Published: March 2023

MicroRNAs (miRNAs) are ~22nt long non-coding RNAs, which regulate the gene regulation at the post transcriptional level in both plants and animals. These miRNA are conserved in nature and hence potential base for new miRNA prediction through homology search. No miRNAs in this species are identified so far in economically important water buffalo (Bubalus bubalis). In this study, EST-based homology search, an established computational approach is used to find the potential miRNAs in buffalo. Six potential miRNA in buffalo were identified utilizing publicly available buffalo ESTs against the already known mature miRNAs of closely related species i.e. Bos taurus. Based on their sequence complementarity, target genes were identified which encode transcription factors (8%), enzymes (30%) and transporters (14%) as well as other proteins involved in physiological and metabolic processes (48%). These target genes also encode the proteins for signal transduction and normal development. This study will accelerate the way for further research on miRNAs and their functions in Bubalus bubalis.

Published: March 2023

The objective of the present study was to identify the best fit lactation model in relation to bovine leptin gene and to assess lactation persistency based on lactation curve traits in crossbred Karan Fires cattle. Incomplete gamma (Wood) function and exponential (Wilmink) function tests were used to describe the characteristics of lactation curve in first lactation. Woods model showed a comparatively better fit. Different types of lactation curves depicted by these cattle using data spread over a period of 15 years (1994 to 2009) were grouped into desired and nondesired type of lactation curve. Subsequently, genotype profiling was done using PCR-RFLP. A single nucleotide polymorphism identified in exon-2 region of bovine leptin gene, was associated with desired type of lactation curve and animals having TT genotype showed better persistency of milk yield. The results validated in test population had shown positive relationship between leptin genotypes and lactation curve traits. The inference from work has a potential application in breeding program of the country, where it may give support to existing expected producingability (EPA) based selection methodology followed for selection of dairy animals, by adding leptin genotype as one additional selection criterion for early selection in crossbred dairy bulls and cattle.

Published: March 2023

Preharvest sprouting (PHS) is one of the most important factors for lower productivity in mungbean [Vigna radiata(L.) R. Wilczek]. The morpho-physiological characters, ultra-structural variations in pods and seeds, changes andregulatory water absorption pathway of 30 mungbean genotypes in relation to pre-harvest sprouting behaviour wasstudied during kharif 2017–19 at Seed Research Technology Center, Indian Institute of Rice Research, Rajendranagar, Hyderabad, Telangana. Mungbean genotypes subjected to PHS imposed by simulated rainfall were evaluated. Rainfall simulator generates a rainfall spectrum that was similar to natural rainfall. Genotypes LGG 450 and K 851 with low score (%), while ML 267 and MGG 295 with high score (%) were screened as tolerant and susceptible to PHS. Accordingly, higher seed yield was recorded in LGG 450 (4.94 g/plant) followed by K 851 (4.20 g/plant) while lower seed yield was recorded in ML 267 (0.26 g/plant) followed by MGG 295 (0.79 g/plant). The findings were further corroborated with SEM studies by presence of sparse, wiry, short, twist or shriveled trichomes; thick cuticular pod wall, wide locular gap between seed coat (seed) and pod wall helping for the slow diffusion of moisture from endosperm to embryo. Further, the presence of lea-protein-insulated starch grains of endosperm merits lipophilic nature which might hindered dissipation of water to embryo via endosperm. The SEM studies have established ultrastructural features that determine the resistance to pre-harvest sprouting of mungbean and development of future resistant lines identification.
Assessment of sweet potato (Ipomoea batatas) accessions for growth, yield and quality traits
Authors: PAVITHRA P , THANGAMANI C , PUGALENDHI L , KUMAR J SURESH
Published: March 2023

From the study it was noticed that winter sweet potato crop (first season) recorded higher tuber yield due to more utilization of photosynthates, and optimum temperatures for tuberisation and tuber bulking. Second season crop (summer to early monsoon crop) recorded higher vegetative growth which was due to more sunlight and higher temperatures during the crop period which promoted vegetative growth. The pooled analysis of two season’s data revealed that genotype Ib 73 recorded higher tuber length, number of tubers per vine, single tuber weight, tuber yield/vine and marketable tuber yield per hectare, maximum dry matter content, which had a positive correlation with tuber yield. Less weevil infestation percentage was recorded in Ib 73, it might be due to the characteristic feature of thin vine with more latex content. One of the important quality parameters is β-Carotene content in the tuber, which was recorded maximum in the variety Sree Kanaka, thus it may be recommended for the alleviation of malnutrition in children. However, Ib 73 excelled other genotypes in terms of yield and cooking quality characters with low TSS and total sugar content, hence it can be recommended for commercial cultivation among the farmers by replacing potatoes for culinary purpose.
Students’ explanations of a complex natural phenomenon using mathematical modeling as a design feature in a model-based inquiry unit
Authors: Auning Claus , Auning Mette
Published: March 2023

This research investigates the ways in which mathematical modelling as a design feature support or constrain students’ understandings and explanations of a complex natural phenomenon and how students experience the relevance of mathematical modelling in a model-based inquiry (MBI) unit. To support lower secondary students in using mathematical modelling, we developed an MBI unit based on a complex natural phenomenon, a cloudburst event, in which mathematical modelling was essential to understanding and explaining the phenomenon. The research took place in two Danish schools and the unit comprised 12 lessons over a period of one week. The sample group consisted of 40 students in the 14–16 years age group. For the analysis of the students’ mathematical modelling, the research used an adaptation of the modelling cycle proposed by Blum and Leiß (2005) to interpret the students’ artefacts. A subset of participants (n = 7) was also interviewed about their models to gain insights into how students experience the relevance of mathematical modelling in the MBI unit. Results show that the majority of the students – 37 out of 40 – were able to understand the mathematical problem from the anchoring phenomenon and model the phenomenon from a mathematical perspective, but we also see that a small number of students have problems in completing all the facets of the mathematical modelling cycle and are not able to validate the solution of the mathematical problem in relation to the anchoring phenomenon. Students expressed that their own modelling process along with the mathematical modelling helped them better understand the various elements of the anchoring phenomenon.

Authors: Simon Cleonice , Bavaresco Paulo Ricardo
Published: March 2023

The article aims to present the type of education offered to peasants, with emphasis on the conditions of rural teachers who seek to offer an education designed to value the subject, as agents capable of contributing to the transformation of society. Therefore, from the problematization of the dichotomy between urban and rural schools, the main movements already developed in favor of the rights of the peasant population will be mentioned, as is the case of the creation of the LDBEN (Law of Guidelines and Bases of National Education) and the MST (Landless Movement). This is an applied research, with a quantitative and qualitative approach and an exploratory purpose, designed based on two electronic questionnaires that, due to the Covid-19 pandemic and social isolation, were applied through the email of students and teachers from two schools in the interior of the municipality of Anchieta/SC. Data collection took place between February and May 2020 and the analysis was performed using the Bardin methodology. Ten professors and forty-nine students participated in the research. The results showed that, despite the existence of difficulties related to the lack of teacher training to meet the real needs of students in rural areas, there is an awareness on the part of the participants regarding the need for public policies that encourage continuing education courses as a means of to guarantee a better professional qualification, as well as to develop a teaching methodology capable of encouraging the population to remain in the countryside.

Published: March 2023

The aim of this study is to illustrate and discuss the fundamentals of a well-succeeded and minimally invasive technique of surgical reintervention for installing implant in the reduced area of the alveolus, affected by agenesis, and traumatized by an unsuccessful intervention. Materials and methods: A 27-year-old patient sought dental care and her main cause was the great dissatisfaction with the aesthetic sequelae in the region of the right upper lateral incisor, in addition to the uncertainty regarding the predictability of a new unitary implant. Imaging exams showed trauma in the middle and apical region of the canine root surface. The dimensions of the edentulous area varied between 4.6 and 5.52 mm. A small diameter implant (BLT 2.9mm SC, Loxim SLActive® 12 mm, TiZr - Straumann Dental Implant System) was planned and installed, in addition to a subepithelial connective graft. Results: The results achieved allowed to restore the desired function and aesthetics, with excellence, low morbidity, in addition to a predictability favored by the benefits related to small diameter implants. Conclusions: The concept of minimally invasive dentistry is becoming an effective surgical approach and, although these implants present a higher risk for fracture than do large-diameter implants, implant fractures are rarely observed.
Appreciation of the ecstasy of Santa Teresa
Authors: Santos Paula Isabel Gonçalves dos , Coelho Marta Silva , Bastos Carla Patrícia Gonçalves
Published: March 2023

The Ecstasy of Santa Teresa or the Transverberation of Santa Teresa concerns a sculpture by Gian Lorenzo Bernini, which represents the mystical experience of Saint Teresa of Ávila pierced by an arrow of divine love wielded by an angel, assuming itself as one of the greatest masterpieces of the baroque style. This review aims to explore and synthesize the work of Éxtase de Santa Teresa and, at the same time, present a reflection from a clinical point of view, through a framework with the field of psychoanalysis. A bibliographic search was carried out to be able to reflect and, above all, raise questions, in a work as rich in symbolism as it is in beauty.
Characterization of explosive performance parameters: ANFO and explosive emulsion
Authors: Vieira Fabrício Thiengo , Braga Júlio D’Auria
Published: March 2023

The most commonly used explosives, for civil purposes, in construction and mining are Ammonium Nitrate Fuel Oil (ANFO) and explosive emulsions. Both are ammonium nitrate-based and detonate under the same chemical reaction between nitrate and mineral oil, given that the ANFO is composed of tiny grains of porous nitrate with diffused oil, and the emulsion is in the form of a liquid, continuous, viscous phase oily and the discontinuous aqueous phase. The study of parameters that measure explosive performance is fundamental to understanding the behavior of the explosion. Important parameters are the speed and pressure of detonation, the heat of the blast (energy), and the volume of gas produced. These properties help judge whether a particular explosive is convenient or not for the situation in question because, in some applications, high speed is required to increase the capacity of fragmentation, for example, when you want to fragment hard rocks. However, there is no need to fragment in some moments but to displace. Other properties, such as gas volume, become more relevant in such cases.

Authors: Martinez-Perez M. , Sarmiento-Franco Luis Armando , Sandoval-Castro C.A. , Santos-Ricalde R.H. , Safwat A.M. , Garcia-Hernandez Y.
Published: March 2023

Background. Rustic birds such as Rhode Island Red are adapted to the tropical environmental conditions. Raising them using free range in the tropics improve meat quality. However, the production cost is high when males are used for meat production, due to their low feed efficiency. Objective. To assess growth performance of Rhode Island Red male chickens as affected by indoor vs. outdoor housing systems between 7 to 14 weeks of age. Methodology. One hundred and twenty male chickens were allotted in two different housing systems: indoors vs. outdoor with acces to a free-range pasture of native plants. The experimental diet in growing stage (7-14 weeks of age) included processed Mucuna pruriens (soaked and cooked) in 15 % of the diet. For data analysis, a generilized linear model was used with repeated measures at different ages, considering effects of treatment, week and the interaction between both. The study of the whole experimental period considered the fixed effect of trial and liveweight at the start of the test as covariable. Results. Week was the most consistent effect, and treatment only affected feed intake, with values of 91.99 vs. 87.54 g/bird/day in indoor vs outdoor, respectively. There was only interaction between treatment and week in weight gain. For the whole period, there were no differences due to the housing systems for the variables under study. Nevertheless, initial live weight affected weight gain and conversion. Implication. Alternative raising systems for rustic birds in the tropics can be an option for small and middle producers, where animal welfare and feed costs improve. Conclusion. The productive behavior in Rhode Island Red male chickens is not modified by the raising system.             
VALORACIÓN ECONÓMICA AMBIENTAL: LA TENDENCIA DE LA INVESTIGACIÓN EN MÉXICO Y LATINOAMÉRICA
Authors: Gutiérrez-Castro Adriana Isabel , Flores-Domínguez Ángel David
Published: March 2023

Background. The results of the economic valuation of ecosystems facilitate their management and conservation, although they frequently focus on the economic valuation of the resource per se, and the willingness to pay for its touristic use, frequently leaving aside the valuation from the perspective of the inhabitants who live in the area of influence of the ecosystems or who closely depend on them. Objective. To analize the trend that economic valuation studies have followed in Latin America, during the period between 2011 and 2022, is analyzed with the aim of determining the type of interest that motivates researchers, that is, to identify the value assigned by the visitor and the value that the settler asigns. Methodology. Publications on economic valuation studies were analyzed, with emphasis on the Contingent Valuation Method in Latin America, related to tourism (ecotourism and nature tourism) and the use of natural resources. The search was performed in open access databases. The publications were classified by type, subject and country of origin. Peer reviewed documents, thesis and final reports of projects consistent with the theme were considered. Main finding. The results obtained, revealed that the trend of research in Latin America in this last decade, in terms of economic valuation of ecosystems, has been mainly directed towards visitors to determine the value that they assign to the ecosystem based on their preferences and travel satisfaction, in terms of Willingness to Pay, according to the Contingent Valuation Method. In the case of the economic valuation works under the aforementioned method, but aimed at knowing the value that the ecosystems have for the inhabitants, it was observed that the variables that are most related to the Willingness to Accept Compensation are the level of studies and the income/occupation. Implications. Inevitably, economic valuation studies must include social, cultural and environmental aspects under which the communities that depend on the ecosystem are governed, because evaluating only quantitative variables could underestimate the real value, since they are not developed under the consideration of the social context that makes visible the effort to pay or accept compensation. Conclusion. It is necessary to include methodological approaches that comprehensively evaluate the resources by including intangible values (culture, history, uses and customs), in an inclusive strategy effort, which allows the original communities to maintain their identity and, at the same time, to be competitive in the nature tourism market, without losing sight of the conservation of the appropriate ecosystems.
The Individuals with Disabilities Education Act (IDEA) and the Equity Imperative: Examining Early Childhood Transitions to Special Education
Authors: VOULGARIDES CATHERINE K. , BARRIO BRENDA L.
Published: March 2023

Equity issues continue to surround the supports and services provided to students with dis/abilities from birth onward, especially for children of color and despite extensive legal protections guaranteed through the Individuals with Disabilities Education Act (IDEA). The purpose of this article is to examine how these systemic issues unfold in practice during early childhood transitions as young children of color with dis/abilities move from preschool to an elementary school setting. Using ethnographic data gathered from a large suburban school district in the northeastern United States, we explore the equity implications associated with the transition from preschool to kindergarten in a sociodemographically diverse school district. We used a context-centered approach to examine how educators use IDEA to serve families during the transition process and how educators and families interact with each other during transition planning meetings. Cultural misunderstandings and power differentials between caregivers and educators emerged from the data analysis and provided insight into how and why IDEA procedural protections were insufficient for assuring the rights of students with dis/abilities were protected during the transition process. We argue that the extensive procedural protections for children served under IDEA are inadequate in assuring equity in special education outcomes during the transition process. We conclude that the transition process does not disrupt oppressive practices, effectively thwarting equity and access in early childhood education. We end with recommendations for improving the process.
Beyond Brown: Empirical Research on Diverse Learners with or At-Risk for Specific Learning Disabilities From 1994–2012

Published: March 2023

We conducted a literature review to determine the presence of culturally and linguistically diverse (CLD) learners in research on specific learning disabilities (SLD) from 1994–2012. We believed that disaggregation of results by category might identify nuances that will guide future policies, research, and practice. We deemed it logical to begin with SLD because it is the largest population of students in the high-incidence categories. Our search yielded 52 articles for review. Results indicated primary foci on assessment, instructional and behavioral interventions, academic achievement, and disproportionality. In addition, we found that very little research has addressed contextual factors, beyond student characteristics, that affect or predict achievement. Implications for future research are provided within the context of the Brown decision.
Pursuing Inclusive Schools: The Case of Youth Researchers of Color Expanding a New Vision
Authors: GONZÁLEZ TAUCIA , BERTRAND MELANIE , SALINAS SARAH
Published: March 2023

This qualitative study examines how youth of Color with and without disabilities used youth participatory action research (YPAR) to advance a youth-centered conceptualization of inclusive education (IE). We examined data over the course of an academic year, which included weekly video recordings of whole-group and small-group interactions in the YPAR meetings, participant artifacts, youth and school adult interviews, and weekly adult researcher reflections. Using an interdisciplinary theoretical framework, we used inductive and deductive ethnographic approaches to code and categorize data. Findings indicate that both YPAR youth and school personnel contended with a lack of resources, but only youth identified relational tensions with their teachers. YPAR youth re-envisioned an action-oriented school with new teacher–student relationships, whereas school personnel wanted student voice but for academic rather than emancipatory outcomes. A youth research presentation functioned as a critical tool for personnel to re-envision equity through a youth-centered vision. The findings make the case for a participatory era of IE that centers the experiences of historically marginalized youth.
Perceptions of African American and European American Teachers on the Education of African American Boys
Authors: Bacon Ellen , Banks Joy , Young Kathryn , Jackson Francesina
Published: March 2023

The authors interviewed 27 teachers (16 African American and 11 European American) on instructional factors contributing to overidentification of behavior problems in African American boys. Interviews focused on teachers' perspectives of effective teachers, teacherstudent relationships, and communication styles. Analysis of the interviews showed that both African American and European American teachers believed in the importance and positive impact of having caring relationships with students. However, African American teachers placed a higher value on being personally involved with students, providing protective guidance, and knowing the students' family and community. European American teachers valued teachers who provide good academic instruction, have consistent expectations and consequences, and are involved in students' school activities. Both groups believed there were important differences in communication styles between some African American women teachers and European American teachers in managing classrooms and disciplining students.
Challenges and Instructional Approaches Impacting the Literacy Performance of English Language Learners
Authors: Markham Paul , Gordon Karen
Published: March 2023

For English Language Learners (ELLs), the process of becoming literate in English is daunting. Not only are these students faced with the same literacy challenges faced by native English-speaking students, but they are also challenged with extensive diversity issues relating to substantial differences in linguistic, cultural, and academic background experiences. This paper reviews the challenges faced by ELLs in learning to read in English. Subsequently the paper discusses the major instructional approaches designed to improve the literacy skill levels of these individuals.
Preparing Highly Qualified Teachers for English Language Learners With Disabilities and at Risk of Disabilities
Authors: Kushner Millicent
Published: March 2023

The No Child Left Behind Act's emphasis on universal standards of academic performance, defined as proficiency in grade-level core curriculum and state academic assessments, challenges general education program personnel to higher standards of professional practice. Because schools must report student achievement by subgroups, including students with disabilities and English language learners (ELLs), reform efforts have increasingly focused on closing the achievement gap between these subgroups and mainstream peers. However, little information is available about the qualifications of teachers who serve ELLs who also have disabilities. This article delineates critical teacher competencies to address the needs of these students and of ELLs who are at risk for special education placement.
General Educators' Perceptions and Attributions About Asian American Students: Implications for Special Education Referral
Authors: Hui-Michael Ying , García Shernaz
Published: March 2023

This qualitative study investigated five elementary classroom teachers' perceptions of, and attributions about the school performance of Asian American students. Using naturalistic inquiry, data were obtained through interviews, classroom observations, document reviews and field notes; and were analyzed using grounded theory techniques. The findings revealed that positive, stereotypical perceptions about Asian culture generally influenced teachers'attributions about the success or failure of their Asian American students. Specifically,they were likely to overlook low performing, struggling Asian American students unless they demonstrated challenging behaviors. Further, teacher attributions reflected limited understanding of culture, second language acquisition, and disability; students' limited English proficiency was viewed as the overriding contributor to low performance of English language learners. Implications for professional development and future research are discussed.
Culturally and Linguistically Diverse Parents’ Perceptions of the IEP Process
Authors: WOLFE KATIE , DURÁN LILLIAN K.
Published: March 2023

Many parents of students with disabilities face barriers to meaningful participation in Individualized Education Plan (IEP) meetings; parents who are culturally and linguistically diverse (CLD) encounter additional challenges. Given the changing demographics of the United States and the central role of the IEP in special education, it is important for educators to be aware of and responsive to the experiences of parents who are CLD. This literature review examines nine recent studies investigating CLD parents’ perceptions of their role in the IEP process. Common themes include language barriers, cultural barriers, and insufficient information. Recommendations for improving the experiences of parents who are CLD focus on increasing the availability of qualified interpreters and supporting educators to engage in culturally and linguistically responsive practices.
Resistance Theories: Exploring The Politics of Oppositional Behavior
Authors: Danforth Scot
Published: March 2023

Special educators have historically used psychological theories to explain students? disruptive and oppositional behavior. Sociological research and theories have played a secondary or even nonexistent role. The sociology of education tradition within general education has developed an extensive literature examining student misbehavior. This article presents the resistance theories, one strain of the critical sociology of education. Given the preponderance of students of lower social class and minority group status within special education, these theories offer insightful and useful ways for special educators to understand the political nature of oppositional behavior. These theories provide suitable ways of interpreting the underlying political tensions that reside behind behavior and guidance for teachers who want to develop the school as a community enacting the social ethics of democracy.
No Easywalk: African-American Educators Coping With Their Own Children With Special Needs
Authors: Lue Martha , Green Cheryl
Published: March 2023

In parenting a child with a disability, you face a major choice. You can believe that your child's condition is a deathblow to everything you've dreamed and worked toward until now, or you can decide that you will continue to lead this life you'd planned—and incorporate your child into it. Parents who choose the latter course find they do a tremendous amount of growing. They find inner strength they didn't know they had. (Simons, 1987, foreword)
Embracing and Building Culturally Responsive Practices
Authors: Kozleski Elizabeth , Sobel Donna , Taylor Sheryl
Published: March 2023

Individual teacher excellence can only become collective tradition when the contexts in which teachers practice and learn are able to support, sustain, and expect culturally competent practice. Culturally responsive systems require the development of individual and collective discourse and practice focused on exploring how cultural perspectives, experiences, and histories shape and divide members of the system. This article provides an approach to building culturally responsive practices that focuses on practitioners' understandings about their own roles in renewing and reforming school and classroom cultures and practices. The authors examine current trends in professional development for culturally responsive practices and suggest a systems model for creating the discourse between practitioners necessary for improving culturally responsive practices.
An Organizational Analysis of the Overrepresentation of Poor and Minority Students in Special Education1
Authors: Skrtic Thomas
Published: March 2023

By considering the overrepresentation problem in special education from an organizational perspective, the author argues that it is part of a broader problem associated with the political function of special education within public education. From this perspective, special education is an unintended consequence of bureaucratic schooling, an institutional artifact that protects the legitimacy of nonadaptable organizations faced with the changing values and expectations of an increasingly diverse democratic society. The author proposes an alternative organizational structure for schools that resolves the overrepresentation problem, advances the spirit of the Individuals with Disabilities Education Act and inclusive education, and turns educational equity into a precondition for educational excellence in schools and, ultimately, for economic and political excellence and equity in society.
Voices of Tribal Parents and Caregivers of Children with Special Needs
Authors: Banks Susanrae
Published: March 2023

Educational reform presents a number of challenges for elders, tribal educational leaders, American Indian and Alaska Native (AI/AN) teachers and administrators, and families across the United States, including the pressing need to address parent or caregiver and community involvement in education. This study was conducted to (a) summarize major factors that impact special education service delivery for AI/AN children and young adults, (b) highlight legal and ethical issues by sharing six AI/AN parents' and caregivers' personal stories, and (c) discuss the implications of the issues raised for service delivery, policy development, and research. Qualitative methods were chosen to obtain an in-depth knowledge of individual participants' experiences, thoughts, and recommendations regarding serving AI/AN children with disabilities. Ethnographic interviews were conducted and several themes emerged from the data including AI/AN parents' and caregivers' responses regarding professional development, information sharing, assessments, individualized education program and individual family service plan implementation, and cultural concerns. The implications of shared individual issues within each theme are discussed.

De los 131 casos analizados, 11 fueron perdidos de seguimiento (6%); de los restantes 120, 26 se hallaban fallecidos al final del estudio (21.7%). Se analizaron las siguientes variables: edad, sexo, síntomas de miastenia gravis al momento del diagnóstico, estadificación de Masaoka (1994) del tumor original, clasificación histológica de la OMS (1999), radioterapia postoperatoria y evolución clínica de la miastenia gravis según la clasificación modificada de Osserman. Fueron analizados 66 hombres (54%) y 56 mujeres (46%), con una mediana de edad de 48 años (rango 13-78); 78 presentaban miastenia gravis al momento del diagnóstico (64%), y el 97% de ellos persistían sintomáticos luego del tratamiento quirúrgico. En el análisis univariado, la presencia de miastenia gravis al momento del diagnóstico (HR 0.527, IC 95% 0.243 - 1.141, p = 0.10), la evolución clínica de la enfermedad (HR 18.81, IC 95% 4.070 - 86.886, p = 0.000) y el estadio de Masaoka (HR 2.044, IC 95% 0.934 - 4.474, p = 0.074) se asociaron significativamente con la frecuencia de la muerte en pacientes con timoma. En el análisis multivariado, ese valor resultó ser casi 7 veces mayor en timomas invasores que en los estadios I y II (HR 7.272, IC 95% 2.19 - 24.11, p = 0.001), mientras que la radioterapia adyuvante disminuyó en un 79% este riesgo en nuestra población (HR 0.214 IC 95% 0.0648 - 0.7085, p = 0.12). Los timomas con estadios tempranos de Masaoka y el tratamiento postoperatorio adyuvante en lesiones avanzadas son factores independientes de buen pronóstico.
The taxonomic separateness of the species Aporophyla lueneburgensis (Freyer, 1848) and Aporophyla lutulenta ([Denis & Schiffermüller], 1775) occurring in Poland (Lepidoptera: Noctuidae)
Authors: Nowacki Janusz , Mahecha-J. Oscar , Wasala Roman , Zubek Anna
Published: March 2023

Morphological and genetic comparisons were carried out of specimens of two sister species Aporophyla lueneburgensis (Freyer, 1848) and Aporophyla lutulenta ([Denis & Schiffermüller], 1775), which are distributed allopatrically in Poland. The specimens from different populations of these two species hardly differ morphologically but do differ genetically. The mean genetic distance between the groups of A. lueneburgensis and A. lutulenta examined here indicates that their geographic populations can be treated as belonging to separate species. Hence, A. lueneburgensis and A. lutulenta occurring in Poland can be regarded as two separate but sister species.

لم يأت التطور العلمي التكنولوجي الذي شهده العالم اليوم من فراغ بل نجم عنه العديد من المشاكل القانونية، لذلك كان من الطبيعي أن تصبح قضية حماية المتضررين من نتائج هذه الأخطار من أهم المشاكل التي تبحث عن الحلول، ولاسيما أنها تهدد كيان المجتمع حيث ان أغلب الدول اتجهت صوب إنشاء قاعدة معلومات الكترونية وذلك لخدمة غرض معين أو قد تُستخدم لموضوع محدد فلم تعد المعلومات والبيانات والملفات مخزونة بصورة ورقية فحسب، بل ان تكنولوجيا المعلومات والاتصالات أخذت دورها في الحياة العامة والخاصة على حد السواء حيث بات العصر يتحرك من خلالها، فقد اسهمت بتسهيل التعاملات الشخصية والمالية وأصبحت متوغلة في جميع مجالات الحياة الانسانية، وباتت العلاقة طرديه بين تكنولوجيا المعلومات  وامن الدول، حيث ازدادت الهجمات الإلكترونية وشهدت تطور ملحوظ بسبب التحول الرقمي المتنامي، وبذلك تعرضت المصالح الالكترونية الى عدة أخطار مجهولة نجم عنها اضرار عديدة، وحيال كل هذه المخاطر التي تحاصر الانسان كان لابد من البحث عن وسائل تساعده على تحمل آثار هذه الأخطار في حالة وقوعها؛ وتضمن الحماية الفعالة لمستخدمي الفضاء الالكتروني، ولاسيما أن مبدأ المسؤولية أصبح عاجزاً عن ضمان الحماية الفعالة، وتلافياً لهذا العجز ظهرت الحاجة إلى نظام تكميلي لمبدأ المسؤولية يقف جنباً إلى جنب معه، وقد يتم ذلك من خلال تطوير وسائل الضمان المالي والمتمثلة بفكرة التأمين عن الاضرار الالكترونية، ولاسيما وأن تعويض الأضرار الالكترونية الناجمة عن هذا الخطر تتسم بكونها عالية الكلفة قد يتعذر بأحيان كثيرة على محدث الضرر تغطيتها

OBJECTIVES: To describe the burden of COVID-19 in Swiss long-term care facilities in 2020, to identify its influencing factors, and to assess vaccination rates among residents and healthcare workers at the end of the vaccine campaign in Switzerland in May 2021.

DESIGN: Cross-sectional survey.

SETTING AND PARTICIPANTS: Long-term care facilities from two Swiss cantons (St. Gallen / Eastern Switzerland and Vaud / Western Switzerland).

METHODS: We collected numbers of COVID-19 cases and related deaths and all-cause mortality for 2020, potential risk factors at the institutional level (e.g. size, infection prevention and control measures, and resident characteristics), and vaccination rates among residents and healthcare workers. Univariate and multivariate analyses were used to identify factors associated with resident mortality in 2020.

RESULTS: We enrolled 59 long-term care facilities with a median of 46 (interquartile range [IQR]: 33–69) occupied beds. In 2020, the median COVID-19 incidence was 40.2 (IQR: 0–108.6) per 100 occupied beds, with higher rates in VD (49.9%) than in SG (32.5%; p = 0.037). Overall, 22.7% of COVID-19 cases died, of which 24.8% were COVID-19-related deaths. In the univariate analysis, higher resident mortality was associated with COVID-19 rates among residents (p < 0.001) and healthcare workers (p = 0.002) and age (p = 0.013). Lower resident mortality was associated with the proportion of single rooms (p = 0.012), isolation of residents with COVID-19 in single rooms (p = 0.003), symptom screening of healthcare workers (p = 0.031), limiting the number of visits per day (p = 0.004), and pre-scheduling visits (p = 0.037). In the multivariate analysis, higher resident mortality was only associated with age (p = 0.03) and the COVID-19 rate among residents (p = 0.013). Among 2936 residents, 2042 (69.9%) received ≥1 dose of the COVID-19 vaccine before 31 May 2021. Vaccine uptake among healthcare workers was 33.8%.

CONCLUSION AND IMPLICATIONS: COVID-19 burden was high but also highly variable in Swiss long-term care facilities. severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among healthcare workers was a modifiable factor associated with increased resident mortality. Symptom screening of healthcare workers appeared to be an effective preventive strategy and should be included in routine infection prevention and control measures. Promoting COVID-19 vaccine uptake among healthcare workers should be a priority in Swiss long-term care facilities.
Assessment of the Deadweight Loss Arising from the Imperfect Competition in the Banking Market

Financial market failures lead to deadweight (welfare) loss for society. Assessment of the deadweight loss started with the so-called Harberger Triangles, where Harberger offered a clear and persuasive derivation of the triangle method of analysing the deadweight loss and applied the method to estimate deadweight losses due to income taxes in the United States. Hertog further put the deadweight loss into the model with government intervention to assess the optimal level of welfare loss control. This concept is central to regulatory economics. Harberger’s approach is based on the deviation of market equilibrium measured in terms of price and quantity. When analysing imperfect competition as one of the market failures, authors have identified in the literature variables for “price” and “quantity”. The research presents the approach how calculating the deadweight loss arising from the imperfect competition using the following variables: “price” – interest rates (loans), “quantity” – exposure of loans on banks’ balance sheets. The outcome of the research is integral for the assessment of the deadweight loss arising from imperfect competition. Deadweight loss calculations for selected countries show results corresponding to the expectation to be lower than 12% - the maximum value is 4,6% for Latvia, which experienced the most significant increase in the banking market concentration from the sample. Research methods used: literature analysis, regression analysis, and mathematical analysis tools (integrals).

An excellent quality of public services is a way to improve the public satisfaction index. The public will be satisfied if the performance of public services tends to be higher than community expectations. Multi-ethnic Indonesia has different perceptions about the quality of public service. Thus, in this case, this study aims to see the effect of service quality on public satisfaction through the role of public managers in the tourism sector of various ethnic groups in Sumatra, Indonesia. This research is an associative quantitative study conducted on people of multiple ethnicities. Determination of the sample using the Cluster Random Sampling technique and continued with convenience sampling. The sample of this research is 1,499 respondents. The Likert scale questionnaire, previously tested for reliability and validity regarding content and empirical test items, was used for data collection in the field. The collected data was then analysed using Structural Equation Modeling (SEM) Analysis Moment of Structural (AMOS) statistics and continued with the Sobel test. The literature study also supports data collection. The study’s results prove a significant direct effect between service quality variables and the role of public managers on satisfaction. Moreover, this analysis found that service quality variables indirectly impact satisfaction through the manager’s role. Thus, the research results provided evidence that the research model can be utilised as an academic reason to strengthen the theories and models that have been reviewed in this research study.

Microglia, similar to peripheral macrophages, are the primary immune cells of the central nervous system (CNS). Microglia exist in the resting state in the healthy CNS, but can be activated and polarized into either M1 or M2 subtypes for immune defense and the maintenance of CNS homeostasis by multiple stimuli. Several long noncoding RNAs (lncRNAs) mediate human inflammatory diseases and neuropathologies by regulating their target genes. However, the function of common lncRNAs that contribute to microglial activation remains unclear. Thus, we used bioinformatic approaches to identify common lncRNAs involved in microglial activation in vitro. Our study identified several lncRNAs as common regulators of microglial activation. We identified 283 common mRNAs and 53 common lncRNAs during mouse M1 microglial activation processes, whereas 26 common mRNAs and five common lncRNAs were identified during mouse M2 microglial activation processes. A total of 648 common mRNAs and 274 common lncRNAs were identified during the activation of human M1 microglia. In addition, we identified 1,920 common co-expressed pairs in mouse M1 activation processes and 25 common co-expressed pairs in mouse M2 activation processes. Our study provides a comprehensive understanding of common lncRNA expression profiles in microglial activation processes in vitro. The list of common lncRNAs identified in this study provides novel evidence and clues regarding the molecular mechanisms underlying microglial activation.
