Modeling Conspicuous Collaboration for Preservice Teacher Candidates Enrolled in Higher Education Courses
Authors: Voytecki Karen S , Anderson Patricia J.
Published: June 2021

Preservice and inservice teachers in higher education should have the opportunity to observe conspicuous collaboration in action. When collaborative efforts are overt and used as teachable moments, the possibilities are clearer and the results more impactful for all participants. In this program description, the authors share benefits, challenges, structures, and implementation techniques for modeling conspicuous collaboration in higher education teacher preparation. In order to provide models of conspicuous collaboration, the authors participated in a project to co-teach aspects of general and special education teacher preparation courses at the undergraduate and graduate levels. The instructors examined their own courses, analyzing the content for each class to design class activities and assignments that could successfully be accomplished by working together and completing meaningful learning activities in multiple ways. Each faculty member delivered their assigned course, adding special collaborative learning activities and assignments that allowed students to have interactive and collaborative experiences while seeing the impact of collaboration of the instructors. Opportunities to demonstrate collaboration became apparent to the authors as students questioned repeatedly how rural K-12 teachers work to best meet the needs of their students. Preservice and inservice teachers in higher education should have the opportunity to observe conspicuous collaboration in action. When collaborative efforts are overt and used as teachable moments, the possibilities are clearer and the results more impactful for all participants. In this program description, we share benefits, challenges, structures, and implementation techniques for modeling conspicuous collaboration in higher education teacher preparation. To provide models of conspicuous collaboration, we collaborated in a project to co-teach general and special education teacher preparation courses at the undergraduate and graduate levels. We examined our own courses to design class activities and assignments that could be successfully co-taught. Each of us delivered our individual course, adding special collaborative learning activities and assignments that allowed students to experience interactive, collaborative learning while observing the purposeful collaboration of their instructors. Both of us—together with our preservice and inservice teachers—realized that optimal collaboration included clarifying roles and responsibilities, displaying respect toward the collaborative partner, holding one another accountable, setting aside time for planning and debriefing, and considering ways to combine classroom assignments and learning activities that met the requirements of both courses.

Professional Development for Secondary School Teachers and Educational Professionals in STEM Fields
Authors: Viloria Maria de Lourdes , Mireles Selina V. , Al-Tameemi Weam , Uribe Marcela
Published: June 2021

Rural communities are geographically isolated and have limited access to specialized services and ongoing support from content educational experts. As a result, rural school districts across the nation face many challenges related to the recruitment, retention, and professional development for their teachers. Studies have reported that rural school districts experience a shortage of specialized teachers and it is likely that rural school teachers will teach in content areas outside of their area of expertise. Finding mathematics and science teachers is a constant challenge. In response, we developed the Professional Development for Secondary School Teachers and Educational Professionals (PD-STEP) into STEM Fields Model, which utilizes research-based lessons aligned with curriculum standards and purposefully centered on (a) agricultural mathematics, science, and technology knowledge and skills; (b) specific needs of English language learners; and (c) indigenous, authentic agricultural topics through field-based experiences for teachers. The PD-STEP into STEM Fields Model encompasses the development of a lesson plan template and lesson topics that incorporate teachers’ professional development training on food, agriculture, natural resources, and human sciences. These professional development activities explore opportunities available in the career paths described by the United States Department of Agriculture and engender resource-rich partnerships among university faculty and rural school teachers.

Authors: Morantes Valencia Flor María
Published: June 2021

Este artículo da cuenta de una revisión conceptual realizada en torno al fenómeno del VIH – SIDA. Para ello, se desarrolló un estudio de caso en el municipio de Girardot, Cundinamarca, ya que, de acuerdo con la Secretaría de Salud de Cundinamarca en 2015, este municipio fue el segundo, después de Soacha, en registrar el mayor número de casos confirmados de portadores del virus. En línea con lo anterior, el presente análisis contiene una revisión de los casos reportados en el municipio durante los periodos 2018-1 y 2018-2. Por otra parte, el estudio cuenta además con una revisión teórica, cuyo objetivo es conceptualizar el fenómeno del VIH- SIDA desde diferentes esferas epistemológicas. Por ejemplo, explora campos como la antropología de la salud, la comunicación y la salud pública, las narrativas en salud, los itinerarios terapéuticos y las trayectorias de vida, entre otros. Finalmente, este estudio se interesa por conocer propuestas pedagógicas estratégicas, capaces de responder a las múltiples necesidades de la población portadora y reducir de esta manera la brecha social existente, no solo en el municipio de Girardot, sino en el país.
El teatro como movimiento e instrumento de acción colectiva en Colombia
Authors: Velasco Quesada Ariolfo
Published: June 2021

Los movimientos sociales en el mundo han sido una motivación significativa para el cambio y la transformación social dentro de entornos políticos, económicos, religiosos y, especialmente, de modelos gubernamentales. En ellos, interactúan manifestaciones desde diferentes ángulos, no propiamente relacionadas con las marchas; entre ellas, está la manifestación artística a través del teatro, que ha sido fundamental para la puesta en escena de las múltiples formas de desigualdad social, buscando la reflexión de cada uno de los grupos que confluyen socialmente y, por supuesto, de los actores directamente implicados. Este ensayo, a modo de reflexión, habla del papel preponderante que ha tenido el teatro como movimiento e instrumento de acción colectiva en Colombia, herramienta efectiva en la construcción de conciencia social.
El papel de Pérez Manrique dentro de la real audiencia de santa fe, y la intromisión en asuntos eclesiásticos
Authors: Barrera Soler Camilo Andrés
Published: June 2021

Este trabajo muestra el papel tan relevante que tuvieron los oidores de la Real Audiencia de Santa Fe frente a otros tipos de justicia, lo cual se hace evidente al analizar la intromisión o determinación que tuvo Pérez Manrique (1654-1662), dentro de la justicia eclesiástica; pues durante el siglo XVII fue uno de los oidores al que más cargos se formularon (por lo menos tres veces), los cuales en general se levantaban contra su persona por haber desviado o mediado dentro de una toma de justicia externa a la Real, sin embargo es sorprendente que la resolución final después de diez años lo absuelve; lo anterior nos lleva a decir que a través del estudio sobre la vida política, administrativa y social de los oidores de la Real Audiencia de Santa Fe se puede evidenciar los tipos de relaciones de poder que se daban a mediados del siglo XVII, dentro de la America colonial sobre todo en el Nuevo Reino de Granada, haciendo gran énfasis en el interés que tenía Justicia Real por controlar los estamentos religiosos, su toma de decisiones y su campo de acción.
“El zipa” persiguiendo un sueño: iniciación deportiva e identidad patrimonial
Authors: Liliana Velásquez Angelica , Gutiérrez Hernández Laura Johana
Published: June 2021

Es importante dar a conocer el valor del patrimonio cultural y generar un sentido de pertenencia en la sociedad, fortaleciendo estos aspectos desde el proceso educativo iniciado desde la primera infancia e involucrando al niño en la construcción tanto de una memoria colectiva como de significados para lograr la apropiación y participación de los estudiantes en la conservación y uso responsable del patrimonio cultural.Este artículo se realizó por medio de una investigación desarrollada en la Institución Educativa Municipal Las Villas Sede Jardín Infantil Rafael Pombo de carácter público, observando el comportamiento de los estudiantes de grado transición de esta institución, mediante lo cual se evidencia en los niños dificultades en el desarrollo de sus dimensiones (Blázquez 1999) y poco conocimiento sobre el patrimonio cultural. Es por ello que llegamos a las preguntas ¿Cómo la iniciación deportiva influye en la edad preescolar?  ¿cómo esta iniciación deportiva se complementa con el teatro y las artes dramáticas para acercarse a la integridad del proceso formativo? De donde surge la necesidad de realizar diferentes actividades enfocadas al fortalecimiento de la iniciación deportiva, además un proceso investigativo acerca de la vida y obra de Héctor el ¨Zipa¨ González quien ha sido relevante en la historia del deporte en Colombia (Revista grupo 15. 50 años del deporte en Zipaquirá. Nunca fue suplente. Página 11), que permita incentivar la identidad, el patrimonio cultural y la iniciación deportiva en los estudiantes de grado transición de la Institución.Para iniciar se llevó a cabo un diagnóstico de observación a los estudiantes con el que se tomó en cuenta la forma de comportarse y de realizar ejercicios como: circuitos, juegos cooperativos y lúdicas; posteriormente se aplicó una encuesta a cada uno de ellos acerca del personaje, cosas relevantes en cuanto al deporte y su importancia en la educación especialmente en preescolar. También se investigó sobre la vida y obra de Héctor el ¨Zipa¨ González utilizando una serie de instrumentos para obtener información con la cual se escribió una dramaturgia sobre el personaje donde se evidencian sus legados en cuanto al deporte propuesta para llevar a cabo una puesta en escena con la cual se quiere incentivar a los estudiantes de grado transición de la Institución Educativa Municipal Las Villas Sede Jardín Infantil Rafael Pombo a interesarse por la identidad y el patrimonio cultural de su ciudad.

En este trabajo damos a conocer una revisión de  la literatura en español La educación es un derecho fundamental del ser humano, pues permite su realización personal y contribuye para el desarrollo integral del país. Es uno de los deberes del Estado el garantizar su acceso, normarla y gestionar su correcta aplicación. La educación superior es sobre todo un eje de desarrollo para el Estado, porque no solo genera un crecimiento económico para el mismo, sino también un desarrollo social. Uno de los instrumentos que el gobierno ha utilizado para el impulso de la educación superior ha sido la implementación de la Ley Orgánica de Educación Superior (LOES) y los objetivos del Plan Nacional del Buen Vivir (PNBV) en este ámbito. Además, se han planteado y ejecutado algunas políticas para el desarrollo de la misma, como la creación de nuevas universidades e institutos tecnológicos, el cierre de las que no cumplían con estándares necesarios y la adecuación de las existentes. Pero cuán correctamente se han planificado y gestionado las políticas en el ámbito presupuestario, temporal, coyuntural y en cuanto al elemento humano, es lo que se quiere analizar en este trabajo. Entremezclados, confundiendo unos con otros); y que no se sigue una clasificación claramente delimitada. Finalmente, se presenta una propuesta de marco conceptual para hacer referencia a los "medios", "técnicas" e "instrumentos" de evaluación formativa y compartida en educación superior, definiendo de manera precisa la terminología asociada.

CAUSALITY BETWEEN ENERGY CONSUMPTION AND ECONOMIC GROWTH IN THE V4 COUNTRIES
Authors: Krkošková Radmila
Published: June 2021

Energy plays an important role in economic development. This paper deals with the long-run relationship between energy consumption and real GDP for V4 countries from 2005 to 2019. The analysis was based on the unit root tests, co-integration tests, and causality tests. There are two questions. The first question is if energy consumption the stimulus to GDP, resp. energy consumption causes GDP. And the second question is if GDP the stimulus for energy consumption, resp. GDP causes consumption of energy. Energy consumption has an essential role in the economy on both the demand and the supply. It means that there should be a causal relationship from energy consumption to GDP as well as vice versa. Given that in the long run the energy consumption Granger causes the GDP in Slovakia, Hungary, and the Czech Republic, it means that energy consumption could cause economic growth in these countries. The only country where no significant relationship between energy consumption and the GDP has been demonstrated in Poland.
Meteoroid Stream of Comet C/1961 T1 (Seki) and Its Relation to the December ρ-Virginids and γ-Sagittariids
Authors: Neslušan Luboš , Hajduková Mária
Published: June 2021

We answer the question of whether long-period comet C/1961 T1 (Seki) is the parent body of a meteor shower observed in Earth’s atmosphere. We model discrete parts of a meteoroid stream associated with this comet and follow the orbital evolution of its particles via a numerical integration of their orbits. The gravitational perturbations of major planets and the Poynting–Robertson effect, which influences the motion of the particles, are taken into account. We predict two showers which are related to C/1961 T1. One of these showers was identified with the December ρ-Virginids, #502. This identification confirms an earlier suggested relationship between the shower and the comet. The second predicted shower was identified with the γ-Sagittariids, #657. The radiant areas of both showers are symmetrical in respect to the apex of Earth’s heliocentric motion.
Contribution of Secondary Neutrinos from Line-of-sight Cosmic-Ray Interactions to the IceCube Diffuse Astrophysical Flux
Authors: Kochocki Alina , Takhistov Volodymyr , Kusenko Alexander , Whitehorn Nathan
Published: June 2021

In 10 years of observations, the IceCube neutrino observatory has revealed a neutrino sky in tension with previous expectations for neutrino point-source emissions. Astrophysical objects associated with hadronic processes might act as production sites for neutrinos, observed as point sources at Earth. Instead, a nearly isotropic flux of astrophysical neutrinos is observed up to PeV energies, prompting a reassessment of the assumed transport and production physics. This work applies a new physical explanation for neutrino production from populations of active galactic nuclei and starburst galaxies to three years of public IceCube point-source data. Specifically, cosmic rays produced at such sources might interact with extragalactic background light and gas along the line of sight, generating a secondary neutrino flux. This model is tested alongside a number of typical flux weighting schemes, in all cases the all-sky flux contribution being constrained to percent levels of the reported IceCube diffuse astrophysical flux.
Targeted Modeling of GW150914's Binary Black Hole Source with Dart_board
Authors: Andrews Jeff J. , Cronin Julianne , Kalogera Vicky , Berry Christopher P. L. , Zezas Andreas
Published: June 2021

We present a new method to extract statistical constraints on the progenitor properties and formation channels of individual gravitational-wave sources. Although many different models have been proposed to explain the binary black holes detected by the LIGO Scientific and Virgo Collaboration (LVC), formation through isolated binary evolution remains the best-explored channel. Under the assumption of formation through binary evolution, we use the statistical wrapper Dart_board coupled with the rapid binary evolution code COSMIC to model the progenitor of GW150914, the first gravitational-wave signal detected by the LVC. Our Bayesian method combines the likelihood generated from the gravitational-wave signal with a prior describing the population of stellar binaries and the universe’s star formation and metallicity evolution. We find that the dominant evolutionary channel for GW150914 did not involve a common-envelope phase, but instead the system most probably (≃70%–90%) formed through stable mass transfer. This result is robust against variations of various model parameters, and it is reversed only when dynamical instability in binaries becomes more likely when a strict condition favoring common envelopes is adopted. Our analysis additionally provides a quantitative description of the progenitors relevant to each channel.
Effect of H2S on the Near-infrared Spectrum of Irradiation Residue and Applications to the Kuiper Belt Object (486958) Arrokoth
Authors: Mahjoub Ahmed , Brown Michael E. , Poston Michael J. , Hodyss Robert , Ehlmann Bethany L. , Blacksberg Jordana , Choukroun Mathieu , Eiler John M. , Hand Kevin P.
Published: June 2021

On 2019 January 1, the New Horizons spacecraft flew by (486958) Arrokoth, a small body in the Kuiper Belt that is the most distant object ever visited by a spacecraft. A strong unidentified absorption band was observed in the spectrum of Arrokoth at 1.8 μm. We report here experimental evidence suggesting that the near-infrared spectrum of Arrokoth is indicative of sulfur-rich, tholin-like organic residue. The spectra of organic residues produced by irradiating ice mixtures “with H2S” CH3OH:NH3:H2S:H2O (3:3:3:1) and “without H2S” CH3OH:NH3:H2O (3:3:1) were measured to study the effect of H2S. The “with H2S” sulfur-rich laboratory-synthesized organic residue displays an absorption band at 1.8 μm that is absent in the spectrum of “without H2S” sample. This feature matches the Arrokoth spectrum better than any other expected material. This suggests the past presence of H2S ice on the surface of Arrokoth and a role for Kuiper Belt objects as a key S reservoir in the early solar system.
The Time Delay Distribution and Formation Metallicity of LIGO-Virgo’s Binary Black Holes
Authors: Fishbach Maya , Kalogera Vicky
Published: June 2021

We derive the first constraints on the time delay distribution of binary black hole (BBH) mergers using the LIGO-Virgo Gravitational-Wave Transient Catalog. Assuming that the progenitor formation rate follows the star formation rate (SFR), the data favor that 43%–100% of mergers have delay times <4.5 Gyr (90% credibility). Adopting a model for the metallicity evolution, we derive joint constraints for the metallicity-dependence of the BBH formation efficiency and the distribution of time delays between formation and merger. Short time delays are favored regardless of the assumed metallicity dependence, although the preference for short delays weakens as we consider stricter low-metallicity thresholds for BBH formation. For a p(τ) ∝ τ
−1 time delay distribution and a progenitor formation rate that follows the SFR without metallicity dependence, we find that τ
min < 2.2 Gyr, whereas considering only the low-metallicity Z < 0.3 Z
⊙ SFR, τ
min < 3.0 Gyr (90% credibility). Alternatively, if we assume long time delays, the progenitor formation rate must peak at higher redshifts than the SFR. For example, for a p(τ) ∝ τ
−1 time delay distribution with τ
min = 4 Gyr, the inferred progenitor rate peaks at z > 3.9 (90% credibility). Finally, we explore whether the inferred formation rate and time delay distribution vary with BBH mass.

Published: June 2021

The practice environment is a key element that influences the quality of psychiatric–mental health nursing care; however, little is known about it. For the current study, to explore the evidence on environmental factors influencing nursing practice in psychiatric inpatient units, a scoping review of primary research published between 2009 and 2019 was performed. PubMed, Web of Science, Scopus, and CINAHL databases were searched. Eleven articles were included. Main findings were: (a) the biomedical approach limits the development of the nursing model; (b) lack of opportunities, representation, and recognition of nurses in the organization; (c) greater support from managers for a greater perception of nurses' competence and therapeutic commitment; and (d) the need for a feeling of belonging to the team and the perception of emotional exhaustion, workload, and administrative tasks. Although psychiatric nurses have a slightly positive view of their practice environment, certain factors limit quality of care. The current review points to the need for nurses to have greater organizational support and the importance of promoting effective teamwork. Implications for mental health services include the need for support and recognition by managers, as well as the existence of a nursing model within the units. [

Overcoming Gender Stereotypes in the Process of Social Development and Getting Higher Education in Digital Environment
Authors: Abdulina Nargiz , Abisheva Aliya , Movchun Vasily , Lobuteva Alisa , Lobuteva Liudmila
Published: June 2021

Social development and higher education are among the essential tools for overcoming gender stereotypes. The changes in education associated with the digitalization of learning and work, studies show, have little changed the gender landscape. Studying the opinion of students on the problem of gender relations and stereotypes is relevant in terms of the need to determine the impact of higher education in digital environment on changes in perceptions of behavioural patterns and social roles of men and women. This study examines the impact of gender stereotypes, manifested even in online learning and communication and when working in the new digital economy on student’s choice of a life path, profession, education. The research aims to study the influence of students’ social development in the learning process on the formation of gender stereotypes among them. An anonymous written survey was the most suitable method of the study. The survey involved 350 students of socio-humanitarian, technical and natural specialities (60% − women, 40% − men). It was found that getting higher education in digital environment is crucial to social development, as this stage of life helps individuals overcome gender stereotypes. Yet, gender stereotypes continue to dominate among students anyway. To which extent do students agree that the primary purpose of a woman is the role of wife and mother? Most students (44%) agreed with this view of a woman's role, with varying degrees of confidence. Besides, approximately one in four who answered this question (24%) expressed complete agreement with this statement. On the other hand, about a quarter of respondents (26%) strongly or somewhat disagree with this statement. The results of the study can be used in international practice to overcome gender stereotypes. Social development of a person through higher education in digital environment plays a more critical role in overcoming gender stereotypes than previously thought.
The Development of an Evaluation Model to Assess the Effect of Online English Teaching Based on Fuzzy Mathematics
Authors: Zhang Yuqing
Published: June 2021

The evaluation of online English teaching effect involves multiple fuzzy factors. This paper attempts to develop a model that fully considers these factors in evaluating the effect of online English teaching. Firstly, the constraints and weaknesses of online English teaching were enumerated, revealing the key points of improving online English teaching effect. On this basis, several evaluation index systems (EIS) were established for this effect from the perspectives of teachers, students, and administrators. Moreover, an improved multi-attribute fuzzy evaluation model was created for online English teaching effect based on fuzzy mathematics. The proposed model can effectively quantify the effect of online English teaching, and enjoy a good prospect in engineering application.

Exploring Factors Influencing Mobile Learning in Higher Education – A Systematic Review
Authors: Gupta Yuvika , Khan Farheen Mujeeb , Agarwal Sonal
Published: June 2021

In order to facilitate effective learning experiences for the students, mobile learning (m-learning) has evolved as a powerful component of education – learning and teaching. M-learning, as opposed to electronic learning (e-learning) which uses small and portable devices along with laptops and desktops, uses mostly small and portable technological tools. M-learning assists in imparting knowledge focusing on the need of the learner, accessibility, infrastructure, and interaction, irrespective of the place and time. With rapid advancements in Information and Communication Technologies (ICT) and mobile devices, myriad applications (apps) and innovative m-learning and e-learning services are being developed and launched at an unprecedented pace. For students representing different demographics (age, education level, class, socioeconomic status, location, etc.) and enrolled in higher education, m-learning has quickly become the modern style and preferred format of learning and accessing knowledge for its ease of integrating different modes of learning. Motivated by this novel m-learning learning movement, this study synthesizes existing research on m-learning technologies, technological platforms that cater to both synchronous and asynchronous learning/teaching modalities for students and teachers at institutions of higher education.

L’idée que le climat des écoles primaires françaises doit être examiné avec soin au lendemain de la dernière publication des enquêtes PISA, s’impose désormais. La recherche conduite ici fait le choix de saisir la nature des relations croisées entre enseignants et directeurs. Revenant sur les suggestions récentes de l’OCDE d’améliorer le fonctionnement des écoles par une meilleure expertise des directeurs (Pont, Nusche, Moorman, Hopkins, 2008), l’auteur fait le choix d’une entrée théorique liée aux travaux récents sur le leadership et en particulier au leadership distribué (Spillane, 2008). L’analyse qualitative des questionnaires montre l’absence de tels niveaux de leadership et suggère au-delà, la faible maîtrise organisationnelle des écoles françaises comme les limites possibles de leur efficacité.
Fonctions et rôles des directeurs d’école : apports métaphoriques
Authors: Guerrier Alain
Published: June 2021

La présente recherche s’attache à dévoiler les logiques et les conceptions des directeurs d’écoles primaires françaises en matière de leadership. Amenés à spécifier par métaphores leur profession, les directeurs sont ensuite interrogés pour de plus amples explicitations. Parallèlement, la théorisation nord-américaine du leadership en éducation proposée par Spillane et al. est déconstruite selon des spécifications dynamiques propices à être confrontées aux images proposées par les directeurs. La confrontation obtenue permet le dévoilement de conceptions profondément enracinées chez les directeurs français et de prendre la mesure des écarts avec l’optimisation proposée par les chercheurs américains.
Climat social et professionnel : un comparatif écoles publiques / écoles privées
Authors: Boncompain-Katz Lucile
Published: June 2021

13,4 % des établissements scolaires en France sont privés. En nombre d’élèves, les établissements privés préélémentaires et élémentaires enregistraient, à la rentrée 2009, 892 115 enfants, soit 13,5 % des élèves d’âge primaire scolarisés de notre pays2. Les enseignants d’écoles privées passent le Concours de Recrutement de Professeurs des Ecoles mais sont aussi recrutés et formés de façon spécifique. Les valeurs prêtées à la spécificité de l’enseignement privé se traduisent-elles par un climat d’école différent de l’enseignement public ? Quelles sont les différences entre public et privé en termes de recrutement et de formation initiale des enseignants et des directeurs d’écoles ? Peuvent-elles faire varier les relations sociales au sein d’une équipe pédagogique et l’expression du leadership distribué ? Cet article tente de répondre à ces questions en s’appuyant sur les textes officiels d’une part et en les confrontant aux résultats de notre enquête menée par questionnaires d’autre part.

Sri Lanka is a proud nation in the world for its ancient architectural and irrigational structures. Unlike today, the hospitals were not served for purpose of natural labor and delivery. Most of the houses have had a private labor room (Thimbiri Geya) for the purpose. However, the architectural plan of the labor room was different from the other bedrooms of the house. The room had provided the better quality of hygienic level and health conditions to the expecting mothers and the newborn babies. The room was sometimes used for other functions including the control of epidemic diseases, control of post childbirth psychosis and for healing wounds. It is interested to understand the scientific concepts behind this labor room and then, to learn and practice them if possible, for today’s world. Therefore, experiments were carried out using three sample labor rooms (3×4 square feet sized) under the same environmental conditions to scientifically investigate the ancient architecture. Unit A were constructed similar to the ancient labor room while unit B was constructed similar to the ancient labor room, but the walls were built by cement blocks and unit C was constructed according to the modern-day room with cement floors. These three rooms were monitored for atmospheric temperature, atmospheric humidity, dissolved oxygen (DO) of water samples of well water and pipe born water and microbial actions on some selected food (bread, meat and fish). It was found out that the room temperature and humidity levels of unit A were much lower to the other rooms and the three strata of floor in unit A could be reason for those. In addition, higher DO levels and lower microbial activities were recorded in unit A. The results suggest the usage of ancient system is a way forward approach in the path of sustainability in health care facilities in the modern world. However, it is also advised to have more experiments in a longer time span to reveal more interesting features of the ancient labor room (Thimbiri Geya) in Sri Lanka.
A Forensic Anthropological Analysis on The Consumption of Forensic Science Methods Utilized to Detect Homicides Along with Sharp Weapons (With Special Reference to Court Records)

Crime is a common phenomenon in an organized society. Among the crimes, we identify as homicide is the unlawful premeditated murder of a person. Today, the criminal and the crime are meticulous. As a result, finding the culprit has become a complex issue. Undisclosed information about a crime is revealed through a criminal investigation. The methods used to uncover criminal information in criminal investigations are called forensic tactics. Methods in forensic science are used to uncover murder crimes. This research focuses on homicide crimes with sharp weapons. Accordingly, how can forensic techniques be used to examine murders committed with sharp weapons and to uncover information such as the weapon used in the murder? how the murder was committed? and the person who committed the murder? can be mentioned as the problem(s) of the research. The Monaragala High Court is the study institute used to compile the case reports related to the study. This research is a detailed study based on secondary data. Out of these case reports, from 2008 to 2016, 13 investigated murder reports were applied to accomplish the objectives. Case studies were used as a data collecting tool to detect the records. The interview method was also used partly in collecting data relevant to this study. Although many methods such as DNA technology, pollen analysis, and microscopic testing are utilized to detect homicides at an advanced level around the world, research reveals that traditional methods are still used in Sri Lanka. Accordingly, it is important to use the latest technology in Sri Lanka to bring criminals to justice and eradicate them from the criminal community.
Cultural and Religious Tourism in Majuli With Special Reference to Auniati Sattra And Uttar Kamalabari Sattra
Authors: Goswami Gitanjali , Sharma Mousumi
Published: June 2021

The paper attempts to study the potential of cultural and religious tourism industry in Majuli as a whole and Auniati Sattra and Uttar Kamalabari Sattra of the island in particular. The scope of tourism in Majuli, be it eco-tourism or religious tourism and cultural tourism is tremendous with nature’s opulence in full display here. Majuli, renowned as one of the world’s largest freshwater river island is a conglomeration of Vaishnavite religion, natural beauty, art and craft, ethnic culture and traditions which needs to be explored and showcased to the world. The Sattras (Vaishnava monasteries) and their rich heritage and cultures have given Majuli the status and pride of being the “Cultural Capital of Assam”. Today people have shifted from the traditional ways of touring in the form of going to hill stations, historical places etc. to more adventurous and unexplored destinations. Adding to the other attractions of northeast India, Majuli stands out as a jewel in the crown with its total package of natural beauty, religious monasteries, eco-tourism etc. An attempt has been made to present the uniqueness of Majuli’s Sattras, its different congregational prayer services, a distinct dance form called Sattriya and an about to be an extinct art form mask making as a potential tool to put Majuli in the tourist map of India and the world.
Prolonged Reactive Oxygen Species Production following Septic Insult

The dysregulated host response and organ damage following systemic infection that characterizes a septic event predisposes individuals to a chronic immunoparalysis state associated with severe transient lymphopenia and diminished lymphocyte function, thereby reducing long-term patient survival and quality of life. Recently, we observed lasting production of reactive oxygen species (ROS) in mice that survive sepsis. ROS production is a potent mechanism for targeting infection, but excessive ROS production can prove maladaptive by causing organ damage, impairing lymphocyte function, and promoting inflammaging, concepts paralleling sepsis-induced immunoparalysis. Notably, we observed an increased frequency of ROS-producing immature monocytes in septic hosts that was sustained for greater than 100 days postsurgery. Recent clinical trials have explored the use of vitamin C, a potent antioxidant, for treating septic patients. We observed that therapeutic vitamin C administration for sepsis limited ROS production by monocytes and reduced disease severity. Importantly, we also observed increased ROS production by immature monocytes in septic patients both at admission and ∼28 days later, suggesting a durable and conserved feature that may influence the host immune response. Thus, lasting ROS production by immature monocytes is present in septic patients, and early intervention strategies to reduce it may improve host outcomes, potentially reducing sepsis-induced immunoparalysis.
