Published: April 2024

En un tiempo donde el capitalismo neoliberal ha intensificado la explotación, el despojo, la represión y el desprecio hacia los pueblos del sur global, las expresiones de lucha y resistencia que emana de los pueblos indígenas se convierte en una referencia para grupos sociales multidiversos que compartimos el objetivo de construir un mundo donde quepan muchos mundos. En este contexto, desde la sociedad civil organizada, experimentamos formas de acompañar estos procesos emancipatorios, buscando aprender para imaginar sobre nuestros territorios urbanos, formas y modos propios de autonomía. Con este foto ensayo, queremos compartir la experiencia del CICC, una organización sin fines de lucro integrada por hombres y mujeres, indígenas y mestizos, que hemos elegido ejercer la solidaridad de forma militante, y que en nuestro andar hemos encontrado en el arte y la cultura, una luz que en los momentos más difíciles, muestra la posibilidad de otro mundo.

Published: April 2024

BACKGROUND: Knowing whether shift work negatively affects the immune system’s response to COVID-19 vaccinations could be valuable for planning future vaccination campaigns for healthcare workers. We aimed to determine the impact of working late or night shifts on serum anti-SARS-CoV-2 spike protein immunoglobulin G (anti-S) antibody levels after primary SARS-CoV-2-mRNA vaccination.
METHODS: To obtain detailed information on shift work, we sent a separate online questionnaire to 1475 eligible healthcare workers who participated in a prospective longitudinal study conducted in 15 healthcare institutions in Switzerland. We asked all vaccinated healthcare workers with available anti-S antibody levels after vaccination to complete a brief online survey on their working schedules within one week before and after primary mRNA vaccination. We used multivariate regression to evaluate the association between work shifts around primary vaccination and anti-S antibody levels. We adjusted for confounders already known to influence vaccine efficacy (e.g. age, sex, immunosuppression, and obesity) and for variables significant at the 0.05 alpha level in the univariate analyses.
RESULTS: The survey response rate was 43% (n = 638). Ninety-eight responders were excluded due to unknown vaccination dates, different vaccines, or administration of the second dose shortly (within 14 days) after or before serologic follow-up. Of the 540 healthcare workers included in our analysis, 175 (32.4%) had worked at least one late or night shift within seven days before and/or after primary vaccination. In the univariate analyses, working late or night shifts was associated with a nonsignificant −15.1% decrease in serum anti-S antibody levels (p = 0.090). In the multivariate analysis, prior infection (197.2% increase; p <0.001) and immunisation with the mRNA-1273 vaccine (63.7% increase compared to the BNT162b2 vaccine; p <0.001) were the strongest independent factors associated with increased anti-S antibody levels. However, the impact of shift work remained statistically nonsignificant (–13.5%, p = 0.108).
CONCLUSION: Working late or night shifts shortly before or after mRNA vaccination against COVID-19 does not appear to significantly impact serum anti-S antibody levels. This result merits consideration since it supports flexible vaccination appointments for healthcare workers, including those working late or night shifts.

Ganzheitlichkeit aus psychologischer Sicht
Authors: Utsch Michael
Published: April 2024

Ganzheitlichkeit ist ein zentrales Motiv esoterischer Weltanschauung. Besonders häufig begegnet es im Bereich der Alternativmedizin, die auch als „Ganzheitsmedizin“, „integrative“, „holistische“ oder „komplementäre Medizin“ bezeichnet wird. Wissenschaftlich wird diese Sehnsucht nach Verbindung mit dem „großen Ganzen“ zur Beantwortung existenzieller Aporien und zur Überwindung von Sinnlosigkeit als „spirituelles Grundbedürfnis“ beschrieben, das angesichts von Tod und Sterblichkeit auch in säkularisierten Gesellschaften nachzuweisen ist (Büssing 2021). Die ganzheitliche Perspektive nimmt die Person als Körper-See⁠le-Geist-Einheit in den Blick. Das stark strapazierte Konzept der Ganzheitlichkeit wird bis heute als Erklärungsmodell in den vielfältigen Heilungsangeboten der sogenannten Gebrauchsesoterik verwendet. Dieser vieldeutige und missverständliche Containerbegriff umfasst die unterschiedlichsten religiös-weltanschaulichen Traditionen, Ideen, Organisationen und Praktiken. Ohne nähere Erläuterungen bleibt der Begriff ein Etikett ohne Aussagekraft. Manche Religionswissenschaftler:innen beklagen, dass ein ernsthaftes Gespräch mit „der Esoterik“ durch polemische, von eurozentrischer Kultur und kirchlicher Deutungsmacht beförderte Abgrenzungen erheblich erschwert wird (Hanegraaff 2023). Es wird vor schnellen Urteilen gewarnt und zu mehr Differenzierung aufgefordert. Der vorliegende Beitrag folgt dieser Aufforderung, indem er nicht den vagen Überbegriff „Esoterik“, sondern den damit verbundenen Topos der Ganzheitlichkeit ins Zentrum seiner Betrachtungen rückt. Für das Verständnis von Esoterik ist dieser Topos von grundlegender Bedeutung. Darüber hinaus wird hier vor allem die Perspektive der Psychologie eingenommen. Woher stammt die Idee der Ganzheitlichkeit? Was sind Möglichkeiten und Grenzen der Einbeziehung ganzheitlicher Methoden in die Krankenversorgung? Und welche Rolle kommt dabei der Seelsorge zu?
Funkce vizuálních prostředků v učebnicích cizích jazyků na příkladech z učebnic češtiny jako cizího jazyka
Authors: Jirásková Petra
Published: April 2024

Metodologická studie na konkrétních ukázkách z učebnic češtiny jako cizího jazyka popisuje různorodé funkce, které mohou být realizovány vizuálními prostředky. Pozornost je věnována vztahu vizuálních prostředků a verbálního textu, jejich vzájemné komplementaritě a přínosnosti pro pochopení předávaných informací i jejich uchování v paměti. Dále článek poukazuje na nezbytnost vzdělávání autorů učebnic, učitelů i žáků a studentů v oblasti vizuální gramotnosti, tak aby dokázali vizuální prostředky co nejefektivněji didaktizovat a využívat, případně sami vytvářet. Sám text k tomu přispívá rozborem funkcí vizuálních prostředků v učebnicích češtiny jako cizího jazyka, zaměřuje se na vybrané funkce pedagogicko-didaktické a psychologické a popisuje, případně na ukázkách demonstruje jejich projevy na různých rovinách výuky jazyka od řečových dovedností přes výslovnost až po gramatiku nebo reálie. Upozorňuje také na didaktická rizika, která využívání vizuálních prostředků doprovázejí. Text tak podává učitelům základní přehled možností, jak vizuální prostředky v učebnicích využívat, tak aby z nich dokázali vytěžit maximum a zároveň byli schopni odhalit ty, jež jsou v nějakém ohledu problematické, nefunkční či projevující znaky některého z didaktických rizik.

Authors: Krejčí Vladimíra , Kašperáková Dagmar , Krejčí Oldřich , Tomanová Pavla
Published: April 2024

The aim of our work was to use a statistical model to determine the degree of susceptibility assessment in the area of the Chřiby Highland and northern part of the Kyjovská pahorkatina Hilly land and then compare the results with field verification of their actual occurrence in a part of this previously unmapped area. Studied part with a total area of 353,47 km2 is frequently affected by landslides (580 landslides covering 9 % of the area). The mapped area and the results comparing with the final landslide susceptibility map showed that more than 85 % of the mapped landslides are located in areas of high and very high landslide susceptibility. For locations that were not detected by this statistical method, but where landslides were nevertheless subsequently mapped, it was found that their origin was initiated by phenomena other than the input conditions used for the analysis. The results of the analysis were verified by field research of the territory, which had not previously been comprehensively mapped (south part of the model area). A total of 98 landslides were newly identified or revised, covering a total area of 4 km2, corresponding to 7.4 % of the area reconnaissanced.
STUDY OF THE VARIABLE STARS V10 AND C6 IN MESSIER 13
Authors: Violat-Bordonau F.
Published: April 2024

We have studied the variable star V10 and the new variable candidate C6 (announced in 2019), located in Messier 13, using the filtered CCD images -in the V bandobtained in the campaigns of 2019, 2020 and 2021. We have previously determined their precise  and  coordinates (J2000) to identify them in a crowded field. We find the V10 constant in light in the three campaigns: the star is listed in the Catalogue of Variable Stars in Globular Clusters as non-variable. C6 has presented low-level variations from 0.102 to 0.138 mag without regularity; these values are lower than 0.44 mag in the V band detected by its discoverers. Although we find different periods, none draw a coherent light curve. We have also analysed the photometric measurements obtained by ASAS-SN between 2019 and 2023 in the SLOAN-g band, identifying oscillations with a maximum amplitude equal to 0.188 mag;. However, we find two possible periods, none producing a quality light curve. All data suggest that C6 is a new variable star of type L, irregular because no single period fits all of the data: we propose the name V65 for it.

Roles in Research Teams: The Perspective of University Commercialisation
Authors: Zastempowski Maciej , Kalocińska-Szumska Aleksandra , Łaskowska Justyna
Published: April 2024

Although the investigation of team roles has been a focus of scientific research over an extended period, one of the less recognised issues in this area is the functioning of research teams, especially in commercialising their scientific results. Drawing from a comprehensive examination of the literature and the concept of ‘The A-to-F Model’ by de Bes and Kotler, this paper aims to broaden the knowledge about the research team’s roles and their influence on commercialising their results. To do this, in the empirical part, we use the data from a study of 496 scientists from one of the leading research universities in Poland. The results of the estimated probit regression models showed the inconsistency with ‘The A-to-F Model’. Only two of the six roles, i.e., creator and executor, are essential. The activator, browser, developer, and facilitator were statistically insignificant.
Bud Fowler Beyond the Box Score
Authors:   Fort Hays State University, Eberle Mark
Published: April 2024

John W. Jackson, better known as Bud Fowler (1858–1913), was a Black baseball player, captain, manager, umpire, organizer, and promoter. He was also a barber, playwright, and song writer. His baseball career spanned at least 33 years, from 1877 to 1909. In 1878, Fowler became the first known Black baseball player in the major or minor leagues, and he went on to play for a total of 20 minor league clubs and numerous other teams with rosters composed predominantly of white ballplayers during the era of racial segregation. He played for teams from New England to southern California and from the Great Lakes to the Gulf of Mexico. Consequently, he was the most widely known Black baseball player in the country during his lifetime. In 2022, Fowler was inducted into the National Baseball Hall of Fame. This monograph expands on earlier studies of Fowler’s life outside his performance on the diamond, including topics such as playing for multiple teams each year, confronting racism, occupations other than baseball, financial challenges, and the impacts of his baseball career on others.

A Qualitative Study on the Conceptualisation of Mental Health Amongst South Korean Migrants to Australia
Authors: Klingenberg Annemarie , Heo Sunjoo , Eliott Jaklin
Published: April 2024

An increase in global awareness of the mental health needs of migrant communities, and recognition of the underutilisation of support services by these communities, has prompted calls for culturally appropriate and competent interventions to address their needs. Providing such culturally effective treatment and mental health services, particularly for culturally and linguistically diverse (CALD) subgroups, requires understanding their perspectives on mental health. This research was led by a migrant from South Korea, living, studying, and working in Australia, and explored how South Korean migrants to Australia talk about mental health and what they need to support their mental health. A qualitative study was conducted via telephone or online web-conferencing using semi-structured interviews. A critical realist approach facilitated consideration and understanding of themes addressing participant perspectives of what promoted South Korean migrants’ mental health in the Australian context. All interviews were thematically analysed, and three major themes centred around (shifting) cultural norms were identified. These were increasing individualism (e.g., through self-discovery); the expression of individually new-found norms; and issues around belonging in society. The purpose of this article is to translate these findings into counselling practice and community initiatives to provide practitioners with greater insights into concepts this population group has identified as impacting their mental health.

Authors: Spiroski Milla , Igor Belenichev
Published: April 2024

Introduction: Chronic gingivitis is the most common inflammatory periodontal disease, affecting up to 50% of adults. Low-power diode laser therapy (LLLT) has been proposed as an alternative treatment for chronic gingivitis.

Methods: A double-blind randomized controlled study was conducted to evaluate the effectiveness and safety of LLLT in the treatment of chronic gingivitis. Thirty patients with chronic gingivitis were randomly divided into two groups: the control group (n=15) and LLLT group (n=15). The LLLT group received LLLT therapy for 10 minutes per session, twice daily for 14 days. Plaque index (PI), gingival bleeding index (GI), periodontal pocket depth (PPD), and degree of attachment loss (CAL) were measured before and after treatment.

Results: The LLLT group showed significant reductions in PI, GI, PPD, and CAL compared with the control group. The difference between the two groups was statistically significant (p<0.05). No side effects were reported during the study.

Conclusion: LLLT has been proven to be effective and safe in the treatment of chronic gingivitis. LLLT may be a useful alternative treatment option for patients with chronic gingivitis.

Introduction: Composite dental filling materials are widely used for dental restoration because of their aesthetic properties and durability. However, the choice of appropriate filling material is still a matter of debate. The aim of this study was to compare the effectiveness and safety of nano-hybrid and microhybrid composite dental filling materials in a double-blind randomized clinical study at Ulaanbaatar Hospital, Mongolia.

Methods: A total of 60 patients with posterior dental caries were recruited and randomly assigned to receive nano-hybrid or microhybrid composite dental fillings. Patients were clinically evaluated at 6 months, 12 months, and 24 months after patching to assess patch retention, color change, sensitivity, and other complaints.

Results: The patch retention rates in the two groups were not significantly different (p>0.05). The color change in the nano-hybrid group was less than that in the microhybrid group (p<0.05). Tooth sensitivity in the two groups was not significantly different (p>0.05). No other complaints were reported by the patient.

Conclusion: Nano-hybrid and microhybrid composite dental filling materials have equivalent effectiveness and safety within a period of 24 months. However, nano-hybrid showed less color change compared to microhybrid.

Authors: Jovanovski Dalibor
Published: April 2024

The occurrence and spread of malaria amongst the warring parties on the Macedonian1 front brought about the appearance of completely new approaches in its treatment and prevention among the solders on both sides of the front line. The British experience in preventing the spread of malaria is a very interesting topic for analysis. The Macedonian front became an enormous experimental field for malaria research and experiments carried out by British medical and military personnel. The impact malaria had on the readiness of British soldiers concerning their combat activities on the front forced the command structures to undertake preventive measures in order to halt its spread. Thus, the British military command in Salonica became involved in draining swamps, clearing streams, oiling, and other methods of treating breeding places, fumigation and spraying, mosquito-proofing the huts and the carrying quinine prophylaxis.

Introduction. Lyme disease is an infectious disease transmitted by the Ixodes ticks and is manifested by damaging various organs and systems (most often-migrating erythema, damage to the nervous system, musculoskeletal system, heart, liver and eyes). According to various authors, heart damage in Lyme borreliosis ranges from 4% to 10% and is an understudied pathology. Case report. The article describes a clinical case of infectious myocarditis associated with Lyme disease in a 51-year-old patient. The course of the disease and the results of treatment of the patient were analyzed. The severe rhythm and conduction disorders were revealed: antrioventricular (AV) block of the first degree, transient AV block of the II degree (Mobitz 2) and III degree, polytopic extrasystoles. Due to timely diagnosis, including serological, prescribed etiotropic antibacterial treatment, the patient achieved a significant improvement in both clinical condition and positive serological and electrocardiogram (ECG) dynamics with improved AV conduction. Conclusions. The most frequent ECG changes in Lyme carditis (LC) are conduction disorders with the development of blockades of various stages. For patients with myocarditis, which is accompanied by complex arrhythmias, and conduction disorders estimated as intermediate and high risk by Suspicious Index in Lyme Carditis (SILC) scale, serological examination should be recommended in order to verify the borreliosis etiology of myocarditis. In this particular case, early diagnostics and prescribed etiotropic treatment, in addition to treatment of heart failure, contributed to a significant improvement in both the clinical condition and positive serological and ECG dynamics.

Introduction/Aim. Patients who undergo kidney transplantation can encounter significant changes in body composition because of weight gain caused by fat mass accumulation and muscle mass loss, resulting in poor graft outcomes. The study aimed to investigate the impact of different obesity parameters on graft function in kidney transplant recipients. Methods. A cross-sectional study was conducted on 80 kidney transplant patients aged 25-75 years (40% females). All were on triple immunosuppressive therapy. Weight, height, waist, and hip circumferences measurements were taken to calculate body mass index (BMI) and waist-to-hip ratio (WHR). Body fat percentage (BF%) was measured using a 4-site skinfold method calculated through the Jackson-Pollock equation utilizing a Cescorf caliper. The patients were divided into two groups depending on their glomerular filtration rate (GFR). Results. BMI showed that 16.28% of males and 10% of females were obese. However, according to BF%, as many as 44.68% of males and 72.72% of females were obese. Statistically significant differences in BMI, WHR, and BF% were observed among patients with normal and lower GFR. After adjustment for covariables, lower GFR was related to higher levels of all obesity parameters. The combination of central obesity (WHR>0.85 for women and > 0.9 for men) and higher BF% was associated with lower GFR compared with that in lean subjects (p < 0.001 for both groups). Conclusion. High BF% and WHR may be important risk factors for reducing GFR in kidney transplant recipients.

Introduction/Aim. The length of tooth enamel conditioning time and the size of bracket bases are some the factors influencing the bond strength between the two adherents. The aim of this study was to compare the shear bond strength (SBS) between two different types of bonded metal brackets and acid-etched enamel surface in two different times. Material and methods. Forty extracted human premolars were randomly divided into four groups. In groups 1 and 2, metal brackets Topic (Dentaurum, Germany) were bonded after etching with 37% phosphoric acid (Gel, Reliance, USA) for 15 s and 30 s, while in groups 3 and 4, metal brackets Equilibrium mini (Dentaurum, Germany) were bonded after etching for 15 s and 30 s. Brackets were bonded using flowable composite Heliosit Orthodontic (Ivoclar Vivadent, Liechtenstein) and light-cured using a LED lamp. The SBS was measured by an electronic dynamometer at a cross-head speed of 5 mm/min. Results. Statistical analysis revealed that SBS is affected by both bracket type (t = 10.62; p < 0.01) and etching time (t = 2.81; p = 0.008). The Equilibrium mini brackets with previous enamel etching for 30 s showed the highest SBS values of 10.8 ± 0.75 MPa, while the Topic brackets with previous enamel etching for 15 s showed the lowest values of 4.85 ± 0.53 MPa. Conclusion. Increasing the etching time of tooth enamel leads to higher values in bond strength, especially when using a bracket with a smaller base.

Introduction/Aim. An increased survival of patients with extensive and critical burns has increased the number of scar deformities in various parts of the human body. Breast lesions particularly affect the physical and mental health of girls and women. Scar deformities manifest in the form of individual scars or large scar fields of the breast and chest. All of this causes a wide variety of possible types of damage and the complexity of their classification. The aim of the work was to develop a classification of postburn scar deformities of the breast based on the definition of key areas of deformity and severity of the lesion to determine the reconstruction plan with optimal use of available healthy tissues of the surrounding areas. Material and methods. The classification of cicatricial deformities of the breast was based on a retrospective study, which was conducted involving 68 patients with lesions of 96 glands (40 unilateral and 28 bilateral). Clinical assessment of the lesion was used, taking into account the segmentation of the breast and adjacent areas, determination of parenchymal deficiency, and the degree of lesion of the mammary-areolar complex. The surface of the breast and adjacent areas of the chest and anterior abdominal wall are divided into 10 segments. The segmentation of areas allowed us to clarify the development of deformities with the selection of their key areas due to scars and to determine the most suitable areas for obtaining the donor tissue for reconstruction. Results. Four types of breast deformities are proposed based on determining the location of scar tissue transformations, the severity of the lesion of the nipple-areolar complex, parenchymal deficiency, and the nature of the deformity. Conclusions. The presented classification of postburn scar deformities of the breast reflects the main features of structural and functional disorders, makes it easy to determine the severity of the deformity, and helps to differentiate and objectively approach the choice of treatment tactics.

Published: April 2024

E-procurement is gaining momentum worldwide as companies realize its transformative potential to improve operational efficiency. Small and medium-sized enterprises (SMEs) strategically use advanced technologies to drive their growth and competitiveness. However, there is a significant research gap, particularly with regard to e-procurement adoption strategies in emerging markets. To address this gap, this study aims to examine the e-procurement adoption strategies used by SMEs in the Republic of South Sudan. This is intended to contribute to existing knowledge about e-procurement adoption strategies, especially in the context of emerging countries. A quantitative cross-sectional design was used for this study. Empirical data were collected through survey questionnaires distributed via email to 300 SMEs in the Republic of South Sudan using Google Forms, achieving a response rate of 71.0 percent. Data analysis involved descriptive statistics, principal component analysis (PCA), relative importance index (RII), and the analytical hierarchy process (AHP). Resultantly, the study categorizes strategies into two main factors: competitive and strategic. In the competitive factor category, allocating resources and analysing existing processes were identified as crucial for successful e-procurement implementation. Conversely, in the strategic factor category, aligning technology with strategic goals, fostering alliances, and addressing resistance were key to ensuring sustained success in e-procurement. These findings contribute to enhancing SME competitiveness and facilitating growth in the digital era by optimizing procurement processes, reducing costs, and gaining a competitive advantage. It is recommended that researchers and practitioners use the insights from this study to guide organisations in effectively allocating resources and aligning e-procurement with overall business goals. Furthermore, fostering alliances to enhance collaboration and knowledge sharing and proactively addressing resistance are crucial for realizing long-term benefits from e-procurement implementation.

Published: April 2024

Community of inquiry (CoI) has been recognized as a design framework for online learning. As its use has been gradually increasing in online graduate programs for teachers, it is important to know how it affects teachers’ professional knowledge. This study examined course design elements/activities together with the CoI presences. The findings from the teacher interviews and the survey data showed: (1) all presences were evident in the course, and (2) activities aligned with social and cognitive presences (i.e., hands-on assignments, peer feedback, collaborative group work, and discussions) enhanced teachers’ professional knowledge. Practical recommendations for course design are presented. The findings suggest CoI can be a model for online teachers’ professional development.
