Published: November 2023

We discussed the process of expansion and democratization at the State University of Mato Grosso - Unemat from the perspective of participatory democracy in Santos (2002).What policies and expansion programs implemented by the IES that contribute to the democratization of access? What is the profile of the Unemat participant? We use the case study as a methodology. We analyzed documents about the trajectory of the IES; we identified Programs and actions for access and we profiled the participants in the period from 2005 to 2011, from the database ENGRESSANTES. The results show that access is being thought of at Unemat, only in terms of the size of the entrance; it can therefore be considered as being democratized, as the IES serves traditional communities and students, most of them from public schools, blacks (colored or black), low income, the unemployed and unmarried. However, we reaffirm the incompleteness in the analyzes on the democratization of higher education only by the dimension of entry, since we understand access in interdependence, entry, permanence, completion and quality teaching.
INTERVENÇÃO POLICIAL E JUDICIALIZAÇÃO DOS ATOS VIOLENTOS NA ESCOLA
Authors: Silva Fabrine Leonard
Published: November 2023

Neste estudo, investigamos os atos infracionais e os delitos que acontecem no interior das escolas em Belo Horizonte. Em Belo Horizonte, o estudo dos atos infracionais foi realizado a partir da seleção de 582 processos judiciais originados dos atos infracionais cometidos por adolescentes, no interior de escolas municipais e estaduais da capital mineira, entre os anos de 2014 e 2015. O trabalho de campo e o contato com os muitos documentos que constituíam os arquivos dos processos judiciais, a partir dos atos infracionais cometidos por adolescentes nas escolas, possibilitaram a identificação dos papéis desempenhados pelos policiais e pelos agentes judiciários nos procedimentos para apuração do evento infracional e para a aplicação, ou não, de medidas socioeducativas e/ou protetivas aos autores dos atos infracionais. Realizamos uma análise documental desses processos seguindo as sugestões de André Cellard (2008), o qual mostra as técnicas utilizadas para realizar o manuseio de documentos, a saber: descrever como o documento se organiza; classificar os documentos; e criar categorias. O documento de maior importância encontrado no interior dos processos foi o Boletim de Ocorrência. Por meio dele, aferimos que, um policial, ao responder um chamado da escola, leva consigo uma lente própria e construída na sua formação – sob a responsabilidade da Secretaria Nacional de Segurança Pública, à época, subordinada ao Ministério da Justiça. Os procedimentos inquisitórios utilizados pela Polícia Militar ao longo do processo judicial pelo qual passa o(a) adolescente giram em torno da necessidade de se chegar à constatação da prova, já que ela é a “alma do processo” (SENASP, 2019).
Implications of the existence of opposition political parties as checks and balances in the implementation of democracy
Authors: Fahruddiana Yosphia
Published: November 2023

The opposition plays an important role in monitoring government policies and programs or in fulfilling checks and balances. However, the opposition parties in parliament have always been in the minority along the long road of Indonesian populist democracy. This situation weakens the control function and widens the gap to uphold the will of the people. There are opposition parties which have always been a minority group in parliament which is even worse if the decision-making cannot be resolved by a joint decision. If this happens, the minority opposition forces cannot influence government policies. Consequently, when the votes of the parties in a coalition supporting the government have dominance in determining public policies, this will result in policies that are usually authoritarian in nature.

Published: November 2023

El elevado consumo de medicamentos por parte de la población relacionada con un deficiente sistema de eliminación de medicamentos vencidos o en desuso en los hogares trae como consecuencia que sean vertidos con los residuos domésticos o a través del desagüe contaminando el agua y el suelo. En Perú, no existe legislación específica que conlleve a una disposición final de los desechos de medicamentos, incrementando los problemas ambientales. Así mismo, el consumo excesivo y la degradación de los recursos naturales trae como consecuencia la contaminación del medio ambiente, por lo que el ámbito educativo pretende con la educación ambiental concientizar al estudiante. El estudio tuvo por objetivo determinar la. relación entre la disposición final de residuos farmacéuticos y la actitud ambiental. El estudio con enfoque cuantitativo, tipo aplicado, nivel descriptivo-correlacional de diseño no experimental, de corte transversal, con base en un muestreo no probabilístico por conveniencia, participaron 212 estudiantes de Educación Superior No Universitario. Los resultados obtenidos demuestran una relación directa entre la disposición final de residuos farmacéuticos y la actitud ambiental, pudiéndose generalizar que existe correlación directa entre las prácticas de disposición final de residuos farmacéuticos y las dimensiones cognitiva y conductual de la actitud ambiental; mientras que las prácticas de disposición final de residuos farmacéuticos y la dimensión afectiva de la actitud ambiental demuestran correlación inversa. En base a los resultados obtenidos, se puede comprobar que, a mayor conocimiento de disposición final de residuos farmacéuticos mayor actitud ambiental.

Authors: De Montmollin Maria , Bétrisey Sylvain , Feller Martin , Moutzouri Elisavet , Blum Manuel R. , Amsler Jennifer , Papazoglou Dimitrios D. , Möller Burkhard , Rodondi Nicolas
Published: November 2023

BACKGROUND AND AIMS: People with familial hypercholesterolaemia are 13 times more likely to develop cardiovascular disease than the general population. However, familial hypercholesterolaemia remains largely underdiagnosed. Tendon xanthoma is a specific clinical feature of familial hypercholesterolaemia and its presence alone implies a probable diagnosis of familial hypercholesterolaemia according to the Dutch Lipid Clinic Network Score (DLCNS). The aim of the study was to determine whether ultrasound detects more Achilles tendon xanthomas (ATX) than clinical examination.
METHODS: We recruited 100 consecutive patients with LDL-C ≥4 mmol/l. Achilles tendons were evaluated through clinical examination by trained physicians and sonographic examination by another physician blind to the results of clinical examination. Blind second readings of ultrasound images were performed by an expert in musculoskeletal ultrasound. We compared the proportion of patients with ATX detected by either clinical examination or ultrasound and the proportion of patients with a probable/definite familial hypercholesterolaemia diagnosis on the DLCNS before and after ultrasound.
RESULTS: Mean (SD) age was 47 (12) years; mean highest LDL-C was 6.57 mmol/l (2.2). ATX were detected in 23% of patients by clinical examination and in 60% by ultrasound. In consequence, 43% had a probable/definite diagnosis of familial hypercholesterolaemia on the DLCNS using clinical examination compared with 72% when ultrasound was used.
CONCLUSION: Compared to clinical examination, ultrasound examination of the Achilles tendon substantially improves the detection of ATX and may help to better identify patients with familial hypercholesterolaemia who are at high risk for premature cardiovascular disease.
Bullying Behavior, Mediating Role of Employee Silence and their Effects on Organisational Citizenship Behavior: Evidence from Seven Iranian Metropolises
Authors: Saghih Amir Mohammad Fakoor , Ilani Reyhane
Published: November 2023

Depending on dominant organisational conditions, various factors may affect the service quality and employees' willingness to behave positively. Therefore, this study investigated the effects of bullying behaviour on organisational citizenship behaviour (OCB) through employee silence. This is an applied-descriptive survey consisting of drivers (1820 in total) of private bus companies in seven Iranian metropolises. The statistical population was selected through simple random sampling. After that, questionnaires were distributed, and the collected data were analysed through structural equation modelling (SEM) in SPSS and AMOS. The results revealed the effect of bullying behaviour on employee silence and OCB. Moreover, bullying behaviour had a negative effect on OCB with the mediating role of employee silence. The analysis of employee silence can provide opportunities to prevent negative behaviours in the workplace. Since there is scant research literature on the role of employee silence in the relationship between bullying behaviour and OCB, addressing this issue can help to fill the existing research gap.
Implications of Foreign Language Use for Creative Self-evaluation Bias and Creative Performance
Authors: Loderer Anja , Muehlfeld Katrin , Wilken Robert
Published: November 2023

Creative self-evaluations are important determinants of future creativity. Despite extensive research that identifies antecedents of individual creativity, little is known about what determines individuals’ biases in self-assessing their own creative performance. In particular, we do not know how contextual factors may influence individual creative self-evaluations. As workplaces become increasingly multilingual in the wake of globalisation, the language in which work is being performed has become one of these factors. In an experiment with working professionals (N = 86), we assessed actual creative performance using established creativity (specifically, idea generation) tasks. Participants worked on these tasks in either their native or a foreign language and were asked to self-evaluate their creative performance afterwards. Results show that creative self-evaluations generally deviate from actual performance, such that high (low) performers tend to underestimate (overestimate) their creative performance. While actual creative performance is lower when using a foreign language, the creative self-evaluation bias tends to be higher in a foreign compared to a native language setting. Further, we find tentative evidence that individuals who work in a foreign language and who are highly proficient in this language may be less biased in their creative self-evaluations. Unlike proficiency, foreign language anxiety does not appear to affect this bias.

Published: November 2023

Minimally invasive surgeries continue to advance at an immensely fast pace, moving from open discectomy surgeries to microscopic ones using tubular systems, to do fusions, to correct deformities, until we reached a place where we are tackling most spinal pathologies in a minimally invasive fashion, For many spine surgeons, the field of spine endoscopy, whether uniportal or biportal, is still unexplored, to some extent due to their mastery in open and microscopic techniques, and to another extent the learning curve that it takes to master endoscopic spine, as well as a lack in well-structured clearcut data regarding its indications and limitations, and this chapter will hopefully shed the proper lighting on the field of spinal endoscopy, making surgeons understand its utility in treating different pathologies, discussing the research and data comparing spinal endoscopy with more traditional techniques, as well as understanding endoscopic spine surgery’s learning curve, and how to overcome the timeline in mastering its basic techniques.
Theory for Anxiety Disorders
Authors: Garza-Ulloa Jorge
Published: November 2023

“Anxiety” is part of our lives and is frequently generated by unhandled stress, but people with “anxiety disorders” have repetitive episodes of excessive “anguish” and “anxiety” that interfere with their daily activities. At the present time, the causes of “anxiety disorders” are not fully understood as diseases, where doctors can diagnose or evaluate the level of diseases using mainly medical lab tests or biomedical imaging, identifying the cause as infection, inflammation, or other physical factors that can be treated with medication or surgery or even prevented by vaccines. Based on the logical assertion that “in order for something to be improved, it must be understood and measured”. The objective of the “theory of anxiety disorder” is to understand it and identify body parameters that can be measured in a “subjective mode”, and I recommend some new experimental “objective mode”, to detect the degree of physical altered symptoms and mental abnormal reactions classified as “anxiety disorder”, which is characterized by a consistent sense of feeling pressured and overwhelmed. The steps to understanding the process by which “anxiety” is generated and how it could be analyzed and measured as evolving into “anxiety disorder”.
Interactions between the Oldest and the Youngest Age Groups in the Current Multigenerational Organizations: The Case of Slovakia
Authors: Šestáková Monika
Published: November 2023

The present chapter analyzes the interactions and outlines a potential cooperation between the two age groups, usually regarded as extreme sides of the intergenerational spectrum. The oldest group (seniors) includes working people in the age 65+. The youngest group are adults in the age 18–30. Specific generational features of both age groups in Slovakia are characterized and compared with those of their peers in other developed countries. The basic objective of the paper is to show that irrespective of the significant generational differences, the two generations need not be in a conflict. They can be even intrinsically motivated to cooperate. This cooperation can be based on a combination of the younger generation’s energy, digital skills and sense for social and ecological progress with the working experience, patience, understanding of the character of socioeconomic changes and loyalty to employer organizations, typical of seniors. The last part of the chapter is devoted to intergenerational interactions in universities’ environment and tasks of universities in educating graduates corresponding to the labor market requirements.
The platelet serotonergic system and the search for new biomarkers and therapeutic options for diverse diseases
Authors: Briones-Aranda Alfredo , Corzo-Gómez Josselin , Casique-Aguirre Diana , Megchún-Hernández Mauricio
Published: November 2023

The latest advances in basic and clinical research on the main components of the platelet serotonergic system are presently reviewed. These components consist of serotonin (5-HT), enzymes that participate in 5-HT metabolism, the serotonin transporter (SERT), and 5-HT1A, 5-HT2A, 5-HT3, and 5-HT4 receptors (each with their corresponding mechanism of intracellular transduction). An additional focus is on related biomarkers or drugs for the diagnosis or treatment of the pathophysiology of diverse disorders such as depression, anxiety, hemorrhagic dengue, coagulopathy generated by COVID-19, myocardial infarction, and preeclampsia. The drugs analyzed include serotonin reuptake inhibitors and serotonergic drugs that act on 5-HT receptors. Through the platelet serotonergic system, serotonergic drugs not only interact with the central nervous system but also may participate in coagulation, vascular permeability, and peripheral vascular resistance, which has many implications. Finally, perspectives are offered for future research on biomarkers and new therapeutic targets.

Published: November 2023

Background: Cognitive development during childhood has significant implications for an individual's cognitive functioning throughout life. Perinatal and postnatal factors may influence this function. Objectives: In this study, we aimed to investigate the relationship between perinatal and postnatal factors and cognitive development in healthy toddlers aged 18 – 22 months. Methods: In this retrospective cross-sectional study, we examined 50 toddlers born between March 2015 and March 2016 at a teaching hospital in Zahedan, Iran. This study focused on perinatal and neonatal risk factors based on the results of the Bayley-3 test. Data were analyzed using Mann–Whitney U, Kruskal–Wallis, and Pearson correlation coefficient tests. Results: Analysis revealed significant correlations between several perinatal factors and subsequent cognitive performance in toddlers. Greater maternal chronological age at the time of parturition, higher levels of mother's attained education, increased neonatal weight at delivery, augmented body weight in the toddler phase, as well as the documented occurrence of neonatal hyperbilirubinemia within the initial postpartum period, demonstrated meaningful associations with enhanced cognitive functioning as assessed during the toddler stage of development. Conclusions: Based on the results, it is advised that pregnancy commences at a maternal age that circumvents risks of very young childbearing. Offspring growth should be closely tracked, and neonatal jaundice promptly treated, as these perinatal factors impact cognitive performance. Giving priority to these factors improves a child's chances of healthy cognitive development, which is essential for success in life.
Social media use does not increase individual-based relative deprivation: Evidence from a five-year RI-CLPM
Authors: Lilly Kieren , Sibley Chris , Osborne Danny
Published: November 2023

Although a growing literature demonstrates that social media usage fosters upward social comparisons, the potential for social media use to elicit perceptions of unjust disadvantage relative to others remains unexplored. We address this oversight by leveraging six annual waves of a nationwide random probability sample of adults (ages 18–99; N = 62,017) to examine the average between- and within-person associations between social media use and feelings of individual-based relative deprivation (IRD) over time. Results from our preregistered analyses revealed that those who are high social media users across time tend to also experience higher levels of IRD. After adjusting for these stable between-person differences, within-person changes in social media use failed to predict changes in IRD over time (or vice versa). Subsequent exploratory analyses replicated these results across different age- and gender-based subgroups. Our results relieve concerns that social media use fosters long-term perceptions of disadvantage over time within individuals and suggest that concerns over the long-term detrimental effects of social media use on social comparison processes may be unfounded. These results also highlight the need to separate between-person stability from within-person change when investigating temporal precedence in longitudinal research.
Towards mapping the gaps in Alaska
Authors: Zimmermann Mark , Prescott Megan M.
Published: November 2023

In 2018, the General Bathymetric Chart of the Oceans (GEBCO) announced the Nippon Foundation-GEBCO Seabed 2030 Project to improve further the GEBCO map of the world’s oceans. The United States (U.S.) has responded with different initiatives to complete a map of its Exclusive Economic Zone (EEZ). With Alaska accounting for the greatest fraction of the U.S. EEZ, here we provide an analysis showing which portions of the National Oceanic and Atmospheric Administration’s, National Marine Fisheries Service, Alaska Fisheries Science Center (AFSC) bathymetry maps are supported by actual observations. Data support of raster cells ranged from 2.4 % to 43.4 % within six previously published AFSC bathymetry compilations, with high variability by depth and supporting hydrographic data type. This will guide new Alaska mapping efforts towards the gaps and away from remapping areas, increasing progress in fulfilling the goals of Seabed 2030 Project.

Published: November 2023

Vertical quality evaluation in hydrographic surveys, particularly utilizing Multibeam Echosounders (MBES), presents challenges due to limited bathymetric information in obtaining homologous points and the absence of robust statistical criteria in depth estimation. This study addresses these challenges by proposing and validating the Point-to-Point (P2P) method, which prevents geostatistical interpolation while enhancing accuracy using a limited distance to search for the nearest neighbor and to find a probable homologous point. Three distinct methods were applied to compare depths of sounding lines and check line, namely Surface-to-Surface, Surface-to-Point, and Point-to-Point. The efficacy of the P2P method was established through a comprehensive evaluation of RMSE and ϕRobust, besides the discrepancies. This research underscores the significance of the P2P method, showcasing its superiority over conventional approaches and its potential to rectify the absence of statistical rigor in vertical quality assessment.

Published: November 2023

Worldwide, flooding caused by the overflow of rivers is a real threat to people and their property. This is why it is so important to have high-quality data and indicators for modelling this phenomenon. The aim of this study is to determine the morphometric characteristics involved in the flooding process in the Bia watershed upstream Aboisso outlet, and to estimate flood flows statistics both in order to get some insight in the overall features of the river watershed and flood behaviour. To do this, the methodological approach adopted initially enables the morphometric parameters of Bia watershed upstream Aboisso to be determined using empirical formulae and a DTM. Secondly, a frequency analysis is carried out, based on sampling the maximum annual flows generated from the series of average daily flows (1950–1983) from Aboisso station. Various probability laws for extreme values (Gumbel, Weibull and VEG) were fitted to the sample. The results show that the Bia watershed upstream Aboisso outlet covers an area of 8,887 km2, is elongated in shape (KG: 3.58), a low relief (DS: 16.05) and a　moderate average slope (IW) estimated at 14.67 %. In addition, the stream which is draining　the basin is more than 300 km long, with an average longitudinal slope (I) of 9.6 %. Estimated flood quantiles for return periods T5 , T10, T20 and T50 are 368 m3/s, 446 m3/s, 520 m3/s, 616 m3/s and 688 m3/s respectively.

A human-in-the-loop system for labeling knowledge components in Japanese mathematics exercises
Authors: Flanagan Brendan , Tian Zejie , Yamauchi Taisei , Dai Yiling , Ogata Hiroaki
Published: November 2023

Many modern learning systems rely on a data representation of the knowledge that is to be learned to estimate a learner’s mastery state and recommend appropriate learning tasks to further improve their acquisition of knowledge and skills. In particular, the rapid development of intelligent tutoring systems (ITS) and standardized curricula has increased the need for information on knowledge structures and their links to learning materials and tasks. However, manually labeling educational data has traditionally been a time-consuming, labor-intensive task, and thus has limited its use by time-constrained teachers and practitioners. In previous research, a range of machine-learning methods have been proposed to address this problem, with only a few of them focusing on Japanese educational datasets from secondary schools. In this paper, to support the labeling of Japanese mathematics exercises by teachers and other domain experts, we apply natural language processing techniques including word-embedding and key-phrase-based exercise-to-exercise similarity methods. We evaluated the proposed method by both the performance of the models when compared to several state-of-the-art methods, and also its effectiveness in supporting humans in the task of labeling educational materials. Through this two-phase evaluation, we found that the proposed method outperformed other methods, and when implemented in a human-in-the-loop system it achieved significantly more accuracy and consumed less time for the task of labeling mathematics exercises.

This research involved one class as an experimental class to determine the effectiveness of the Prototype Curriculum Policy in Mathematics Learning at SMP Negeri 2 Kajen, Pekalongan Regency. The research design used was a group pretest-posttest design. The main problem in this research is whether the prototype curriculum policy is effectively implemented in mathematics learning for class VII students at SMP Negeri 2 Kajen. This type of research is pre-experimental research. The research results show that: (1) The average score of students' mathematics learning outcomes before the prototype curriculum was implemented in mathematics learning was 22.8 and was deficient. These results showed that 25 students, or 100%, had yet to reach the KKM, which meant that classical completion had not been achieved. (2) The average score of students' mathematics learning outcomes after implementing the mathematics learning prototype curriculum is 85 and is in the high category. These results found that 24 out of 25 students, or 96% achieved the KKM, which means that classical completion was achieved. (3) The average percentage of student activity is 83%, if it is linked to the student activity criteria, namely 75%, then student activity reaches the active criteria. (4) The student response questionnaire showed that 97% responded positively to mathematics learning. From the research results above, it is concluded that the prototype curriculum policy for mathematics learning is effectively implemented at SMP Negeri 2 Kajen, Pekalongan Regency

Published: November 2023

Objectives: The use of herbal products/dietary supplements (HP/DS) in the pediatric population is increasing day by day. The interaction of HP/DSs with drugs with a narrow therapeutic index such as phenytoin, phenobarbital, and valproic acid, may cause problems in treatment. In this respect, it is very important to determine the use of HP/DS in children with neurological diseases and/or complaints. In this study, it was aimed to determine the use of HP/DS and the factors affecting the use of these products in individuals with a neurological complaint and/or disease who applied to the pediatric neurology outpatient clinic.
Methods: Parents were questioned face-to-face as part of the descriptive questionnaire research. 174 questionnaires with appropriate data quality were included in the study. The statistical software tool SPSS 23.0 was used to analyze the data.
Results: 44.6% of the parents stated that they gave HP/DS to their children. The findings of the analysis showed that kids whose parents use HP/DS are more likely to utilize these items themselves (p<0.001). The most commonly used products are linden (70.1%), bee products (26.0%), carob (18.2%), chamomile (13.0%), and lemon (13.0%).  It has been determined that the reasons for parents to have their children use HP/DS are to strengthen the immune system (51.9%), improve general health status (40.3%), and supplement normal nutrition (27.3%), respectively.
Conclusions: This study revealed a high frequency of HP/DS use in children with pediatric neurological diseases/complaints in Türkiye. The frequency of HP/DS use was higher in children whose parents tended to consume HP/DS. Considering the high use of these products, healthcare professionals need to inform parents to prevent adverse effects caused by HP/DS.

A criança, por ser sonhadora e livre, está aberta a novas experiências e possibilidades. Ela é capaz de se encantar com o mundo ao seu redor.
Educação, infância e imaginação
Authors: Simonis Richter Sandra Regina , Montiel Severo Trindade Talula
Published: November 2023

O ensaio aproxima educação, artes e infâncias, particularmente a literatura, para afirmar a experiência das crianças começarem-se em linguagem como início radical de gestos e palavras que promovem a apropriação de si e do mundo. A abordagem filosófica contribui para argumentar a experiência poética de linguagem como infância do pensamento que emerge da inseparabilidade entre corpo sensível e mundo no ato de aprender a interrogar e valorar o vivido ao transformá-lo em relatos e narrativas que nos situam no mundo. Diante da hegemonia de um realismo que nega a ação de narrar como algo intrínseco às infâncias, e a imaginação do mundo como evento linguageiro coletivo, destaca o direito das crianças à ficção em sua função de densificar o vivido ao abrir e promover outras dimensões de realidade no ato de redescrevê-lo.
Imagens da Infância: O que docentes podem aprender a partir dos saberes compartilhados pelas crianças?
Authors: Ferreira de Castilho Flávia , Mont'Alverne Braun Chaves Iduína
Published: November 2023

O objetivo deste trabalho é apresentar um excerto da tese de doutorado que buscou a compreender os sentidos da Educação Infantil, refletindo não só sobre como formamos as crianças, mas como estas podem provocar alterações no fazer docente. Neste sentido, apenas a narrativa de uma criança será apresentada. Os fundamentos teórico-metodológicos adotados se basearam na Antropologia da Complexidade de Edgar Morin, a Antropologia do Imaginário de Gilbert Durand, a Sociologia do Cotidiano de Michel Maffesoli e a Filosofia da Imaginação Poética e Criativa de Gaston Bachelard. Também contribuíram como base teórica os estudos sobre infância e os contributos da Pesquisa Narrativa proposta por Clandinin e Conelly, Passeggi e Chaves, dentre outros. Através da hermenêutica simbólica, identificou-se as imagens, evidenciando seu potencial significativo em cada uma das experiências compartilhadas ao longo dos encontros com os sujeitos da pesquisa. Contar o próprio percurso é uma experiência que atiça a memória e ressignifica o vivido. O conto de Bela, uma criança de seis anos, aqui apresentado, mostra o potencial formativo da narrativa.
Risk Factors for Hemoptysis in Ethiopia: A Hospital Based and Case-Control Study
Authors: Ingbar Corey
Published: November 2023

Introduction: Hemoptysis, the expectoration of blood from the lower respiratory tract, is a prevalent symptom with diverse etiologies. While global data on risk factors exists, information specific to the Ethiopian context is limited. This study aimed to identify risk factors associated with hemoptysis in Ethiopia.
Methods: A hospital-based case-control study was conducted at three tertiary hospitals in Addis Ababa, Ethiopia, from January 2022 to December 2022. Cases were patients aged ≥18 years presenting with hemoptysis. Controls were age- and sex-matched individuals attending the same hospitals for non-respiratory conditions. Data were collected using a structured questionnaire and medical record review. Logistic regression was used to identify independent risk factors.
Results: A total of 400 participants (200 cases and 200 controls) were included. The mean age was 42.5 years (SD ± 15.2). Independent risk factors for hemoptysis included: previous history of tuberculosis (adjusted odds ratio [AOR] = 4.8, 95% CI 2.9-7.9), current smoking (AOR = 3.2, 95% CI 1.8-5.7), biomass fuel exposure (AOR = 2.5, 95% CI 1.4-4.5), and history of chronic obstructive pulmonary disease (COPD) (AOR = 2.1, 95% CI 1.2-3.7). HIV infection was not independently associated with hemoptysis in this study (AOR = 1.3, 95% CI 0.7-2.4).
Conclusion: This study identified previous tuberculosis, smoking, biomass fuel exposure, and COPD as independent risk factors for hemoptysis in Ethiopia. These findings highlight the need for targeted public health interventions, including smoking cessation programs, improved indoor air quality, and early detection and management of tuberculosis and COPD, to reduce the burden of hemoptysis in Ethiopia.
Sterically stabilized cyclopropenylidenes. An example of Octopus publishing?
Authors: Rzepa Henry
Published: November 2023

Whilst I was discussing the future of scientific publication in the last post, a debate was happening behind the scenes regarding the small molecule cyclopropenylidene. This is the smallest known molecule displaying π-aromaticity, but its high reactivity means that it is unlikely to be isolated in the condensed phase.
Tetra-isopropylmethane and tetra-t-butylmethane.

Published: November 2023

The homologous hydrocarbon series R  4  C is known for R=Me as neopentane and for R=Et as 3,3-diethylpentane. The next homologue, R=   i   Pr bis(3,3-isopropyl)-2,4-dimethylpentane is also a known molecule[1] for which a crystal structure has been reported (DOI: https://doi.org/10.5517/cc4wvnh). The final member of the series, R=  t  butyl is unknown.
The Stevens rearrangement: how history gives us new insights.
Authors: Rzepa Henry
Published: November 2023

In a recent post, I told the story of how in the early 1960s, Robert Woodward had encountered an unexpected stereochemical outcome to the reaction of a hexatriene, part of his grand synthesis of vitamin B12. He had constructed a model of the reaction he wanted to undertake, perhaps with the help of a physical model, concluding that the most favourable of the two he had built was not matched by the actual outcome of the reaction.
Molecules with very large dipole moments: cyclopropenium acetylide

Occasionally, someone comments about an old post here, asking a question. Such was the case here, when a question about the dipole moment of cyclopropenylidene arose. It turned out to be 3.5D, but this question sparked a thought about the related molecule below.
The thermal reactions … took precisely the opposite stereochemical course to that which we had predicted
Authors: Rzepa Henry
Published: November 2023

The quote of the post title comes from R. B. Woodward explaining the genesis of the discovery of what are now known as the Woodward-Hoffmann rules for pericyclic reactions.[1] I first wrote about this in 2012, noting that “  for (that) blog, I do not want to investigate the transition states”.  Here I take a closer look at this aspect. I will start by explaining my then reluctance to discuss transition states.
MetaNook2014 – Command Line Talk

Published: November 2023

Last night was the night of this year’s MetaNook. It was the fourth time that the local hackers, most notably MetaMeute and Chaotikum, joined forces to organize a night full of beginner-friendly introductions, advanced tech talks, and project presentations. My talk contribution this year was a brief introduction in the “magic” of the command-line.
An interesting aromatic molecule found in Titan’s atmosphere: Cyclopropenylidene
Authors: Rzepa Henry
Published: November 2023

Cyclopropenylidene must be the smallest molecule to be aromatic due to π-electrons, with just three carbon atoms and two hydrogen atoms. It has now been detected in the atmosphere of Titan, one of Saturn’s moons[1] and joins benzene, another aromatic molecule together with the protonated version of cyclopropenylidene, C  3  H  3   +  also found there.

I occasionally spot an old blog that emerges, if only briefly, as “trending”. In this instance, only the second blog I ever wrote here, way back in 2009 as a follow up to this article.[1] With something of that age, its always worth revisiting to see if any aspect needs updating or expanding, given the uptick in interest.
Blasts from the past: a snapshot of online content in chemistry, ~1994-1998.
Authors: Rzepa Henry
Published: November 2023

With universities around the world having to very rapidly transition to blended learning (a mixture of virtual and face-2-face experiences) with a very large component based on online materials, I thought it might be interesting to try to give one snapshot of when the online experience started to happen in chemistry. My start point will in fact be 1993, when the method of exposing online content currently in use (the “web”) really got going.
Two record breakers for the anomeric effect; one real, the other not.
Authors: Rzepa Henry
Published: November 2023

The classic anomeric effect operates across a carbon atom attached to oxygens. One (of the two) lone pairs on the oxygen can donate into the σ* orbital of the C-O of the other oxygen (  e.g.  the red arrows) tending to weaken that bond whilst strengthening the donor oxygen C-O bond.  Vice versa  means  e.g.  the blue arrows weakening the other C-O bond.
The Willgerodt-Kindler Reaction: mechanistic reality check 3. A peek under the hood for transition state location.
Authors: Rzepa Henry

The two previous surveys of the potential energy surface for this, it has to be said, rather obscure reaction led to energy barriers that were rather to high to be entirely convincing. So here is a third possibility. The red section corresponds to the previous exploration, in which a 3-membered sulfur ring intermediate was mooted. Here we go back to a 3-ring with nitrogen instead.
Santa’s Little Lua Scripts

Santa sighted deeply as worry and uncertainty gave way, leaving a feeling of relieve and accomplishment. The year was one of the worst he’d seen so far. Large numbers of his helpers were moving from the North Pole to Antarctica to satisfy their ambient temperature preferences. There would be many telecommuting Elves this year, and each helper enjoyed additional autonomy. Tying everything together was a challenge.

One of the many great things about free and open source software and the whole GNU/Linux ecosystem are the simple yet powerful tools available. The possibilities enabled by almost trivial programs are incredible. A very positive side effect this has on me is that I like to go and explore technologies with the tools at my disposal.
