Double-Layer K-Means++ Clustering Method for Evaluation of Dispatchable Potential of Massive Regional 5G Base Stations

5G base stations (BSs), which are the essential parts of the 5G network, are important user-side flexible resources in demand response (DR) for electric power system. However, a 5G BS has little and difference dispatchable potential, how to make massive 5G BSs participate in DR conveniently is an urgent problem to be solved. Clustering is an effective solution. Aiming at the special requirements of big data analysis and dispatching difficulties brought by the massive and ultra-dense distribution of 5G BSs, this paper proposes a double-layer K-means++ clustering method for regional 5G BSs considering the main characteristics of 5G BSs. The proposed clustering method considers both the geographical location and power consumption characteristics of the regional 5G BSs to partition the 5G BSs into appropriate number of clusters. Besides, the comprehensive charging and discharging dispatchable potential evaluation indices are established based on the clustering results to evaluate the dispatchable potential of each cluster. The effectiveness of the proposed method and the dispatchable potential evaluation indices are verified through a case of 5000 5G BSs in Jiaxing, China. The simulation findings reveal that the performance of the proposed clustering method is better than classical clustering algorithm and the dispatchable potential of the 5G BSs clusters can be accurately analyzed by the proposed comprehensive indices, which lay the foundation for friendly and fine interaction between 5G BSs and the power grid.

Non-Intrusive Load Monitoring Method Considering the Time-Segmented State Probability

Appliance-level data is a prerequisite for establishing friendly two-way interactions between customers and the power company, and this data is now mainly obtained by non-intrusive load monitoring. However, as the number of loads increases, the number of possible appliances state combinations tends to grow exponentially, leading to a significant increase in the time of load identification. In order to reduce the search range of the load state combinations and shorten the algorithm response time, a non-intrusive load monitoring method based on the time-segmented state probability is proposed in this paper. Firstly, the affinity propagation (AP) clustering algorithm is introduced to obtain the power templates of the load, and then the power templates are used to count the time-segmented state probabilities. Secondly, a number of appliance state matrices are generated using the probabilities, and the optimal matrix is selected by the function as the identification result of the appliance state. Finally, the performance of the algorithm is tested on the public NILM dataset and compared to several state-of-the-art techniques. The results illustrate that the proposed method achieves an accuracy of 96% for load state identification and 89% for power decomposition of the load, and is able to meet the real-time application requirements.

Friends tell it like it is: Therapy culture, postfeminism and friendships between women

Feminist cultural studies researchers have produced a rich body of work showing how postfeminism and therapy cultures pervade a range of media. However, receiving less attention are questions of exactly how the neoliberal technologies of self implicated in these two cultural persuasions ‘land’, and are practised in everyday life. In this article, we forward an identity practice approach to understand the interrelated cultures of therapy and postfeminism using data from a qualitative investigation of women’s friendships in Aotearoa New Zealand. We are interested in how the cultural resources concerning postfeminism and the ‘psy complex’ are used flexibly within friendship interactions in concert with other identities, such as national identities and caring identities. Overall, aligning with previous feminist analyses of media artefacts, we find that as postfeminist and therapeutic subjectivity-making entwine with the moral orders of women’s friendships, women carry out their self-surveillance and self-transformation work collaboratively. Yet, remaining attentive to how women tailor cultural resources in their creative identity work leads us to a more hopeful reading. We suggest that the confidence gained by women through their therapised friendships should also be acknowledged for its nourishing qualities.

The interplay of positive and negative intergroup contact: Experiences of Latino/a Youth in the U.S.

This study examines the interplay of positive and negative intergroup contact with majority group members from the perspective of ethnic minority youth. Taking a social identity approach, we posit that negative contact experiences (i.e., hostile interactions) may undermine the benefits of some positive contact experiences (i.e., friendly interactions) for minority contact orientations (e.g., openness to and anxiety about cross-group interactions). Conversely, for other positive contact experiences, in particular high-quality forms of positive contact (e.g., friendship), we expect that their beneficial effects will not be undermined, and that the adverse effects of negative contact may even be buffered by such high-quality positive contact experiences. We tested our predictions in a sample of U.S. Latino/a youth (N = 126) nested in 41 classrooms, using a multilevel design. As expected, friendly interactions predicted more favorable contact orientations only in the absence of negative contact, while high-quality positive contact robustly predicted more favorable contact orientations and even buffered negative contact effects. These findings illuminate how negative contact can cast a long shadow over the inclusion of minority youth in intergroup settings; moreover, they indicate the importance of curbing hostile treatment targeting minority youth and of promoting high-quality positive contact over and above mere friendly interactions.

Top-level diplomacy in the relations between Russia and the UAE

Multi-faceted partnership is developing between Russia and the UAE - in the trade, economic, political, humanitarian spheres, as well as in the field of high technologies. The positions of both countries on pressing international problems are close to each other particularly on security issues, fighting against terrorism, and the conflict settlement in the Middle East. There is a tendency for the establishing of the close bilateral relations in strategically important areas. The historical visit of President Putin to the UAE on October 15, 2019 was a clear proof of the development of friendly relations and close interaction between the two countries.

Implicit guidance in educational online collaboration: Supporting highly qualitative and friendly knowledge exchange processes

Group awareness tools that implicitly guide users by presenting information about intangible cognitive (e.g., knowledge) and emotional (e.g., friendliness) group aspects have different effects in educational online collaboration. Prior research has focused on smaller group settings, with examining different tools separately or in combination without systematically disentangling their specific effects. Social media learning communities may particularly benefit from combining cognitive and emotional group awareness support, as emotional processes are closely related to cognitive processes in such settings. To systematically test this, we conducted a 2 × 2 between-subjects experiment (N = 148), in which participants were provided with a wiki-like environment and, except for the control condition, dynamic cognitive (based on knowledge tests) and/or emotional (based on sentiment analysis) group awareness information. As a theoretical implication, the results provide insights into the positive effects of single cognitive group awareness information on produced content quality by highlighting different knowledge levels. Single emotional group awareness information moreover positively affects the friendliness of exchange processes, which depends on the learners’ need for affect. Neither single cognitive group awareness support nor the interaction with emotional group awareness support reveals direct positive effects on learning posttest performance. However, emotional group awareness tools have the potential to indirectly affect well-being and learning posttest performance, mediated via friendly interactions. As a practical implication, knowledge bar visualizations should be considered to improve outcome quality in social media collaboration. Besides, the use of dynamic sentiment analysis for assessing and visualizing different friendliness levels promotes discussions in a polite and respectful manner.

The Pap Smear Test Experience of Iranian Women: A Qualitative Study

Aims: The Pap smear test as the primary screening test for cervical cancer has a low application rate among Iranian women. This study aimed to explore Iranian women’s Pap smear test experiences at healthcare centers. Participants & Methods: This qualitative study was carried out in Varamin City, in 2018. To this end, 15 women admitted to healthcare centers were selected using purposive sampling. Inclusion criteria consisted of married women aged 20-50 years with a history of Pap smear, willingness to participate in the study, Iranian nationality, and ability to speak. To explore the women’s views and experiences, semi-structured interviews were conducted, recorded, transcribed, and analyzed using content analysis. Four criteria, namely credibility, confirmability, dependability, and transferability were used to verify the accuracy and consistency of the data. Findings: The data analysis yielded five main categories, including "intention to perform the test","policies and the administrative system", "social factors helping to perform the test", "barriers to perform the test", and "motivational factors to perform the test". From the participants’ perspective, risk concepts, and supportive policies were critical in enhancing test performance. Conclusions: The results showed that the women’s Pap smear test performance depended on some factors including convenient and friendly interactions with healthcare providers, family support, encouraging policies and laws, and awareness. The cooperation of other organizations to perform a Pap smear test is also emphasized.

The problem of the use of hormonal therapy aimed for sex correction by transgender persons on their own initiative

In recent years, the demand for feminizing and masculinizing hormone therapy has increased significantly among transgender people around the world. There are no such studies in Russia and the amount of medical information on the transgender population is limited. to assess the number of transgender patients who take hormone therapy without a doctor's prescription and to characterize the medicines they use. data from 1117 transgender patients were included in to analysis: 44.01% (n=515) of them were trans women, 55.99% (n=630) were trans men. Patients applied to the "Scientific Center for Personalized Medicine" in order to receive medical care. Half of transgender people (53.6%) are already taking hormonal drugs. More often transgender women (76.7%), less often transgender men (32.3%). In this case, only 8.6% turned to endocrinologists for the therapy prescription. Many patients used unlicensed drugs, use irrational schemes and combinations, often overdose. A significant number of transgender people start using hormone replacement therapy on their own initiative, without the doctor's supervision. The solution to this problem could be incensement of knowledge level in doctors and patients to create a friendly environment and productive interaction between therapists, endocrinologists and transgender people, as well as the organization of consulting centers within public medical institutions.

Does a prosocial attitude reduce risky driving behaviour under time pressure?

Time pressure could make drivers exhibit more risky driving behaviour. Attitudes can influence people’s behaviours, but few studies have explored the influence of prosocial attitudes on driving behaviour. The purpose of this study was to explore the influence of prosocial attitudes on driving behaviour under time pressure. A 2 (high/low prosocial attitude) *2 (present/no time pressure) mixed design was used to investigate the interaction between prosocial attitude and time pressure on driving behaviour. Prosocial attitudes and time pressure have a significant main effect on driving behaviour. Drivers with high prosocial attitudes made lane changes at a greater distance from pedestrians and decelerated to a greater degree than drivers with low prosocial attitudes when interacting with pedestrians. Under time pressure, people drive faster and accelerate more quickly. Specifically, we found an interaction between time pressure and prosocial attitudes on driving behaviour. Drivers with low prosocial attitudes showed higher speeds than drivers with high prosocial attitudes under the time pressure scenario on foggy roads. The results showed that high prosocial attitudes lead to friendly interactions with pedestrians and careful driving in specific situations, even under time pressure. The present study not only expands the research on driving behaviour and attitude but can also provide some data support and guidance for driver selection and training.

Players' Stories and Secrets in Animal Crossing

Animal Crossing is an online multiplayer game that supports social communication and collaboration. Its recent version, New Horizons, is immensely popular having sold over 32 million copies worldwide, with many players attracted to the opportunities it provides to remotely socialize during the COVID-19 pandemic. To understand players' increased positive emotions and social interactions, we surveyed 119 of them betweenMay and December 2020 and conducted remote interviews with 25 respondents. We identified the social dynamics among players and with non-player characters (NPCs), and analyzed how positive social interactions were facilitated under player-generated narratives and game-determined narratives. Based on our empirical analyses, we have extended our understanding of how to create positive, safe, and friendly interactions: (1)the design of mood-improving game worlds with flexible game tasks, (2) implementation of game-determined activities with social implications, (3) provision of player rewards to reinforce their social interactions, and (4)creation of opportunities to integrate NPCs' game-determined narratives into player-generated narratives.

Formal specification and verification of fault location, isolation and service restoration of local topology model based on distributed processing for active distribution network

Active distribution network (ADN) technology, as an important trend of the future smart distribution grid, is able to effectively absorb distributed energy resource (DER), to reasonably optimise grid-load operation characteristics, and to safely support the reliability of power supply. Through enhancing energy utilisation efficiency and friendly interaction with user access, ADN technology is also able to comprehensively improve the power supply reliability of the distribution network. However, distributed feeder automation (FA), as an important part of ADN technology, will also meet new problems and challenges with the access of DER in the distribution network. The formal method can analyse the correctness and effectiveness of a distributed fault processing algorithm from mathematical logic, which provides an important theoretical basis for distributed fault processing. The focus herein is on the formal description and verification of topology modelling in fault location, isolation, and service restoration (FLISR) based on distributed processing. By abstracting and simplifying the complex power system features, the adaptability of the formal method is solved. The logical correctness of the topology model in FLISR based on distributed processing is verified. Finally, the distributed local topology model and algorithm is verified through a formal method using an actual ADN example.

Southern Green Cultural Criminology and Environmental Crime Prevention: Representations of Nature Within Four Colombian Indigenous Communities

This exploratory study develops a “southern green cultural criminology” approach to the prevention of environmental harms and crimes. The main aim is to understand differing cultural representations of nature, including wildlife, present within four Colombian Indigenous communities to evaluate whether they encourage environmentally friendly human interactions with the natural world, and if so, how. The study draws on primary data gathered by the Indigenous authors (peer researchers) of this article via a set of interviews with representatives of these four communities. We argue that the cosmologies that these communities live by signal practical ways of achieving ecological justice and challenging anthropocentrism.

Mediating Close Friendship Intimacy in Times of (Social) Distance

This article presents mediated intimacy in friendships as a necessary but difficult course of action to bridge physical absence between close friends. Following migration research to picture the mediation of intimacy of transnational family members, differences regarding the communicative behaviour, and specifically, the obligation to communicate contrasts distant friendships with translocal family interactions. Drawing on a German study on friendship communication, this paper asks the question how to derivate measures for profound friendship exchange in social distance, with regard to the current COVID-19 pandemic. Findings reveal communication media are definitely useful to keep up existing friendships but they also prevent meaningful friendship interaction. Accordingly, this paper contributes to the discussion of mediated communication and the production of mediated intimacy in friendships and highlights potential prospects to enhance physically distanced friendships.

Key components of integrated energy system’s source side and their influence on integrated energy system

Integrated energy supply and emerging new energy is a sign of transformation of energy system for environmental protection. This paper firstly models the key components of source side in integrated energy system. On the one hand, this paper models integrated energy supply and energy conversion devices involving multiple energy systems, on the other hand, it models new energy which is rapidly growing, so that all of these energy supply methods can serve the coordinated dispatch of integrated energy system. Then this paper focuses on CHP with heat storage which is a typical energy supply method involving both integrated energy supply and energy conversion. Through case study, we find that the heat storage system can bring friendly interaction between heat and power system, enhance the flexibility of integrated energy system, and decouple complex integrated energy system, so as to improve the social economic welfare.

Ground Truth in Network Communities and Metadata-Aware Community Detection: A Case of School Friendship Network

Real-world networks are everywhere and can represent biological, technological, and social interactions. They constitute complicated structures in terms of type of things and their relations. Understanding the network requires better examination of the network structure that can be achieved at various scales including macro, meso, and micro. This research is concerned with meso scale for a student best friendship network where sub-structures in which groups of entities (students) take different functions. In this study we address the following research questions: To what extent would NeoSBM as a stochastic process underlie best friendship interaction and in -turn ground truth interactions (i.e. reported best friendship)? Do metadata such as gender or class contribute to this understanding? How can one support school managers from a meta-data aware community detection perspective? Our findings suggest that metadata aware community detection can be an effective method in supporting decision-making for class formation and group formation for in and out school activities.

Cognitive Emotional Interaction Model of Robot Based on Reinforcement Learning

In order to enhance the cognitive emotional computing ability of robot, a cognitive emotional interaction model of robot based on reinforcement learning is proposed, which combines immediate feedback and long-term trend according to PAD(Pleasure-Arousal-Dominance) emotional space. Firstly, according to the psychology theory of interpersonal communication, the human emotion generation process is simulated to generate human-like emotions, and the three influencing factors of similarity, positivity and empathy are extracted. Secondly, the relationship between the response emotion+ state and the contexted long-term emotion state is established by using the global co-ordination feature of reinforcement learning, so as to model the robot emotion generation process. Then, three factors are incorporated into the model reward mechanism for the evaluate of the interactive emotion state, to update the model and get the optimal emotional strategy. Finally, the optimal emotional state corresponding to the obtained optimal emotional strategy is used to update the robot's emotional state transition probability, and based on the sentiment values of the six basic emotional states in space, them are mapped to continuous emotional space to get the optimal response emotional value of the robot. Subjective and objective comparison experiments show that the model in this paper can effectively increase the delicateness, continuity, positivity and empathy of the robot's emotional expression, and can effectively reduce the robot's dependence on external emotional stimuli, further improving the harmonious and friendly human-computer interaction.

Can Dogs' Origins and Interactions with Humans Affect Their Accomplishments? A Study on the Responses of Shelter and Companion Dogs during Vocal Cue Training.

Simple SummaryThe life history of animals is an important aspect to be considered when behavior, welfare, or cognition is investigated. Here, we aimed to study the behavioral responses of dogs with different origins—shelter and companion dogs—when learning two basic vocal cues (“sit” and “paw”), as well as possible associations between dogs’ responses and the behaviors of the trainers. Shelter dogs responded to more cues per session, were faster in their responses, and needed fewer repetitions of cues to respond than companion dogs. Moreover, shelter dogs spent more time wagging their tails during the sessions. Some behaviors of the trainers were associated with dogs’ behaviors—the use of a reproachful tone of voice, although associated with dog performance, was also linked to the exhibition of behaviors indicative of discomfort on the part of dogs. On the other hand, the use of a neutral tone of voice and laughter, in addition to being connected to performance, was also associated with behaviors indicative of excitement. These results suggest that shelter dogs’ capacities for learning vocal cues are not affected by the shelter environment. Furthermore, shelter dogs showed greater interest in the sessions than companion dogs, possibly due to the social deprivation in their routine. Our outcomes also point to a connection between friendly interactions during training and the dogs’ performance, and possibly their emotional state. The quality of the interactions seems to affect dogs’ performance and welfare more strongly than their origins.The inclusion of life history as a possible influential factor is pivotal in studies on behavior, welfare, and cognition. Shelter dogs have usually experienced a life involving poor social interactions with humans. Thus, we aimed to investigate the behavioral responses of shelter dogs (SDs) and companion dogs (CDs) during the training of two vocal cues (“sit”, “paw”), as well as the possible associations between their responses and the behaviors of trainers. We studied 15 SDs and 15 CDs in up to eight five-minute training sessions. Dogs’ and trainers’ behaviors were recorded and analyzed (through GLM, GLMM, correlation and Mann–Whitney tests). Shelter dogs responded to more cues per session, with shorter latencies and fewer repetitions of cues. Moreover, SDs spent more time wagging their tails. Dogs’ sex and trainers’ behaviors were also associated with differences in dogs’ responses. The use of a reproachful tone of voice was associated with a greater number of cues responded to, shorter latencies, and fewer repetitions of cues. However, this type voice/discourse was also linked to a greater exhibition of non-training behaviors (e.g., exploring the room or jumping on the trainer), and to dogs spending less time next to the trainer and wagging their tails. On the other hand, the use of a neutral tone of voice and laughter, besides being linked to performance, was also associated with longer durations of tail wagging. Furthermore, the duration of the trainers’ orientation to dogs was correlated with the orientation of the dogs to the trainers. Our data suggest that, even when having experienced social deprivation from humans, SDs’ capacities to learn vocal cues were preserved, possibly due to ontogenic homeostasis processes. Shelter dogs’ greater interest in the sessions may be also credited to their socially-deprived routine. Our outcomes also point to an association between friendly interactions during training and dog performance and excitement, which suggests that such interactions may have the potential to improve SD welfare.
