopy and assessment of cell viability by the number of dead cells showed an increase in plant cells death after increasing the number of NPs in the environment, primarily by the way of necrosis.
Electrode-Gap Effects on the Discharge Structure in Atmospheric Radio-Frequency Microplasmas With He/O2 Mixtures

The electrode-gap effects on the discharge characteristics have attracted increasing attention to the design of atmospheric discharge sources. In this paper, a 1-D fluid model is used to explore the discharge structures in atmospheric radiofrequency microplasmas with He/O2 mixture as working gas as well as to discuss the generation of reactive oxygen species (ROS) with the electrode gap varied. As oxygen admixtures are introduced into the helium microplasmas, the heavy anions of O- and O2- become the dominative negative species instead of electrons, and then establish the bulk plasma region together with the positive ions. Thus, even at very small gaps, a normal glow-discharge discharge structure can be formed, and a sheath-dominated discharge structure, which is usually formed in pure helium microplasmas in a small size, cannot be observed any more. The simulation results also indicate that the production of main ROS is more effective in small dimensions.
Video Fire Detection Algorithm using Multi-Feature Fusion

At present, the moving target detection and flame characteristics extraction almost become the most important parts in majority of video fire detection systems. Through the above two-part study, a new fire features detection method is presented in precise moving target area. That is, using the improved background difference method and flame features (such as the color and uniformity, Wavelet energy, stroboscopic and contour features) to detect fire. Experiments show that this method can improve the accuracy and anti-interference ability of fire detection. DOI: http://dx.doi. org/10.11591/telkomnika.v11i10. 3340

Seasonality and diel activity pattern of Glossina morsitans submorsitans ) (Diptera: Glossinidae) in Ghibe River Valley, Southwest Ethiopia

Aspects of the ecology of Glossina morsitans submorsitans inhabiting Ghibe River Valley was studied from October 2000 up to September 2001 with baited monoconical traps. The baits were acetone plus cow urine. Seasonality of the flies were investigated using baited monoconical traps by taking sample every month for five consecutive days for twelve months and diel activity pattern was investigated by taking sample every hour for three consecutive days. The density of G. m. submorsitans was found to be high during wet months and decrease during dry months. It was widely distributed during the rainy season in the savanna woodland; while its distribution was patchy during the dry season. G. m. submorsitans showed a bi-modal daily activity pattern with morning peak followed by mid day depression and then afternoon peak. Its activity rhythm showed a dual relation with temperature, positively correlated in the morning when the temperature is less than 30°C and negatively correlated when temperature is greater than 30°C. Its relation with relative humidity was also both positively and negatively correlated at different time of the day. Key words/phrases : Diel activity, Ghibe River Valley, G. m. submorsitans, seasonality, Southwest Ethiopia SINET: Ethiopian Journal of Science Vol. 27 (2) 2004: 135–142
Hydrophobic residues in small ankyrin 1 participate in binding to obscurin

Abstract Small ankyrin-1 is a splice variant of the ANK1 gene that binds to obscurin A. Previous studies have identified electrostatic interactions that contribute to this interaction. In addition, molecular dynamics (MD) simulations predict four hydrophobic residues in a ‘hot spot’ on the surface of the ankyrin-like repeats of sAnk1, near the charged residues involved in binding. We used site-directed mutagenesis, blot overlays and surface plasmon resonance assays to study the contribution of the hydrophobic residues, V70, F71, I102 and I103, to two different 30-mers of obscurin that bind sAnk1, Obsc6316–6345 and Obsc6231–6260. Alanine mutations of each of the hydrophobic residues disrupted binding to the high affinity binding site, Obsc6316–6345. In contrast, V70A and I102A mutations had no effect on binding to the lower affinity site, Obsc6231–6260. Alanine mutagenesis of the five hydrophobic residues present in Obsc6316–6345 showed that V6328, I6332, and V6334 were critical to sAnk1 binding. Individual alanine mutants of the six hydrophobic residues of Obsc6231–6260 had no effect on binding to sAnk1, although a triple alanine mutant of residues V6233/I6234/I6235 decreased binding. We also examined a model of the Obsc6316–6345-sAnk1 complex in MD simulations and found I102 of sAnk1 to be within 2. 2Å of V6334 of Obsc6316–6345. In contrast to the I102A mutation, mutating I102 of sAnk1 to other hydrophobic amino acids such as phenylalanine or leucine did not disrupt binding to obscurin. Our results suggest that hydrophobic interactions contribute to the higher affinity of Obsc6316–6345 for sAnk1 and to the dominant role exhibited by this sequence in binding.
INDUSTRY 4.0 IMPLICATIONS IN THE AUTOMOTIVE AFTERSALES SECTOR IN SOUTH AFRICA: A LITERATURE REVIEW

Industry 4.0 is currently a hot topic that has gained swift momentum across various industries and disciplines in recent years. It is therefore not surprising that several transformation frameworks have been developed for specific industries, to assist organisations to prepare and align themselves adequately for the change management required to usher them into the next era of Industrial Revolution. This paper provides a literature review of Industry 4.0 in general, where after the implications thereof in the automotive industry, and more specifically the automotive aftersales sector, are discussed. After considering existing Industry 4.0 transformation frameworks, the author proposes a transformation framework for the South African automotive aftersales sector.
Purification and characterization of human H-ras proteins expressed in Escherichia coli

The full-length normal and T24 mutant human H-ras proteins and two truncated derivatives of the T24 mutant were expressed efficiently in Escherichia coli. The proteins accumulated to 1 to 5% of total cellular protein, and each was specifically recognized by anti-ras monoclonal antibodies. The two full-length proteins as well as a carboxyl-terminal truncated derivative (deleted for 23 amino acid residues) were soluble upon cell lysis and were purified to 90% homogeneity without the use of denaturants. In contrast, an amino-terminal truncated ras derivative (deleted for 22 amino acid residues) required treatment with urea for its solubilization. The guanine nucleotide binding activity of these four proteins was assessed by a combination of ligand binding on proteins blots, immunoprecipitation, and standard filter binding procedures. The full-length proteins showed similar binding kinetics and a stoichiometry approaching 1 mol of GTP bound per mol of protein. The showed similar binding kinetics and a stoichiometry approaching 1 mol of GTP bound per mol of protein. The carboxyl-terminal truncated protein also bound GTP, but to a reduced extent, whereas the amino-terminal truncated protein did not have binding activity. Apparently, the carboxyl-terminal domain of ras, although important for transforming function, does not play a critical role in GTP binding.
Horizontal Merger Antitrust Enforcement at the DOJ: A Closer Look From 2005-2015

I manually collect data on all horizontal merger cases litigated by the Department of Justice (DOJ) between 2005-2015 from the DOJ's website by reading the Complaint, Competitive Impact Statement, and Final Judgment for a total of 94 cases. I analyze how horizontal merger antitrust enforcement is impacted by the 2008 Great Recession and the enactment of the 2010 Horizontal Merger Guideline Revision. The total number of mergers litigated by the DOJ decreases from 2008-9 corresponding to the nadir of the Great Recession. The pro-interventionist 2010 Guidelines lead to an increase in merger litigation following its enactment. I use a linear regression to evaluate which factors impact the outcome of the cases following the institution of the Guidelines. I find that when the judge is appointed by a democratic president, the merger is more likely to be blocked, consistent with a pro-enforcement, democratic ideology. Additionally, as the number of anticompetitive reasons against merging increases, the DOJ (plaintiff) is more likely to win. The use of the Hypothetical Monopolist Test (HMT) increases following 2010, and is consisted with the Guidelines’ emphasis on the use of various economic formulas. However, I did not see an increase in the use of other economic formulas. Based on the rationale cited in the Competitive Impact Statement by the DOJ, antitrust litigation appears nonuniform and only minimally effected by the 2010 Guidelines.
