Online Education Patterns, Part 1: Patterns for Linking Separate Worlds

In this paper, the core pattern and 12 patterns for LINKING SEPARATE WORLDS from Online Education Patterns are presented. Online Education Patterns consists of 37 patterns for creating great online classes. Instead of mimicking the ways of teaching in a real classroom to online, the most important thing to keep in mind is Redesigning for Online Learning, and this can be realized by LINKING SEPARATE WORLDS, CREATING A NEW FORM OF LEARNING and BUILDING A SENSE OF BELONGING. This paper focuses on patterns for LINKING SEPARATE WORLDS, which are patterns to link students and teachers who can feel physically and mentally distant as they participate in online classes remotely. By mining the experiences of 25 teachers who have already made efforts to initiate great online learning at university, high school, junior high school, and elementary school, we came to the following findings; Think of online classes as a VISUAL RADIO where students are listeners who are listening from far away; In order to make the class more attractive, DRAWING STUDENTS INTO THE CLASSROOM ATMOSPHERE helps them switch their focus from daily life activities at home to the class in front of them; Although students and teachers are distant, FEELING EACH OTHER'S PRESENCE will make everyone feel that they are taking the class together; Creating opportunities for INTERACTION BETWEEN STUDENTS can then further link students together as well as deepen their learning. To realize the above, this paper presents the following 13 patterns: Redesigning for Online Learning, Radio Host Spirit, Asynchronous Interaction, Operation Team, Inviting Opening, Sharing Excitement, Reaction Members, Encouraging Cameras On, Written Voices, Priming Water for Chat Flow, Casual Talk Time, Conversation Starter, and Same Members.
A Security Property Decomposition Argument Pattern for Structured Assurance Case Models

Demonstrating that a system satisfies a complete, adequate, and consistent set of security requirements to protect its critical assets is an essential aspect of security evaluation and assurance. Arguing that each of the security properties for a given system is satisfied and supported by evidence is a requirement for presenting an effective and compelling security assurance argument. The decomposition of a security assurance case to support this argumentation can be challenging as different systems have different security objectives and, consequently, different security requirements. In this paper, we propose a security assurance argument pattern called Security Property Decomposition. This pattern is extracted by studying existing security assurance case models and their decomposition to argue the satisfaction of security properties such as confidentiality, integrity, and availability. It also considers the requirements prescribed by several prominent security standards for developing secure and trustworthy systems in different application domains. As a result, the Security Property Decomposition pattern can be instantiated in the context of different application domains to demonstrate that the security requirements related to the functionality of the system have been adequately satisfied as part of a structured security assurance case. To illustrate the applicability of the proposed pattern, we present an application of the pattern demonstrating compliance with a relevant security standard in the automotive domain.
Some Patterns for Architecting Lectures

∗ Lecturing is one of the oldest instructional methods. In the current scenario, lecturing is taking place both in online as well as in offline mode. In both modes crafting a pedagogically effective lecture for learners is not an easy task. This research tries to address this problem. This research discovers three patterns that help in architecting pedagogically effective lectures. Generally, a standard lecture lasts from 45 to 90 minutes. In online education, learners often fail to maintain concentration for such a long period. So need for a short lecture arises. This need leads to the development of 1-3 minutes long lectures known as micro-lectures (MIL). The first two patterns focus on designing issues associated with micro-lectures. These patterns help in designing assignment free micro-lectures. The third pattern explores how programming language associated lectures are designed. We strongly believe that the patterns discussed in this paper help online educators in designing pedagogically effective lectures.
Minimum Leaf Conductance (gmin) Is Higher in the Treeline of Pinus uncinata Ram. in the Pyrenees: Michaelis’ Hypothesis Revisited

The search for a universal explanation of the altitudinal limit determined by the alpine treeline has given rise to different hypotheses. In this study, we revisited Michaelis’ hypothesis which proposed that an inadequate “ripening” of the cuticle caused a greater transpiration rate during winter in the treeline. However, few studies with different explanations have investigated the role of passive mechanisms of needles for protecting against water loss during winter in conifers at the treeline. To shed light on this, the cuticular transpiration barrier was studied in the transition from subalpine Pinus uncinata forests to alpine tundra at the upper limit of the species in the Pyrenees. This upper limit of P. uncinata was selected here as an example of the ecotones formed by conifers in the temperate mountains of the northern hemisphere. Our study showed that minimum leaf conductance in needles from upper limit specimens was higher than those measured in specimens living in the lower levels of the sub-alpine forest and also displayed lower cuticle thickness values, which should reinforce the seminal hypothesis by Michaelis. Our study showed clear evidence that supports the inadequate development of needle cuticles as one of the factors that lead to increased transpirational water losses during winter and, consequently, a higher risk of suffering frost drought.
Defining a Standard Set of Health Outcomes for Patients With Squamous Cell Carcinoma of the Head and Neck in Spain

Purpose A systematic, standardized collection of health outcomes during patient treatment and follow-up, relevant from the perspective of all stakeholders, is a crucial step toward effective and efficient disease management. This project aimed to define a standard set of health outcomes for patients with squamous cell carcinoma of the head and neck (SCCHN). Methods The project was led and coordinated by a scientific committee (SC). It comprised: (1) a literature review (to identify variables used during SCCHN management); (2) 1st-SC meeting (to select the variables for presentation during nominal groups-NG); (3) five NG (n=42 experts) and four interviews with patients (to reach consensus on the variables for inclusion); and (4) final-SC meeting (to review the results of NG ensuring consensus on the variables where consensus was not reached). Results Experts agreed to include the following variables in the standard set: treatment-related (treatment intent and type, response to treatment, treatment toxicity/complication, treatment completion), degree of health (performance status, patient-reported health status, pain, dysphonia, feeding and speech limitations, body image alteration, tracheotomy), survival (overall and progression-free survival, cause of death), nutritional (weight, nutritional intervention), other variables (smoking status, alcohol consumption, patient satisfaction with aftermath care, employment status), and case-mix variables (demographic, tumor-related, clinical and nutritional factors). Conclusions This project may pave the way to standardizing the collection of health outcomes in SCCHN and promote the incorporation of patients’ perspective in its management. The information provided through the systematic compilation of this standard set may define strategies to achieve high-quality, patient-centered care.
The Impact of Business Analytics on Management Accounting

Purpose – The purpose of this paper is to speculate on the potentials of combining management accounting with the idea of business analytics. Or more specific how the three stages of business analytics can be used for combining the balanced scorecard with other related accounting concepts. Design/methodology/approach – The work is based on research literature and surveys provided by researchers and consultants within business analytics and the balanced scorecard.Findings – Kaplan and Norton as well as other researchers within business analytics have pointed to the unresolved issue of how to integrate different accounting model such as activity-based costing, lean etc., into the BSC. Such a holistic framework – e.g. expressed as a mathematical computer simulation model – would give the decision-maker a strong tool for do statistical testing and learn about the influences of different KPIs in decision making.Practical implications – The paper provides information and consideration on how to move from a simple descriptive approach to the more advanced level of prescriptive level in business analytics by using the arsenal of different quantitatively tools that are available. Subsequently, it provides some reflections on the skills that future accountants must possess to be able to fulfill their future role. Originality/value – The value of this paper is two-fold: first, it shows that relying on business analytics and its systematic methodological approach will open up new possibilities for management accountants; second, it shows that by integrating the principles of business analytics and the BSC framework it is possible to develop a comprehensive data-driven approach to dynamic performance management relevant for decision making.
Profiling Phenolic Composition in Pomegranate Peel From Nine Selected Cultivars Using UHPLC-QTOF-MS and UPLC-QQQ-MS

Pomegranate is widely cultivated across China, and the phenolics in its peel are principal components associated with health benefits. Ultra-high performance liquid chromatography coupled to a quadrupole time-of-flight mass spectrometer (UHPLC-QTOF-MS) and ultra-performance liquid chromatography coupled to a triple quadrupole mass spectrometer (UPLC-QQQ-MS) were used in this study, aiming at profiling the total phenolic composition in pomegranate peel from nine selected cultivars in 7 production areas. Sixty-four phenolic compounds were identified or annotated, and 23 of them were firstly reported in pomegranate peel. Principal component analysis (PCA) plots show differences and similarities of phenolics among nine cultivars. Furthermore, 15 phenolic compounds were quantified with the standards, and punicalagin, ellagic acid, gallocatechin, punicalin, catechin, and corilagin were found to be dominant. Punicalagin weighed the highest content (28.03–104.14 mg/g). This study can provide a deeper and more detailed insight into the phenolic composition in pomegranate peel and facilitate the health-promoting utilization of phenolics.
Problem Mechanism and Solution Strategy of Rural Children’s Community Inclusion—The Role of Peer Environment and Parental Community Participation

Early childhood development intervention has gained considerable achievements in eliminating intergenerational transmission of poverty in rural areas. Paying further attention to rural children’s community inclusion can also promote the sustainable development of the village. However, there is a lack of systematic theoretical constructs on the village inclusion of rural children. In this study, an attempt was made to explore the problem mechanism and solution strategy of community inclusion of rural children using a grounded theory approach of in-depth interviews. Seventeen parents of children in a national-level poverty-stricken county in Inner Mongolia of China were investigated, adopting the strategy of intensity sampling. The results revealed that (1) the content of rural children’s activities demonstrates enhanced participation in the virtual environment and weakened participation in the real community environment. That is, the activities are characterized by more virtualization and individualization. (2) Rural parents and community peers are two major channels for children’s community inclusion, while both the community peer environment and parental community participation show a weakening trend. This may be an important reason for the virtualization and individualization of the children’s psychological development environment. (3) Developmental intervention programs for rural children in poverty-stricken areas should focus on the reconstruction of children’s community peer environment, encourage the community participation of parents, and fully mobilize local-based educational resources.

Diagnostic Value of Serum Concentration of Galectin-3 in Patients With Heart Failure With Preserved Ejection Fraction

Background Although the predictive value of galectin-3 for heart failure with preserved ejection fraction has been demonstrated, the diagnostic value remains unclear. The present study was performed to address this issue. Hypothesis Galectin-3 has diagnostic value for heart failure with preserved ejection fraction. Methods This is a diagnostic experiment. We conducted an observational study of 223 patients with combined symptoms of heart failure and diseases that can lead to heart failure with preserved ejection fraction. Patients were grouped into the heart failure group and control group in accordance with the 2016 European Society of Cardiology heart failure guidelines for heart failure with preserved ejection fraction. Baseline information and serum galectin-3 concentration were assessed within 24 h after admission. Results Serum galectin-3 concentration was significantly higher in the heart failure group compared with the control group. Binary logistic regression analysis showed that higher galectin-3 concentration was associated with the occurrence of heart failure with preserved ejection fraction. The area under the curve of galectin-3 was 0.763, indicating that galectin-3 has moderate diagnostic value for heart failure with preserved ejection fraction. Galectin-3 >15.974 ng/mL identified heart failure with preserved ejection fraction with 76.0% sensitivity and 71.9% specificity. Conclusions There was a correlation between galectin-3 and heart failure with preserved ejection fraction, and galectin-3 was an independent predictor of heart failure with preserved ejection fraction. The diagnostic value of galectin-3 for heart failure with preserved ejection fraction was moderate (AUC: 0.763, 95% CI: 0.696–0.821, P < 0.01, and the sensitivity is 76.0% while the specificity is 71.9% at the threshold 15.974 ng/mL) and was higher than that of interventricular septal thickness or E/A ratio.
Simulation Study of Heavy Haul Train Operation on Datong-Qinhuangdao Railway

Based on the real conditions of Datong-Qinhuangdao Line,the simulation model of heavy haul train is established,through which the traction,braking and other technical parameters are studied for heavy haul trains with different formations.The purpose of simulation study is to provide technical basis for organizing heavy haul train test,framing reasonable train operation method,and ensuring the safe,reliable,punctual,efficient and energy saving operation.Simulation calculation shows that equipped with LOCOTROL and operated according to reasonable methods,20 000 t combined heavy haul train of different formations,including 1+2+1 style and 4×5 000 t style train driven by SS4,1+1+0 style driven by HXD1,can satisfy the requirement of time schedule and charging time for cycle brake on long steep downgrade.The maximum longitudinal force occurred in 20 000 t train during emergency brake and service brake for 1+1+0 style train driven by HXD1 locomotive is a little bit larger than that of 1+2+1 style train driven by SS4 locomotive.Generally,the maximum longitudinal force is less than 2 000 kN during emergency brake.The maximum longitudinal force under service brake case is about 1 000 kN.There is safety margin for both cases.Simulation results and test results match well.Simulation study provides technical support for successfully operating 20 000 t combined heavy haul train on Datong-Qinhuangdao Line.
Task-related changes in aperiodic activity are related to visual working memory capacity independent of event-related potentials and alpha oscillations

Individual differences in visual working memory capacity are related to slow-wave event-related potentials (ERPs) and suppression of alpha-band oscillatory power measured during the delay period of memory tasks using electroencephalography (EEG). However, recent evidence suggests that changes in the non-oscillatory, aperiodic features of the EEG signal may also contribute to working memory performance. We assessed several features of task-related changes in aperiodic activity including the spatial distribution, the effect of memory load, and the relationship between memory capacity, slow-wave ERPs, and alpha suppression. Eighty-four healthy individuals performed a continuous recall working memory task consisting of 2, 4 or 6 coloured squares while EEG was recorded. Aperiodic activity during a baseline and delay period was quantified by fitting a model to the background of the EEG power spectra using the FOOOF toolbox, which returned parameters describing the slope (exponent) and broadband offset of the spectra. The aperiodic exponent decreased (i.e., slope flattened) over lateral parieto-occipital electrodes but increased (i.e., slope steepened) over fronto-central electrodes during the delay period, whereas the offset decreased over parieto-occipital electrodes. These task-related changes in aperiodic activity were not altered by memory load. Larger increases in the aperiodic exponent were associated with higher working memory capacity measured from both the EEG task and a separate battery of complex span tasks, and this relationship was independent of slow-wave ERPs and alpha suppression. Our findings suggest that task-related changes in aperiodic activity during working memory are region specific and reflect an independent neural mechanism important for general working memory ability.

Universal cyber physical system, a prototype for predictive maintenance

Industrial 4.0 technology of cyber-physical system enables real-time monitoring, sensing and actuating of physical machinery for predictive maintenance that replaces the conventional labor-intensive approach. This paper presents the design and development of a universal, cost-effective and internet of thing (IoT)-based proof-of-concept prototype universal cyber-physical system (UniCPS) with a cloud platform with an open and modular-based design of three-tier system architecture. The prototype demonstrates promising precision and accuracy for predictive maintenance on a pilot use case with MAPE of 3.77%, and average RMSE of 0.50. Besides, real-time visualization and detection of anomaly were also demonstrated with a cloud-based solution. The maintenance alert sent out by the actuator serves to notify the authorized personnel immediately for corrective action. As an extension to this work, a wireless sensor network can be incorporated in future work to acquire various data from diverse locations to overcome the limitations of sensor data.
Redirected free exploration with distractors: a large-scale real-walking locomotion interface

Immersive Virtual Environments (VEs) enable user controlled interactions within the environment such as head-controlled point-of-view and user-controlled locomotion. In the real world people usually locomote by walking; walking is simple and natural, and enables people not only to move between locations, but also to develop cognitive maps, or mental representations, of environments. People navigate every day in the real world without problem, however users navigating VEs often become disoriented and frustrated, and find it challenging to transfer spatial knowledge acquired in the VE to the real world. In this dissertation I develop and demonstrate the effectiveness of a new locomotion interface, Redirected Free Exploration with Distractors (RFED) that enables people to freely walk in large scale VEs. RFED is the combination of distractors—objects, sounds, or combinations of objects and sounds in the VE that encourage people to turn their heads, and redirection—making the user turn herself by interactively and imperceptibly rotating the virtual scene about her while she is turning her head. I demonstrate through user studies that compare RFED to a real-walking locomotion interface that RFED does not diminish user ability to navigate. I further demonstrate that users navigate better in RFED than with joystick and walking-in-place locomotion interfaces. Additionally, RFED does not significantly increase simulator sickness when compared to real walking, walking-in-place, and joystick interfaces.
