Digital economy and green transformation of regional industries: New insights from sustainability.

Studying the impact of the digital economy on carbon emissions in the distribution industry is of great significance for realizing sustainable development goals and coping with climate change. This study finds that increasing the level of digital economy development can reduce the carbon emission intensity of the circulation industry through fixed-effects modeling. Moreover, the effect is different in different geographic regions, and the improvement of the digital economy development level in the east and central regions can significantly reduce the carbon emission intensity of the distribution industry. The digital economy can simultaneously reduce the carbon emission intensity of the circulation industry by reducing the degree of labor factor mismatch in the circulation industry and improving the regional green innovation capacity. Therefore, in order to promote the green development of the distribution industry, it is also necessary to make efforts to improve the construction of network infrastructure, accelerate the process of research and development and cultivation of green technology, and break down the barriers of cross-regional mobility of talents.

A comprehensive assessment tool of acute-phase rehabilitation is associated with clinical outcomes in patients after cardiovascular surgery.

Perme intensive care unit (ICU) mobility score is a comprehensive mobility assessment tool; however, its usefulness and validity for patients after cardiovascular surgery remain unclear. We investigated the association between the Perme Score and clinical outcomes after cardiovascular surgery. We retrospectively enrolled 249 consecutive patients admitted to the ICU after cardiac and/or major vascular surgery. The Perme Score contains categories on mental status, potential mobility barriers, muscle strength and mobility level and was assessed within 2days after surgery. The outcomes of physical recovery were the number of days until 100-m ambulation achievement and 6-min walk distance (6MWD) at hospital discharge. The endpoint was a composite outcome of all-cause mortality and/or all-cause unplanned readmission. We analyzed the associations of the Perme Score with physical recovery and the incidence of clinical events. After adjusting for clinical confounding factors, a higher Perme Score was an independent factor of earlier achievement of 100-m ambulation (hazard ratio: 1.039, 95% confidence interval [CI]: 1.012-1.066) and higher 6MWD (β: 0.293, P = .001). During the median follow-up period of 1.1years, we observed an incidence rate of 19.4/100 person-years. In the multivariate Poisson regression analysis, a higher Perme Score was significantly and independently associated with lower rates of all-cause death/readmission (incident rate ratio: 0.961, 95% CI: 0.930-0.992). The Perme Score within 2days after cardiovascular surgery was associated with physical recovery during hospitalization and clinical events after discharge. Thus, it may be useful for predicting clinical outcomes.

EmPATHs - A serious board game to raise awareness and empathy towards vulnerable-to-exclusion groups in mobility

IntroductionSocial inequalities are a day-to-day problem experienced by the most vulnerable populations. In mobility, a basic human need, these inequalities can translate into lower accessibility to basic needs and social exclusion. The mobility barriers and needs of vulnerable-to-exclusion (v2e) groups have been documented in the literature, however, issues on accessibility, empathy and awareness strategies and people's attitudes remain. Serious games —fun teaching tools— have been successfully applied in urban/transport planning and have also been used to increase empathy and prosocial behavior. Despite the application of serious games in multiple fields pertinent to this study, the pressing mobility and accessibility issues faced by vulnerable populations have not been addressed in any serious game to date. This study focuses on creating and evaluating a serious board game (EmPATHs) to raise awareness and empathy towards v2e groups among various stakeholders while being fun at the same time. MethodIn this case, the goal of the game is to reach as many destinations as possible by playing different v2e personas. The winner of the game is the player who has reached the most destinations at the end with different v2e personas. EmPATHs targets university students from mobility-related programs, the general public, practitioners and decision makers from related fields. The game was created following a four-step iterative design process involving four categories of participants' groups, namely, frequent board game players (gamers) and experts on accessibility, mobility justice, and serious games. The game's evaluation was based on the answers of 26 players and focused on characteristics of serious games and the main goal of the game. The evaluation methodology included close-ended questions to assign a score from 1 to 5 to the established criteria and open-ended questions to complement with the quantitative results. Results & conclusionsThe participants considered EmPATHs to be a fun (4.4/5 score) and engaging (4.5/5 score) game, with a medium difficulty level (2.5/5 score) and which does not evoke frustrating feelings (2.0/5 score). The participants acknowledged learning more in-depth about barriers of v2e people (4.5/5 score) and recognized the game's capacity to raise awareness (4.5/5 score). They also felt more likely to empathize with v2e groups after the game (4.5/5 score). Future applications of the game can be expected to be in teaching contexts, public mobility-related events, and workshops with stakeholders from the planning and designing field.

Emergence of deglobalized tourist segments: Trends, challenges, and future research directions

Tourism has historically been a means of promoting globalization, encouraging cultural exchange and economic integration through travel. However, the emerging deglobalization phenomenon presents a paradox by emphasizing disconnection, reduced economic interdependence, and an increase in nationalist sentiments. This research note examines the emergence of deglobalized tourist segments influenced by external barriers such as restricted global mobility and sociopsychological barriers, as well as internal delimitations like hyper-nationalism and tourists' preferences for destinations that reflect their cultural norms and lifestyles. As a result, a typology of four deglobalized tourist segments is proposed: The Unconstrained Explorer, The Unconstrained Conformist, The Constrained Explorer, and The Constrained Conformist. The research note examines the intricate relationship between tourism and deglobalization, offering scholarly perspectives and future trends on how these factors contribute to the evolving dynamics of deglobalized tourism.

Border controls and (im)mobilities: experiences from a public transport node

The Öresund Bridge between Sweden and Denmark was opened in 2000, allowing both road traffic and fast commuter trains to travel between Malmö and Copenhagen. Various agreements have long facilitated passport-free travel. However, at the end of 2015, temporary border controls were first introduced. This paper aims to provide a deeper understanding of portrayals in the news media and everyday mobility experiences relating to border controls, with a special focus on Hyllie Station in the city of Malmö, in southern Sweden. The article is based on a compilation of the way Hyllie Station has been depicted in the news media for a deeper contextual understanding combined with a public participation GIS dataset focusing on the safety and security experiences of public transport nodes. Hyllie station, border controls and the presence of security personnel are depicted in different ways and at different levels. The complexities of life are intensified due to the daily cross-border commute and extra time required by border controls. The issue of mobility justice is raised, and the interrelationship between power and mobility becomes more and more tangible. Hyllie is a traffic node wherein the barriers of mobility and immobility become blurred, and power is displayed on different levels.

Transformable Quadruped Wheelchairs Capable of Autonomous Stair Ascent and Descent.

Despite advancements in creating barrier-free environments, many buildings still have stairs, making accessibility a significant concern for wheelchair users, the majority of whom check for accessibility information before venturing out. This paper focuses on developing a transformable quadruped wheelchair to address the mobility challenges posed by stairs and steps for wheelchair users. The wheelchair, inspired by the Unitree B2 quadruped robot, combines wheels for flat surfaces and robotic legs for navigating stairs and is equipped with advanced sensors and force detectors to interact with its surroundings effectively. This research utilized reinforcement learning, specifically curriculum learning, to teach the wheelchair stair-climbing skills, with progressively increasing complexity in a simulated environment crafted in the Unity game engine. The experiments demonstrated high success rates in both stair ascent and descent, showcasing the wheelchair's potential in overcoming mobility barriers. However, the current model faces limitations in tackling various stair types, like spiral staircases, and requires further enhancements in safety and stability, particularly in the descending phase. The project illustrates a significant step towards enhancing mobility for wheelchair users, aiming to broaden their access to diverse environments. Continued improvements and testing are essential to ensure the wheelchair's adaptability and safety across different terrains and situations, underlining the ongoing commitment to technological innovation in aiding individuals with mobility impairments.

"I Go Outdoors for Activities Every Day": Go-Along With Seniors With Slow Walking Speeds to Explore Environmental Factors Influencing Mobility.

This study aims to: 1) Explore the mobility experiences of seniors with slow walking speeds (SSWS) in urban neighborhoods; and 2) Investigate their environmental barriers and supports. Go-along interviews were conducted with 36 SSWS residing in urban neighborhoods of Chongqing City, China. The mobility patterns and built environment factors influencing their mobility were revealed through cartographic analysis and thematic analysis. SSWS primarily focused their activities within a 400-meter radius of their homes. Built environment themes included topography, neighborhood services, sidewalks, seating, traffic safety, weather, greenery, and lighting. Significant mobility barriers included long stairs, steep slopes, fast-moving objects on sidewalks, road crossings, and fast traffic. Available handrails, nearby food-service places, ample seating, and greenery were identified as supportive factors for their mobility. This study stands out as the first to specifically examine the mobility of SSWS within the built environment. We suggest that SSWS should be taken into account when establishing a benchmark for general design frameworks. These improvements not only contribute to the mobility of slow walkers but also have positive impacts on the broader population.

A latent class analysis of public perceptions about shared mobility barriers and benefits

The United States faces urban issues like congestion and pollution due to heavy car dependency, with over 91% owning cars and 87% driving to work. In response to these challenges, various shared mobility solutions have been integrated into transportation systems, encompassing bike-sharing, e-scooter sharing, and ride-hailing, but have not seen widespread adoption. To this end, this study investigates the perception of these services in the context of benefits and barriers. A survey was conducted in Indianapolis, Indiana and distributed online, gathering 424 responses. Latent class analysis (LCA) was used to determine groups of individuals with similar perceptions. The LCA identified three classes regarding perceptions of shared mobility benefits, and three others in relation to barriers. Regarding benefits, the classes include “Casual observers of benefits,” predominantly comprising older, less active females; “Benefits proponents,” featuring a majority of young, well-educated, higher-income males who prioritize health; and “Non-believers in benefits,” primarily consisting of older individuals, often identifying as black, with lower incomes and less active commuting. In terms of barriers, the classes are “Indifferent about barriers,” mainly comprising younger, lower-income individuals; “Shared mobility bystanders,” primarily characterized by older individuals with infrequent work commutes; and “Barrier conscious,” mostly including younger, well-educated, racially diverse individuals with complex commuting patterns. In both the benefits and barriers categories, the largest classes consist of individuals with neutral perspectives on shared mobility, signifying that a substantial portion of the population has not fully embraced these services. The study recommends policies to promote shared mobility to this significant population segment.

PHOTH-graphene: a new 2D carbon allotrope with low barriers for Li-ion mobility

The continued interest in 2D carbon allotropes stems from their unique structural and electronic characteristics, which are crucial for diverse applications. This work theoretically introduces PHOTH-Graphene (PHOTH-G), a novel 2D planar carbon allotrope formed by 4-5-6-7-8 carbon rings. PHOTH-G emerges as a narrow band gap semiconducting material with low formation energy, demonstrating good stability under thermal and mechanical conditions. This material has slight mechanical anisotropy with Young modulus and Poisson ratios varying between 7.08-167.8 GPa and 0.21-0.96. PHOTH-G presents optical activity restricted to the visible range. Li atoms adsorbed on its surface have a migration barrier averaging 0.38 eV.

Charge Carrier Regulation for Efficient Blue Quantum-Dot Light-Emitting Diodes Via a High-Mobility Coplanar Cyclopentane[b]thiopyran Derivative.

The performance of blue quantum dot light-emitting diodes (QLEDs) is limited by unbalanced charge injection, resulting from insufficient holes caused by low mobility or significant energy barriers. Here, we introduce an angular-shaped heteroarene based on cyclopentane[b]thiopyran (C8-SS) to modify the hole transport layer poly-N-vinylcarbazole (PVK), in blue QLEDs. C8-SS exhibits high hole mobility and conductivity due to the π···π and S···π interactions. Introducing C8-SS to PVK significantly enhanced hole mobility, increasing it by 2 orders of magnitude from 2.44 × 10-6 to 1.73 × 10-4 cm2 V-1 s-1. Benefiting from high mobility and conductivity, PVK:C8-SS-based QLEDs exhibit a low turn-on voltage (Von) of 3.2 V. More importantly, the optimized QLEDs achieve a high peak power efficiency (PE) of 7.13 lm/W, which is 2.65 times that of the control QLEDs. The as-proposed interface engineering provides a novel and effective strategy for achieving high-performance blue QLEDs in low-energy consumption lighting applications.

Transformable Fire Barriers for Filling Openings (Overview)

The review of scientific and technical literature on the problem of ensuring fire safety of public and industrial buildings by dividing rooms into fire compartments using transformable fire barriers (TFB), as well as by protecting openings with transformable fire fillings is presented. The general classification of TFB is presented, the requirements for TFB are described, the use cases of various types of TFB and their design features are considered. Engineering solutions for transformable fire shelters, as well as mobile fire barriers, are presented. It has been established that the fire resistance limit of TFB is higher when used in combination with water irrigation, but the disadvantage of the system is the high consumption of coolant (from 0.12 liters/s of water per 1 linear meter of opening width), which, in addition to material costs, also has a destructive effect on finishing materials and building structures. A possible way to solve these problems is to use various fillers in the working cloth that emit inert or extinguishing gases, but this method needs additional verification in the form of modeling and physical experiments.

Land Security and Mobility Frictions

Abstract Frictions that impede the mobility of workers across occupations and space are a prominent feature of developing countries. We disentangle the role of insecure property rights from other labor-mobility frictions for the reallocation of labor from agriculture to nonagriculture and from rural to urban areas. We combine rich household and individual-level panel data from China and an equilibrium quantitative framework featuring sorting of workers across locations and occupations. We explicitly model the farming household and the endogenous decisions of who operates the family farm and who potentially migrates, capturing an additional channel of selection in the household. We find that land insecurity has substantial negative effects on agricultural productivity and structural change, raising the share of rural households operating farms by over 40 percentage points and depressing agricultural productivity by more than 20%. Comparatively, these quantitative effects are as large as those from all residual labor-mobility frictions. We measure a sharp reduction in overall labor-mobility barriers over 2004–2018 in the Chinese economy, all accounted for by improved land security, consistent with reforms covering rural land in China during the period.

Boon and burden: economic performance and future perspectives of the Venice flood protection system

Sea-level rise (SLR) and flooding are among the climate change stressors challenging human society in the twenty-first century. Many coastal areas and cities are implementing innovative solutions to mitigate flood risks and enhance resilience. Venice has recently developed a system of storm surge mobile barriers, known as the MoSE (Modulo Sperimentale Elettromeccanico or Experimental Electromechanical Module). This study aims to investigate the economic viability of MoSE operations in light of the potential future evolution of SLR. To conduct a cost-benefit analysis, a system dynamics model is utilised to assess the impact of MoSE operations on economic and residential activities of Venice and its port. Simulations are conducted until the end of the century, considering two SLR scenarios. The results suggest that the economic benefits largely outweigh the combined costs of investment and foregone port revenues resulting from the MoSE closures. Nevertheless, the increasing number of closures due to SLR seriously challenges the viability of the infrastructure in the medium to long term. Even more importantly, very frequent closures will have serious impacts on the quality of the lagoon ecosystem. These findings suggest a revision and stronger integration of the city’s safeguarding strategies, including the increase of the MoSE closure level officially set at 110 cm, and other coordinated interventions, such as sewer system consolidation.

Uncovering suppressed travel: A scoping review of surveys measuring unmet transportation need

Unrealized travel and its associated activity participation is included in many overlapping concepts in the literature—unmet need, latent demand, suppressed travel, and forgone travel. In this scoping review, we focus on suppressed travel, which we define as travel, and associated activity participation, that is unrealized due to transportation-related social exclusion and associated mobility barriers. We review how researchers have measured suppressed travel using surveys, identifying which populations are studied (who), which destinations are considered (where), how questions are structured (how), which barriers are identified as causes of suppressed travel (why), and to what extent questions address suppressed desires and mobility horizons (what). We also assess study quality. We conducted a search using sets of keywords relating to equity, transportation, and surveys. We identified 3,522 unique abstracts from Web of Science and Scopus published since the year 2000. Two undergraduate reviewers independently screened the abstracts with author oversight. The authors conducted full-text reviews of 533 remaining studies. Of these, 158 survived to data extraction, and 19 of those could ultimately be included in this analysis. We find strong evidence of travel suppression among older adults and people with disabilities. Insufficient transit service and dependency on others for rides are identified as primary causes. Among the general population, unrealized travel is greater for leisure and eating out trips, while populations experiencing TRSE face travel suppression for work, education, and other essential trips. We identify gaps in populations and causes studied and conclude with recommendations on how to advance knowledge in this area.

Configuration of a telerehabilitation system to deliver a comprehensive aphasia therapy program via telerehabilitation (TeleCHAT): A human-centred design approach

ABSTRACT The delivery of Intensive Comprehensive Aphasia Programs (ICAPs) via telerehabilitation is a potential solution to the ongoing geographical, transport, and mobility barriers that people with aphasia (PWA) face in accessing this service model. To ensure the ICAP retains its evidence-based elements, configuration of the telerehabilitation system requires consideration of user and therapy task requirements. The human-centred design (HCD) process incorporates user and task considerations when developing technological systems. Therefore, the aim of this study was to use the HCD process to translate the Comprehensive High-dose Aphasia Therapy (CHAT) program for delivery via telerehabilitation (TeleCHAT). Methods The HCD translation process used consisted of five iterative stages. Relevant literature was reviewed, and speech-language pathologists (SLPs) experienced in delivering ICAPs were consulted to understand the therapy context. Researchers gathered therapy task and user requirements of PWA, support people (SP) and SLPs to engage in therapy. Technology that met user and therapy task requirements were identified and a preliminary technology configuration was tested in a simulated environment. The finalised system was tested in a pilot trial of TeleCHAT with a cohort of four PWA, two SPs, and two SLPs. Feedback and technical and user issues were collated from users and analysed to inform improvements to the TeleCHAT configuration and protocol. Results User and therapy task requirements to deliver TeleCHAT were identified with consideration of communication and participation supports for PWA. The configured technology system comprised of Zoom© as the videoconferencing platform of choice, and additional critical technical functions including screen and audio sharing of therapy content, and multi-point interaction using remote control and annotation tools. Simulation testing and a pilot trial of the configuration confirmed system operability and identified modifications to optimise functioning. Conclusion The HCD framework was used to successfully configure an optimal technology system for the delivery of TeleCHAT. The HCD framework can be used by clinicians to identify patient needs and configure optimal telerehabilitation systems for delivery of complex interventions.

Mobile barrier mechanisms for Na+-coupled symport in an MFS sugar transporter

While many 3D structures of cation-coupled transporters have been determined, the mechanistic details governing the obligatory coupling and functional regulations still remain elusive. The bacterial melibiose transporter (MelB) is a prototype of major facilitator superfamily transporters. With a conformation-selective nanobody, we determined a low-sugar affinity inward-facing Na+-bound cryoEM structure. The available outward-facing sugar-bound structures showed that the N- and C-terminal residues of the inner barrier contribute to the sugar selectivity. The inward-open conformation shows that the sugar selectivity pocket is also broken when the inner barrier is broken. Isothermal titration calorimetry measurements revealed that this inward-facing conformation trapped by this nanobody exhibited a greatly decreased sugar-binding affinity, suggesting the mechanisms for substrate intracellular release and accumulation. While the inner/outer barrier shift directly regulates the sugar-binding affinity, it has little or no effect on the cation binding, which is supported by molecular dynamics simulations. Furthermore, the hydron/deuterium exchange mass spectrometry analyses allowed us to identify dynamic regions; some regions are involved in the functionally important inner barrier-specific salt-bridge network, which indicates their critical roles in the barrier switching mechanisms for transport. These complementary results provided structural and dynamic insights into the mobile barrier mechanism for cation-coupled symport.

Review on Lightweight Mobile Flood Wall Barrier: Way Forward for Malaysia

Flooding is a persisting challenge in Malaysia. Combating flood risk has become a main priority for sustainable development in this country. The application of sophisticated engineering in hard structure approaches and flood control systems are often incongruous to the public. Therefore, there is a need to integrate the soft engineering approaches and the best practises of flood management to mitigate flood risk. There is also a need to integrate the concept of sustainable development into its planning policies towards flood hazard reduction. Mobile flood protection measures are useful as an alternative solution in flood protection and mitigation purposes. Mobile protective systems can be used for temporarily increasing the height of permanent flood protection structures during extreme events and can be utilised as emergency measure against flooding in unprotected low-lying areas. As the available mobile systems differ in the type of material, method of installation and available protection height, a description of their features, and potential application were examined including their respective opportunities and drawbacks. This article presents a review on different types of lightweight mobile flood wall barrier (MFWB) that were implemented to cope with floods in Malaysia with examples of application in other countries such as United Kingdom, Slovakia, and Netherlands. The MFWB products are reviewed and compared to each other according to the types, characteristics, mechanisms, drawbacks and how these measures are integrated into spatial planning. Based on the findings, several suggestions are given on how to improve the flood risk management in flood-prone areas and way forward for Malaysia.
