Empowering Teachers with AI: Co-Designing a Learning Analytics Tool for Personalized Instruction in the Science Classroom

AI-powered educational technology that is designed to support teachers in providing personalized instruction can enhance their ability to address the needs of individual students, hopefully leading to better learning gains. This paper presents results from a participatory research aimed at co-designing with science teachers a learning analytics tool that will assist them in implementing a personalized pedagogy in blended learning contexts. The development process included three stages. In the first, we interviewed a group of teachers to identify where and how personalized instruction may be integrated into their teaching practices. This yielded a clustering-based personalization strategy. Next, we designed a mock-up of a learning analytics tool that supports this strategy and worked with another group of teachers to define an ‘explainable learning analytics’ scheme that explains each cluster in a way that is both pedagogically meaningful and can be generated automatically. Third, we developed an AI algorithm that supports this ‘explainable clusters’ pedagogy and conducted a controlled experiment that evaluated its contribution to teachers’ ability to plan personalized learning sequences. The planned sequences were evaluated in a blinded fashion by an expert, and the results demonstrated that the experimental group – teachers who received the clusters with the explanations – designed sequences that addressed the difficulties exhibited by different groups of students better than those designed by teachers who received the clusters without explanations. The main contribution of this study is twofold. First, it presents an effective personalization approach that fits blended learning in the science classroom, which combines a real-time clustering algorithm with an explainable-AI scheme that can automatically build pedagogically meaningful explanations from item-level meta-data (Q Matrix). Second, it demonstrates how such an end-to-end learning analytics solution can be built with teachers through a co-design process and highlights the types of knowledge that teachers add to system-provided analytics in order to apply them to their local context. As a practical contribution, this process informed the design of a new learning analytics tool that was integrated into a free online learning platform that is being used by more than 1000 science teachers.
Overload Behavior of Sheathed Lumber Systems

Computer simulation was used to study the overload behavior of sheathed lumber systems. Simulations included in this study covered two-way action of the sheathing; partial composite action between the sheathing, connectors, and lumber members; the random mechanical properties of the lumber members; and the random postyield properties of the partial composite members. A trilinear spring model and a member-replacement technique were introduced to account for the nonlinear behavior of partial composite members. The primary factors affecting system overload behavior are the variation in the modulus of rupture of the lumber members and the three parameters that describe the postyield properties of the partial composite members. System-failure criteria are developed and are related to the same factors. A distinction is made between brittle-member systems and nonbrittle-member systems. The results apply for uniformly distributed loads applied to the system and do not include the effects of load duration.
Project Management Strategies to Maximize Performance in Exploratory Research: Case Study in Solar Thermal Energy Storage Technology Development

AbstractExploratory research and development projects bring inherent risk due to the unfamiliar nature of the technologies investigated. No consensus exists as to a project management methodology that will consistently add value and increase the rate of success in the exploratory research process. In response to this problem, the authors present observations from their vantage point in the overall project management effort of the design, construction, and engineering of new solar thermal energy storage technologies. The project integrated the efforts of academic institutions, industry representatives, federal energy organizations, and energy utility companies. Based on observations from this case study, the authors propose a project management model to increase performance and more consistently add value in innovative settings such as exploratory technology development projects, specifically with respect to the engineering design and prototyping effort to develop commercially viable technologies. The prop.
Born or Grown: Enablers and Barriers to Circular Business in Europe

Circular economy goals have made their way towards the very heart of EU policy, promising the delivery of both economic and environmental goals, but key to their achievement is the active involvement and participation of businesses. Scholarly literature has made considerable headway in describing the diverse CE business model archetypes and the enablers and barriers that can nurture the transition toward them. However, little work has been done to assess a more profound distinction—that between enterprises that are born circular in contrast with incumbent businesses that grow into circularity. We review 18 case studies of businesses in Europe, which shed light on this distinction. A systematic analysis of their internal, contextual, and policy issues results in the identification of ten key enablers (including business targets, cost reduction potential, loyal customers, demographic aspects, growing waste flows, environmentalism, EU policy, circular policy, and dis/incentives as well as sectoral considerations) and ten key barriers (including bottom line concerns, problematic consumer preferences, lack of infrastructure, technological barriers, poor access to finance, competition, lack of EU harmonisation, uncertainty and lack of internalisation of externalities, and the presence of obstructive policy). We observe that businesses which are born circular seem to face fewer barriers than those seeking to grow into circularity, a finding which offers hope for the transition to a circular economy. Our analysis also suggests that while some enablers and barriers cut across different types of businesses, others tend to be more prevalent among enterprises of a certain size or sector.
Physical Education and Its Importance to Physical Activity, Vegetable Consumption and Thriving in High School Students in Norway

Earlier research indicates that physical education (PE) in school is associated with positive outcomes (e.g., healthy lifestyle, psychological well-being, and academic performance). Research assessing associations with resilience and thriving indicators, such as the 5Cs of Positive Youth Development (PYD; competence, confidence, character, caring, and connection) is limited and more so in the Norwegian context. The aim of the present study was to investigate associations between PE grade (reflecting students’ effort in theoretical and practical aspects of the subject) and the 5Cs as well as healthy behaviors (physical activity (PA), fruit and vegetable consumption), using cross-sectional data collected from 220 high school students in Norway (Mage = 17.30 years old, SD = 1.12; 52% males). Results from structural equation modelling indicated positive associations between PE grade and four of the 5Cs (competence, confidence, caring, and connection; standardized coefficient: 0.22–0.60, p < 0.05) while in logistic regressions, a unit increase in PE grade was associated with higher likelihood of engaging in PA and vegetable consumption (OR = 1.94; 95% CI = 1.18–3.18 and OR = 1.68; 95% CI = 1.08–2.63, respectively). These significant findings suggest the need for policies and programs that can support effective planning and implementation of PE curriculum. However, further research is needed to probe into the role of PE on youth health and development with representative samples and longitudinal designs.
Exploring Critical Success Factors for Partnering in Construction Projects

The construction industry is a very competitive high-risk business. Many problems, such as little cooperation, lack of trust, and ineffective communication resulting in adversarial relationships between contracting parties, are facing the construction industry. Partnering is perhaps one of the most innovative developments in delivering a project efficiently and reducing construction disputes. It provides a sound basis for a “win-win” climate and synergistic teamwork. Project partnering in the Hong Kong construction industry has gained in popularity since 1994. A number of potential factors contributing to partnering success have emerged and deserve further study. This paper presents a review of the development of the partnering concept in general and identifies critical success factors for partnering projects from the Hong Kong perspective in particular. Through a postal questionnaire survey geared toward project participants with hands-on partnering experience, the opinions of various parties—clients, co.
A Transient Heat and Mass Transfer Model of Residential Attics Used to Simulate Radiant Barrier Retrofits, Part I: Development

This paper describes a transient heat and mass transfer model of residential attics. The model is used to predict hourly ceiling heat gain/loss in residences with the purpose of estimating reductions in cooling and heating loads produced by radiant barriers. The model accounts for transient conduction, convection, and radiation and incorporates moisture and air transport across the attic. Environmental variables, such as solar loads on outer attic surfaces and sky temperatures, are also estimated. The model is driven by hourly weather data which include: outdoor dry bulb air temperature, horizontal solar and sky radiation, wind speed and direction, relative humidity (or dew point), and cloud cover data. The output of the model includes ceiling heat fluxes, inner and outer heat fluxes from all surfaces, inner and outer surface temperatures, and attic dry bulb air temperatures. The calculated fluxes have been compared to experimental data of side-by-side testing of attics retrofit with radiant barriers. The model predicts ceiling heat flows with an error of less than ten percent for most cases.
Submersible Aircraft Concept Design Study

This paper presents a summary of the work carried out by the authors whilst on secondment at the Center for Innovation in Ship Design, CISD: a study of the feasibility and conceptual design of a submersible aircraft/flying submarine. A submersible aircraft combines the speed and range of an airborne platform with the stealth of an underwater vehicle. This study explored the feasibility of a design capable of insertion and extraction of Special Forces at greater ranges, at higher speeds, and in locations not previously accessible without direct support from additional military assets. The goal of the study was to find a solution space for a vehicle that can easily transition between airborne, surface, and submerged operations. A variety of technologies were considered. Materials, structures, and equipment that provide the desirable characteristics for both a submerged and airborne platform were exploited to overcome the major challenges offered by a submersible aircraft. A flying scale model was constructed and tested at the David Taylor Model Basin. The work carried out suggests that the concept is feasible and within the current state of the art. The model produced gave confidence in the methods used to scale the propulsive units and in the wing design.
GLUCOSE-6-PHOSPHATASE DEFICIENCY GLYCOGEN STORAGE DISEASE

Three siblings with glycogen storage disease have been studied. These children demonstrated the classic physical findings of von Gierke's disease. Liver enzyme assays on one sibling revealed very low glucose 6-phosphatase activity. Hepatic phosphoglucomutase, phosphorylase, glucose 6-phosphate dehydrogenase, and fructose 1,6-diphosphatase activities were within normal limits. Erythrocyte glucose 6-phosphate dehydrogenase activity was also normal. Incubation of liver slices with glucose 1-C14 and glucose 6-C14 revealed an initial rate of C14O2 production at which CO2 from C-1 was three times that from C-6. This is strong evidence for the active operation of the phosphogluconate oxidation pathway in this patient, and taken with the normal assay value of hepatic glucose-6-phosphate dehydrogenase, constitutes a negation of the concept of a dual enzyme defect recently proposed for von Gierke's disease. Striking elevations of free fatty acids in serum, triglycerides, phospholipids, cholesterol, and blood ketones were noted. Potential mechanisms for these elevations have been discussed. Marked hyperuricemia was a persistent finding and was associated with a somewhat low renal clearance of urate in the one patient studied. All three had striking elevations of lactic acid in blood, which is known to interfere with renal urate excretion. Thus renal factors may have contributed to the hyperuricemia, previously considered solely a consequence of enhanced nucleoprotein catabolism secondary to persistent hypoglycemia. Long-term intramuscular administration of glucagon did not produce significant clinical or laboratory improvement in the one patient in whom it was employed.
Recent Discoveries in Epigenetic Modifications of Polycystic Kidney Disease

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is a heritable renal disease that results in end-stage kidney disease, due to the uncontrolled bilateral growth of cysts throughout the kidneys. While it is known that a mutation within a PKD-causing gene is required for the development of ADPKD, the underlying mechanism(s) causing cystogenesis and progression of the disease are not well understood. Limited therapeutic options are currently available to slow the rate of cystic growth. Epigenetic modifications, including DNA methylation, are known to be altered in neoplasia, and several FDA-approved therapeutics target these disease-specific changes. As there are many similarities between ADPKD and neoplasia, we (and others) have postulated that ADPKD kidneys contain alterations to their epigenetic landscape that could be exploited for future therapeutic discovery. Here we summarise the current understanding of epigenetic changes that are associated with ADPKD, with a particular focus on the burgeoning field of ADPKD-specific alterations in DNA methylation.
The Secondary Use of Data to Support Medication Safety in the Hospital Setting: A Systematic Review and Narrative Synthesis

Objectives: To conduct a systematic review and narrative synthesis of interventions based on secondary use of data (SUD) from electronic prescribing (EP) and electronic hospital pharmacy (EHP) systems and their effectiveness in secondary care, and to identify factors influencing SUD. Method: The search strategy had four facets: 1. Electronic databases, 2. Medication safety, 3. Hospitals and quality/safety, and 4. SUD. Searches were conducted within EMBASE, Medline, CINAHL, and International Pharmaceutical Abstracts. Empirical SUD intervention studies that aimed to improve medication safety and/or quality, and any studies providing insight into factors affecting SUD were included. Results: We identified nine quantitative studies of SUD interventions and five qualitative studies. SUD interventions were complex and fell into four categories, with ‘provision of feedback’ the most common. While heterogeneous, the majority of quantitative studies reported positive findings in improving medication safety but little detail was provided on the interventions implemented. The five qualitative studies collectively provide an overview of the SUD process, which typically comprised nine steps from data identification to analysis. Factors influencing the SUD process were electronic systems implementation and level of functionality, knowledge and skills of SUD users, organisational context, and policies around data reuse and security. Discussion and Conclusion: The majority of the SUD interventions were successful in improving medication safety, however, what contributes to this success needs further exploration. From synthesis of research evidence in this review, an integrative framework was developed to describe the processes, mechanisms, and barriers for effective SUD.
Environmental movements and their political context

Environmental movements are in various ways shaped by their political context, typically conceptualized by scholars as the political opportunity structure (POS). In addition to presenting a review of research on the complex relationship between POS and environmental movements, this chapter provides an analysis of several emblematic climate mobilizations of the late 2010s to elaborate on some largely neglected aspects of POS theory. These include (1) how movements translate POS into strategies through narratives of interactions with governmental institutions; (2) how not only input structures but also output structures of governmental institutions need to be taken into account to understand environmental movements’ strategic choices; and (3) how POS may come to play a less significant role when movements shift from a predominantly instrumental logic to an increasingly moral/expressive logic
Mindful Eating Proficiency and Healthy Eating Literacy among Japanese Mothers: Associations with Their Own and Their Children’s Eating Behavior

Mindfulness is a process of focusing one’s attention on the present moment. Applying this concept to eating (i.e., mindful eating (ME)) is associated with regulated eating behaviors, particularly in people with obesity and who are overweight. Sustaining healthy eating habits requires both healthy eating literacy (HEL) and proficiency in ME. However, ME proficiency in Japanese people has not been sufficiently investigated. In this paper, we conduct a survey of mothers with 4- to 5-year-old children in Aomori City, Japan, to investigate their ME proficiency and HEL level and eating behavior and self-reported body mass index in both mothers and their children from August to September 2019. This study is the first to describe ME proficiency in Japanese mothers. The study sample includes 128 participants from 18 nursery schools. ME proficiency in mothers was positively correlated with both their own and their children’s eating behaviors, thereby suggesting a potential relationship, while strong relationships were not observed between the HEL level and eating behaviors of mothers and children. Improving ME skills, rather than HEL, may be an effective way to sustain healthier eating behaviors in mothers and their children. The level of evidence was Level V: Opinions of respected authorities based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.
The surface energy balance of Austre Lovénbreen, Svalbard, during the ablation period in 2014

The ability to simulate the surface energy balance is key to studying land–atmosphere interactions; however, it remains a weakness in Arctic polar sciences. Based on the analysis of meteorological data from 1 June to 30 September 2014 from an automatic weather station on the glacier Austre Lovénbreen, near Ny–Ålesund, Svalbard, we established a surface energy balance model to simulate surface melt. The results reveal that the net shortwave radiation accounts for 87% (39 W m–2) of the energy sources, and is controlled by cloud cover and surface albedo. The sensible heat equals 6 W m–2 and is a continuous energy source at the glacier surface. Net longwave radiation and latent heat account for 31% and 5% of heat sinks, respectively. The simulated summer mass balance equals –793 mm w.e. , agreeing well with the observation by an ultrasonic ranger.
Review on the Recent Development of Multi-mode Combined Detonation Engine

Abstract In the next few decades, the development of hypersonic aircrafts will be the priority of national defense strategy of many countries, and the significance of the propulsion system applied on the aircraft is self-evident. Hypersonic aircrafts require propulsion devices that can be used independently in a wide range of Mach numbers and flight envelop, however, there have been no such propulsion systems up to now. The multi-mode combined detonation engine, which consists of four modes, is a novel propulsion concept proposed at the beginning of this century for potential application on hypersonic cruise or space access. The multi-mode combined detonation engine is a promising propulsion system which can be used independently in a wide range of Mach numbers and flight envelop. Recently, many countries attach much importance to the research of multi-mode combined detonation engine and great progress has been achieved. This paper attempts to provide an overview of the recent advances in the multi-mode combined detonation engine, and the major progress for each mode is detailed introduced. Nevertheless, there is still a need to pay more attention to the existing problems in the future.
PICO AND FEMTO CELLS DISTRIBUTION EFFECT ON USER ASSOCIATION PERFORMANCE IN 5G HETEROGENEOUS NETWORKS

5G Heterogeneous Networks (HetNet) deployment of low-power with low-cost Small Base Station (SBSs) such as Picocell and Femtocell BS (PBS and FBS) establish a precious solution for improving the musty Macrocell BS (MBS) capacity, reliability, and coverage, etc. This paper studies the effect of SBS distribution on the overall performance of the cellular network. The homogeneous Poisson Point Process (HPPP), Poisson Cluster Processes (PCP), and Matern Cluster Processes (MCP) are considered as distribution models used for this study. The cell association algorithm that is being used in this research is Cell Based Association algorithm (CBA), which is based on Nash Bargaining Solution (NBS). The challenges addressed in this paper feature the work of cell association in heterogeneous networks in three tiers with the perspective of newly emerging WiGig technology. Another challenge addressed in this paper is the consideration of the user distribution method. This paper assumes the user is distributed based on non-uniform user distribution model in which the user density depends on the distance to the associated base stations (BSs). The MCP distribution model achieve optimality (14% & 8% increase in total System Data Rate (SDR) and total Jain's fairness index (JFI) respectively comparison to the HPPP and PCP. The MCP distribution model has the advantage of taking the dependence between Macro and small base stations into consideration. Another advantage of MCP is that the data rate depends on the density of spatial area and is very closely affected by it, as is the case in PCP, while this property is not considered by the PPP distribution model.
