Creators: name: Kanwar, Richa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The purpose of this study was to identify the factors and decisions that affect the implementation of Contextual Inquiry, and explain which factors act as facilitators contributing towards the success of the project and which factors act as barriers hindering the success of the project. To determine these factors this study observed the application of Contextual Inquiry in a real-world project where it was applied to understand the reasons behind healthcare provider burnout. Using methods such as interviews, surveys and group discussions with the implementation team of the real-world project, this study was able to identify 18 Facilitators, 9 Barriers, and 3 Critical Decisions that impact the outcome of a Contextual Inquiry implementation in a healthcare setting.

description: This study investigates faculty members’ attitudes towards adopting technology-enhanced learning tools in their teaching practice as an emergency response to the latest pandemic. It concerns faculty preparedness and response to the imposed suspension of face-to-face classes and the integration of the emergency remote teaching that took place in early March 2020. Underpinned by transformative learning theory, the study collected data from a questionnaire and one-to-one interviews with 13 faculty members teaching at Qatar’s Education City. The study provides insight into faculty’s abilities to adapt their teaching approaches to ensure curriculum continuity in emergency situations. Faculty members were also able to revamp their curricula to provide a variety of learning materials that engage their students, rethink their assessment techniques and tools, and find time to connect with the students, check on their progress as well as their wellbeing. This study contributes to the transformative learning theory by proposing a reversed model that was experienced during the pandemic. Furthermore, although the study is situated in Qatar, it has resonances beyond the Qatari context as it emphasises the need for continuous professional development opportunities for faculty members to acquire, maintain, and improve their online teaching skills for a national online learning strategy. Finally, this study contributes to the field of technology-enhanced learning by rethinking its applicability in light of and beyond the pandemic.
Liminal Space: Identifying Bisexual Materials in Public Library Catalogs
Creators: name: Morris, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: This study aggregates and analyzes the bisexuality-related subject headings used by three database types: folksonomies, public library catalogs, and a private subscription database. One folksonomy, one subscription database, and five public libraries (one from each region in the United States) were sampled to triangulate existing subject headings and how discoverable they are by database users. The folksonomy, which described only bisexual materials, was used to create a recommended reading list. These books were then searched for in the public library catalogs and the subscription database for sexuality-related subject headings and other descriptive metadata. Though each database contained at least some of the suggested materials, none correctly described each item; some were not described with bisexuality-related terminology at all, while some were misidentified as solely heterosexual or homosexual.

description: A general class of mean field games are considered where the governing dynamics are controlled diffusions in $\mathbb{R}^d$. The optimization criterion is the long time average of a running cost function. Under various sets of hypotheses, we establish the existence of mean field game solutions. We also study the long time behavior of mean field game solutions associated with the finite horizon problem, and under the assumption of geometric ergodicity for the dynamics, we show that these converge to the ergodic mean field game solution as the horizon tends to infinity. Lastly, we study the associated $N$-player games, show existence of Nash equilibria, and establish the convergence of the solutions associated to Nash equilibria of the game to a mean field game solution as $N\to\infty$.

Finite Gyroradius Corrections in the Theory of Perpendicular Diffusion, 1. Suppressed Velocity Diffusion

description: A fundamental problem in plasma physics, space science, and astrophysics is the transport of energetic particles interacting with stochastic magnetic fields. In particular the motion of particles across a large scale magnetic field is difficult to describe analytically. However, progress has been achieved in the recent years due to the development of the unified non-linear transport theory which can be used to describe magnetic field line diffusion as well as perpendicular diffusion of energetic particles. The latter theory agrees very well with different independently performed test-particle simulations. However, the theory is still based on different approximations and assumptions. In the current article we extend the theory by taking into account the finite gyroradius of the particle motion and calculate corrections in different asymptotic limits. We consider different turbulence models as examples such as the slab model, noisy slab turbulence, and the two-dimensional model. Whereas there are no finite gyroradius corrections for slab turbulence, the perpendicular diffusion coefficient is reduced in the other two cases. The matter investigated in this article is also related to the parameter a^2 occurring in non-linear diffusion theories.

A Study of the Use of Unrestricted Health Information in Digitized Medical Archival Collections
Creators: name: Almond, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: There are significant concerns for those working in medical archives, health sciences collections, and history of medicine collections regarding the provision of online access to medical records. Archival control is required to de-identify all records containing protected health information (PHI) as defined by the Health Information Portability and Accountability Act (HIPAA), but 2013 alterations to the privacy rule included a change in the definition of PHI that excludes information about individuals deceased for more than fifty years. This exploratory study investigates how archivists in medical and health collections approach the use of this newly available unrestricted health information (UHI) in digital environments. Interviewed participants address how they conceptualize UHI, view the practice of digitization, impose standards on their practice, and manage access to collections online. Findings suggest that archivists do not perceive significant differences between online access to PHI and UHI online, exerting archival control by de-identifying all online data.

Ten reasons why a thermalized system cannot be described by a many-particle wave function
Creators: name: Drossel, Barbara
Publisher: name: arXiv
Year: 2015
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: It is widely believed that the underlying reality behind statistical mechanics is a deterministic and unitary time evolution of a many-particle wave function, even though this is in conflict with the irreversible, stochastic nature of statistical mechanics. The usual attempts to resolve this conflict for instance by appealing to decoherence or eigenstate thermalization are riddled with problems. This paper considers theoretical physics of thermalized systems as it is done in practise and shows that all approaches to thermalized systems presuppose in some form limits to linear superposition and deterministic time evolution. These considerations include, among others, the classical limit, extensivity, the concepts of entropy and equilibrium, and symmetry breaking in phase transitions and quantum measurement. As a conclusion, the paper argues that the irreversibility and stochasticity of statistical mechanics should be taken as a true property of nature. It follows that a gas of a macroscopic number $N$ of atoms in thermal equilibrium is best represented by a collection of $N$ wave packets of a size of the order of the thermal de Broglie wave length, which behave quantum mechanically below this scale but classically sufficiently far beyond this scale. In particular, these wave packets must localize again after scattering events, which requires stochasticity and indicates a connection to the measurement process.

description: The last mile presents the logistics chain’s lowest efficiency and highest cost. Thus, the bicycle emerges as a promising alternative in the rising efforts to advance urban logistics sustainability. This research aims to identify factors for successful last-mile cycle logistics implementation in a comparative study of two cities from the Global South and North. Berlin and Sao Paulo cases were analyzed to outline the cycle logistics ecosystem and to derive learnings. Twelve semi-structured interviews were conducted with key stakeholders of each city to gather their perceptions of cycle logistics challenges, social acceptance, green premium, good practices, and main agents, enabling the analysis of each city’s ecosystem and a comparative analysis between them. The systematization of challenges, good practices, and stakeholders’ maps highlighted four aspects for successful cycle logistics implementation: clear identification of demands and challenges; acknowledgment and communication of learnings; advancement of practices addressing local challenges; cooperation between diverse key stakeholders. Ultimately, two relevant takeaways are that cycle logistics has a specific application scope and it is an alternative among many options that, together with the comprehension of local context, is crucial for the cycle logistics development. Still, experiences and exchanges with other cities may leverage implementation success.

description: Dispersing graphene nanosheets in polymer-derived ceramics (PDCs) has become a promising route to produce exceptional mechanical and functional properties. To reveal the complex nanodomain structures of graphene–PDC composites, a novel reduced graphene oxide aerogel embedded silicon oxycarbide (RGOA-SiOC) nanocomposite was fabricated bottom-up using a 3D reduced graphene oxide aerogel as a skeleton followed by infiltration of a ceramic precursor and high-temperature pyrolysis. The reduced graphene oxide played a critical role in not only the form of the free carbon phase but also the distribution of SiOxC4−x structural units in SiOC. Long-ordered and continuous graphene layers were then embedded into the amorphous SiOC phase. The oxygen-rich SiOxC4−x units were more prone to forming than carbon-rich SiOxC4−x units in SiOC after the introduction of reduced graphene oxide, which we attributed to the bonding of Si atoms in SiOC with O atoms in reduced graphene oxide during the pyrolysis process.

description: Speculations about the origin of SARS-CoV-2 have catapulted bats into the spotlight of scientific and societal attention, with unforeseen consequences for bat conservation. In two global surveys with bat experts before and during the COVID-19 pandemic, we assessed their (i) threat perceptions, emotions towards bats and social trust in decision makers and (ii) the predictive potential of emotions, social trust and socio-demographic variables on threat perceptions. We also discuss (iii) the potential influence of the pandemic on threat perception and antecedents (emotions and social trust). We received 495 responses from 65 countries in September 2019 and 320 responses in June 2020 from 77 countries. We identified three major threat categories (indirect, direct and prejudice). Comparing threat perception, emotions and social trust between both surveys, we found that indirect threats (e.g., habitat modification) were considered as crucial, yet less so during the pandemic. During the pandemic, experts rated indirect threats lower and the perceived threat through prejudice (e.g., myths) higher than before the pandemic. During the pandemic, bat experts also expressed more compassion and sadness related to bats and trust in researchers and NGOs, but less trust in laypeople than before the pandemic. Emotions were particularly important predictors for threats through prejudice besides social trust. Socio-demographic variables (e.g., cultural and professional background) had predictive potential predominantly for direct threats (e.g., hunting and trade, wind turbines) and threats through prejudice. Our study highlights the role of emotions and social trust on threat perception among bat experts who remained relatively invisible during the pandemic despite their key role for bat conservation. More importantly, we echo previous calls to be more attentive to ecological grief also within the scientific community; especially as discussions around zoonotic spillover with valued study animals intensify.

description: The COVID-19 pandemic marked a global disruption of unprecedented scale which was closely associated with human mobility. Since mobility acts as a facilitator for spreading the virus, individuals were forced to reconsider their respective behaviors. Despite numerous studies having detected behavioral changes during the first lockdown period (spring 2020), there is a lack of longitudinal perspectives that can provide insights into the intra-pandemic dynamics and potential long-term effects. This article investigates COVID-19-induced mobility-behavioral transformations by analyzing travel patterns of Berlin residents during a 20-month pandemic period and comparing them to the pre-pandemic situation. Based on quantitative analysis of almost 800,000 recorded trips, our longitudinal examination revealed individuals having reduced average monthly travel distances by ∼20%, trip frequencies by ∼11%, and having switched to individual modes. Public transportation has suffered a continual regression, with trip frequencies experiencing a relative long-term reduction of ∼50%, and a respective decrease of traveled distances by ∼43%. In contrast, the bicycle (rather than the car) was the central beneficiary, indicated by bicycle-related trip frequencies experiencing a relative long-term increase of ∼53%, and travel distances increasing by ∼117%. Comparing behavioral responses to three pandemic waves, our analysis revealed each wave to have created unique response patterns, which show a gradual softening of individuals’ mobility related self-restrictions. Our findings contribute to retracing and quantifying individuals’ changing mobility behaviors induced by the pandemic, and to detecting possible long-term effects that may constitute a “new normal” of an entirely altered urban mobility landscape.
Capturing a Moment: The Practices and Ethics of Social Media Archiving
Creators: name: Breed, Miana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The rise in popularity and ubiquity of social media has led to an increase in archival collection of social media data. Collecting and preserving this data is a relatively new challenge and creates technical and staffing barriers for archives. In an exploratory study of the practices and ethics of social media archiving, thirty-eight archivists responded to a Qualtrics survey about their institutional practices, their opinions of the ethical responsibilities of archives toward social media users, and the questions they still have about social media archiving. The survey revealed that only half the participating archival institutions collect social media. A majority of institutions collect data from blogs, Facebook, and YouTube, and most report using some form of API collecting tool. After reviewing the results of the survey, some current social media collecting policies, and a national web archiving survey, findings were framed using the ethical concerns voiced by the Documenting the Now project. The study suggests that archivists in general have the desire to use donor agreements and other permission forms for social media archiving, but the tools to contact all potential users are not yet available. This study forms an initial argument for further research into the best practices and ethical responsibilities of social media archiving.

description: This study aimed to explore the difference in user engagement with a search assistance tool in different positions on a SERP. A usability study with eye-tracker was conducted in a lab environment. Overall, there were 12 subjects participated in this study, each of them was asked to perform two tasks on a search system with a search assistance tool placed in two positions. Qualitative data collected from the retrospective interview and quantitative data gathered from questionnaires, eye-tracking system, and custom log system were analyzed to investigate the position effect. The results in this study showed that the search assistance tool placed in the middle is easier to get noticed while people are more likely to pay attention to it and use it when the search assistance tool is placed on the right side of the page. Also, the source authority and the information foraging theories like Camouflage Links, Banner Blindness have impacts on the use of the search assistance tool.

description: The paper provides energy system-wide estimates of the potential and impacts of final energy demand reductions based on behavioral changes in different sectors. Behavioral changes are for example adjusting thermostats or replacing business flights with telemeetings. By reducing demand, behavioral changes are a potentially decisive but seldomly considered factor to support the transformation towards a decarbonized energy system. Therefore, this paper addresses the following question: What is the potential of behavioral changes and what are the impacts on the supply side of a 100% renewable energy system? For this purpose, an extensive literature review is conducted to obtain estimates for the effects of different behavioral changes on final energy demand in Germany. The impact of these changes on the supply side and system costs is quantified using a bottom-up planning model of a renewable energy system. Results indicate that final energy could be reduced by up to 20.5% and as a result, renewable capacity reductions between 13.6% to 30.6% are conceivable. The greatest potential for behavioral changes was identified in the heating sector.

description: The metal budgets in some white dwarf (WD) atmospheres reveal that volatile-rich circumstellar bodies must both exist in extrasolar systems and survive the giant branch phases of stellar evolution. The resulting behaviour of these active asteroids or comets which orbit WDs is not well-understood, but may be be strongly influenced by sublimation due to stellar radiation. Here we develop a model, generally applicable to any extrasolar system with a main sequence or WD star, that traces sublimation-induced orbital element changes in approximately km-sized extrasolar minor planets and comets traveling within hundreds of au. We derive evolution equations on orbital timescales and for arbitrarily steep power-law sublimation dependencies on distance, and place our model in a Solar system context. We also demonstrate the importance of coupling sublimation and general relativity, and the orbital consequences of outgassing in arbitrary directions. We prove that nongravitational accelerations alone cannot result in orbit crossing with the WD disruption radius, but may shrink or expand the orbit by up to several au after a single pericentre passage, potentially affecting subsequent interactions with remnant debris and planets. Our analysis suggests that extant planets must exist in polluted WD systems.

description: The advent of the new generation of X-ray telescopes yielded a significant step forward in our understanding of ionised absorption generated in the accretion discs of X-ray binaries. It has become evident that these relatively weak and narrow absorption features, sporadically present in the X-ray spectra of some systems, are actually the signature of equatorial outflows, which might carry away more matter than that being accreted. Therefore, they play a major role in the accretion phenomenon. These outflows (or ionised atmospheres) are ubiquitous during the softer states but absent during the power-law dominated, hard states, suggesting a strong link with the state of the inner accretion disc, presence of the radio-jet and the properties of the central source. Here, we discuss the current understanding of this field.

description: Software product line has emerged as an attractive phenomenon within organizations dealing with software development process. It involves assembly of products from existing core assets, commonly known as components, and continuous growth in the core assets as production proceeds. Organizations trying to incorporate the concept of software product line to reduce development time and cost require certain rules to be followed for successful development and management, they also require a direct procedure to evaluate the current maturity level of the process. In this work certain rules for developing and managing a software product line are put forward. Additionally, a fuzzy logic based software product line process assessment tool (SPLPAT) has been designed and implemented on the basis of developed rules for software product line process assessment. SPLPAT can be used to assess the process maturity level of software product line, and it provides an opportunity to handle imprecision and uncertainty present in software process variables. Four case studies were conducted to validate the framework, and results show that SPLPAT provides a direct mechanism to evaluate current software product line process maturity level within an organization. The results of the developed software product line process assessment approach were compared with the existing CMM-level of the organization in order to evaluate the reliability of the presented approach and to find out how effectively an organization can execute software product line process when it has already achieved a certain CMM level.
Crowdfunding in Libraries: An Analysis of Library Crowdfunding Project Data

Year: 2019

description: Crowdfunding is one of the newest strategies libraries are using to connect with donors. While the past several years have produced a consistent trickle of reports about libraries using crowdfunding to extend traditional fundraising activities, research thus far has largely been constrained to case studies and surveys. By studying 174 library and archive projects on Kickstarter and Indiegogo, this research determined that library and archive crowdfunding campaigns raise more money on average and are more likely to successfully meet their funding goals than typical Kickstarter campaigns. Additional findings regarding types of projects crowdfunded, types of libraries crowdfunding, and amount of campaigns launched over time are discussed. This study hopes to support library practitioners in judging the feasibility of crowdfunding as a practical fundraising strategy and determining the contexts in which crowdfunding is most likely to be successful.

description: Silicon photonic two-dimensional grating couplers for C- and O-band dual-polarization coherent transceivers are analyzed with respect to their polarization splitting/combining performance. Due to scattered light in the grating's plane, a linear cross-polarization results. The latter is responsible for a limited polarization split ratio and a polarizations' non-orthogonality. The impact of these two quantities is evaluated by system-level simulations with regard to OSNR penalties in coherent systems. For both C- and O-band, a design modification for reduced penalties is proposed.

description: The production of high-resolution digital terrain models (DTMs) based on images is often hampered by the lack of appropriate stereo observations. Here, we propose a deep learning-based reconstruction of pixel-resolution DTMs from Lunar Reconnaissance Orbiter (LRO) single-view narrow angle camera (NAC) images, constrained by Selenological and Engineering Explorer and LRO LOLA Elevation Models (SLDEM). The procedure is carried out for a set of adjacent images, and the mosaicking of a contiguous large-area DTM is demonstrated. The approach is applied to the CE-3 and CE-4 landing sites, involving six multiple coverage and eight adjacent NAC L/R image pairs, respectively. For the DTM reconstruction, we use an improved convolutional neural network architecture with a weighted sum loss function involving three loss terms. We demonstrate that our method is robust and can deal with images acquired under varying illumination conditions. The DTM mosaic (1.5 m pixel size) covering the CE-4 landing area (72.8 × 30.3 km) is without apparent seams between the individual image boundaries and consistent with the SLDEM (60 m pixel size) in terms of overall elevation, trend, and scale, but is showing considerably more morphologic detail.

description: We present NuSTAR observations of the powerful radio galaxy Cygnus A, focusing on the central absorbed active galactic nucleus (AGN). Cygnus A is embedded in a cool-core galaxy cluster, and hence we also examine archival XMM-Newton data to facilitate the decomposition of the spectrum into the AGN and intracluster medium (ICM) components. NuSTAR gives a source-dominated spectrum of the AGN out to >70keV. In gross terms, the NuSTAR spectrum of the AGN has the form of a power law (Gamma~1.6-1.7) absorbed by a neutral column density of N_H~1.6x10^23 cm^-2. However, we also detect curvature in the hard (>10keV) spectrum resulting from reflection by Compton-thick matter out of our line-of-sight to the X-ray source. Compton reflection, possibly from the outer accretion disk or obscuring torus, is required even permitting a high-energy cutoff in the continuum source; the limit on the cutoff energy is E_cut>111keV (90% confidence). Interestingly, the absorbed power-law plus reflection model leaves residuals suggesting the absorption/emission from a fast (15,000-26,000km/s), high column-density (N_W>3x10^23 cm^-2), highly ionized (xi~2,500 erg cm/s) wind. A second, even faster ionized wind component is also suggested by these data. We show that the ionized wind likely carries a significant mass and momentum flux, and may carry sufficient kinetic energy to exercise feedback on the host galaxy. If confirmed, the simultaneous presence of a strong wind and powerful jets in Cygnus A demonstrates that feedback from radio-jets and sub-relativistic winds are not mutually exclusive phases of AGN activity but can occur simultaneously.

description: FLOTANT project public deliverable. The purpose of this document is to introduce the Socio-economic Cost of Energy (SCOE) model and present the results for the FLOTANT project. The model is based on UEDIN’s work on previous projects and uses various estimates and assumptions to provide a holistic analysis of the economic value that shall be returned to the Scottish and Canary Islands' economy on deployment of the FLOTANT project. This report starts off with an introduction to the adopted methodology along with the assumptions and inputs used for the preliminary analysis. It then goes on to discuss the results produced from the model and concludes the findings of the analysis.

description: The zero sets of harmonic polynomials play a crucial role in the study of the free boundary regularity problem for harmonic measure. In order to understand the fine structure of these free boundaries a detailed study of the singular points of these zero sets is required. In this paper we study how "degree $k$ points" sit inside zero sets of harmonic polynomials in $\mathbb R^n$ of degree $d$ (for all $n\geq 2$ and $1\leq k\leq d$) and inside sets that admit arbitrarily good local approximations by zero sets of harmonic polynomials. We obtain a general structure theorem for the latter type of sets, including sharp Hausdorff and Minkowski dimension estimates on the singular set of "degree $k$ points" ($k\geq 2$) without proving uniqueness of blowups or aid of PDE methods such as monotonicity formulas. In addition, we show that in the presence of a certain topological separation condition, the sharp dimension estimates improve and depend on the parity of $k$. An application is given to the two-phase free boundary regularity problem for harmonic measure below the continuous threshold introduced by Kenig and Toro.

description: In einer Spurensuche nach verlorenen und verdrängten Orten queerer Stadtkultur kommen Protagonist*innen zu Wort, die das Leben, die politische Situation von LGBTQIA+-Communities und (Stadt-)Räume gestaltet und die queere Geschichtsschreibung Berlins geprägt haben. Sie sprechen exemplarisch über die Diskothek Lipstick, die Deutsche Oper als schwuler Treffpunkt, den Frauenbuchladen Lilith, das feministische Archiv FFBIZ und die Klappe im Preußenpark. Diese Oral Histories stellen die Orte den Stimmen der Protagonist*innen in collagenhaften Audio-Features gegenüber. Sie erzählen von vergessenen Möglichkeitsräumen und Sehnsuchtsorten, von Räumen queerer Identifikation und Fürsorge, von Protest, Widerstand und Gleichberechtigung. Dabei wird eines klar: Neben Idealismus und dem Drang nach Selbstermächtigung sind queere Raumpraktiken geprägt von Unsicherheiten und Instabilität. Die Hörbilder werden von Vignetten begleitet, die Schlaglichter auf mögliche Ursachen von Prozessen der Instabilität werfen und die Erfahrungen von Protagonist*innen der 1970er- bis 1990er-Jahre mit aktuellen urbanen Transformationsprozessen in Zusammenhang stellen.
C# Traceability System

description: Traceability information is a valuable asset that software development teams can leverage to minimise their risk during production and maintenance of software projects. When maintainers are added to a software project post-production, they have to learn the system from scratch and understand its dynamics before they can begin making appropriate modifications to the source code. The system outlined in this paper extracts traceability information directly from the source code of C# projects, and presents it in such a way that it can be easily used to understand the logic and validate changes to the system.
Asynchronous Networks and Event Driven Dynamics

description: Real-world networks in technology, engineering and biology often exhibit dynamics that cannot be adequately reproduced using network models given by smooth dynamical systems and a fixed network topology. Asynchronous networks give a theoretical and conceptual framework for the study of network dynamics where nodes can evolve independently of one another, be constrained, stop, and later restart, and where the interaction between different components of the network may depend on time, state, and stochastic effects. This framework is sufficiently general to encompass a wide range of applications ranging from engineering to neuroscience. Typically, dynamics is piecewise smooth and there are relationships with Filippov systems. In the first part of the paper, we give examples of asynchronous networks, and describe the basic formalism and structure. In the second part, we make the notion of a functional asynchronous network rigorous, discuss the phenomenon of dynamical locks, and present a foundational result on the spatiotemporal factorization of the dynamics for a large class of functional asynchronous networks.
Development of a Course Recommender System for Students
Creators: name: Yadav, Harish

description: Students at the university have an information need to find the courses of their interest. The current university registration portals do not fulfill this information need completely. We have proposed the development of a recommender system which can take a course name and based on the description of that course recommend other courses to students. The recommended course list could help save time and effort for students registering for courses. The proposed system was trained with sample data collected from the course catalog of the University of North Carolina at Chapel Hill. We tested the recommender system with different courses as input and evaluated the resulting recommended courses.

description: Regarding climate change and energy resource problems, mobility transition is essential to shift from private fossil cars to sustainable modes in both the passenger and freight sectors. One of the reasons that citizens depend on their private cars is using this mode for carrying parcels, shopping, and transporting children. However, new electrized mobility modes like electric cargo bikes (e-cargo bikes) can provide mobility services to decrease citizens' car dependency. Recently, their share in the modal splits of cities has been increasing through technological advancement, infrastructure development, and government support in some countries. This paper aims to provide a comprehensive and international review of the role of e-cargo bikes in urban transportation. This paper reviewed and synthesized international studies in the field of e-cargo in terms of typology, technical parameters, users' characteristics, and readiness of cities for this emerging transport mode. Moreover, the barriers and driving factors for developing e-cargo bikes were analyzed and compared in terms of social, economic, environmental parameters, and regulations in different countries.
