Reserves of Alternative Ways to Resolve a Criminal Law Conflict
Authors:   Ural Branch, Russian State University of Justice, Chelyabinsk, Russia, Denis A. Gаrbatovich
Published: July 2023

The article raises the question of the problems of protecting the balance of freedom of the individual and the state by alternative means of resolving the criminal law conflict. The purpose of the work is to assess the reserve (potential) of alternative ways to resolve a criminal law conflict while protecting the balance of individual and state freedom. Research objectives: 1) identify criteria (indicators) indicating the achievement or non-achievement of the balance of individual and state freedom; 2) demonstrate the possibilities of alternative ways to resolve a criminal law conflict to protect the balance of individual and state freedom 3) assess the presence or absence of reserves in the use of alternative ways to resolve a criminal law conflict. The paper draws the following conclusions. Over-criminalization as a vector of modern Russian criminal policy violates the balance of interests of the individual and the state, which is not restored by the available alternative ways of resolving the criminal law conflict. At the level of law enforcement, the reason for this is the minimal use of the mechanism for recognizing an act as insignificant. The institution of exemption from criminal liability as one of the forms of its implementation is able to independently resolve social contradictions that have arisen as a result of violation of the criminal prohibition. Performing the restorative function of criminal law, the analyzed forms of differentiation of responsibility, applied when criminal punishment is inappropriate, provide a balance of protection of the interests of the individual and the state. This method of resolving a criminal law conflict has a reserve, it can potentially be applied to a much larger number of persons than it is used now. It is proposed to supplement some articles of the Special Part of the Criminal Code with notes with special grounds for exemption from criminal liability. When resolving a criminal law conflict, the State focuses on the use of the most repressive means of criminal law. The conviction of a person as a typical reaction of the state to the commission of a crime by him is not always considered appropriate, accordingly, the balance of individual and state freedom is not achieved and protected.

Published: July 2023

OBJECTIVES
The way of practising and teaching dentistry has changed significantly worldwide due to the COVID-19 pandemic, and the impact on dental education should not be neglected. Therefore, sharing experiences about online teaching from in-person education is essential to a better learning process during this period. This study aimed to assess the challenges faced by dental students in studying oral pathology online during covid-19: a cross-sectional study.
METHODOLOGY
It was a descriptive cross-sectional study in the Department of oral pathology at Altamash Institute of dental medicine to assess the challenges students faced during the COVID-19 pandemic. A total of 110 participants were approached, and among them, 105 participants responded. Of 105 participants, 78% were females, and 22% were males. Data were analyzed using SPSS version 23.RESULTSAlmost 93.3% of the students felt in-person lectures are more effective than online lectures. Fourth-year students showed higher satisfaction with the number of online tutorial / practical classes taken to provide an in-depth view of the subject than 3rd year students (8.8% vs 91.2%, p=0.045). Fourth-year students showed significantly higher satisfaction with several online theory classes to provide an in-depth view of the subject than 3rd year students (p=0.045).
CONCLUSION
The present study concluded that most students prefer in person classes over virtual learning and face a lack of online interaction with the faculty.

OBJECTIVES
o evaluate the biofilm activity of Escherichia coli and the anti-biofilm forming activity of Pomegranate peels Punica granatum L. and Mango leafs Mangifera Indica L. extracts against Escherichia coli and their combined synergistic effect using 96 well microtiter plate.
METHODOLOGY
The study design was a cross-sectional study. The sample size was 150. The samples were collected from patients at PNS Shifa Hospital Karachi. The age group of the individuals included was from 15 to 50 years. The specimens received in the lab were inoculated on CLED agar, Blood agar, and MacConkey’s agar culture plates. Escherichia coli was identified by colony morphology, gram staining, TSI, and further biochemical test analysis. After identification, the samples were processed for biofilm activity on 96 well microtiter plate method and using serial dilution method to assess the anti-biofilm activity of natural product extracts. Patient's age, gender, and hospital number of patients were recorded on specially designed proforma with ERC approval no 83/2021. 
RESULTSAmong 150 patients, 64% were males, and 36% were females. Overall mean age was (33.79±9.94) and (34.02±10.59) years. 90% of samples showed biofilm formation. We found a significant relationship between culture and examination (p-value 0.000), while no significant association was found between gender (p-value 0.69), age (p-value 0.44) and biofilm formation (p-value 0.57). Anti-biofilm forming activity of pomegranate peel extract against Escherichia coli was (24.46±19.09) with mean and standard deviation. Anti-biofilm forming activity of Mango leaf extract against Escherichia coli was (14.90±9.56). Significant synergistic relation was observed in both extracts, Punica granatum L. and Mango leaf extract Mangifera Indica L. used in combination.
CONCLUSION
It was concluded that a novel combination of natural product extracts had shown higher effectiveness against the rapid emergence of biofilm-forming pathogens.

OBJECTIVES
This study aimed to evaluate the impact of pregnancy profiles, socioeconomic factors, and age on maternal at teaching hospitals in Mardan, Khyber Pakhtunkhwa.
METHODOLOGY
This descriptive-exploratory/qualitative study was conducted at the genealogical outside-patient department of the Mardan Medical Complex, with the approval of the ethics committee. A total of 1187 patients attended the complex between January 2021 and January 2022. Informed consent was obtained, and a comprehensive history and physical examination were conducted using a pre-designed proforma. Patients meeting specific criteria, such as gestational age >36 weeks, singleton pregnancies, and absence of maternal co-morbidities, were included. Exclusion criteria encompassed conditions such as antepartum haemorrhage and fetal anomalies. Data analysis was performed using SPSS-24 version, ensuring the confidentiality and anonymity of participants.
RESULTSOut % of 1187 patients, 48% had previous pregnancies (multiparous), while 52% were experiencing their first pregnancy (primiparous). Gestational age distribution showed that 45% of cases fell within the 36-38 week range, and 55% were between 39-40 weeks. Regarding booking status, 29% of patients were booked, while 71% were unbooked. Finally, the socioeconomic status analysis indicates that 61% of cases were above the poverty line, while 39% were below. These findings highlight important factors such as previous pregnancies, gestational age, booking status, and socioeconomic status that can influence maternal care and outcomes. Among the different age groups, the <20 age group had the highest percentage of spontaneous deliveries (31%), while the >30 age group had the highest percentage of cesarean sections (25%). Induced labour rates were relatively consistent across age groups. Not being in labour was more prevalent in the 25-30 and >30 age groups.
CONCLUSION
The findings highlight that important factors such as previous pregnancies, gestational age, booking status, and socioeconomic status can influence maternal care and outcomes.

OBJECTIVES
To measure the frequency of sustained virologic response in Hepatitis C positive, treatment naïve patients on Sofosbuvir and Daclatasvir.METHODOLOGY
This descriptive study was conducted in the Department of Medicine, Khyber Teaching Hospital Peshawar from 15th May 2020 to 14th November, 2020.  A sample size of 93 was calculated by using sustained virologic response in 96% patients using Sofosbuvir and Daclatasvir with the confidence level as 95% and 4% margin of error under WHO formula for sample size determination in health studies. Consecutive non probability sampling technique was used in the study.RESULTSNinety Three treatment naïve hepatitis C patients were included in the study containing 53 males (57%) and 40 females (43%) with mean age of 43 + 0.23. 84 (90%) patients were in Child A class according to Child Pugh score. Overall 89 (95.7%) patients showed sustained virologic response following 12 weeks treatment of naïve HCV patients with combination of sofosbuvir and daclastavir. 5 patients developed side effects to the drugs; 2 patients developed anemia with one patient having anemia severe enough to require blood transfusion. 4 patients did not respond to the treatment regime in terms of sustained virologic response for 12 week treatment and were continued for 24 weeks on the same regime.
CONCLUSION
This study concludes that combined sofosbuvir and daclatasvir for 12 weeks appear to have sustained virologic response in treatment naïve HCV patients. Child score has statistically significant correlation to sustained virologic response with Child A class showing SVR in all patients. Patients in Child class C did not show SVR. Thrombocytopenia has direct and negative affect on SVR.

Published: July 2023

One of the problems causing society's prosperity low level is the imbalance of population growth, economic growth, and health. BKKBN (National Family Planning Coordinating Board) has a role to measure and control the growth of Indonesia's population through the KB (The Family Planning Program). In Yogyakarta, especially in Wonokromo Village, Pleret, Bantul Regency, the implementation and socialization of KB program had some obstacles because most people thought that the program seemed to be contrary to the way of the Islamic rules. Therefore, the ulama have a crucial role in changing of community’s perspective on KB in the context of Islam. Based on the background of those problems, the researcher was interested in this topic of research to understand Ulama’s role for BKKBN and the community from communication science perspective, especially Development Communication. The qualitative descriptive method is the basic method in this research. The result of the research is that Ulama play an important role in the Interpersonal Communication process with the BKKBN, and play a major role in disseminating the family planning program to the Wonokromo Community. Ulama played a role in interpreting and communicating the Family Planning Program in accordance with the Islamic perspective, so that people can accept and implement the program.
Javanese Women's Gender Reconstruction in Bumi Manusia Film
Authors: Anggun Mayanti  , Haryono Cosmas  Gatot
Published: July 2023

The film cannot be viewed solely as a form of entertainment. However, the media plays the role of social reality construction. The film Bumi Manusia, which uniquely depicts the female gender, is full of social construction roles. The female character in the film, Nyai Ontosoroh, is described as having different characteristics and abilities than Javanese women in the nineteenth century. As a result, researchers want to examine the film to see how the reconstruction of women's gender occurs in it. The researcher used a qualitative method based on Ferdinand de Saussure's semiotic approach.

According to the research findings, this film aims to rebuild women's gender roles and positions that are equal to those of men. Women are figures with equal strength and ideas to men, particularly in leadership, which has traditionally been dominated by men. Nyai Ontosoroh, as a female gender representative, is portrayed as a new reality with strong characters: resilient, not easily defeated, knowledgeable, and capable of leadership. It is hoped that this reconstruction of Nyai Ontosoroh's figure will help to dispel the old stereotype of women as weak, capable of only makeup (macak), cooking (masak), and (giving birth) manak.
Food grade microalgae-based biopigments and their production technique versus synthetic colorants
Authors: ÜÇÜNCÜOĞLU Didar
Published: July 2023

In the food industry, synthetic color-active compounds can be added as additives to replace natural colors that are damaged during processing. This addition reduces the batch-to-batch fluctuation and increases the development of new or desired products that are appealing to consumers where natural colors are absent. Synthetic colorants cannot be produced by any bioprocess. In contrast, the Food and Drug Administration declared that algae such as Chlorella, Cryptothecodinium, Dunaliella Nannochloropsis, Nitzschia, Phaeodactylum, Schizochytrium, and Spirulina are trustable sources of food pigments as natural sources. These microalgae are photoautotrophic species and can be found on the "Generally Recognized as Safe-GRAS" list of food additives. Microalgae-derived pigments, which are also known as nutraceutical supplements, have been recently used in functional food products. Some of them are used as health and color supporters because of their excellent antioxidant properties that block oxidative reactions in lipid-rich food products. Their unique properties of being harmless to the environment were scientifically proven as well. As a result, the demand for their commercial use is increasing gradually. However, the bioprocess of algae on a huge scale is very limited due to some environmental factors and is hard to produce continuously. The scope of this review was to provide concise knowledge about biopigments extracted from microalgae and their production methods and to clarify the current implementations in the industry. Additionally, food-grade biopigments were compared with synthetic ones. The primary issues with bioprocesses used to produce colorants were highlighted, and as a result, the expected studies were discussed that would be conducted soon.

Published: July 2023

The purpose of this study is to predict the initial price of new public offering stocks on the listing date for short-term excess returns of public offering stocks due to the IPO underpricing factor. This study seeks to extract the characteristic factors related to the determinants of the public offering price and derive the factors that affect the public offering price. Specifically, for IPOs to be listed on the KOSDAQ market, the public offering price decision influencing factors are derived and artificial intelligence techniques (neural networks, decision trees) are used to build a public offering price prediction model. Research variables related to the public offering price prediction model include sales, net profit, largest shareholder’s share, capital stock, number of listed stocks, sales ratio of old stocks, lead company size, institutional subscription competition rate, general subscription competition rate, mandatory holding commitment rate, distribution Available volume, public offering amount, public offering price, public offering price discount rate, etc. As a result of the study, the main variables to be considered for the prediction of the public offering price were the general subscription competition rate and the public offering price. Variables included in the ranking of importance, such as capital stock, net income, commitment ratio of obligatory holdings, and the largest shareholder's equity ratio, were also extracted as factors to be considered.

En esta investigación se evaluó la importancia que tienen las arvenses en el sostenimiento de la diversidad de insectos que visitan las flores de café. Se seleccionaron dos parcelas con manejo integrado de arvenses (MIA) y dos con manejo excesivo (MEA). En cada parcela se recolectaron y registraron los insectos visitantes de las flores de café en 30 árboles, en intervalos de ocho minutos por árbol, en tres horarios durante un día. Los muestreos se realizaron en dos eventos de floración por año, durante dos años, para un total de 192 horas de observaciones. Por parcela se identificaron los insectos y se estimaron abundancia, riqueza y diversidad del orden q=1 y q=2. Estos valores fueron comparados mediante una prueba de diferencia mínima significativa al 5%. En las parcelas MIA se trazaron tres transectos y se recolectaron los insectos visitantes de las arvenses, con igual frecuencia y forma que en el muestreo anterior, durante los períodos sin floración del café. En las flores del café de las parcelas MIA se registraron 2.347 individuos y 163 especies, en las parcelas MEA se recolectaron 2.543 individuos y 162 especies; en las arvenses se registraron 735 individuos y 171 especies. La riqueza, abundancia y valores de diversidad del orden q=1 y q=2 fueron estadísticamente iguales entre las parcelas. Las arvenses Bidens pilosa, Commelina difusa, Emilia sonchifolia, Hyptis atrorubens y Galinsoga parviflora, fueron las más visitadas por los insectos. Los resultados muestran una alta diversidad de especies de insectos visitantes florales, tanto en el cultivo del café como en las arvenses.
Efecto de los depredadores Cathartus quadricollis y Ahasverus advena (Coleoptera: Silvanidae) sobre Hypothenemus hampei en el campo
Authors: Constantino Luis Miguel , Benavides Machado Pablo
Published: July 2023

Por su comportamiento, la broca del café es difícil de controlar debido a que su ciclo de vida transcurre dentro de los frutos de café. Una alternativa es el control biológico mediante el aumento de depredadores capaces de penetrar por los orificios de los frutos infestados en el campo. Se evaluaron los depredadores Cathartus quadricollis y Ahasverus advena en el campo. Las unidades de trabajo estuvieron conformadas por una planta de café en estado productivo, encerrada con jaula entomológica. En cada árbol se ubicaron 50 granos de café infestados con broca durante 20 días, colgados de una rama (para evaluarlo con ambas especies) o colocados sobre el suelo (para A. advena). Se tuvieron dos tratamientos y dos testigos, con 15 repeticiones. Se liberaron 150 adultos de cada especie de depredador, evaluando la población de broca y los frutos infestados en el árbol a los 50 días. El análisis de varianza al 5% mostró diferencias estadísticas entre tratamientos en el número de estados de broca vivos y los frutos infestados, para las dos especies de depredadores. La prueba de Dunett al 5% indicó que A. advena disminuyó hasta 70,1% la broca cuando se ubicó en la parte aérea del árbol y en un 76,4% cuando se colocaron en el suelo. Los adultos de C. quadricollis disminuyeron significativamente los frutos infestados en el árbol en un 50,1% cuando los granos se dispusieron en las ramas. Estos depredadores son especies potenciales dentro de una estrategia de manejo integrado de la broca del café.

Published: July 2023

El café natural (CN) se destaca por sus descriptores sensoriales diferenciales en los atributos de fragancia/aroma y sabor con respecto a los cafés lavados. Dentro de los procedimientos para su obtención, el secado constituye un factor crítico para el aseguramiento de su calidad. Con el objetivo de evaluar el efecto del secado en la calidad del CN se evaluaron cinco modalidades, consistentes en un secado inicial al sol (S), complementado con secado mecánico (M): S45%+M, S50%+M, S55%+M, S100%, M100% y el testigo, café lavado 100% secado mecánicamente (LM). El CN en los diferentes tratamientos alcanzó una humedad del 10%-12%, entre 9 y 17 días; comportamiento que se describió a partir de una función de tipo logarítmico y un R2>0,92. Para el LM, el café requirió un promedio de 4 días de secado, explicada a través de un polinomio de tercer grado R2 de 0,999. El CN se destacó por presentar un contenido adecuado de actividad del agua. Respecto a las variables físicas del grano, la merma en promedio fue del 50,7% y la almendra sana de 42,6%, con valores de almendra defectuosa entre 2,6% y 6,6%. Con relación a la calidad sensorial, el puntaje total promedio SCA (Specialty Coffee Association) para el LM fue de 82,9 y para el CN de 83,9; con descriptores destacables en fragancia/aroma de chocolate, frutal, caramelo y miel, notas de pulpa dulce y vino. Los resultados llevan a concluir que un proceso adecuado de secado permite obtener CN con destacada calidad física y sensorial.

Los partidos políticos en Colombia
Authors: Cotes Zuleta Aquilino
Published: July 2023

Los partidos políticos suelen ser expresión espontánea de las comunidades, las cuales, al sectorizar sus ideas, reflejan una imagen de sus inclinaciones, de sus esperanzas y del modelo de mandato que aspiran aplique en sus territorios. Los partidos políticos suelen ser tenidos como indicador de democracia, cuando todos cuentan con las mismas garantías y oportunidades, tal como teóricamente sucede en Colombia, al cobijo del Estado Social de Derecho. No obstante, la realidad política, desde al menos más de una década, evidencia inconformidad social y política en el país; las alegaciones hablan de persecuciones, de falta de garantías, mientras el ciudadano común se pregunta qué es lo que realmente quieren los partidos, en un país donde no existe restricción alguna a la libertad personal de los coasociados. Por el contrario, son los partidos políticos los que, en realidad, se hallan en deuda con el país; una deuda multifacética, que muestra falencias en lo disciplinario, en lo social, en lo legal y, peor aún, en lo convivencial. En este documento se aborda el comportamiento de los partidos políticos, a partir del marco constitucional y legal que brinda garantías por igual, sin que el producto sea el de una comunidad respetuosa, unida en torno a unos deseos que, aunque por caminos distintos, se pueden alcanzar, porque son comunes a todos los colombianos. El Estado ha respetado la Constitución y la Ley, pero, a cambio, los partidos políticos parecen estar en deuda con la comunidad que los acoge y les brinda la oportunidad de diversificar ideas, con distintos colores y contenidos. En este artículo se hace un análisis cualitativo a los partidos, a partir del rol que juegan, en conjunto, en la calidad de vida de los colombianos.

Published: July 2023

El objetivo general de la investigación fue analizar el índice de financiamiento de las exportaciones del camarón ecuatoriano en tiempo de crisis, durante el período 2017 - 2022. La metodología empleada se basó en un estudio cuantitativo y cualitativo, con un alcance descriptivo y diseño no experimental a fin de identificar los principales factores que afectaron su índice de financiamiento, sin intervenir en las variables. En el estudio participaron 45 empresas seleccionadas por conveniencia, debido al contacto con sus representantes; asimismo se entrevistó a tres expertos. Los resultados del estudio indicaron que el sector camaronero en Ecuador enfrentó retos para el financiamiento de su producción, como limitaciones de acceso al financiamiento (66,7%), falta de garantías (35,6%) y riesgos operativos (26,7%). El financiamiento externo fue el recurso principal utilizado por las empresas (55,6%), seguido por financiamiento interno (15,6%) y una combinación de ambos (28,9%). La pandemia de COVID-19 tuvo un impacto negativo en la industria camaronera, resultando en problemas de liquidez, reducción de costos de producción y pérdidas monetarias, afectando la solvencia y las operaciones de la industria. Se concluye que las empresas han utilizado estrategias de apalancamiento para superar los efectos de la crisis, pero se requiere apoyo externo para mantener la liquidez.

Published: July 2023

La conversión de las potencialidades turísticas en habilidades para el mejoramiento de la calidad de vida, pasa por las acciones que pudieran emprender las comunidades, las organizaciones y la propia población, fortalecidas desde lo que significa la gestión turística, oportuna y adecuada. Siendo así, el estudio que origina este artículo busca cumplir con el objetivo de describir la situación actual de la gestión turística en relación con la calidad de vida de los habitantes de Bajo Alto, El Guabo-Ecuador. La investigación es de tipo aplicada y descriptiva, pues se trata de valorar las oportunidades que representa el turismo para una comunidad que no tiene muchas opciones a la hora de elegir las actividades económicas y productivas en la búsqueda de una mejor calidad de vida. Desde el punto de vista operacional, el estudio está sustentado en la aplicación de dos cuestionarios: por una parte a los dirigentes de la comunidad Bajo Alto, allegados a la actividad turística de la zona; y, por otro lado, a quienes la visitan en calidad de turistas. En general se logra visibilizar las necesidades principales que debe cubrir la gestión turística para convertirse en una opción real para mejorar la calidad de vida de los habitantes.

We investigate the nucleosynthesis and kilonova properties of binary neutron star (NS) merger models that lead to intermediate remnant lifetimes of ∼0.1–1 s until black hole (BH) formation and describe all components of the material ejected during the dynamical merger phase, NS remnant evolution, and final viscous disintegration of the BH torus after gravitational collapse. To this end, we employ a combination of hydrodynamics, nucleosynthesis, and radiative transfer tools to achieve a consistent end-to-end modeling of the system and its observables. We adopt a novel version of the Shakura–Sunyaev scheme allowing the approximate turbulent viscosity inside the NS remnant to vary independently of the surrounding disk. We find that asymmetric progenitors lead to shorter remnant lifetimes and enhanced ejecta masses, although the viscosity affects the absolute values of these characteristics. The integrated production of lanthanides and heavier elements in such binary systems is subsolar, suggesting that the considered scenarios contribute in a subdominant fashion to r-process enrichment. One reason is that BH tori formed after delayed collapse exhibit less neutron-rich conditions than typically found, and often assumed in previous BH torus models, for early BH formation. The outflows in our models feature strong anisotropy as a result of the lanthanide-poor polar neutrino-driven wind pushing aside lanthanide-rich dynamical ejecta. Considering the complexity of the models, the estimated kilonova light curves show promising agreement with AT 2017gfo after times of several days, while the remaining inconsistencies at early times could possibly be overcome in binary configurations with a more dominant neutrino-driven wind relative to the dynamical ejecta.
The Kelvin–Helmholtz Instability at the Boundary of Relativistic Magnetized Jets
Authors: Chow Anthony , Davelaar Jordy , Rowan Michael E. , Sironi Lorenzo
Published: July 2023

We study the linear stability of a planar interface separating two fluids in relative motion, focusing on conditions appropriate for the boundaries of relativistic jets. The jet is magnetically dominated, whereas the ambient wind is gas-pressure-dominated. We derive the most general form of the dispersion relation and provide an analytical approximation of its solution for an ambient sound speed much smaller than the jet Alfvén speed v
A, as appropriate for realistic systems. The stability properties are chiefly determined by the angle ψ between the wavevector and the jet magnetic field. For ψ = π/2, magnetic tension plays no role, and our solution resembles the one of a gas-pressure-dominated jet. Here, only sub-Alfvénic jets are unstable (

We present the analysis of two unusually red L dwarfs, CWISE J075554.14−325956.3 (W0755−3259) and CWISE J165909.91−351108.5 (W1659−3511), confirmed by their newly obtained near-infrared spectra collected with the TripleSpec4 spectrograph on the Southern Astrophysical Research Telescope. We classify W0755−3259 as an L7 very low-gravity dwarf, exhibiting extreme redness with a characteristic peaked H-band and spectral indices typical of low-gravity late-type L dwarfs. We classify W1659-3511 as a red L7 field-gravity dwarf, with a more rounded H-band peak and spectral indices that support a normal gravity designation. W1659−3511 is noticeably fainter than W0755−3259, and the rounded H-band of W1659−3511 may be evidence of CH4 absorption.
First exhaustive distribution and habitat modelling of Morimus asper (Sulzer, 1776) sensu lato (Coleoptera, Cerambycidae) in Bulgaria

Published: July 2023

Although Morimus asper, in particular the ssp. funereus, is considered as widespread throughout Bulgaria, a current national mapping of the species is missing. Thus, here we present the first exhaustive study on the distribution of M. asper in Bulgaria. Our research combined 967 georeferenced presence records from scientific publications, from the museum collection of the National Museum of Natural History-BAS, as well as authors’ and citizen scientists’ field observations. An Ecological Niche Model (ENM) was generated using software MaxEnt to identify the potential distribution of the species based on niche suitability. The potentially suitable area for the species was 26% of Bulgaria (29 059 km2). The main predictor variables in M. asper’s ENM assessed by а Jackknife test were the distance to mixed Fagus-Carpinus forests, the mean forest age, the mean tree height, the maximal temperature during the hottest month and the altitude. The percentage contribution to the model of the first two variables was also the largest – respectively 40% and 11%. The remaining variables contributed less than 10% each. Furthermore, we recommend some changes to the current species monitoring methodology to the National Biodiversity Monitoring System.

The current paper presents the first effort to organize a comprehensive review of the Invasive Alien Species (IAS) of Greece. For this purpose, a database was developed with fields of information on the taxonomy, origin, ecology and pathways of introduction of terrestrial, freshwater and marine species. Our database includes a) taxa in the Union’s list that are present in Greece, b) taxa already present in Greece and considered to be invasive, and c) taxa highly likely to enter Greece in the next 10 years and become invasive. The Database served as the starting point for the compilation of the National List of Alien Invasive Species (HELLAS-ALIENS) in compliance with the EU Regulation 1143/2014. Overall, the HELLAS-ALIENS comprises 126 species, i.e. 32 terrestrial and freshwater plant species, 14 terrestrial invertebrates, 28 terrestrial vertebrates, 30 freshwater fishes and invertebrates and 22 marine species. Terrestrial invertebrates, birds and mammals are mainly of Asiatic origin. Most of the terrestrial plants have their native geographical distribution in the Americas (North and South). Most of the freshwater invertebrates and fishes are of North American origin, while the majority of the marine species are of Indo-Pacific origin. The first records of IAS concern terrestrial plant species, and date back to the 19th century, while those in freshwater and marine ecosystems seem to have been systematically recorded some decades later. Regarding the pathways of introduction, most of the taxa arrived in Greece or are expected to arrive through escape from confinement and unaided. The majority of the terrestrial, freshwater and marine species have been evaluated as of High-risk for the indigenous biodiversity and only 3% of the species listed have been evaluated of Low-risk. Our results provide an important baseline for management and action plans, as required by the priorities set by the European Union through the Biodiversity Strategy for 2030.

Published: July 2023

Interleukin (IL)-17 and IL-23 inhibitors are both approved for the treatment of moderate-to-severe plaque psoriasis (PsO), as well as psoriatic arthritis (PsA). In the absence of head-to-head studies, it is not clear which agent is better suited to treat patients with moderate-to-severe PsO and mild PsA. During the 2022 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) conference, Dr. April Armstrong and Dr. Joseph Merola debated which of these 2 biologic classes should be used in this patient population. Armstrong argued in favor of IL-17 inhibition, whereas Merola presented reasons for IL-23 inhibition. An overview of their main arguments is described in this manuscript.
Is Axial Psoriatic Arthritis the Same as Ankylosing Spondylitis With Psoriasis: A Debate
Authors: Coates Laura C. , Deodhar Atul
Published: July 2023

During the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2022 conference, Drs. Laura Coates and Atul Deodhar debated whether axial psoriatic arthritis (axPsA) is the same as ankylosing spondylitis (AS) with psoriasis. Dr. Coates argued that AS represents a spectrum of disease and that axPsA can be considered within that spectrum. Dr. Deodhar argued that axPsA and AS are 2 different diseases, using construct, content, face, and criterion validity. Their main arguments are described in this manuscript.

People with psoriasis (PsO) are at increased risk of developing psoriatic arthritis (PsA). Screening patients with PsO for PsA may be helpful in diagnosing PsA early. Dermatologists play a role in assessing their patients with PsO for musculoskeletal symptoms and referring them to a rheumatologist for diagnosis and treatment.

Published: July 2023

In this article, the maximum likelihood and Bayes inference methods are discussed for determining the two unknown parameters and specific lifetime parameters of the Nadarajah-Haghighi distribution, such as the survival and hazard rate functions, with the inclusion of ranked set sampling and simple random sampling. The estimated confidence intervals for the two parameters and any function of them are developed based on the Fisher-information matrix. Metropolis-Hastings algorithm and Lindley-approximation are used for generating the Bayes estimates and related highest posterior density credible ranges for the unknown parameters and reliability parameters under the presumption of conjugate gamma priors. A Monte-Carlo simulation study and a real-life data set have been used to assess the efficacy of the proposed methods.
