From the headwater to the delta: A synthesis of the basin-scale sediment load regime in the Changjiang River
No full textMany large rivers in the world delivers decreasing sediment loads to coastal oceans owing to reductions in sediment yield and disrupted sediment deliver. Understanding the sediment load regime is a prerequisite of sediment management and fluvial and deltaic ecosystem restoration. This work examines sediment load changes across the Changjiang River basin based on a long time series (1950–2017) of sediment load data stretching from the headwater to the delta. We find that the sediment loads have decreased progressively throughout the basin at multiple time scales. The sediment loads have decreased by ~96% and ~74% at the outlets of the upper basin and entire basin, respectively, in 2006–2017 compared to 1950–1985. The hydropower dams in the mainstem have become a dominant cause of the reduction, although downstream channel erosion causes moderate sediment load recovery. The basin-scale sediment connectivity has declined as the upper river is progressively dammed, the middle-lower river is leveed and river-lake interplay weakens. The middle-lower river has changed from a slight depositional to a severe erosional environment, from a sediment transport conduit to a new sediment source zone, and from a transport-limited to a supply-limited condition. These low-level sediment loads will likely persist in the future considering the cumulative dam trapping and depleted channel erosion. As a result, substantial hydro-morphological changes have occurred that affect the water supply, flood mitigation, and the aquatic ecosystem. The findings and lessons in this work can shed light on other large river systems subject to intensified human interference.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Coastal Engineerin
The Relationship Between Knowledge Level and Attitudes of Mothers of Toddlers Towards Visits to Posyandu In Janti Village, Tarik District, Sidoarjo
No full textOne of the objectives of the Posyandu program is to reduce nutritional problems. The rate of malnutrition in Sidoarjo Regency is 3.8%, at the Tarik Health Center it is 0.13%, and in Janti Village, it reaches 5.13%. Malnutrition negatively impacts toddler growth. In 2023, the visit rate of toddlers to Posyandu in Janti Village was low, at only 32.1% of the total number of toddlers in the village, resulting in suboptimal monitoring of their growth. One factor influencing mothers' visits to Posyandu is their knowledge and attitude.This research is an analytical observational study with a cross-sectional design, aiming to analyze the relationship between the knowledge and attitudes of mothers of toddlers towards visits to Posyandu in Janti Village, Tarik District, Sidoarjo. The population consisted of 224 mothers of toddlers, with a sample of 70 respondents selected randomly through random sampling. Data were collected through questionnaires on the knowledge and attitudes of mothers towards Posyandu, as well as attendance records at Posyandu, and analyzed using Chi-Square and Fisher's Exact tests.Most respondents were aged 25-34 years (72.9%), had completed high school education (50.5%), and were housewives (62.6%). They generally possessed good knowledge about Posyandu (68.6%) or adequate knowledge (31.4%). Regarding visitation, 64.3% were active and 35.7% were inactive. This suggests that positive knowledge and attitudes towards Posyandu significantly influence visitation rates, supported by statistically significant results with a p-value of 0.001 (≤ 0.05).There exists a relationship between the level of knowledge and attitudes of mothers towards visits to Posyandu
Rezension/Review/Mapitio: Yuning Shen. 2018. Transitivität und Verbvalenz im Swahili. [Transitivity and Verb Valence in Swahili/Uelekezi na Mpangilio wa Vitenzi katika Lugha ya Kiswahili]. Köln: Rüdiger Köppe, 104 pp., ISBN 978-3-89645-712-7.
No full textYuning Shen’s study deals with transitivity and verb valency in Kiswahili using a corpus-based approach. The author relates the methods used and results with previous studies dealing with the same topic, namely Whiteley (1968), Abdulaziz (1996) and Olejarnik (2005). He uses the meta-function-rank-matrix (MF/R) from Chinese to point out the fallacy of adopting such a matrix from one language and imposing it on another. Using the parts of speech annotation TreeTagger (Schmid 1994, 1995) to examine previous verb classifications, the author discusses the divergent use of concepts such as verb radicals, verb stems and verb bases as used in different theoretical approaches.Kitabu hiki cha Yuning Shen kinahusu uelekezi na mpangilio wa vitenzi katika lugha ya Kiswahili kwa kutumia mkabala wenye msingi wa kopasi ya kiisimu. Mwandishi anazihusisha mbinu zilizotumika na matokeo yake na kazi za utafiti zilizotangulia zilizoshughulikia mada hiyo yaani Whiteley (1968), Abdulaziz (1996), na Olejarnik (2005). Shen anatumia mkabala wa mpangilio wa viwango tofauti vya matumizi ya lugha (meta-function-rank-matrix, MF/R) iliyotumika kwa utafiti wa lugha ya Kichina kwa ajili ya kuonesha udhaifu wa mkabala huo kwani unaiga mfumo unaofanya kazi katika lugha moja na kuutumia kwa lugha nyingine bila kuzingatia kuwa lugha ni tofauti. Kwa kutumia njia ya matawi ya kutenganisha vipashio vya maneno (TreeTagger) iliyobuniwa na Schmid (1994, 1995) kwa lengo la kuchunguza njia za awali za kuainisha vitenzi, mwandishi anayajadili matumizi yanayotofautiana ya dhana mbalimbali kama vile viini vya vitenzi, mashina ya vitenzi, na mizizi ya vitenzi jinsi ambavyo zimetumika katika mikabala mbalimbali ya kinadharia
Enterprise architecture modeling for cybersecurity analysis in critical infrastructures — A systematic literature review
No full textAs digital landscapes become increasingly complex, safeguarding sensitive information and systems against cyber threats has become a paramount concern for organizations. This paper provides a comprehensive review of how enterprise architecture modeling is used in the context of cybersecurity assessment, particularly focusing on critical infrastructures. The use of enterprise architecture models for cybersecurity is motivated by the main purpose of enterprise architecture, namely to represent and manage business and IT assets and their interdependence. While enterprise architecture modeling originally served to assess Business/IT alignment, they are increasingly used to assess the cybersecurity of the enterprise. The research questions explored include the types of enterprise architecture models used for cybersecurity assessment, how security aspects are incorporated into these models, the theoretical frameworks and reference theories applied, the research methods used for evaluation, and the strengths and limitations of these models in supporting cybersecurity assessment. This review encompasses research papers published before 2024, focusing on high-quality research from peer-reviewed journals and reputable conferences, thereby providing a structured and comprehensive overview of the current state of research in this domain.CC BY-NC 4.0Corresponding author: Yuning JiangE-mail addresses: [email protected]</p
Quantum Control of Interacting Spins
No full textQuantum decoherence is one of the most substantial challenges on the way to fullyfledged quantum technology. Noise mitigation based on dynamical control techniques, aside from error correction, is known to be another effective approach to protect qubits from decoherence. In this thesis, we studied the dynamics of a spin qubit interacting with a disordered spin bath in different dimensions. By modeling the environmental spins from fundamental dipolar couplings and employing Monte-Carlo simulations, this research provides an insight into the precise driving and control of a noisy spin qubit, including the noise distribution, decoherence mechanism, driving error, gate fidelity, and performance of dynamical decoupling sequence. This knowledge will be helpful to the future design of noise-robust quantum gates and potential decoupling protocols of spin qubits.https://github.com/Neuromancer43/SpinControl.jl Software PackageApplied Physic
Foreign Language Teachers' Beliefs and Practices in Language Education: What to Teach and How to Teach
No full textThis dissertation is a combination of two manuscripts. By using autoethnography in manuscript one, this study first reflects on my learning English as a foreign language journey and the influences that brought to my life. The seven stories in this study cover many aspects of foreign language education, including teaching contents, teaching methods, and teacher preparation. Through the lens of autoethnography, I will further explore factors that influence foreign language education. Through detailed analysis, I discover language learning is not isolated. Foreign language teaching and learning will be influenced by economy, politics, cultures, and society. Based on these findings, I ask many thought-provoking questions on foreign language education, such as teaching contents and teaching methods.
Manuscript two is traditional qualitative research using ethnographic methods. I use in-depth interviews to explore teachers' beliefs and practices of one supervisor and three foreign language teachers. I first present findings on their beliefs and practices in foreign language teaching and learning, including changes and challenges in the division's language education and foreign language teachers' beliefs and practices and their alignment with the ACTFL Standards. I will also use the ACTFL Standards as a lens to analyze how their beliefs and practices match with the 5Cs: Communication, cultures, connections, comparisons, communities. Finally, I will provide suggestions for future similar studies.Doctor of PhilosophyThis dissertation is a combination of two manuscripts.

A micro graphene high temperature sensor with a single Si<sub>3</sub>N<sub>4</sub> protective layer
No full textTemperature sensors are widely used in industrial production, national defense and military fields. The traditional temperature sensors normally operate in a limited temperature range no more than 200 °C, which cannot be used for extreme high temperature detections. In this paper, a thermal protection method for the sensing graphene membrane is proposed and a graphene high temperature sensor has been fabricated and investigated. By growing a single silicon nitride (Si3N4) protective layer on top of graphene, our design not only solves the problem that graphene is easily oxidized at high temperature, but also prevents graphene from being polluted by impurities, which would lead to the degradation of graphene performance. We further explore the protective effect of Si3N4 layer with different thicknesses on the performance of the sensor. It has been found that the 400 nm Si3N4 protective layer gives the best protective capability. The sensor exhibits a positive temperature coefficient (PTC) from 50 to 600 °C and a maximal temperature coefficient of resistance (TCR) value of 0.29% °C−1 at 150 °C is achieved. It has been demonstrated that our graphene high temperature sensor with protective layer structure maintains good stability not only at high temperature up to 600 °C, but also over a long-period of time under room temperature. In short, the high temperature sensor possesses a wide temperature measurement range with micro dimensions, a relatively high TCR and a smaller thermal hysteresis. The thermal protection approach proposed in this paper provides a new idea for the fabrication of high temperature pressure sensor, which is expected to be applied in aerospace engines and oil wells, etc.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic Components, Technology and Material
Assessing Measurement Invariance and Latent Mean Differences with Bifactor Multidimensional Data in Structural Equation Modeling
No full textabstract: Investigation of measurement invariance (MI) commonly assumes correct specification of dimensionality across multiple groups. Although research shows that violation of the dimensionality assumption can cause bias in model parameter estimation for single-group analyses, little research on this issue has been conducted for multiple-group analyses. This study explored the effects of mismatch in dimensionality between data and analysis models with multiple-group analyses at the population and sample levels. Datasets were generated using a bifactor model with different factor structures and were analyzed with bifactor and single-factor models to assess misspecification effects on assessments of MI and latent mean differences. As baseline models, the bifactor models fit data well and had minimal bias in latent mean estimation. However, the low convergence rates of fitting bifactor models to data with complex structures and small sample sizes caused concern. On the other hand, effects of fitting the misspecified single-factor models on the assessments of MI and latent means differed by the bifactor structures underlying data. For data following one general factor and one group factor affecting a small set of indicators, the effects of ignoring the group factor in analysis models on the tests of MI and latent mean differences were mild. In contrast, for data following one general factor and several group factors, oversimplifications of analysis models can lead to inaccurate conclusions regarding MI assessment and latent mean estimation.Dissertation/ThesisDoctoral Dissertation Educational Psychology 201
