Re-signifying HIV through exercise: from death sentence stigma to healthy self-perception

ABSTRACT Despite HIV being considered a chronic disease and the benefits that exercise interventions can bring to HIV-infected patients, the application of physical activity is currently low. Some qualitative studies have been conducted; however, it is currently little known about the meaning of the experience of exercising in people with HIV. This hermeneutic research used 21 in-depth, semi-structured interviews with patients with this condition. The analysis was based on a grounded Theory methodology, which is theoretically supported by symbolic interactionism. It was possible to advance in re-signifying HIV from a social stigma context. This process, through exercise and social, family and medical support, comes from the breaking of individual and collective perception paradigms. Particularly, exercise changes the perspective from a HIV-infected person on the verge of death to a healthy, active and functional individual with personal goals. Thus, by contributing to functionality and health recovery, exercise re-signifies life. Moreover, commitment to physical activity goals is influenced by inner tensions that can hinder or encourage this habit and demand further research. HIV infection shifts from being a death sentence to a healthy self-perception beyond the diagnosis.

The study addresses the analysis of the ethnic “Other” images in the stereotypes of Russians, utilizing data from internet searches in Yandex and Google search engines. The primary issue is to understand how frequently encountered queries reflect cultural representations and biases, shaping the collective perception of various ethnic groups. The aim of the article is to analyze and comprehend the dynamics of public opinions and views on various aspects of other cultures, including dietary, vestimentary, and sexual habits. The research focuses on identifying key markers that Russians associate with different ethnicities.
 The results demonstrate that the analysis of internet search queries can reflect a comprehensive level of public interest, fears, and apprehensions towards the cultural “Other.” The study provides a detailed view of the various forms of societal response, ranging from interest and curiosity to fears and prejudices. The analysis also revealed significant moments of intensification of interethnic tensions and changes in public discourse, particularly in the context of perceiving and interpreting cultural differences.
 The conclusions of the research emphasize the importance of an objective analysis of internet queries for understanding public views and opinions about different ethnic groups. The article will be useful for researchers in the fields of cultural studies, sociology, and for those interested in studying the dynamics of cultural interaction and the perception of the ethnic “Other” in contemporary society.

Once Again About the Problems of Preserving Objects of Immovable Cultural Heritage from the Standpoint of Collective and Individual Consumer Perception

The concept of attitude towards objects of immovable cultural heritage, formed more than a century ago, is relevant today, based on the premises that these material objects form an objective value in the perception and understanding of any individual, any society, any civilization. The purpose of the article is to conduct a preliminary analysis of the problems that form the understanding of the value of cultural heritage, preservation and careful treatment of it in the modes of restoration activities and restoration work. Achieving the goal can be the solution of a number of problems regarding the proper state protection of objects of immovable cultural heritage and the necessary assistance from the state, public institutions and international organizations, as well as taking into account the assigned status of the object in the matter of rescue, restoration and gentle scientific restoration. Currently existing directions and developments in a comprehensive assessment of architectural monuments of the past, observation methods, active comparative studies, and statistical measurements are considered as methodological and instrumental approaches to solving emerging problems. The results obtained by the authors included a study of the complex interaction and isolated influence on the category of value of such significant features-factors as evaluation criteria such as cultural and collective memory, historical reputation in their meaning for the self-identification of society and in the development of strategies in the field of preservation of cultural heritage objects and their use in the exploitation of the recreational potential of the destination by the tourism business. Examples from domestic restoration and construction practice and Western European experience, used to minimize the negative consequences of the increasing anthropogenic load on the territory, are discussed. At the end of the material, prospects for further research are indicated and the necessary conclusions are drawn.

Threshold Analysis of Static and Dynamic Occlusion in Urban Areas: A Connected Automated Vehicle Perspective

This study comprehensively explores static and dynamic occlusion issues in urban scenarios, focusing mainly on their interplay with the rising prevalence of connected automated vehicles (CAVs). We propose a unique methodology for pinpointing static and dynamic occlusions and examining the impacts of CAVs that integrate collective perception in their sensing systems. A crucial aspect of our investigation is identifying a critical point concerning the CAV penetration ratio, past which dynamic occlusion ceases to exert significant influence. Based on our investigation, a penetration rate of around 34% seems to alleviate the problems associated with dynamic occlusions. Nonetheless, our research also uncovers that issues related to static occlusion may endure even with increased CAV penetration levels, thus requiring additional mitigation approaches. Furthermore, this study broadens the understanding of static and dynamic occlusion, creating a new metric to explain the level of visibility in urban areas. The framework applied in our evaluations is disclosed in conjunction with this paper. This research represents a substantial advancement in understanding and improving the operation of CAVs in occluded scenarios.

Capturing residents’ perceptions of green spaces in densifying urban landscapes - The potentials of mental mapping

Understanding residents’ perceptions of green-blue infrastructure (GBI) is critical to ensure continued access to its associated benefits in growing and densifying urban landscapes. Physical availability and accessibility of green spaces alone do not directly translate to actual appreciation and use. Residents’ sense of place can determine if benefits from GBI are realized and how landscape changes may be perceived. In this study, set in sub-urban Stockholm, Sweden, we applied a mixed-methods approach combining mental mapping with follow-up interviews to investigate how such methodology can improve our understanding of residents’ perception of the recreational use of GBI. For the mental mapping exercise, participants drew, freehand, a map of appreciated neighborhood places for recreational purposes. Our results clearly show that mental mapping provides relevant information on individual and collective perceptions of recreational GBI, linkages between green-blue and gray infrastructure elements, and recreational hot-spots of importance to the local inhabitants. The unguided approach to welding local knowledge with spatial expressions makes the method well suited to contribute to a better understanding of plural senses of place with regards to the recreational use of GBI in rapidly urbanizing landscapes and an enhanced capacity to recognise locally appreciated recreational spaces in planning and practical management.

Racial/ethnic collective autonomy restriction and teacher fairness: predictors and moderators of student's perceptions of teacher support

The link between intrinsic motivation support from teachers (i.e., teacher support), academic motivation, and academic performance is well documented. However, evidence suggests that racial/ethnic minority students are less likely to perceive support from adults at school, compared to White students. The majority of existing research has emphasized the impact that school-level factors have on racial/ethnic minority students' perceptions of teacher support. However, less research has examined whether students' awareness of racial/ethnic inequality at the socio-structural level may also influence perceptions of teacher support. The present study explores this question and examines whether students' perceptions of race/ethnic based collective autonomy restriction (i.e., the extent to which an individual feels that other groups try and restrict their racial/ethnic groups' freedom to define and express their own social identity) and fair treatment from teachers influence these outcomes. Drawing on cross-sectional survey data from middle and high school students (N = 110), the present study found that racial/ethnic minority students reported greater perceptions of collective autonomy restriction, compared to White students, which mediated the link between students' racial/ethnic identity and perceived teacher support. Furthermore, past experiences with fair treatment from teachers were found to buffer the link between collective autonomy restriction and perceptions of teacher support. The practical implications of these findings for educators to better support students from underrepresented racial/ethnic backgrounds are discussed.

Hesperidin from Orange Peel as a Promising Skincare Bioactive: An Overview.

The pursuit for better skin health, driven by collective and individual perceptions, has led to the demand for sustainable skincare products. Environmental factors and lifestyle choices can accelerate skin aging, causing issues like inflammation, wrinkles, elasticity loss, hyperpigmentation, and dryness. The skincare industry is innovating to meet consumers' requests for cleaner and natural options. Simultaneously, environmental issues concerning waste generation have been leading to sustainable strategies based on the circular economy. A noteworthy solution consists of citrus by-product valorization, as such by-products can be used as a source of bioactive molecules. Citrus processing, particularly, generates substantial waste amounts (around 50% of the whole fruit), causing unprecedented environmental burdens. Hesperidin, a flavonoid abundant in orange peels, is considered to hold immense potential for clean skin health product applications due to its antioxidant, anti-inflammatory, and anticarcinogenic properties. This review explores hesperidin extraction and purification methodologies as well as key skincare application areas: (i) antiaging and skin barrier enhancement, (ii) UV radiation-induced damage, (iii) hyperpigmentation and depigmentation conditions, (iv) wound healing, and (v) skin cancer and other cutaneous diseases. This work's novelty lies in the comprehensive coverage of hesperidin's promising skincare applications while also demonstrating its potential as a sustainable ingredient from a circular economy approach.

Advanced Road Safety: Collective Perception for Probability of Collision Estimation of Connected Vehicles

In the dynamic landscape of vehicular communication systems, connected vehicles (CVs) present unprecedented capabilities in perception, cooperation, and, notably, probability of collision management. This paper’s main concern is the collision probability of collision estimation. Achieving effective collision estimation heavily relies on the sensor perception of obstacles and a critical collision probability prediction system. This paper is dedicated to refining the estimation of collision probability through the intentional integration of CV communications, with a specific focus on the collective perception of connected vehicles. The primary objective is to enhance the understanding of the potential probability of collisions in the surrounding environment by harnessing the collective insights gathered through inter-vehicular communication and collaboration. This improvement enables a superior anticipation capacity for both the driving system and the human driver, thereby enhancing road safety. Furthermore, the incorporation of extended perception strategies holds the potential for more accurate collision probability estimation, providing the driving system or human driver with increased time to react and make informed decisions, further fortifying road safety measures. The results underscore a significant enhancement in collision probability awareness, as connected vehicles collectively contribute to a more comprehensive collision probability landscape. Consequently, this heightened collective collision probability perception improves the anticipation capacity of both the driving system and the human driver, contributing to an elevated level of road safety. For future work, the exploration of our extended perception techniques to achieve real-time probability of collision estimation is proposed. Such endeavors aim to drive the development of robust and anticipatory autonomous driving systems that truly harness the benefits of connected vehicle technologies.

Towards an archaeology of everyday life in British Ionian Islands: the cultural itineraries of the Kythera Gin Bottles

SUMMARY During the course of the nineteenth century the island of Kythera, Southwest Greece, was part of the United States of Ionian Islands, under the control of the British empire. This paper explores the materiality of colonialism in local contexts, through the object itineraries of a group of stoneware bottles—a class of artefacts that continues to be represented in domestic assemblages locally today. We examine the diverse ways the vessels became entangled with the lives of individuals, colonialist agendas, and collective perceptions of identity, seeking to identify how the meanings associated with the objects and their relational connections shifted across time and space.

Perceptions Matter: Do Divergent Views of Management and Colleagues on Social Climate Drive Employee Engagement Through Organizational Identification and Growth Satisfaction?

A growing body of research has explored the conditions that motivate employees to engage at work. While employees’ attitudes and behaviors are socially influenced by their significant others’ perceptions, the divergent perceptions of organizational climate are underexplored. This study examines the socio-psychological mechanisms by which employees’ and managers’ perceptions of social climate enhance employee engagement at work. Based on the postulate that “ psychological state engagement” are the primary catalyst for “ behavioral engagement,” this study presents a serial mediation model that examines the role of divergent perceptions of social climate (as characterized by cooperation, shared codes and language, benevolence, and integrity) in fostering individual engagement through the mechanisms of organizational identification and growth satisfaction. Data were collected from both managers and employees, using a time-lagged design at two-time points. The findings revealed that managers’ collective perceptions of social climate were associated with organizational identification and growth satisfaction, which in turn fostered employee engagement at work. Contrary to expectations, there was no statistically significant relationship between employees’ collective perceptions of social climate and their engagement. However, individuals who had more favorable perceptions of the social climate (compare to colleagues’ collective perception) reported higher levels of organizational identification. These results point to ways in which social climate can impact employee engagement, and underscore the importance of taking divergent perceptions of organizations into account. They advance theories on the inherent tension between individuals’ desire for inclusion and the need to maintain a sense of individuality and distinctiveness.

A collective perception model for neighbor selection in groups based on visual attention mechanisms

The mechanisms by which individuals visually perceive and select others within a group to interact with are of fundamental importance to various collective motion behaviors. However, they remain poorly understood theoretically, partially due to the challenges of modeling neurological perception systems. Here, the classic zoom-lens visual attention model is introduced into collective perception, leading to an attention-based model with only a single parameter. Numerical experiments reveal that the proposed model offers a unified mechanism for collective perception, as reflected in three aspects. First, this model describes both conspecific (e.g. flocking) and heterospecific (e.g. predator-prey) collective behaviors. Second, this model unifies the well-known topological and visibility models in the context of neighbor selection in conspecific groups. Third, in the context of prey selection in heterospecific groups, the model can simultaneously replicate the well-known confusion and oddity effects. These findings demonstrate the fundamental role of visual attention underlying a diverse array of collective motion behaviors.

A psychological model of collective risk perceptions

Abstract Decades of research seek to understand how people form perceptions of risk by modeling either individual-level psychological processes or broader social and organizational mechanisms. Yet, little formal theoretical work has focused on the interaction of these 2 sets of factors. In this paper, I contribute to closing this gap by modifying a psychologically rich individual model of probabilistic reasoning to account for the transmission and collective emergence of risk perceptions. Using data from 357 individuals, I present experimental evidence in support of my main building assumptions and demonstrate the empirical validity of my model. Incorporating these results into an agent-based setting, I simulate over 1.5 billion social interactions to analyze the emergence of risk perceptions within organizations under different information frictions (i.e., limits on the availability and precision of social information). My results show that by focusing on information quality (rather than availability), groups and organizations can more effectively boost the accuracy of their emergent risk perceptions. This work offers researchers a formal framework to analyze the relationship between psychological and organizational factors in shaping risk perceptions.

Feedback-Regulated Information Fusion Approach for Optimizing Multiple Spread Control in complex Network

The information spread uses a social media platform, where one user intends to share information with others intentionally or non-intentionally. The rapid spread of information on social media platforms is a complex phenomenon influenced by many factors. However, the factors influencing this rapid spread in the online space still need to be discovered. Individuals utilize social media platforms to share their experiences regarding various events related to products or services. Given the intricate and multilayered nature of social media networks, the feedback received from each layer essentially mirrors the collective perceptions of the world. This process involves fusing information from each node within the network to arrive at a decision specific to the corresponding layer. And regulate the multiple spreads through the social networks. The system is verified by using a diffusion model to ensure correctness. The verification and validation show the suitability of the proposed system in controlling multiple spreading.

A imagem de enfermeiras(os) no Chile por meio de desenhos infantis: um estudo iconográfico

Abstract Objective To reveal the image of nursing professionals in Chile through the analysis of children’s drawings. Method This is an exploratory qualitative study, involving the collection of information through nine drawings made by children aged between 7 and 10 years, using free technique, and then were analyzed with the Iconographic Method proposed by Erwin Panofsky. Results Most drawings depict clinical activities of nurses, focusing predominantly on the technical dimension of the profession. Although nursing is commonly associated with a mostly female occupation, permeated by gender stereotypes, some participants were able to identify the presence and importance of the male role in this professional field. No iconographic elements were identified that would reinforce stigmas associated with nursing professionals, such as the view that they are supporters, aides, or mere medical assistants. Conclusions and implications for practice Children’s drawings serve as a reflection of the collective imagination of society. By studying them in relation to nursing, we can identify the advances of the profession and glimpse its near future. This research contributes to understanding the current image of the profession in society, and allows an analysis that goes further, helping to establish future directions and the evolution of this collective perception.

A Survey of Applications of Blockchain in Collective Decision-Making Scenarios in Swarm Robotics

Blockchain is a distributed ledger that was introduced to decentralize monetary systems. However, with time, the applications of blockchain in different realms have been identified. Swarm robotics is a field that combines swarm intelligence and robotics to solve real-world problems that cannot be solved by monolithic robots. Collective decision-making is one of the major behaviors implemented by swarm robotics. This study analyzes existing literature on the applications of blockchain in the collective decision-making scenarios in swarm robotics. Consequently, this study introduces a novel taxonomy to study the different applications effectively. The taxonomy categorizes existing literature into (i) application of blockchain in other areas of swarm robotics, (ii) application of blockchain in continuous collective decision-making scenarios, (iii) application of blockchain in discrete collective decision-making scenarios, (iv) application of blockchain in other discrete collective decision-making scenarios, and (v) application of blockchain in the collective perception scenario. Finally, the limitations of existing work such as excessive resource consumption and violation of swarm robotics principles are discussed.
