Assessing the impact of civil gang injunctions on the use of online media by criminal street gangs
No full textMounting evidence suggests that members of criminal street gangs use internet communications technology to advertise their accomplishments, promote a counter-normative lifestyle, and continue illicit operations. Noting that not all content is equal in its ability to influence target audiences, this study investigates the message sensation value (MSV) of material posted by street gangs with civil gang injunctions. Gangs facing increased social censure and behavioral restrictions associated with the imposition of CGIs may be more inclined to post You Tube videos with high MSV to promote gang lifestyles and brand, as their visibility in the neighborhood may be diminished by law enforcement action. The results show that (1) there is a moderate association between indices measuring MSV and content (lifestyle and branding); (2) gangs that continue to use physical violence to maintain social dominance arc observed to have lower scores on MSV, lifestyle and branding metrics; and, (3) videos filmed in public settings and those produced by gangs that have been under injunction for a longer period are likely to have stronger branding messages, while videos filmed in a safe zone are expected to have lower lifestyle messages. We find no significant difference between video quality between the Bloods and the Crips

Strain OT2-17 demonstrated the use of triclosan as the sole carbon source. A genome assembly of approximately 5.8 Mb was generated with a calculated G+C content of 45.5%
A paradigm of safety management in Industry 4.0
No full textSafety management determines and implements safety policy. It is closely intertwined with industrial development. As the Fourth Industrial Revolution, Industry 4.0 presents new challenges and opportunities for safety management. The paper identifies three stages, namely, Safety 1.0, Safety 2.0 and Safety 3.0, for the evolution of safety management by considering safety principles, technologies and modes. A theoretical framework that integrates Safety 3.0 and Industry 4.0 is presented. Furthermore, knowledge graphs are developed with Citespace to explore the status of cross-topic research on safety management and Industry 4.0. Potential opportunities for integrating Safety 3.0 and Industry 4.0 are discussed

As such, this paper reviews Industry 4.0 and Industrial Internet and presents a case study about how Sany Heavy Industry applying systems thinking in implementing Industrial Internet and transforming itself into intelligent manufacturing. The growth path of intelligent manufacturing in Sany Heavy Industry is outlined. The directions for future development of intelligent manufacturing are discussed
A material delivery system built on Internet of Things and the role of libraries
No full textPurpose: After the occurrence of natural disasters, the rapid and accurate delivery of geo-afforestation is the key to emergency rescue and is the fundamental solution to the “last mile” problem. It provides technical support for the territorial rapid and accurate delivery. The paper aims to discuss this issue. Design/methodology/approach: Through literature and theoretical research, combined with the research experience of scholars, the qualitative research method is adopted. The paper establishes a three-dimensional analysis framework, including disaster predictability, resource availability and transport accessibility, and proposes the integrated delivery triangular technical framework, including integrated monitoring analysis, the territorial virtual public storage and transportation. Findings: Based on the analysis of the factors affecting the effectiveness of emergency delivery, the paper establishes a three-dimensional analysis framework, including disaster predictability, resource availability and transport accessibility, and proposes the integrated delivery triangular technical framework, including integrated monitoring analysis, the territorial virtual public storage and transportation. The triangular technical characteristics and functions of emergency delivery are studied, providing theoretical basis and technical support for effective rescue and emergency planning. Originality/value: The territorial emergency delivery refers to the process of rapid and accurate delivery without relying on external territorial supplies. The paper establishes a three-dimensional analysis framework, including disaster predictability, resource availability and transport accessibility, and proposes the integrated delivery triangular technical framework, including integrated monitoring analysis, the territorial virtual public storage and transportation
A P0–P0 weak Galerkin finite element method for solving singularly perturbed reaction–diffusion problems
No full textThis paper investigates the lowest-order weak Galerkin finite element (WGFE) method for solving reaction–diffusion equations with singular perturbations in two and three space dimensions. The system of linear equations for the new scheme is positive definite, and one might readily get the well-posedness of the system. Our numerical experiments confirmed our error analysis that our WGFE method of the lowest order could deliver numerical approximations of the order O(h1/2) and O(h) in H1 and L2 norms, respectively
Del texto al lienzo: El Quijote Ilustrado en el arte de Carnicero, Doré y Dalí
Full text linkLiterature and art are intrinsically linked. This thesis studies the connection between fiction and visual arts by looking at the written text and accompanying illustrations in Cervantes’ Don Quijote de la Mancha. These two ways of artistic expressions are interconnected and inform and influence each other over time. By applying the theory of intertextuality, the relationship between the two is analyzed and described. The link between text and illustration is also examined via the literary device of ekphrasis, however, in an inverted form. Both, literature and art, share the power of expression to tell stories that will continue to exist beyond time, space, and the cultures that created them. Many artists have had the honor of illustrating Don Quijote and have created an iconography of the novel that assists readers with the understanding of the written text. By studying some of the images created by Antonio Carnicero (1748-1814), Gustave Doré (1832-1883), and Salvador Dalí (1904-1989), this study finds that the illustrations also contribute additional readings and interpretations of the text that may change over time while adding new layers of intertextuality to the novel
Lo nacional y lo global en el desempeño de los medios durante la infodemia sobre COVID-19: El caso de Argentina
No full textEn el marco de la pandemia de la enfermedad COVID-19, organismos internacionales e investigadores denunciaron que la propagación de noticias “falsas” sobre la enfermedad y su combate tenía efectos epidémicos. Esto generó la propuesta de que las noticias y las redes de comunicación que proporcionan información sensible sobre la crisis sanitaria pudiesen considerarse como bienes públicos, con el objetivo de contrabalancear la denominada “infodemia”. En este artículo vamos a analizar críticamente esta propuesta, a partir de una evaluación normativa del rol de los medios de comunicación en el caso argentino, y realizando a tal efecto una encuesta de opinión pública sobre el desempeño de los medios y otros actores sociales durante la pandemia, cuyos resultados se presentan. En la conclusión se identifica una tensión entre las pretensiones de una información estandarizada global y las funciones de los medios en el marco nacional de las democracias, que se expresa tanto en el análisis conceptual como en las evaluaciones del público
Ecomorphological divergence and habitat lability in the context of robust patterns of modularity in the cichlid feeding apparatus
No full textBackground: Adaptive radiations are characterized by extreme and/or iterative phenotypic divergence; however, such variation does not accumulate evenly across an organism. Instead, it is often partitioned into sub-units, or modules, which can differentially respond to selection. While it is recognized that changing the pattern of modularity or the strength of covariation (integration) can influence the range or rate of morphological evolution, the relationship between shape variation and covariation remains unclear. For example, it is possible that rapid phenotypic change requires concomitant changes to the underlying covariance structure. Alternatively, repeated shifts between phenotypic states may be facilitated by a conserved covariance structure. Distinguishing between these scenarios will contribute to a better understanding of the factors that shape biodiversity. Here, we explore these questions using a diverse Lake Malawi cichlid species complex, Tropheops, that appears to partition habitat by depth. Results: We construct a phylogeny of Tropheops populations and use 3D geometric morphometrics to assess the shape of four bones involved in feeding (mandible, pharyngeal jaw, maxilla, pre-maxilla) in populations that inhabit deep versus shallow habitats. We next test numerous modularity hypotheses to understand whether fish at different depths are characterized by conserved or divergent patterns of modularity. We further examine rates of morphological evolution and disparity between habitats and among modules. Finally, we raise a single Tropheops species in environments mimicking deep or shallow habitats to discover whether plasticity can replicate the pattern of morphology, disparity, or modularity observed in natural populations. Conclusions: Our data support the hypothesis that conserved patterns of modularity permit the evolution of divergent morphologies and may facilitate the repeated transitions between habitats. In addition, we find the lab-reared populations replicate many trends in the natural populations, which suggests that plasticity may be an important force in initiating depth transitions, priming the feeding apparatus for evolutionary change
Character Evidence, Mediocrity, and Walter Scott’s Advocate-Narrator
No full textMany of Walter Scott’s fictional plots engage with serious crimes like treason and the violent acts involved in dueling. This article examines how Scott’s narrators draw on contemporary conventions for treating persons accused of such crimes in the criminal courtroom, considering especially how the characters and scenes of the Waverley Novels are constructed and described in ways that emphasize protagonists’ lack of agency. Essentially, Scott’s legally savvy narrators function like expert defense attorneys in their delivery of exculpatory character evidence on behalf of his “mediocre heroes.” Passive, unambitious, and drawn along by the plot, these heroes become a character type ideally suited for denying malice aforethought and evading responsibility
