Community detection is crucial for applications like targeted marketing and recommendation systems. Traditional methods rely on network structure, and embedding-based models integrate semantic information. However, there is a challenge when a model leverages local and global information from complex structures like social networks. Graph Neural Networks (GNNs) and Transformers have shown superior performance in capturing local and global relationships. In this paper, We propose Graph Integrated Transformer for Community Detection (GIT-CD), a hybrid model combining GNNs and Transformer-based attention mechanisms to enhance community detection in social networks. Specifically, the GNN module captures local graph structures, while the Transformer module models long-range dependencies. A self-optimizing clustering module refines community assignments using K-Means, silhouette loss, and KL divergence minimization. Experimental results on benchmark datasets show that GIT-CD outperforms state-of-the-art models, making it a robust approach for detecting meaningful communities in complex social networks.
Since the early 2010s, social network-based influence technologies have grown almost exponentially. Initiated by the U.S. Army's early OEV system in 2011, a number of companies specializing in this field have emerged. The most (in)famous cases are Bell Pottinger, Cambridge Analytica, Aggregate-IQ and, more recently, Team Jorge. In this paper, we consider the use-case of sock puppet master activities, which consist in creating hundreds or even thousands of avatars, in organizing them into communities and implement influence operations. On-purpose software is used to automate these operations (e.g. Ripon software, AIMS) and organize these avatar populations into communities. The aim is to organize targeted and directed influence communication to rather large communities (influence targets). The goal of the present research work is to show how these community management techniques (social networks) can also be used to communicate/disseminate relatively large volumes (up to a few tens of Mb) of multi-level encrypted information to a limited number of actors. To a certain extent, this can be compared to a Dark Post-type function, with a number of much more powerful potentialities. As a consequence, the concept of communication has been totally redefined and disrupted, so that eavesdropping, interception and jamming operations no longer make sense.
El artículo analiza cómo un sector del radicalismo de San Francisco (Córdoba) integró en una sola identidad repudiable al comunismo y al fascismo para desprestigiar al intendente, también radical, Serafín Trigueros de Godoy durante 1932-1936. Desde una mirada local se busca contribuir a la comprensión del impacto que tuvieron en Argentina las polarizaciones ideológicas internacionales. En particular, cómo y por qué fue posible para un sector del radicalismo combinar discursos circulantes aparentemente antagónicos como el anticomunista y el antifascista. También, cómo impactó la orientación frentepopulista del Partido Comunista en una localidad donde este tenía una relevante inserción social.

The dominance of online social media data as a source of population-scale social network studies has recently been challenged by networks constructed from government-curated register data. In this paper, we investigate how the two compare, focusing on aggregations of the Dutch online social network (OSN) Hyves and a register-based social network (RSN) of the Netherlands. First and foremost, we find that the connectivity of the two population-scale networks is strikingly similar, especially between closeby municipalities, with more long-distance ties captured by the OSN. This result holds when correcting for population density and geographical distance, notwithstanding that these two patterns appear to be the main drivers of connectivity. Second, we show that the community structure of neither network follows strict administrative geographical delineations (e.g., provinces). Instead, communities appear to either center around large metropolitan areas or, outside of the country's most urbanized area, are comprised of large blocks of interdependent municipalities. Interestingly, beyond population and distance-related patterns, communities also highlight the persistence of deeply rooted historical and sociocultural communities based on religion. The results of this study suggest that both online social networks and register-based social networks are valuable resources for insights into the social network structure of an entire population.
Most modern agent-based evacuation models involve interactions between evacuees. However, the assumed reasons for interactions and portrayal of them may be overly simple. Research from social psychology suggests that people interact and communicate with one another when evacuating and evacuee response is impacted by the way information is communicated. Thus, we conducted a systematic review of agent-based evacuation models to identify 1) how social interactions and communication approaches between agents are simulated, and 2) what key variables related to evacuation are addressed in these models. We searched Web of Science and ScienceDirect to identify articles that simulated information exchange between agents during evacuations, and social behaviour during evacuations. From the final 70 included articles, we categorised eight types of social interaction that increased in social complexity from collision avoidance to social influence based on strength of social connections with other agents. In the 17 models which simulated communication, we categorised four ways that agents communicate information: spatially through information trails or radii around agents, via social networks and via external communication. Finally, the variables either manipulated or measured in the models were categorised into the following groups: environmental condition, personal attributes of the agents, procedure, and source of information. We discuss promising directions for agent-based evacuation models to capture the effects of communication and group dynamics on evacuee behaviour. Moreover, we demonstrate how communication and group dynamics may impact the variables commonly used in agent-based evacuation models.
Abstract Early socialism from the second half of 19th century Romania is experiencing a systematic comeback among historians and social scientists. The works of Constantin Dobrogeanu-Gherea, the founding father of Romanian Marxism, occupy a central place in this newfound attention towards the origins and struggles of socialism in Romania. This paper addresses Gherea’s interpretation of anarchism on par with his doctrine of ‘legal socialism’. Its purpose is to prove how anarchism acts as a more than tactical catalyzer for legal socialism, placing the latter not necessarily on a new ideological perspective, but further on the terrain of Romanian political status-quo of late 19th and early 20th century Romania. Although more principled than tactical, Gherea’s repudiation of anarchism in progressively unsubstantial Marxist terms has also led to tactical shortcomings. This was the case of the first Romanian socialist party, which was dissolved and absorbed after only six years of existence within the ascending liberal party.
Virgil Gheorghiu, an important but controversial figure in Romanian exile literature, remains one of his country’s best-known writers today. Based on his works and their reception, but also on the existing secondary literature, this study examines his reflection on three important ideologies, namely communism, national socialism and capitalism, in order to highlight the specificities of Virgil Gheorghiu’s thought and to see what aspects of topicality and contemporary relevance can be found in it.
Este artículo propone el dispositivo crítico “ciclo de las costureritas” como un modo de leer el trabajo “desde el género”. En tanto articulación entre literatura y vida, opera ante la “división sexual del trabajo”, productora de la escisión de esferas –pública/privada– y trabajos –productivo/reproductivo– según sexo-género. Fundado por la poesía “La costurerita que dio aquel mal paso”, de Evaristo Carriego (1913), este ciclo desborda hacia otras décadas, pero en los 20 y 30 adquiere inflexiones en la literatura, letras de tango, fotografías y películas que producen desvíos, alianzas e interrogaciones sobre los desplazamientos de las mujeres por lo público.

ABSTRACT This dialogue begins with the question of “concrete Marxism,” which is at the foundations of “Socialism with Chinese Characteristics.” The concrete is analysed in terms of Marx’s dialectic between freedom and necessity, as also in Marx’s early work on Epicurean materialism and in Engels’s “Dialectics of Nature” and “Anti-Dühring.” We include a discussion of Hegel’s dialectic between the actual and the rational. Subsequently, we move to the relationship of socialist construction to the (non-socialist) past and a socialist future. We adduce examples from Marx’s “The Eighteenth Brumaire of Louis Bonaparte,” as well as the Chinese concept of mingyun (destiny/future) and explore the implications of Lenin’s critique of “left wing” impatience with the past. The issue here is the mistake of a “leftist” effort to make the leap—through sheer voluntary effort—into communism as an over-compensation for practical deficiencies and, on the other hand, the possibility for revolutionary socialism of appropriating and transforming the positive advances of bourgeois culture and civilisation. We conclude with some preliminary observations on the communist prospect, emphasising the concrete form of the dialectic of productive forces and relations of production and the reasons why this form highlights the importance of the former as a motive force.
En el presente artículo se discute la denominación “socialismo romántico”, utilizada por Horacio Tarcus en una trilogía, publicada entre 2016 y 2020, que trata sobre la recepción de las ideas socialistas en la Argentina en el siglo XIX. Se realiza también una discusión acerca del socialismo anterior a Marx y su vínculo complejo con el romanticismo como movimiento literario o como filosofía de la historia.

Arbeiderbevegelsen grunnlagt av Marcus Thrane rundt 1850 fikk mange tilhengere i øvre Hallingdal fordelt på fem lag. Litt over halvparten av medlemmene var bønder, vesentlig småbønder fra tidligere husmannsplasser eller fra gardparter skilt ut fra større bruk. De øvrige var husmenn eller andre småkårsfolk. Etter «Lilletinget» sommeren 1851 ble lensmennene pliktige til å sende inn lister over medlemmene i arbeiderforeningene. En gjennomgang og analyse av listene gjorde det mulig å finne fram til slekt og andre forbindelser mellom medlemmene. Sammen med lokal kunnskap om bevegelsen til Hans Nielsen Hauge, ble det tydelig at i øvre Hallingdal ble Thranebevegelsen oppfattet som en videreføring av bevegelsen til Hauge, mest sannsynlig på grunn av næringspolitikken hans.
En vesentlig årsak til dette var at hattemaker Hallsten Knudsen, thraneorganisatoren fra naboregionen Ringerike, fikk sin oppvekst og utdannelse i et sterkt haugianermiljø som igjen hadde nære forbindelser med sentrale haugianerslekter i de nåværende kommunene Ål og Hol. Agitasjonen til Thranebevegelsen og spor etter bevegelsen i øvre Hallingdal viser at den gikk pragmatisk fram med sosialdemokratiske holdninger til eiendomsrett og sosiale forbedringer. Det gjaldt å få størst mulig oppslutning med tanke på å vinne fram til politiske resultater gjennom parlamentariske kanaler som regjering og storting.

Our social interactions mainly depend on the social phenomenon called trust. We evaluate our trust in our peer to decide whether to start an interaction or not. When our information about the peer is not sufficient, we use the knowledge of others. This knowledge can also be referred to as the reputation of the peer in the community. Like real-life communities, trust and reputation play a key role in virtual communities, too. These two notions help us overcome the complex interactions between agents in virtual communities. In previous studies regarding this topic, the social aspect of trust and reputation is partly ignored. In this paper, we will review an article which we accept as a starting point and compare it with another article that provides a more advanced model. Additionally, a new trust model which is mainly based on sociological notions will also be introduced.
Este artículo estudia la “gran huelga” que tuvo lugar en la ciudad de Rosario, Argentina, en agosto de 1896. Declarada en solidaridad con los ferroviarios de Tolosa, se transformó en general por la adhesión de todas las sociedades sindicales de la ciudad. Se reconstruye el episodio, se analiza la actuación de los protagonistas y la acción del Estado, proponiendo una interpretación centrada en las peculiaridades del contexto social y político en el que ocurrió.

El presente trabajo indaga el carácter contradictorio que asumió la convergencia de los diversos proyectos de reconstrucción de la sociedad luego de la Revolución Rusa de 1917. Se argumentará que los consensos entre Partido Bolchevique y movimiento obrero, relativos al fortalecimiento de una instancia estatal centralizada capaz de desenvolver una planificación global, se desarrollaron en conflictiva interacción con su contracara programática de asimilación de la llamada organización científica de trabajo.
