Mobile learning in the workplace. Unlocking the value of mobile technology for work-based education.

The use of mobile phones is attracting considerable interest in the fields of professional learning and work-based education. Surprisingly, there is relatively little systematic knowledge about how mobile devices can be used effectively for learning and competence development in work contexts. Many of the current approaches tend to repackage eLearning content in order to make it suitable for the smaller screens of mobile devices — following behavioural and cognitive paradigms. By contrast, we attempt to illustrate in this chapter how mobile devices allow the realisation of rich pedagogical strategies. We use a number of educational parameters to characterise mobile learning (mLearning) as learning across different contexts that bridges and connects: 1) the creation and sharing of content; 2) learning for and learning at work; 3) individual and social forms of learning; 4) education across formal and informal settings, and (5) situated, socio-cognitive, cultural, multimodal and constructivist educational paradigms. We underpin our arguments with empirical studies from different fields and disciplines of work-based education. In so doing, we conclude that, in addition to sporadic, self-contained training, mobile devices can connect and span different situations and forms of learning and, accordingly, support learners across various contexts and phases of their career trajectories.
A comparative framework for maneuverability and gust tolerance of aerial microsystems

Title of Thesis: A COMPARATIVE FRAMEWORK FOR MANEUVERABILITY AND GUST TOLERANCE OF AERIAL MICROSYSTEMS Renee Campbell, Masters of Science, 2012 Dissertation directed by: Professor J. Sean Humbert Department of Aerospace Engineering Aerial microsystems have the potential of navigating low-altitude, cluttered environments such as urban corridors and building interiors. Reliable systems require both agility and tolerance to gusts. While many platform designs are under development, no framework currently exists to quantitatively assess these inherent bare airframe characteristics which are independent of closed loop controllers. This research develops a method to quantify the maneuverability and gust tolerance of vehicles using reachability and disturbance sensitivity sets. The method is applied to a stable flybar helicopter and an unstable flybarless helicopter, whose state space models were formed through system identification. Model-based static H∞ controllers were also implemented on the vehicles and tested in the lab using fan-generated gusts. It is shown that the flybar restricts the bare airframe’s ability to maneuver in translational velocity directions. As such, the flybarless helicopter proved more maneuverable and gust tolerant than the flybar helicopter. This approach was specifically applied here to compare stable and unstable helicopter platforms; however, the framework may be used to assess a broad range of aerial microsystems.

Insights from the bar: A model of interaction

In order to analyse the behaviour of humans in bars, we did not want to rely on introspective data only, because these may be unreliable [13]. Therefore, we collected natural data from real-life interactions. We recorded a video corpus of unscripted ordering interactions in German clubs. In these recordings, 108 customer-bartender interactions were identified, annotated and analysed. We describe this process in the next section. We continue with a comparison of the real data and introspective data that was collected in an online survey. 4 Video corpus The video recordings were conducted in the bar areas of several club locations in Germany. We acquired high quality recordings of the bartenders’ and the customers’ perspective and speech by using two HD cameras (Sony PMW-EX3) and two boundary layer microphones. The recorded area covered about three to four barstools and
Quality of Life in Patients Rehabilitated with Implant-Supported Prostheses – A Systematic Review

Abstract Oral health-related quality of life can be defined as the perception of the impact that oral health has on the quality of life. The quality of life is characterized by a person’s perception of his/her social status and the activities he/she carries out in daily life, in relation to his/her standards, objectives, concerns and expectations, as well as the system of values and cultural conditions within he/she lives in. Objective: The objective of this study was to systematically review the dental literature to identify and classify relevant articles on the quality of life associated with the oral health of patients rehabilitated with implant-supported prostheses. Materials and methods: A systematic search of the literature on PubMed was performed for articles published between 2000 and 2021. The main method used was the electronic search using keywords such as: “quality of life”, “dental implant”. The articles found were subject to inclusion and exclusion criteria. Results: Following a systematic search, a total of 249 publications were identified, of which only 9 met the inclusion criteria. Discussions: A small number of studies were found to meet the inclusion criteria and to present high levels of evidence. Therefore, more research in the field is recommended, as current research on quality of life in patients rehabilitated with implant-supported prostheses is still in the development phase. Conclusions: The quality of oral health could have an impact on patients’ daily lives and dental satisfaction (satisfaction with dental appearance, pain perception levels, oral comfort, functional performance and chewing capacity). Patients’ satisfaction with their dentition has a definite impact on the quality of daily life and perceptions of oral health.
Performance analysis of a CDMA wireless local loop systems

In this paper, the capacity of the Code Division Multiple Access Wireless Local Loop (CDMA WLL) system is analytically derived, and the capacity gain achieved in a CDMA WLL over a cellular mobile environment is calculated. The results show that the CDMA WLL system can support up to 36 % more users than CDMA cellular mobile system. The paper also propose a new approach to increase the reverse link capacity of the CDMA WLL system, which synchronize the reverse link so that signals transmitted from different subscriber units within the same cell are time aligned at the base station (BS). A theoretical analysis of the potential capacity gain of reverse link synchronous CDMA WLL is presented.
Development of the Improved Helicopter Icing Spray System (IHISS)

Boeing Helicopters has been awarded a contract by the U.S. Army to design, fabricate and test a replacement for the existing Helicopter Icing Spray System (HISS). The Improved Hiss (IHISS), capable of deployment from any CH-47D helicopter, will include new icing spray nozzles and pneumatic pressure source, and a significantly larger water tank and spray boom. Results are presented for extensive bench and icing tunnel test programs used to select and modify an improved spray nozzle and validate spray boom aerodynamic characteristics. The resulting system will provide a significantly larger icing cloud with droplet characteristics closely matching natural icing conditions.
A Method for Tailback Approximation Via C2I-Data Based on Partial Penetration

Optimizing traffic flow at signalized intersections is one approach to manage increasing traffic volume in metropolitan areas. This paper offers a method to use available C2I-communication data for tailback length approximation in urban networks. Tailback length can be used as criterion to be optimized within signal control methods, and can also be used for providing individual driver information like the optimal speed to pass the signalized intersection without needing to stop. The method merges current and historical C2I-communication data with information of the signal control in the access lanes and is implemented into the microscopic traffic simulator AIMSUN NG. The authors contend that even a low penetration rate of vehicles with communication tools is sufficient to obtain a reliable approximation. They conclude that, based on the good performance of the method so far, the currently used fixed time signal control will be changed into a traffic-responsive control strategy based on approximate dynamic programming techniques.
The pricing of earnings and cash flows in the presence of abnormal and normal accruals

Abstract This paper proposes a framework to assess the effects of abnormal and normal accruals on the valuation relevance of earnings and cash flows. We use this framework to investigate the relative weights placed by investors on earnings and cash flows, as a function of estimated normal and abnormal accruals. Assuming that the construct capitalised by investors is (unobservable) economic earnings, and that normal accruals capture the noise in cash flows as a measure of economic earnings, while abnormal accruals capture the noise in reported earnings as a measure of economic earnings, we predict that normal accruals (abnormal accruals) reduce the valuation weights placed by investors on cash flows (earnings). We find that abnormal accruals estimated using a modified version of the Jones (1991) model are associated with lower valuation weights placed on earnings. Results for the cash flow prediction are mixed, in that the valuation weight placed on cash flows in the presence of high magnitudes of normal accruals is lower when abnormal accruals are negative, but not when abnormal accruals are positive. © City University of Hong Kong.

Cognitive and Behavioral Task Implications for Three-Dimensional Displays Used in Combat Information/Direction Centers

Abstract : This report discusses an investigation to determine which tactical information should be displayed in three dimensions (3-D), as visualized data that would be beneficial to the warfighter's understanding of the battlespace. A cognitive task analysis was conducted using warfighting personnel from Surface Warfare Officer's School (SWOS), Joint Maritime Command Information System (JMCIS) instructors at Navy Technical Training Center, Corry Station, and participants at the "All Service Combat Identification and Evaluation Team, 1997" combat training exercise. Our task analysis found that a 3-D display could enhance situation awareness by providing a succinct, comprehensive, and readily discernable presentation of the common tactical picture. 3-D displays could aid tactical decisionmakers in three general cognitive/perceptual areas: (1) assessing the force structure of friends, neutrals, possible adversaries, and noncombatants, (2) anticipating possible future actions based upon capabilities, historical precedent, and current political climate, and (3) refining and rehearsing contingency plans based on an assessment of the possible threat. Our analysis examined these processes and determined that a 3-D display could provide enhancement in submarine and mine location/interdiction, amphibious assault/land support, and air warfare planning and execution.
Analysis of differential gene expression of heart failure based on Gene Expression Omnibus database

Background To screen and identify key genes involved in heart failure and explore underlying molecular mechanisms. Methods The expression profile of GSE26887 was downloaded from Gene Expression Omnibus (GEO), which contained 24 samples, including 19 left ventricle cardiac tissue of heart failure and 5 controls. The differentially expressed genes (DEGs) were obtained and got further analysis by bioinformatics methods. The DEGs and volcano plot were acquired with the use of ‘lima’ package in ‘R’ software and heat map was drawn through the ‘heatmap’ package. Gene ontology (GO) and pathway analysis of DEGs were performed by means of Database for Annotation, Visualization and Integrated Discovery (DAVID) and Kyoto Encyclopedia of Genes and Genomes (KEGG) online analyses, respectively. The DEGs interaction and network map were constructed through Search Tool for the Retrieval of Interacting Genes (STRING ) database and Cystoscope(v3.6.0)software. Results The transcriptome analysis of left ventricle cardiac tissue showed that 236 genes were differentially expressed between heart failure and control, of which 124 were significantly upregulated (P < 0.01) and 101 genes downregulated (P < 0.01). GO analysis uncovered that DEGs were enriched in extracellular space, extracellular matrix, extracellular matrix organization, cell adhesion, proteinaceous extracellular matrix and heparin binding. Thus, the function of extracellular matrix is mainly affected. The KEGG pathway enrichment indicated that the DEGs were involved in eight pathways, of these pathways, ECM-receptor interaction, Drug metabolism-cytochrome P450 and Pathogenic Escherichia coli infection are dominant. Protein-protein interaction (PPI) revealed the interactions of 30 protein products encoded of DEGs. Of the 30 protein products, the critical gene, called Interleukin-6 (IL6), was identified with the use of Cystoscope software. Conclusion Extracellular matrix and IL6 play an important role in the development of heart failure. Functional annotation and pathway analysis of these main genes were identified, which provide the basis for insight into the underlying pathogenetic mechanisms and predicting therapeutic targets of heart failure.
Research on Security of Transportation Network to Emergency Logistics

The security of transportation network has an important effect on the efficiency of emergency logistics. It is not only relevant to the topological structure of networks, but also to the ways that attack networks. The thesis, based on complex network theory and graph theory, analyzed the effect on the security of transportation network of emergency logistics respectively caused by cut vertex attacks, cut edge attacks and avalanche attacks with following conclusions. First, there is a worse breakage for homogeneous transportation network (like networks of railway, highway and waterway) than for inhomogeneous ones (like network of airway) causes by cut edge attacks. Second, there is little difference among different types of networks in security when attacked by cut vertex attacks at random. Third, cut vertex attacks' effect on the security of inhomogeneous transportation networks is bigger than that on homogeneous ones. Forth, to avalanche attack, there are critical thresholds for security in all kinds of networks, but the security of inhomogeneous transportation networks is worse than that of homogeneous ones.

Broadband Quantum Interface using a Thulium-doped Waveguide

Quantum communication allows one to perform tasks, such as provable secure key distribution, that are impossible in traditional communication. However, to increase the usefulness of implementations of quantum communication, the communication distance must be increased beyond its current limit of around one-hundred kilometers. To this end, a quantum memory must be constructed for use in a quantum repeater. This thesis concerns the spectroscopic characterization of a novel material candidate for quantum memory: a thulium doped lithium niobate waveguide cooled to 3 Kelvin. Furthermore, the possibility to reversibly transfer quantum states from sub-nanosecond, faint pulses of light in and out of this solid state device is demonstrated. This work extends the current benchmarks for storage bandwidth and multimode capacity, both required for high rate quantum communications. In addition, the integrated approach bridges the gap between fundamental and applied research into quantum memory.
Numerical Study of Liquid Film Formation around Tubes of Horizontal Falling Film Evaporator

Falling film evaporative heat exchangers are extensively used in processing industries; broad areas of application being refrigeration, desalination and food processing industries. The fundamental aspect of this type of heat transfer process is to extract the process heat in the form of latent heat by liquid which is sprayed over the surface of the process tubes. Formation of liquid film over a fully wetted horizontal round tube of falling film evaporator has been numerically simulated here. Two numerical approaches, Volume of Fluid (VOF) technique and the Eulerian multiphase model are applied to compare their results. The effect of varying flow and geometrical parameters on the film thickness is investigated. Two horizontal tubes of diameter 19.05mm and 25.04mm with three different uniform spacing have been selected for simulation. Film Reynolds numbers 650, 950 and 1250 are considered for the above set of parameters. Ii is observed that the geometrical and flow parameters considerably influence the film thickness. Transient analysis of the film formation has been carried out and parameters like pathline of liquid film and the velocity profile have been obtained for understanding the flow behavior in a better manner. All the simulated results agree well with the published data.
Context or No Context? A preliminary exploration of human-in-the-loop approach for Incremental Temporal Summarization in meetings

Incremental meeting temporal summarization, summarizing relevant information of partial multi-party meeting dialogue, is emerging as the next challenge in summarization research. Here we examine the extent to which human abstractive summaries of the preceding increments (context) can be combined with extractive meeting dialogue to generate abstractive summaries. We find that previous context improves ROUGE scores. Our findings further suggest that contexts begin to outweigh the dialogue. Using keyphrase extraction and semantic role labeling (SRL), we find that SRL captures relevant information without overwhelming the the model architecture. By compressing the previous contexts by ~70%, we achieve better ROUGE scores over our baseline models. Collectively, these results suggest that context matters, as does the way in which context is presented to the model.
Quantifying Contextual Aspects of Inter-annotator Agreement in Intertextuality Research

We report on an inter-annotator agreement experiment involving instances of text reuse focusing on the well-known case of biblical intertextuality in medieval literature. We target the application use case of literary scholars whose aim is to document instances of biblical references in the ‘apparatus fontium’ of a prospective digital edition. We develop a Bayesian implementation of Cohen’s kappa for multiple annotators that allows us to assess the influence of various contextual effects on the inter-annotator agreement, producing both more robust estimates of the agreement indices as well as insights into the annotation process that leads to the estimated indices. As a result, we are able to produce a novel and nuanced estimation of inter-annotator agreement in the context of intertextuality, exploring the challenges that arise from manually annotating a dataset of biblical references in the writings of Bernard of Clairvaux. Among others, our method was able to unveil the fact that the obtained agreement depends heavily on the biblical source book of the proposed reference, as well as the underlying algorithm used to retrieve the candidate match.
Influence of user personality on dialogue task performance: A case study using a rule-based dialogue system

Endowing a task-oriented dialogue system with adaptiveness to user personality can greatly help improve the performance of a dialogue task. However, such a dialogue system can be practically challenging to implement, because it is unclear how user personality influences dialogue task performance. To explore the relationship between user personality and dialogue task performance, we enrolled participants via crowdsourcing to first answer specified personality questionnaires and then chat with a dialogue system to accomplish assigned tasks. A rule-based dialogue system on the prevalent Multi-Domain Wizard-of-Oz (MultiWOZ) task was used. A total of 211 participants’ personalities and their 633 dialogues were collected and analyzed. The results revealed that sociable and extroverted people tended to fail the task, whereas neurotic people were more likely to succeed. We extracted features related to user dialogue behaviors and performed further analysis to determine which kind of behavior influences task performance. As a result, we identified that average utterance length and slots per utterance are the key features of dialogue behavior that are highly correlated with both task performance and user personality.
