På vej mod en pædagogik for bæredygtig udvikling i dagtilbud
Authors: Broström Stig , Frøkjær Thorleif
Published: August 2023

Daginstitutioner har de seneste år udvidet børns naturundersøgelser med et målrettet klima- og bæredygtighedsperspektiv. Udviklingsarbejder og forskning peger på, at en pædagogik for bæredygtighed må overskride en moralisering og voksenformidling og tage afsæt i børns nysgerrighed, undren, egne undersøgelser samt skabende leg. Nyere forskning viser, at forskellige former for sciencepædagogisk praksis og pædagogstøttet leg med fokus på natur- og bæredygtighedstemaer kan bidrage til børns viden om og bevidsthed om bæredygtighed. I forlængelse heraf er udviklet praksisformer, hvor børn og pædagoger opbygger store fælleslege, såkaldte playworlds, hvor de i et legeunivers behandler forskellige klima- og bæredygtighedstemaer, hvilket Marylin Fleer betegner scientific playworlds, altså en legeverden med fokus på science, hvor man med en narrativ struktur og leg undersøger forskellige naturfænomener. I artiklen illustreres teoretisk og praktisk idéen om konstruktion af en ”bæredygtigheds-legeverden”, hvor metoden og de tilknyttede pædagogiske tilgange uddybes. Natur- og bæredygtighedsstudier kan medføre angst og håbløshed, hvilket pædagogerne søger at balancere med håb og optimisme. Afslutningsvis begrunder og uddyber vi det relevante og påtrængende i at indoptage og videreudvikle uddannelse for bæredygtig udvikling i pædagoguddannelsen og i den pædagogiske videreuddannelse.
Læreprocesser i et landskab af praksisfællesskaber
Authors: Lehn Sine , Holen Mari
Published: August 2023

The article explores how nurses form their professional identity through orientations in and out of different communities of practice that they encounter during their basic education and first encounters with the labour market. Inspired by Wenger-Trayner and Wenger-Trayner (2015), professional identity is understood as subjective orientations in the landscape of communities of practice that constitute the nursing profession. The analysis is empirically grounded in qualitative, longitudinal studies of a group of nurses who have been ethnographically followed for seven years so far. The analysis shows how nurses' professional identity in 2023 develops as movements through a landscape of communities of practice. The analysis shows how professional identity is shaped by participation within the individual community of practice, and that this participation involves both engaging and disengaging learning processes.
Professionsidentitet på tværs
Authors: Nielsen Birgitte Lund , Lang Nanna R. , Grosen Trine H. , Høyer Hanne
Published: August 2023

In the paper differences and similarities comparing professional identity in educations for Nurse, Teacher and Bachelor of Nutrition and Health are discussed. Professional identity formation is conceptualized as a fluid and socially negotiated process. There are international studies about professional identity for nurses and teachers, but a lack of comparative studies. The empirical material are group interviews with students and educators analyzed by reflexive thematic analysis. Both groups are asked about the collective professional identity and experiences with external understandings (based on pictures), and the students also about their (pre)professional identity. The analyses show that all three are professions working with empathy in human relations. There are however different stereotypes related to the external understanding of the professions. The student teachers have experienced to a high degree to have to defense their educational choice and position themselves in opposition to the traditional picture of transmissive teaching. The educators and student nurses challenge the picture of a “nice girl”. They refer to the present political focus and refer to the identity as challenged. Bachelor of Nutrition and Health is a new and somewhat diffuse profession. Acting on evidence but also with respect for the individual is formulated as a core.

Particular attention is paid to how the mask is interpreted and used, based on tradition, to create and enhance stage effects and deepen meaningful symbolism in modern performances. The relevance of this work lies in the typology and classification of common and distinctive characteristics of similar, but at the same time unique artifacts of various theatrical cultures of the East and West on the example of the use of masks in productions in the past and present. Addressing this topic can help to establish intercultural ties, facilitate intercultural communication and reduce the degree of civilizational contradictions in a multipolar world. The scientific novelty of the study lies in the results of processing the original selection of case studies, scientific publications and literary sources. The purpose of the study is to search for the features of the perception and understanding of masks in various theatrical systems. To achieve this attitude, the history of masks in different countries, their semantics are analyzed, in particular, the ancient Chinese thermal culture and the ancient Greek theater, as well as the Italian comedy dell'arte are compared. In conclusion, we note that in different theatrical systems, the mask has unique symbols and uses. Thus, it reveals the complex and contradictory human nature, reveals the unknown and people's fear of reality, embodies and expresses emotions, provides the rhythm and sharpness of the development of the drama, deepens the meaning of ongoing events.

Surface phonon polaritons (SPhP) as an alternative constituent for mid-infrared (MIR) nanophotonic applications have attracted extensive attention and they maybe solve the intrinsic loss problem of plasmonics. SPhP arise in polar dielectrics due to IR-active phonon resonances, leading to negative permittivity within the Reststrahlen band. Although SPhP have great potential in enhancing the interaction between light and matter in the infrared region, it is still limited to enhance optical fields and fixed resonance band because of the existing Reststrahlen band. Moreover, active manipulating of phonon polaritons in MIR range remains elusive. The significant research progress of natural van der Waals (vdW) crystal and heterostructures have been made, which are characterized by an anisotropic polaritonic response, leading to elliptical, hyperbolic, or biaxial polaritonic dispersions. Among these structures, SPhP with hyperbolicity in α-MoO3 are of particular interest, due to not only the strong field confinement, low losses, and long lifetimes, but also the natural in-plane anisotropic dispersion. A heterostructure composed of a biaxial vdW material (α-MoO3) and a Weyl semimetal (WSM) is proposed to study the active tunability of anisotropic SPhP. The control of polaritons can show more degrees of freedom, which has not yet been addressed. Under the incident condition of transverse magnetic incident wave, the reflection coefficient and field distribution in the heterogeneous system are accurately solved by the 4×4 transfer matrix method, and the dispersion properties of anisotropic SPhP are described in detail. Variation of dispersion spectrum with azimuthal angle and α-MoO3 thickness is presented. The research results indicate that mode hybridization and dispersion manipulation can be realized by controlling the azimuth angle and the thickness of α-MoO3. More importantly, the Fermi level of WSM enable the adjustment of dynamic dispersion curve, which depends on the change of external temperature. Isofrequency curves of hybridized SPhP at different Fermi levels are also demonstrated. By chemically changing the Femi level of α-MoO3, the topology of polariton isofrequency surfaces transforms from open shape to closed shape as a result of polariton hybridization. Therefore, our research is helpful in further optimizing and designing active optoelectronic devices based on vdW materials, which have good application prospects in infrared heat radiation and biosensing.

The discharges with negative triangularity have lower turbulence induced transport and better energy confinement, so the tokamak with negative triangularity is recognized to be a better choice for future fusion device. In order to explore the features of the energetic particle driven instabilities with negative triangularity, the kinetic-magnetohydrodynamic hybrid code M3D-K is used to investigate the linear instability and nonlinear evolution of the fishbone driven by energetic ions with different triangularity. Based on EAST-like parameters, it is found that the negative triangularity destabilizes the ideal internal kink mode, but stabilizes the fishbone instability. Nonlinear simulations show that the fishbone instability with negative triangularity is hard to saturate without fluid nonlinearity. The possible explanation is that the orbits of fast ions are located more centrally with negative triagularity, so the energy exchange between energetic ions and the fishbone is more efficient than that with positive triangularity. These simulation results demonstrate that the negative triangularity does not have an obvious advantage over the positive triangularity, with the fishbone driven by energetic particles considered.

Excimer laser plays an important role in the national economic production because of its short wavelength, high repetition frequency and large energy. In the output characteristics of excimer lasers, high beam quality and high energy stability are the characters of high-end excimer light source, and whether the excimer laser system can sufficiently develop the preionization process is the key to output laser pulses with high beam quality and stable energy. This paper is mainly to study the preionization process of ArF excimer laser, and establish one-dimensional simulation calculation model and two-dimensional simulation calculation model. Based on the fluid calculation method of Comsol Multiphysics software, the numerical simulation analysis and calculation are carried out, with the study focusing on the ionization wave propagation process in the preionization process and the relationship between preionization and main discharge. The results show that the spatial structure of corona rod and main electrode should be considered comprehensively when an excimer laser system is designed. Appropriate preionization structure and voltage can make the main discharge triggered during the maintenance of free electrons, which can effectively reduce the discharge voltage, avoid streamer and arc discharge, and improve the output beam quality and system energy stability.

In this article, the first principles calculation method is used to study the MoSi2N4/GeC heterostructures, and calculate its structural, electronic, and optical properties. And the effects of different biaxial strains and vertical electric fields on the band structure and optical absorption characteristics of the heterostructures are also investigated. MoSi2N4/GeC heterostructure is an indirect bandgap semiconductor with a bandgap of 1.25 eV, with the built-in electric field direction pointing from the GeC layer to the MoSi2N4 layer. In addition, its photogenerated carrier transfer mechanism conforms to the S-type heterostructures mechanism, thus improving the oxidation reduction potential of photocatalytic water decomposition, making it fully meet the requirements of photocatalytic water decomposition with pH = 0–14. Under biaxial strain, the band gap first increases and then decreases with the increase of compressive strain, and the light absorption performance in the ultraviolet region increases with compressive strain increasing. The band gap decreases as tensile strain increases, and the light absorption performance in the visible light region is enhanced in comparison with its counterpart under compressive strain. Under a vertical electric field, the band gap increases with positive electric field increasing, and decreases with negative electric field increasing. In summary, MoSi2N4/GeC heterostructures can be used as an efficient photocatalytic material in some fields such as optoelectronic devices and photocatalysis.

Quantum simulation serves as a significant tool for studying and understanding novel phenomena in the quantum world. In recent years, it has be realized that apart from quantum platforms, classical systems like photonic crystals, phononic crystals, and mechanical oscillators can also be used to simulate quantum models by analogizing the Schrödinger equation. Among these systems, electrical circuits have emerged as a promising simulation platform owing to their low cost, technological maturity, and ease of scalability, successfully simulating numerous important quantum phenomena. Meanwhile, non-Hermitian physics breaks the Hermiticity of systems’ Hamiltonians in traditional quantum mechanics, providing a fresh perspective for understanding the physics of quantum systems, particularly open quantum systems. Non-Hermitian systems, owing to their manifestation of unique phenomena absent in Hermitian systems, have become emerging research subjects in various fields of physics. However, many non-Hermitian phenomena require specialized configurations that pose relatively high technical thresholds on quantum platforms. For instance, the non-Hermitian skin effect typically requires systems to possess non-reciprocal hopping between lattice sites. Therefore, utilizing flexible electrical circuits to simulate non-Hermitian physics becomes a natural choice.

This paper provides a short review of the current experimental progress in simulating non-Hermitian lattice models by using electrical circuits. It offers a brief introduction to the relevant knowledge of non-Hermitian physics, including mathematical concepts and novel phenomena, as well as the simulation theory of electrical circuits, including the mapping theory of the lattice models, the introduction of non-Hermiticity, and the measurement of physical quantities. The aim is to provide readers with a reference for better understanding or engagement in related researches, thus promoting further development in this field.

Pump-probe-based photoacoustic imaging is an innovative technique for high-specificity molecular imaging in deep tissues. Compared with conventional photoacoustic imaging, this method effectively eliminates the interference from blood signal and other background signal, enabling the detection of subtle target molecules. Additionally, the manipulating of the time delay between the pump laser and probe laser can facilitate non-invasive mapping of oxygen partial pressure distribution within tissues. To quantify the photoacoustic pump-probe imaging, we use methylene blue as the molecular probe to monitor changes in oxygen partial pressure within a hemoglobin solution. Utilizing a Gaussian noise model, we investigate the relationship between the stability of the triplet-state difference signal and the average number, and also evaluate the error associated with measuring oxygen partial pressure. The results demonstrate that the detection accuracy of the system is better than 33 mmHg (1 mmHg = 133 Pa) in the oxygen partial pressure range of about 300 to 550 mmHg after 200 times of averaging. This research will play a significant role in guiding the further advancement and application of pump-probe-based photoacoustic imaging technology.
The experiences of COVID-19 preprint authors: a survey of researchers about publishing and receiving feedback on their work during the pandemic
Authors: Rzayeva Narmin , Henriques Susana Oliveira , Pinfield Stephen , Waltman Ludo
Published: August 2023

The COVID-19 pandemic caused a rise in preprinting, triggered by the need for open and rapid dissemination of research outputs. We surveyed authors of COVID-19 preprints to learn about their experiences with preprinting their work and also with publishing their work in a peer-reviewed journal. Our research had the following objectives: 1. to learn about authors’ experiences with preprinting, their motivations, and future intentions; 2. to consider preprints in terms of their effectiveness in enabling authors to receive feedback on their work; 3. to compare the impact of feedback on preprints with the impact of comments of editors and reviewers on papers submitted to journals. In our survey, 78% of the new adopters of preprinting reported the intention to also preprint their future work. The boost in preprinting may therefore have a structural effect that will last after the pandemic, although future developments will also depend on other factors, including the broader growth in the adoption of open science practices. A total of 53% of the respondents reported that they had received feedback on their preprints. However, more than half of the feedback was received through “closed” channels–privately to the authors. This means that preprinting was a useful way to receive feedback on research, but the value of feedback could be increased further by facilitating and promoting “open” channels for preprint feedback. Almost a quarter of the feedback received by respondents consisted of detailed comments, showing the potential of preprint feedback to provide valuable comments on research. Respondents also reported that, compared to preprint feedback, journal peer review was more likely to lead to major changes to their work, suggesting that journal peer review provides significant added value compared to feedback received on preprints.

Desde o início do século XXI, assuntos como inovação e sustentabilidade vêm tomando os holofotes no mercado corporativo. Isso se deu graças à saturação do mercado produtivo tradicional. Com isso em mente, este trabalho consistiu em uma revisão bibliográfica com o intuito de realizar uma reflexão sobre a importância do planejamento estratégico e suas principais ferramentas aplicadas às startups. O estudo em questão partiu da problemática “Como o Planejamento Estratégico pode transformar uma ideia inovadora em uma startup de credibilidade e atrativa para os investidores?”. Teve como objetivo geral demonstrar a importância do planejamento estratégico na criação e consolidação das startups. A justificativa desse estudo parte da concepção de que não existe uma receita para se ter uma ideia, mas para que ela seja validada e implementada, faz-se necessário a uso de ferramentas de planejamento estratégico. Como metodologia, foi aplicada uma pesquisa qualitativa descritiva com foco na revisão de literatura. Os assuntos Planejamento Estratégico (PE) e Startups foram abordados de maneira conjunta, sendo o PE um conjunto de ferramentas de suporte para a consolidação das startups no mercado. Os artigos pesquisados tiveram um período misto, sendo alguns de referência histórica de até 80 anos e a grande maioria de período mais recente, de até 12 anos. Como principais resultados, podemos destacar que a adoção do planejamento estratégico diminui substancialmente a taxa de mortalidade das companhias no mercado, auxiliando no fomento da economia, na geração de empregos e na criação de inovação, melhorando a vida das pessoas e facilitando cada vez mais seu dia a dia.

Nas atividades de inovação, a Administração é chamada à participação cooperativa, colaborativa, inclusiva, responsável e sustentável em face às competências procedimentais e conceituais esperadas no profissional preparado a tratar questões complexas e interdisciplinares. A expectativa da sociedade é de que os colaboradores que participam de atividades inovadoras nos locais de trabalho tenham construído competências já durante seus estudos. A graduação em Administração no Brasil oferece à sociedade, via suas dinâmicas  de ensino-aprendizagem, cidadãos comprometidos orientados à inovação para resolver problemas da sociedade e das organizações? Explorou-se o problema via contraposição das Diretrizes Curriculares Nacionais em Administração com a abordagem da Pedagogia da Inovação, apresentando uma sistematização dos paradoxos na proposição estratégica da política pública, em função da crítica interdisciplinar de Administração, Economia e Pedagogia. Como corolário propõe-se que a implementação da Pedagogia da Inovação em Administração pode ser compreendida em função de três problemáticas (seguir as pessoas X seguir o dinheiro; formação e escolha dos professores; cursos com educação baseada na evidência X baseada no status quo dos processos orientados pelo conteudismo). Finaliza-se considerando a Administração, enquanto estratégica à inovação, construída com fragilidades político-estratégicas e pedagógicas a serem trabalhadas.

En la laguna de las Ilusiones, Villahermosa, Tabasco, México, las especies de aves interactúan con elementos antrópicos del paisaje. Se realizaron avistamientos de aves acuáticas con el método de conteo por punto fijo durante la temporada de secas y de lluvias del año 2020 en 12 sitios de muestreo en la laguna. Se registraron variables urbanísticas, físicoquímicas del agua, de vegetación y de macrohábitats para evaluar su influencia en las aves acuáticas. Se registró un total de 1,134 individuos pertenecientes a 8 órdenes, 12 familias y 25 especies. Las especies más avistadas fueron Ardea alba, Egretta thula y Butorides virescens. La diversidad de especies (índice de Shannon) fue mayor en la temporada de secas (H = 2.40 bits) y menor en la temporada de lluvias (H = 1.89 bits). El análisis canónico demostró que la riqueza de especies disminuyó a medida que incrementó el porcentaje de urbanización en las inmediaciones de los sitios de muestreo.

This study aims to investigate income diversity and food security status among people living in the Haor area, with the objective of informing development policies for these regions. The research focused on assessing the socioeconomic characteristics, income diversity, and food security status of 120 randomly selected households in the Nikli and Tarail upazilas within Kishoregonj district, Bangladesh. Data was gathered through direct face-to-face interviews. The study revealed that the majority of households (91.66%) were male-headed, with an average family size of 5.10 members. A significant proportion (62.5%) of respondents fell within the 30-64 age group. Education-wise, a substantial portion (39.16%) of respondents had a secondary level of education, while 25% were employed in the agriculture sector. Approximately 45.83% of households were constructed with tin materials. The average monthly income and expenditure were Tk. 9536 and Tk. 8316, respectively. Income diversification was found to be prevalent among the respondents; however, within individual households, diversification was limited. The Simpson's and Shannon's indices of diversity for income were 0.84 and 0.88, respectively. About 25% of households were classified as ultra-poor, 29.17% as hard-core poor, and 20.83% were in the category of absolute poverty. On the positive side, 25% of the sample households were deemed non-poor. These findings underscore the urgent need for policy changes to address poverty eradication and enhance the standard of living in the study area. By understanding the socioeconomic dynamics and food security challenges faced by Haor communities, policymakers can devise targeted interventions to uplift the living conditions and well-being of the residents in these regions.

Pharmaceutical medications must be stable to preserve their efficacy and safety over the                  period of their shelf lives. Studies on force degradation are crucial for identifying probable degradation pathways and identifying extreme stresses that may lead to the breakdown of the pharmaceutical product. This report offers a thorough analysis of the force degradation tests performed on Clomifene citrate tablets. Evaluation of the effects of several stress factors, including temperature, humidity, light, and mechanical forces, on the stability of clomifene citrate is the                   main goal. To replicate actual storage and handling situations, the study used stress testing                criteria specified by the International Conference on Harmonization (ICH). According to the                 study, temperature and humidity have the biggest roles in the degradation of Clomifene citrate tablets. In this article the FDS was performed by using a stainless-steel column (250 mm x 4.6 mm) packed with Butylsilane C4 (5µm) L26, detector 233nm, mobile phase; mobile Phase was              prepared by mixing 550 volumes of methanol, 450 volumes of water and 3 volumes of triethylamine. Then adjust the pH to 2.5 with phosphoric acid. Flow rate; 1 mL/mint. The quantification and hyphenation of the instrumental analysis were successfully accomplished using the developed method.

The management of Pink bollworm, a worldwide pest in cotton is mostly dependent on chemical insecticides which lead to several implications and warrant the exploration of other methods. Use of sex pheromones for management of insect pests is not a new-fangled one but need be studied extensively for effective pest management. Hence, a study was conducted at RARS, Lam, Guntur, Andhra Pradesh for two consecutive seasons to study the effectiveness of mass trapping in pink bollworm management. The experimental results showed that the mean moth catch was highest from sleeve traps when compared to funnel trap and delta traps with sticky liners irrespective of trap densities. The mean number of larvae and locule damage was significantly low coupled with high seed cotton yield from the plots with sleeve traps at trap densities of 50 and 20 traps/ha.

Carrot is an important root vegetable which plays an important role in human health. Globally, Post harvest diseases are the major constraint in carrot production, especially soft rot which resulting in severe yield loss. Early diagnosis of these post-harvest diseases paves a way for reducing the economic losses. Carrot samples showing typical rotting symptoms were collected from markets of four different districts of Tamil Nadu and the pathogen involved were isolated. Severe carrot soft rot incidence (66.74%) was observed in samples collected from Ooty area of The Nilgiris district and the least disease incidence of (16.21%) was recorded in Perundurai of Erode district. Pathogenicity of soft rot pathogen were conducted and the virulent isolates were identified based on Percent Disease Index (PDI) showing >50% rotting falls under disease grade 9 using disease grade scale (0 to 9). The bacterial isolates (KPB-7 and OCB-5) causing soft rot were characterized using various biochemical assays where in they showed positive response for methyl red, H2S gas production, KOH and catalase tests besides showing negative response for gram’s reaction. Furthermore, molecular characterization of 16s rRNA region revealed the soft rot isolate (KPB-7) as Pectobacterium carotovorum subsp carotovorum (with an accession number OR251119).
