Aglomeração urbana de Corumbá, Puerto Quijarro e Puerto Suárez: gênese e dinâmica econômica
Authors: Conte Cláudia Heloiza
Published: October 2022

O elemento central deste trabalho é a discussão sobre a dinâmica econômica da aglomeração urbana de fronteira de Corumbá/MS, Puerto Quijarro e Puerto Suárez/BO. Trata-se de uma das aglomerações mais dinâmicas da fronteira brasileira e que possui suas atividades econômicas fortemente ligadas a pecuária e ao comércio. Para o entendimento da dinâmica atual é fundamental a busca pela gênese e pelo processo de crescimento e desenvolvimento das cidades que compõem a aglomeração aqui estudada, bem como as relações mantidas entre elas. As cidades contaram com formações socioespaciais distintas, relacionadas com os interesses nacionais de cada país, mas sem permitir com que os fluxos e trocas entre elas deixassem de ocorrer.

Sabe-se que os eventos climáticos interferem nas atividades humana, pois apesar dos avanços tecnológicos o homem ainda não consegue influenciar os fenômenos naturais, sendo exposto a eles, principalmente quando se trata da agricultura de sequeiro que depende exclusivamente dos elementos climáticos para obtenção final da safra. O objetivo da pesquisa é analisar a produtividade da cultura do arroz no município de Caxias/Maranhão a partir da variabilidade da chuva na série temporal de 2000 a 2010 e sua influência conforme a compreensão da percepção das famílias produtoras de arroz. Os procedimentos metodológicos foram: levantamento teórico-bibliográfico e documental, visita e coleta de dados (chuva) junto à Estação Meteorológica de Caxias/MA, coleta de dados (produção de arroz) junto ao Instituto Brasileiro de Geografia e Estatística (IBGE), construção e aplicação de questionários a famílias produtoras de arroz em três distintos povoados (São Manoel, Pindoba e Sambaíba). Soma-se a utilização de tratamento estatístico para melhor manipular os dados. Os resultados do estudo apontaram que a irregularidade da chuva (favorecida pela influência da ZCIT, do El Niño e La Niña) condicionam totalmente a produção final do arroz, principalmente quando essa irregularidade torna-se mais evidente nas fases de nascimento e enchimento dos grãos, posto serem as mais sensíveis. Considera-se ainda, a percepção dos agricultores quando do período de preparo da terra, plantio e colheita, em que acontece no período mais chuvoso da região (entre os meses de janeiro e maio).

INTRODUCCIÓN: El exantema mucocutáneo inducido por Mycoplasma (EMIM) es una entidad separada del síndrome de Stevens-Johnson(SSJ) y el eritema multiforme (EM), descrita principalmente en adolescentes y en la que predomina la afectación mucosa sobre la cutánea.OBJETIVO: Describir nuestra experiencia en pacientes pediátricos afectos de EMIM.MATERIALES Y MÉTODOS: Estudio descriptivo retrospectivo en menores de 14 años con EMIM entre 2015 - 2020.RESULTADOS: Se diagnosticaron 6 pacientes, agrupándose 5 entre enero-abril de 2019. En 5 casos hubo afectación de mucosa ocular, faríngea y urogenital. Las lesiones cutáneas vesículo-ampollosas fueron las predominantes. En todos se aisló M.pneumoniae. Debido a la afectación mucosa, 4 pacientes precisaron nutrición parenteral y 3 sondaje urinario. En 5 se prescribió tratamiento inmunomodulador con corticoides sistémico e inmunoglobulina intravenosa. La evolución fue favorable y la secuela más frecuente fue la xeroftalmia.CONCLUSIÓN: A pesar de la similitud clínica del EMIM con el SSJ y el EM, debemos sospecharlo en adolescentes con predominio de afectación mucosa. La evolución de nuestros pacientes fue favorable con tratamiento de soporte e inmunomodulador. Son necesarios estudios bien diseñados para establecer que pacientes se benefician de tratamiento con corticoides y/o inmunoglobulina.

La hiperamonemia aguda (HAA) es una urgencia médica que causa daño neurológico y puede conducir a daño neurológico o incluso la muerte. En los pacientes con errores innatos del metabolismo (EIM) se presenta con mayor frecuencia, sobre todo en eventos de descompensación metabólica, ameritando atención de terapia intensiva. Los EIM que principalmente causan HAA incluyen los defectos del ciclo de la urea, acidemias orgánicas, defectos de oxidación de ácidos grasos y los defectos del ciclo de la carnitina. Ante un evento de HAA el objetivo primordial es preservar la vida y la integridad del sistema nervioso central, disminuyendo los niveles sanguíneos de amonio hasta valores normales, mediante tratamiento médico urgente, soporte vital y nutrición individualizada. El conocer los medicamentos y métodos disponibles para la remoción del amonio, así como las necesidades energéticas, proteicas, suplementos, cofactores y vitaminas, es muy importante para la correcta toma de decisiones médicas y nutricionales en cada paciente tomando en cuenta su condición clínica, bioquímica y enfermedad de base. El objetivo de este trabajo es presentar conceptos actuales sobre el tratamiento de la HAA en pacientes con EIM.

What Makes People Cry? A Preliminary Analysis of Situations that Evoke Emotional Tears
Authors: Wągrowska Julia , Wróbel Monika
Published: October 2022

The aim of two preliminary studies reported in the article was to identify the main reasons for crying and to create a set of situational vignettes that would refer to specific situations or events that potentially can make people cry. In Study 1 (n = 61), we asked the participants to list six general reasons behind crying. In Study 2 (n = 70), the participants were asked to identify specific situations in which people shed emotion-related tears. As a result, we selected a set of 34 situational vignettes. Each of them is a short and gender-neutral description of a specific emotional reason that can make people cry and is related to one of the following basic emotions: happiness, sadness, anger, or fear. The vignettes can be used to manipulate the emotional basis of tears in experimental research.
Using Competing Theories to Explain Variations in U.S. Police Departments’ Reported use of Force Counts
Authors: Riles Sabrina
Published: October 2022

Using data from the 2013 Law Enforcement Management and Administrative Statistics (LEMAS) survey, the current study provides a cross-sectional analysis of U.S. police departments’ reported use of force. The goal of this study was to examine the extent to which departments’ reported force counts were explained by rational bureaucratic and/or institutional theory. Given the stark variations in reported force counts, a hurdle model was used to examine the potential effects of the theories on departments’ likelihoods of reporting force and the frequency in which they reported it. The results highlighted the significance of both theories. In terms of rational bureaucratic theory, the results illustrate that the absence of a collective bargaining agreement and greater professionalism requirements reduced departments’ likelihoods of reporting force, while less restrictive administrative policies increased departments’ likelihoods of reporting force and the frequencies in which they reported it. In terms of institutional theory, the results revealed that black officer representation reduced both the likelihood of reporting force and the frequency of force reported. However, increases in jurisdictions’ population and crime rates, for the most part, increased force reports. Combined the theories explained over one-fifth of the variations in departments’ reported use of force for the observed year. The findings suggest that successful efforts to reduce force-related injuries and deaths should consider the contextual environments in which rules and regulations regarding force are made.

Published: October 2022

Medical grand rounds as a key teaching exercise originating from the bedside rounds conducted by prominent clinicians. Traditional (face-to-face) Ground Rounds have been robust in medical education that can update students 'information and help students' clinical decisions in treating their patients. Due to the Coronavirus Disease of 2019 (COVID-19) pandemic and its effects on different aspects of life, including education, most medical universities have begun to use online education as a new way to provide medical education, and online classes have become one of the common teaching methods. Virtual Grand Round sessions were implemented to facilitate continuity of care. Implementing virtual grand rounds during the pandemic period and considering the results and effectiveness from the perspective of students as direct benefactors can provide a good understanding of the potential of this method of e-learning. This article provides an overview of which medical disciplines have used the virtual Grand Round program for education during the COVID-19 pandemic and what are the benefits and results.

Published: October 2022

Background: Limited data exist on the clinical outcomes of patients with coronavirus disease 2019 (COVID-19) presenting with ST-segment-elevation myocardial infarction (STEMI).
Methods: This multicenter study, conducted in 6 centers in Iran, aimed to compare baseline clinical and procedural data between a case group, comprising STEMI patients with COVID-19, and a control group, comprising STEMI patients before the COVID-19 pandemic, and to determine in-hospital infarct-related artery thrombus grades and major adverse cardio-cerebrovascular events (MACCEs), defined as a composite of deaths from any cause (cardiovascular and noncardiovascular), nonfatal strokes, and stent thrombosis.
Results: No significant differences were observed between the 2 groups regarding baseline characteristics. Primary percutaneous coronary intervention (PPCI) was performed in 72.9% of the cases and 98.5% of the controls (P=0.043), and primary coronary artery bypass grafting was performed in 6.2% of the cases and 1.4% of the controls (P=0.048). Successful PPCI procedures (final TIMI flow grade III) were significantly fewer in the case group (66.5% vs 93.5%; P=0.001). The baseline thrombus grade before wire crossing was not statistically significantly different between the 2 groups. The summation of thrombus grades IV and V was 75% in the case group and 82% in the control group (P=0.432). The rate of MACCEs was 14.5% and 2.1% in the case and control groups, respectively (P=0.002).
Conclusion: In our study, the thrombus grade had no significant differences between the case and control groups; however, the in-hospital rates of the no-reflow phenomenon, periprocedural MI, mechanical complications, and MACCEs were statistically significantly higher in the case group.

Published: October 2022

Background: Patients with mitral valve prolapse (MVP) may reveal symptoms of autonomic dysfunction and heart rate variability (HRV). We sought to explore the autonomic nervous system in children with MVP.
Methods: This cross-sectional study enrolled 60 children aged between 5 and 15 years with MVP and 60 age- and sex-matched healthy children as controls. Two cardiologists performed electrocardiography and standard echocardiography. HRV parameters were explored via 24-hour rhythm 3-channel Holter monitoring. The depolarization of ventricular and atrial parameters, comprising QT max and min, QTc intervals, QT dispersion, P maximum and minimum, and P-wave dispersion, was measured and compared.
Results: The mean age was 13.12±1.50 years in the MVP group (F/M: 34/26) and 13.20±1.81 years in the control group (F/M: 35/25). The maximum duration and P-wave dispersion in the MVP group were signiﬁcantly different from the healthy children (P<0.001). The longest and shortest QT dispersion values and QTc values were signiﬁcantly different between the 2 groups (P=0.004, P=0.043, P<0.001, and P<0.001, respectively). The HRV parameters were signiﬁcantly different between the 2 groups, too.
Conclusion: Decreased HRV and inhomogeneous depolarization showed that our children with MVP were prone to atrial and ventricular arrhythmias. Furthermore, P-wave dispersion and QTc could be used as prognostic markers of cardiac autonomic dysfunction before it is diagnosed by 24-hour Holter monitoring.
Tracheobronchial Tree Ossification in a 5-Year-Old Boy with Keutel Syndrome: A Case ReportTracheobronchial Tree Ossification in a 5-Year-Old Boy with Keutel Syndrome: A Case Report

Published: October 2022

Keutel syndrome (KS) as a scarce autosomal recessive disorder is characterized by hearing loss, multiple peripheral pulmonary stenoses, abnormal cartilage calcification, and morphological defects including midface hypoplasia and brachytelephalangism. We herein describe a 5-year-old boy who was referred for the evaluation of incidentally auscultated heart murmurs. He had no obvious abnormalities at birth but suffered from recurrent episodes of infectious otitis media during infancy.
Physical examination revealed facial abnormalities, such as a broad nasal bridge, a sloping forehead, maxillary hypoplasia, and brachytelephalangism. Chest radiography showed tracheobronchial tree calcification. Transthoracic echocardiography illustrated peripheral pulmonary artery stenosis, moderate tricuspid regurgitation, and pulmonary hypertension.
Computed tomography angiography confirmed calcification and segmental stenosis in the peripheral pulmonary arteries.
The patient was diagnosed with KS. Most of these patients have a good prognosis. During the follow-up of these patients and examinations, we should pay attention to their symptoms related to upper respiratory tract infections, the extent of hearing, and the possibility of tracheal and pulmonary artery stenosis development.
KS is a disease with a good prognosis, and a careful initial examination of babies, including facial appearance and heart auscultation, may lead to the early diagnosis of this disease.
The proof of instantaneous gravitation
Authors: Gimsa Andreas
Published: October 2022

According to Newton, the changes in the gravitational field propagate instantaneously. If we examine the earth on its orbit around the sun and assume a light-fast effect of the gravitation, the following situation would occur: Through the sun, a force would not act directly on the earth's center of gravity, but on the point where the earth's center of gravity was 8 minutes ago, and through the earth, a force would not act directly on the sun's center of gravity, but on the point where the sun's center of gravity was 8 minutes ago. This time delay would cause the Sun-Earth distance to build up and the Earth to leave orbit. We would be dealing with unstable orbits of orbiting masses in space. However, this is not observed.

It is to be proved that the gravity with 1. the constant product of mass and time duration which passes on it, 2. the time dilation, and 3. the permanent enlargement of stable orbits can be described exactly by the Newton's basic law. Newton would continue to apply and describe gravity physically correct in accordance with observation. As a conclusion, there should be an instantaneous gravitational propagation.
Recovering Seismic Sensor Data on Arrival Time Differences for Longitudinal and Transverse Seismic Waves
Authors: Aslanov T.G.
Published: October 2022

We developed a method for seismic sensor data recovery and simulated seismic sensor operation using artificial neural networks. We selected two parameters to train the artificial neural network on: the time between seismograph recordings of longitudinal (primary) and transverse (secondary) seismic waves, as well as the time between primary seismic wave recordings by two seismographs located at a certain distance from each other. We used data on 2636 earthquakes that occurred in 2020 in the Republic of Dagestan for our seismograph data recovery. The existing 19 seismic stations recorded less than 60 % of the total number of earthquakes. To recover seismic data, we trained the neural network twice for each seismic sensor, the first time involving zero time differences regarding seismic wave arrival at seismographs that did not record the time, and the second time involving time differences recovered from the results of training the neural network for the first time. Times between seismic wave recordings with known data were used as inputs to train the artificial neural network, while time differences to be determined were designated as outputs. The trained neural network displays a correlation coefficient related to real time intervals between seismograph recordings of seismic waves that exceeds 0.99919. The paper provides root-mean-square error plots of the neural network operation by epochs of its training, plots demonstrating how training results calculated by the neural network matchthe initial data, and histograms of neural network operation errors

Published: October 2022

An increase in the fuel efficiency of small-sized gas turbine engines can be achieved by regenerating the heat of the turbine exhaust gases. A rational layout solution in this case is a turboshaft scheme, where the effective power is generated on the shaft of a free turbine, and the turbine exhaust gases are released into the environment without doing useful work. When creating a turboshaft engine with heat recovery, the concept of developing engine family on the base of unified gas-generator was considered. The concept involves the development of a modular system, where the addition or exclusion of individual large units allows changing the type of engine at minimal cost. The article presents the layout solution of a small-sized turboshaft gas turbine engine with heat recovery, developed on the basis of a unified gas-generator and using a gearbox to transfer effective power to a propeller or a rotor. A plate heat exchanger module with a corrugated heat exchange surface for a small-sized turboshaft gas turbine engine has been designed. The heat exchange matrix was developed using a complex techniques of computer-aided design, calculation and manufacture of plate heat exchangers. Some design features of high-temperature plate heat exchangers are identified, the most important of which is the non-uniformity of temperature fields in the heat exchange matrix. Taking into account the non-uniformity of temperature fields, the heat exchanger module is a collapsible structure allowing the replacement of the heat exchange matrix and providing compensation for thermal expansion of the heat exchanger elements. The designed plate heat exchanger module for a small turboshaft gas turbine engine will be manufactured and tested on the bench

The edition of Kalisz, as it was censored by the Jesuits from Kalisz for the needs of education in the colleges of the order, cannot constitute the basis for a new edition on its own. We only have the notes of Aloj­zy Kowalkowski, who compiled the manuscript with the Kalisz edition before World War II. As the individual copies of the Kalisz edition differ, relations between them should be established.

Ortografia nie do wiary. Wątpliwe bluźnierstwo i bóg
Authors: Tramer Maciej
Published: October 2022

Po śmierci Władysława Broniewskiego Mieczysław Grydzewski zwrócił uwagę na, jego zdaniem, kontrowersyjny zapis słowa „bóg” w bardzo dobrze znanym polskiemu czytelnikowi wierszu Zagłębie Dąbrowskie. Laickie poglądy poeta deklarował na długo przed debiutem. Przez cały okres swojej działalności literackiej konsekwentnie stosował zapis korzystający z małej litery w pisowni słowa „bóg”. Nie czynił tego wbrew regułom, lecz pomimo zasad przyjętych przez polską ortografię. Zamiarem nie było bluźnierstwo, lecz wyłączenie się z opresywnej reguły uznający istnienie monoteistycznego „boga” jako bezdyskusyjny pewnik. Po przełomie 1989 roku część edytorów i badaczy uznała nawet stosowany przez Broniewskiego zapis jako wymuszony przez stalinowską i peerelowską cenzurę i starała się dokonać korekty.

Published: October 2022

Preschoolers’ task persistence during classroom instruction has become a thing of concern to parents, education stakeholders and the general public. This lack of task persistence by pre-schoolers during classroom instruction may be attributed to the teachers’ classroom management practices. This study was therefore carried out to determine the extent to which teachers’ classroom management practices can predict preschoolers’ task persistence. The purpose of this was to determine the predictive ability of teachers’ classroom management practices on preschoolers’ task persistence. The study employed both descriptive and correlational research designs. 5 preschool educators and 156 pupils were purposively sampled for the study. The instruments for data collection were developed by the researchers from literature reviewed. The research questions were answered using mean and Pearson Product Moment Correlation Analysis while the hypothesis was tested at 0.05 using Regression analysis. The result of the study showed that teachers’ classroom management practices is a significant factor in determining pre-schoolers’ task persistence. The study concluded that teachers’ classroom management practices is a significant predictor of pre-schoolers’ task persistence. It is therefore recommended that early childhood educators should always adopted an effective classroom management practices that will enhanced and promote preschoolers’ task persistence during classroom instructions.

Published: October 2022

This study aims to evaluate the effect of training on the ability of teachers to implement 21st-century skills learning at the Construction Engineering Vocational School in Yogyakarta. According to the training objectives, descriptive and inference statistics methods measure teacher learning achievement in developing 4C skills. A total of 42 Vocational High School teachers were taken as samples, representing three groups of subjects, basic subjects of expertise (C1), basic skill programs (C2), and competency skills (C3). Data analysis was carried out using descriptive analysis techniques and Manova analysis. Content validation of the research instrument was carried out through expert judgment involving three experts, and the instrument was declared valid, with the Aiken V coefficient of 0.60. The results showed: (1) the level of implementation of learning to develop 4C skills (critical thinking, creativity, collaboration, and communication) at the Construction Engineering Vocational School in Yogyakarta in the good category; (2) obstacles to the implementation of 4C learning are related to teachers' understanding of low 4C learning, overloaded teacher workloads, and the academic abilities of Vocational High School students who are at medium and low levels; and (3) the level of implementation of 4C learning between subject groups is significantly different, while that based on teacher participation in 4C learning training is not significant.

A Mathematical Model to Evaluate the Impact of Yoga Poses on Body
Authors: NOROZPOURSİGAROODİ Sajedeh
Published: October 2022

Daily Yoga activities are part of a ten-posture series with linked relaxation and aerobic exercise, resulting in a balancing of flexibility and extensions. Because this series is often repeated and advocated by several yoga professionals, structural modeling to justify its purported health advantages is needed. Older is recommended to do more workouts to maintain activity, given the increasing pressures in societal, economical, and health issues as a result of the elderly society. They are, regrettably, unable to do so due to a variety of physical and psychological obstacles. The whole body form changes significantly as people get older, and sag. One of the most important variables in regaining their drive and comfort throughout social activities might be the layout of their apparel. The impact of athletics on older is investigated in this study. Depending on rigid body movements and free-body diagrams, a numerical model is built for each position in the yoga exercises. The idea of static equilibrium is used to calculate the forces and moments that different joints experience. The model given in this study was developed under a variety of assumptions. But what is discovered in practice is that the knees carry the maximum joint action while the ankle and wrist are discovered to play a major part in transferring the ground response forces throughout yoga. Thus, it would imply that the model is a good tool for forecasting the forces and durations that happen not just during the yoga positions but also during other situations.
Theories of Change for WFP Afghanistan’s Contribution to the Triple Nexus: Policy Note
Authors: Sida Lewis , Nelis Tina
Published: October 2022

The World Food Programme (WFP) has been a key humanitarian force in Afghanistan since 1963 and remains the largest agency in the Humanitarian Response Plan for Afghanistan. Whilst its focus has primarily been its humanitarian mandate, prior to the Taliban takeover, WFP had been working to see how its strategic outcomes in the 2018 Country Strategic Plan (CSP) were aligned with viable peace and development efforts nationally. The Taliban takeover has accelerated an already deteriorating humanitarian crisis. Drought in 2021 had left many in the west of the country in need of humanitarian assistance. The collapse of international support, and the freezing of the banking system and assets held overseas has exacerbated already very high levels of poverty and threatened the price of staples in the market. This has necessarily focused all external efforts on the humanitarian response. Despite the severity of the humanitarian situation, WFP is keen not to entirely neglect development and peace aspects, knowing that both are essential to the future of Afghanistan. This short note sets out the likely medium-term policy framework and some considerations for WFP in navigating this. This Policy Note should be read in conjunction with the longer document Theories of Change for WFP Afghanistan’s Contribution to the Triple Nexus: Final Report (Sida and Nelis 2022).
Vivacidade na praça da paz em João Pessoa - PB

Published: October 2022

Este artigo identifica relações da configuração espacial e forma construída com os usos na Praça da Paz, em João Pessoa – PB. A Praça da Paz está situada centralmente no bairro Bancários, perto de equipamentos atratores de fluxo na cidade. Entendendo que o uso dos espaços públicos pode ser influenciado pela localização, entorno e organização espacial, procura-se investigar como a localização, a disposição interna de equipamentos e o desenho da praça podem estar facilitando ou dificultando usos e permanência de pessoas no espaço. O aparato teórico-metodológico da Sintaxe Espacial foi usado para investigar características formais de localização na cidade e de padrões espaciais na praça e entorno imediato, definindo diferentes tipos de barreiras e permeabilidades para o movimento a pé e campos de visão na praça. Os resultados enfatizam que a praça está situada em uma centralidade da cidade em termos de movimento potencial, com comércios e serviços, que naturalmente atraem mais pessoas. Achados apontam que os caminhos informais integram melhor o espaço, e que o setor noroeste da praça é pouco visível, desconectado e pouco usado, destacando algumas limitações do projeto formal da praça. Mesmo assim, a disposição de equipamentos para uso e estadia junto a caminhos principais – como o eixo central - é positiva ao distribuir pessoas na maior parte da praça. A facilidade de ver e de se movimentar pelo acesso principal convidam pessoas a pararem e a passarem na praça, caracterizando a Praça da Paz um local bem animado.

Pesticide use is a common practice worldwide, especially in Sub-Saharan African (SSA) countries, where ongoing agriculture intensification and the need for disease vector control make it essential. The population can thus be exposed to variable amounts of pesticides through the diet. Edible insects are a highly regarded food source in SSA. However, they are still mostly harvested from the wild, where chemical applications are not necessarily controlled, representing a major cause of concern for consumers. We investigated residues of legacy (OCPs) and current-use pesticides (CUPs) in selected edible insects commonly consumed in Uganda and Nigeria, and evaluated the eventual health risk for the adult population associated with their consumption. Targeted OCPs were < LOQ in all analysed edible insects, except for hexachlorobenzene (up to 0.87 ng/g dw), while several CUPs were present at notable levels. Cypermethrin showed the highest median concentration (17 ng/g dw), while the Nigerian cricket Brachytrupes membranaceus was the most contaminated sample, with concentrations of aldicarb, propoxur, chlorpyrifos, dichlorvos and paclobutrazol reaching 118 ng/g dw, 327 ng/g dw, 156 ng/g dw, 26 ng/dw, and 14 ng/g dw, respectively. The concentrations of pesticides were generally well below the available maximum residue levels (MRLs), and the dietary risk assessment did not indicate health threats for the adult population. However, we suggest that the monitoring of the chemical safety of edible insects in SSA should be further investigated and insects should be integrated into more extensive dietary studies.
Examining learning difficulties and alternative conceptions students face in learning about hybridization in organic chemistry

Chemistry education research has demonstrated that chemistry concepts are abstract, complex, and challenging for students to learn and understand. Chemistry is the branch of science that deals with the nature and behavior of atoms, and bond formation and hybridization both play a crucial role in the discipline. The concept of hybridization deals with the description of the formation of hybrid orbitals, the prediction of bond angles and molecular geometry, and the reactivity of some organic compounds. Development of conceptual understanding of hybridization is important for effective learning about bond formation, molecular structure, bond angle, acidity, and reactivity. This research study aimed to examine alternative conceptions that students hold; the challenges that students face in learning about hybridization; and the strategies that they use to solve hybridization problems. The investigation took place at the City College of New York, an urban, minority-serving institute. Our method of data collection comprised a survey made up of Likert-type, open-ended questions as well as a hybridization-related set of problems. The number of research participants was n = 103. Our research findings suggest that developing conceptual understanding of organic chemistry concepts such hybridization and resonance structures, then relating it to the structure of molecules, is crucial to its function. The presentation of concepts such as hybridization in an oversimplified manner and students’ reliance on memorization in learning can hinder students’ development of conceptual understanding and meaningful learning. Students misestimate their competencies and abilities which can negatively impact poor performers and prevent them from addressing deficiencies in learning about hybridization. We suggest that instructors present the topic of hybridization at the three levels of representations, provide students with opportunities for active learning and knowledge construction, and nurture students’ visualization of atomic and hybrid orbitals.

Published: October 2022

Mortality in birds engaged in mobbing potential predators is rare, especially while defending their progeny. This paper reports an incident of a nesting Crested Pigeon Ocyphaps lophotes being fatally attacked by an Australian Raven Corvus coronoides that it was mobbing. The Raven remained on the carcass for some time, but did not feed on it.
Comparative Analysis of Companies' Financial Performance Before and After Mergers and Acquisitions (Study on Companies Listed on the IDX and Conducting Mergers and Acquisitions in 2017)
Authors: Shoimaturrohmah Binti , Zulkifli Makhmud
Published: October 2022

This study aims to determine the differences in the company's financial performance between before and after mergers and acquisitions. The financial performance used in this study is data three years before and three years after mergers and acquisitions. In this study, the company's  financial performance was measured using seven ratios. The ratios used include Quick Ratio (QR), Return On Assets (ROA), Return On Equity (ROE), Debt Ratio (DR), Debt To Equity Ratio (DER), Total Assets Turnver (TATO)  and Earning Per Share ( EPS). The sample used in this study were 5 companies that carried out mergers and acquisitions in 2017 and were listed on the Indonesia Stock Exchange. Sampling was done by purposive sampling method. The data analysis technique in this research is descriptive statistical analysis. Testing the normality of the data using the One Sample Kolmogorv Smirnov test. The different test used was the Paired Samples T-test for data that was normally distributed and the Wilcoxon Signed Rank test for data that was not normally distributed. The results of this study indicate that QR and DER show a significant difference between the three years before and three years after mergers and acquisitions. While the other ratios,  namely ROA, ROE, DR, TATO, and EPS showed no significant difference between before and after mergers and acquisitions.
Sobre la 33 conferencia de Freud: "La feminidad"
Authors: Toribio Caballero Sandra
Published: October 2022

In his 1932 lecture on "Femininity," Freud reviews some aspects that he considers fundamental in his understanding of women. Despite the fact that the text was written almost a century ago and there are aspects that are clearly outdated, its reading does not leave us indifferent. Why? Because despite the passage of time, some of the conceptions about femininity of that moment are still very present today. Freud addresses in his text issues such as upbringing, motherhood and sexuality. Can something be rescued from its conception in these themes? The text reviews these and other issues from a gender perspective, taking into account Freud's androcentrism, which runs through his theory and concepts (such as penis envy).
Estudio Cualitativo: La Experiencia Subjetiva de Personas con Diferentes Niveles de Mentalización Durante la Pandemia por COVID-19
Authors: Rodríguez-Quiroga Andrea
Published: October 2022

INTRODUCTION: In order to understand the unrest caused by the COVID-19 lockdown, a mixed-design research was carried out, the general objective was to determine the relationship between mentalization, loneliness and internalizing symptoms. OBJECTIVE: This article corresponds to the third, qualitative phase. It proposed to explore the subjective experience of people with different levels of mentalization during the COVID-19 pandemic. METHOD: For this, 14 semi-structured interviews, designed according to the variables were carried out. The Consensus Qualitative Consensus Research (CQR) methodology (Hill et al., 1997, 2005) was used for data analysis. RESULTS: According to the frequency of appearance of the categories, it was found, as a general category, that it was the relationship with others that allowed the participants to cope with the situation. Typically, strategies to cope with discomfort, the negative impact of the pandemic on work, and feelings of sadness and anxiety were highlighted. Discursive differences were found according to the level of mentalization, reflecting a progression in relation to the person's register and possibilities of agency. DISCUSSION: We propose the implementation of mentalization interventions to moderate the negative effects of this and future crises.
El arte en los procesos de transformación del Self. Lienzos oníricos
Authors: Ibarra Zazueta Karen
Published: October 2022

The meeting experience in the analytic relationship opens up the possibility of transformation, both the dreams and the artistic productions of patients are elements that, together with their pre-verbal expressions, enable deep communication between patient and analyst, opening up a space for intersubjectivity. These elements take on special relevance when there are internal conflicts in which aggressive, reifying links have been experienced, which become an internal dynamic in which the true self is internally cloistered
Saliendo de la oscuridad de la inexperiencia de la mano de Sullivan y Buechler
Authors: Pérez Álvarez Gerardo
Published: October 2022

Entering clinical practice and being a novice psychotherapist presents a challenge for many, walking through the first steps in this profession produces anxiety and a feeling of vulnerability. This paper is meant to share the emotional and therapeutic difficulties I went through at the beginning of my clinical practice. Some theoretical, but mainly practical concepts from Harry Stack Sullivan and Sandra Buechler have helped me bear the struggles of the novice experience in the clinical setting and have also helped me locate paths for therapeutic action. Mostly, I emphasize on the importance of curiosity, not only as an emotion, but also as a clinical value that allows us to deepen in the therapeutic experience. Curiosity, along with an active inquiry, guide us ahead of the uncertainties and ambiguities of the professional work experience. Coming out of the novice darkness experience has been possible due to the calm, inspiration, and guidance that these two authors have offered me throughout their works.

Published: October 2022

La pandemia provocada por la COVID-19 es una crisis sanitaria que ha ocasionado un gran impacto en el sector turístico a nivel mundial. A mediados del mes de marzo de 2020, en España se paralizó toda la actividad turística, restringiendo la demanda de bienes y servicios relacionados con el turismo con medidas como el cierre de fronteras, la restricción de la movilidad no esencial y el confinamiento domiciliario. Este artículo analiza el impacto de la pandemia en el sector turístico de cada una de las Comunidades Autónomas españolas, cómo ha afectado esta crisis sanitaria en la recepción de viajeros y, como consecuencia, en el número de pernoctaciones de estos, además de poder conocer qué tipo de alojamiento (hoteleros, extrahoteleros y rurales) ha visto mermada más su demanda turística. Los resultados obtenidos confirman los efectos negativos que ha sufrido la actividad turística debido a la pandemia y la incidencia de esta en cada Comunidad Autónoma que ha acentuado los desequilibrios existentes en el sector turístico provocando un punto de inflexión antes y después de esta crisis sanitaria.
