Authors: Sapienza Marco , Di Via Danilo , Vaccalluzzo Marco Simone , Costarella Luciano , Pavone Vito , Testa Gianluca
Published: May 2024

This retrospective cohort study assesses the effectiveness of straight-stem cementless versus cemented prostheses in hip replacement surgeries for elderly patients with femoral neck fractures. We analyzed 80 patients aged 70 and over who underwent surgery between 2018 and 2021. Clinical outcomes were evaluated using the Harris Hip Score, WOMAC Score, and Visual Analogue Scale, alongside radiological assessments through Brooker’s classification. Preoperative Dorr classification and five postoperative criteria (subsidence, cortical hypertrophy, pedestal sign, radiolucent lines, and stress shielding) were used to assess implant efficacy. The results demonstrated satisfactory mid-term outcomes for both groups, with slightly higher clinical scores observed in the cementless stem group. The Harris Hip Score (HHS) averaged 74.4 ± 6.7 in the cemented group and 79.2 ± 10.4 in the cementless group, with a statistically significant difference (p = 0.0146). The WOMAC Score showed an average of 30.1 ± 4.6 in the cemented group compared to 27.1 ± 6.9 in the cementless group, also indicating a statistically significant improvement (p = 0.0231). However, radiographic findings call for a re-evaluation of long-term stability. Our statistical analysis, which included power calculation and multivariate analysis to adjust for confounding variables, offers a comprehensive assessment of implant effectiveness. The findings contribute to the ongoing debate on the choice between cemented and cementless prostheses, indicating that both are viable options catering to different patient needs. Further research overcoming this study’s limitations is crucial for a deeper understanding of optimal treatment strategies in hip replacement surgery for the elderly.

Published: May 2024

Background: This study aimed to compare the clinical outcomes of using two different devices to treat upper palatal discrepancies evaluated with a digital intraoral scanner. Methods: A total of 64 patients were enrolled and treated with either an elastodontic expansion device (32 patient test group, 16 females and 16 males, mean age 7.08 ± 0.44) or Haas expander (32 patient control group, 16 females and 16 males, mean age 7.32 ± 0.50). The two groups exhibited similar orthodontic features. The orthodontic criteria were: skeletal class I relationship; molar class I relationship; complete eruption of upper sixths; presence of unilateral or bilateral cross bite. All dental casts were examined and subsequently scanned with an intraoral scanner (I-Tero) pre-treatment (T0) and 12 months after the onset of therapy (T1) to assess the distance between the decidous upper canines (ICW, intercanine width) and the distance between the mesiopalatal cusps of the upper first molars (IMW, intermolar width). For statistical analysis, the t-test for continous variables and the chi-square test for categorical variables were used, respectively. Results: There were no statistically significant differences between the mean and SD of the expansions that resulted from the Haas expander and the elastodontic devices (Haas expander vs. Eptamed: ICW_T1 (Haas) = 42.34 (3.09), ICW_T1 (Eptamed) = 42.69 (2.77); p = 0.743; IMW_T1 (Haas) = 34.22 (2.29), IMW_T1 (Eptamed) = 34.00 (2.56); p = 0.800). The two devices were similarly effective. Conclusions: Elastodontic devices and the Haas expander can successfully help the orthodontist to conduct upper arch expansion treatment. However, elastodontic devices are more comfortable during the resolution of palatal discrepancies compared to palatal expander devices.
Energy-Efficient and Highly Reliable Geographic Routing Based on Link Detection and Node Collaborative Scheduling in WSN
Authors: Wang Minghua , Zhu Ziyan , Wang Yan , Xie Shujing
Published: May 2024

Energy efficiency and data reliability are important indicators to measure network performance in wireless sensor networks. In existing research schemes of routing protocols, the impact of node coverage on the network is often ignored, and the possibility that multiple sensor nodes may sense the same spatial point is not taken into account, which results in a waste of network resources, especially in large-scale networks. Apart from that, the blindness of geographic routing in data transmission has been troubling researchers, which means that the nodes are unable to determine the validity of data transmission. In order to solve the above problems, this paper innovatively combines the routing protocol with the coverage control technique and proposes the node collaborative scheduling algorithm, which fully considers the correlation characteristics between sensor nodes to reduce the number of active working nodes and the number of packets generated, to further reduce energy consumption and network delay and improve packet delivery rate. In order to solve the problem of unreliability of geographic routing, a highly reliable link detection and repair scheme is proposed to check the communication link status and repair the invalid link, which can greatly improve the packet delivery rate and throughput of the network, and has good robustness. A large number of experiments demonstrate the effectiveness and superiority of our proposed scheme and algorithm.

Authors: Khan Irfanullah , Zedadra Ouarda , Guerrieri Antonio , Spezzano Giandomenico
Published: May 2024

In today’s world, a significant amount of global energy is used in buildings. Unfortunately, a lot of this energy is wasted, because electrical appliances are not used properly or efficiently. One way to reduce this waste is by detecting, learning, and predicting when people are present in buildings. To do this, buildings need to become “smart” and “cognitive” and use modern technologies to sense when and how people are occupying the buildings. By leveraging this information, buildings can make smart decisions based on recently developed methods. In this paper, we provide a comprehensive overview of recent advancements in Internet of Things (IoT) technologies that have been designed and used for the monitoring of indoor environmental conditions within buildings. Using these technologies is crucial to gathering data about the indoor environment and determining the number and presence of occupants. Furthermore, this paper critically examines both the strengths and limitations of each technology in predicting occupant behavior. In addition, it explores different methods for processing these data and making future occupancy predictions. Moreover, we highlight some challenges, such as determining the optimal number and location of sensors and radars, and provide a detailed explanation and insights into these challenges. Furthermore, the paper explores possible future directions, including the security of occupants’ data and the promotion of energy-efficient practices such as localizing occupants and monitoring their activities within a building. With respect to other survey works on similar topics, our work aims to both cover recent sensory approaches and review methods used in the literature for estimating occupancy.
Effect of a Chitosan-Based Packaging Material on the Domestic Storage of “Ready-to-Cook” Meat Products: Evaluation of Biogenic Amines Production, Phthalates Migration, and In Vitro Antimicrobic Activity’s Impact on Aspergillus Niger

Published: May 2024

The consumption of “ready-to-cook” foods has been experiencing rapid expansion due to modern lifestyles, and they are often sold in economical multipacks. These foods necessitate packaging that maintains their quality for extended periods of time during home storage once the original packaging is opened. This study evaluates a chitosan-based film derived from low- and high-molecular-weight (MW) chitosan in acetic acid without synthetic additives as an alternative packaging material for “ready-to-cook” beef burgers. The burgers were stored at 8 °C after being removed from their sales packaging. A commercial polyethylene (PE) film designed for food use, devoid of polyvinylchloride (PVC) and additives, served as the reference material. The production of six biogenic amines (BAs), indicative of putrefactive processes, was monitored. Additionally, the release of four phthalates (PAEs), unintentionally present in the packaging films, was assessed using solid-phase microextraction coupled with gas chromatography/mass spectrometry (SPME-GC/MS). Microbiological tests were conducted to investigate the antimicrobial efficacy of the packaging against Aspergillus Niger NRR3112. The results showed that the chitosan-based films, particularly those with low MW (LMW), exhibited superior meat preservation compared to the PE films. Furthermore, they released PAEs below legal limits and demonstrated the complete inhibition of fungal growth. These findings highlight the potential of chitosan-based packaging as a viable and effective option for extending the shelf-life and maintaining the quality of “ready-to-cook” meat products during domestic storage.
Breast Glandular and Ductal Volume Changes during the Menstrual Cycle: A Study in 48 Breasts Using Ultralow-Frequency Transmitted Ultrasound Tomography/Volography
Authors: Wiskin James , Klock John , Love Susan
Published: May 2024

The aim of this study was to show for the first time that low-frequency 3D-transmitted ultrasound tomography (3D UT, volography) can differentiate breast tissue types using tissue properties, accurately measure glandular and ductal volumes in vivo, and measure variation over time. Data were collected for 400 QT breast scans on 24 women (ages 18–71), including four (4) postmenopausal subjects, 6–10 times over 2+ months of observation. The date of onset of menopause was noted, and the cases were further subdivided into three (3) classes: pre-, post-, and peri-menopausal. The ducts and glands were segmented using breast speed of sound, attenuation, and reflectivity images and followed over several menstrual cycles. The coefficient of variation (CoV) for glandular tissue in premenopausal women was significantly larger than for postmenopausal women, whereas this is not true for the ductal CoV. The glandular standard deviation (SD) is significantly larger in premenopausal women vs. postmenopausal women, whereas this is not true for ductal tissue. We conclude that ducts do not appreciably change over the menstrual cycle in either pre- or post-menopausal subjects, whereas glands change significantly over the cycle in pre-menopausal women, and 3D UT can differentiate ducts from glands in vivo.

Published: May 2024

Objective: To determine the added value of digital breast tomosynthesis (DBT) in the assessment of lesions detected by contrast-enhanced mammography (CEM). Material and methods: A retrospective study was conducted in a tertiary university medical center. All CEM studies including DBT performed between January 2016 and December 2020 were included. Lesions were categorized and scored by four dedicated breast radiologists according to the recent CEM and DBT supplements to the Breast Imaging Reporting and Data System (BIRADS) lexicon. Changes in the BIRADS score of CEM-detected lesions with the addition of DBT were evaluated according to the pathology results and 1-year follow-up imaging study. Results: BIRADS scores of CEM-detected lesions were upgraded toward the lesion’s pathology with the addition of DBT (p > 0.0001), overall and for each reader. The difference in BIRADS scores before and after the addition of DBT was more significant for readers who were less experienced. The reason for changes in the BIRADS score was better lesion margin visibility. The main BIRADS descriptors applied in the malignant lesions were spiculations, calcifications, architectural distortion, and sharp or obscured margins. Conclusions: The addition of DBT to CEM provides valuable information on the enhancing lesion, leading to a more accurate BIRADS score.
Impacts of Weather Variability on the International Tourism Receipts—Evidence from Ethiopia (1995–2019)
Authors: Gebbisa Mesfin Bekele , Yasin Abdi Shukri , Bacsi Zsuzsanna
Published: May 2024

Every economic sector is susceptible to the direct or indirect effects of weather variability, and the tourism sector is no exception. In fact, the tourism industry is considered to be more vulnerable to the effects of weather variability than the general economy, with changes in weather patterns, extreme events, and environmental degradation offering substantial obstacles. Ethiopia’s tourism industry, like many others, faces challenges from weather variability. This study investigates the short- and long-term effects of weather variability on Ethiopia’s international tourism receipts. Utilizing data from 1995 to 2019, the research employs a vector error correction model to analyze the relationships between weather variables (temperature, rainfall), economic factors (GDP growth, inflation), political stability, and tourist arrivals. The findings reveal that in the long run, higher temperatures, rainfall, and inflation have negative impacts on tourism receipts, while political stability and past tourist arrivals have positive effects. Short-term trends mirror these, with the addition of GDP growth not showing a significant impact. To ensure the sustainability of tourism in Ethiopia, the study emphasizes the importance of understanding weather’s influence, developing adaptation strategies, and promoting sustainable tourism practices.

Urticaria, independent of or associated with allergies, is commonly seen in horses and often shows a high reoccurrence rate. Managing these horses is discouraging, and efficient treatment options are lacking. Due to an incidental finding in a study on horses affected by insect bite hypersensitivity using the eosinophil-targeting eIL-5-CuMV-TT vaccine, we observed the prevention of reoccurring seasonal urticaria in four subsequent years with re-vaccination. In an exploratory case series of horses affected with non-seasonal urticaria, we aimed to investigate the role of eosinophils in urticaria. Skin punch biopsies for histology and qPCR of eosinophil associated genes were performed. Further, two severe, non-seasonal, recurrent urticaria-affected horses were vaccinated using eIL-5-CuMV-TT, and urticaria flare-up was followed up with re-vaccination for several years. Eotaxin-2, eotaxin-3, IL-5, CCR5, and CXCL10 showed high sensitivity and specificity for urticarial lesions, while eosinophils were present in 50% of histological tissue sections. The eIL-5-CuMV-TT vaccine reduced eosinophil counts in blood, cleared clinical signs of urticaria, and even prevented new episodes of urticaria in horses with non-seasonal recurrent urticaria. This indicates that eosinophils play a leading role in urticaria in horses, and targeting eosinophils offers an attractive new treatment option, replacing the use of corticosteroids.

Authors: Wang Xinyu , Ye Xiao , Zhou Yipeng , Li Cong
Published: May 2024

In order to reduce the lateral error of path-following control of unmanned vehicles under variable curvature paths, we propose a path-following control strategy for unmanned vehicles based on optimal preview time model predictive control (OP-MPC). The strategy includes the longitudinal speed limit, the optimal preview time surface, and the model predictive control (MPC)controller. The longitudinal speed limit controls speed to prevent vehicle rollover and sideslip. The optimal preview time surface adjusts the preview time according to the vehicle speed and path curvature. The preview point determined by the preview time is used as the reference waypoint of OP-MPC controller. Finally, the effectiveness of the strategy was verified through simulation and with the real unmanned vehicle. The maximum lateral deviation obtained by the OP-MPC controller was reduced from 0.522 m to 0.145 m under the simulation compared with an MPC controller. The maximum lateral deviation obtained by the OP-MPC controller was reduced from 0.5185 m to 0.2298 m under the real unmanned vehicle compared with the MPC controller.

In this research, agriculture residues as reinforcement and filler were utilized for an epoxy-based matrix material. Glass fibre was incorporated in this composite throughout the production process in addition to the kenaf fibre. Rice husk ash filler in the matrix was maintained at 10 wt %, while the kenaf/glass hybrid fibre varied from 0 to 40%. Compression moulding was used to create the hybrid to study its mechanical attributes, which includes tensile strength, flexural strength, and impact strength. The results showed that due to the wettability of the given hybrid matrix, it exhibits superior mechanical characteristics. For 30% hybrid fibre and 10% filler material, the mechanical properties like tensile strength, flexural strength, and impact strength were raised by 41.26%, 14.42%, and 63.15%, respectively.

Published: May 2024

Objective. To analyze the levels of antioxidant enzyme superoxide dismutase (SOD) and glutathione peroxidase (GP) against the background of diabetic ketoacidosis (DKA) in type 1 diabetes mellitus (DM) children and adolescents. Materials and methods. The study involved examination of 74 children: 50 DKA children (study group) and 24 relatively healthy children (control group). The study group children were divided into two subgroups: subgroup 1 included children with DKA against the background of type 1 DM onset (n=27), subgroup 2 consisted of children with DKA against the background of chronic type 1 DM (n=23). SOD and GP concentrations in blood plasma were determined in all children by enzyme immunoassay. The reliability between the data was estimated using the Mann-Whitney test, Kruskal-Wallis test and Spearman coefficient. Results. A significant decrease in SOD and GP in children with DKA was revealed as follows: 13130 [13005–18255] Pg/ml and 50.085 [42.02–70.325] Ng/ml, compared to controls: 16415 [13370–19935] Pg/ml and 84.695 [52.49–144.5] Ng/ml, respectively. Minimal SOD and GP were noted in patients with DKA at the background of chronic type 1 DM, compared to DM onset children. The study indicates a reliable correlation between age, duration of the disease, number of DKA in the history and low values of SOD and GP. Conclusion. Decreased antioxidant capacity was found in children with DKA in type 1 DM. SOD and GP can be considered in pediatric practice as markers of oxidative stress in DKA. In addition, an early detection of SOD and GP contributes to the efficient therapy of DKA in children and adolescents.

Published: May 2024

Recurrent abdominal pain in childhood and adolescence may be indicative of chronic mesenteric ischemia with median arcuate ligament syndrome as a result of compression of the celiac artery by the median arcuate ligament of the diaphragm and its internal crura, neurofibrous tissue of the celiac plexus. The presence of symptoms characteristic of various diseases of gastrointestinal tract organs, absence of pathognomonic signs and complex approach in diagnostics of abdominal cavity vascular system, insufficient awareness of specialists of children’s outpatient clinics determine the urgency of timely diagnostics and treatment of patients with this pathology. Median arcuate ligament syndrome, or Dunbar syndrome, is more often a congenital malformation. This syndrome can be considered as an acquired pathology in the case of compression of the celiac artery by enlarged lymph nodes and neurofibrous tissue of the celiac plexus. In addition to hemodynamically significant disorders of blood supply to the gastrointestinal tract, Dunbar syndrome in children and adolescents is also accompanied by psycho-emotional disorders due to the presence of unstable stools, recurrent abdominal pain, and often repeated ineffective requests for medical care. Clinical observation, methods of diagnosis and surgical treatment of median arcuate ligament syndrome in a 14-year-old patient are presented in the study.

Artificial intelligence and the problem of media content prioritization
Authors: Shesterin N. O.
Published: May 2024

The development of artificial intelligence technologies significantly transforms the process of creating media-texts. The modern journalist must consider the mechanisms behind recommendation algorithms not only when choosing their subject but also when choosing means of expression within the text. This creates many problems - both creative and technical-technological ones. In this article, we attempt to analyse the recommendation algorithms of social networks (Vkontakte, Dzen, Twitter), video-hosting sites (YouTube, Tiktok) and major search engines, determine their influence on the creative process, outreach, and consumption of media-texts. Relying on the method of content-analysis as well as the historical-functional method, we highlight key issues that result from recommendation algorithms and suggest possible solutions.
First anniversaries of the breakthrough of the blockade of Leningrad on the pages of “Leningradskaya Pravda” (1944–1947)
Authors: Glezerov S. E.
Published: May 2024

The article analyzes the reflection of the breakthrough of the blockade of Leningrad in the main city newspaper. Since 1945, this event has been in the shadow of the complete liberation of the city from the blockade. While in January 1943 many Leningraders perceived this event as a milestone and key. In January 18, 1945 the anniversary of the breakthrough of the blockade was not mentioned on the pages of “Leningradskaya Pravda”. In 1946 and 1947, the third and fourth anniversaries were marked rather modestly. The main attention invariably shifted towards January 27 – the day of the complete liberation of Leningrad from the blockade. In fact, both dates – January 18 and January 27 – have gained equal importance only since the beginning of the 2000s.
Complexes with rosette glass beads (Alekseeva-480-482,490,492 / T-M-362) in Central Europe and their dating potential
Authors: Krasnopeorov A. A.
Published: May 2024

The article examines complexes with finds of glass beads with rosette ornament (Alekseeva-480-482,490,492 / T-M-362) in Central Europe. Thanks to these parallels, a chronology is established that makes it possible to clarify the dating of their existence in Eastern Europe, and the potential for using them as independent chronological indexes. The considered complexes contain a fairly constant, repetitive set of inventory: fibulas A-162, 167, 168, 211, bucket-shaped pendants, buckles ML-D-17/29, beads T-M-198/213, 266/267, 294/297, 322, 360-361, amber eight-shaped pendants. The finds clearly distinguish two groups with a slightly different chronology: on the Baltic area, the graves can be dated a little earlier – B2-C1a-C1b, on the territory of Poland – C1b-C2a-C2b, with a single case of delay to C3/D. The main cultural circle of existence is the Wielbark archaeological culture, from which the Masłomęcz-Grupp stands out, demonstrating pronounced southern ties with the Chernyakhov archaeological culture and the Sarmatians of the Limes. It is curious that in the Chernyakhov culture itself, finds of beads with rosette ornament are rare, and among the Sarmatians (and related groups): they are numerous on the Limes, but the further east (Crimea, Don-Volga steppes), they are less frequent. In Sarmatian monuments, beads are found with equipment that fit into the dates of the 2nd half. II – 1st half. III cent. AD.

Semantic-Pragmatic Potential of Advertising Texts
Authors: Hao Ding
Published: May 2024

The article deals with issues related to the features of the functioning and
identification of the semantic and pragmatic potential of advertising texts on the
example of outdoor advertising. The material of the study was advertising banners
selected by continuous sampling from various Internet portals, the content of which is
determined by the presence of non-verbal text elements and verbal signs interacting with
each other. Outdoor advertising is considered from the point of view of pragmatic
potential, the nature of which depends on the choice of language units with a certain
denotative and connotative meaning that affects communication strategies. It is shown
that when creating an advertising text, the author can use various techniques and
methods of influencing the addressee so that the advertising message attracts attention
and produces the proper communicative effect (incitement to action). The article
considers the advertising text as a semiotically complicated phenomenon, consisting of a
set of lexico-semantic means and their relationship with visual elements.
CHARACTERS-PLAYERS IN THE GAMBLER BY F. M. DOSTOEVSKY AND WOLF AMONG WOLVES BY H.
FALLADA: COMPARATIVE ANALYSIS
Authors: Melnikova L.A.
Published: May 2024

The article is devoted to comprehending the features of the representation of the
characters-players in the novels ‘The Gambler’ by F. M. Dostoevsky and ‘Wolf among
Wolves’ by H. Fallada. Using a comparative historical method of research, parallels are
identified in the development of the storylines of the works, related to the theme of
the game, as well as similar means of revealing the main characters. It is found that
both the authors set themselves the task of reconstructing the psychological portrait of
the character-player revealing the influence of the game on the human mind, his way of
thinking and behaviour. The leading means of revealing the characters of Alexei
Ivanovich in The Gambler and Wolfgang Pagel in Wolf Among Wolves are speech
characteristic, internal monologue, expressive artistic detail, portrait-assessment.
However, if in the novel by F. M. Dostoevsky the theme of the game is central, in the
novel by H. Fallada the psychological collisions of the character-player are covered
only in the first part of the work. Both the authors consistently trace the dynamics of
changes in the attitude of their characters to the game, showing how prudence gives way
to impulsive and thoughtless actions, which ultimately leads the characters to a state
of moral and material collapse. However, if H. Fallada in the finale of his work shows
his character freed from a pernicious vice and able to morally transform, F. M.
Dostoevsky’s finale of The Gambler depicts a morally degraded character, completely
absorbed in the elements of the game, but at the same time retaining hope for his
spiritual resurrection.
SOCIALIST COMPETITION AND SHOCK WORK AT FOOD INDUSTRY ENTERPRISES IN LENINGRAD IN
1929–1935
Authors: Kolobova A. V.
Published: May 2024

The article examines the course of socialist competition and shock work at the
food industry enterprises in Leningrad in 1929–1935. The creation of shock brigades by
the management of factories and plants is analyzed. To make shock work a mass movement,
the factory administration inadvertently created a group of fake shock workers. Other
reasons for the appearance of fake shock workers in production are indicated. Particular
attention is paid to the activities of shock brigades; their inability to demonstrate
high performance under adverse working conditions is emphasized. It tells about the
ideological content of socialist competition and shock work, in which the official
authorities saw a way to build socialism in the USSR. It is noted that the workers did
not realize the social significance of economic and political campaigns. In order to
encourage the production workers to participate more actively in the movement, an
attempt was made to interest them financially, but it was not successful. It is
concluded that socialist competition and shock work could not solve the tasks set by the
country's leadership.
ESTABLISHING LEGAL BASE FOR UNDERGROUND MOVEMENT OF LENINGRAD REGION IN SECOND HALF
OF 1941
Authors: Vorob'ev D. A.
Published: May 2024

Currently, the source study part of the underground movement of the Leningrad
region is poorly investigated. The problem is that over the past 82 years there have
been no works where the authors would have conducted a detailed analysis of them. This
applies not only to diaries and memoirs, but also to legislative acts. In the presented
article, the author analyzes in detail those of them that were published by the
governing bodies of the USSR, Leningrad, and Leningrad region in June – December 1941.
Based on them, the process of their creation, adoption and further implementation was
described. They were created taking into account the military situation that existed
during the period concerned. This process was also influenced by the fact that many
Leningrad party workers did not take part in the Civil War and had no experience in
creating underground organizations. Despite this, they laid the foundation for the
formation of an underground movement.

"lonely person" on the basis of the results of a free associative chain
experiment on the stimuli "lonely", data from Russian dictionaries and
illustrative material from the National Corpus of the Russian Language. In the structure
of the frame, nine slots and their terminals are allocated, related to three spheres of
a lonely person's life: the physiological sphere, the internal sphere of a person, and
the sphere external to the subject. As a result of the study, a schematized model of the
frame is presented.

Teorias das formas de transição de regimes na África pós-colonial
Authors: Domingos António Nelson
Published: May 2024

Neste artigo, pretende-se analisar as teorias das formas de transição de regimes políticos considerados como não democráticos para regimes políticos categorizados como democráticos. As teorias das formas de transição, a saber: depois da derrocada ou colapso do regime; da transformação ou reforma; do afastamento voluntário; e da transação, resultaram de estudos desenvolvidos mormente a partir dos anos de 1980 sobre o desvanecimento de regimes políticos considerados como não democráticos, na chamada terceira onda de democratização iniciada na década de 1970. Com base nestas teorias, procura-se perscrutar sobre as formas de transição de regimes em alguns Estados africanos no período pós-colonial e identificar a influência dos factores externos na determinação da forma transicional.
Anocracia en su laberinto
Authors: Puello-Socarrás José Francisco , Gunturiz Angélica
Published: May 2024

Este trabajo desarrolla, primero, la categoría de anocracia como una forma de superar distintos obstáculos (teóricos, epistémicos, metodológicos) dentro de las caracterizaciones que históricamente se han hecho sobre el régimen y el sistema políticos colombiano. Las alternativas nocionales hoy disponibles sugieren quedar aún entrampadas en categorías obsoletas, anacrónicas y reductoras que obligarían una revisión de fondo en su utilidad y verosimilitud de la mano de enfoques complejos. De allí, en segundo lugar, se expone una tipificación de qué es (y podría ser) la anocracia como forma de gobierno basada en una síntesis teórica-empírica-histórica sustentada en el caso paradigmático y demostrativo de Colombia (1948-2022). Un tercer apartado se propone dar cuenta de uno de los mecanismos especiales, aunque no exclusivos de la condición anocrática: los estados de excepción pre y post la (nueva) Constitución política expedida en 1991, pues esta figura legal resulta ser tanto una vía como una guía dentro de la evolución anocrática para el caso colombiano.
