The Impact

Due to the limited safety of pedestrians, as well as the ability to direct their movement according to the established infrastructure, the analysis of the impact of factors consistent with the concept of push/pull, seems justified and useful. The aim of the article is to try to apply the concepts of push / pull in terms of the impact of logistics infrastructure on the nature of pedestrian traffic. The components of the logistics infrastructure related to the movement of the population are public roads, roads of cities and other settlements, departmental (technological) roads, roads in private areas, providing access to external and internal vehicles and passengers. The nature of pedestrian traffic is determined by the decision-making process of a certain person when moving along a certain route. It is proved that the form and result of this process are influenced by psychological and social mechanisms. It is established the main psychological and social characteristics of pedestrian traffic: maintaining personal space, as a result of which people prefer to «move for», keeping a distance of ten or several tens of centimeters; avoidance of direct impact of discomfort (psychological and physical), ie «movement from» different intensities, depending on the scale of the projected threat; minimization of efforts that cause «movement against» the shortest way; conformism (tendency to succumb to group behavior and attitude to novelty, different levels of which determine belonging to groups of innovators, early followers, early majority, late majority and conservatives); cultural norms (modification of behavior based on the influence of learned principles). The article presents models of simple situations of pedestrian traffic, which in practice demonstrate the influence of determinants of push/pull factors. It is substantiated that simulation of pedestrian traffic allows to increase its safety. Pedestrian safety issues are particularly important due to the high risk of accidents and their impact on other transport processes. However, the current state of knowledge about the determinants of the push / pull system does not yet allow such a free and comprehensive modeling.

Abstract Nanomaterials are sure to take an important part in shaping the 21st century. Nevertheless, their increasing application in many fields of the industry also turns attention to the impact on health and environment. To achieve this goal, it is necessary to fully understand the influence of nanoparticles on the environment and the relevant safety issues. The aim of the present review is to characterise the current state of regulation and legislation of nanomaterials, as well as the factors of safety assessment and their toxicity.

Podkarpackie Voivodeship is one of the regions of Poland in which the number of agritourism entities is very high. Therefore tourism plays a significant role in its development strategy. The aim of the paper is to identify the current state of agritourism and the changes that have occurred in the region in the years 2000–2016. Specific objectives are to determine the distribution of agritourism farms and their offer, together with a comprehensive analysis of the environmental and socio-economic factors, as well as the impact of the Slovak-Ukrainian border. The report was developed on the statistical materials from the Polish Central Statistical Office, Podkarpackie Agricultural Advisory Centre in Boguchwała and data collected from municipalities and district offices that is published on their websites, as well as through interviews with 100 owners of agritourism farms in the Podkarpackie Voivodeship. The research has shown, on the one hand, the decline in the number of farms in the region and, on the other hand, the increase in the diversity of the tourist offer of these entities. Distribution of agritourism farms is closely linked to the attractiveness of natural environment and quality of secondary tourism resources. Traditional agritourism has not yet fully used its countryside, as well as cross-border advantages of its location.

This chapter looks at the challenges, opportunities, and tensions facing the equitable development of artificial intelligence (AI) in the MENA region in the aftermath of the Arab Spring. While diverse in their natural and human resource endowments, countries of the region share a commonality in the predominance of a youthful population amid complex political and economic contexts. Rampant unemployment—especially among a growing young population—together with informality, gender, and digital inequalities, will likely shape the impact of AI technologies, especially in the region’s labor-abundant resource-poor countries. The chapter then analyzes issues related to data, legislative environment, infrastructure, and human resources as key inputs to AI technologies which in their current state may exacerbate existing inequalities. Ultimately, the promise for AI technologies for inclusion and helping mitigate inequalities lies in harnessing grounds-up youth entrepreneurship and innovation initiatives driven by data and AI, with a few hopeful signs coming from national policies.

AbstractIt is well known that the surface topography of a part can affect its mechanical performance, which is typical in additive manufacturing. In this context, we report about the surface modification of additive manufactured components made of Titanium 64 (Ti64) and Scalmalloy®, using a pulsed laser, with the aim of reducing their surface roughness. In our experiments, a nanosecond-pulsed infrared laser source with variable pulse durations between 8 and 200 ns was applied. The impact of varying a large number of parameters on the surface quality of the smoothed areas was investigated. The results demonstrated a reduction of surface roughness Sa by more than 80% for Titanium 64 and by 65% for Scalmalloy® samples. This allows to extend the applicability of additive manufactured components beyond the current state of the art and break new ground for the application in various industrial applications such as in aerospace.

The Impact

Land use changes influence the water balance and often increase surface runoff. The resulting impacts on river flow, water level, and flood should be identified beforehand in the phase of spatial planning. In two consecutive papers, we develop a model-based decision support system for quantifying the hydrological and stream hydraulic impacts of land use changes. Part 1 presents the semi-automatic set-up of physically based hydrological and hydraulic models on the basis of geodata analysis for the current state. Appropriate hydrological model parameters for ungauged catchments are derived by a transfer from a calibrated model. In the regarded lowland river basins, parameters of surface and groundwater inflow turned out to be particularly important. While the calibration delivers very good to good model results for flow (Evol =2.4%, R = 0.84, NSE = 0.84), the model performance is good to satisfactory (Evol = −9.6%, R = 0.88, NSE = 0.59) in a different river system parametrized with the transfer procedure. After transferring the concept to a larger area with various small rivers, the current state is analyzed by running simulations based on statistical rainfall scenarios. Results include watercourse section-specific capacities and excess volumes in case of flooding. The developed approach can relatively quickly generate physically reliable and spatially high-resolution results. Part 2 builds on the data generated in part 1 and presents the subsequent approach to assess hydrologic/hydrodynamic impacts of potential land use changes.

The Impact

Advances in neuroimaging of the preterm infant have enhanced the ability to detect brain injury. This added information has been a blessing and a curse. Neuroimaging, particularly with magnetic resonance imaging, has provided greater insight into the patterns of injury and specific vulnerabilities. It has also provided a better understanding of the microscopic and functional impacts of subtle and significant injuries. While the ability to detect injury is important and irresistible, the evidence for how these injuries link to specific long-term outcomes is less clear. In addition, the impact on parents can be profound. This narrative summary will review the history and current state of brain imaging, focusing on magnetic resonance imaging in the preterm population and the current state of the evidence for how these patterns relate to long-term outcomes.

While many facets of loneliness have been explored, research examining the efficacy of loneliness interventions has been overlooked among young adults. The study of loneliness among young adults has become increasingly important considering the current state of isolation and stay-at-home orders issued to prevent the spread of COVID-19. Preliminary reports suggest an increase in loneliness as a result of the current health pandemic, especially among young adults, who have reported feeling lonelier than any other age group. Such findings warrant the study of ways to help reduce loneliness among young adults. The current study examined the efficacy of strategies that might be used to help young adults manage feelings of loneliness. Two hundred and seventy-eight young adults completed the study. Participants read one of four messages: mindfulness, social cognitions, coping behaviors, or a control. Participants in the mindfulness condition felt better equipped to manage future instances of loneliness and held better attitudes toward this intervention. The current research helps to advance understanding of effective ways of helping young adults cope with loneliness.

The Impact

The coronavirus disease (COVID-19) continues to spread globally. While social distancing has attracted attention as a measure to prevent the spread of infection, some occupations find it difficult to implement. Therefore, this study aims to investigate the relationship between work characteristics and social distancing using data available on O*NET, an occupational information site. A total of eight factors were extracted by performing an exploratory factor analysis: work conditions, supervisory work, information processing, response to aggression, specialization, autonomy, interaction outside the organization, and interdependence. A multiple regression analysis showed that interdependence, response to aggression, and interaction outside the organization, which are categorized as ”social characteristics,” and information processing and specialization, which are categorized as “knowledge characteristics,” were associated with physical proximity. Furthermore, we added customer, which represents contact with the customer, and remote working, which represents a small amount of outdoor activity, to our multiple regression model, and confirmed that they increased the explanatory power of the model. This suggests that those who work under interdependence, face aggression, and engage in outside activities, and/or have frequent contact with customers, little interaction outside the organization, and little information processing will have the most difficulty in maintaining social distancing.

Abstract There is evidence from the development and humanitarian sectors that purposeful engagement of women can increase the impact of development. We conducted a literature review to examine whether this is also evident in conservation and natural resource management. The following themes emerged from our review: existing societal and cultural norms affect and generally limit how women can engage in conservation and natural resource management; women interact differently with the environment than men, so if they are excluded, their knowledge and perspectives on particular resources may not be considered in conservation actions; and there is often a lack of resources or dedicated effort by conservation or natural resource management programmes to understand and address the barriers that prevent women's engagement. Although there was evidence of a positive relationship between the engagement of women and environmental outcomes, some studies showed that positive conservation outcomes do not necessarily benefit women, and when women are not considered, conservation activities can perpetuate existing inequities. We conclude that although the importance of integrating gender into conservation is acknowledged in the literature, there is a need to examine how women can be meaningfully engaged in conservation. This must go beyond treating women as a homogenous group, to consider intersectionality including race, ethnicity, age, religion, poverty and disability. In addition, conservation and natural resource management institutions need to address the inclusion of women in their own staff and programmes.

Abstract Background The aim of this study is to evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on breastfeeding women and to identify predictors of maternal mental health and coping. Methods Mothers aged ≥ 18 years with a breast-fed infant ≤ 18 months of age during the COVID-19 pandemic in Beijing, China, completed a questionnaire. Descriptive analysis of lockdown consequences was performed and predictors of these outcomes were examined using stepwise linear regression. Results Of 2233 participants, 29.9%, 20.0% and 34.7% felt down, lonely, and worried, respectively, during the lockdown; however, 85.3% felt able to cope. Poorer maternal mental health was predicted by maternal (younger age, higher education) and infant (older age, lower gestation) characteristics, and social circumstances (husband unemployed or working from home, receiving advice from family, having enough space for the baby, living close to a park or green space). Conversely, better maternal mental health was predicted by higher income, employment requiring higher qualifications, more personal space at home, shopping or walking > once/week and lack of impact of COVID-19 on job or income. Mothers with higher education, more bedrooms, fair division of household chores and attending an online mother and baby group > once/week reported better coping. Conclusion The findings highlight maternal characteristics and circumstances that predict poorer mental health and reduced coping which could be used to target interventions in any future public health emergencies requiring social restrictions.
