InteractNet: Social Interaction Recognition for Semantic-rich Videos

The overwhelming surge of online video platforms has raised an urgent need for social interaction recognition techniques. Compared with simple short-term actions, long-term social interactions in semantic-rich videos could reflect more complicated semantics such as character relationships or emotions, which will better support various downstream applications, e.g., story summarization and fine-grained clip retrieval. However, considering the longer duration of social interactions with severe mutual overlap, involving multiple characters, dynamic scenes, and multi-modal cues, among other factors, traditional solutions for short-term action recognition may probably fail in this task. To address these challenges, in this article, we propose a hierarchical graph-based system, named InteractNet, to recognize social interactions in a multi-modal perspective. Specifically, our approach first generates a semantic graph for each sampled frame with integrating multi-modal cues and then learns the node representations as short-term interaction patterns via an adapted GCN module. Along this line, global interaction representations are accumulated through a sub-clip identification module, effectively filtering out irrelevant information and resolving temporal overlaps between interactions. In the end, the association among simultaneous interactions will be captured and modelled by constructing a global-level character-pair graph to predict the final social interactions. Comprehensive experiments on publicly available datasets demonstrate the effectiveness of our approach compared with state-of-the-art baseline methods.

Exploring the coevolution of residents and recyclers in household solid waste recycling: Evolutionary dynamics on a two-layer heterogeneous social network

China’s household solid waste recycling system has long faced the challenge of recycling formalization. This process is affected by the complexity of the interdependence of the recycler and resident decisions. The aim of this study was to gain a better understanding of the coevolution of residents’ and recyclers’ recycling decisions. To this end, this study applied agent-based modeling and network-based evolutionary game methods to construct evolutionary game models based on a two-layer social network. The two layers of heterogeneous social networks depicted the connections between residents and recyclers, respectively. Residents and recyclers choose either formal or informal recycling strategies within layers according to evolutionary game theory. Waste flows and cash flows underlie the interdependent coevolution between the two layers. Using this model, the effects of resident subsidies, recycler subsidies, and regulatory policies on the coevolution of residents and recyclers were simulated. The results showed that the impact of policies on recycling systems relies on long-term social interaction. The trends in the strategic evolution of residents and recyclers were similar, and emerged from their interdependence and mutual influence. Resident-oriented subsidy incentives can promote formal recycling stably and positively. However, recycler subsidies and regulatory policies have opposite marginal promotion effects, as is reflected by the fact that the evolution of formal recycling is insensitive to high recycler subsidies and sensitive to high-intensity regulatory policies. These findings provide a more comprehensive insight into the development of recycling systems and inform the design of waste management policies.

Long-Term Social Human-Robot Interaction for Neurorehabilitation: Robots as a Tool to Support Gait Therapy in the Pandemic.

COVID-19 pandemic has affected the population worldwide, evidencing new challenges and opportunities for several kinds of emergent and existing technologies. Social Assistive Robotics could be a potential tool to support clinical care areas, promoting physical distancing, and reducing the contagion rate. In this context, this paper presents a long-term evaluation of a social robotic platform for gait neurorehabilitation. The robot's primary roles are monitoring physiological progress and promoting social interaction with human distancing during the sessions. A clinical validation with ten patients during 15 sessions were conducted in a rehabilitation center located in Colombia. Results showed that the robot's support improves the patients' physiological progress by reducing their unhealthy spinal posture time, with positive acceptance. 65% of patients described the platform as helpful and secure. Regarding the robot's role within the therapy, the health care staff agreed (>95%) that this tool can promote physical distancing and it is highly useful to support neurorehabilitation throughout the pandemic. These outcomes suggest the benefits of this tool to be further implemented in the pandemic.

Complex patterns of dopamine-related gene expression in the ventral tegmental area of male zebra finches relate to dyadic interactions with long-term female partners.

Dopaminergic projections from the ventral tegmental area (VTA) to multiple efferent targets are implicated in pair bonding, yet the role of the VTA in the maintenance of long-term pair bonds is not well characterized. Complex interactions between numerous neuromodulators modify activity in the VTA, suggesting that individual differences in patterns of gene expression in this region may explain individual differences in long-term social interactions in bonded pairs. To test this hypothesis we used RNA-seq to measure expression of over 8000 annotated genes in male zebra finches in established male-female pairs. Weighted gene co-expression network analysis identified a gene module that contained numerous dopamine-related genes with TH found to be the most connected gene of the module. Genes in this module related to male agonistic behaviors as well as bonding-related behaviors produced by female partners. Unsupervised learning approaches identified two groups of males that differed with respect to expression of numerous genes. Enrichment analyses showed that many dopamine-related genes and modulators differed between these groups, including dopamine receptors, synthetic and degradative enzymes, the avian dopamine transporter and several GABA- and glutamate-related genes. Many of the bonding-related behaviors closely associated with VTA gene expression in the two male groups were produced by the male's partner, rather than the male himself. Collectively, results highlight numerous candidate genes in the VTA that can be explored in future studies and raise the possibility that the molecular/genetic organization of the VTA may be strongly shaped by a social partner and/or the strength of the pair bond.

Society’s Perception on Residences in Development Area Attachment: A Case Study of PLPBK in Tulusrejo Village, Lowokwaru Sub-District, Malang City

This study involved residents of RT 02 and RT 03, Tulusrejo sub-district. The setting of this study was one of the government’s target residence related to the project of Community-Based City and Residence Planning or Penataan Lingkungan Pemukiman Berbasis Komunitas (PLPBK), which success depended on society’s participation. Social bonds that result from long-term social interaction and life journey create emotional feeling upon their residences (Hummon, 1990). The place where people live and do their daily activities has certain deep meaning for them (Kyle et al, 2004), which at the same time affects the social psychological domain called place attachment (Lewicka, 2011). Thus, it was necessary to create strong social bonds and strengthen residents’ place attachment feeling for the success of the PLPBK program. In this study, social network mapping was analyzed using the Social Network Analysis (SNA). Meanwhile, to explain residents’ perception on their residence, Multidimensional Scaling was used. The result of this study exhibits that some social groups were formed upon certain similarities and membership of a certain organization. Besides, social groups were also formed by similar community attachment.Int. J. Soc. Sc. Manage. Vol. 5, Issue-1: 46-50

Cossacks learning a wealth of experience and good neighborliness can be an important resource for the harmonization of ethnic relations in the Kuban region.

Social networking in an academic conference context: insights from a case study

Purpose – The purpose of this paper is to propose a conference-based online social network (OSN) for academics’ knowledge sharing and collaboration around and beyond a conference, while exploring the entanglement of the social and technical aspects of the system. Design/methodology/approach – Following an exploratory study, an OSN prototype was developed and implemented in ECIS 2014. The usage of the OSN platform was monitored and in-depth interviews were conducted with seven of its active users. Findings – Academic researchers have positive attitudes toward using conference-based OSN. However, there is a gap between academics’ perceptions and their actual behavior. Several barriers for engagement were identified, leading to technical and social recommendations, including the following needs: integrating the OSN platform with other conference information systems; addressing privacy concerns; allowing on-going collaboration; increasing OSN vitality; using the wisdom of the crowd; and promotion and its timing. Research limitations/implications – The case study highlighted existing benefits, and identified potential future benefits from implementing a conference-based OSN. Future research is required to generalize the findings and evaluate the proposed strategies for enhancing user engagement. Practical implications – This study revealed the set of considerations that should be taken upon launching a new academic OSN, which are beyond the technical issues per se. Social implications – The paper presents the expected benefits from, and existing barriers to using a conference-based OSN, and suggests recommendations for encouraging academics to engage in such OSN, in order to enhance long-term social interactions, knowledge sharing and collaboration among conference participants. Originality/value – This is a first study to examine a conference-based OSN.

Towards Long-Term Social Child-Robot Interaction: Using Multi-Activity Switching to Engage Young Users

Social robots have the potential to provide support in a number of practical domains, such as learning and behaviour change. This potential is particularly relevant for children, who have proven receptive to interactions with social robots. To reach learning and therapeutic goals, a number of issues need to be investigated, notably the design of an effective child-robot interaction (cHRI) to ensure the child remains engaged in the relationship and that educational goals are met. Typically, current cHRI research experiments focus on a single type of interaction activity (e.g. a game). However, these can suffer from a lack of adaptation to the child, or from an increasingly repetitive nature of the activity and interaction. In this paper, we motivate and propose a practicable solution to this issue: an adaptive robot able to switch between multiple activities within single interactions. We describe a system that embodies this idea, and present a case study in which diabetic children collaboratively learn with the robot about various aspects of managing their condition. We demonstrate the ability of our system to induce a varied interaction and show the potential of this approach both as an educational tool and as a research method for long-term cHRI.

Influence of long-term social interaction on chirping behavior, steroid levels and neurogenesis in weakly electric fish

Social interactions dramatically affect the brain and behavior of animals. Studies in birds and mammals indicate that socially induced changes in adult neurogenesis participate in the regulation of social behavior, but little is known about this relationship in fish. Here, we review studies in electric fish (Apteronotus leptorhychus) that link social stimulation, changes in electrocommunication behavior and adult neurogenesis in brain regions associated with electrocommunication. Compared with isolated fish, fish living in pairs have greater production of chirps, an electrocommunication signal, during dyadic interactions and in response to standardized artificial social stimuli. Social interaction also promotes neurogenesis in the periventricular zone, which contributes born cells to the prepacemaker nucleus, the brain region that regulates chirping. Both long-term chirp rate and periventricular cell addition depend on the signal dynamics (amplitude and waveform variation), modulations (chirps) and novelty of the stimuli from the partner fish. Socially elevated cortisol levels and cortisol binding to glucocorticoid receptors mediate, at least in part, the effect of social interaction on chirping behavior and brain cell addition. In a closely related electric fish (Brachyhypopomus gauderio), social interaction enhances cell proliferation specifically in brain regions for electrocommunication and only during the breeding season, when social signaling is most elaborate. Together, these studies demonstrate a consistent correlation between brain cell addition and environmentally regulated chirping behavior across many social and steroidal treatments and suggest a causal relationship.

Historicizing in critical policy analysis: the production of cultural histories and microhistories

The practice of critical policy analysis often emphasizes the importance of historicizing the present. However, there is very little guidance for critical policy analysts on the methodical production of histories. In this paper, I meet this need by arguing for the use of methodologies embedded in the production of both cultural histories and microhistories. I show how the historical narratives that are produced by critical policy analysts must be able to reveal patterns of long-term social interactions and domination, while simultaneously showing how people on a smaller temporal scale still disrupt and bend these social structures to their needs. Most importantly, I argue that using such methodologies allows critical policy analysts to practice a form of historicizing that explicitly adheres to an epistemological stance that emphasizes the social construction of knowledge through power relationships.

Multimodal Child-Robot Interaction: Building Social Bonds

For robots to interact effectively with human users they must be capable of coordinated, timely behavior in response to social context. The Adaptive Strategies for Sustainable Long-Term Social Interaction (ALIZ-E) project focuses on the design of long-term, adaptive social interaction between robots and child users in real-world settings. In this paper, we report on the iterative approach taken to scientific and technical developments toward this goal: advancing individual technical competencies and integrating them to form an autonomous robotic system for evaluation "in the wild." The first evaluation iterations have shown the potential of this methodology in terms of adaptation of the robot to the interactant and the resulting influences on engagement. This sets the foundation for an ongoing research program that seeks to develop technologies for social robot companions.

Glucocorticoid receptor blockade inhibits brain cell addition and aggressive signaling in electric fish, Apteronotus leptorhynchus

When animals are under stress, glucocorticoids commonly inhibit adult neurogenesis by acting through glucocorticoid receptors (GRs). However, in some cases, conditions that elevate glucocorticoids promote adult neurogenesis, and the role of glucocorticoid receptors in these circumstances is not well understood. We examined the involvement of GRs in social enhancement of brain cell addition and aggressive signaling in electric fish, Apteronotus leptorhynchus. In this species, long-term social interaction simultaneously elevates plasma cortisol, enhances brain cell addition and increases production of aggressive electrocommunication signals (“chirps”). We implanted isolated and paired fish with capsules containing nothing (controls) or the GR antagonist, RU486, recorded chirp production and locomotion for 7d, and measured the density of newborn cells in the periventricular zone. Compared to isolated controls, paired controls showed elevated chirping in two phases: much higher chirp rates in the first 5h and moderately higher nocturnal rates thereafter. Treating paired fish with RU486 reduced chirp rates in both phases to those of isolated fish, demonstrating that GR activation is crucial for socially induced chirping. Neither RU486 nor social interaction affected locomotion. RU486 treatment to paired fish had a partial effect on cell addition: paired RU486 fish had less cell addition than paired control fish but more than isolated fish. This suggests that cortisol activation of GRs contributes to social enhancement of cell addition but works in parallel with another GR-independent mechanism. RU486 also reduced cell addition in isolated fish, indicating that GRs participate in the regulation of cell addition even when cortisol levels are low.

Residual social, memory and oxytocin-related changes in rats following repeated exposure to γ-hydroxybutyrate (GHB), 3,4-methylenedioxymethamphetamine (MDMA) or their combination

There has been little investigation of the possible lasting adverse effects of γ-hydroxybutyrate (GHB). This study aims to study whether GHB produces residual adverse effects on memory and social behaviour in rats and lasting changes in brain monoamines and oxytocin-related gene expression. Rats received daily intraperitoneal injections of GHB (500 mg/kg), methylenedioxymethamphetamine (MDMA; 5 mg/kg) or their combination (GHB/MDMA) over ten consecutive days. Locomotor activity and body weight were assessed during the dosing period and withdrawal-related anxiety was assessed 24 h after drug cessation. After a washout of 4 weeks, rats were tested on the emergence, social interaction, and object recognition tasks over a 2-week period. Monoamine levels in cortex and striatum, and hypothalamic oxytocin and oxytocin receptor mRNA, were then assessed. MDMA and GHB/MDMA caused modest sensitization of locomotor activity over time, while sedative effects of GHB diminished with repeated exposure. GHB-treated rats showed reduced social interaction 24 h after the final dose, indicating GHB withdrawal-induced anxiety. All drug-treated groups displayed residual deficits in social interaction and object recognition. No changes in monoamine levels were detected 8 weeks post-drug. However, MDMA pre-exposure increased hypothalamic oxytocin mRNA while GHB pre-exposure upregulated oxytocin receptor mRNA. GHB/MDMA pre-exposure caused intermediate changes in both of these measures. GHB treatment caused residual impairments in memory and social behaviour and increases in anxiety, paralleling the lasting adverse effects of MDMA. Both drugs caused lasting neuroadaptations in brain oxytocin systems and this may be related to the long-term social interaction deficiencies caused by both drugs.

Social Environment and Sex Differentiation in the False Clown Anemonefish, Amphiprion ocellaris

Plasticity in sex differentiation is known to be common in teleost fishes. Anemonefishes are protandrous; females are the largest and dominant members of social groups, displaying frequent aggressive behavior towards other members of groups. The second-ranked individuals become males and others remain as non-reproductive individuals. Here we examine the influence of social interaction in-group on sex differentiation in the false clown anemonefish, Amphiprion ocellaris, under laboratory conditions. Three juvenile anemonefish were kept in a tank for 180 days and their behaviors observed once a month. The social rank of individuals was distinguishable by their interactions in a group, with rank order clearly correlated with aggressive and appeasing behaviors. The dominant individuals occupied the shelter in the tank from the start to completion of the observation period. The body mass of dominant individuals increased compared to group-housed control fish, while third-ranked individuals showed growth suppression. The ratio of testicular tissue in gonads increased in dominant and second-ranked individuals but decreased in the third-ranked individuals. Differences in the plasma concentrations of estradiol, testosterone, and cortisol were not significant, but the concentration of 11-ketotestosterone was significantly higher in dominant individuals. These results suggest that, in false clown anemonefish, reproductive suppression of lower-ranked individuals becomes apparent in the first stage of group formation, and sex differentiation of upper-ranked individuals is gradually determined by long-term social interactions.

Social interaction and cortisol treatment increase cell addition and radial glia fiber density in the diencephalic periventricular zone of adult electric fish, Apteronotus leptorhynchus

In electric fish, Apteronotus leptorhynchus, both long-term social interaction and cortisol treatment potentiates chirping, an electrocommunication behavior that functions in aggression. Chirping is controlled by the diencephalic prepacemaker nucleus (PPn-C) located just lateral to the ventricle. Cells born in adult proliferative zones such as the periventricular zone (PVZ) can migrate along radial glial fibers to other brain regions, including the PPn-C. We examined whether social interactions or cortisol treatment influenced cell addition and radial glia fiber formation by (1) pairing fish (4 or 7 days) or (2) implanting fish with cortisol (7 or 14 days). Adult fish were injected with bromodeoxyuridine 3 days before sacrifice to mark cells that were recently added. Other fish were sacrificed after 1 or 7 days of treatment to examine vimentin immunoreactivity (IR), a measure of radial glial fiber density. Paired fish had more cell addition than isolated fish at 7 days, coinciding temporally with the onset of socially induced increase in chirping behavior. Paired fish also had higher vimentin IR at 1 and 7 days. For both cell addition and vimentin IR, the effect was regionally specific, increasing in the PVZ adjacent to the PPn-C, but not in surrounding regions. Cortisol increased cell addition at 7 days, correlating with the onset of cortisol-induced changes in chirping, and in a regionally specific manner. Cortisol for 14 days increased cell addition, and cortisol for 7 days increased vimentin IR but in a regionally non-specific manner. The correlation between treatment-induced changes in chirping and regionally specific increases in cell addition, and radial glial fiber formation suggests a causal relationship between such behavioral and brain plasticity in adults, but this hypothesis will require further testing.

Digital Clothes: Active, Dynamic, and Virtual Textiles and Garments

This article will examine the probable and possible pitfalls offered to consumers and designers by the potential of textiles and garments that are responsive, active, interactive, and aware, using technologies inherited from other craft fields such as medical sensing and information technology.These developments present obvious, and much discussed, opportunities for the design of functional garments for applications in dangerous industries, sports, rescue, and the military. However, the effect on the already complex dynamic between garment and everyday wear has not been so well examined. Using the social effects of the uptake of other now ubiquitous technology devices such as mobile phones and the Internet as a model for social impact, this article will take a look into the possible near future to see both what is possible, but also what can go wrong with active garment fashion.This examination of the “digital” in garment manufacture moves well beyond the current, often rather clumsy incorporation of wires, sensors, and novelty “glow in the dark” fiber optics into conventional clothes. Rather, it examines the maturing of a field in which revolutionary display technologies and bio-feedback sensing are merging with textiles to produce totally natural feeling and looking fabrics that can not only change their overall color, but can display complex patterns, as well as respond to stimuli from wearer and environment. Aspects such as the effects on personal health, social conventions, and economic costs will be considered.The article will also consider the domain of clothing and fashion for people who inhabit “virtual” environments, interacting with other people in real time. Unlike more familiar computer games, these online environments involve extensive, long-term social interaction between participants. Unfortunately, the choice of “costume” for the visual representation of each player, currently very limited, has become a frustration for individuals, and threatens to limit the social agency and growth of these environments. The problems of designing and implementing credible and engaging fashions for virtual reality are therefore also examined.

Early androgenization and aggression pheromone in inbred mice

Three experiments were conducted to investigate the effects of early androgenization on the social interactions in mice. Results of Expt 1 indicated that neonatally testosterone propionate (TP) treated females, when mature, were attacked faster, more frequently, and for longer durations by trained fighters than females treated neonatally with oil. Experiment 2 showed that male castrates coated with urine from neonatally TP-treated females were attacked more often and for longer durations than castrates coated with urine from neonatally oil-treated females. The results implicated a urinary pathway of pheromonal output. Experiment 3 was conducted to investigate the relatively long-term social interactions between a naive male and a female treated at birth with TP or between a naive male and a female treated at birth with oil. The androgenized females showed a greater number of wounds after 5 days of pair housing than the control females. Five out of seven androgenized females were killed. Six control females gave birth, and none of the remaining two androgenized females did.
