Published: March 2023

A cidade de Abaetetuba-Pará teve expansão urbana iniciada a partir das margens do Rio Maratauíra, o que provocou sua descaracterização e resultou no que se denomina como Planície Tecnogênica. Essa paisagem é marcada por eventos de inundação e colapsos do solo, refletindo os riscos ambientais existentes. Este artigo visa subsidiar o planejamento urbano e a gestão ambiental, com destaque para as áreas de risco, onde estão os bairros do Algodoal, São José e Centro. Para isso, o presente estudo realizou levantamento bibliográfico, consultas à legislação urbana e ambiental, pesquisa documental, trabalhos de campo e elaboração de mapa de risco. Assim, considerando esta realidade, foram propostos instrumentos referentes ao ordenamento territorial como a identificação de Preservação Permanente (APP), a criação de Zonas Especiais de Interesse Social (ZEIS) e intervenções nas áreas que apresentam ameaças ambientais.Palavras-chave: Planejamento Urbano.

O aumento da informalidade urbana em diversas cidades brasileiras à implementação de programas públicos de regularização fundiária para melhorar a qualidade de vida da população. Para a compreensão deste cenário é importante entender os efeitos históricos de alguns programas que priorizaram a propriedade privada e levaram à intensificação de fluxos migratórios, mercantilização da terra e exclusão socioespacial, principalmente na Amazônia. Este trabalho tem por escopo estudar o processo histórico de constituição da estrutura fundiária na Amazônia até a formulação do Programa Terra Legal. Trata-se de pesquisa qualitativa, que se utilizou de pesquisa bibliográfica, documental e coleta de dados secundários pertinentes ao assunto. Como resultado principal, constatou-se que o Programa Terra Legal possui efeitos limitados rumo à democratização do acesso ao solo, permitindo a mesma trajetória de exclusão social.Palavras-chave: Amazônia Legal.

Aportes al estudio de la alimentación prehispánica y los cultivos andinos en el sector centro-sur de la Quebrada de Humahuaca (Argentina)
Authors: Scaro Agustina , Musaubach Maria Gabriela
Published: March 2023

La alimentación es una actividad estructurante y organizadora de la vida social, en la cual dar y recibir alimentos se convierte en el símbolo de la relación dentro del grupo. En esta oportunidad, se analiza el procesamiento culinario y su consumo en el sector centro-sur de la Quebrada de Humahuaca (norte de Argentina) bajo el dominio incaico (ca. 1430/80-1536 d. C.), en el que se busca identificar los cultivos andinos procesados y consumidos a partir del estudio arqueológico de los microrrestos vegetales. Se realizaron estudios arqueobotánicos de fitolitos y granos de almidón entrampados en el tártaro dental de dos individuos inhumados en las Tumbas 1 y 2 del sitio Esquina de Huajra. Se identificaron fibras vegetales, granos de almidón y fitolitos de cultivos andinos (poroto y maíz). En el caso de los granos de almidón modificados, se pudo describir daños producidos por calor en seco y en húmedo (i.e. tostado, hervido). A estos estudios se sumó el análisis morfofuncional del equipamiento culinario (vasijas cerámicas) hallado en el asentamiento con el fin de avanzar en hipótesis acerca de los modos de preparación/cocción de los cultivos identificados.

Published: March 2023

This study aimed to determine the effects of project-based learning in the Covid-19 pandemic era on biology students' metacognitive and critical thinking skills in the genetics concept. The research model used was a quasi-experimental design. The population in this study were fifth semester students who offered genetics courses consisting of 4 classes A to D. Samples were taken randomly, that is classes A and B. The data were analyzed using the Anacova. The results show that students with the PjBL model have better metacognitive skills and thinking skills than those with conventional learning models. The PjBL model could be used as a reference to improve the metacognitive and critical thinking skills. Therefore, further research can be used to examine PjBL learning models on other higher thinking skills such as collaboration skills, problem-solving skills, and creative thinking skills.

Published: March 2023

This research was carried out with the main objective of developing tools that can help the learning process of students in statistics courses who have had difficulty improving their learning outcomes because of the lack of learning materials prepared by lecturers for them to be used as the main reference while programming the course. Departing from the in-depth needs analysis carried out and the research method used, namely research and development, the researcher then designs a prototype of teaching materials that will be developed in the form of modules and learning videos. After that, the prototype was validated by two experts in the field of teaching material development. The results showed that 20 students out of a total of 27 respondents saw that they needed the latest learning modules and videos that could make it easier for them to complete the subject matter because what had been used by lecturers so far still made it difficult for them to learn because the instruction and exposure to information did not meet the needs of students. The prototype modules and learning videos that have been developed are declared valid by experts in several aspects, namely self-instruction aspects, self-contained aspects, stand-alone aspects, adaptive aspects, and user-friendly aspects, so they are suitable for use by lecturers because they can help student’s complete lessons so that their learning outcomes can improve.

Cultivar una vida: una propuesta pedagógica de encuentros dirigidos a sobrevivientes del conflicto armado
Authors: López Flórez Jaison Steven
Published: March 2023

El 26 de septiembre de 2016 se firma la paz en Cartagena con el objetivo de finalizar un conflicto armado colombiano de más de medio siglo con las Fuerzas Armadas Revolucionarias de Colombia - Ejército del Pueblo (FARC-EP). Sin embargo, las iniciativas de Educación para la Paz tendrían un reto fundamental, construir paz en medio de la guerra. De esta manera, las escuelas se convierten en territorios de paz al desarrollar dinámicas pedagógicas en un posconflicto con secuelas de una sociedad afectada por la violencia, los reclutamientos forzados, el asesinato de líderes sociales, las desapariciones forzadas y los desplazamientos. En una guerra sin distinción de edad, son los niños, niñas y adolescentes quienes requieren transformar la violencia en perdón y reconciliación. Por ello, el artículo pretende promover una propuesta pedagógica dirigida a docentes y orientadores de Instituciones Educativas en Bogotá en jornadas extracurriculares para estudiantes sobrevivientes del conflicto armado de grado noveno, décimo y once, a través del papel del arte, del juego y de la cultura, teniendo como base el Enfoque de Acción sin Daño. Así mismo, se presenta la ejecución de la propuesta a través de la metáfora del árbol de la vida y los pilares de construcción de la memoria histórica, la reconciliación, la reparación simbólica y la cultura de paz, factores diferenciales entre otras propuestas pedagógicas desarrolladas en Colombia.
Competitiveness of international merchandise trade: The case of Poland
Authors: Radło Mariusz-Jan , Szarek-Piaskowska Aleksandra
Published: March 2023

The aim of the article is to present the possibilities that qualitative classifications of industries and goods introduce to the analysis of structural changes in the economy, as well as to assess changes in the international competitiveness of Polish merchandise trade in the long term. The article presents a review of the literature and the results of authors’ own research on the structure of Polish merchandise trade. The study uses Lall’s classification of goods which is relatively innovative and rarely used in the existing literature. By using this classification and the analysis of revealed comparative advantages (RCA) we also managed to assess the competitiveness of Polish exports. The research shows that since Poland’s accession to the European Union, the international competitiveness of Polish trade in terms of its technological level has changed only slightly. After the growth in the first years of Poland’s EU membership, the share of high technology products in the export structure stagnated in the 2010s and was still lower than that of medium or low technology products. Throughout the researched period, the RCA for high-tech products remained on the “foreign” side.
Participatory budgeting: Is it a useful tool towards co-creation of public services?
Authors: Dybał Mariusz
Published: March 2023

The research aim of the present paper was to check whether participatory budgeting fulfills the concept of co-creation of public services in Poland. To achieve this goal, the following research tasks have been implemented: (1) to identify the legal solutions of citizens’ cooperation, (2) to identify the characteristics of participatory budgeting in terms of co-creating public services, (3) to identify the amount and structure of participatory budgeting, (4) to provide cross-country comparison, and (5) to identify difficulties in using participatory budgeting. It has been revealed that in 2021, participatory budgeting was most popular in big cities where it is compulsory. In 2019, Poland (with 2,014 budgets) and Portugal (1,666 budgets) were responsible for 71.69% of all implemented participatory budgets in Europe. In 2018, Europe constituted 48.9% of all worldwide projects, mostly because of their compulsory nature in Poland and Portugal. Participatory budgeting might be successful in its implementation, but needs: involvement of the local community; planning of preparatory activities; communication between all entities involved in the project; appointment of a team that will coordinate the preparation of the participatory budget. According to the research, participatory budgeting is a platform for social activation and providing services better suited to the needs of the inhabitants. Participatory budgeting is a certain form of co-creating public services, as the inhabitants create projects and decide on the allocation of funds for the implementation of public services. Nevertheless, it is a limited version of co-creation, since residents are not involved in all parts of the process. The research covers mainly the years 2018–2022. In the present paper, the following research methods have been used: analysis of scientific literature and normative documents, co-creation methodology, comparative analysis, and statistical analysis.
Aging of the population and the quality of life
Authors: Gardocka-Jałowiec Anna , Szalonka Katarzyna
Published: March 2023

The paper aims at presenting the quality of life in terms of the deepening population aging process conditioned (to a great extent) by the progressive convergence of technologies. The interdisciplinary, theoretical nature of the considerations is a voice in the discussion on the interpretation, place, and role of quality of life, with particular emphasis on the extension of human life as a consequence of medical development.

The authors applied the descriptive analysis method to present the category of quality of life, the phenomenon of population aging, the specificity of technological changes, and selected issues in the field of demographic changes. Polish and foreign literature on the subject was the basis for the considerations. The theoretical aspect of the research is supplemented by the empirical part supported by available secondary data published by Eurostat and Statistics Poland (Główny Urząd Statystyczny).

Poland has been in the top thirty demographically old countries in the world for many years. In 1967, it crossed the threshold of demographic old age, and in 1980 — the threshold of advanced demographic old age. The demographic forecasts of Statistics Poland indicate that the number of people in retirement age will increase, and in 2035, it will reach 26.7% of the population. The observed and forecasted decline in the total population and the growth in the number of people in the senior age lead to an increase in the demographic dependency ratio of the elderly.

The convergence of technologies revealed in medicine creates a new perspective on the population aging process. Extending human life allows one to recognize that the quality of life becomes: 1. the most desirable result of all healthcare policies; 2. dependent on the change of the healthcare model, i.e., the transition from the dominant model of reactive and retrospective care to the desired proactive and prospective model.
Value-based medicine as an opportunity for the Polish health care system in a post-pandemic reality on the example of selected health programs
Authors: Czerska Iwona
Published: March 2023

The article aims to present the concept of value-based medicine (VBM) in the Polish health care system. The author reviewed the literature on the subject and formulated a research problem and two research questions to solve it. The issue of considering is health programs of the National Health Fund based on value. The author used professional scientific databases: Taylor & Francis online, PubMed, and Google Scholar to collect the bibliography. The literature on the subject covers mainly the years 2020–2022. First, the author presented the study’s theoretical framework by defining the EBM and VBM concepts, discussing the three main pillars of VBM, and highlighting its value limitations. Next, the author referred to the coronavirus pandemic and its impact on global health systems. The author characterized the current state of the health care system in Poland and listed its prospects for the post-pandemic future. Finally, the author presented three selected health programs based on the VBM model implemented in Polish healthcare: comprehensive coordinated care after myocardial infarction (KOS‑Zawał), POZ PLUS model, and comprehensive treatment of chronic wounds (KLRP-1 and KLRP-2). Of course, the discussed programs require further improvement and modification and may constitute the basis for developing other, new value-based programs. The value-based medicine model can complement the three branches of medicine — evidence-based, narrative, and integrative. Including these elements in the VBM model could benefit the entire health system, primarily medical staff and patients.

The study was done using three expert panels in which 28 start-ups participated. The research and its results are qualitative and are presented as a case study. The research was conducted by the authors in 2019 and concerns start-ups participating in cooperation networks, but its results could be interesting not only for start-ups, but also for everyone interested in the issues of cooperation between various entities and its potential to stimulate innovation.
Polska gospodarka w warunkach pandemii COVID-19 na tle Unii Europejskiej
Authors: Pancer-Cybulska Ewa
Published: March 2023

Celem artykułu jest ukazanie, jaki wpływ na polską gospodarkę miała pandemia COVID-19 w porównaniu do sytuacji w krajach członkowskich Unii Europejskiej. Chodzi o najważniejsze skutki gospodarcze, które wystąpiły w warunkach aktywnego wspierania gospodarki przez rządowy program antykryzysowy łagodzący negatywne skutki wywołane pandemią w latach 2020–21 (tarcza antykryzysowa). Analizie poddano program rządowy oraz wskaźniki rynku pracy — stopę bezrobocia i zmiany liczby pracujących w ujęciu branżowym. Sytuacja w Unii Europejskiej została omówiona z wykorzystaniem podstawowych wskaźników makroekonomicznych, jak dynamika wzrostu PKB oraz dług i wynik sektora ﬁnansów publicznych — każdy z tych wskaźników odnotował efekty zamknięcia gospodarki. Sekcje PKD „Zakwaterowanie i gastronomia” oraz „Handel; naprawy pojazdów samochodowych” najbardziej odczuły skutki kryzysu. Są też branże, które odnotowały pozytywne efekty działalności mimo lockdownu, na przykład „Informacja i komunikacja”. Wskaźniki sytuacji w Polsce w ujęciu makroekonomicznym sytuują ją w grupie krajów, które skutecznie przeciwdziałają skutkom pandemii, co dobrze wróży na okres odbudowy gospodarki po pandemii.
Rola przywództwa w rozwiązywaniu problemu wypalenia zawodowego w placówce medycznej
Authors: Tańska Ewa
Published: March 2023

Wypalenie zawodowe w placówce medycznej, szczególnie na pierwszej linii świadczenia usługi medycznej i po trudnym czasie pandemii COVID-19, jest pilnym wyzwaniem, które przywódcy powinni zrozumieć i bezpośrednio rozwiązać.

Celami artykułu są: 1) poznanie przyczyn oraz wpływu zmęczenia i wypalenia zawodowego na człowieka; 2) określenie roli przywództwa w tworzeniu kultury organizacyjnej opartej na angażowaniu zespołów i promującej dobre samopoczucie pracowników w placówce medycznej oraz 3) zaproponowanie strategii budowania atmosfery wzajemnego wsparcia oraz zapobiegania zmęczeniu i wypaleniu zawodowemu.

Metodą badawczą są przegląd i analiza literatury branżowej, w tym artykułów w międzynarodowych czasopismach oraz materiałów ze szkoleń.

W literaturze przedmiotu istnieje wiele deﬁnicji zjawiska wypalenia zawodowego. Jest to zespół wyczerpania emocjonalnego, depersonalizacji i obniżonego poczucia dokonań osobistych. W przypadku personelu medycznego depersonalizacja pacjentów może początkowo wyrażać się w tendencji do unikania osób chorych i skracania czasu spędzanego z nimi.

Czynnikami pierwotnymi wpływającymi na występowanie wypalenia zawodowego są brak uczciwości i wzajemnego szacunku, obciążenia, którymi nie można zarządzać, brak jasności ról, słaba komunikacja lub brak wsparcia ze strony przełożonego, nieuzasadniona presja czasu i brak ludzi do pracy, brak znaczących relacji międzyludzkich. Czynnikami, które pojawiły się w czasie pandemii, są rosnące zaległości, oczekiwanie na oddelegowanie do innej pracy oraz tak zwany koszt emocjonalny.

Kluczową rolą liderów na różnych szczeblach w hierarchii jednostki jest tworzenie kultury szacunku i ciągłego doskonalenia, która integruje członków zespołu we wzajemnym wspieraniu się w najtrudniejszych momentach pracy zawodowej. Niezwykle ważne jest wdrażanie strategii promujących budowanie i utrzymywanie dobrego samopoczucia i odporności pracowników na stres. Strategie te powinni indywidualnie do swoich potrzeb tworzyć ludzie, którzy doświadczają syndromu wypalenia. W zespołach medycznych warto zastanowić się, co personel medyczny zawdzięcza pacjentom, i ponownie dokonać oceny wartości, zbudować ich hierarchię i przemyśleć, co w życiu jest prawdziwe i cenne. Aby dojść do tak ważnych wniosków, niejednokrotnie trzeba omówić sprawy trudne i bolesne.

Authors: Vorob'ev Aleksandr , Budyukin Aleksey , Kondratyenko Vladimir , Samarkina Irina
Published: March 2023

Purpose: To show horizon to use new kind of public urban transport -autonomous tire tram of Phileas system

without guide middle rail and catenarian, with magnetic-electronic steering system application – as more

attractive for passengers than regular tram for urban transportations to free city lines from car jams. Methods:

Analysis and generalization of work experience of leading enterprises, which exploit given kind of transport, of

such countries as Netherlands (Eindhoven, Amsterdam), France (Due), Germany (Cologne), Turkey (Istanbul)

as well as South Korea and so on, were held. The analysis of the most progressive constructions, applied in

given vehicle, has been fulfilled. Results: Enterprise work experience has proved the feasibility to use tire tram

wagons without guide rail for cities but revealed whole series of drawbacks, connected with the imperfections

of the work of magnetic-electronic steering system that has whole row of irremovable flaws. Phileas rolling

stock has demonstrated itself as insufficiently reliable in exploitation that has led to its gradual premature

withdrawal and change with regular articulated buses, i.e. its conversion from a tram to usual BRT system.

Practical significance: The use of tire tram autonomous system without guide rail and catenerian has good

look-outs in cities but it’s necessary to apply more up-to-date element base for steering with the use of artificial

intelligence technology. Phileas transport system has simply got ahead of its time. It’s worth not to refuse from

the development of existing classical trams and light transport and the design of their new systems.

Practical significance: The considered approach in polymer element study and modernization makes it possible to obtain a polymer suite with force characteristic improved parameters – an energy intensity and completeness coefficients. Such polymer suites installed into draft gears can increase their reliability, increase the efficiency that in a whole can affect the safety of cars and goods they carry.
Factor Model of Vibrodynamic Load Effect on Pipeline Reliability
Authors: Postnova Elena , Runev Evgeniy
Published: March 2023

Purpose: To build a factor model of vibrodynamic loading influence on pipeline reliability based on the results of laboratory tests carried out taking into account the amplitude-frequency characteristics of the vibration process of the operating pipeline, obtained during full-scale tests at the railway station. On the basis of the factor model to determine the most significant factors affecting the reliability of pipelines under the action of vibrodynamic loading and to propose ways to improve their reliability. Methods: The plan of fractional factor experiment of 25-2 type was used to carry out laboratory tests of pipeline reliability under the influence of stresses of familiar constant cycle. The experiments were carried out on a test bench with a pulsating cylinder of type PC with a maximum load of 200 kN. Voltages were applied to the pipeline under test from control panels of static (from soil) and dynamic (from rolling stock) loads. Impulse shape was sinusoidal, the closest to natural one, cycle frequency — 300 c/min. The regression equation coefficients were calculated on a computer using the multiple linear correlation program. The significance of the regression coefficients was assessed by Student's test. Fisher's test was used to check the adequacy of the model to the experimental data. Adequacy of the regression equation to the physics of the phenomenon was tested using Student's test. Results: Tests of the pipeline with application of fractional factor experiment of 25-2 type allowed to build a factor model of the process under study in the form of polynomial of the first degree. It has been established that the main factors influencing pipeline reliability under vibrodynamic loading are train load, vibration amplitude of the pipeline and the depth of its embedding. The vibration frequency of the pipeline has no significant influence on the pipeline reliability. However, from the regression equation it follows that the pipeline vibration frequency depends on its diameter. Practical significance: The equation of linear regression is obtained, which is transformed by switching from coded values of factors to natural values, which can be used for practical purposes to determine the intensity of failures and the duration of operation of pipelines between failures.
Wirkfaktoren der kognitiven Verhaltenstherapie von Zwangsstörungen
Authors:   , Schubert Christiane
Published: March 2023

Zwangsstörungen gehören in Deutschland zu den vier häufigsten psychischen Störungen (Jacobi et al. 2014). Betroffene leiden unter deutlichen Einschränkungen ihrer Lebensqualität (Staketee, 1997). Durch kognitive Verhaltenstherapie mit Exposition und Verhinderung der Zwangshandlungen (sogenanntes Reaktionsmanagement oder Reaktionsverhinderung) existiert eine wirksame psychotherapeutische Behandlung (DGPPN, 2022). Für eine Optimierung der Behandlung in Bezug auf Ausmaß und Stabilität der Ergebnisse (Eisen et al., 2013; Foa & Kozak et al., 1996; Hohagen et al.,1998) ist es zentral ein vertieftes Verständnis zu erlangen, welche Faktoren im Therapieprozess für die Reduktion der Zwangssymptomatik verantwortlich sind. ?Nach erster Exploration der Literatur stellte ich die Hypothese auf, dass zu Wirkfaktoren auf Prozessebene für dieses Störungsbild noch zu wenig Forschung besteht. Vor diesem Hintergrund bietet der erste Artikel dieser publikationsbasierten Dissertation in Form eines systematischen Reviews einen Überblick über den Forschungsstand und bestätigt das vermutete Defizit (Schubert et al., 2018). Um zu einem weiteren Wissenszuwachs in diesem Bereich beizutragen, wurde eine naturalistische Studie mit 155 Zwangserkrankten im stationären Setting mit multiplen Messzeitpunkten durchgeführt. Basierend auf bisherigen Forschungsergebnissen wurde die Rolle der Wirkfaktoren nach Grawe (1995) sowie der Fähigkeit von Zwangserkrankten psychologisch flexibel zu sein als Variablen ausgewählt. Die in den weiteren zwei Publikationen aufgestellten Hypothesen gehen davon aus, dass die Reduktion der Zwangssymptome im Verlauf der Behandlung mit der Erhöhung der genannten Wirkfaktoren zusammenhängt. Zunächst wurde die einzelne Rolle der potenziellen Wirkfaktoren nach Grawe, nämlich therapeutische Beziehung, Ressourcenaktivierung, Motivationale Klärung, Problemaktualisierung und Problembewältigung geprüft. Hierbei gingen Ressourcenaktivierung sowie Problembewältigung als Wirkfaktoren für die Verringerung der Zwangssymptome hervor. Zudem erwiesen sich Problembewältigung und Motivationale Klärung als Prädiktoren für die Veränderung der Zwänge (Schwartz et al., 2016). Die Untersuchung psychologischer Flexibilität zeigte, dass die Variable zwar einen Einfluss auf die Reduktion und das Behandlungsergebnis der Zwänge hatte, jedoch nicht als Wirkfaktor für die Reduktion der Symptomatik zu verstehen ist (Schubert et al., 2022).

Discourse is a system of thinking, ideas, or thoughts describing a culture or speech characteristic in a certain period. This article focuses on the discourse of beautiful Sundanese women in Bandung. This research is studied using Michel Foucault’s theory of discourse, with the archaeological method of knowledge to determine the discontinuity between one knowledge and another. Data collection techniques with in-depth interviews and documentation study. The results of this study indicate that the discussion of beautiful Sundanese women in the city of Bandung is first, beauty is not only judged by physical appearance, but the assessment of beauty is based on behavior and thoughts; second, women are considered beautiful when they are grateful, confident, find their unique beauty, and love themselves; and third, there is no the same physical standard, however, Sundanese women in Bandung expect healthy and clean facial skin. This study concludes that the discourse of beauty in Sundanese women was formed as a form of expression to maintain and love themselves and not about specific predetermined standards of beauty.

The coronavirus (COVID-19) pandemic has affected social and economic sectors and has created new behavior and lifestyles. This article employs a quantitative methodological approach. Through interviews with 274 university students in East Java, Indonesia, the findings suggest that young people’s awareness of health behavior shifted after the spread of COVID-19. Before the pandemic, parents are struggling to have their children consume herbs. Youngsters consider herbs as a traditional lifestyle for the elderly. However, after COVID-19, the results suggest that young people are more supportive of herbal medicine in order to protect themselves from COVID-19. Therefore, it can be argued that COVID-19 pandemic generates a growing awareness for young people to consume herbal medicine, which becomes a new lifestyle and preserves the nation’s centuries-worth wisdom of the local culture.
Lifestyle changes in rural communities through spatial reproduction practices: A case study in Madiun Regency

The production of space in rural areas as a result of modernization changes lifestyles not only within families but also at a broader level, namely between communities. This study aimed to examine how spatial reproduction occurs in villages in Madiun Regency by identifying the dominant agent and the stages of the process of spatial reproduction. This study employed qualitative methods. This study found that there are four stages in the spatial reproduction process in Madiun Regency, including outreach, coordination, mutual cooperation, and synergy. These four stages occurred because of the presence of the village head as the initiating agent and Village Owned Enterprises (BUMDes) and the Tourism Awareness Group as organizations that oversee various community activities in the tourism sector. According to the findings of this study, technology has accelerated the process of spatial reproduction, which is reflected in the existence of four regionalizations, including economic, social, housing, and public services. This study concludes that the reproduction of space does not always lead to conflict and social inequality in society. On the contrary, people are able to work together in building shared prosperity with the value of mutual cooperation.
The Conservation Laws in Quantum Mechanics
Authors: Oldani Richard Joseph
Published: March 2023

When the theoretical foundations of Einstein’s quantum theory of radiation are compared with Heisenberg’s and Feynman’s theories of nonrelativistic quantum mechanics they are found to violate the conservation laws. The deficiencies are corrected by introducing Hamilton’s principle S = ∫ Ldt and applying the methods of quantum field theory to derive relativistic equations of motion. Based on the calculus of variations proof is given that the wave function equals twice the allowable action minimum.

In this study we sought to investigate the impact of urbanization, presence of concrete river bottom, and nutrient pollution on microbial communities along the L.A. River. Six molecular markers were evaluated for identification of bacteria, plants, fungi, fish, and invertebrates in 90 samples. PCA (principal components analysis) was used with PAM (partitioning around medoids) clustering to reveal community structure and an NB (Negative binomial) model in DESeq2 was used for differential abundance analysis. PCA and factor analysis exposed the main axes of variation but were sensitive to outliers. Differential abundance of Proteobacteria was associated with soft bottom sites, and there was an apparent balance in the abundance of organisms responsible for nitrogen cycling. Nitrogen cycling was explained by differential abundance of ammonia oxidizing archaea, the complete ammonia oxidizers Nitrospira sp., nitrate reducing bacteria Marmoricola sp., and nitrogen fixing bacteria Devosia sp. which were differentially abundant at soft-bottom sites (p adj < 0.002). In contrast, differential abundance of several Cyanobacteria and other anoxygenic phototrophs was associated with the concrete bottom sites, which suggested the accumulation of excess nitrogen. The soft bottom sites tended to be represented by differential abundance of aerobes, whereas the concrete-associated species tended to be alkaliphilic, saliniphilic, calciphilic, sulfate dependent, and anaerobic. In Glendale Narrows, downstream from multiple water reclamation plants, there were differential abundance of cyanobacteria and algae, however indicator species for low nutrient environments and ammonia-abundance were also present. There was differential abundance of ascomycetes associated with Arroyo Seco and a differential abundance of Scenedesmaceae green algae and cyanobacteria in Maywood, in the analysis which compared suburban with urban river communities. The proportion of Ascomycota to Basidiomycota within the LA River differed from the expected proportion based on published worldwide freshwater and river 18S data; the shift in community structure was most likely associated with the extremes of urbanization. This study indicates that extreme urbanization can result in overrepresentation of cyanobacterial species that could cause reductions in water quality and safety.
A Systematic Review: Rural Health Disparities During the COVID-19 Pandemic in the United States

Published: March 2023

COVID-19 has proven to be detrimental across the globe, most notably affecting the United States at an alarming rate compared to comparable countries. The pandemic has had multifactorial implications on the way communities in the United States prevent, prepare for, and address the virus; however, the impact of the pandemic on rural health is less well understood. Historically, rural communities have faced a unique set of challenges regarding accessing and receiving adequate healthcare, addressing chronic illness, and eliminating health disparities closely associated with the population’s socioeconomic status; the pandemic has exacerbated these challenges. The purpose of the current study was to conduct a systematic review of the literature to evaluate the effect of the COVID-19 pandemic on rural populations both at the individual and community level. Results indicated that rural health disparities increased both at the individual and system-wide levels as a direct result of the pandemic. Budget cuts significantly affected the infrastructure of rural hospitals resulting in them being unequipped to handle such high volumes of COVID-19 cases. The lack of infectious disease specialists, access to larger medical centers with substantial numbers of ICU beds and ventilators, and an overall lack of preparedness overwhelmed rural communities. Although comorbidities such as diabetes and heart disease were associated with poorer health outcomes for a multitude of reasons, the lack of clinic and physician availability for routine care during the pandemic further exacerbated the clinical link from COVID-19 positivity to comorbidities. Furthermore, mental health deteriorated as substance use increased to a greater extent in rural communities compared to urban, during the pandemic. This study shows that health comorbidities, mental health, substance use, health literacy, access to healthcare, among others can serve as key indicators for improving healthcare in rural communities. Future studies should seek to identify key issues that disproportionately affected rural communities in comparison to their urban counterparts considering the pandemic, as well as identify gaps in the availability of rural health resources that can improve the lives of millions of Americans now and during the next pandemic.
