THE EFFECT OF LEARNING EXPERIENCES ON INTEREST IN STEM CAREERS: A STRUCTURAL EQUATION MODEL

Learning experiences can affect students' interest in STEM (science, technology, engineering, and mathematics) careers. Applying the social cognitive career theory, this study tested and compared the effect size and effect mechanism of formal learning experiences (FLE) and informal learning experiences (ILE) on 1133 tenth-grade students' interest in STEM careers (ISC) through a paper questionnaire survey. The results of structural equation model analysis showed that: 1) The total effect of ILE on students' ISC is much greater than that of FLE; 2) ILE, STEM self-efficacy (SSE) and STEM careers perceptions (SCP) can directly affect students' ISC; FLE and ILE can also indirectly affect students' ISC through the mediating role of SSE and SCP. The analyses suggest that in order to improve students' ISC, STEM education (especially informal STEM education) should be strengthened, both formal and informal education should pay attention to the cultivation of students' SSE and SCP. Keywords: interest in STEM careers, learning experiences, social cognitive career theory, STEM careers perceptions, STEM self-efficacy, structural equation model
Preparation and characterization of oleogels with tallow and partially hydrolyzed tallow as organogelators;Preparación y caracterización de oleogeles con sebo y sebo parcialmente hidrolizado como organogeladores

Preparación y caracterización de oleogeles con sebo y sebo parcialmente hidrolizado como organogeladores. El objetivo de este estudio fue evaluar el potencial de la organogelación de grasa de sebo (GS) y grasa de sebo parcialmente hidrolizada (GSH) contra monoglicéridos saturados (MG) y mezcla de monoglicéridos + diglicéridos saturados (MDG) como organogelantes. Con la propia GS se creó un oleogel con un nivel de adición del 30%, mientras que los oleogeles de GSH, MG y MDG se prepararon con niveles de adición del 10%. Los datos de composiciones de ácidos grasos mostraron que el oleogel de GSH (OGSH) era bastante similar a los oleogeles de MG y MDG. El contenido de grasa sólida, la acidez grasa libre y los valores de peróxido se encuentran en rangos aceptables para OGSH. También se evaluaron las propiedades térmicas, la morfología del cristal y los patrones de difracción de rayos X. Los análisis reológicos indicaron que todos los oleogeles tenían un módulo de almacenamiento (G ́) mayor que el módulo de pérdida (G ́ ́). La prueba de barrido de tiempo mostró que después de aplicar velocidades de cizallamiento más altas, los geles se reformaron en reposo. Además, todos los oleogeles protegieron su consistencia gelificada hasta alrededor de 54 °C de temperatura. Los resultados han sugerido que GSH podría ser un organogelador barato, eficiente, de fusión aguda, seguro y fácilmente disponible.
PAC-Bayes Analysis with Stochastic Kernels

We focus on a stochastic learning model where the learner observes a ﬁnite set of training examples and the output of the learning process is a data-dependent distribution over a space of hypotheses. The learned data-dependent distribution is then used to make randomized predictions, and the high-level theme addressed here is guaranteeing the learner’s performance on examples that were not seen during training, i.e. generalization. In this setting the unknown quantity of interest is the expected risk of the data-dependent randomized predictor, for which upper bounds can be derived via a PAC-Bayes analysis, leading to PAC-Bayes bounds. Speciﬁcally, we present a general form of the PAC-Bayes inequality, from which one may derive extensions of various known PAC-Bayes bounds as well as novel bounds. We clarify the role of the requirement of ﬁxed ‘data-free’ priors and discuss the use of data-dependent priors. We also discuss a simple PAC-Bayes bound that is valid for loss functions with unbounded range. Our analysis clariﬁes that those two requirements are used to bound an exponential moment, while the general PAC-Bayes inequality remains valid with those restrictions removed.

Tumors in this critical anatomical site are prone to develop local recurrence, and this occurs at a high level even in low-risk tumors. Previous studies found that high-risk was the most common category in rectal gastrointestinal stromal tumors (RGISTs), and size was the most important factor affecting the long-term prognosis. We aimed to find out the most influential factor on clinical outcomes, and describe demographics, oncological differences, and surgical procedures in patients with poor prognosis. Patients and Methods: Data on consecutive patients with RGIST, who were diagnosed at Peking University People’s Hospital, Shandong Province Hospital, and The First Affiliated Hospital of Shandong First Medical University from 2010 to 2020, were retrospectively evaluated. Further, a literature search was conducted by retrieving data from PubMed, EMBASE, and the Cochrane Library databases from inception up to March 20, 2020. Results: In all, 50 patients were diagnosed with RGIST at three medical centers, and 86 published records were finally included in the literature review. Combined analysis of the whole individual patient data showed that 5.5 cm was deemed an appropriate cut-off value for L-RGIST, and that patients usually showed a male predominance (67.59%), younger age at onset (56.61 years), higher operative difficulty, and poorer prognosis. Conclusion: Separation of patients with large RGIST from general patients may contribute to the recognition of the oncological characteristics and clinical management of this rare type of tumor.

Structural Reforms and Productivity Growth in Developing Countries: Intra- or Inter-Reallocation Channel?

This paper investigates the effects of financial sector, product market, and trade reforms on labor productivity growth and its two components—the intra-sectoral (within) and inter-sectoral (between) components—in a sample of developing countries over 1975–2005. The paper finds that most of the past trade, product, and financial sector reforms have increased the growth rate of labor productivity. In particular, countries that are further away from the technology leader tend to benefit more from structural reforms than countries closer to the technology frontier. Looking at the subcomponents of labor productivity growth, the paper finds that structural reforms work mostly through the intra-allocative efficiency channel but not through the inter-allocative efficiency channel. The intra-sectoral component is the main driver of the impacts of reforms on labor productivity growth, with a contribution between 76 and 96 percent.
GROMOV – WITTEN INVARIANTS OF BLOWUPS

We prove the Abelian/non-Abelian Correspondence with bundles for target spaces that are partial flag bundles, combining and generalising results by Ciocan-Fontanine–Kim– Sabbah, Brown, and Oh. From this we deduce how genus-zero Gromov–Witten invariants change when a smooth projective variety X is blown up in a complete intersection defined by convex line bundles. In the case where the blow-up is Fano, our result gives closed-form expressions for certain genus-zero invariants of the blow-up in terms of invariants of X. We also give a reformulation of the Abelian/non-Abelian Correspondence in terms of Givental’s formalism, which may be of independent interest.
On the differences between BERT and MT encoder spaces and how to address them in translation tasks

Various studies show that pretrained language models such as BERT cannot straightforwardly replace encoders in neural machine translation despite their enormous success in other tasks. This is even more astonishing considering the similarities between the architectures. This paper sheds some light on the embedding spaces they create, using average cosine similarity, contextuality metrics and measures for representational similarity for comparison, revealing that BERT and NMT encoder representations look significantly different from one another. In order to address this issue, we propose a supervised transformation from one into the other using explicit alignment and fine-tuning. Our results demonstrate the need for such a transformation to improve the applicability of BERT in MT.

*These authors contributed equally to this work Background: This study assessed the clinical characteristics of gastrointestinal bleeding (GIB), obstruction (GIO), and perforation (GIP) in patients with primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL) and the influence on long-term survival. Methods: A retrospective analysis was performed of 148 patients with PGI-DLBCL admitted to Peking University First Hospital from August 1994 to May 2018. The clinical characteristics of GIB, GIO, and GIP before and after chemotherapy were recorded. The associated overall survival and progression-free survival were analyzed. Results: Among 148 patients, 56.8% had gastrointestinal complications (GICs), including GIB, GIO, GIP, and multiple complications, and 22.6% of them occurred after chemotherapy, mostly during the first 4 cycles. The most common clinical manifestations of patients with GICs were abdominal pain or discomfort (79.8%), hematemesis or melena (22.6%), and abnormal bowel habits (17.9%). Patients with Eastern Cooperative Oncology Group (ECOG) score ≥2, tumor mass ≥10 cm, or intestinal involvement had significantly higher risk of severe GICs as initial manifestations. Among 130 patients who received chemotherapy, B symptoms, tumor mass ≥10 cm, and Lugano stage (IIE, IV) strongly correlated with GICs after chemotherapy (P < 0.05). Rituximab did not increase the risk of GICs. GICs which occurred before or after chemotherapy reduced the objective response rate at the end of chemotherapy. The prognosis of patients was significantly worsened by GIP, GIB, or multiple complications after chemotherapy (P < 0.05). GIB at presentation or GIO before or after chemotherapy had no prognostic value (both P > 0.05). Conclusion: GICs adversely affect the quality of life, prolong the length of hospitalization, and shorten the long-term survival of patients with PGI-DLBCL.

However, knowledge of the magnitude and correlates of these risk factors is limited in Tanzania. This study aimed to fill this gap using data collected from RSFCs in Dar es Salaam, the largest city in Tanzania. Methodology: A cross-sectional study was carried out among 560 RSFCs in three districts of Dar es Salaam between July and September 2018. Information on socio-economic factors and demographics, behavioral risks, anthropometric and biochemical indicators was collected. Adjusted odds ratios (OR) and prevalence ratio (PR) with corresponding 95% confidence intervals (CI) were estimated using multivariable binary logistic and modified Poisson regression models, respectively. Results: On average, participants consumed 11 street food meals/week. The prevalence (95% CI) of cardio-metabolic risk factors was 63.9% (60.6–69.9%) for overweight/obesity, 42.5% (38.3–46.9%) for raised blood pressure, 13.5% (10.9–16.8%) for raised triglycerides and 6.6% (4.9–9.3%) for raised glucose levels. The correlates of overweight/obesity were female vs male sex (APR=1.3; 95% CI 1.2–1.5), age of 41–64 vs 25–40 years (APR=1.4; 95% CI 1.2–1.6), high vs low income (APR=1.2; 95% CI 1.04–1.3), being married/cohabiting vs other (APR=1.2; 95% CI 1.01–1.4) and family history of diabetes vs no family history (APR=1.2; 95% CI 1.01–1.3). Age 41–64 vs 25–40 years, was the only significant factor associated with raised blood pressure APR (95% CI) 2.2 (1.7–2.9) and raised glucose AOR (95% CI) 3.9 (1.5–10.5). Conclusion: Our study revealed that RSFCs are at risk of cardio-metabolic health problems, especially women, middle-aged people and those with higher incomes. Transdisciplinary studies to understand the drivers of street food consumption are needed in order to inform interventions to mitigate the risk of developing cardio-metabolic diseases. These interventions should target both street food vendors and their consumers.
Calcium-Sensing Receptor Antagonist NPS-2143 Inhibits Breast Cancer cell Proliferation, Migration and Invasion via Downregulation of p-ERK1/2, Bcl-2 and Integrin β1 and Induces Caspase 3/7 Activation

Purpose: Calcium-sensing receptor (CaSR) has been associated with breast cancer metastasis tothe bone. Targeting chemoattractant factors, such as calcium, that are released in response tobone resorption could prevent metastasis and induce apoptosis of cancer cells. In the presentstudy, we investigated the potential caspase 3/7 activation following treatment with a CaSRantagonist, NPS-2143, in breast cancer cells. In addition, the effects of NPS-2143 on breastcancer cell proliferation, migration and invasion were assessed. Methods: Colorimetric MTT assay was used to evaluate cell viability. Apo-one homogeneouscaspase-3/7 assay was used to measure caspase 3/7 activities in breast cancer cells. Cellmigration and invasion were assessed using scratch wound assay and matrigel invasionchambers, respectively. The protein expressions of p-ERK1/2, integrin β1 and Bcl-2 wereevaluated using western blotting. Results: Our study revealed that NPS-2143 significantly reduced cell proliferation with halfmaximal (50%) inhibitory concentration (IC50) values of 4.08 and 5.71 μM in MDA-MB-231 and MCF-7 cells, respectively. NPS-2143 induced caspase 3/7 activation in MDA-MB-231 breastcancer cells which was accompanied with a remarkable reduction in the expression of Bcl-2antiapoptotic protein. NPS-2143 suppressed migratory and invasive abilities of MDA-MB-231cells with a significant reduction in the expression of p-ERK1/2 and integrin β1 proteins. Conclusion: Our study confirms the ability NPS-2143 to suppress proliferative, migratory andinvasive effects of breast cancer cells which was accompanied by caspase 3/7 activation andsuggests the potential of NPS-2143 as a promising anti-cancer molecule in breast cancer.
MADIS VASSER Testing a Computational Theory of Brain Functioning with Virtual Reality

Over the past decade the free energy principle has been proposed as an unifying theory of brain functioning, stating that all adaptive biological systems try to minimize uncertainty. This principle has been implemented as a process theory, active inference, that lends itself to some counter-intuitive predictions that we aim to test experimentally using modern immersive virtual reality (VR) systems. While gaining insights about active inference, we also developed new understanding and learned about VR research. The dissertation begins with designing the overall experimental framework and discussing the limits of VR software and hardware solutions. Next, we cover a conducted study on attenuation of self-generated hand movements, validating both the theory and our chosen practical methodology through reaction time measurements. We then further refine our experiment to allow the study of higherorder effects such as contrast perception and self-rated confidence related to visual attenuation. Our results show great promise for using VR in neuroscience and confirm previous findings in the active inference framework literature. The thesis culminates with a review and assessment of the current wider field of psychological and neuroscientific immersive VR research and offers guidelines for future work.
