description: A typical practice of assessment in engineering studies, especially on large Bachelor level courses, is a final exam at the end of the course. This practice is problematic both in terms of learning and teaching, as it does not provide feedback on learning experience or student progress before the course is completed. This study examines the gradual process of moving from a final exam towards continuous assessment that integrates the practices of summative and formative assessment. The aim is to understand how the changes affect student performance on the course over a period of four years. The changes were implemented on a large Bachelor level engineering course. The impact of adding practices of continuous assessment was analyzed in relation to the course pass rate, grade distribution, and student feedback. The results show that replacing the final exam with weekly homework improved student performance. Some of the identified differences are statistically significant. Student feedback implies that moving towards continuous assessment had a positive impact on the learning experience. The results support increased use of continuous assessment in the assessment of student learning on large Bachelor level engineering courses.

description: In order to learn writing and reading Chinese characters within an acceptable timeframe and with a reasonable amount of study time can only be achieved, if the student’s skills and capabilities are known and are effectively considered. Each of the student’s cultural skills needs to be applied specifically to the Chinese characters lesson. In addition the methods, techniques, and as shown above in certain details and if applicable against all traditions even the contents can conveniently be modified. This is how a student can learn Chinese with successful access to one of the most interesting writing systems in the world.

description: Sustainable engineering education requires us to address discrimination and inequity of experience, thereby contributing to a renewal of the engineering profession that reflects a rich diversity of experiences and perspectives. Many students experience discriminatory events in their classrooms, however the presence of teaching assistants in relatively high numbers means that they could provide both proactive support and reactive intervention to support inclusion and combat discrimination. This paper examines teaching assistants’ (TAs) contributions, employing observations from students (3988), student teaching assistants (277) and doctoral teaching assistants (65). We found that (i) students overwhelmingly reported respectful interactions with their TAs, (ii) while both student assistants and doctoral assistants see inclusion as part of their role, student assistants expressed more confidence in their ability to foster inclusion. Our analysis indicates that TAs are a constructive force to build inclusive engineering classrooms, informing our recommendations for improvingcampus culture.
Complete cosmic scenario in the Randall-Sundrum braneworld from the dynamical systems perspective

description: The paper deals with dynamical system analysis of a coupled scalar field in the Randall-Sundrum(RS)2 brane world. The late time attractor describes the final state of the cosmic evolution. In RS2 based phantom model there is no late-time attractor and consequently there is uncertainty in cosmic evolution. In this paper, we have shown that it is possible to get late-time attractor when gravity is coupled to scalar field. Finally, in order to predict the final evolution of the universe, we have also studied classical stability of the model. It is found that there are late time attractors which are both locally as well as classically stable and so our model can realise the late time cosmic acceleration.

description: We give a complete characterization of pseudovarieties of semigroups whose finitely generated relatively free profinite semigroups are equidivisible. Besides the pseudovarieties of completely simple semigroups, they are precisely the pseudovarieties that are closed under Mal'cev product on the left by the pseudovariety of locally trivial semigroups. A further characterization which turns out to be instrumental is as the non-completely simple pseudovarieties that are closed under two-sided Karnofsky-Rhodes expansion.

description: Attribute based knowledge transfer has proven very successful in visual object analysis and learning previously unseen classes. However, the common approach learns and transfers attributes without taking into consideration the embedded structure between the categories in the source set. Such information provides important cues on the intra-attribute variations. We propose to capture these variations in a hierarchical model that expands the knowledge source with additional abstraction levels of attributes. We also provide a novel transfer approach that can choose the appropriate attributes to be shared with an unseen class. We evaluate our approach on three public datasets: aPascal, Animals with Attributes and CUB-200-2011 Birds. The experiments demonstrate the effectiveness of our model with significant improvement over state-of-the-art.

description: Recently, learning Chinese as foreign language is getting more popular at high schools in Berlin. The early form of after-school activity is being replaced by the formal module of elective subject for beginner as well as the advanced course of higher classes. Therefore, the question how to include Chinese in the final exams ("Abitur") becomes more than ever an important topic and experimental issue. According to this situation, this paper at first explains the current guidelines, testing formats and special features of the standardized written exam for graduates in the area of Berlin, then moves on to analyse both the oral test as well as the presentation examination and their designs. It discusses the standards of all the tests, their practical purpose and feasibility and provides suggestions for the future development.

description: We have implemented vibronic dynamics for simulations of the third order coherent response of electronic dimers. In the present communication we provide the full and detailed description of the dynamical model, recently used for simulations of chlorophyll-carotenoid dyads, terylene dimers, or hypericin. We allow for explicit vibronic level structure, by including selected vibrational modes into a "system". Bath dynamics include the Landau-Teller vibrational relaxation, electronic dephasing, and nonlinear vibronic (to bath) coupling. Simulations combine effects of transport and dephasing between vibronic levels. Transport is described by master equation within secular approximation, phase is accumulated in cumulants and its calculation follows the transport pathways during waiting time period.

description: This thesis presents how the authors organize the methodologies of their first Mandarin Chinese lesson for beginners over the age of puberty in German speaking countries. The objective of this lesson is to lay a foundation of knowledge on the target language by giving a big picture of important features and elements of Mandarin Chinese with their teaching philosophies integrated with Whole Language Approach, Accelerated Learning and Suggestopedia, and Schema Theory of Cognitive Psychology. Since "Whole to part" is a principle of "Whole Language Approach," the authors start their lessons with important information about the target language — Mandarin Chinese. Their students’ mother tongue is used to help them to get the understanding of the target language. The authors believe that this can reduce the difficulties in the process of learning Mandarin Chinese. The whole lesson is divided into three sections: mind mapping the characteristics of Mandarin Chinese, teaching Hanyu pinyin, and introducing the formation of Chinese characters. The information given in the mind map includes Word Order, Inflection, Articles, Pro-Drop, Tones, and Characters, will be a great help to their students in the future. The example sentences and the activity after mind mapping can help their students understand the differences between Mandarin and German. When the students learn from the mind map that there is no conjugation in Mandarin, their former negative impression of learning Chinese will change because the grammar of Mandarin is relatively simpler than German. The second section is to teach Hanyu pinyin on the basis of students’ existing knowledge. The teaching plan is based on the principle of "meaning" of Whole Language Approach and Communicative Approach. The authors firstly use numbers from 1 to 10, then eighteen action verbs with Total Physical Response, and lastly flash cards of pictures of real objects to teach the pronunciation system of Mandarin in pinyin. The last section is to introduce the 4 ways of creating Chinese characters: pictographs, self-explanatory, associative compounds, and pictophonetic. The goal of this section is to help students understand that the strokes of Chinese characters are meaningful lines and this basic knowledge can help them remember Chinese characters in an easier way.

To investigate the binding energy by the Kondo effect, we introduce the mean-field approach for the bound state of the $\bar{D}$, $B$ meson in charm/bottom nuclei. Assuming a simple model, we examine the validity of the mean-field approximation by comparing the results with the exact solutions. We also estimate the effect of the quantum fluctuation beyond the mean-field approximation. We discuss the competition between the Kondo effect and the other correlations in valence nucleon, the isospin symmetry breaking and the nucleon pairings.

Expone la importancia de la generación, desarrollo y fortalecimiento del pensamiento lógico matemático de los escolares del grado quinto, debido a la situación problemática presentada por los bajos niveles de desarrollo del pensamiento matemático dentro de la Institución Educativa y la desconexión de las competencias matemáticas con los entornos reales de desarrollo de los escolares. Por lo que, la investigación desarrolla una serie de secuencias didácticas que buscan el desarrollo y fortalecimiento del pensamiento lógico-matemático dentro de los contextos reales de participación económica de las familias en cuanto a la producción del café en el municipio debido a que éste pertenece a una región predominantemente productora de café, para que, a partir de allí, los escolares logren identificar y plantear soluciones a problemas reales del diario vivir, generando hipótesis tendientes a dar soluciones a situaciones problemáticas presentadas, utilizando un lenguaje matemático acorde a cada situación. La investigación se desarrolla bajo los presupuestos cualitativos teniendo la Investigación Basada en Diseño como el enfoque metodológico más acorde en cuanto a la naturaleza del problema expuesto, lo que permitió el logro sistemático de los objetivos propuestos. La secuencia didáctica se desarrolló en la plataforma TOMI y se incluyó en el dispositivo digital TOMi 7, sin embargo, la situación atípica presentada por la emergencia sanitaria generada por el virus del COVID-19 impidió el uso completo del dispositivo TOMi- 7.

The becoming of online healthcare through entangled power and performativity
Creators: name: Visser, Laura
name: DAVIES, OLIVIA ELISE
Publisher: name: Monash University
Year: 2023

description: In this article we adopt Barad’s theory of agential realism to explore how power and performativity aresimultaneously processual and ontologically entangled. We use the hyphenated term power-performativityto mobilize an exploration of how power is not an ‘outcome’ or ‘effect’ of, but an inseparable flow within, theprocesses of performativity through which the world is continuously becoming. This moves us beyond thetraditional, anthropocentric take on the relationship between power and performativity which emphasizeshuman agency and linear cause-effect, toward an alternative understanding of organizational phenomena asalways enacted through myriad intra-acting more-than-human actants. To empirically mobilize this approach,we explore power-performativity within online healthcare, enacted through personal online healthcarecommunities (POHCs). We explore multiple ‘diffraction gratings’ through which particular outcomes ofonline healthcare come to matter, while others are prevented from mattering. In doing so, we posit thesuitability of Barad’s agential realism for further explorations of the dynamics of power and performativity inmodes of organizing and organizational life and offer tools for how these may be done.

description: We present a new representation of harmonic sounds that linearizes the dynamics of pitch and spectral envelope, while remaining stable to deformations in the time-frequency plane. It is an instance of the scattering transform, a generic operator which cascades wavelet convolutions and modulus nonlinearities. It is derived from the pitch spiral, in that convolutions are successively performed in time, log-frequency, and octave index. We give a closed-form approximation of spiral scattering coefficients for a nonstationary generalization of the harmonic source-filter model.

Impact of initial models and variable accretion rates on the pre-main-sequence evolution of massive and intermediate-mass stars and the early evolution of HII regions

description: Massive star formation requires the accretion of gas at high rate while the star is already bright. Its actual luminosity depends sensitively on the stellar structure. We compute pre-main-sequence tracks for massive and intermediate-mass stars with variable accretion rates and study the evolution of stellar radius, effective temperature and ionizing luminosity, starting at $2\,M_\odot$ with convective or radiative structures. The radiative case shows a much stronger swelling of the protostar for high accretion rates than the convective case. For radiative structures, the star is very sensitive to the accretion rate and reacts quickly to accretion bursts, leading to considerable changes in photospheric properties on timescales as short as 100 - 1000 yr. The evolution for convective structures is much less influenced by the instantaneous accretion rate, and produces a monotonically increasing ionizing flux that can be many orders of magnitude smaller than in the radiative case. For massive stars, it results in a delay of the HII region expansion by up to 10,000 yr. In the radiative case, the HII region can potentially be engulfed by the star during the swelling, which never happens in the convective case. We conclude that the early stellar structure has a large impact on the radiative feedback during the pre-main-sequence evolution of massive protostars and introduces an important uncertainty that should be taken into account. Because of their lower effective temperatures, our convective models may hint at a solution to an observed discrepancy between the luminosity distribution functions of massive young stellar objects and compact HII regions.

description: Forests play a central role in our ecosystem and have a major influence on our climate, biodiversity, and quality of life. According to the Forest Condition Report, only one in five trees is currently considered healthy. Climate change and environmental stressors like heat and drought challenge forests globally, making protection and adaptation essential. Digital technologies offer new opportunities for sustainable forest management, with real-world labs (RWLs) playing a key role. RWLs allow to test innovative solutions in real environments and foster collaboration between scientists, policymakers, businesses and the public. In the form of a case study, we employ an RWL approach for digitization in forestry, which uses IoT sensors to monitor forests and collect data. Transdisciplinary workshops bring together diverse stakeholders to discuss these technologies and co-create solutions. This paper summarizes the RWL experiences in this context, summarizing results and experiences.

description: We introduce quantum correlations measures based on the minimal change in unified entropies induced by local rank-one projective measurements, divided by a factor that depends on the generalized purity of the system in the case of non-additive entropies. In this way, we overcome the issue of the artificial increasing of the value of quantum correlations measures based on non-additive entropies when an uncorrelated ancilla is appended to the system without changing the computability of our entropic correlations measures with respect to the previous ones. Moreover, we recover as limiting cases the quantum correlations measures based on von Neumann and Rényi entropies (i.e., additive entropies), for which the adjustment factor becomes trivial. In addition, we distinguish between total and semiquantum correlations and obtain some relations between them. Finally, we obtain analytical expressions of the entropic correlations measures for typical quantum bipartite systems.

description: We proceed to study Yang-Baxter deformations of 4D Minkowski spacetime based on a conformal embedding. We first revisit a Melvin background and argue a Lax pair by adopting a simple replacement law invented in 1509.00173. This argument enables us to deduce a general expression of Lax pair. Then the anticipated Lax pair is shown to work for arbitrary classical $r$-matrices with Poincaé generators. As other examples, we present Lax pairs for pp-wave backgrounds, the Hashimoto-Sethi background, the Spradlin-Takayanagi-Volovich background.

RISIS Research Seminar: What can explain the socio-economic gap in international student mobility uptake? Similarities between Germany, Hungary, Italy, and the UK

intergovernmental policies

description: International student mobility (ISM) prepares young people for the challenges of global and multicultural environments. However, disadvantaged students have lower participation rates in mobility schemes and, hence, benefit less from their positive impacts on career progression. Therefore, policymakers aim to make mobility programs more inclusive. Nevertheless, it is far from clear how policy design can achieve this aim. This study investigates factors driving inequality in international student mobility uptake. The study’s novelty is twofold: first, in contrast to most existing studies it does not only investigate individual but also university characteristics as possible drivers of unequal uptake. This is possible due to the use of rich graduate survey and administrative data merged with university-level European Tertiary Education Register (ETER) data. Second, the study compares results across four European countries. Results show that the socio-economic mobility gap remains still sizable even when taking university characteristics into account. However, universities matter considerably and especially student compositions in terms of socio-economic background and ability contribute to unequal ISM uptake. As a consequence, intergovernmental policies should aim to distribute grants and mobility opportunities more equally across all universities, independent of their student composition.

description: The activity of sows after farrowing significantly influences the occurrence of crushing losses. For this reason, sow activity is often quantified in scientific research through video analysis. To improve practicality, this study developed an automated approach based on the YOLOv10 object detection framework, addressing the big data challenge. The core idea of this approach was to calculate an activity score based on the number of postural changes. Therefore, the model detects the sow’s posture for each frame in the videos. The raw data from the model is then filtered, and the number of postural changes is calculated, from which an activity score is derived for each video. For comparison with a human-generated activity assessment, the videos were finally categorized into three classes based on the activity score. The final performance evaluation across activity classes shows an accuracy of 0.945. Based on these results, it can be concluded that this approach provides an automated alternative to manual video analysis for determining sow activity.
Magnetic polarization of Ir in underdoped, non-superconducting Eu(Fe$_{0.94}$Ir$_{0.06}$)$_{2}$As$_{2}$

description: Using polarized neutron diffraction and x-ray resonant magnetic scattering (XRMS) techniques, multiple phase transitions were revealed in an underdoped, non-superconducting Eu(Fe$_{1-x}$Ir$_{x}$)$_{2}$As$_{2}$ ($\mathit{x}$ = 0.06) single crystal. Compared with the parent compound EuFe$_{2}$As$_{2}$, the tetragonal-to-orthorhombic structural phase transition and the antiferromagnetic order of the Fe$^{2+}$ moments are significantly suppressed to $\mathit{T_{S}}$ = 111 (2) K and $\mathit{T_{N,Fe}}$= 85 (2) K by 6% Ir doping, respectively. In addition, the Eu$^{2+}$ spins order within the $\mathit{ab}$ plane in the A-type antiferromagnetic structure similar to the parent compound. However, the order temperature is evidently suppressed to $\mathit{T_{N,Eu}}$= 16.0 (5) K by Ir doping. Most strikingly, the XRMS measurements at the Ir $\mathit{L_{3}}$ edge demonstrates that the Ir 5$\mathit{d}$ states are also magnetically polarized, with the same propagation vector as the magnetic order of Fe. With $\mathit{T_{N,Ir}}$ = 12.0 (5) K, they feature a much lower onset temperature compared with $\mathit{T_{N,Fe}}$. Our observation suggests that the magnetism of the Eu sublattice has a considerable effect on the magnetic nature of the 5$\mathit{d}$ Ir dopant atoms and there exists a possible interplay between the localized Eu$^{2+}$ moments and the conduction $\mathit{d}$-electrons on the FeAs layers.
