СТЕПНАЯ ЗОНА УКРАИНЫ: ЖАНРОВАЯ ПАЛИТРА СЕЛЬСКОЙ МУЗЫКАЛЬНОЙ ТРАДИЦИИ В РАЙОНЕ ДНЕПРОВСКИХ ПОРОГОВ
Authors: Lyubimova Anastasia Yakovlevna
Published: April 2022

The folk song culture of southern Ukraine has only fragmentarily been studied. One of the most annoying blank spots is the traditions in areas where Ukrainian Cossack culture formed, the area of the Dnieper rapids and the adjacent territories (the lands of the modern Dnipropetrovsk region). Several expeditions were conducted there by ethnomusicologists from the 1990s to the 2020s. The article provides an overview of the main song genres obtained during these expeditions, and a general look at local song styles at the beginning of the 21st century.
Practical Application of the New Homogeneity Screening Procedure Added to ASTM E1921-20 and Appendix X5 Inhomogeneous Data Treatment
Authors: Hall J. Brian , Lucon Enrico , Server William
Published: April 2022

In 2019, the ASTM E08.07.06 subcommittee added a homogeneity screening procedure to ASTM E1921, Standard Test Method for Determination of Reference Temperature, To, for Ferritic Steels in the Transition Range. The screening procedure is intended to determine if the data set may be representative of a macroscopically inhomogeneous material. If the material fails the screening criterion, the subcommittee added Appendix X5, “Treatment of Potentially Inhomogeneous Data Sets,” to enable more accurate assessment of the material. Several existing large fracture toughness data sets of reactor pressure vessel low alloy steel plates, forgings, and welds were assembled to evaluate the homogeneity screening procedure and the Appendix X5 treatment methods. Several subsets of data from each of the large data sets were separately evaluated. The small data subsets are intended to approximate the number of specimens generally tested for an irradiated material (typically less than 20). The data set is screened and, if found inhomogeneous, treated according to the procedure in Appendix X5 that applies to small subsets of data. The results from the various subsets are compared with the parent large data set to assess the ability of the least conservative data subsets to bound the full data set. It is shown that, depending on the screening outcome, different margin adjustments than those recommended in ASTM E1921-20 can be used to provide results that bound a high percentage of the data. In addition, the experience presented in interpreting and using the procedures for the various data subsets has provided valuable insight for future applications.
The Retinal Basis of Light Aversion in Neonatal Mice

Published: April 2022

Aversive responses to bright light (photoaversion) require signaling from the eye to the brain. Melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs) encode absolute light intensity and are thought to provide the light signals for photoaversion. Consistent with this, neonatal mice exhibit photoaversion before the developmental onset of image vision, and melanopsin deletion abolishes photoaversion in neonates. It is not well understood how the population of ipRGCs, which constitutes multiple physiologically distinct types (denoted M1-M6 in mouse), encodes light stimuli to produce an aversive response. Here, we provide several lines of evidence that M1 ipRGCs that lack the Brn3b transcription factor drive photoaversion in neonatal mice. First, neonatal mice lacking TRPC6 and TRPC7 ion channels failed to turn away from bright light, while two photon Ca2+imaging of their acutely isolated retinas revealed reduced photosensitivity in M1 ipRGCs, but not other ipRGC types. Second, mice in which all ipRGC types except for Brn3b-negative M1 ipRGCs are ablated exhibited normal photoaversion. Third, pharmacological blockade or genetic knockout of gap junction channels expressed by ipRGCs, which reduces the light sensitivity of M2-M6 ipRGCs in the neonatal retina, had small effects on photoaversion only at the brightest light intensities. Finally, M1s were not strongly depolarized by spontaneous retinal waves, a robust source of activity in the developing retina that depolarizes all other ipRGC types. M1s therefore constitute a separate information channel between the neonatal retina and brain that could ensure behavioral responses to light but not spontaneous retinal waves.

SIGNIFICANCE STATEMENTAt an early stage of development, before the maturation of photoreceptor input to the retina, neonatal mice exhibit photoaversion. On exposure to bright light, they turn away and emit ultrasonic vocalizations, a cue to their parents to return them to the nest. Neonatal photoaversion is mediated by intrinsically photosensitive retinal ganglion cells (ipRGCs), a small percentage of the retinal ganglion cell population that express the photopigment melanopsin and depolarize directly in response to light. This study shows that photoaversion is mediated by a subset of ipRGCs, called M1-ipRGCs. Moreover, M1-ipRGCs have reduced responses to retinal waves, providing a mechanism by which the mouse distinguishes light stimulation from developmental patterns of spontaneous activity.
Isolating the Neural Substrates of Visually Guided Attention Orienting in Humans
Authors: McDonald John J. , Tay Daniel , Prime David J. , Hillyard Steven A.
Published: April 2022

The neural processes that enable healthy humans to orient attention to sudden visual events are poorly understood because they are tightly intertwined with purely sensory processes. Here we isolated visually guided orienting activity from sensory activity using event-related potentials (ERPs). By recording ERPs to a lateral stimulus and comparing waveforms obtained under conditions of attention and inattention, we identified an early positive deflection over the ipsilateral visual cortex that was associated with the covert orienting of visual attention to the stimulus. Across five experiments with male and female adult participants, this ipsilateral visual orienting activity (VOA) could be distinguished from purely sensory-evoked activity and from other top-down spatial attention effects. The VOA was linked with behavioral measures of orienting, being significantly larger when the stimulus was detected rapidly than when it was detected more slowly, and its presence was independent of saccadic eye movements toward the targets. The VOA appears to be a specific neural index of the visually guided orienting of attention to a stimulus that appears abruptly in an otherwise uncluttered visual field.

SIGNIFICANCE STATEMENTThe study of visual attention orienting has been an important impetus for the field of cognitive neuroscience. Seminal reaction-time studies demonstrated that a suddenly appearing visual stimulus attracts attention involuntarily, but the neural processes associated with visually guided attention orienting have been difficult to isolate because they are intertwined with sensory processes that trigger the orienting. Here, we disentangled orienting activity from sensory activity using scalp recordings of event-related electrical activity in the human brain. A specific neural index of visually guided attention orienting was identified. Surprisingly, whereas peripheral sensory stimulation is processed initially and predominantly by the contralateral visual cortex, this electrophysiological index of visual orienting was recorded over the cerebral hemisphere that was ipsilateral to the attention-capturing stimulus.

During aging, microglia produce inflammatory factors, show reduced tissue surveillance, altered interactions with synapses, and prolonged responses to CNS insults, positioning these cells to have profound impact on the function of nearby neurons. We and others recently showed that microglial attributes differ significantly across brain regions in young adult mice. However, the degree to which microglial properties vary during aging is largely unexplored. Here, we analyze and manipulate microglial aging within the basal ganglia, brain circuits that exhibit prominent regional microglial heterogeneity and where neurons are vulnerable to functional decline and neurodegenerative disease. In male and female mice, we demonstrate that VTA and SNc microglia exhibit unique and premature responses to aging, compared with cortex and NAc microglia. This is associated with localized VTA/SNc neuroinflammation that may compromise synaptic function as early as middle age. Surprisingly, systemic inflammation, local neuron death, and astrocyte aging do not appear to underlie these early aging responses of VTA and SNc microglia. Instead, we found that microglial lysosome status was tightly linked to early aging of VTA microglia. Microglial ablation/repopulation normalized VTA microglial lysosome swelling and suppressed increases in VTA microglial density during aging. In contrast, CX3CR1 receptor KO exacerbated VTA microglial lysosome rearrangements and VTA microglial proliferation during aging. Our findings reveal a previously unappreciated regional variation in onset and magnitude of microglial proliferation and inflammatory factor production during aging and highlight critical links between microglial lysosome status and local microglial responses to aging.

SIGNIFICANCE STATEMENTMicroglia are CNS cells that are equipped to regulate neuronal health and function throughout the lifespan. We reveal that microglia in select brain regions begin to proliferate and produce inflammatory factors in late middle age, months before microglia in other brain regions. These findings demonstrate that CNS neuroinflammation during aging is not uniform. Moreover, they raise the possibility that local microglial responses to aging play a critical role in determining which populations of neurons are most vulnerable to functional decline and neurodegenerative disease.
Spatial Learning Drives Rapid Goal Representation in Hippocampal Ripples without Place Field Accumulation or Goal-Oriented Theta Sequences
Authors: Pfeiffer Brad E.
Published: April 2022

The hippocampus is critical for rapid acquisition of many forms of memory, although the circuit-level mechanisms through which the hippocampus rapidly consolidates novel information are unknown. Here, the activity of large ensembles of hippocampal neurons in adult male Long-Evans rats was monitored across a period of rapid spatial learning to assess how the network changes during the initial phases of memory formation and retrieval. In contrast to several reports, the hippocampal network did not display enhanced representation of the goal location via accumulation of place fields or elevated firing rates at the goal. Rather, population activity rates increased globally as a function of experience. These alterations in activity were mirrored in the power of the theta oscillation and in the quality of theta sequences, without preferential encoding of paths to the learned goal location. In contrast, during brief “offline” pauses in movement, representation of a novel goal location emerged rapidly in ripples, preceding other changes in network activity. These data demonstrate that the hippocampal network can facilitate active navigation without enhanced goal representation during periods of active movement, and further indicate that goal representation in hippocampal ripples before movement onset supports subsequent navigation, possibly through activation of downstream cortical networks.

SIGNIFICANCE STATEMENTUnderstanding the mechanisms through which the networks of the brain rapidly assimilate information and use previously learned knowledge are fundamental areas of focus in neuroscience. In particular, the hippocampal circuit is a critical region for rapid formation and use of spatial memory. In this study, several circuit-level features of hippocampal function were quantified while rats performed a spatial navigation task requiring rapid memory formation and use. During periods of active navigation, a general increase in overall network activity is observed during memory acquisition, which plateaus during memory retrieval periods, without specific enhanced representation of the goal location. During pauses in navigation, rapid representation of the distant goal well emerges before either behavioral improvement or changes in online activity.

Retinal ganglion cells (RGCs) die after optic nerve trauma or in degenerative disease. However, acute changes in protein expression that may regulate RGC response to injury are not fully understood, and detailed methods to quantify new protein synthesis have not been tested. Here, we develop and apply a newin vivoquantitative measure of newly synthesized proteins to examine changes occurring in the retina after optic nerve injury. Azidohomoalanine, a noncanonical amino acid, was injected intravitreally into the eyes of rodents of either sex with or without optic nerve injury. Isotope variants of biotin-alkyne were used for quantitative BONCAT (QBONCAT) mass spectrometry, allowing identification of protein synthesis and transport rate changes in more than 1000 proteins at 1 or 5 d after optic nerve injury.In vitroscreening showed several newly synthesized proteins regulate axon outgrowth in primary neuronsin vitro. This novel approach to targeted quantification of newly synthesized proteins after injury uncovers a dynamic translational response within broader proteostasis regulation and enhances our understanding of the cellular response to injury.

SIGNIFICANCE STATEMENTOptic nerve injury results in death and degeneration of retinal ganglion cells and their axons. The specific cellular response to injury, including changes in new protein synthesis, is obscured by existing proteins and protein degradation. In this study, we introduce QBONCAT to isolate and quantify acute protein synthesis and subsequent transport between cellular compartments. We identify novel candidate protein effectors of the regenerative response and uncover their regulation of axon growthin vitro, validating the utility of QBONCAT for the discovery of novel regulatory and therapeutic candidates after optic nerve injury.
Textual Jealousies in Chariton’s Callirhoe
Authors: Elmer David F.
Published: April 2022

Chariton’s novel, Chaereas and Callirhoe, is intensely interested not only in the emotional experience of the protagonists but also in the emotional effect the narrative has on readers. Among the many emotions depicted within the text, one stands out for its architectonic function: jealousy. Jealousy articulates the plot and propels it forward. Jealousy is also represented as a fundamentally “readerly” emotion: scenes of reading focus on the potential of written texts (letters) to stir jealous emotions. Similarly, scenes of embedded narration focus on the jealous reactions of narratees. The plot achieves closure when Chaereas learns to manage his jealousy as narratee and narrator. His experience, however, has implications also for Chariton and his readers. The text’s representation of jealousy as a narrative and textual force speaks both to the experience of writing in a culture that prizes the imitation of prestigious models and to the experience of reading a text that self-consciously hybridizes those models.

El presente artículo es una aproximación al estudio del cartel cubano como herramienta ideológica dentro de la Guerra Fría cultural, cuando la imagen revolucionaria evoluciona con las diversas etapas del movimiento revolucionario cubano. Desde la década del cincuenta hasta el denominado periodo especial, en los carteles cubanos, se encuentran temáticas recurrentes como la defensa de la autonomía nacional y los conflictos armados periféricos entre los bloques socialista y capitalista. A manera de introducción al tema principal se analiza la obra de exponentes connotados del movimiento gráfico político y la función propagandística de OSPAAAL como difusor y soporte ideológico a otros movimientos revolucionarios en la Centroamérica de los años ochenta.
Reflexiones sobre la historia, legitimación e inserción del tatuaje en el arte contemporáneo
Authors: Brenes Tatiana Muñoz
Published: April 2022

Más que un recorrido cronológico por la historia del tatuaje, nos proponemos descubrir cómo algunos hitos de esta historia, aún en construcción, todavía no muy clara del todo, está llena de contradicciones, de uso del poder, de estatus sociales, políticos y religiosos; pero siempre con un elemento de segregación, exclusión y distinción de individuos y grupos, sea a través de marcas voluntarias y consensuadas, o no. En ocasiones, como veremos, se ha vivido esta práctica según una doble moral o un doble discurso que nos permite problematizar –contrario a lo que el estigma social sostiene– que los tatuajes no son solo un signo de desviación. Posteriormente, terminaremos con una discusión acerca de la inserción del tatuaje dentro del paisaje del arte contemporáneo, a partir de categorías extrapoladas desde el concepto histórico y “oficial” del Arte.
FIRE GAS PLUMES DURING THE 1927 YALTA EARTHQUAKES
Authors: Shnyukov Ye.F. , Kobolev V.P.
Published: April 2022

In the Black Sea near Yalta in 1927 there were massive methane outbursts, accompanied by flames over the water. The fire was associated with methane emissions that entered through tectonic faults. The faults were caused by seismic movements. The article analyses the depth structure of the focal zones and the nature of the seismic process and assesses the nature of the manifestations of the fires. The main factor is thought to be methane, which rises from the earth’s crust during earthquakes. The electric spark discharges generated by friction and collision of the earth’s crust ignited methane gas. The massive gas emissions of millions of cubic meters that can be called gas plumes have been fixed. The spatial and temporal direction of the fire phenomena has been established. The main fire outbreaks over the water extended in two directions. The first, the Sevastopol­Evpatoria zone, stretches submeridionally to the coast and follows the Mykolayiv fault system. The second one is the Yalta­ Alushta zone with north-eastern extension. It is associated with tectonic faults within the Circum­Black Sea region, fault zone. This fault zone is active even at present, as indicated by seismicity, the structure of the consolidated crust and sedimentary strata, bottom topography forms, etc. Analysis of geological and geophysical materials, and seismicity of the northern Black Sea region, indicate that the fire events during the Yalta earthquakes in 1927 were caused by massive methane ejections as a result of a powerful mantle gas-fluid flow into the dissolved zones of the crystalline basement along the tectonic faults of different scales within the Odessa­Sinop and Circum Black Sea fault zones. Earthquakes triggered the activation of tectonic faults in benthic sedimentary horizons for the migration of focused deep-seated gas-fluid streams.

Published: April 2022

The resin compound is obtained from Jernang (Daemonorops draco blume), a plant that grows in the tropical rainforests of Indonesia. This study was undertaken to determine the antibacterial ability of ethanol extract of Jernang resin against both Salmonella typhi and Streptococcus mutans. The crude extract was prepared by soxhlet extraction in ethanol, is then fractionated vacuum liquid chromatography (VLC) with increasing solvent polarity starting from n-hexane (100%); n-hexane: ethyl acetate (80:20); ethyl acetate: methanol (40:60) up to methanol (100%) by. The antibacterial activity were evaluated using the disc diffusion method, these were compared with that of standards chloramphenicol as positive control and DMSO as a negative control. Determination of the antibacterial activity, we verified the diameter of inhibition of growth zone against Salmonella typhi at the variation of the extract concentration were 0.00mm/10ppm, 9.03mm/50ppm, 8.4mm/100ppm, 11.73mm/500ppm. These were compared with that of standards chloramphenicol (21.03mm/300ppm) and DMSO (0.00mm/300ppm). On the other hands, the diameter of inhibition of growth zone against Streptococcus mutans at the variation of the extract concentration were 9.33mm/50ppm, 9.83mm/75ppm, 10.67mm/100ppm, 11.5mm/125ppm, and 13.33mm/150ppm. These were compared with that of standards chloramphenicol (25.7mm/300ppm) and DMSO (0.00mm/300ppm). The ethanol extract of Jernang Resin exhibited antibacterial effects on Salmonella typhi and Streptococcus mutans, but these effects were less than chloramphenicol. The antibacterial effect increased with an increase in the concentration of the extract.

OBJECTIVES

The objective of this study was to develop and validate an approach to accurately identify incident pediatric neuropsychiatric events (NPEs) requiring hospitalization by using administrative data.

METHODS

We performed a cross-sectional, multicenter study of children 5 to 18 years of age hospitalized at two US children’s hospitals with an NPE. We developed and evaluated 3 NPE identification algorithms: (1) primary or secondary NPE International Classification of Diseases, 10th Revision diagnosis alone, (2) NPE diagnosis, the NPE was present on admission, and the primary diagnosis was not malignancy- or surgery-related, and (3) identical to algorithm 2 but without requiring the NPE be present on admission. The positive predictive value (PPV) of each algorithm was calculated overall and by diagnosis field (primary or secondary), clinical significance, and NPE subtype.

RESULTS

There were 1098 NPE hospitalizations included in the study. A total of 857 confirmed NPEs were identified for algorithm 1, yielding a PPV of 0.78 (95% confidence interval [CI] 0.76–0.80). Algorithm 2 (n = 846) had an overall PPV of 0.89 (95% CI 0.87–0.91). For algorithm 3 (n = 938), the overall PPV was 0.86 (95% CI 0.83–0.88). PPVs varied by diagnosis order, NPE clinical significance, and subtype. The PPV for critical clinical significance was 0.99 (0.97–0.99) for all 3 algorithms.

CONCLUSIONS

We identified a highly accurate method to identify neuropsychiatric adverse events in children and adolescents. The use of these approaches will improve the rigor of future studies of NPE, including the necessary evaluations of medication adverse events, infections, and chronic conditions.
Rethinking Development: Vikalp Sangam and the search for alternatives in India
Authors: Das Pallav
Published: April 2022

It is increasingly becoming evident that the current model of “development” has led the world to the brink of a climate disaster, as the very fundamentals of the natural systems on which the world’s current economic structure is predicated upon stand compromised. Vast tracts of lands have become poisoned and barren, and the rising seas are threatening coastal cities and ecosystems. As people begin to make sense of this rapidly devolving situation, some serious and well-considered attempts are being made to craft an alternative model of human existence. In India, Vikalp Sangam or the “Confluence of Alternatives” is an emerging platform, which is leading this exploration through a blend of modern progressive thinking, and ancient wisdom of indigenous peoples and other traditional community worldviews. It is empowering these ideas as well as the practice of alternatives to reach a large audience and become viable for discussion, analysis and eventual replication in other places. This paper analyzes the opinions, facts, theories and data emerging out of the Vikalp Sangam process to understand the evolution of “alternatives” thinking in India, and how it can influence the process of recalibrating the larger idea of development in the country. It focuses on the process by which a fundamental and transformative systemic change could be introduced into the society for the construction of a new political-economy that moves beyond both corporate capitalism and state socialism and towards the creation of “Radical Ecological Democracy”, based on climate justice, environmental sustainability and socio-economic equality.

Desde mis vivencias y sentipensar presento una mirada sobre la situación de la minería del oro en el norte del Cauca (Colombia), una región histórico-cultural interétnica e intercultural con una fuerte y mayoritaria presencia de afrodescendientes. Esta mirada tendrá énfasis en las experiencias de dos consejos comunitarios (organización de las comunidades negras, reconocidos por la ley 70 de 1993 y función de administración de tierras en propiedad colectiva) del norte del Cauca, Colombia, y en la acción colectiva de La movilización de mujeres afrodescendientes por el cuidado de la vida y los territorios ancestrales, por lo que serán retazos de historias antiguas y nuevas que aportan a narrativas que se tejen en tiempos pasados y presentes, en escenarios cotidianos-locales, como también, en otros más amplios. Con ellas hablaremos de los procesos de re-existencia de las comunidades negras para pervivir en sus territorios: los consejos comunitarios de La Toma –en el municipio de Suárez– y Cuenca del rio Cauca y microcuencas de los ríos Teta y Mazamorrero –en los municipios de Buenos Aires y Santander de Quilichao; cuyas historias expresan el poder colectivo del pueblo negro.
Transformaciones del rol del Estado colombiano en relación con la producción de hidroenergía
Authors: Vanegas-Galindo Alix Stella , Rojas-Robles Rosario
Published: April 2022

Mediante el uso de técnicas de revisión documental, esta investigación identificó los cambios del rol del Estado en la producción de hidroenergía. En la primera parte se caracteriza el rol del Estado de tipo fomentista (1936-1994) y se contrasta con el rol regulador del Estado (1994 en adelante). Se identifican los conflictos históricos en relación con la energía eléctrica y debido a ellos, se reseñan los esquemas institucionales con los cuales el Estado intentó resolverlos. Se llega a la conclusión que bajo el rol regulador el Estado colombiano se ha generado una institucionalidad que favorece la producción de hidroenergía con rendimientos empresariales importantes, gestionando el territorio con criterios de productividad. Sin embargo, la conflictividad por los impactos derivados de la construcción de hidroeléctricas viene en aumento en el país sin que se avizore una institucionalidad a través de la cual el Estado busque solucionar estos conflictos a bajos costos sociales y ambientales.

Después de siglos de tejer la cultura anfibia en el río Sinú y vivir intensas luchas por la permanencia territorial, la Asociación de Pescadores, Campesinos, Indígenas y Afrodescendientes para el Desarrollo Comunitario de la Ciénaga Grande del bajo Sinú (ASPROCIG) viene planteando una propuesta de desarrollo territorial, como una metodología llamada Z, para lograr que las comunidades vivan sabroso y en armonía con el territorio. Esta propuesta surge antes de la profunda ruptura generada por el proyecto hidroeléctrico Urrá, con el que se intensificaron otras trayectorias territoriales conflictivas y se motivó el desplazamiento y el retroceso de las condiciones de vida de muchas comunidades. La metodología Z, después de más de 25 años, se propone como un modelo que puede motivar también la permanencia territorial y la transición socioecológica en otros territorios.

Represando el alto Magdalena: conflicto ambiental por la construcción y operación de la central hidroeléctrica El Quimbo
Authors: Clavijo-Bernal Omar F.
Published: April 2022

La construcción de El Quimbo en el departamento del Huila, Colombia, guarda correspondencia con la vocación hidroenergética conferida a la cuenca alta del río Magdalena, en donde existen antecedentes al respecto (central Betania) y en donde se proponen proyectos similares en instrumentos como el Plan Maestro para el Aprovechamiento del río Magdalena. Sin embargo, el aprovechamiento visto de este modo pasa por alto las particularidades ecológicas, socioeconómicas y culturales de los territorios en que tiene lugar, propiciando el surgimiento de problemáticas relacionadas con la transformación de los ecosistemas de soporte, así como de conflictos ambientales dada la dependencia de las comunidades y del aparato productivo en relación con las dinámicas ecológicas allí presentes. En tal dirección, este artículo de revisión recoge la experiencia de El Quimbo para señalar algunas de las implicaciones de los proyectos hidroenergéticos sobre las dinámicas territoriales a nivel local, realizando una cronología de los principales hechos que atravesaron la movilización social y la interposición de recursos legales para el caso analizado, sobre lo cual se llama la atención frente a la eventual construcción de nuevas centrales en el alto Magdalena.

Published: April 2022

Este artículo presenta los resultados de evaluación de la calidad de los procesos en las empresas de reciclaje de la localidad de Rafael Uribe Uribe, en Bogotá. Se establecen los elementos teóricos manejados relacionados con la calidad de los procesos en estas empresas, para luego analizar la relación de las variables independientes de productividad, competitividad e innovación con la variable dependiente de calidad, considerando estudios e investigaciones al respecto. De esta manera, entendiendo las variables consideradas, es posible definir conceptos. Con esta información se crea y valida un instrumento mediante el cual se analizan estadísticamente los datos recopilados en campo, y se establecen las correlaciones de todas las variables con sus respectivas dimensiones. Al mismo tiempo, se realiza un análisis factorial para identificar la interdependencia de las variables y determinar la explicación de cada una. Los resultados revelaron baja calidad en los procesos de las empresas de reciclaje: se manejan muy informalmente, y el aprovechamiento de los recursos resulta inapropiado; en consecuencia, es necesario establecer un mejoramiento de procesos, con el fin de organizar las empresas de reciclaje en Bogotá.
Ecoturismo como alternativa de desarrollo económico, ambiental y cultural: un reto en calidad, formación y consolidación de la economía naranja
Authors: Rico-Ramírez Mónica Sofía , Gómez-Caipa Juan Camilo
Published: April 2022

Colombia, particularmente, tiene una condición privilegiada, biodiversa y ambientalmente sostenible; sobresale en patrimonio inmaterial, material y ecológico, que la sitúan en uno de los ecosistemas más ricos en flora, fauna y cultura. Dentro de la economía se presenta la necesidad de incorporar la gestión cultural, los métodos administrativos y la calidad en el servicio para consolidar una categoría que lleve al desarrollo de productos en torno a la cultura. Lo anterior se denomina Economía naranja, y remite a un modelo de desarrollo ampliamente conocido. Así, cuando se habla de ecoturismo no solo se mencionan actividades recreativas, se incorpora también la cadena productiva, la integración social de grupos y culturas étnicas, campesinos, afrodescendientes y población migrante, viajeros, turistas y visitantes. Plantea la inclusión de los ecosistemas protegidos (reservas y parques naturales, sitios arqueológicos, monumentos naturales, etc.), la creación de valor empresarial, social y económico con responsabilidad y respeto por la preservación y el mejoramiento constante de los sistemas productivos, que permitan hacer del servicio prestado un ecoturismo como alternativa de desarrollo económico, ambiental y cultural.
Assessment of Criteria for Specific Internet-use Disorders (ACSID-11): Introduction of a new screening instrument capturing ICD-11 criteria for gaming disorder and other potential Internet-use disorders
Authors: Müller Silke M. , Wegmann Elisa , Oelker Andreas , Stark Rudolf , Müller Astrid , Montag Christian , Wölfling Klaus , Rumpf Hans-Jürgen , Brand Matthias
Published: April 2022

Background and aims

With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may also be applied to other potential specific Internet-use disorders, which may be classified in ICD-11 as other disorders due to addictive behaviors, such as online buying-shopping disorder, online pornography-use disorder, social-networks-use disorder, and online gambling disorder. Due to the heterogeneity in existing instruments, we aimed to develop a consistent and economic measure of major types of (potential) specific Internet-use disorders based on ICD-11 criteria for gaming disorder.

Methods

The new 11-item Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) measures five behavioral addictions with the same set of items by following the principles of WHO’s ASSIST. The ACSID-11 was administered to active Internet users (N = 985) together with an adaptation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and screeners for mental health. We used Confirmatory Factor Analyses to analyze the factor structure of ACSID-11.

Results

The assumed four-factorial structure was confirmed and was superior to the unidimensional solution. This applied to gaming disorder and to the other specific Internet-use disorders. ACSID-11 scores correlated with IGDT-10 as well as with the measures of psychological distress.

Discussion and Conclusions

The ACSID-11 seems to be suitable for the consistent assessment of (potential) specific Internet-use disorders based on ICD-11 diagnostic criteria for gaming disorder. The ACSID-11 may be a useful and economic instrument for studying various behavioral addictions with the same items and improving comparability.

Jellyfish have wide distributions throughout the world’s oceans, with new species records emerging from increasingly broad areas as novel identification approaches are implemented, including citizen science. Here, the first accounts of Thysanostoma loriferum (Ehrenberg, 1837) and Netrostoma setouchianum (Kishinouye, 1902) in Hong Kong waters are reported based on photographs and videos collected by the Hong Kong Jellyfish Project. Together, these sightings obtained through a citizen science project provide evidence for a greater diversity of jellyfish in Hong Kong oceanic waters than has previously been recognized.

Introduction. Charcot Marie Tooth disease (CMT) is currently one of the most commonly diagnosed and commonly hereditary sensorimotor neuropathies. Concluding from the literature, this is the first study describing the case of a patient with CMT disease in the c.217G> C variant of the INF2 gene and focal segmental glomerulosclerosis. Aim. To present a case of a 16-year-old patient suffering from CMT disease in variant c.217G> C of the INF2 gene and focal glomerulosclerosis. Description of the case. The text describes the CMT disease in a patient who underwent the WES / WGS-NGS genetic test and found a mutation within the INF2 gene at the chromosomal position hg38 14: 104701582-G> C, cDNA level c.217 G> C , notation at the p protein level (Gly73Arg). Genotype record according to Human Genome Variation Society: NM_022489.4: c. [217G> C]; [217 =]. The publication includes data on genetics, molecular mechanisms of the disease, diagnostic methods, rehabilitation and surgical treatment. Conclusion. CMT disease is a heterogeneous group of diseases caused by mutations in various genes. The incidence of this pathology has increased significantly in the last century. Currently, there are no treatments available to combat this disease, and symptomatic treatment is the only treatment available.

Introduction. Bone age determination is a radiological method investigating the compatibility of ossification processes of bones with chronological ages. Aim. We aimed to investigate the use of CT staging of the medial clavicular epiphyseal ossification in bone age determination in Turkish adolescents and young adults. Material and methods. Chest CT exams of 2018 patients between 11 and 35 years of age were retrospectively evaluated for epiphyseal ossification stages of the bilateral medial clavicles (4036 clavicles) on both axial&coronal images and compared with the sex and chronologic age of the individuals in Turkey. Results. For stage 2,3 and 4 the ages of women were greater than men and it was statistically significant. For an individual classified as stage 4,it can be said with certainty that he or she has already reached the age of 18.There was no statistically significant difference between left&right sides and between the axial&coronal images.In addition, it was found that the medial clavicular head epiphyses showed a lot of variation. Conclusion. CT evaluation of the medial clavicular epiphysis ossification stages is helpful in determination of the individuals over the age of 18. Regardless of the sex, the stage 4 can be used as a criterion to make the prediction that an individual is older than 18 years.

Introduction. Gastroesophageal reflux disease (GERD) is a common disease with the highest prevalence in North America. Up to 40% of patients report persistent gastroesophageal reflux disease (GERD) symptoms despite proton pump inhibitor (PPI) therapy. Aim. The aim of this article is to complete discuss the GERD characterized by heartburn and/or regurgitation symptoms. Material and methods. We discuss here the evidence for medical therapy for PPI nonresponsive GERD. Analysis of the literature. GERD may present with a variety of other symptoms, including water brash, chest pain or discomfort, dysphagia, belching, epigastric pain, nausea, and bloating. In addition, patients may experience extraesophageal symptoms like cough, hoarseness, throat clearing, throat pain or burning, wheezing, and sleep disturbances. Conclusion. There has been an increase in GERD prevalence. GERD is one of the most common gastrointestinal disorders managed by gastroenterologists and primary care physicians.
