Exploring the adoption of desktop simulators in pilot training: An ethnographic approach
Authors: Marques Elvira , Carim Junior Guido , Campbell Chris , Lohmann Gui
Published: November 2022

Aviation has been using flight simulators for pilot training for a long time. Desktop simulators are a more cost-effective, efficient and accessible alternative to an expensive high-cost, high-fidelity flight training devices. Despite the benefits, desktop simulators are rarely seen in flight schools and flight instructors hardly recommended them for early stages of training. Therefore, this study investigated the perception of flight instructors about the usefulness of desktop simulators in flight training and the ways they can be used in the early stages the training. An ethnographic study was conducted in a flight school in Australia via observation and in-depth interviews. Despite the documented benefits of using desktop simulators, there seems to be a hesitancy by flight instructors to encourage students to use these devices because students: build bad habits if they misinterpret what they have been taught and practise without supervision, tend not to trim the aircraft, apply too much force on the controls, and look down at the instruments very often and do not look out. We conclude that this negative perception about the technology can be holding back further progress in improving the quality of flight training and preventing students from embracing the technology to enhance their learning.

Authors: Cram Andrew , Harris Lynne , Raduescu Corina , Huber Elaine , Zeivots Sandris , Brodzeli Andrew , Wright Sue , White Amanda
Published: November 2022

Whilst most institutions have been using online assessment submission for many decades, the move to fully online delivery during the COVID-19 pandemic meant more traditional forms of assessment also had to move online. In this national study we captured a snapshot of online assessment usage across business disciplines from 97 survey participants from universities in Australia and identified the challenges reported by participants. We found the three most predominant forms of online assessments are written reports and essays, online exams/quizzes and live or recorded presentations. We categorised the reported challenges into 13 groups, and they include academic integrity; additional time and effort for teachers; technology access and service consistency; student preferences and expectations; and changes to feedback. We conclude with a discussion on these challenges. This study contributes not only a better understanding of the usage of online assessment in Australian business education, but also provides a benchmark with which to track and evaluate future shifts in assessment practice.
The impact of an anatomy and physiology open textbook on student satisfaction and engagement in a regional Australian university
Authors: Chruscik Anna , Kauter Kate , Windus Louisa , Whiteside Eliza
Published: November 2022

The rising cost of tertiary study-related expenses, including textbooks, has been shown to influence enrolment rates, course choices and quality of learning experiences and outcomes for students. To address issues related to affordability and accessibility, the University of Southern Queensland (UniSQ) has recently implemented alternative learning materials through open educational resources (OERs). Published by UniSQ in 2021, the ‘Fundamentals of Anatomy and Physiology’ is an opensource, online textbook provided as a supplementary resource for students undertaking first-year anatomy and physiology courses. To investigate student satisfaction and the overall usefulness of implementing this textbook into undergraduate courses, responses to a student feedback survey were analysed. The main themes that emerged from the qualitative feedback included 1. increased student accessibility to course information, 2. improved tertiary education affordability, 3. enhanced course content comprehension, 4. provisioned student agency and choice to interact with formats that best suited the student learning context and 5. overall was rated as a beneficial and useful resource. Although the majority of students who responded to the survey (56%) did not have any negative perceptions about the online textbook per se, there were two negative response themes that emerged regarding the user interface and internet connectivity. Further evaluation regarding retention rates and overall achievement remains to be addressed.
How can EdTech support graduate employability?
Authors: Kitto Kirsty
Published: November 2022

Pressure is mounting upon universities to ensure that our graduates are employable. Business and governments increasingly demand that graduates are equipped with skills and competencies that map into labour market needs. But students often struggle to choose courses, subjects and activities that will support their career goals and aspirations. This paper introduces an approach designed at UTS which aims to embed a skills analytics tool at key transition points for our students. The need to support such tools will a well-grounded learning design is discussed, along with the need to move beyond a “one size fits all” model for supporting EdTech tools. A solution that utilises a series of modules in the LMS is introduced.
Developing a micro-credential for Learning Designers: A Delphi Study
Authors: MacCallum Kathryn , Brown Cheryl
Published: November 2022

Teaching and learning online have increased as a consequence of the pandemic. There is an increasing need for learning design proficiency both in terms of new roles and also new expertise.  In recognition of this, the Tertiary Education Commission in Aotearoa | New Zealand is supporting the design of a micro-credential to develop introductory knowledge in this field. Given the complexity and breadth of competencies needed in this role determining the foundational components is challenging. Prior research focused on professional standards and employer requirements only capture one perspective of the role. In this Delphi study, we sought the views of thirty-four learning designers to determine the essential competencies required for learning design in the current (post)pandemic context. Findings demonstrate the importance of understanding the nuances of different modes of learning, pedagogy before technology and the value of relationships.
Lightweight Mapping of Identify Verification Methods and Secondary Course Aspects: “Swiss Cheese” Modelling
Authors: Billingsley William
Published: November 2022

Curriculum mapping in Australia has grown from early notions of constructive alignment to a governed ongoing commitment by institutions to the curriculum structures they have developed. These consider primary aspects of a degree: learning outcomes and how they are achieved. In this paper I describe the need for a descriptive set of mappings for secondary (or quality) aspects of a degree. Notably, mapping the identity verified assessment mechanisms used across a degree can support conversations with accreditors and reviewers around defences against cheating. In 2020 and 2021, many universities were forced to cancel paper-based examinations and academics altered their assessment mechanisms. Mapping the mechanisms that were adopted can reconnect those individual choices with their purpose within the degree. The paper is an experience report from the development of an accreditation submission for a suite of computer science cognate degrees. Other descriptive mappings developed within the submission are also described.
Cats, Coffee, Canberra: Course Design Principles for E-learning
Authors: Wijedasa Vinuri , Contro Pretero Bruna
Published: November 2022

The rapid shift to online and blended modes during the COVID-19 pandemic era resulted in the adoption of digital tools and the development of online resources at an unprecedented scale. However, limitations in time, resources, and learning design or online education experience meant that resources developed were not always fit for purpose or constructively aligned. After designing online modules with teaching staff and students over the past several years, we identified a gap in the knowledge of pedagogical and design principles as they apply to e-learning. This workshop will bridge this gap by providing a step-by-step guide for developing effective e-learning courses. We will explore key considerations and practical strategies and share best practice examples from our own projects. Participants will practice these skills in hands-on activities while storyboarding and designing their own e-learning resource. The workshop is aimed at tertiary educators and developers new to e-learning and those with some experience who wish to upskill in this area.
In the business of connecting: Nudging students
Authors: Gribble Lynn C , Huber Elaine
Published: November 2022

We have long been leveraging the use of technologies to help build and sustain connections in the online environment. The pandemic opened our eyes to the value of these connections and the ability to better use technologies to facilitate them. Now we must question what more we can do. Creating communities through safe environments, building trust, showing students our ‘human’ sides through rapport building and teacher presence which may have previously been hidden in plain sight when operating in a face-to-face mode are a good start. By breaking down traditional barriers brought about through power relationships, the foundations of a quality learning experience are both created and maintained. Using case scenarios and personal narrative from two metropolitan university business schools, we explore techniques that have been used to build connections during lockdowns and begin to reconnect as we emerge from the pandemic. We found that nudging our students through initial uncomfortableness really helped them feel part of a community of learners, one which we also belonged.

The influence of personality traits and basic psychological needs on emotional engagement: An exploration in WeChat discussion
Authors: Xu Bing , Stephens Jason M. , Lee Kerry
Published: November 2022

Online discussion is often adopted to facilitate students’ interaction and communication in higher education. Student engagement, which is a prerequisite of the expected outcomes in online discussion, has been conceptualized as a multi-component construct with behavioural, cognitive and emotional aspects. Compared to the first two aspects, emotional engagement has received the least empirical investigation. Nonetheless, previous research has proposed emotional engagement is related to student’s motivation and personality traits. This study adopted an exploratory approach investigating the associations between students’ basic psychological needs (BPNS, i.e., autonomy, competence and relatedness), personality traits (i.e., the Big Five) and emotional engagement during WeChat-based discussions. Participants included 94 Chinese university students who voluntarily completed an anonymous online survey measuring the aforementioned factors. As hypothesized, results indicated extroversion, agreeableness, openness and BPNS were positively related to emotional engagement in online discussion. Further mediation analyses indicated BPNS had mediation effects on the relationship between traits and engagement. This is a sign for researchers and practitioners that BPNS might be more important for improving emotional engagement in online discussion settings. The practical suggestions for teachers, research limitations and future work are also offered.
‘As long as you use the template’: fostering creativity in a pedagogic model
Authors: Macfarlan Barbara , Hook Josephine
Published: November 2022

As the higher education landscape enters a new era of digital-first education, education designers are tasked with supporting the pedagogic work of educators to design learning experiences which connect students with disciplinary content, with each other and with their educator in the digital learning environment. This paper uses a collaborative autoethnographic approach to reflect upon the challenges experienced by two education designers implementing a pedagogic model to support blended and hybrid learning at scale. A key tension of this work is the perception that design templates diminish educators’ academic freedom and creativity by exerting institutional control over disciplinary experts. We argue that bringing teaching teams together in dialogic and disciplinary learning communities around our pedagogic model fosters creativity by providing space for educators to scaffold their own development, and ultimately, reconceptualise their content for new ways of teaching and learning.
Reconnecting teachers and students: Exploring educator experiences in large online cohorts
Authors: Hammond Kay , Brown Stephen , Murphy Lyn
Published: November 2022

Increasing class sizes in higher education make it difficult to maintain quality. Teaching large cohorts within the context of restrained resources and the limitations of Learning Management Systems impacts the experiences of educators. Research is now examining how educators make sense of this experience to guide stakeholders toward practical directions for future pedagogical and social practices. A review of previous research noted three groups of challenges faced by online teaching: (1) technological, (2) pedagogical, and (3) social. Our study explores the experiences of educators teaching large cohort (500 to 2300 students) undergraduate courses online. This concise paper presents the findings from the social aspects of the challenge. Our qualitative approach explores the experiences of educators at our school who teach large cohorts online. We suggest recommendations to address the social needs of students and educators involved with large cohorts online.
Optimizing the screening of alpha-1 antitrypsin deficiency using serum protein electrophoresis
Authors: Wauthier Loris , Jacques Stéphanie , Delanghe Joris , Favresse Julien
Published: November 2022

Objectives

Alpha-1 antitrypsin (A1AT) deficiency was first identified in patients with emphysema by the absence of the α1 band on serum protein electrophoresis (SPE). Today, capillary zone electrophoresis is widely performed in laboratories. Here, we compared two SPE systems to detect decreased A1AT concentrations to optimize their use as a screening tool for A1AT deficiency.

Methods

Serum protein electrophoresis was performed on 200 samples on the Capillarys 2 and the V8 Nexus. The latter presents two α1 bands (α1 band 1 and 2) while the Capillarys 2 has only one (Capillarys 2 total α1). The measures of A1AT and α1 acid glycoprotein (AAG) were performed as well as the phenotyping of M, S and Z alleles.

Results

At a A1AT cutoff of 0.80 g/L, a cutoff of 1.21 g/L using the V8 Nexus α1 band 2 corresponded to a 100% sensitivity and a 92.4% specificity while a 1.69% cutoff corresponded to a 100% sensitivity and a 92.4% specificity. The performance of the α1 band 1 was suboptimal and rather corresponded to AAG. On the Capillarys 2, a cutoff of 2.0 g/L corresponded to a 75.0% sensitivity and a 86.6% specificity, while a 3.2% cutoff showed a 96.4% sensitivity and a 67.4% specificity. The V8 Nexus α1 band 2 was the method the most correlated with A1AT (r=0.90–0.94).

Conclusions

The V8 Nexus α1 band 2 was the best predictor of A1AT deficiency, probably owing to a better resolution. The use of SPE was however unable to predict each phenotype. Phenotype or genotype studies are therefore still advisable in case of A1AT deficiency.
Pergularia tomentosa coupled with selenium nanoparticles salvaged lead acetate-induced redox imbalance, inflammation, apoptosis, and disruption of neurotransmission in rats’ brain

Published: November 2022

In this study, the neuroprotective potential of either Pergularia tomentosa leaf methanolic extract (PtE) alone or in combination with selenium nanoparticles (SeNPs-PtE) was investigated against lead acetate (PbAc)-induced neurotoxicity. Experimental rats were pretreated with PtE (100 mg/kg) or SeNPs-PtE (0.5 mg/kg) and injected intraperitoneally with PbAc (20 mg/kg) for 2 weeks. Notably, SeNPs-PtE decreased brain Pb accumulation and enhanced the level of dopamine and the activity of AChE compared to the control rats. In addition, elevated neural levels of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and glutathione along with decreased lipid peroxidation levels were noticed in pretreated groups with SeNPs-PtE. Moreover, SeNPs-PtE significantly suppressed neural inflammation, as indicated by lower levels of interleukin-1 beta, interleukin-6, tumor necrosis factor-alpha, nuclear factor-kappa B p65, and nitric oxide in the examined brain tissue. The molecular results also unveiled significant down-regulation in iNOS gene expression in the brains of SeNPs-PtE-treated rats. In addition, SeNPs-PtE administration counteracted the neural loss by increasing B-cell lymphoma 2 (Bcl-2) and brain-derived neurotrophic factor levels as well as decreasing BCL2-associated X protein and caspase-3 levels. To sum up, our data suggest that P. tomentosa extract alone or in combination with SeNPs has great potential in reversing the neural tissue impairment induced by PbAc via its antioxidant, anti-inflammatory, and anti-apoptotic activities. This study might have therapeutic implications in preventing and treating several lead-induced neurological disorders.
Regulatory Competition, Coordination and Polity Convergence in the Covid Ecosystemic Crisis: A Policy Approach
Authors: Garbarino Carlo
Published: November 2022

The paper briefly sketches different “adaptations” possible to address the Covid crisis and then advances three possible avenues for future policy analysis of Covid-related measures, each of these avenues being based on a “conjecture”, respectively an evolutionary, a critical, and a cosmopolitan, and conjecture. The evolutionary conjecture implies regulatory transplants, the critical conjecture elicits competition of Covid-related measures, and the cosmopolitan conjecture assumes coordination of policies. The paper discusses how these conjectures based on pre-Covid literature could explain the regulatory dynamics and then asserts that growing evidence shows that regulatory measures appear to naturally lead to a “polity convergence” based on a common core of “Covid-biopower” and “Covid-biopolitics”. This convergence defies the initial expectations that the fragmented reactions to the Covid crisis could be explained by using the traditional research tools and also poses unprecedented critical issues that demand an expansion of the horizon of policy research.

The Cost of Free Speech: Is Your Personal Data Safe?
Authors: Trakman Leon Esrae
Published: November 2022

This article examines the supremacy accorded to free speech by the First Amendment of the American Constitution and in contrast, the European Union’s 2018 General Data Protection Regulation [GDPR] that highlights data protection. It compares speech as a fundamental human right in US law with the GDPR that champions individual and social rights in personal data as constraints upon speech action. It evaluates US and EU law in light of the history of the law of privacy and the protection of personal information, as is reflected in the International Covenant on Civil and Political Rights [ICCPR]. The article concludes by proposing a uniform and consistent regime for limiting freedom of expression in an era of mass exposure of personal data to harmful online dissemination on the global Internet of Things [IoT].
On the efficiency of a general attack against the MOBS cryptosystem
Authors: Battarbee Christopher , Kahrobaei Delaram , Tailor Dylan , Shahandashti Siamak F.
Published: November 2022

All instances of the semidirect key exchange protocol, a generalisation of the famous Diffie-Hellman key exchange protocol, satisfy the so-called telescoping equality; in some cases, this equality has been used to construct an attack. In this report, we present computational evidence suggesting that an instance of the scheme called “MOBS (matrices over bitstrings)” is an example of a scheme where the telescoping equality has too many solutions to be a practically viable means to conduct an attack.
High sensitivity trace carbon monoxide gas sensor based on endlessly single-mode photonic crystal fiber Sagnac interferometer
Authors: Chen Cui , Huang Xinyue , Feng Wenlin
Published: November 2022

In this paper, a novel carbon monoxide (CO) gas sensor based on α-Fe2O3/MgO is presented and constructed. The endlessly single-mode photonic-crystal fibers (ESPCF) was sandwiched between the four-core fibers (FCF) to form the ESPCF-FCF-ESPCF structure, which was embedded it in the Sagnac loop to construct the Sagnac interferometer. The crystal structure, composition and morphology of α-Fe2O3/MgO sensing film were characterized by the X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electron microscope (SEM), respectively. The results indicated that the α-Fe2O3/MgO sensing film was uniformly coated on the outside surface of two ESPCFs, with a thickness of about 1 μm. When these sensing films adsorbed CO, the monitoring wavelength showed blueshift and the maximum sensitivity was 99.42 pm/ppm. The response time and recovery time were respectively 90 s and 100 s respectively. The Sagnac fiber-optic sensor exhibt high sensitivity, good selectivity and strong stability, and it can effectively realize the monitoring of carbon monoxide.

El nopal duraznillo (Opuntia leucotricha) es utilizado para complementar la alimentación del ganado bovino en pastoreo. El objetivo de esta investigación fue evaluar el valor nutricional del nopal duraznillo fermentado aeróbicamente. Se evaluó el efecto de aditivo (A), chamuscado (CH) y tiempo de fermentación (TF) sobre la densidad celular microbiana total (DCMT) y la calidad nutritiva del nopal fermentado en estado sólido. La mayor DCMT (660.0 millones de células ml-1) se observó en el tratamiento 16 (con A, sin CH y con 24 h de TF). La proteína cruda descendió a partir de las 24 h de TF. Con base en la composición química (PC = 22.7%, FDA = 18.3%, LDA = 3.3%), se considera que el nopal sometido al tratamiento 16 presenta buena calidad nutricional para el ganado. Con respecto a la digestibilidad in vitro, el mayor valor observado (93.8%) se obtuvo con el tratamiento 13 (con A, sin CH y con 0 h de TF).
Análisis deontológico de los anuncios de Navidad de Loterías y Apuestas del Estado
Authors: García Murcia María Patricia
Published: November 2022

La publicidad se reinventa de manera constante para adaptarse a los gustos y necesidades de los diferentes públicos receptores. En los últimos años, existe una tendencia al uso de las emociones y al trato de cuestiones éticas como herramienta publicitaria, es decir, marketing emocional. El consumidor de ahora busca sentirse de algún modo identificado para poder conectar con el anunciante. Es lo que sucede con el caso de los anuncios de Navidad de Loterías y Apuestas del Estado, y por lo tanto, empresa escogida como caso de estudio para este trabajo. La lotería de Navidad se ha convertido en un fenómeno mediático y social, principalmente desde finales de los años 90, con la aparición del conocido “Calvo de la Navidad”. Además, tras la repercusión del spot de 2014, existe un cambio en el eje psicológico de los mismos y de la apuesta publicitaria. En este proyecto se ha realizado un análisis de los anuncios desde 2014 hasta 2019, de Loterías y Apuestas del Estado, con respecto al código ético publicitario de AUTOCONTROL. Para llevar a cabo, de este modo, un estudio enfocado a contrastar las prácticas de los últimos años, desde la perspectiva del código ético más actualizado. Se analizarán los principios deontológicos más incumplidos por Loterías y Apuestas del Estado y la inclusividad social reflejada en los anuncios de Lotería de Navidad. Llegando a conclusiones como el incumplimiento por parte de la entidad de algunos de los artículos recogidos en el código deontológico y la falta de inclusión social en el argumento comunicativo.
comunicación deportiva en los planes de estudio de los grados en periodismo en españa
Authors: Montero Ramos Francisco Javier
Published: November 2022

En tiempos pasados, el periodismo deportivo era contemplado desde la universidad como una especialización menor. El panorama comenzó a cambiar a finales del siglo XX, cuando las facultades fueron incorporándolo a sus programas. Actualmente es una de las áreas de más interés entre los estudiantes de Periodismo, los cuales reclaman una formación específica en la materia. Este artículo analiza la respuesta que ofrecen los grados en Periodismo en España a esa demanda. Para ello, se realiza una investigación exploratoria que describa la presencia del deporte como objeto de estudio en la planificación docente de las universidades. La metodología empleada es el análisis de contenido. Se examinan 38 planes de estudio y 1748 guías docentes de sus asignaturas. Los resultados muestran que el 58 % de las universidades ofrecen una asignatura específica sobre comunicación deportiva, mientras que el 24 % aborda la materia dentro de una disciplina sobre periodismo especializado. Otras asignaturas de campos distintos –principalmente las dedicadas a la radio, el fotoperiodismo, el derecho de la información, la prensa y la televisión– también estudian el deporte de forma puntual. Para el 11 % de universidades esta supone la única forma en la que se aborda la materia, e incluso hay una institución que no incluye referencia alguna al deporte. Por tanto, la mayoría de los grados en Periodismo españoles cubren, en mayor o menor medida, la demanda de formación en comunicación deportiva, aunque los datos indican que esta disciplina aún no está completamente asentada y que tiene margen de desarrollo.
A longitudinal study of incidence and mortality of postpartum hemorrhage at the Gambian tertiary hospital
Authors: Matthew Anyanwu , Sherman Margaret
Published: November 2022

Background: Postpartum Haemorrhage (PPH) is the leading cause of maternal morbidity and mortality in low-income countries, and the primary cause of nearly one quarter of all maternal deaths globally. Women giving birth in low-resource settings are at a higher risk of death than their counterparts in resource-rich settings. Objective: To determine the incidence and mortality of postpartum haemorrhage at the Edward Francis Small Teaching Hospital from January 1st – December 31st 2018. Method: This study was a retrospective, quantitative, hospital-based longitudinal study. The data was collected from the patient’s folders at the obstetrics department with no contact to the patients or caregivers. The patient’s socio-demographic and clinical data was entered into a computer database and analyzed using SPSS software version 24.0. Results: The study revealed that the incidence of PPH was 74.6%. It also shows that the most common cause of PPH was trauma 57 (42.5%). Majority of the deliveries were SVD at 87.3%, referred cases was 78.4%. Mortality due to PPH was 17.5%. Conclusion: The incidence of postpartum haemorrhage was high, trauma the leading cause but mortality showed remarkable decline when compared with previous study.

Objectives: Analysis of success variables of cervical ripening with the Foley catheter in patients with prior cesarean section (PCD), post-term pregnancy (PP), and a Bishop score £6. Evaluation of technique’s safety. Study design: Prospective cohort trial in which 120 patients were enrolled, from April 2014 to May 2018. PCD was codified in four groups: 1) failed Induction (FI); 2) non-progressive labor (NPL) or cephalopelvic disproportion (CPD); 3) abruptio placentae (AP), risk of fetal distress (RFD) or placenta previa; or 4) other causes. Inclusion criteria: singleton pregnancy; >40+6 weeks’ gestation; cephalic presentation; Bishop Score £6; PCD >18 months; signed consent of vaginal delivery (VD). Exclusion criteria: myomectomy with entry into the endometrial cavity; >1 PCDs or uterine rupture; other presentations; macrosomia; multiple pregnancy; placenta or vasa previa; premature rupture of membranes (PROM); inferior genital tract infection. Used material and protocol: Foley catheter insertion at 9 am, followed by 2 hours of fetal cardiotocograph register (CR). This was repeated 6 hours later. Catheter removal 12 hours after the insertion. Intravenous oxytocin was started at 8 am the following day. Statistical analysis: multivariable logistic regression to assess the similarity of populations. Assessment of the relation between VD and APL with the PCD indication and the CL through logistic regressions. The analysis were performed using R (3.5.1), clickR packages (0.3.64), and Boot Validation (0.1.6). Results: A total of 86/109 (78.9%) achieved APL. Whereas 52/86 (60.47%) finished by VD, 34/86 (39.53%) had a cesarean delivery (CD). No significant differences were found between populations. PCD indications for AP, RFD or placenta previa (OR = 7.85 IC95% [1.87, 39], p=0.007) have a higher likelihood of VD. The PCD indication for NPL or CPD; and AP, RFD and placenta previa, have a higher likelihood of achieving APL (OR 14,55 [IC 95% 2.01, 308.5], p=0.023; OR 15,81 [IC 95% 2.03, 359.78], p=0.024; respectively). As CL was higher, the likelihood of APL was lower (OR=0.92 IC95% [0.84, 0.99], p=0.034). No uterine rupture registered. Conclusions: Cervical ripening with the Foley catheter was satisfactory in 78.9% (86/109). PCD indications that are different from FI associate a higher likelihood of VD. CL has a decreasing effect on the likelihood of APL. The Foley catheter is a safe method for cervical ripening.
Gynecological uses of GnRH antagonists: review article
Authors: Carvallo Ruiz Daniel Ernesto , Martínez-Núñez Elizabeth Natalia , Núñez-Troconis José
Published: November 2022

Aim: to review and analyze the use of gonadotropin-releasing hormone (GnRH) antagonists in endometriosis, adenomyosis, non-menstrual pelvic pain, uterine fibroids, prostate cancer, female infertility, and precocious puberty. Methods: the information used to write this manuscript was obtained during a three-month period, between October and May 2022, from specialized literature, written in English and Spanish, related to the use and potential applications of GnRH antagonists in medicine, mainly published during the last five years, using journals found in the most relevant medical digital archives, including PubMed, SciELO, Google Scholar, Cochrane, and Elsevier. Among the keywords used for obtaining this updated information were gonadotropin-releasing hormone (GnRH) antagonists; GnRH receptors (GnRHR); elagolix; relugolix; cetrorelix; linzagolix; hypothalamic-pituitary-gonadal (HPG) axis; endometriosis; adenomyosis; pelvic pain; uterine fibroids; leiomyomas; infertility; precocious puberty; PP; and central PP. Results: GnRH antagonists induce a rapid onset of clinical effects, without the flare-up effect that is seen with agonists, and have immediate therapeutic effects; once treatment concludes, hormonal suppression rapidly ceases, with normalization of gonadal function within a few days, guaranteeing an increase of GnRH concentration, controlling non-menstrual pelvic pain and heavy menstrual bleeding, and serving as part of the treatment of infertility and precocious puberty. Conclusion: even though the aforementioned gynecological pathologies can be treated with the use of multiple drugs, GnRH antagonists have shown to be potential first lines of treatment, as long as their administration protocols are followed correctly.

Introduction: The Coronavirus disease 2019 (COVID-19) vaccine has been approved by the United States Food and Drug Administration as safe and effective against the virus. In addition to the vaccine known adverse effects, a lot of women worldwide have experienced abnormal uterine bleeding (AUB) after receiving the COVID-19 vaccine. This study aimed to figure out the relationship between AUB and the COVID-19 vaccine and to compare the effects of different vaccine types on AUB. Methods: An e-questionnaire-based cross-sectional study conducted between December 2021 to February 2022. The targeted population of the study was all COVID-19 vaccinated female in Saudi Arabia. A total of 1912 respondents participated in the survey, only 1533 were eligible for inclusion in the study. The collected data were analyzed using descriptive statistical methods via Statistical Packages for Social Sciences version 26. Result: Out of 1533 participants, 998 (64.4%) reported AUB in relation to the COVID-19 vaccine. The mean age of the participants was 31.2±8.4 years, and more than half of them (59.4%) were married. Majority had received the Pfizer-BioNTech vaccine in their three shots (77.1%), (78%), and (92.1%), respectively. The incidence of AUB was (82.7%) mainly in form of menorrhagia (38.3%) in the first shot and (88.8%) after the second dose also in the form of menorrhagia (39.1%). Only 3.8% of women had the third dose, the incidence of AUB was 65.8%, mainly in the form of oligomenorrhea (21.1%). Regarding different types of the vaccine in three doses, the Chi-square test (p=0.239), (p=0.200) and Fischer exact test (p=0.265) were statistically significant showing no difference in AUB with different COVID-19 vaccines. Conclusion: The majority of participants had AUB as a result of receiving the COVID-19 vaccine. Furthermore, there was no difference in the incidence of AUB between the Pfizer-BioNTech vaccination and the AstraZeneca Oxford vaccine for the two vaccine types investigated in the study.
Influência da Teologia da Libertação no MST durante as décadas de 1970 e 1980
Authors: Silva Mirian Borges da
Published: November 2022

Em seu surgimento, a Teologia da Libertação (TdL) foi a expressão de um vasto movimento político e social, crítico do capitalismo dependente e da desigualdade social, em que a estratégia de longo alcance seria conseguir uma libertação material que garantisse um desenvolvimento autossustentado e atendesse às reais necessidades da classe trabalhadora. Juntamente na luta anticapitalista, o Movimento dos Trabalhadores Rurais Sem Terra (MST) surge protagonizando a organização pela reforma agrária e pelo socialismo. Nesse sentido, a presente pesquisa buscará analisar a influência ideológica da TdL no surgimento e na prática política de organização do MST, durante as décadas de 1970 e 1980, a partir da análise documental do material disponibilizado pelo MST e pelo Centro de Documentação “Dom Tomás Balduino”.
Análisis de datos acelerográficos de Costa Rica para la generación de modelos de atenuación: periodo 1998 a 2021

Published: November 2022

Los modelos de atenuación de las ondas sísmicas se obtienen a partir de datos aceleográficos y representan uno de los insumos más importantes para los estudios de amenaza sísmica, la cual es fundamental para el diseño de estructuras y sistemas sismorresistentes cada vez más eficientes. En vista de que el registro de nuevos sismos aporta información sumamente valiosa para actualizar dichos modelos y estudios, es necesario que ambos se revisen y se replanteen con cierta periodicidad. En este trabajo se desarrolla un análisis descriptivo de datos acelerográficos registrados en estaciones de Costa Rica hasta el año 2021, como base para el posterior desarrollo de modelos de atenuación para el país. La investigación está motivada por el gran número de datos acelerográficos registrados en los últimos 11 años, gracias a la densificación de la red de instrumentos que administra el Laboratorio de Ingeniería Sísmica de la Universidad de Costa Rica. Esto hace que, en el momento actual, se disponga de una base de datos acelerográficos suficientemente amplia y robusta, para poder generar ecuaciones de predicción del movimiento fuerte, conocidas como GMPEs (del inglés Ground motion prediction equations) que representen la atenuación en los tres regímenes tectónicos presentes en el país: cortical, subducción interfase y subducción intraplaca. En esta etapa de la investigación se analizan un total de 3192 registros asociados a 245 sismos, obtenidos después de aplicar una serie de filtros de selección sobre una base de datos compuesta inicialmente por 3981 registros. El análisis ha consistido en obtener las distribuciones del número de eventos y del número de registros en función de la magnitud, profundidad, régimen tectónico y tipo de suelo en la estación de registro, clasificando éste siguiendo los criterios del Código Sísmico de Costa Rica (CFIA, 2010). Entre los principales resultados de esta investigación, que condicionarán los rangos de aplicabilidad de los modelos que se desarrollen posteriormente, se destacan (1) la identificación de una escasez de registros en condiciones de suelo duro o roca (S1), así como de magnitudes altas a distancias hipocentrales cortas y de magnitudes bajas a distancias largas.; (2) el rango de distancias hipocentrales de los registros disponibles es (5-300 km) para sismos corticales, (15-300 km) para subducción interfase y (40-400 km) para subducción intraplaca. Finalmente, se estimaron dos medidas de distancia para fuentes extendidas, denominadas de ruptura, R RUP, y de Joyner y Boore, R J&B, empleadas cuando la ruptura no puede considerarse como puntual. Dichas distancias se han calculado a partir de las distancias para fuentes puntuales, epicentral e hipocentral, R EPI e R HYPO respectivamente, siguiendo la metodología propuesta por Thompson y Worden (2018).
Konceptualizacja „powinnego” ładu socjo-politycznego w państwach zachodnich w dobie XIX-wiecznych przemian w myśli krakowskiego konserwatysty Henryka Lisickiego

The article presents the views of the representative of Krakow conservative – Henryk Lisicki on the subject of nineteenth-century socio-political changes in Western Europe. His reflections focused on the search for stability of the internal order of those countries, conducted from a moderately conservative position. This meant criticizing the extreme models of socio-political orders that he believed the experience of personal monarchs, an egalitarian republic or authoritarian military dictatorships had brought. In the context of his reflections, the "should" political model was the constitutional monarchy, ensuring the balance of society (even within a strongly diversified one, under the influence of contemporary economic changes), guarantees of civil rights as well as centers of power: the monarch and the representation of the general public, i.e. parliament.

Historical consciousness is a phenomenon of incorporating the past into the current social consciousness, being the sum of ideas about the past and the way of thinking about it; it also entails awareness of the existence of the past, present and future and a sense of having one's own, unique history, attributed to any given society. This study presents the results of research analyzing the respondents’ historical awareness of such historical events of the last century, which are considered the most important for Polish history and have particularly stuck with their consciousness. The research shows that the respondents’ historical consciousness is on a rather low level, and the choices of the events from Poland’s past are conditioned by the media campaign connected with the anniversary of Poland regaining independence in 1918.
Nawyki komunikacyjne cyfrowych odbiorczyń zamieszkujących mniejsze miejscowości. Przyczynek do badań historyczno-medioznawczych

The aim of the article is to present the results of research conducted in 2019 and 2020 to answer the question of how, with what intensity and under what circumstances the perception of media content by digital natives living in smaller towns occurs. The analysis shows that the assumed hypotheses regarding the growing role of social media and internet sources have been confirmed. Importantly, in the opinion of the respondents, also the traditional media, i.e. radio and television, are a valuable source of information and entertainment for women whose opportunities to participate in culture are limited by their chosen place of residence. The analyzed data also shows that traditional linear television, sometimes referred to as programmed television, is being replaced by streaming services, although, as the respondents point out, the most convenient receiving device is still a television set. The results of radio listenership are also similar to the national results. A small percentage of readers of the daily press and magazines is also a nationwide trend, especially in the studied demographic, although attachment to reading the press during trips or holidays is an interesting phenomenon that is currently the object of in-depth description in the extended research conducted by the author. The presented data are preliminary studies necessary to expand and discuss future methods and goals.
Collective trust and stress at work. Evidence from the banking sector
Authors: Kaźmierczyk Jerzy
Published: November 2022

An increasing collective trust reduces stress at work in many countries, regardless of national characteristics. The goal of this paper was to investigate whether collective trust is related to occupational stress among bank employees, where 2,279 bank employees were surveyed. Exploratory factor analysis was used to build a collective trust index based on: openness, care, appreciation, common values, honesty/fairness, loyalty, dyadic trust (a direct question about trust), and job security. Cronbach’s alpha allowed to evaluate the quality of the obtained index. The regression then pointed to those aspects of collective trust and metric variables which were relevant to the level of occupational stress. The most important factors which correlate with stress at work were job security, common values and affective commitment. The authors managed to create a stress management model based on collective trust and components of the metrics.
Does a trade surplus raise the exchange rate exposure? A perspective on Sino-US relations
Authors: Su Chi-Wei , Tao Ran , Umar Muhammad , Huang Shi-wen
Published: November 2022

This research examines dynamic causality between trade surplus (TS) and exchange rate exposure (ERE), utilizing the bootstrap sub-sample rolling window test. The empirical findings indicate that there is the time-varying bidirectional causality in TS and ERE within certain sub-periods. Specifically, ERE manifests both positive and negative influences on TS. In turn, TS has a positive effect on ERE which proves the export-oriented model proposed by Bodnar et al. (2002). Furthermore, due to the complex changes in Sino-US trade policies during the trade war, ERE is still stimulated under the overall downward trend of TS. This means that the widening TS can inevitably increase ERE, which may cause more trade frictions with the US. By studying the time-varying relation between these two variables, investors can reasonably allocate assets according to the changes of TS and avoid losses caused by market panic. Policy-makers could restrict the abnormal flow of international capital and promote multilateral trade cooperation, especially in times of structural economic change, to reduce trade friction and maintain a relatively stable ERE level.
