Sharing Economy and Fast Fashion (Sustainability and virtual consumer behavior: A review and research agenda)

The main objective of this work, through a literature review, is to contextualize the importance of fashion consumer behavior towards a more sustainable economy, emphasizing the sharing economy as an alternative to fast fashion through virtual networks, and therefore also highlights the use that consumers make of new technologies (social networks, mobile applications, or collaborative platforms). The specific objectives are none other than showing the need to contribute to the reduction of pollution, damage to the environment and the overconsumption of natural resources (water, energy, or materials) involved in the manufacture of clothing. All this linked to consumer behavior, innovation, electronic commerce, the sharing economy, and the entrepreneurship of the social and solidarity economy. It is for this reason that this work is approached from a perspective that can help to promote the exchange of fashion, examining the antecedents of the intention of consumers to participate in virtual fashion networks. The consolidation of the sharing economy in the fashion industry could offer social, economic, and environmental benefits, so this research also wants to highlight the convenience of identifying and analyzing the different beliefs of people with similar behaviors using this type of virtual fashion networks and platforms, and that, due to the confinement of COVID-19, seems to have increased exponentially. The value that is provided is to establish a common framework for discussion, within which the research has been carried out, since there is still much to analyze about consumer behavior in this context, and therefore the future of research in this area must bring together social, economic, and technological research to provide a more holistic understanding. It is desirable that sustainability and the need for more sustainable consumption are a motivating influence for future research on the sharing economy related to fast fashion and virtual consumer behavior.
Preload Dependency of 2D Right Ventricle Speckle Tracking Echocardiography Parameters in Healthy Volunteers: A Prospective Pilot Study

(1) Background: Right ventricular (RV) strain parameters derived from the analysis of the tricuspid annular displacement (TAD) are emergent two-dimensional speckle tracking echocardiography (2D-STE) parameter used for the quantitative assessment of RV systolic function. Few data are available regarding 2D-STE parameters and their dependency on RV preload. Our aim was to evaluate the effect of an acute change in RV preload on 2D-STE parameters in healthy volunteers. (2) Methods: Acute modification of RV preload was performed by a fluid challenge (FC): an infusion of 500 mL of 0.9% sodium chloride was given over 5 min in supine position. Preload dependency (responder group) was confirmed by a stroke volume increase of at least 10% measured by echocardiography. (3) Results: Among 32 healthy volunteers, 19 (59%) subjects were classified as non-responders and 13 (41%) as responders. In the responder group, the tricuspid annular plane systolic excursion (TAPSE) significantly increased (20 (20–23.5) mm to 24 (20.5–26.5) mm; p = 0.018), while RV strain parameters significantly decreased after FC: −23.5 ((−22.3)–(−27.3))% to −25 ((−24)–(29.6))%; p = 0.03) for RV free wall longitudinal strain and −22.8 ((−20.4)–(−30.7))% to −23.7 ((−21.2)–(−27))%; p = 0.02) for RV four-chamber longitudinal strain. 2D-STE parameters derived from the TAD analysis were not influenced by the FC (all p > 0.05). (4) Conclusions: In young, healthy volunteers, RV strain parameters and TAPSE are preload dependent, while TAD parameters were not. The loading conditions must be accounted for when evaluating RV systolic function by 2D-STE parameters.
Post-stroke Anxiety Among Patients in Jordan: A Multihospital Study

This study aimed to assess the prevalence, correlates, and significant associated factors of anxiety among patients with stroke. A cross-sectional, correlation design was utilized. The Hospital Anxiety and Depression scale was used to detect and assess the severity of anxiety and depression among mentally well patients at general hospital settings. Among the 226 patients with stroke, 45.6% had clinically significant levels of anxiety to be considered as a definite case. Having a short duration since the stroke onset, being a definite case of depression, being unable to perform self-care activities, having an insufficient monthly income, and having visual problems due to stroke were the significantly associated factors. The high prevalence of anxiety among patients with stroke highlights the need for interventions of early detection and management to enhance recovery. Patients who have any of the significant traits predicted post-stroke anxiety required special attention.
The effect of concession period design on completion risk management of BOT projects

The design of concession period for build–operate–transfer (BOT) projects is crucial to financial viability and completion risk management. A systematic analysis shows that concession period design involves the design of concession period structure, the determination of the concession period length and incentive schemes. The concession period may have a single‐period structure or a two‐period structure, its length may be fixed or variable, and it may be combined with incentive schemes. Different designs reflect different risk control strategies for completion time overruns. The single‐period concession structure requires the project company to assume completion risk, while the two‐period concession structure could, to some extent, reduce the completion risk exposure to the project company, depending on the incentive schemes. Through Monte Carlo simulation, this paper evaluates the mean net present value (NPV), variance and NPV‐at‐risk of different concession period structures so that both the government and the concessionaires can understand their risk exposure and rewards. The paper then analyses the influence of project characteristics on concession period design to evaluate the feasibility of the design. It is concluded that a well‐designed concession period structure can create a ‘win–win’ solution for both project promoter and the host government.
A simplified evaluation of protection distance in areal spectrum sharing

: This paper focuses on a spectrum sharing cellular system primarily used by noncellular, stand-alone wireless systems. Geographically deployed base stations (BSs) that cover the service area to continuously provide spectrum sharing act as a secondary system, where the sharing condition is provided to the total interference power at the primary system. In this case, how much transmission power from each BS is allowed on the shared spectrum? By applying the propagation model originally used to evaluate cellular systems, this paper numerically and theoretically reveals the relation between the protection distance (PD) and allowable transmission power.
Pharmacokinetics of Pullulan–Dexamethasone Conjugates in Retinal Drug Delivery

The treatment of retinal diseases by intravitreal injections requires frequent administration unless drug delivery systems with long retention and controlled release are used. In this work, we focused on pullulan (≈67 kDa) conjugates of dexamethasone as therapeutic systems for intravitreal administration. The pullulan–dexamethasone conjugates self-assemble into negatively charged nanoparticles (average size 326 ± 29 nm). Intravitreal injections of pullulan and pullulan–dexamethasone were safe in mouse, rat and rabbit eyes. Fluorescently labeled pullulan particles showed prolonged retention in the vitreous and they were almost completely eliminated via aqueous humor outflow. Pullulan conjugates also distributed to the retina via Müller glial cells when tested in ex vivo retina explants and in vivo. Pharmacokinetic simulations showed that pullulan–dexamethasone conjugates may release free and active dexamethasone in the vitreous humor for over 16 days, even though a large fraction of dexamethasone may be eliminated from the eye as bound pullulan–dexamethasone. We conclude that pullulan based drug conjugates are promising intravitreal drug delivery systems as they may reduce injection frequency and deliver drugs into the retinal cells.
Increased structural covariance in brain regions for number processing and memory in children with developmental dyscalculia

Developmental dyscalculia (DD) is a developmental learning disability associated with deficits in processing numerical and mathematical information. Several studies demonstrated functional network alterations in DD. Yet, there are no studies, which examined the structural network integrity in DD. We compared whole‐brain maps of volume based structural covariance between 19 (4 males) children with DD and 18 (4 males) typically developing children. We found elevated structural covariance in the DD group between the anterior intraparietal sulcus to the middle temporal and frontal gyrus (p < 0.05, corrected). A hippocampus subfield analysis showed higher structural covariance in the DD group for area CA3 to the parahippocampal and calcarine sulcus, angular gyrus and anterior part of the intraparietal sulcus as well as to the lingual gyrus. Lower structural covariance in this group was seen for the subiculum to orbitofrontal gyrus, anterior insula and middle frontal gyrus. In contrast, the primary motor cortex (control region) revealed no difference in structural covariance between groups. Our results extend functional magnetic resonance studies by revealing abnormal gray matter integrity in children with DD. These findings thus indicate that the pathophysiology of DD is mediated by both structural and functional abnormalities in a network involved in number processing and memory function.
ARMin III --arm therapy exoskeleton with an ergonomic shoulder actuation

Rehabilitation robots have become important tools in stroke rehabilitation. Compared to manual arm training, robot-supported training can be more intensive, of longer duration and more repetitive. Therefore, robots have the potential to improve the rehabilitation process in stroke patients. Whereas a majority of previous work in upper limb rehabilitation robotics has focused on end-effector-based robots, a shift towards exoskeleton robots is taking place because they offer a better guidance of the human arm, especially for movements with a large range of motion. However, the implementation of an exoskeleton device introduces the challenge of reproducing the motion of the human shoulder, which is one of the most complex joints of the body. Thus, this paper starts with describing a simplified model of the human shoulder. On the basis of that model, a new ergonomic shoulder actuation principle that provides motion of the humerus head is proposed, and its implementation in the ARMin III arm therapy robot is described. The focus lies on the mechanics and actuation principle. The ARMin III robot provides three actuated degrees of freedom for the shoulder and one for the elbow joint. An additional module provides actuated lower arm pro/supination and wrist flexion/extension. Five ARMin III devices have been manufactured and they are currently undergoing clinical evaluation in hospitals in Switzerland and in the United States.
Psychological Approaches for the Integrative Care of Chronic Low Back Pain: A Systematic Review and Metanalysis

Chronic low back pain (CLBP) is the most common cause of disability worldwide, affecting about 12% to 30% of the adult population. Psychological factors play an important role in the experience of pain, and may be predictive of pain persistence, disability, and long-term sick leave. The aim of this meta-analysis was to identify and to describe the most common psychological approaches used to treat patients who suffer from CLBP. A systematic search was performed on PubMed/MEDLINE and Cochrane Central. Overall, 16 studies with a total of 1058 patients were included in the analysis. Our results suggest that cognitive behavioral therapy (CBT) and mindfulness-based stress reduction (MBSR) interventions are both associated with an improvement in terms of pain intensity and quality of life when singularly compared to usual care. Disability also improved in both groups when compared to usual care. Significant differences in fear-avoidance beliefs were noted in the CBT group compared to usual care. Therefore, psychological factors are related to and influence CLBP. It is crucial to develop curative approaches that take these variables into account. Our findings suggest that CBT and MBSR modify pain-related outcomes and that they could be implemented in clinical practice.
Development of Micro Enterprises through the Assistance of Business Actors: Case Study on Micro Business Assistance in Bintan Regency, Riau Islands, Indonesia

Micro, Small and Medium Enterprises (MSMEs) are one of the pillars of the nation's economy. Therefore various strategies have been pursued to develop them so that they are able to contribute to welfare, provide employment opportunities and alleviate poverty. One of these strategies, which is implemented by the government, is the availability of assistance for MSME actors through the Integrated Business Service Center (PLUT) program and Small and Medium Enterprise Cooperatives (KUKM). By using qualitative research methods and literature studies, this study aims to determine the extent of the participation of these facilitators in the development of MSMEs in Bintan Regency, especially micro-enterprises and examine the impact of PLUT and KUKM assistance on MSME development in Bintan Regency. This research is expected to be a reference in efforts to develop MSMEs through mentoring and open opportunities for further research on the appropriate and optimal pattern of MSME assistance in developing MSMEs.
Investigating Influences on the Pb Pseudo‐Isochron Using Three‐Dimensional Mantle Convection Models With a Continental Reservoir

For mid‐ocean ridge basalts and ocean island basalts, measurements of Pb isotope ratios show broad linear correlations with a certain degree of scatter. In 207Pb/204Pb—206Pb/204Pb space, the best fit line defines a pseudo‐isochron age (τPb) of ∼1.9 Gyr. Previous modeling suggests a relative change in the behaviors of U and Pb between 2.25 and 2.5 Ga, resulting in net recycling of HIMU (high U/Pb) material in the latter part of Earth's history, to explain the observed τPb. However, simulations in which fractionation is controlled by a single set of partition coefficients throughout the model runs fail to reproduce τPb and the observed scatter in Pb isotope ratios. We build on these models with 3D mantle convection simulations including parameterizations for melting, U recycling from the continents and preferential removal of Pb from subducted oceanic crust. We find that both U recycling after the great oxygenation event and Pb extraction after the onset of plate tectonics, are required in order to fit the observed gradient and scatter of both the 207Pb/204Pb—206Pb/204Pb and 208Pb/204Pb—206Pb/204Pb arrays. Unlike much previous work, our model does not require accumulations of subducted oceanic crust to persist at the core‐mantle boundary for long periods of time in order to match geochemical observations.
Lean Principles Applied to Extended Value Stream Mapping To Achieve a Costs Savings in the North American Automotive Industry

In 2007, Toyota surpassed General Motors as the world's largest automaker. This signaled the beginning of a very challenging time for N O1ih America's automakers. Amidst a worsening global economy and slumping consumer demand, the SUV and pick-up truck sectors found themselves in deep crisis. Sales plummeted between 2007 and 2008. It became imperative for these automakers to provide better value for consumers by implementing costs savings. This paper deals with one such cost savings that was achieved through the application oflean principles to an extended value stream. Value stream maps were used as the instrument to study and identify improvement 0ppoliunities. The lean improvement methodology also relied on value stream maps to model the proposed improved versions ofthe extended value stream. By passing on part of the savings to the consumer, the automaker was able to provide better value to its customers. As predicted by the literature, the lean principles for improving 2
A NEW APPROACH FOR ENERGY RECOVERY AND TURBOCOMPOUNDING SYSTEMS FOR HIGH ALTITUDE FLIGHT WITH COMMON RAIL DIESEL ENGINES

This paper introduces an original method for the preliminary calculations and the turbomatching of a dual stage high altitude turbocompounding system. This method is conceived to use modified automotive commercial turbochargers along with electric motor/generators. The method used is innovative and uses only the data commonly available from the manufacturer. In the example described herein, full power and throttle control are achieved up to 10, 000m (32, 000ft). The engine is a Common Rail Direct Injection Diesel engine derived from the automotive market. The calculation method and the problems connected are widely discussed. For this application turbocompunding is a good option that partially compensates the unavoidable increase in TOW (Take Off Weight). In drones that have relatively large batteries, the ERS (Energy Recovery System) does not increase the air vehicle mass.
The Influence of Organisational Justice on Job Satisfaction: Evidence from an Emerging Nation

With employee turnover becoming a significant managerial problem, the purpose of this paper is to examine the effect of organisational justice on employees' job satisfaction. This study is based on a questionnaire survey conducted in Saudi Arabia. Based on a model developed for this study, the paper uses empirical research to determine the relationship between distributional, procedural, and interactional justices on employees' job satisfaction. Findings of this study reveal that distributive and interactional dimensions of organisational justice have influence on the employees' job satisfaction in the Kingdom. The limitation of sample size and generalisation of results for the entire Kingdom of Saudi Arabia, although sample has been confined to the eastern region are some limitations of this study. This study makes a valuable contribution given the fact that there is a dearth of empirical studies of this nature undertaken in the Middle East region.
Hydrogen sulfide inhibits human T‐cell leukemia virus type‐1 (HTLV‐1) protein expression via regulation of ATG4B

Hydrogen sulfide (H2S) is a redox gasotransmitter. It has been shown that H2S has a key role in host antiviral defense by inhibiting interleukin production and S‐sulfhydrating Keap1 lead to Nrf2/ARE pathway activation. However, it is yet unclear whether H2S can play an antiviral role by regulating autophagy. In this study, we found that exogenous H2S decreased the expression of human T‐cell leukemia virus type‐1 (HTLV‐1) protein and HTLV‐1 induced autophagosomes accumulation. Transmission electron microscope assays indicated that autophagosomes accumulation decreased after H2S administration. HTLV‐1‐transformed T‐cell lines had a high level of CSE (H2S endogenous enzyme) which could be induced in Hela by HTLV‐1 infection. Immunoblot demonstrated that overexpression of CSE inhibited HTLV‐1 protein expression and autophagy. And we got the opposite after CSE knockdown. Meanwhile, H2S could not restrain the autophagy when ATG4B had a mutant at its site of 89. In a word, these results suggested that H2S modulated HTLV‐1 protein expression via ATG4B. Therefore, our findings suggested a new mechanism by which H2S defended against virus infection.
Design and Performance Analysis of a 1550nm Al 0.09 Ga 0.38 In 0.53 As/InP MQW VCSEL by Varying Injection Current

The Vertical-Cavity Surface-Emitting Laser (VCSEL) is becoming a key device in high-speed optical local-area networks (LANs) and even wide-area networks (WANs). This device is also enabling ultra parallel data transfer in equipment and computer systems. In this work, the performance characteristics of a designed AlGaInAs/InP based 1550nm multiple quantum well (MQW) VCSEL have been obtained through computations. The obtained characteristics have been analyzed for obtaining better performance. For achieving a superior performance, the concentrations of AlGaInAs QW material have been chosen using the results of other research works. The material gain of a compressive strained Al0.09Ga0. 38In0.53As/InP MQW VCSEL has been theoretically computed. Using the peak material gain obtained from this computation the performance characteristics of the designed VCSEL have been obtained. At 300K, the threshold current of the VCSEL has been obtained as 0.61mA. A maximum output power of 2.24mW has been obtained for this designed VCSEL at 6.1mA injection current. Corresponding to the frequency modulation, the maximum resonance frequency has been obtained as 7.7GHz at 6.1mA injection current which indicates high speed performance of the designed VCSEL. By varying injection current the characteristics of designed VCSEL have also been obtained.
Facemask Use During High Intensity Interval Exercise in Temperate and Hot Environments

Exercise routines are effective interventions to reduce risk of chronic disease. Health concerns regarding mask use may lead individuals to adopt a less active lifestyle. Knowledge of perceptual and physiological responses with mask use during exercise may lead individuals to adapt training routines and maintain the health benefits of exercise. Objective: The purpose of this study was to investigate the effects of surgical mask use during high intensity interval exercise (HIIE) on physiological and perceptual responses in hot and temperate environments. Methods: In a randomized fashion, 10 healthy participants completed two HIIE sessions in a 36°C hot (HUE-HOT) and two HIIE sessions in a 23°C temperate environment (HIIE-TEMP) while wearing (MASK) and not wearing a surgical mask (CON). Results: No differences in physiological variables were found between MASK and CON during HIIE. An increase in perceived dyspnea and average RPE was found comparing MASK and CON. Interaction effects showed the greatest changes in perceived dyspnea and average RPE occurred in the HIIE-HOT/MASK condition. Conclusion: Wearing a surgical mask during HIIE increases the perception of dyspnea and exertion with the greatest effect occurring in hot environments.
Large Eddy Simulation of Unsteady Flow in a Mixed Flow Pump Guide Vane

In order to investigate the characteristics of unsteady flow in a mixed flow pump guide vane under the small flow conditions, several indicator points in a mixed flow pump guide vane was set, the three-dimensional unsteady turbulence numerical value of the mixed flow pump which is in the whole flow field will be calculated by means of the large eddy simulation (LES), sub-grid scale model and sliding mesh technology. The experimental results suggest that the large eddy simulation can estimate the positive slope characteristic of head & capacity curve. And the calculation results show that the pressure fluctuation coefficients of the middle section in guide vane inlet will decrease firstly and then increase. In guide vane outlet, the pressure fluctuation coefficients of section will be approximately axially symmetrical distribution. The pressure fluctuation minimum of section in guide vane inlet is above the middle location of the guide vane suction surface, and the pressure fluctuation minimum of section in which located the middle and outlet of guide vane. When it is under the small flow operating condition, the eddy scale of guide vane is larger, and the pressure fluctuation of the channel in guide vane being cyclical fluctuations obviously which leads to the area of eddy expanding to the whole channel from the suction side. The middle of the guide vane suction surface of the minimum amplitude pressure fluctuation to which the vortex core of eddy scale whose direction of fluids rotation is the same to impeller in the guide vane adhere.
