A nyelvvizsga-monopóliumtól a nyelvvizsgasorompóig. A nyelvvizsga a nyomtatott sajtóban 2000 és 2019 között
Authors: Vajnai Viktória
Published: May 2023

A nyelvvizsga kérdése Magyarországon évtizedek óta kiemelt szerepet játszik az oktatással és továbbtanulással összefüggésben, és ennek köszönhetően az oktatás világán túlmutató társadalmi diskurzus és viták témája. Ez a sajtóelemzés a magyar nyomtatott sajtóban 2000 és 2019 között megjelent, a nyelvvizsgához kapcsolódó megszólalásokat és véleményeket elemzi azzal a céllal, hogy a nyelvvizsgához kapcsolódó társadalmi diskurzus elemeit és összefüggéseit feltárja és értelmezze. Az elemzésbe a 168 óra, az Élet és Irodalom, a Heti Válasz, a Magyar Demokrata, a Figyelő, a Köznevelés és a Pedagógusok Lapja összesen 53 cikke került. A többlépéses diskurzuselemzési folyamat három elkülöníthető, de egymással szoros összefüggésben álló témakört eredményezett: (1) a nyelvvizsga jelentése, célja és használata, (2) a nyelvtudás és nyelvtanítás kérdése, (3) vesztesek és nyertesek – felelősök és áldozatok. Az elemzés emellett nemcsak a nyelvvizsga, a nyelvtudás és a nyelvtanulás lehetséges társadalmi narratíváira világít rá,hanem az ezekkel összefüggésben lévő társadalmi kérdésekre és meggyőződésekre is, mint a köz- és felsőoktatásproblémái, a problémák vélt okai, az oktatás- és társadalompolitika célja, hatása, nyertesei és vesztesei.

Published: May 2023

Alogliptin (ALG) benzoate is an oral hypoglycemic drug that works as a DPP-4 inhibitor to prevent incretin degradation. Forced stability studies use high temperatures to decompose drugs and estimate their behavior at low temperatures. We aimed to evaluate the thermal stability of ALG using two techniques: isothermal thermogravimetry (TGA) and degradation in an oven followed by liquid chromatography (LC-PDA) analysis. ALG was subjected to 150, 155, 160, 165, and 170 °C up to 10% of mass loss in isothermal TGA. In the oven, the drug was submitted to 130, 140, 150, 155, 160, and 170 °C. Kinetic parameters were calculated with the Arrhenius model. ALG followed zero-order kinetics, in which the degradation rate did not depend on reagent concentration. Activation energy ranged from 31.0 to 35.9 kcal mol-1. The degraded drug was less toxic in a cytotoxicity assay in CRIB cells than the undegraded drug. The TGA method is faster and more practical than the oven followed by LC-PDA, and the data present a correlation. Here we described the kinetic parameters of ALG degradation, improving the knowledge about the drug and assisting in developing new formulations from the drug.
Online-Offline Competition with Heterogeneous Consumers: An Example for No Existence of Pure Strategy Nash Equilibrium
Authors:   Texas A&M University, Ford Weixing , Han Haipeng ,   Tsinghua University, Zheng Jie ,   Tsinghua University
Published: May 2023

Existing literature on competition between online and offline firms has focused on market conditions that guarantee the existence of a pure strategy Nash equilibrium. In this note, by constructing a concrete example, we provide a first attempt to show that the equilibrium existence result does not necessarily hold when consumers’ preferences are heterogeneous. Specifically, we consider the competition between one online firm and several offline firms in a market organized as a Salop model, where consumers’ preferences have a binary distribution. We identify a boundary scenario where the type distribution is binary with one type of consumer loyal to online shopping and the other type loyal to offline shopping. We show that there is no pure strategy Nash equilibrium for this boundary scenario, which indicates that the market may not be stable under such conditions. Our study contributes to a better understanding of the equilibrium existence conditions for the online versus offline retail competition.

The subject of this paper is a non-autonomous linear quadratic case of a differential game model with continuous updating. This class of differential games is essentially new where it is assumed that, at each time instant, players have or use information about the game structure defined on a closed time interval with a fixed duration. During the interval information about motion equations and payoff functions of players updates. It is non-autonomy that simulates this effect of updating information. A linear quadratic case for this class of games is particularly important for practical problems arising in the engineering of human-machine interaction. Here we define the Nash equilibrium as an optimality principle and present an explicit form of Nash equilibrium for the linear quadratic case. Also, the case of dynamic updating for the linear quadratic differential game is studied and uniform convergence of Nash equilibrium strategies and corresponding trajectory for a case of continuous updating and dynamic updating is demonstrated.

This thesis is devoted to the spread of virus in human society. First, we modified the original basic epidemiological model, and divide the system into M different types. The optimal control problem is formulated for the changes of compartments in different states. The total cost is then minimized, the Pontryagin maximum principle is used to solve this nonlinear optimal control problem. Next, we prove that the optimal policy has the simple structure. Finally, we fit the propagation process of this model using Matlab. Consider the situation where there are only two types of virus in the system, and compare the two types of virus appear at the same time and at different times.

Published: May 2023

An empirically meaningful theory of dynamic games has to incorporate real-life phenomena. Durable strategies, which effects last for a period of time, are prevalent in real-life situations. Revenue generating investments, toxic waste disposal and purchase of durable goods are common examples of durable strategies. This paper first provides a review on durable-strategies dynamic game theory. A practically relevant advancement - random horizon durable-strategies dynamic games - yielding novel results in durable-strategies dynamic games theory is then presented. Dynamic optimization theorem, game formulations and HJB equations are derived. An illustrative example is provided. The theory and solution mechanism of durable-strategies cooperative dynamic games are also discussed.

Authors: Chauhan Surendra Singh , Dikshit Prabhat Kumar Singh
Published: May 2023

The present study aims to investigate the use of response surface methodology (RSM) modelling and experimental investigation for the optimization of lead(II) adsorption onto spent tea grains (STG). Independent process variables were optimized and found to be in the range of 38.75 mg/l (initial concentration), 5.20655 (pH), 119.32 rpm (stirring speed), and 3.25 g/l (STG dose) for a contact time of 135.05 min. The optimum adsorption capacity was found to be 8.9087 mg/g through RSM modelling with a maximum of 18.146 mg/g. The batch study was performed by varying different parameters: pH (2.0–7.0), initial concentration (5–50 mg/l), dose (0.1–1 g/100 ml), contact time (15–180 min), and stirring speed (30–200 rpm). The characterization STG was done by proximate and ultimate analysis, FTIR spectroscopy, XRD analysis, thermogravimetric analysis (TGA), and SEM-EDX. By fitting equilibrium data onto Langmuir isotherm model, the maximum adsorption capacity was found to be 24.272 mg/g. The optimum pH found for lead(II) adsorption onto STG was 5. At optimum conditions, the maximum removal efficiency of STG for lead(II) ions’ adsorption is 94.33%. Based on the findings it is safe to conclude that the STG could be used as a potential adsorbent.

Published: May 2023

Introduction:

Respiratory incentive, an instrumental technique used to increase transpulmonary pressure, is indicated when patients present decreased volumes and capacities, a condition presented by patients with acute phase coronavirus infection and patients with pulmonary sequelae post COVID-19. Some studies recommend including respiratory incentives in managing COVID-19 patients because of its benefits and limited risk. The objective of this exploratory review was to describe and present the current evidence of the effectiveness of IR in improving pulmonary function in adult patients with acute and post COVID-19.

Methods:

An exploratory review was performed. An extensive search was made in databases such as BVS (MEDLINE-LILLACS-IBECS), PubMed, OVID, Scielo, PEDro, and EBSCO, the checklist recommended by PRISMA was used and was based on the Johanna Briggs method (JGB), initially conceived by Arksey and O "Malley. To assess the quality of the studies, we used the PEDro Scale, which evaluates the methodological quality of the clinical designs.

Results:

In this exploratory review, 4 studies published between 2019 and 2022 were identified re-lated to the use of the respiratory incentive in COVID-19 and post COVID-19. The evidence re-viewed identified that the respiratory incentive was used in the acute phase of the disease and post COVID-19, improvements in lung function such as FVC and FEV1, clinical parameters such as ox-ygen saturation, dyspnea and anxiety were obtained.

Conclusion:

The studies identified in this review describe that IR favors the increase of FVC and
FEV1, with occasional benefits in improving dyspnea and oxygen saturation.
Effect of Nanostructure Morphology and Concentration on the
Piezoelectric Performance of Flexible Pressure Sensor based on PVDFTrFE/
Nano-ZnO Composite Thin Film
Authors: Liu Yurong , Zeng Xiaolong , Zhu Lin , Wang Cong , Geng Kuiwei , Yao Ruohe
Published: May 2023

Background:

The development of high-performance piezoelectric pressure sensors with
outstanding sensitivity, good linearity, flexibility, durability, and biocompatibility is of great significance
for smart robotics, human healthcare devices, smart sensors, and electronic skin. Thus,
considerable progress has been achieved in enhancing the piezoelectric property of PVDF-TrFEbased
composite pressure sensors by adding various ZnO nanostructures in PVDF-TrFE polymer
acting as a nucleating agent and dielectric material.

Aims:

In this work, flexible pressure sensors with a sandwich structure based on PVDFTrFE/
nano-ZnO composite sensing film were fabricated using a simple spin-coating method and
post-annealing process, while electrospinning and high-voltage polarization processes were not
adopted.

Methods:

Poly (vinylidene fluoride-trifluoroethylene) (PVDF-TrFE)/nano-ZnO composite films
were prepared via spin coating to fabricate flexible piezoelectric pressure sensors. ZnO nanoparticles
(ZnO NPs), tetrapod ZnO (T-ZnO) and ZnO nanorods (ZnO NRs) were used as nano-fillers
for piezoelectric PVDF-TrFE, to enhance the beta-crystal ratio as well as the crystallinity of
PVDF-TrFE. The structural and surface morphologies of the composite films were investigated
using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning
electron microscopy (SEM).

Results:

Among three different types of ZnO nanostructures with a concentration range (0-7.5
wt%), the sensor with 0.75 wt% ZnO NRs nanofiller exhibits a maximum output voltage of 1.73 V
under an external pressure of 3 N and a maximum sensitivity of 586.3 mV/N at the range of 0-3 N.
Further, the sensor can generate a clear piezoelectric voltage under bending and twisting deformation
as well as compression and tensile deformation.

Conclusion:

To summarize, the addition of different concentrations of nano-ZnO can remarkably
improve the piezoelectric performance of the composite sensor, and ZnO NRs can achieve better
piezoelectric properties of the sensor as compared to ZnO NPs and T-ZnO. In addition, the sensor
with 0.75 wt% ZnO NRs as nanofiller has the highest piezoelectric response, which is about 2.4
times that of the pure PVDF-TrFE sensor. It is demonstrated that the sensor has great potential
applications in wearable health monitoring systems and mechanical stress measurement electronics.

Patients with Bone Metastasis
Authors: De Feo Maria Silvia , Frantellizzi Viviana , Di Rocco Arianna , Farcomeni Alessio , Matto Antonio , Marongiu Andrea , Nuvoli Susanna , Spanu Angela , De Vincentis Giuseppe
Published: May 2023

Background:

Bone metastatic involvement represents a leading cause of death in patients
with advanced breast cancer (BC). At present, it is not clear whether the bone metastatic
load might impact Overall Survival (OS) in patients with bone metastatic BC at diagnosis. For this
purpose, we used the Bone Scan Index (BSI), which is a reproducible and quantitative expression
of tumor load observed at bone scintigraphy.

Objective:

The aim of this study was to associate BSI with OS in bone metastatic BC patients.

Methods:

In this retrospective study, we enrolled BC patients with bone metastases at the scintigraphic
bone scan performed for staging purposes. The BSI was calculated through the DASciS
software, and statistical analysis was carried out. Other clinical variables relevant to OS analysis
were taken into account.

Results:

Of a total of 94 patients, 32% died. In most cases, the histotype was ductal infiltrating
carcinoma. The median OS from diagnosis was 72 months (CI 95%: 62-NA). The univariate analysis
with COX regression showed that only hormone therapy significantly correlates with OS (HR
0.417, CI 95%: 0.174-0.997, p < 0.049). As concerning BSI, the statistical analysis showed that it
does not predict OS in BC patients (HR 0.960, 95% CI: 0.416-2.216, p < 0.924).

Conclusion:

Although the BSI significantly predicts OS in prostate cancer and in other tumors, we
observed that the metastatic load of bone disease has not a key role in prognostic stratification in
our population.
Factors Influencing the Answerability and Popularity of a Health-Related Post in the Question-and-Answer Community: Infodemiology Study of Metafilter (Preprint)
Authors: Yang Jinqing , Liu Zhifeng , Wang Qicong , Lu Na
Published: May 2023

BACKGROUND

The web-based health question-and-answer (Q&A) community has become the primary and handy way for people to access health information and knowledge directly.

OBJECTIVE

The objective of our study is to investigate how content-related, context-related, and user-related variables influence the answerability and popularity of health-related posts based on a user-dynamic, social network, and topic-dynamic semantic network, respectively.

METHODS

Full-scale data on health consultations were acquired from the Metafilter Q&A community. These variables were designed in terms of context, content, and contributors. Negative binomial regression models were used to examine the influence of these variables on the favorite and comment counts of a health-related post.

RESULTS

A total of 18,099 post records were collected from a well-known Q&A community. The findings of this study include the following. Content-related variables have a strong impact on both the answerability and popularity of posts. Notably, sentiment values were positively related to favorite counts and negatively associated with comment counts. User-related variables significantly affected the answerability and popularity of posts. Specifically, participation intensity was positively related to comment count and negatively associated with favorite count. Sociability breadth only had a significant impact on comment count. Context-related variables have a more substantial influence on the popularity of posts than on their answerability. The topic diversity variable exhibits an inverse correlation with the comment count while manifesting a positive correlation with the favorite count. Nevertheless, topic intensity has a significant effect only on favorite count.

CONCLUSIONS

The research results not only reveal the factors influencing the answerability and popularity of health-related posts, which can help them obtain high-quality answers more efficiently, but also provide a theoretical basis for platform operators to enhance user engagement within health Q&A communities.

Authors: Wu Yueze
Published: May 2023

Since the commencement of the New Budget Law in 2015, China provincial governments was given the legal rights to issue Local Government Bonds, which has played a significant role in revealing local indebtedness that was built up over the years. The rapid infrastructure developments have brought up respective debt levels in various levels of governments, and there exist strong concerns on whether provinces with poor development levels are on the edge of financial distress. In addition, it is also unclear on the relationship between local economic development and high debt levels. This research is an attempt to answer that question, and provide observations and analysis based on past local debt data. In summary, this research used provincial LGB data and fiscal income statistics to establish relationships with local debt burden, governors’ financing decisions, as well as the LGB issuance limit setting process. Compared to existing research, updated provincial level data will be used (2015-2021).

Authors: Meghanath Mudavath , Danish Dr. Muhammad
Published: May 2023

Abstract: One of Karnataka, India's cities with the fastest population growth is Bengaluru. Inadequate walking and cycling infrastructure made people choose personal vehicles over sustainable transport options more often while the city focused on infrastructure to reduce traffic. By 2035, the Comprehensive Mobility Plan (CMP) Bengaluru (2020) seeks to expand public transportation's mode share from 42% to 70%. In order to reach this goal, it is crucial to guarantee that more people have easy access to public transport options in addition to increasing the mass transit infrastructure, as increased access to PT tends to encourage more people to utilise it rather than their own motorised vehicles. To this end, the city of Bengaluru has developed a Transit Oriented Development (TOD) policy. Walkability, Cyclability, Quality of Public Transport Infrastructure, Safety Infrastructure at Junctions, Quality of Intermediate Public Transport, and Public Amenities that Support the Uptake of Sustainable Mobility Modes are the parameters taken up as part of. The study region of Chikkabanawara is situated on the outskirts of the city of Bangalore and has the distinctive feature of greenfield development with prominence of educational institutions, commercial businesses, residential areas, and high-rise flats in the 500-meter buffer zone.

Super-Resolution of Images using Contrastive Self-Learning
Authors: Meher Gourav , Mandhani Ashutosh , Akilandeshwari Dr. P.
Published: May 2023

Abstract: Super-resolution (SR) techniques aim to enhance the resolution and quality of low-resolution images. In recent years, deep learning-based approaches have achieved remarkable success in this field. However, training deep SR models often requires large-scale datasets and computationally expensive operations, limiting their practicality. Different approaches have been proposed to tackle computation and time constraints. Our novel approach involves a combination of knowledge distillation and contrastive loss function to train a compact and efficient contrastive self-distillation (CSD) model. In the framework, a teacher network is initially trained on a large dataset using a traditional supervised learning approach. The teacher network learns to generate high-resolution images from low-resolution inputs. Subsequently, a student network is initialized with the same architecture as the teacher network but with fewer parameters. The student network is then trained to mimic the behavior of the teacher network by utilizing a contrastive loss. The contrastive loss is formulated by constructing positive and negative pairs of low-resolution and high-resolution image patches. The proposed CSD method achieves competitive performance compared to state-of-the-art SR methods while requiring significantly fewer parameters and computational resources. Furthermore, it demonstrates improved generalization capability by effectively reconstructing details in real-world images.

Authors: Neelaveni Dr. R. , . Abhinav , . Sahas
Published: May 2023

Abstract: Our increasingly connected world continues to face an ever-growing amount of network-based attacks. Intrusion detection systems (IDS) are essential security technology for detecting these attacks. Although numerous machine learningbased IDS have been proposed for detecting malicious network traffic, most have difficulty properly detecting and classifying the more uncommon attack types. The research in Cyber Security has raised the need to address the cybercrimes that have caused the requisition of intellectual properties such as the breakdown of computer systems and impairment of important data compromising the confidentiality authenticity and integrity of the user. Considering these scenarios, securing the computer systems and the user using an Intrusion Detection System (IDS) is essential. The performance of IDS was studied by developing an IDS dataset consisting of network traffic features to learn the attack patterns. Intrusion detection is a classification problem wherein various Ensemble Learning (ML) and Data Mining (DM) techniques are applied to classify the network data into normal and attack traffic. Moreover, the types of network attacks changed over the years, so updating the datasets used for evaluating IDS is necessary.

Published: May 2023

Due to human activities, the overabundance of regional nitrogen/
phosphorus (N/P) has a huge impact on ecological environment worldwide.
It’s quite necessary to comprehensively understand the human-induced N/P
inputs and spatiotemporal variations of nutrients in the river. As the
adjustment to the spatial structure of Beijing, the Beijing’s sub-center
is an important strategic position in promoting the coordinated
development of Beijing-Tianjin-Hebei. In this study, the dynamic changes
of NH N and TP from 2012 to 2022 were analyzed, then
the net anthropogenic N input (NANI), net anthropogenic P input (NAPI)
was estimated in the Beijing’s sub-center. The results showed that both
NH N and TP had an overall downward trend with a
three-stage pattern. The NANI and NAPI declined from 5.68 x 10
kg∙km ∙a
and 0.95 x 10 kg∙km ∙a
to 0.78 x 10 kg∙km
∙a and 0.15 x 10
kg∙km ∙a ,
respectively. The chemical fertilizers input accounted for the largest
part at 53%~81% of NANI and 49%~80%
of NAPI. There were high values of N and P input in the southeast of
Tongzhou, and the fluxes of N and P were positively correlated with the
inputs of anthropogenic N and P in the Chaobai River Basin and the
Beiyun River Basin. This study would provide the foundation for setting
priorities and enacting more targeted N/P management strategies in the

Background: The outbreak of SARS-COV-2 has necessitated the
implementation of urgent measures to suppress the transmission of the
virus, including the mandatory public use of masks, regular hand
washing, and social distancing. These measures may also be effective in
reducing other respiratory infectious deseases, such as Influenza and
severe acute respiratory illness. Therefore, the aim of the study was to
estimate the prevalence of respiratory pathogens among SARS-CoV2
non-reactive patients, admitted in healthcare facilities in the context
of COVID-19 management. Material and Method: From February to July 2021,
a total number of 167 nasopharyngeal swabs from adults fitting the case
definition of COVID-19 syndrome and negative to SARS-CoV-2 were enrolled
from seven regional sites in Morocco.All samples were subject to a
multiplexed nucleic acid test intended for the simultaneous detection
and differentiation of 22 respiratory pathogens. Results: Our study
showed that overall, theprevalence of respiratory pathogens was 43%
(n=72). The main detected pathogens were typed as Human Rhinovirus (HRV)
(38%), Human Coronavirus OC43 (37%) and Human Parainfluenza3 (HPIV3)
(12%). Conclusion: Our findings support the notion that during the
SARS-CoV2 pandemic, the detection of Influenza A/B, Human
Metapneumovirus, and Respiratory Syncytial Virus all declined.
Meanwhile, there was a noticeable increase in HRV and HCoV OC43. The
dynamics of airborne transmission and epidemic patterns were thus
assumed to be greatly improved by the SARS-CoV-2 prophylactic measures.
These findings could be useful in guiding future prevention and
management of respiratory illnesses.

Compound/silicon heterojunction (SCH) solar cells have been widely
studied due to the low parasitic absorption of the window layer, high
short-circuit current, and simple preparation process. So far, most
reported SCH solar cells are small-area devices. By depositing MoO
hole transport layer using hot-wire
oxidation-sublimation deposition technique and employing a front-contact
back-junction cell architecture, the large-area SCH solar cells are
successfully fabricated on M6 (166 mm) n-type silicon wafers. Indium
cerium oxide (ICO) film with the optimal thickness of about 110 nm is
inserted between MoO and Ag. The ICO/Ag stack
functions well as a back reflector and is beneficial for increasing the
short-circuit current density, reducing the contact resistance, and
improving the device stability. A power conversion efficiency of 21.59%
is achieved on the champion SCH solar cell with the device area of
274.15 cm .

Authors: Pellis Stergios
Published: May 2023

In this paper it will be presented the theoretical value of the Gravitational constant. From the dimensionless unification of the fundamental interactions we will find the formulas for the Gravitational constant. From these equations it will be calculated the theoretical value of the Gravitational constant. This value is very close to the CODATA recommended value of gravitational constant and two experimental measurements from a research group announced new measurements based on torsion balances.
Modeling N-linked Glycosylation: Advances and Challenges in Predicting Glycan Structures during Biomanufacturing
Authors: Singh Sumit K. , Khan Sahil , Joshi Aryaman
Published: May 2023

N-linked glycosylation is a process in which glycans are added to the
nitrogen atom of the asparagine amino acid of the protein. It has a
significant impact on protein function, stability, and immunogenicity.
Modelling N-glycosylation is a complex task due to the diversity of
glycan structures, the variability of glycosylation sites, and the
heterogeneity of the glycosylation process. Various computational models
have been developed to predict N-glycosylation patterns and understand
the relationship between glycan structures and biological function.
These models use different methods, such as molecular dynamics
simulations, protein engineering, and machine learning, to study the
glycosylation process and predict the glycan structures. Understanding
the factors influencing N-glycosylation can provide insights into
developing therapeutic interventions for diseases like inflammation,
viral infections, and cancer. This paper reviews the current state of
modelling N-glycosylation and highlights recent advances in this field.

Published: May 2023

Aim: This study aimed to use the micro-computed tomography to
evaluate the interfacial adaptation and the presence of gaps of NeoMTA
Plus, BioRoot RCS, and MTA in the root-end cavities.
Methodology: Thirty standardized bovine roots measuring 15 mm
in length were selected. Chemical-mechanical preparation was performed
up to instrument #80 and obturation with the cold lateral compaction
technique with cement based on zinc oxide and eugenol. The roots were
kept at 37º C for seven days. Afterward, apicectomy of the apical 3mm
and a root-end filling cavity was performed at 3mm depth. Micro-computed
tomography (micro-CT) was performed to measure the volume of the
retroactivity. The roots were divided by stratified randomization into
three groups according to the retro-end filling material: NeoMTA Plus,
BioRoot RCS, and MTA. A new micro-CT was performed to assess the
presence of voids in the root-end filling material and between it and
the canal wall. One-way ANOVA and Tukey tests were performed using the
BioEstat 4.0 program. Results: There was no difference in the
initial volume values of the root-end cavities (P > 0.05).
After the insertion of root-end filling materials, the most significant
volumes of voids were observed in the NeoMTA Plus group (P <
0.05), with no difference for the BioRoot RCS and MTA Angelus groups (P
> 0.05). Conclusion: Micro-computed tomography
showed that MTA and BioRoot RCS have better interfacial adaptation and
presented fewer number of gaps than NeoMTA Plus when used as root-end
filling materials.

Published: May 2023

Skin diseases are often accompanied by physical, emotional and social problems, which may negatively impact health-related quality of life and result in skin-related distress. It is essential to identify patients with skin-related distress within the short time-window of an outpatient dermatological visit. Therefore the one-question screening tool, the Distress Thermometer adjusted for skin conditions, was validated in a cross-sectional questionnaire study. In 2 medical centres in Amsterdam, 214 patients with a chronic skin disease were invited to complete the Distress Thermometer and additional health-related quality of life questionnaires. To validate the Distress Thermometer, the Skindex29 was used as gold standard. To test test–retest reliability, the questionnaires were answered at 2 different time-points. Severely impaired health-related quality of life was present in 30% of respondents according to the Skindex29 using a cut-off score of 44. Receiver operating characteristic curve analyses yielded an area under the curve of 0.813 (standard error 0.04, 95% confidence interval 0.74–0.89). A cut-off score ≥ 4 on the Distress Thermometer provided the optimal ratio of sensitivity (90.7%) to specificity (56.1%). Therefore, for general practice, a cut-off score of ≥ 4 on the Distress Thermometer is advised. The Distress Thermometer seems to be a rapid, valid and reliable screening tool for identifying skin-related distress in patients with a chronic skin disease in the outpatient dermatology setting.
From Anthropocentrism to a Cosmopolitan Biocentrism: Reflections on Animal Ethics
Authors: Viviani Franco
Published: May 2023

The reasoning about the right and wrong ways to consider, use and treat animals is the focus of animal ethics. For a long time, animal rights have largely escaped anthropological attention. Only recently, however, thanks to new perspectives its assignment is to go beyond the human. This is because we must change the inner assumptions of our basic concepts on human and non-human ethics if we want to deconstruct the human/animal dichotomy. The author reflects on the different theories currently found in literature and the fact that none of them expressed so far are completely accepted, probably due to the different dispositions towards the term ethics. Some of the various theoretical alternatives recently proposed by Authors belonging to different disciplines are discussed in the paper.
Meditation for Human Mind and Brain: Findings from Functional Neuroimaging Investigations
Authors: Bista Suman
Published: May 2023

Meditation is generally described as being in the present moment or being alert in the present moment, instead of constantly struggling to change or to become. Meditation is an essential part of Yoga philosophy and the seventh limb of Astanga Yoga described by sage Patanjali in the ancient text Patanjali Yoga Sutra. Yoga including meditation, is an ancient technique invented to unite the individual consciousness with the universal consciousness, however, scientific studies have demonstrated the vast health advantages associated with it. Mindfulness as a non-judgmental awareness of the present-moment is also a part of yoga philosophy, however, most of the mindfulness practices those are being practiced in modern days are also rooted in Buddhist philosophy. Some well-known meditation techniques are Buddhist meditations, Hindu meditations, Chinese meditations, Christian meditation, Islamic meditations, Guided meditations etc. Meditation influences brain systems involved in attention, awareness, memory, sensory integration, emotion regulation, and higher-order cognitive functions. Meditation has also been found to be very effective in relieving stress, regulating emotions and promoting mental health. A significant increase in grey matter volume was found in the meditators as compared to non-meditators. The larger grey matter volume overall, and with regional enlargement in several right hemispheric cortical and subcortical brain regions are associated with sustained attention, self-control, compassion and interoceptive perception. Several functional neuroimaging studies showed that some brain regions are recruited consistently across different meditation techniques including insula, pre/supplementary motor cortices, dorsal anterior cingulate cortex, and frontopolar cortex.
