Enzymatic hydrolysis of marine fish gelatin for producing ACE inhibitor peptides: meta-analysis
Authors: Ahmad Ahmad , Sukarno Sukarno , Slamet Budijanto , Sitanggang Azis Boing
Published: March 2023

Bioactive peptides showing Angiotensin-I-Converting Enzyme inhibitory (ACEi) activity can control blood pressure. They can be produced from various protein sources, including fish gelatin. This article provides a systematic review and meta-analysis on gelatin extraction, conditions of enzymatic hydrolysis, characteristics of ACEi peptides, and effect of hydrolysis procedure on ACEi peptides. Fish gelatin preparation uses various solutions such as acids, bases and distilled water. Enzymatic hydrolysis is carried out with an E/S ratio of 0.2 – 7% and temperature of 28.9 oC (using bromelain) and 60.6 oC (using Alcalase). Level of pH in hydrolysis also varied greatly, from 2 (using Pepsin) to 10 (using Purafect enzyme). The molecular weight of fish gelatin ACEi peptides ranged from 186-829 Da and the sequence of peptides was dominated by hydrophobic and aliphatic amino acids. Based on a meta-analysis, hydrolysis using enzyme combination resulted in more satisfying product than a single enzyme, represented with a combined effect size value of 0.593.
Gobernanza policéntrica en torno al cambio climático y la biodiversidad:
Authors: González Joel Hernán
Published: March 2023

La realidad ambiental actual está signada por múltiples desafíos y crisis que exigen respuestas. La crisis climática y la crisis de biodiversidad se encuentran entre las principales. El mecanismo REDD+ ha emergido en la Convención Marco de Naciones Unidas sobre Cambio Climático (CMNUCC) como un instrumento para abordar la problemática de las emisiones de carbono del sector forestal. Dada sus características y, el carácter policéntrico de la gobernanza ambiental global, el mecanismo despertó el interés de la Convención sobre Diversidad Biológica (CBD).

Partiendo de la necesidad de articular los instrumentos nacionales a la luz de lo trabajado en espacios internacionales como la CMNUCC y la CBD, el artículo se propone responder el siguiente interrogante ¿Cuál es el nivel de integración de la biodiversidad en los planes y estrategias REDD+ de los países sudamericanos? Para ello se observan 4 aspectos clave: la identificación y relevancia de los co-beneficios en materia de biodiversidad dentro de la estrategia REDD+; la vinculación de la estrategia REDD+ con la CBD y las Metas de Aichi; la articulación de la estrategia REDD+ con los instrumentos nacionales de biodiversidad y, finalmente; la incorporación de la biodiversidad en las acciones, metas y objetivos de las estrategias REDD+.

Se parte aquí de un enfoque metodológico cualitativo centrado en el análisis de documentos. Para ello se trabaja con las Estrategias Nacionales REDD+ de los países sudamericanos que suponen los casos de estudio.

Utilizando las metas propuestas por el ODS 17, se advirtió la necesidad de generar una herramienta para permitiera establecer los marcos de colaboración entre los diferentes actores para garantizar los objetivos de la política cultural de la administración local.
Gobierno militar y autodefensa:
Authors: Manzo Luciano
Published: March 2023

Etnicidad y conflicto han marcado la historia reciente birmana. Los sucesivos gobiernos militares que se hicieron con el poder sembraron división dentro de la sociedad al marginar a grandes sectores de la población que conforman las diversas minorías étnicas del país. Apoyándose en un concepto restrictivo de identidad nacional, las fuerzas armadas fueron limitando gradualmente el lugar de las comunidades minoritarias tanto en la política como en la sociedad.  La autodefensa mediante la formación de grupos armados étnicos fue vista como la única estrategia viable en pos de garantizar la vida y mínimos márgenes de libertad. El presente artículo desarrolla la relación entre el poder militar y la vida étnica en Myanmar. Se rastrea el origen histórico del conflicto pasando por una breve descripción del contexto multiétnico birmano. Trayendo elementos aportados por la filosofía de la violencia, se analiza en detalle la defensa de sí montada por los diferentes grupos étnicos y su relación con el valor asignado a la(s) diferentes vida(s) en el marco de la problemática. A raíz de los sucesos más recientes, se pone en discusión la posibilidad de un desenlace transformador que logre recomponer los vínculos dentro de la sociedad posibilitando una verdadera unión nacional.
territorialidades de la pobreza en la Argentina contemporánea:
Authors: Martínez Robles Claudia
Published: March 2023

El artículo expone los puntos de convergencia, desplazamientos y tensiones en las problematizaciones y prácticas que despliega cotidianamente el Estado nacional sobre los territorios blanco de sus intervenciones socio-asistenciales, entre el período 2008-2019, en Argentina. Para el análisis, seleccionamos dos políticas concretas de alcance nacional que se presentan a sí mismas como novedosas: El “Plan Ahí” y el “Estado en tu Barrio”. Desde un abordaje cualitativo, que articula técnicas de producción de datos heterogéneas, los programas son analizados como casos que permiten iluminar las racionalidades específicas que orientaron las intervenciones de gobierno entre los ciclos definidos como posneoliberalismo y retorno neoliberal, así como elucidar los procesos a través de los cuales los analizadores son constituidos, significados y reorientados. El articulo plantea que se produjeron algunas transformaciones en el modo de concebir y modular la relación Estado-territorios que muestran el pasaje de un esquema comunitario de recorte y configuración de los territorios empobrecidos hacia una lógica que reconfigura y aborda dichos espacios en términos de agregados de individuos singularizados.
La política de defensa argentina:
Authors: Ugarte José Manuel
Published: March 2023

La política de defensa argentina durante los últimos tres gobiernos evidencia la existencia de concepciones opuestas sobre la defensa, pero una consecuencia común: la imposibilidad de obtener para el país una capacidad de defensa razonablemente adecuada ante los riesgos existentes. A problemas estructurales que se arrastran desde décadas en materia de estructura de personal, bajo presupuesto y consiguientes limitaciones en materia de adiestramiento del personal y equipamiento, se suman la adopción de objetivos de política de defensa incompatibles entre sí, dispersión de esfuerzos y objetivos, y demoras para la adopción de decisiones. Medidas adecuadas como la creación del FONDEF se ven esterilizadas por su empleo en adquisiciones que no contribuyen a solucionar la crítica situación que en materia de equipamiento militar afronta el país.
Dictadura.
Authors: Portinaro Pier Paolo
Published: March 2023

En una época caracterizada por la tendencia a la creciente hibridación entre democracias y regímenes autoritarios (con la acuñación del neologismo “democradura”), y en la que, debido a la difusión de la cultura de la emergencia, ha vuelto a revivir el concepto de “democracia constitucional” (objeto de algunos estudios de la primera mitad del siglo XX), es necesario abrir dentro de la teoría política el debate sobre la dictadura. Partiendo de la distinción entre “dictadura comisarial” y “dictadura soberana” (tema de un clásico libro de Carl Schmitt), el artículo se centra en algunos pasajes destacados de la dictadura en la antigua Roma, en el proceso de formación del Estado moderno y en el pensamiento político de la tradición republicana, para concluir sobre los aspectos problemáticos del actual renacimiento del concepto.

GRAIN UNLOADING FROM UNIVERSAL SEMI-AUTOMATIC ROTARY DRYER
Authors: Николаев В.А.
Published: March 2023

Большие финансовые затраты на сушку обусловлены как дороговизной сушильно-сортировальных комплексов, так и ограниченным периодом их эксплуатации в течение года. Чтобы использовать сушилку в течение всего года, она должна быть универсальной, то есть качественно сушить без существенной переналадки все материалы и изделия сельскохозяйственного и подсобного производства. Так как конструкция предлагаемой полуавтоматической универсальной роторной сушилки имеет существенные отличия от сушилок, используемых в настоящее время, необходима разработка теории выгрузки зерна из неё. В результате анализа воздействия зерна на выгрузной транспортёр полуавтоматической роторной сушилки выявлен общий вращающий момент, необходимый для привода транспортёра выгрузки.

Large financial costs for drying are due to both the high cost of drying and sorting complexes, and the limited period of their operation during the year. In order to use the dryer throughout the year it must be universal, that is, it must dry reliably all materials and products of agricultural and subsidiary production without significant readjustment. Since the design of the proposed semi-automatic universal rotary dryer has significant differences from the dryers currently in use, it is necessary to develop a theory for unloading grain from it. As a result of the analysis of the grain effect on the unloading conveyor of the semi-automatic rotary dryer, the total torque required to drive the unloading conveyor was revealed.

The story of Peter Wilhelm Lund: between life and work
Authors: Schøllhammer Karl Erik
Published: March 2023

Anniversaries and commemorations often inspire us to tell stories about a person’s life as if it was the staging of a final scene – the achievement or frustration of ambition – a final scene that allows us to understand a person’s life as part of history, and history as if it was based on the life of its characters. In contemporary historiography it is recognized that history can never be reduced solely to a report about its heroes and that the life of a person rarely confounds itself only with a person’s work and ambitions.

The study of freshwater molluscs associated with helminth larval stages from the state of Rio de Janeiro revealed different morphological types of cercariae. Among them, Pleurolophocercus cercaria, Echinostomocercaria, Strigeocercaria, and Xiphidiocercaria, were found in Biomphalaria tenagophila (Orbigny, 1835), Physa marmorata Guilding, 1828 and Melanoides tuberculatus (Müller, 1774). For the later species is the first occurrence as an intermediate host for tremadodes in Brazil and the first record of Pleurolophocercus cercaria in Brazil.
The bamboo-nesting carpenter bee, Xylocopa (Stenoxylocopa) artifex Smith (Hymenoptera: Apidae), also nests in fibrous branches of Vellozia (Velloziaceae)
Authors: Silveira Fernando A.
Published: March 2023

Previous nest records and unusually modified mandibles of females have led workers to suggest that large carpenter bees (genus Xylocopa) in the subgenus Stenoxylocopa obligatory nest in bamboo and related plants with hollow stems. This paper reports the use of non-hollow substrate for nesting by one species in that subgenus. Nests found in the fibrous branches of Vellozia spp. (Velloziaceae) are described from two different sites. These nests are compared with those constructed in the hollow stems of bamboo that have been previously described. The data presented here do not support the hypothesis that geographical distributions of Stenoxylocopa are largely defined by the availability of hollow culms.
Bird species richness in natural forest patches in southeast Brazil
Authors: Andrade Renata D. , Marini Miguel Â.
Published: March 2023

Studies of populations in fragmented habitats have become essential tools in biodiversity conservation. This study was conducted at 14 natural forest patches (“capões”) in the Serra da Canastra National Park, with the purpose of evaluating bird species richness of these patches in relation to patch area and distance to other patches. In this study, area and isolation did not explain much of the variation in bird richness and abundance when all species were considered. However, when only forest-dependent species were considered, both area and isolation were significantly related to patch richness, suggesting that the distribution of these birds is highly related to forest patch area and is limited by dispersal ability of the species through the matrix. But, some individuals of some forest-dependent species (Thamnophilus caerulescens, and Basileuterus leucophrys) were also found in the very small (0.05 ha) or most isolated (430 to 700 m) patches. This fact may be related to an adaptation of these species to the naturally fragmented landscape, since this is a landscape which have not been altered considerably in the last two centuries. Our results showed that this natural landscape of small and isolated forest patches imbedded in a grassland matrix may support populations of several forest-dependent species of birds, increasing the regional biodiversity.

Altitudinal patterns in a tropical ant assemblage and variation in species richness between habitats
Authors: Araújo Luzia Márcia , Fernandes Geraldo Wilson
Published: March 2023

The distribution of ants along an altitudinal gradient from 800 m to 1500 m was studied in southeastern Brazil. Two hypotheses were tested: a) “the altitudinal gradient hypothesis”, which predicts that ant species richness decreases with increasing altitude; and b) “the habitat favourability hypothesis”, which predicts that ant species richness is higher in mesic habitats than in xeric habitats, independent of altitude. Pairs of mesic and xeric habitats were randomly established and replicated three times at each 100 m of elevation. Mesic habitats were those along washes, creeks and rivers while xeric habitats were those away from water resources. Ants were collected utilizing sardine baits distributed along transects on both vegetation and on soil. The species richness of ants collected on vegetation and soil increased with decreasing elevation. This pattern was found for ants collected on the ground in both mesic and xeric habitats. Also, we found more ant species in mesic habitats (0.64 ± 0.05 ants/sample set) than in xeric habitats (0.45 ± 0.05 ants/sample set)(t = 3.51, p < 0.001). The decreased number of ant species at higher elevations as well as in xeric habitats may be caused by a decrease in habitat complexity that limits the success of ants. Furthermore, at high altitudes harsher habitat conditions and lower temperatures prevail, further limiting the success and establishment of ants.

Preliminary sampling of Euglossina (Hymenoptera: Apidae: Apini) of Reserva Particular do Patrimônio Natural “Feliciano Miguel Abdala”, Caratinga, Minas Gerais, southeastern Brazil
Authors: Nemésio André
Published: March 2023

Male euglossine bees were attracted to and collected at seven chemical baits in two sites at different distances from the forest edge at the Reserva Particular do Patrimônio Natural “Feliciano Miguel Abdala”, Caratinga, Minas Gerais state, southeastern Brazil, a 957 ha remnant of the Atlantic Rain Forest. One hundred twentytwo individuals belonging to seven species were collected. Eulaema cingulata (Fabricius, 1804) was the most common species at both sites, followed by Euglossa despecta Moure, 1968. β-ionone was the most attractive bait in both sampling sites, followed by skatole. This study shows that further collections of euglossine bees at this site are needed.

Published: March 2023

Between 1999 and 2004 we recorded the whistling heron, Syrigma sibilatrix, in Goiás state, central Brazil.One specimen was collected and deposited in the Fundação Museu de Ornitologia de Goiânia (FMOG12855). Observations were conducted in some municipalities of the Goiânia metropolitan region and in thewest-central, northeastern and southern regions of Goiás. Probably, the range expansion of this species is dueto the increase of pastures, artificial ponds and other anthropic areas in the region. However, it may onlyreflect the paucity of ornithological studies in central Brazil.
Light and temperature influence on seed germination of Calliandra fasciculata Benth. (Leguminosae)
Authors: Fernandes Felipe , Fernandes Geraldo W.
Published: March 2023

The goal of this study was to verify the influence of light and temperature in the germination of seeds of Calliandra fasciculata (Leguminosae). Seeds were subjected to germination tests at the temperatures of 15, 25 and 35ºC under 12h-photoperiod and continuous dark for 30 days. Germination did not differ between the light and dark treatments at all temperatures tested (p > 0,05). The temperatures of 25 and 35ºC promoted higher germinability (F = 19,31; p < 0,001) when compared with the temperature of 15ºC. The mean time of germination was not influenced by photoperiod but was higher at 15ºC. High germinability values (> 70%) indicate lack of physical dormancy caused by tegument impermeability.

Unidentified species of Trichogrammatidae (Hymenoptera) and Spalangia sp. (Hymenoptera: Pteromalidae) were found parasitizing, eggs and nymphs of P. torridus, respectively.
Análise cladística dos caracteres de anatomia externa e esquelética de Apteronotidae (Teleostei: Gymnotyiformes)
Authors: Triques Mauro L.
Published: March 2023

Cladistic analysis of external morphology and skeletal characters was undertaken for 37 species of Apteronotidae, Neotropical electric fishes. Orthosternarchus + Sternarchorhamphus (included here in Sternarchorhamphinae status novo) are proposed to be the sister taxa to all remaining apteronotids, most of which form a basal polytomy in Apteronotinae. Several apteronotid species are currently incertae sedis but the monophyly of several genera were corroborated. Sternarchorhynchus is proposed to be the sister group of Ubidia magdalensis + Platyurosternarchus macrostomus, together forming the Sternarchorhynchini. Snout elongation was revealed to have occurred in several independent evolutionary lines as the Sternarchorhynchini, Orthosternarchus and Sternarchorhamphus. Apteronotus is restricted here to A. albifrons + A. jurubidae and postulated to be the sister group to Parapteronotus, which includes P. hasemani + P. macrostomus. “Apteronotus” leptorhynchus is postulated to be the sister group to “Apteronotus” cuchillo + Sternarchogiton cuchillejo and this three-species group is itself postulated to be the sister group of Apteronotus + Parapteronotus, and “Apteronotus” bonapartii postulated to be the sister group to “Apteronotus” apurensis. Autapomorphies were found for most of the species. A classification is presented for the family.

A ictiofauna do Parque Nacional da Serra do Cipó (Minas Gerais, Brasil) e áreas adjacentes
Authors: Vieira Fábio , Santos Gilmar B. , Alves Carlos Bernardo M.
Published: March 2023

The Espinhaço mountain chain is the water divisor of many river basins in Minas Gerais – Brazil. The Parque Nacional da Serra do Cipó (PNSC), located in the southern portion of this mountain chain, has a considerable drainage system, including headwaters of tributaries of both the São Francisco and the Doce river drainages. Fish sampling was conducted within the PNSC and adjacent areas, in both river basins, along an altitudinal gradient. Forty-eight fish species were recorded (17 in the Doce and 36 in the São Francisco basins), and only five species were captured in both basins. Fish species attaining small sizes as adults (<15 cm) represented approximately 60% of the total richness. Fish distribution was markedly influenced by altitudinal gradient, with only two species recorded in the highest altitudes. The greatest species richness was recorded in the lower areas, outside the PNSC. Although these areas have more species, the PNSC conserves an important portion of them, including an endangered species. Distribution, biology and conservation of local ichthyofauna are presented.
Notes on the taxonomy and distributions of the tufted capuchin monkeys (Cebus, Cebidae) of South America
Authors: Rylands Anthony B. , Kierulff M. Cecília M. , Mittermeier Russell A.
Published: March 2023

A good understanding (categorization) of the diversity and distribution of the tufted capuchin monkeys (Cebus) has proved to be extraordinarily intractable. Its lack is now hampering conservation efforts, for, despite them being, in general, wide-ranging and adaptable, their forests are being destroyed to the extent that many populations are now evidently seriously threatened. Conservation measures require that we know better their diversity not only to protect them in the wild but also to establish captive breeding programs. In this paper, we present some notes which resulted from our analysis of a recent published hypothesis regarding their systematics by C. P. Groves, in his influential synthesis Primate Taxonomy (2001). We are not presenting another hypothesis (taxonomy), but review aspects of some of the names and synonyms of Groves’ taxonomy, and briefly discuss its concordance with the results of a largely unpublished PhD thesis of tufted capuchin systematics completed by Cecília Torres de Assumpção in 1983.

The behavior of the predominant visiting bees Xylocopa (Neoxylocopa) cearensis Ducke 1910 and Centris (Centris) leprieuri Spinola 1841 was recorded with the aim of identifying their role as potential pollinators. The corolla is yellow, small, zigomorphic and homogamic. Anthesis is diurnal and longevity reaches ca 2 d (n=58); flowering synchrony is low (0.43) at the population level, resulting in a long flowering period. Mean nectar volume for first (2.13 ± 0.93 mL, n=27) and second day (0.96 ± 0.60 mL, n=26) flowers differed significantly (t=5.741, p<0.0001). Nectar concentration was lower in first day flowers (20%) than in second day flowers (26%), probably due to the reduction in volume caused by evaporation. Fruit formation was low in manual self-pollination (7%) and absent for spontaneous self-pollination. The highest percentage of fruit formation (89%) was found in control (natural conditions), suggesting that pollen vectors are important for the reproduction of C. brachiata. X cearensis and C. leprieuri collect nectar by landing on the four lower petals and introduicng their head into the corolla tube. Pollen adheres to the bee’s forehead at the same place that contact the reproductive structures of the flower. X. cearensis is the most efficient pollinator of C. brachiata, considering its local abundance, pattern of foraging activity, frequency of contact with reproductive structures and pollen transport.

Published: March 2023

Parasitic plants constitute an interesting study template for several botanical and ecological in the studies. In Brazil, about 100 species of Loranthaceae have been described, among which several in the genus Struthanthus, aerial hemiparasites characterized by an haustorial root system. We evaluated the host specificity of S. flexicaulis Mart. in a 9-ha area of high-altitude ironstone fields in the “Iron Quadrangle”, MG. The plant community develops over canga couraçada, a compact substrate rich in heavy metals, with low levels of moisture and organic matter. Of the 85 vascular plant species that occur in the area, 44, distributed among 19 families, are parasitized by S. flexicaulis, and one is used only as support. Phanerophytes were the most common host life-form. The lack of specificity is common to other Loranthaceae, and appropriate for a resource-heterogeneous environment, where host specificity would not be advantageous.
Ictiofauna do rio Carangola, bacia do rio Paraíba do Sul, no município de Carangola, Minas Gerais, Brasil
Authors: Melo Fabiana Cristina S. A. , Machado Adriana C. , Oliveira Ana Paula C. , Cruz Juliana M. , Latini Anderson O.
Published: March 2023

The Carangola River is one of the main components of the river Muriaé, which is the major tributary of the lower Paraíba do Sul. In the present study, sampling was carried out every three months during one year in three sites situated upstream the town of Carangola (Minas Gerais state, Brazil) and in three sites downstream. Twenty fish species, belonging to 17 genera and 12 families, were found — fifteen species upstream and 13 downstream the town. Diversity estimates (Shannon and inverse Berger-Parker indices), based on biomass and abundance, as well as physical-chemical parameters (turbidity, CO2 concentration and pH) did not differ between upstream and downstream sites. On the other hand, bacteriological parameters (fecal and total coliform counts) were significantly different between upstream and downstream sites. These differences, however, do not seem to be affecting the distribution patterns of the fish fauna, since no significant differences in faunistic composition were detected between the surveyed sites.
The bat communities (Chiroptera) of the Parque Estadual do Rio Doce, a large remnant of Atlantic Forest in southeastern Brazil

We surveyed the bat communities of a large Atlantic Forest reserve in the state of Minas Gerais, SE Brazil, the Parque Estadual do Rio Doce (PERD), over a period of ten months, collecting data on diet and reproduction of their bat species. We recorded bats using ground-level mist-nets erected in several environments within the park, and searched for bat roosts. Of a total of 33 species of bats recorded in the reserve to date, 24 bat species were recorded during this study,12 of which were first records for the park. Seeds of Cecropia predominated in the fecal samples of stenodermatine bats, and seeds of Piper were the main item in the fecal samples of Carollia perspicillata. We also got the first records of bats consuming fruits of Vismia magnoliifolia. Peaks of reproduction of bats in PERD occurred in the wet season, except for Desmodus rotundus, which was found reproductively active during the dry season. We suggest that the relative abundance of common species such as D. rotundus and Artibeus lituratus in the most disturbed areas within PERD may be correlated with distinct degrees of disturbance.
Euglossa decorata Smith (Hymenoptera: Apidae) in central Brazil – biogeographic implications
Authors: Nemésio André , Augusto Solange C. , Almeida Eduardo A. B.
Published: March 2023

Euglossa decorata Smith is currently regarded as endemic to the Amazon Basin. In the present study, a report is discussed of the presence of E. decorata in Uberlândia municipality, state of Minas Gerais, which is in the “Cerrado” or Brazilian savanna, and which extends the bee’s known geographic range over 2,000 km southwards. E. decorata either failed to respond to ancient vicariant events that caused speciation in other animal clades or expanded its range after geographical barriers ceased to exist between Amazonian and central Brazilian biogeographical components. This species may be endangered in the Uberlândia region, due to extensive habitat destruction.
Description of the downy chick of the slaty-breasted wood-rail Aramides saracura (Spix, 1825) (Aves: Rallidae)
Authors: Vasconcelos Marcelo F. , Hoffmann Diego , Palú Lauro
Published: March 2023

We describe the downy chick of Aramides saracura (Spix, 1825) based on individuals captured in the states of Rio Grande do Sul (3) and Minas Gerais (2), Brazil. The downy plumage is predominantly black, with the top of the head brownish. The egg tooth was present in two specimens. The downy chick of A. saracura differs from those of Aramides cajanea (Statius Müller, 1776) especially by the absence of rusty and brownish tones in their underparts.

Me río de la mafia. Los Cubrepileta y la sátira mafiosa en la Argentina
Authors: Favero Bettina Alejandra
Published: March 2023

In this essay, the mafia appears as a cultural object when analyzed from a humorous program broadcast in the 1990s in Argentina. It is Los Cubrepileta, a sketch that was part of Cha Cha Cha starring Alfredo Casero, Fabio Alberti, Diego Capusotto, Vivian El Jaber, Jorge Takashima, Alejandra Flechner, among others. Cha Cha Cha was a crazy, surreal and absurd program broadcast during 1993 and from 1995 to 1997 on América TV. Although the space was never massive, it is interesting to observe and analyze the way in which the sketch dedicated to an Italian family (Los Cubrepileta) parody the mafia with gags, jokes and set phrases inspired by movies and novels as well as the stereotype from the Italian mobster. To this is added another interesting fact, the reproduction of the sketches on YouTube, the visualizations and the comments on them.
¿Adónde se habrá metido Mafiopoli? Las mafias italianas según La Gente d’Italia
Authors: Smeriglio Gabriele Paolo
Published: March 2023

Generalisations can never tend to be exhaustive, nor can they claim to represent all subjectivities and the diverse and consequent political-ideological narratives that are part of them. But they also describe social and behavioural propensities present in the cultural folds of a specific social group. The role of newspapers, sounding boards for certain ethnic, political, economic and social sentiments, is fundamental to study the rapid consumption of these communicative processes whose contents end up being internalised even before they are processed. Beyond the level of scientific substance of which they are composed. In relation to the treatment of Italian mafias in the press, this manuscript aims to analyse, based on a selection of articles published between 2018 and 2022, the narratives produced by “La Gente d’Italia”, an Italian-language ethnic newspaper based in Uruguay, on the combination between persistence and change, between maintaining consolidated structures and adapting to the changes in the economic and social context in which the mafia is present today.
La Mafia e l’agire sociale delle donne
Authors: Gammaitoni Milena
Published: March 2023

The article presents a historical-social excursus on the criminality of women and on the stereotypes and prejudices that have long obscured a real understanding of the phenomenon: in the history of ideas, in medicine, in jurisprudence, in the media and in the various social representations. Analyzing their different roles, from the socialization of children to the mafia mentality, but also the central role of some women in the rebellion against the mafia, is a necessary path for a deeper reflection of the phenomenon.
مظاهر الحب من وجهة نظر ملاصدرا والإمام الخميني (ره)
Authors: حسيني مهناز , بختيار مريم
Published: March 2023

الحب هو واحد من أهم الركائز الأساسية و ربما أهم عنصر في التفكير التصوف الإسلامي. الحب بأيِّ شكلٍ و لونٍ، مقدّسٌ لمجموعة من الصوفيين. ليس الحب الحقيقي فقط هو حب العاشق الحقيقي، و لكن أيضاً الحب الإفتراضي المقدس بالنسبة لهم. هذا هو السبب في أنّ الصوفيين لم يرفضوا الحبَّ الظاهري تماماً و قد تعامل معه أناس عظماء مثل ملاصدرا شيرازي و الإمام الخميني بطرق مختلفة. اعتبر صدر المتألهين الشيرازي، بناءً على مبادئه الوجودية في الحكمة السامية، الحبّ مساوياً للوجود و اعتبره جارياً من حيث مستويات الوجود في جميع جزيئات العالم. يعتبرُ الحبَّ طريق الوجود البشري و إجدي المدخلات الإلهية في الطبيعة البشرية و يعتبره مليئاً بالحكمة و المصلحة. يبدو أنّ الإمام الخميني (ره) استخدم أيضا أفكار ابن عربي و ملاصدرا، و يعتزم تقديم تفسير صوفي شيعي لفئة الحب، و الحب البشري و الإلهي مع ميل الشيعة الإماميين و الإنتباه إلى التصوف العملي و حتى أمثلة على البشر المثاليين، أن يكون أكثر انسجاماً مع واقع الوجود الموضوعي. بالإضافة إلى ذلك، يحاول كلاهما امتلاك المحتوى الخاص بهما في مقاربتهما لموضوع «حب» المعايير الدينية، في تفسيرهما الصوفي و الفلسفي. يرتبط موضوع الحب بشكل عام، في الفلسفة و النهج الغامض لملاصدرا و الإمام الخميني ارتباطاً وثيقاً ببعضهما البعض و على الرغم من بعض الإختلافات الواضحة بين فلاسفة الحب، فقد أقاما علاقة لا يمكن فصلها و حكما على مظاهر الحب و الحب الحقيقي و الله. في هذا المقال، أثناء فحص مظاهر الحب و الجمال و علاقته بالله في سيرة كل من الصوفيين العظيمين في العالم الشيعي، نقارن بين هذين الرأيين لكشف الاختلافات و التشابهات بين هذين الرأيين
