description: We consider the d-dimensional Boussinesq system defined on a sufficiently smooth bounded domain, and subject to a pair $\{ v, \boldsymbol{u} \}$ of controls localized on $\{ \widetildeΓ, ω\}$. Here, $v$ is a scalar Dirichlet boundary control for the thermal equation, acting on an arbitrary small connected portion $\widetildeΓ$ of the boundary $Γ= \partial Ω$. Instead, $\boldsymbol{u}$ is a $d$-dimensional internal control for the fluid equation acting on an arbitrary small collar $ω$ supported by $\widetildeΓ$ (Fig 1). The initial conditions for both fluid and heat equations are taken of low regularity. We then seek to uniformly stabilize such Boussinesq system in the vicinity of an unstable equilibrium pair, in the critical setting of correspondingly low regularity spaces, by means of an explicitly constructed, finite dimensional feedback control pair $\{ v, \boldsymbol{u} \}$ localized on $\{ \widetildeΓ, ω\}$. In addition, they will be minimal in number, and of reduced dimension: more precisely, $\boldsymbol{u}$ will be of dimension $(d-1)$, to include necessarily its $d$\textsuperscript{th} component, and $v$ will be of dimension $1$. The resulting space of well-posedness and stabilization is a suitable, tight Besov space for the fluid velocity component (close to $\boldsymbol{L}^3(Ω$) for $ d = 3 $) and a corresponding Besov space for the thermal component, $ q > d $. Unique continuation inverse theorems for suitably over determined adjoint static problems play a critical role in the constructive solution. Their proof rests on Carleman-type estimates, a topic pioneered by M. V. Klibanov since the early 80's, after the 1939- breakthrough publication \cite{Car}.

description: The aim of this thesis is to give a contribution to the research on Bankruptcy Law between 1883 and 1903, a period marked by two important legal reforms: the Italian Commercial Code and the law of composition with creditors. In particular, the paper explores companies default (that is, limited liability companies and cooperative societies) declared by the Court of Milan in this period. The choice to focus on these specific bankrupts is due to the growing economic importance that the Milanese area took at the end of nineteenth century, becoming one of the main economic districts. The reconstruction of bankruptcy events is made by means of an analysis of both legal historiography and magazines, as well as of archive groups of Archivio di Stato di Milano and of Archivio Storico della Camera di Commercio di Milano. The companies default is observed from a legal and historical point of view in order to understand the evolution of the Italian Corporate Insolvency Law in the twentieth century.

description: O Direito do Trabalho nacional tem, nos últimos anosconhecido uma especial dinâmica ou, se preferirmos, um permanente movimentoreformador, tendente à introdução de uma maior flexibilidade no mercado detrabalho que é, assiduamente defendido como excessivamente rígido. Anecessidade deste movimento reformador justifica-se, entre outros aspectos, comas profundas alterações verificadas no xadrez económico mundial, palco em quePortugal parece encontrar-se em progressiva perda de protagonismo. Por outrolado, o pedido de assistência financeira solicitado em Abril de 2011 pelogoverno português junto das instituições internacionais parece ter desencadeado uma ntensificação deste movimento reformador. É justamente neste quadro quevêm sendo introduzidas sucessivas reformas na legislação laboral visandoconferir-lhe uma maior flexibilidade. Entre tais dispositivos normativos,contam-se a Lei n.º 53/2011, de 14 de Outubro, que veio estabelecer um novoregime de compensação nas várias modalidades de cessação de contratos detrabalho celebrados após Novembro de 2011, a Lei n.º 23/2012, de 25 de Junho,que introduziu uma nova fórmula de cálculo das indemnizações por cessação docontrato de trabalho e, por fim, a Lei n.º 69/2013, de 30 de Agosto de 2013,que altera o Código de Trabalho, bem como os diplomas anteriormente referidos -Lei n.º 53/2011, de 14 de Outubro, e Lei n.º 23/2012, de 25 de Junho de 2012.Adicionalmente, deve ainda ser referida a entrada em vigor da Lei n.º 3/2012,de 10 de Janeiro, a qual aprova o regime extraordinário dos contratos a termocelebrados no âmbito do Código do Trabalho. No trabalho que ora se apresenta,procurámos encetar uma análise partindo do Regime do Contrato de Trabalho aTermo Resolutivo, inscrito no Código de Trabalho de 2009, cruzando-o com asmais autorizadas reflexões presentes entre a doutrina, bem como com as decisõesditadas pela jurisprudência dos tribunais superiores, não esquecendo,naturalmente, as contínuas alterações normativas introduzidas pelo legisladorno ordenamento jurídico, às quais já acima, sumariamente, nos reportámos.

description: This doctoral thesis aims to approach to the process of European integration, from the perspectives of Communication Sciences, in conjunction with the history of the Europe and the European Union, seeking its further framing within the phenomenon generally known as the "information society". The research is divided into three main parts, from which the eight chapters that comprise it develop. Thus, the first two parts aim to present and discuss the nuclear issues that we have followed in the work (European Union and Information Society), which merge in a third part, where they are analytically crossed. A presente Tese de Doutoramento procura abordar o processo de construção europeia, a partir das Ciências da Comunicação, em articulação com a História da Europa e da União Europeia, procurando o seu enquadramento no fenómenogenericamente conhecido por "sociedade da informação". A investigação estrutura-se em três partes principais, a partir das quais se desenvolvem os oito capítulos que a compõem. Assim, as duas primeiras partes visam apesentar e problematizar detalhadamente o reduto nuclear das questões centrais que nos acompanham neste trabalho (União Europeia e sociedade da informação), as quais se fundem, posteriormente, numa terceira, aí surgindo entrecruzadas.

Topology and sizing optimization of prismatic sandwich structures for marine vessels
Creators: name: Yan, Shengyu
Publisher: name: University of British Columbia
Year: 2022

description: Marine vessels need to improve in a number of different ways, which could potentially be fulfilled by using new, advanced structural components. Sandwich structures are currently not used in cargo vessels but can potentially offer improvements in terms of several structural features. Metallic sandwich structures are recyclable and could be incorporated within the surrounding structure usually made from metals. This research focuses on metallic sandwich structures with different core topologies whose natural frequency is maximized using topology and sizing optimization techniques. To connect sandwich structure to the surroundings, a joint connection is optimized using stress-based topology optimization (TO) and compared with previously proposed alternatives. Furthermore, metallic sandwich structures have very thin plates which are laser welded. Since the weld is thinner than the plates, this research investigates the consequence of weld geometrical variation on vibration. Homogenization methods including Solid Isotropic Material with Penalization (SIMP) method and Equivalent Single Layer (ESL) method are utilized to build simplified models and to accelerate computation. Based on the performed optimization, X-core and corrugated core sandwich topologies show the highest efficiency. Additionally, TO provides even better topologies at certain mass levels with non-periodic shapes. The proposed new joints by TO feature 2-3 times smaller maximum stress than the previously proposed joint, even at lower structural weight. Furthermore, weld geometry plays a very important role in the response of laser welded web-core sandwich panels. Weld characteristics should be considered in design and production to ensure the desired natural frequency.

description: 1959 veröffentlicht Theodor W. Adorno einen kleinen Aufsatz, den er Theorie der Halbbildung titelt. Der Beitrag erntet wenig Zuneigung und Beachtung bildungswissenschaftlicher Kollegen und reiht sich nahtlos in die Serie verzweifelter „Nie wieder Auschwitz”-Kassandra-Rufe ein. Fünfundzwanzig Jahre nach seinem Tod wird die Theorie der Halbbildung „plötzlich” lebendig und rückt in den Mittelpunkt bildungswissenschaftlicher Diskurse. Dies dient als Anlass, ausgehend vom Humboldtschen Bildungsideal und Adornoscher Bildungsaporie die Theorie der Halbbildung zu rekonstruieren und ihre Rezeptionsgeschichte nachzuzeichnen um zeitgenössische bildungswissenschaftliche Relevanz herauszuarbeiten. Dabei zeigt sich, das eine Abgrenzung in klassisch-Adornosche und zeitgenössisch-neue Halbbildung sinnvoll scheint.

description: Ransomware has become an increasingly popular type of malware across the past decade and continues to rise in popularity due to its high profitability. Organisations and enterprises have become prime targets for ransomware as they are more likely to succumb to ransom demands as part of operating expenses to counter the cost incurred from downtime. Despite the prevalence of ransomware as a threat towards organisations, there is very little information outlining how ransomware affects Windows Server environments, and particularly its proprietary domain services such as Active Directory. Hence, we aim to increase the cyber situational awareness of organisations and corporations that utilise these environments. Dynamic analysis was performed using three ransomware variants to uncover how crypto-ransomware affects Windows Server-specific services and processes. Our work outlines the practical investigation undertaken as WannaCry, TeslaCrypt, and Jigsaw were acquired and tested against several domain services. The findings showed that none of the three variants stopped the processes and decidedly left all domain services untouched. However, although the services remained operational, they became uniquely dysfunctional as ransomware encrypted the files pertaining to those services

description: Selective binding of metal ions to their receptors at the cell membranes is essential for immune reactions, signaling, and opening/closing of the ion channels. Such ligand‐binding‐based pore activities inspire scientists to build metal‐ion‐responsive mesoporous films that can interact with metal ions to tune the ionic nanopore transport. However, to apply these mesoporous films in novel sensing and separation applications, their ligand‐binding‐triggered ionic pore transport needs to be understood fundamentally toward programming the transport of both anions and cations simultaneously and gradually. Herein, it is shown how Ca²⁺ ion concentration and attachment to the different chemistry silica nanopores tunes finely the nanopore transport of both anions and cations, especially for phosphate‐containing polyelectrolyte (PMEP) functionalized mesopores. This biased ligand binding can gradually regulate the transport of anions and cations, whereas pores without polymers can gradually regulate only the anionic transport. Last, pore polymer functionality related to Ca²⁺ ion binding also diverts the pores’ adsorption/desorption (reversibility) response. Almost fully reversible Ca²⁺ binding is observed in non‐functional pores and non‐reversible Ca²⁺ binding at the PMEP‐modified pores. It is also demonstrated that non/functional pores, even at sub‐µm concentrations, bind only divalent Ca²⁺ ions, but they are not selective to trivalent Al³⁺ ions.

description: Brassica vegetables contain glucosinolates, which are well-known for their potential to form health-promoting isothiocyanates. Among those crucifers, white and red cabbage are commonly consumed vegetables, exhibiting different glucosinolate and hydrolysis profiles thereof. Regarding the health beneficial effects from these vegetables, more information, especially concerning the seasonal variation of glucosinolate profiles and the formation of their bioactive hydrolysis products in commercial cabbages, is needed. In this study, glucosinolates and glucosinolate hydrolysis product profiles in red and white cabbages from three different food retailers were monitored over six different sampling dates across the selling season in autumn. For the first time, it was shown that, while glucosinolate profiles were similar in each cabbage variety, glucosinolate hydrolysis product profiles and hydrolysis behavior varied considerably over the season. The highest total isothiocyanate concentrations were observed in conventional red (1.66 μmol/g FW) and organic white (0.93 μmol/g FW) cabbages purchased at the first sampling date in September. Here, red cabbage was with up to 1.06 μmol/g FW of 4-(methylsulfinyl)butyl isothiocyanate (sulforaphane), an excellent source for this health-promoting isothiocyanate. Cabbages purchased 11 weeks later in autumn released lower levels of isothiocyanates, but mainly nitriles and epithionitriles. The results indicate that commercial cabbages purchased in early autumn could be healthier options than those purchased later in the year.

Volvidos alguns milénios é a própria memória humana que adquire um suporte externo: a tecnologia escrita. Séculos decorridos, a tarefa de copiar as obras escritas haveria de se “mecanizar”, por via da prensa de tipos móveis. O século XIX trouxe consigo o telégrafo eléctrico e a possibilidade de transmitir mensagens à distância de forma quase instantânea. No segundo quartel do século XX, os computadores electrónicos haveriam de revolucionar os processos de cálculo e processamento da informação. Finalmente, a Internet proporcionou, em termos teóricos, a democratização no acesso à informação pelas massas.

Dynamic, particle-based simulation of industrial handling and draping process of textile semi-finished products
Creators: name: Nazemi, Amir
Publisher: name: University of British Columbia
Year: 2023

description: The superior strength-to-weight ratio of woven fabric composites, along with their high formability, is one of the primary design parameters defining their increased applications in modern manufacturing processes, including aerospace and automotive. However, complex geometries of finished components continue to bring several challenges to designers as they need to cope with manufacturing defects with a minimal overhead cost. Wrinkling is a common defect in forming and handling semi-finished textile composites. This defect is due to weak bending stiffness of yarns in fabric preforms, causing an excessive relative motion between fibers during out-of-plane deformation. This challenge can be further exacerbated when using specialized blank holders in forming set-ups. For forming simulations of fabric composites, Finite Element (FE) method has been a longstanding means to predict and mitigate manufacturing defects. Such simulations are predominately intended to not only predict the onset, growth, and shape of wrinkles, but also determine the best processing conditions that can yield an optimized positioning of fibers upon forming. However, small-time step requirements in explicit FE codes, numerical instabilities, and large computational time are among some drawbacks of the current FE models in composites forming research, hindering their extensive use as fast and efficient digital twins in pertinent industries. This thesis presents a novel woven fabric simulation technique through a so-called material point method (MPM), which enables the use of much larger time steps along with fewer numerical instabilities, hence the ability to run significantly faster and yet efficient forming simulations. As a preliminary case study, both standard 2D deformation modes and 3D hemispherical forming setups are employed using a plain weave test material. The MPM results are compared to the conventional FE simulations, as well as to the physical experiments. Overall, the MPM method showed a runtime around 20 times faster than its FE counterpart in the present study, yet with comparable reliability in forming parameters predictions as verified by different metrics during experiments. Such a fast simulation tool is believed to have the potential to sizably enhance the development of emerging automated fiber handling and preform processes under the emerging AI-based smart manufacturing paradigm.

Les cours traitent partiellement de l’organisation spatiale de la classe, pourtant c’est la première chose à laquelle l’instituteur.trice est confronté.e quand il/elle débute une nouvelle année scolaire. Nous avions alors pour objectif de traiter ce sujet, afin de l’approfondir et comprendre les différentes réflexions sous-jacentes. Nous cherchions à répondre à la question suivante : à quoi ressemble une classe idéale ? Pour ce faire, nous nous sommes intéressées aux représentations des élèves, des enseignant.es ainsi qu’aux propos des auteur.es à ce sujet, afin de les confronter. Nous avons alors demandé à un groupe d’enfants et d’enseignantes de dessiner et légender leur classe idéale. Il s’est avéré que les avis divergent. Cependant grâce à cette diversité, nous constatons que les pédagogues, les enseignant.es et les élèves ont une volonté conjointe d’aménager la classe en sous-espaces. Alors pourquoi les représentations s’écartent-elles de la classe réelle ? Les auteur.es révèlent que chaque espace revêt une fonction particulière ; des espaces représentent un soutien à la gestion de classe pour l’enseignant.e, certains peuvent être exploités de façon autonome par l’apprenant.e, d’autres encore apportent un développement intellectuel à ce dernier sans nécessité la présence d’un adulte. Par conséquent, ces apports théoriques, nous aide à traduire les besoins des enseignant.es et des élèves dans leurs dessins. Pourquoi les enseignant.es n’aménagent-ils/elles pas leur classe en fonction des besoins relevés dans les illustrations ? Nous avons aussi constaté que les représentations des enseignant.es sont particulièrement élaborées, pourtant leur classe effective ne répond pas à leurs attentes. Où se trouve la rupture entre la volonté et la mise en place de leur classe idéale ?
Pressure-induced concomitant topological and metal-insulator quantum phase transitions in Ce$_3$Pd$_3$Bi$_4$

description: The electronic property and magnetic susceptibility of Ce$_3$Pd$_3$Bi$_4$ were systemically investigated from 18 K to 290 K for varying values of cell-volume using dynamic mean-field theory coupled with density functional theory. By extrapolating to zero temperature, the ground state of Ce$_3$Pd$_3$Bi$_4$ at ambient pressure is found to be a correlated semimetal due to insufficient hybridization. Upon applying pressure, the hybridization strength increases and a crossover to Kondo insulator is observed at finite temperatures. The characteristic temperature signaling the formation of Kondo singlet, as well as the characteristic temperature associated with $f$-electron delocalization-localization change, simultaneously vanishes around a critical volume of 0.992$V_0$, suggesting that such metal-insulator transition is possibly associated with a quantum critical point. Finally, the Wilson's loop calculations indicate that the Kondo insulating side is topologically trivial, thus a topological transition also occurs across the quantum critical point.

description: The screen has become a constituent of the kinetic visual regime of modernity that is constantly producing an inter|face|world whose presence manifests itself as a totality in the quotidian horizon of events. On one hand, its mediation allows us an immediate access to the speed, laterality and superficiality of images permitting their accelerated movement to a gaze that processes them as shareable images-map: coded images whose decoding assure the immediate subjective recognition and orientation in the world he navigates. However this (auto)mobilization guaranteed by the sociotechnical screen, one of a telepresence, becomes also a paradoxical extatic (i)mobilization. In an inter|face|world one can no longer define clear separations. There are no borders such as subject/object or private/public. From new readings of Lacan (Perniola, 2006; Žižek, 2009; Nusselder, 2009), we also propose the concept of an image-libido that will allow us to describe the subjective immersion in a symbiotic inter|face. We’re now dealing with the libidinal power of an intimate non-shareable image that transforms us into desiring statue-men (Loureiro, 2007), hybrids of a never fulfilled identification.

description: For longer than one decade, liquid metal batteries (LMBs) are developed with the primary aim to provide economic stationary energy storage. Featuring two liquid metal electrodes separated by a molten salt electrolyte, LMBs operate at elevated temperature as simple concentration cells. Therefore, efficient mass transfer is a basic prerequisite for their economic operation. Understanding these mechanisms cannot be limited at the single layer level. With this motivation, the effects of solutal- and thermally-driven flow are studied, as well as the flow coupling between the three liquid layers of the cell. It is shown that solutal convection appears first and thermal convection much later. While the presence of solutal flow depends on the mode of operation (charge or discharge), the occurrence of thermal convection is dictated by the geometry (thickness of layers). The coupling of the flow phenomena between the layers is intriguing: while thermal convection is confined to its area of origin, i.e. the electrolyte, solutal convection is able to drive flow in the positive electrode and in the electrolyte.

description: To circumvent a mesh dependency of damage models, non‐local approaches such as phase‐field and gradient‐extended damage models have shown a good capability and attracted a lot of attention for modeling fracture. These models can predict crack nucleation, kinking, and branching. The gradient‐extended formulation proposed by [1, 2], which includes a micromorphic degree of freedom for damage, is connected to a phase‐field damage model presented in [3]; by connecting fracture parameters in brittle fracture. The latter is followed by comparing the thermodynamic consistency of these models. Despite having similarities in the formulation, gradient‐extended models differ from the standard phase‐field ones by having a damage threshold. Besides that, the local iteration exists in the gradient‐extended damage models. By employing the cohesive phase‐field model or the Angiotensin type 1 (AT1), a damage threshold appears in the formulation; by having a linear term for damage in the crack density function, see [4,5,12]. A comparison between these models is made, by taking several numerical examples and comparing their responses in a quasi‐static case. Moreover, the feasibility of different responses is addressed when one uses a standard Newton‐Raphson solver or the arc‐length one for solving a boundary value problem.

description: As already known by Rana's result \href{https://doi.org/10.1103/PhysRevA.87.054301}{[\pra {\bf87} (2013) 054301]}, all eigenvalues of any partial-transposed bipartite state fall within the closed interval $[-\frac12,1]$. In this note, we study a family of bipartite quantum states whose minimal eigenvalues of partial-transposed states being $-\frac12$. For a two-qubit system, we find that the minimal eigenvalue of its partial-transposed state is $-\frac12$ if and only if such two-qubit state must be maximally entangled. However this result does not hold in general for a two-qudit system when the dimensions of the underlying space are larger than two.

description: As an important application in remote sensing, landcover classification remains one of the most challenging tasks in very-high-resolution (VHR) image analysis. As the rapidly increasing number of Deep Learning (DL) based landcover methods and training strategies are claimed to be the state-of-the-art, the already fragmented technical landscape of landcover mapping methods has been further complicated. Although there exists a plethora of literature review work attempting to guide researchers in making an informed choice of landcover mapping methods, the articles either focus on the review of applications in a specific area or revolve around general deep learning models, which lack a systematic view of the ever advancing landcover mapping methods. In addition, issues related to training samples and model transferability have become more critical than ever in an era dominated by data-driven approaches, but these issues were addressed to a lesser extent in previous review articles regarding remote sensing classification. Therefore, in this paper, we present a systematic overview of existing methods by starting from learning methods and varying basic analysis units for landcover mapping tasks, to challenges and solutions on three aspects of scalability and transferability with a remote sensing classification focus including (1) sparsity and imbalance of data; (2) domain gaps across different geographical regions; and (3) multi-source and multi-view fusion. We discuss in detail each of these categorical methods and draw concluding remarks in these developments and recommend potential directions for the continued endeavor.

description: Two‐dimensional (2D) materials catalysts provide an atomic‐scale view on a fascinating arena for understanding the mechanism of electrocatalytic carbon dioxide reduction (CO₂ ECR). Here, we successfully exfoliated both layered and nonlayered ultra‐thin metal phosphorous trichalcogenides (MPCh₃) nanosheets via wet grinding exfoliation (WGE), and systematically investigated the mechanism of MPCh₃ as catalysts for CO₂ ECR. Unlike the layered CoPS₃ and NiPS₃ nanosheets, the active Sn atoms tend to be exposed on the surfaces of nonlayered SnPS₃ nanosheets. Correspondingly, the nonlayered SnPS₃ nanosheets exhibit clearly improved catalytic activity, showing formic acid selectivity up to 31.6 % with −7.51 mA cm⁻² at −0.65 V vs. RHE. The enhanced catalytic performance can be attributed to the formation of HCOO* via the first proton‐electron pair addition on the SnPS₃ surface. These results provide a new avenue to understand the novel CO₂ ECR mechanism of Sn‐based and MPCh₃‐based catalysts.

description: We study the monogamy and polygamy inequalities of quantum correlations in arbitrary dimensional multipartite quantum systems. We first derive the monogamy inequality of the $α$th ($0\leqα\leq\frac{r}{2}, r\geq2$) power of concurrence for any $2\otimes2\otimes2^{n-2}$ tripartite states and generalize it to the $n$-qubit quantum states. In addition to concurrence, we show that the monogamy relations are satisfied by other quantum correlation measures such as entanglement of formation. Moreover, the polygamy inequality of the $β$th ($β\leq0$) power of concurrence and the $β$th ($β\geq s, 0\leq s\leq1$) power of the negativity are presented for $2\otimes2\otimes2^{n-2}$. We then obtain the polygamy inequalities of quantum correlations for multipartite states. Finally, our results are shown to be tighter than previous studies using detailed examples.

description: Genetic diseases are a leading cause of death and disability worldwide with immense economic and societal burdens. However, currently fewer than 5% of genetic diseases have approved treatments, often with limited therapeutic benefit to patients. Genome editing provides a new therapeutic strategy to treat genetic diseases. In the last few years, the Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated protein 9 (CRISPR/Cas9) system has emerged as a promising gene editing approach due to its ease in design and flexibility to target different genetic diseases. One factor limiting its broader application is that it will introduce double-stranded deoxyribonucleic acid (DNA) breaks (DSBs). New advances in the CRISPR/Cas9 system are “base” and “prime” editing, which do not generate DSBs. Base editing has shown great potential to precisely repair the majority of pathogenic point mutations in the patient’s DNA. Prime editing, while currently less efficient, can introduce a broader range of possible edits. However, there remains a major challenge: delivery of genome editors to the affected tissues. To begin to address this challenge, two reporter gene mouse models were developed. Both models introduce a point mutation to knockout the reporter gene activity. Upon gene editing, the mutation is corrected back to the wildtype sequence, thereby restoring the reporter gene activity. The efficiency of gene editing can be visualized and measured with an in vivo whole animal imaging system, which permits repeated and long-term assessments of gene editing. To validate both mouse models, base editor mRNA and a mutation-specific single guide RNA (sgRNA) were encapsulated with lipid nanoparticles (LNPs) and intravenously administered into the reporter mice. This resulted in 83.5% restoration of wildtype reporter gene activity in the liver. One major application of these mouse models will be to evaluate and optimize gene editor delivery systems targeting various tissues. As an example, intramuscular administration of LNPs encapsulated with base editing components led to significant genome editing in the injected muscle, which could be readily visualized in the live imager. These novel reporter gene mouse models will provide critical tools for the in vivo evaluation and optimization of genome editor delivery and improved genome editor formulations.

description: Context: Evidence-based software engineering (EBSE) can be an effective resource to bridge the gap between academia and industry by balancing research of practical relevance and academic rigor. To achieve this, it seems necessary to investigate EBSE training and its benefits for the practice. Objective: We sought both to develop an EBSE training course for university students and to investigate what effects it has on the attitudes and behaviors of the trainees. Method: We conducted a longitudinal case study to study our EBSE course and its effects. For this, we collect data at the end of each EBSE course (2017, 2018, and 2019), and in two follow-up surveys (one after 7 months of finishing the last course, and a second after 21 months). Results: Our EBSE courses seem to have taught students adequately and consistently. Half of the respondents to the surveys report making use of the new skills from the course. The most-reported effects in both surveys indicated that EBSE concepts increase awareness of the value of research and evidence and EBSE methods improve information gathering skills. Conclusions: As suggested by research in other areas, training appears to play a key role in the adoption of evidence-based practice. Our results indicate that our training method provides an introduction to EBSE suitable for undergraduates. However, we believe it is necessary to continue investigating EBSE training and its impact on software engineering practice.

description: Ernährung ist einer der wichtigen Bereiche für die große Transformation. Doch wie kann eine Umstellung auf ein nachhaltiges Ernährungssystem gelingen? Der vorliegende Zukunftsimpuls setzt sich mit dieser Frage auseinander - basierend auf über zehn Jahren Forschung zu nachhaltiger Ernährung am Wuppertal Institut. Einen Schwerpunkt setzt das Papier auf die Außer-Haus-Gastronomie, denn bereits kleine Umstellungen - etwa in der Zutatenauswahl - haben hier große Wirkung. Mit geeigneten Rahmenbedingungen kann die Außer-Haus-Gastronomie den Konsumierenden als leicht zugänglicher Erlebnisort für nachhaltigere Ernährung dienen und gleichzeitig Landwirtinnen und Landwirten ein zuverlässiger Abnehmer für biodiversitätsschonende und klimafreundliche Lebensmittel sein. Doch für eine Transformation des Ernährungssystems sind auch andere Akteure gefragt: Der Zukunftsimpuls adressiert Politik, (Land-)Wirtschaft, Wissenschaft und jeden und jede Einzelne - denn die Transformation des Ernährungssystems ist eine gesamtgesellschaftliche Aufgabe.

description: Nous avons construit ce mémoire à la suite d’une réflexion que nous nous sommes faits sur l'enseignement de l’alimentation équilibrée que nous avons vécu lors de notre scolarité. Nous avons décidé de créer une séquence d’enseignement-apprentissage sur l’alimentation équilibrée qui avait pour objectifs principaux d’éviter toute forme de stigmatisation, un point qui était à améliorer selon nous avec nos souvenirs de notre passé d’élève, ainsi que la possibilité de permettre aux élèves de pouvoir s’autoréguler dans leurs choix alimentaires. Nous avons mis un point central sur les concepts de macronutriment et de calorie en les travaillant à partir d’exercices d’analyse et de classement comme la lecture des emballages d’aliments. Ensuite, les élèves ont créé un repas équilibré en se basant sur les concepts précédents, ont appris à lire la pyramide alimentaire et ont créé une nouvelle version qui permettrait de mieux se l’approprier. L’utilisation de l’application “MyFitnessPal”, qui consiste à enregistrer ses aliments pour effectuer le calcul des calories et la répartition des différents macronutriments, a permis de synthétiser toutes les notions apprises en classe et plonger les élèves dans une situation d’analyse concrète de leur quotidien. Cette séquence nous a permis de percevoir les différences entre les concepts quotidiens des élèves sur l’alimentation équilibrée et les concepts scientifiques qu’ils ont intégré tout au long de ce travail. Après avoir mené notre séquence, nous l’avons terminée par une évaluation sommative qui avait pour but de rendre compte des apprentissages effectués.

description: There is a lack of investigations assessing the performance of systemic inflammation indices as outcome predictive tools in African Americans with prostate cancer. This study aims to assess the relationships between neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation (SII), and systemic inflammation response index (SIRI) with survival outcomes among 680 diverse men with prostate cancer. Routine blood results were collected from self-identified African American and European American patients. We applied multivariable Cox regression modeling to examine the associations of systemic inflammation indices with overall and prostate cancer-specific survival. The median survival follow-up was 5.9 years, with 194 deaths. NLR, SII, and SIRI, but not PLR, showed associations with all-cause and prostate cancer-specific mortality when coded as dichotomized and continuous variables. NLR and SIRI were significantly associated with prostate cancer-specific mortalityamong all men (hazard ratio (HR) 2.56 for high vs. low NLR; HR 3.24 for high vs. low SIRI) and African American men (HR 2.96 for high vs. low NLR; HR 3.19 for high vs. low SIRI). Among European Americans, only SII showed an association with prostate cancer-specific survival. These observations suggest that inflammation indices merit further study as predictors of prostate cancer mortality.
