NUOVE COSTRUZIONI DELL’IMMAGINARIO IDENTITARIO – STUDIO DI CASO
Authors: NEȘU Nicoleta 
Published: April 2023

Some New Constructions of the Identitary Imaginary – A Case Study. The starting point of the present research is based mainly on the experience of working with young people of Romanian origin, more specifically, university students, who live and study abroad, and concerns their self-perception at the level of their identy and some possible characteristics of their imaginary identity. The theoretical aspect of this research can be divided in two as follows: a general part, focusing on the theory of migration, the ethnic language/heritage language and the new identity typologies resulting from the current economic and political state of affairs and a second part, structured according to the coordinates of the collective and personal imaginary. The practical aspect is based, on the one hand, on the answers these students offered to some questionnaires administered for a period of seven years and, on the other hand, on a series of compositions written by the students in the form of "open letters to Romania", as an assignment for their Romanian language course on the occasion of the National Day of Romania, collected over the last three years. I will try to analyse both the answers to the questionnaires and their "letters", from the perspective of the above mentioned theory, with the explicit purpose of extracting some characterisctics.
Noi construcții ale imaginarului identitar – studiu de caz. Punctul de plecare al cercetării de față îl constituie, în principal, experiența de lucru cu tineri studenți de origine română care se află în situația de a locui, trăi și studia în afara granițelor românești, modul lor de a se autopercepe la nivel identitar și posibilele caracteristici ale imaginarului lor identitar. Aspectul teoretic al acestei cercetări este unul extrem de generos și l-aș divide într-o parte generală, având în centru teoria migrației, a limbii etnice/heritage language și a noilor tipologii identitare rezultate în urma unui necesar proces de re-evaluare datorat modificărilor situației politice și sociale la nivel mondial și o parte structurată pe coordonate ale imaginarului – colectiv și personal. Aspectul practic are la bază, pe de-o parte, răspunsurile acestor studenți la niște chestionare administrate lor în ultimii șapte ani și, pe de altă parte, o serie de compoziții scrise ale studenților sub forma unor scrisori deschise către România, redactate de către ei în cadrul cursului de limba română cu ocazia Zilei Naționale a României, în ultimii trei ani. Voi analiza atât răspunsurile la chestionare, cât și mesajele transmise prin aceste scrisori din perspectiva teoriei care face obiectul primei părți a cercetării noastre, cu finalitatea explicită de a extrage o serie de caracteristici structurante.

Metrics for Marketing Decisions: Drivers and Implications for Performance
Authors: Mintz Ofer 
Published: April 2023

Abstract
Marketers are using metrics to diagnose, coordinate and monitor customer relationships and marketing efforts, set benchmarking goals to guide marketing implementation, and communicate the results of marketing outcomes with internal and external stakeholders.
Even if the number of available metrics is striking, some studies found support for the idea that the more metrics managers employed for their decisions, the better the marketing performance. Studies by the author also showed that using non-financial marketing metrics, such as awareness, willingness to recommend and loyalty, seemed to be associated with better marketing mix performance outcomes than using financial metrics, such as target volume, NPV and net profit. Developing a customer-centric organizational structure encourages managers to consider and develop a greater reliance on metrics.
Thermodynamic Stability and Anion Ordering of Perovskite Oxynitrides
Authors: Young Samuel , Chen Jiadong , Sun Wenhao , Goldsmith Bryan , Pilania Ghanshyam 
Published: April 2023

Perovskite oxynitrides (PONs) are a promising class of materials for applications ranging from catalysis to photovoltaics. However, the vast space of single PON materials (ABO3–xNx}) has yet to be fully explored. Additionally, the community needs guidelines that relate PON chemistry and anion ordering to stability to better understand how to design PON materials that resist corrosion and decomposition under operating conditions. Screening this materials space requires identifying candidate PON materials that will be stable under operating conditions, which in turn requires methods to evaluate each material's stability. Here we predict the stability of single PON materials using a four-step approach based on density functional theory modeling: (I) enumerate viable cation pairs, (ii) select an energetically favorable prototypical anion ordering, (iii) compute each PON's free energy above the thermodynamic convex hull, and (iv) generate computational Pourbaix diagrams to determine allowable ranges of electrochemical operating conditions. A critical part of our approach is determining a prototypical stable anion ordering for both ABO2N and ABON2 stoichiometries across a variety of A- and B-site cations. We demonstrate a stable anion ordering containing a high degree of cis ordering between B cations and minority-composition anions. We predict 85 stable and 109 metastable PON compounds, with A∈{La, Pb, Nd, Sr, Ba, Ca} and B∈{Re, Os, Nb, Ta} forming cation pairs that lead to stable PONs less than 10 meV/atom above the thermodynamic convex hull. Computational Pourbaix diagrams for two stable candidates, CaReO2N and LaTaON2, suggest that not all compounds with zero energy above the thermodynamic convex hull can be easily synthesized.
The role of polymorphism of candidate genes in the development of knee osteoarthritis in men of the Central Chernozem region of Russia
Authors: Novakov V. B. , Novakova O. N. , Churnosov M. I. 
Published: April 2023

Knee osteoarthritis (OA) is a disease resulting from the interaction of many local and systemic risk factors, among which an important role is played by genetic (hereditary) factors. This disease affects both men and women, but there are certain differences in the development and progression of the disease in different sexes.Aim. To study associations of polymorphic loci of candidate genes with the risk of developing knee ОА in the male population of the Central Chernozem region of Russia.Material and Methods. The study sample included 410 men (208 patients with knee OA and 202 controls). Ten polymorphic loci of candidate genes were genotyped: rs2820436 and rs2820443 LYPLAL1, rs3771501 TGFA, rs11177 GNL3, rs6976 GLT8D1, rs1060105 and rs56116847 SBNO1, rs6499244 NFAT5, rs34195470 WWP2, rs143384 GDF5. The study of associations of polymorphic genetic loci with the development of the disease was carried out by the method of logistic regression, taking into account covariates (age, BMI). The MB-MDR method was used to study intergenic interactions of polymorphisms associated with the disease.Results and Discussion. It was found that nine out of ten polymorphic loci of candidate genes (with the exception of rs6976 GLT8D1) are associated with the formation of knee OA in men in four models of interlocus interactions (pperm ≤0.024). The rs3771501 TGFA polymorphic locus (included in three of the four most significant models of gene-gene interactions) demon- strates the greatest contribution to the development of the disease in men. Independent effects of the studied polymorphic loci of candidate genes in the development of knee OA in men have not been identified (р > 0,05).Conclusion. Polymorphic loci rs2820436 and rs2820443 LYPLAL1, rs3771501 TGFA, rs11177 GNL3, rs6976 GLT8D1, rs1060105 and rs56116847 SBNO1, rs6499244 NFAT5, rs34195470 WWP2, rs143384 GDF5 involved in the development of knee osteoarthritis in men in four models of intergenic interactions. Among the studied loci, rs3771501 of the TGFA gene has the greatest contribution to disease susceptibility.

Hernia de Amyand encarcelada, revisión de la literatura y reporte de un caso en una institución de tercer nivel en Bogotá
Authors: Villarreal Ricardo , Jaspe Carlos Luna , Cabrera Luis Felipe , Vinck Eric 
Published: April 2023

Introducción. La hernia de Amyand es una hernia inguinal que contiene el apéndice cecal normal o en un estado de apendicitis aguda. Fue descrita por primera vez en 1735 por Claudius Amyand. La apendicitis aguda probablemente se debe a una obstrucción extraluminal generada por aumento de la presión en el cuello herniario que limita el flujo sanguíneo, en lugar del aumento de la presión intraluminal que se presenta en la apendicitis no asociada con hernias inguinales. Esto resulta en inflamación y proliferación bacteriana, y el apéndice cecal se torna más vulnerable al trauma.
Métodos y resultados. Se presenta y analiza, clínica y quirúrgicamente, un caso de hernia de Amyand manejado en el servicio de cirugía general de una institución de tercer nivel de Bogotá; además, se hace una revisión de la literatura científica. El abordaje quirúrgico difirió del propuesto en la guía de manejo de Losanoff y Basson y, sin embargo, se obtuvieron resultados exitosos.
Discusión. La hernia de Amyand es una entidad quirúrgica rara, la cual representa un reto diagnóstico y terapéutico, ya que se presenta con características que varían según dos procesos patológicos simultáneos: la hernia inguinal y la apendicitis aguda, cuando esta está presente. El abordaje quirúrgico depende de los hallazgos intraoperatorios, como perforación del apéndice cecal, fístula o pelviperitonitis. Por lo tanto, decidir cuál abordaje quirúrgico es el más apropiado depende de los hallazgos y las preferencias del cirujano.
Conclusiones. El tratamiento con apendicectomía, reparo del defecto herniario con malla o ambos, ha suscitado discusión entre los cirujanos por muchos años. Las diferencias de opiniones sobre la técnica quirúrgica más apropiada se deben, entre otras cosas, a la incidencia baja de la hernia de Amyand y a las preferencias quirúrgicas de cada cirujano; el mejor abordaje quirúrgico todavía está en discusión. Sin embargo, la apendicectomía está contraindicada en ciertos pacientes cuando no existe inflamación y, cuando está presente, el uso de la malla todavía es controversial. Por lo tanto, cada reporte de hernia de Amyand y su tratamiento es importante, pues ofrece conocimiento sobre la técnica quirúrgica más apropiada para esta entidad.

Published: April 2023

Finite element method is the most widely numerical technique used in engineering field. Through the study of behavior of concrete material properties, various concrete constitutive laws and failure criteria have been developed to model the behavior of concrete. A feature of the Finite Element program (ATENA) is used in this study to model the behavior of UHPC corbel under concentrated load only. The Finite Element (FE) model is followed by verification against experimental results. Some variable effects on the shear capacity of the UHPC corbels are also demonstrated in a parametric study. A proposed design equation of shear strength of UHPC corbel was presented and checked with numerical results.

Authors: Farhan Ammar A. , Sahi Hana Abdulhussien 
Published: April 2023

The thermal performance of three solar collectors with 3, 6 mm and without perforation absorber plate was assessed experimentally. The experimental tests were implemented in Baghdad during the January and February 2017. Five values of airflow rates range between 0.01 – 0.1 m3/s were used through the test with a constant airflow rate during the test day. The variation of the following parameters air temperature difference, useful energy, absorber plate temperature, and collector efficiency was recorded every 15 minutes. The experimental data reports that the increases the number of absorber plate perforations with a small diameter is more efficient rather than increasing the hole diameter of the absorber plate with decreasing the perforation numbers. Maximum air temperature difference throughout the solar collector with 3, 6 mm perforations and without perforations are 17, 15, and 12 oC, respectively. Also, it can be concluded that the energy gained from the solar collector with 3 mm perforation absorber plate is 28.2 % more than the energy gained from solar collector without holes per day for 0.1 m3/s airflow rate. The maximum values of the thermal performance curves are 0.67, 0.64, and 0.56 for the solar collector with 3, 6 mm, and without perforations, respectively.

Published: April 2023

Purpose: To investigate the experiences of dietetic students in a faculty-supervised, noncourse-based service-learning (NSL) opportunity called Nutrition Ignition! (NI!) to understand how NSL activities contribute to dietetic education. Methods: This study used focus group methodology. A convenience sample was recruited from current members of NI!. Participants completed a brief demographic questionnaire and then engaged in a focus group discussion led by a trained moderator who followed a semi-structured guide. Six focus group discussions were transcribed, and a common theme template was developed by researchers. Results: Out of 46 eligible members of NI!, 33 agreed to participate. The main reasons participants joined NI! were to develop professional skills and to help children in the community. Participants discussed many outcomes from their participation in NI!, including enhanced communication skills, especially in terms of knowledge translation; increased ability to be flexible and adapt to “real-world” situations; deeper awareness of the research process; and expanded world view. Conclusion: This study suggests that NSL is an effective way to build dietetic students’ personal and professional skills and provide an additional opportunity in academic settings to prepare dietetic students for entry-level practice.

Published: April 2023

Purpose: MXene is two-dimensional (2D) nanomaterials that comprise transition metal carbides, nitrides, and carbonitrides. Their unique nanostructure attributes it a special role in medical applications. However, bibliometric studies have not been conducted in this field. Therefore, the aim of the present study was to conduct a bibliometric analysis to evaluate the global scientific output of MXene in biomedical research, explore the current situation of this field in the past years and predicte its research hotpots.Methods: We utilized visual analysis softwares Citespace and Bibliometrix to analyze all relevant documents published in the period of 2011–2022. The bibliometric records were obtained from the Web of Science Core Collection.Results: A total of 1,489 publications were analyzed in this study. We observed that China is the country with the largest number of publications, with Sichuan University being the institution with the highest number of publications in this field. The most publications on MXene medicine research in the past year were found primarily in journals about Chemistry/Materials/Physics. Moreover, ACS Applied Materials and Interfaces was found to be the most productive journal in this field. Co-cited references and keyword cluster analysis revealed that #antibacterial# and #photothermal therapy# are the research focus keyword and burst detection suggested that driven wearable electronics were newly-emergent research hot spots.Conclusion: Our bibliometric analysis indicates that research on MXene medical application remains an active field of study. At present, the research focus is on the application of MXene in the field of antibacterial taking advantage of its photothermal properties. In the future, wearable electronics is the research direction of MXene medical application.
Single-cell profiling of peripheral blood and muscle cells reveals inflammatory features of juvenile dermatomyositis
Authors: Chen Xiangyuan , Lian Dongsheng , Zeng Huasong 
Published: April 2023

Introduction: Juvenile dermatomyositis (JDM) is a rare yet serious childhood systemic autoimmune condition that primarily causes skin rashes and inflammatory myopathy of the proximal muscles. Although the associated immune response involves the innate and adaptive arms, a detailed analysis of the pertinent immune cells remains to be performed. This study aims to investigate the dynamic changes of cell type, cell composition and transcriptional profiles in peripheral blood and muscle tissues, and in order to clarify the involvement of immune cells in the pathogenesis of JDM and provide a theoretical reference for JDM.Methods: Single-cell RNA sequencing combined with bioinformatic analyses were used to investigate the dynamic changes in cell composition and transcriptional profiles.Results: Analysis of 45,859 cells revealed nine and seven distinct cell subsets in the peripheral blood and muscle tissues respectively. IFITM2+ and CYP4F3+ monocytes were largely produced, and CD74+ smooth muscle cells (SMCs) and CCL19+ fibroblasts were identified as inflammatory-related cell subtypes in JDM patients, exhibiting patient-specific cell population heterogeneity.The dynamic gene expression patterns presented an enhanced type I interferon response in peripheral blood monocytes and T-cells, and SMCs and fibroblasts in muscle of untreated JDM patients. EGR1 and IRF7 may play central roles in the inflammation in both CD74+ SMCs and CCL19+ fibroblasts. Moreover, inflammatory-related monocytes could regulate T-cells, and the interaction between immune cells and SMCs or fibroblasts in muscle was enhanced under the inflammatory state.Conclusions: Immune dysregulation is one of the key pathogenic factors of JDM, and type I interferon responses are significantly enhanced in peripheral blood Monos and T cells as well as SMCs and fibroblasts. EGR1 and IRF7 may play central roles in the inflammation and are considered as potential therapeutic targets for JDM.

Published: April 2023

ObjectiveTo analyze the mortality rate of patients with Klebsiella pneumoniae bacteremia (KPB) and the impact of extended spectrum beta-lactamase (ESBL) producing or carbapenem-resistance (CR) KP on the mortality rate among patients with bacteremia.MethodsEMbase, Web of Science, PubMed, and The Cochrane Library were searched up to September 18th, 2022. Two reviewers independently extracted data and evaluated risk of bias of included studies by ROBINS-I tool. A meta-regression analysis was conducted using a mixed-effects model to explore possible sources of heterogeneity. A random-effects model was used for pooled analysis in case of significant heterogeneity (I2&gt;50%). Otherwise, the fixed-effects model was performed.ResultsA total of 157 studies (37,915 enrolled patients) were included in the meta-analysis. The pooled death proportions of KPB were 17% (95% CI=0.14-0.20) at 7-day, 24% (95% CI=0.21-0.28) at 14-day, 29% (95% CI=0.26-0.31) at 30-day, 34% (95% CI=0.26-0.42) at 90-day, and 29% (95% CI=0.26-0.33) in hospital, respectively. Heterogeneity was found from the intensive care unit (ICU), hospital-acquired (HA), CRKP, and ESBL-KP in the meta-regression analysis. More than 50% of ICU, HA, CRKP, and ESBL-KP were associated with a significant higher 30-day mortality rates. The pooled mortality odds ratios (ORs) of CRKP vs. non-CRKP were 3.22 (95% CI 1.18-8.76) at 7-day, 5.66 (95% CI 4.31-7.42) at 14-day, 3.87 (95% CI 3.01-3.49) at 28- or 30-day, and 4.05 (95% CI 3.38-4.85) in hospital, respectively.ConclusionsThis meta-analysis indicated that patients with KPB in ICU, HA-KPB, CRKP, and ESBL-KP bacteremia were associated with a higher mortality rate. The high mortality rate caused by CRKP bacteremia has increased over time, challenging the public health.
