Subjects: subject: Transportation Engineering

description: Since 1951 the Division of Research has been engaged in a comprehensive study of highway drainage problems. This study has included special investigations of rainfall and runoff, drainage structures in use and the practices used in their design, culvert hydraulics, and other relevant investigations. To date, reports have been published concerning runoff and rainfall variables (1 and 2)* and the effects of barrel roughness upon culvert operation (3), together with the preparation of a drainage manual for the use of Highway Department engineers and consultants.  The most recent special project, part of the over-all study, has dealt with the effects of inlet geometry upon the operation of culverts under entrance control. The procedures of this study have been somewhat unique in that they have made use of a scale model of a box culvert, set up in such a way that its operation could be closely observed and accurate readings could be made of water pressures, discharge quantities and the like. Although rather summarily reported on previously (4), the methods, underlying theories and results of this study are the subject of this report.

description: Problem-based learning has a long history of transforming higher education institutions at course-, curriculum- and even systemic levels, and has shown to enhance student-centered learning and core pedagogical values such as facilitating collaboration, complex problem-solving skills and critical thinking. However, rapid digitalisation in higher education and emerging trends such as personalised life-long learning through micro-credentials and flexible curriculum models challenges existing, traditional onsite PBL practices and require new frameworks for envisioning future practice in higher education based on an understanding of its local context and the inclusion of multiple relevant stakeholders and practitioners, not only to co-create potential scenarios suitable for a particular educational institution but also in pointing to directions for initiating and maintaining this change process on a systemic level. In this paper, we propose normative scenario thinking as a method for educational development, and present the first steps and initial findings from a process of normative scenario development within a PBL university. The aim of this process has been to identify and explore key trends and core values that inform the development of future scenarios for the conceptualisation and implementation of PBL at the university, in a digital age. Through the analysis of a specific scenario related to project variation and reflection, we exemplify how a value-based and problem-oriented approach to exploring emerging PBL futures can facilitate systemic change in higher education.

description: This paper presents a holistic model which can be used to help teachers to design pedagogical opportunities for meaningful reflections in higher education. Within the PBL Future initiative of Aalborg University, we worked with a group of students from different study programmes and levels. In a three-semester long process these students engaged in a series of reflective activities aimed at helping them become more aware of their professional competence developments. In an iterative process we analysed their reactions to and interactions with a set of given reflective tasks (both face-to-face and online), and with the research team. We summarise our insights into the complex dynamics of reflective processes in a model which conceptualises reflections as taking place as interplay between opportunities, challenges, tools and helpful relations, and with inspiration from the outside world.

description: Starting from the first renormalized factorization theorem for a process described at subleading power in soft-collinear effective theory, we discuss the resummation of Sudakov logarithms for such processes in renormalization-group improved perturbation theory. Endpoint divergences in convolution integrals, which arise generically beyond leading power, are regularized and removed by systematically rearranging the factorization formula. We study in detail the example of the $b$-quark induced $h\toγγ$ decay of the Higgs boson, for which we resum large logarithms of the ratio $M_h/m_b$ at next-to-leading logarithmic order. We also briefly discuss the related $gg\to h$ amplitude.

description: Organizing a coherent PBL semester where courses and project work are integrated and supporting the development of both disciplinary and generic competences is difficult. In this study we investigate how integration can be supported by different IT initiatives. Applying a practice theoretical approach, inspired by Stephen Kemmis, this article analyses how the practice activities and the resources within the practice are constituting challenges and possibilities for an integrated PBL practice. The findings of the study illuminate possibilities in reorganizing a semester structure with focus on creating a shared language to support communication and establishing solidary ways of relating. An important issue is also to have focus on the dispositions to act within the actual IT based materiality.

Progression of Self-Directed Learning in PBL

Publisher: name: Journal of Problem Based Learning in Higher Education
Year: 2021

description: The purpose of this article is to describe the results from an investigation of the development of students' attitudes and behaviours conducive to self-directed learning (SDL) in problem-based learning. The article reports the results from an application of a newly validated statistical instrument to measure self-directed learning on bachelor students in sociology and data science, comparing first-, second- and third-year students. The results are analysed through factor analysis and by comparing mean scores across the three generations of students. The results suggest that the students develop their SDL attitudes and behaviours through their first three years at a Problem-based learning (PBL) university, but also show that this is not a linear or uniform process. The results of the factor analysis show that the students develop their ability to be self-regulating during their second year and move towards a more internal locus of control during their third year.

description: Conservation organizations set priorities as a balance of their overall mission and the larger conservation needs. As we craft conservation strategies across ever-larger landscape scales, we need to understand and incorporate conservation priorities that span different organizations, geographies, management plans, and jurisdictional boundaries.

description: Few-layer selenium and tellurium films have been recently prepared, and they provide a new platform to explore novel properties of two-dimensional (2D) elemental materials. In this work, we have performed a systematic first-principles study on the electronic, linear, and nonlinear optical (NLO) properties of atomically thin selenium and tellurium films within the density-functional theory with the generalized gradient approximation plus scissors correction using the band gaps from the relativistic hybrid Heyd-Scuseria-Ernzerhof functional calculations. Interestingly, we find that few-layer Se and Te possess large second-harmonic generation (SHG), linear electro-optic effect, and bulk photovoltaic effect. In particular, trilayer (TL) Te possesses large SHG coefficient, being more than 65 times larger than that of GaN, a widely used NLO material. Bilayer (BL) Te has huge static SHG coefficient, being more than 100 times larger than that of GaN. Furthermore, monolayer (ML) Se possesses large SHG coefficient. Moreover, we predict that TL Te exhibits strong bulk photovoltaic effect (BPVE), being greater than that of GeS, a polar system with the largest BPVE found so far. Although the shift current conductivities of bulk and 2D Se are comparable, the shift current conductivities of TL Te are five times larger than those of bulk Te. Finally, an analysis of the calculated electronic band structures indicates that the strong NLO responses of 2D Se and Te materials are primarily derived from their low-dimensional structures with high anisotropy, directional covalent bonding, lone-pair electrons, and relatively small band gaps. These findings provide a practical strategy to search for excellent NLO and BPVE materials.

description: In the current conceptualisations of Problem Based Learning and how we practice it, the students are expected to possess the necessary academic competencies in order to study through PBL. However, a desk research reveals that students in many cases don't have the necessary understanding or conceptual comprehension of disciplines such as problem formulation, analysis, exploration, literature review etc., which prevents them from unfolding an explorative approach to their professional practice. This article thus discusses Dewey's concepts of sequential inquiry processes to create new forms of learning designs to bolden further students ability to work problem-based. The article discusses through the development of iterative learning design how structured sequences of activities can provide a descriptive language to qualify a methodology for PBL. The study is based on Educational Design Research (EDR) as the overarching framework where the methods of Design thinking inform the design activities through iterative processes. Through a period of two years a total of 400 students at the education of ATCM, at University College of Northern Denmark has participated. The data collection included results from observation, reflective portfolios and sound recordings from the students' group work in combination with sketches, drawing and artefacts from the iterative design process.

description: The need to increase students interested in pursuing careers in science, technology, engineering, and mathematics (STEM) is growing. The current study delivers results of an Upward Bound program focused on advancing students’ interest toward STEM fields and careers. Project STEMulate, funded by the National Science Foundation’s ITEST program, used Problem-Based Learning (PBL) in challenging students to engage in solving hands-on, real-world authentic problems in their communities. Project STEMulate takes structured PBL one step further by collaborating with local STEM Industry Partners for contextual learning and STEM pipeline development. The results revealed a raised interest in STEM, and a correlation between: 1) students’ career interest and their science ability and motivation, and 2) their Science Self-Efficacy and PBL ratings associated with their interest in STEM careers. These results highlight the significant potential of PBL instructional strategies to increase students’ attitudes toward and interest in future STEM careers.

description: We present new HST optical imagery as well as new UV and IR spectroscopic data obtained with the Hubble and Spitzer Space Telescopes, respectively, of the halo planetary nebula DdDm-1. For the first time we present a resolved image of this object which indicates that the morphology of DdDm-1 can be described as two orthogonal elliptical components in the central part surrounded by an extended halo. The extent of the emission is somewhat larger than was previously reported in the literature. We combine the spectral data with our own previously published optical measurements to derive nebular abundances of He, C, N, O, Ne, Si, S, Cl, Ar, and Fe. Our abundance determinations include the use of the newly developed program ELSA for obtaining abundances directly from emission line strengths along with detailed photoionization models to render a robust set of abundances for this object. The metallicity, as gauged by oxygen, is found to be 0.46 dex below the solar value, confirming DdDm-1's status as a halo PN. In addition, we find that Si and Fe are markedly underabundant, suggesting their depletion onto dust. The very low (but uncertain) C/O ratio suggests that the chemistry of the nebula should be consistent with an oxygen-rich environment. We find that the sulfur abundance of DdDm-1 is only slightly below the value expected based upon the normal lockstep behavior between S and O observed in H II regions and blue compact galaxies. The central star effective temperature and luminosity are estimated to be 55,000 K and 1000 solar luminosities, respectively, implying an initial progenitor mass of <1 solar masses. Finally, we report on a new radial velocity determination from echelle observations.

description: The objective of this study is to evaluate consumer willingness to pay for a brand that guarantees peaches produced by integrated pest management techniques. Contingent evaluation has been applied to a survey of consumers at the retail level. The econometric model of contingent evaluation shows the significant impact of socio- economic variables and consumer food style with respect to product characteristics. In other words, the variables affecting perception are more important that actual characteristics of product in determining its added value. Indeed, consumers are more willing to penalise unbranded peaches than to pay for a branded and guaranteed product. Consequently, a brand to guarantee food safety in peaches is not sufficient to increase added value but it is important in keeping market share.

description: This study contains several unique features that add to the literature documenting the health benefits of breastfeeding. The underlying theoretical framework for this study is the household economics model of Gary Becker. In particular, health production functions are specified and estimated. Data from the 1989 Brazilian National Health and Nutrition Survey are used to analyze the effects of breastfeeding on child morbidity (the absence of health). Binomial probit equations are estimated in which the dependent variable is whether the child required medical assistance during the previous two weeks for any of eight illness symptoms: fever, sore throat, loss of appetite, stomach ache, vomiting, diarrhea, respiratory problem, or a problem sleeping. The analysis is structured to be consistent with the WHO breastfeeding recommendations. For children 0-23 months, the impact of current breastfeeding on the need for medical care is analyzed and for infants 0-5 months, the effect of exclusive breastfeeding. Although the focus is on the impact of breastfeeding, the analysis is multivariate. Other possible determinants, which if excluded could bias the results, are included as additional explanatory variables. Several of the explanatory variables, including breastfeeding, are appropriately treated as endogenously determined and estimated with instrumental variables. Many studies end with a discussion of the econometric results. In this paper, the results of the probit analysis are used to simulate the possible reduction in the need for medical care if all children in Brazil were breastfed according to the WHO recommendations.
The response of sands under partially drained states with emphasis on liquefaction
Creators: name: Eliadorani, Ali Akbar
Publisher: name: University of British Columbia
Year: 2009

description: The occurrence of liquefaction and instability in saturated sands has been investigated under small departures from the undrained condition. Volumetric deformations are inevitable in field problems on account of the spatial variations in excess pore pressures generated during the earthquake shaking and their subsequent dissipation after, considered together with the relatively high permeability of sands. The departures from the undrained mode were simulated in the laboratory by loading sand under the strain path control, that simulated, not only zero, but small finite amount of controlled volumetric deformations. It is shown that the undrained state of loading normally assumed during earthquake shaking may not represent the most damaging scenario with regard to instability and liquefaction for certain initial density and stress states. At a given initial stress state, the denser sand may become susceptible to liquefaction and prone to instability if rendered partially drained as opposed to when it is completely undrained. For a given density, this potential for liquefaction and instability increases, both with increase in confining stress and static shear. The zone of contractive deformation in stress space where strains associated with strain softening on triggering of liquefaction occur gets enlarged substantially when small expansive volumetric deformations occur. The loose sand, that is liquefiable when undrained, may sustain this vulnerability, although to a lesser degree, even when compressive volumetric strains occur. Criteria for the occurrence of liquefaction and instability to occur under partially drained states have been developed, based on the known behavior of sand in undrained and fully drained conventional (constant confining stress) shear. The effects of the initial state variables - density, confining stress and static shear on partially drained response are assessed both in the triaxial compression and extension modes of deformations, taking cognizance of the inherent anisotropic nature of water deposited sands. For a given initial state, the sand, if liquefiable when undrained, continues to be so over a substantial range of even compressive volumetric strains. Finally, the similarities and differences between the phenomenon of strain softening associated with liquefaction problems and the conditions for instability under constant shear stress are pointed out. The association of strain increment directions with stress and stress increment directions are also explored under partially drained states in the region of effective stress space that does not involve strain softening.
Mixed Membership Graph Clustering via Systematic Edge Query

description: This work considers clustering nodes of a largely incomplete graph. Under the problem setting, only a small amount of queries about the edges can be made, but the entire graph is not observable. This problem finds applications in large-scale data clustering using limited annotations, community detection under restricted survey resources, and graph topology inference under hidden/removed node interactions. Prior works tackled this problem from various perspectives, e.g., convex programming-based low-rank matrix completion and active query-based clique finding. Nonetheless, many existing methods are designed for estimating the single-cluster membership of the nodes, but nodes may often have mixed (i.e., multi-cluster) membership in practice. Some query and computational paradigms, e.g., the random query patterns and nuclear norm-based optimization advocated in the convex approaches, may give rise to scalability and implementation challenges. This work aims at learning mixed membership of nodes using queried edges. The proposed method is developed together with a systematic query principle that can be controlled and adjusted by the system designers to accommodate implementation challenges -- e.g., to avoid querying edges that are physically hard to acquire. Our framework also features a lightweight and scalable algorithm with membership learning guarantees. Real-data experiments on crowdclustering and community detection are used to showcase the effectiveness of our method.

Facilitating Reflection and Progression in PBL: A Content Analysis of Generic Competences in Formal PBL Curricula

Publisher: name: Journal of Problem Based Learning in Higher Education

description: This paper proposes a systematic approach to the analysis of the prevalence of generic competences in formal problem-based learning (PBL) curricula at higher education institutions and universities in which generic competences are an integral and integrated part of the curriculum, with a particular focus on how the generic competences are specified explicitly in the curriculum. A case study on the implementation of PBL competences at Aalborg University (AAU) shows, that the dialectic relationship between knowledge and practice is limited after the first semester, with the risk that both knowledge, skills, and competences related to PBL become tacit and thus might be less easily expressed and related to the development of a professional identity. Based on this we argue that revision of the formal curricula must support students with theoretical knowledge on PBL, project management, and group collaboration throughout the study to accommodate a greater variety in types of problems, projects, and complexity. This calls for further elaboration of ‘generic’ competence frameworks and points to challenges and potentials for near-future and next practice curriculum development particularly with attention to the concept of progression, thus providing a benchmark for future research assessing the integration of PBL competences in formal curricula.

description: Hybrid courses with a focus on practice-orientated education and self-guided learning phases are on the rise on the higher education sector. Disciplines in Life Sciences implicate a high degree of practical laboratory expertise. The University of Applied Sciences (UAS) in Vienna, Austria, has thus been endeavoured offering students a high qualitative education integrating hybrid courses based on PBL principles, which consist of on-site (including the transmission of necessary background and practical laboratory training) and off-site (including self-study phases) sessions. As practical laboratory units are central in those courses, the restrictive measures, including the transition to a complete online teaching format due to the first Covid-19-pandemic lock-down, had severe effects on the implementation and the quality of the curriculum. According to surveys made specifically to address this problematic situation, it can be concluded that on-site practical units are fundamental for certain disciplines such as Life Sciences.

description: The purpose of this brief analysis is to consider the potential points of contact between a program of "green support" and the existing commodity programs in U.S. agriculture. These points of contact may take the form of conflict, complementarity, or neutrality. We shall assume initially that green support is "added" to the programs as they exist in 1994. Five main commodity program areas are considered: A. Deficiency payments resulting from the loan rate/target price structure B. Acreage reduction programs (ARPs) operating in conjunction with A. C. Conservation compliance, sodbuster and swampbuster programs D. Conservation Reserve Program (CRP) and the Wetland Reserve Program (WRP) E. GATT obligations and "planting flexibility" as a form of decoupling The analysis has four main parts. First, the concept of "incentive compatibility" is explored as the basis of the analysis to follow. Second, the five main program areas noted above are considered in terms of their compatibility with a program of green support. Third is a discussion of what changes in the five program areas would make them more compatible with green support. Finally consideration is given to how the green support program itself might be designed.

description: The emergence and spreading of chirality on the early Earth is considered by studying a set of reaction-diffusion equations based on a polymerization model. It is found that effective mixing of the early oceans is necessary to reach the present homochiral state. The possibility of introducing mass extinctions and modifying the emergence rate of life is discussed.

description: An essential part of Problem-Based Learning (PBL) is the students’ groupwork. What happens in students’ group work when no tutor/facilitator is present is normally a hidden land. Thus, there is limited research on students’ interactional way of doing PBL, this study tries to amend this by looking at how students conduct group work without any tutor/facilitator present. In this study, our research question is: How do students negotiate disagreements in their decision-making regarding their problem construction, and which element(s) in the interaction establishes if the decision is made or not? With a focus on students’ interactional work, we used video-observation to gather data of a 3rd semester Engineering Group at Aalborg University, Denmark. Our findings indicate that the conversation's structure has a profound impact on whether a decision proposal is accepted. Thus, the individual’s ability to hold on to their position and answer questions towards one’s proposal determines if other group members follow your suggestion. The study provides knowledge to an under-researched area of PBL and recommends a focus on PBL students’ interactional work in relation to near future cases of PBL.

description: We propose the novel augmented Gaussian random field (AGRF), which is a universal framework incorporating the data of observable and derivatives of any order. Rigorous theory is established. We prove that under certain conditions, the observable and its derivatives of any order are governed by a single Gaussian random field, which is the aforementioned AGRF. As a corollary, the statement ``the derivative of a Gaussian process remains a Gaussian process'' is validated, since the derivative is represented by a part of the AGRF. Moreover, a computational method corresponding to the universal AGRF framework is constructed. Both noiseless and noisy scenarios are considered. Formulas of the posterior distributions are deduced in a nice closed form. A significant advantage of our computational method is that the universal AGRF framework provides a natural way to incorporate arbitrary order derivatives and deal with missing data. We use four numerical examples to demonstrate the effectiveness of the computational method. The numerical examples are composite function, damped harmonic oscillator, Korteweg-De Vries equation, and Burgers' equation.

description: The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causing coronavirus disease-2019 (COVID-19) likely has evolutionary origins in other animals than humans based on genetically related viruses existing in rhinolophid bats and pangolins. Similar to other animal coronaviruses, SARS-CoV-2 contains a functional furin cleavage site in its spike protein, which may broaden the SARS-CoV-2 host range and affect pathogenesis. Whether ongoing zoonotic infections are possible in addition to efficient human-to-human transmission remains unclear. In contrast, human-to-animal transmission can occur based on evidence provided from natural and experimental settings. Carnivores, including domestic cats, ferrets and minks, appear to be particularly susceptible to SARS-CoV-2 in contrast to poultry and other animals reared as livestock such as cattle and swine. Epidemiologic evidence supported by genomic sequencing corroborated mink-to-human transmission events in farm settings. Airborne transmission of SARS-CoV-2 between experimentally infected cats additionally substantiates the possibility of cat-to-human transmission. To evaluate the COVID-19 risk represented by domestic and farmed carnivores, experimental assessments should include surveillance and health assessment of domestic and farmed carnivores, characterization of the immune interplay between SARS-CoV-2 and carnivore coronaviruses, determination of the SARS-CoV-2 host range beyond carnivores and identification of human risk groups such as veterinarians and farm workers. Strategies to mitigate the risk of zoonotic SARS-CoV-2 infections may have to be developed in a One Health framework and non-pharmaceutical interventions may have to consider free-roaming animals and the animal farming industry.

description: At the end of 2000, the European Commission published its Water Framework Directive (WFD) in the Official Journal of the European Communities (2000/60/EC). This new legislation provides for achieving the sustainable management of water resources through its 26 articles that focus primarily on the improvement and protection of the quality of European water resources. The WFD adopts an integrated approach, based upon general principles deriving mainly from four disciplinary approaches, Geography; Ecology; Economics and Sociology. The new challenges posed to the people responsible for the management of water resources across the European Union include the "marrying" of existing national policies with the stipulations of the WFD. Research can support this transition by identifying compatibility and conflicts between legislative instruments, and by encouraging trans-national cooperative relationships. A relevant role of research is also foreseen in providing criteria and tools for conflict resolution by representing the goals of sustainable management in an objective and transparent way. The elaboration required for making planning decisions are increasing in number and complexity, requiring tools that help to organise and communicate the data that should be used to describe the decision context in terms of sustainability, in a holistic way by including environmental, economic and social information. These problems are being addressed by the MULINO Project, a 3-year research program aiming at producing a Decision Support System that will assist water managers in responding to the evolution of policies and management methodologies. The development of the system, which will be prepared in a software format, is being steered by a group of people from European water authorities. This steering committee is contributing to the policy analysis component of the research and to the software design which aims to be applicable in five different national contexts. This paper addresses the challenges and innovations that have been encountered in the second phase of research in which the first prototype of the software has been developed to operate in specific decision situations in each of MULINO's six case studies.

description: The tension between enterprise as a means and sustainability as an end is directly related to the tension between rights to exclude others from a stream of private benefits and rights to be included in streams of environmental improvements. Resolving this tension is necessary if we are to square the circle between sustainability and enterprise. I begin for perspective with a brief review of the enclosure of land, and the widely cited notion of the Tragedy of the Commons. I then consider the modern version of the debate, surrounding informatics and, more specifically, intellectual property in plant genomics. The last part of the discussion focuses on a synthesis in which the two faces of enclosure - to be excluded and to be included - are brought together with democratic theory to give "sustainable enterprise" coherence and meaning.

description: We discuss the fermion couplings in a four dimensional SU(2) linear moose model by allowing for direct couplings between the left-handed fermions on the boundary and the gauge fields in the internal sites. This is realized by means of a product of non linear $σ$-model scalar fields which, in the continuum limit, is equivalent to a Wilson line. The effect of these new non local couplings is a contribution to the $ε_3$ parameter which can be of opposite sign with respect to the one coming from the gauge fields along the string. Therefore, with some fine tuning, it is possible to satisfy the constraints from the electroweak data.

description: The concept of entanglement in systems where the particles are indistinguishable has been the subject of much recent interest and controversy. In this paper we study the notion of entanglement of particles introduced by Wiseman and Vaccaro [Phys. Rev. Lett. 91, 097902 (2003)] in several specific physical systems, including some that occur in condensed matter physics. The entanglement of particles is relevant when the identical particles are itinerant and so not distinguished by their position as in spin models. We show that entanglement of particles can behave differently to other approaches that have been used previously, such as entanglement of modes (occupation-number entanglement) and the entanglement in the two-spin reduced density matrix. We argue that the entanglement of particles is what could actually be measured in most experimental scenarios and thus its physical significance is clear. This suggests entanglement of particles may be useful in connecting theoretical and experimental studies of entanglement in condensed matter systems.
