description: Criatividade é um tema de pesquisa que vem crescendo de maneira significativa nos últimos anos. Desenvolver a criatividade é uma meta que tem sido buscada, especialmente na atualidade, por sistemas educacionais ao redor do mundo. Diante de mudanças constantes, para atender as demandas da contemporaneidade é necessário desenvolver essa habilidade tão importante. Por isso, o papel da escola é fundamental, trabalhando a criatividade e o pensamento crítico a fim de preparar pessoas para os desafios do século XXI. O objetivo deste trabalho foi realizar uma revisão integrativa sobre Criatividade na área de educação. Para isso foram acessadas as bases de dados Education Resources Information Center (ERIC), Periódicos Capes e Scielo, utilizando método integrado com os seguintes descritores Creativity AND Education, no período de 2018 a 2023, nos idiomas: inglês, português e espanhol.  Foi utilizada a metodologia PRISMA® para a revisão integrativa. A partir da coleta de dados foram encontrados 111 artigos, e após os critérios de exclusão foram incluídos 12 estudos para análise qualitativa. Os resultados apontaram que a maioria dos professores reconhecem a importância da criatividade na educação, embora enfrentem desafios ao implementar estratégias que estimulem a imaginação e inovação e preparem os alunos para as demandas do século XXI.

Thriving on sustainable development: sustainable autopoietic organisations
Creators: name: Hans Robert, von
Publisher: name: University of Westminster
Year: 2013

description: This doctoral thesis theorises on how business organisations have reacted to the legal principle of Sustainable Development. The proposition is that Sustainable Development is an event-driven principle of becoming where the present depends both on the organisation’s environment and its internal operations. The starting point of the research is the observing of decisions made in relation to Sustainable Development covering a period of around ten years. This is based on four distinctions resulting in a structural, processual, motivational and functional understanding of the organisations in question. The theoretical framework is based on Niklas Luhmann’s theory of social systems, emphasising his theory of organisations, contributing new knowledge on how organisations react to their environment, the consequence of a-centricity, poly-contexturality and the un- steerability of society. Firstly, the thesis demonstrates that, for the companies involved, Sustainable Development has resulted in a better use of resources, both natural and human and consequently capital. Secondly, the result cannot be attributed only to internal industry decisions but significantly also to the direct or indirect involvement of NGOs and other irritants. Thirdly, Sustainable Development can be highly attributed to law but when the environment of law is not satisfied, rules of behaviour outside the legal framework are created by organisations such as NGOs. The research shows that Sustainable Development is not a recipe for success in itself but, without it, long-term profit is not possible. There is a structural coupling between NGOs, businesses and legislators and this can be seen in the way they communicate with each other. It is clear that although relevant, law is not the only mechanism and, in some cases, not even the best. Rather than forcing businesses into a specific legal framework the best available solution, consistent with theory and application, is for business organisations to reduce difference between themselves and their environment through self-steering when it comes to Sustainable Development and to increase difference when it comes to organisational differentiation.

We demonstrate that within this model, it is possible to design a new type of blended algorithm for the task of privately computing the head of a search log. This blended approach provides significant improvements in the utility of obtained data compared to related work while providing users with their desired privacy guarantees. Specifically, on two large search click data sets, comprising 1.75 and 16 GB respectively, our approach attains NDCG values exceeding 95% across a range of privacy budget values.

Subjects: Cognitive Preparedness, Self-Defense, Anticipatory Strategies, Psychological Resilience.

description: Abstract

The landscape of self-defense predominantly emphasizes physical tactics, often overlooking the mental foundation upon which these actions rest. This paper delves deep into the role of mental preparedness in self-defense, asserting that cognitive and emotional readiness are fundamental to the effective application of self-defense mechanisms. Through a proposed psychological framework, we explore the critical components of anticipatory strategies, emphasizing the importance of awareness, decision-making capabilities, psychological resilience, and stress management. By illustrating the symbiotic relationship between mental preparedness and physical actions, this paper underscores the need for a comprehensive approach to personal safety.

Year: 2023

description: The Spectral Energy Distribution (SED) of galaxies in the mm-to-cm spectral window is the result of emission from cold dust grains, free-free, and synchrotron radiation. A multi-wavelength coverage of this range allows to disentangle the different contribution of these components, offering the possibility to investigate on the validity of current dust models and to estimate the star-formation rate without being affected by extinction. Yet, the mm-to-cm SED of galaxies is poorly known: I will discuss a case for exploring it with the instruments soon to be available at the Sardinia Radio Telescope, and present the results of a pilot SRT program to search for the Anomalous Microwave Emission, supposedly due to dust, in nearby galaxies.

description: This study explored differences among older adults in mental health by sexual minority status. Data came from the 2021 U.S. National Health Interview Survey. The study sample included older adults (or those aged ≥50 years, N = 15,559), and of those, two percent (n = 380) self-identified as lesbian, gay, or bisexual (LGB). Older LGB adults had significantly higher odds of reporting a diagnosis of depression and anxiety and experiencing serious psychological distress than older non-LGB adults. Additionally, older LGB adults reported higher odds of experiencing depression and anxiety more frequently than older non-LGB adults. Significant covariates included age, sex, housing, food security, and social support. Increased risk for mental illness may be long-term consequences of stigma and discrimination that this population has experienced over the life course. The combination of structural interventions and affirming mental healthcare that recognizes the cumulative negative experience among older LGB adults is necessary to achieve mental health equity.
title: British collaborative support to tackle SOC and criminal activities: A case study of the GAIN Network
Creators: name: Silvestri, C
Publisher: name: Liverpool John Moores University
Year: 2023

description: Based on a case study of the UK’s Government Agency Intelligence Network (GAIN), the research evaluated the organisational and operational risks and benefits of a novel commitment to intelligence sharing and the impact of the new arrangements on the agencies that make up the Network. It answered the question: In the modern era, the police no longer have monopoly control of crime-fighting; therefore, to what extent does British policing engage with partners to prevent and detect serious organised crime? A case study of the GAIN network A systematic literature review was undertaken, and a case study approach was employed. The former focused on globalisation and its relationship with transnational organised crime; the social factors that led to the creation of support agencies in response to that phenomenon, and how relationships between actors are influenced during a mutual collaboration. Data was collected via a survey and a series of semi-structured interviews. In the light of the COVID-19 pandemic, the data collection strategy employed was modified to mitigate any risk to the health and/or safety of the research participants. The study found that the police still have almost complete control over crime-fighting policy and practice in the context of serious and organised crime. GAIN has delivered benefits for policing, but its benefits for policing’s partners are rather less obvious. Ostensibly, the multi-agency collaboration promotes intelligence sharing, disruption activity, and networking among police and other partners. There is some evidence of success in that regard, but largely that is confined to the mechanisms for collaboration that GAIN has established. The strong links that have been forged between partners and between individuals employed by those partners undoubtedly have strengthened those relationships and delivered individuals a greater understanding of the challenges that each other faces. That may bring advantages, in terms of increased outputs and greater efficiencies, in the longer run. However, there is little evidence today of the kinds of creativity or innovation that are likely to see the partnership develop in those ways. Essentially, the GAIN experience suggests that the police are doing what they always have done; leading and directing partnerships and limiting partners’ opportunities to influence the direction or gain meaningful control. Arguably, that means that goals remain too narrowly focused and opportunities to think about policing problems (in this case, serious and organised crime) in new ways are overlooked. The study has emphasised that the police institution needs to pay constant attention to environmental and social changes as they affect crime and criminal behaviour. Without the knowledge gained through that activity, the police’s ability to adapt their responses to serious and organised crime and/or to better harness the energies and endeavours of partners, is bound to be constrained.

An elementary rigorous proof of bulk-boundary correspondence in the generalized Su-Schrieffer-Heeger model

description: We generalize the Su-Schrieffer-Heeger (SSH) model with the inclusion of arbitrary long-range hopping amplitudes, providing a simple framework to investigate arbitrary adiabatic deformations that preserve the chiral symmetry upon the bulk energy bands with any arbitrary winding numbers. Using only elementary techniques of solving linear difference equations and applying Cauchy's integral formula, we obtain a mathematically rigorous and physically transparent proof of the bulk-boundary correspondence for the generalized SSH model. The multiplicity of robust zero-energy edge modes is shown to be identical to the winding number. On the other hand, nonzero-energy edge modes, if any, are shown to be unstable under adiabatic deformations and not related to the topological invariant. Furthermore, under deformations of small spatial disorder, the zero-energy edge modes remain robust.

Compaction, scale and proximity: an investigation into the spatial implications of density for the design of new urban housing
Creators: name: Harper, Claire
Publisher: name: University of Westminster
Year: 2013

description: This thesis investigates the implications of density for the design of new urban housing. An historical study of the notion of density in architectural and planning practice indicates that density ratios as a design mechanism were born out of a desire to control the physical conglomeration of the built mass of the city and to limit the social and hygienic consequences of proximity between people. Density ratios therefore provided a device for addressing the societal distaste for the conditions of proximity, and a professional aversion to the cohesiveness and impermeability of the industrial city. A number of studies have investigated the correlation between density ratios and built form and found density in numeric terms to be a poor descriptor of the qualities of the built environment. However, it is argued that the numerical conception of density as a ratio measure is only one way in which density can be conceptualised and excludes the qualitative aspects of proximity and cohesiveness from the debate. The thesis presents a critique of the current definition of density as a ratio measure and sets out an alternative, spatial index of density that reintroduces the notions of proximity and cohesiveness to the conceptualisation of what density means for the design of the built environment. It proposes that the continued conception of density as a numeric index limits its veracity for describing the qualities and characteristics of the built environment, and perpetuates the need for assumptions and generalisations about the type of development associated with different density ratios. The index is proposed initially out of an historical analysis and a cross-disciplinary review used to gather together the range of research and understanding, types of measuring, applying, thinking about and writing about the subject of density in architecture and other disciplines. The proposed index is then tested against a series of typical housing schemes in East London. The index is presented finally as a reference for designers and provides a way of thinking about the social and spatial implications of proximity as a starting point for the design of new urban housing.

description: We solve Einstein vacuum equations in a spacetime region up to the "center" of gravitational collapse. Within this region, we construct a sequence of marginally outer trapped surfaces (MOTS) with areas going to zero. These MOTS form a marginally outer trapped tube (apparent horizon). It emerges from a point and is smooth (except at that point) and spacelike. In the proof we employ a scale critical trapped surface formation criterion established by An and Luk and a new type of quasilinear elliptic equation is studied. The main conclusion of this paper proves a conjecture of Ashtekar on black hole thermodynamics. And the spacetimes constructed here could also be viewed as (non-spherically symmetric) generalizations of the well-known Vaidya spacetime.

description: In this paper, we consider one--parameter ($λ>0$) families of Liénard differential equations. We are concerned with the study on the asymptotic behavior of periodic solutions for small and large values of $λ>0$. To prove our main result we use the relaxation oscillation theory and a topological version of the averaging theory. More specifically, the first one is appropriate for studying the periodic solutions for large values of $λ$ and the second one for small values of $λ$. In particular, our hypotheses allow us to establish a link between these two theories.

Cold molecular gas and nuclear activity in radio galaxies: Linking properties on macro and micro scales
Creators: name: Torresi, Eleonora
Publisher: name: Zenodo
Year: 2023

description: Cross-population radio galaxies (FRII-LERG, i.e., powerful radio sources with an inefficient engine) are a powerful tool to investigate the long-standing relation between accretion and ejection. Indeed, they break the classical one-to-one correspondence between accretion mode and radio morphology by separating the effects of optical and radio classifications. To shed light on the nature of FRII-LERG, we present a comparative study of the X-ray and CO properties of a sample of nearly a hundred sources classified in the radio (FRI/FRII) and optical (HERG/LERG) bands. X-rays probe the AGN's innermost regions (sub-pc scale) and allow us to estimate the accretion rate free from contamination effects accurately. CO emission lines represent the best tracer of the molecular ISM, considered a fuel for AGN activity. This systematic and uniform study will help us verify if FRII-LERG are evolved sources, i.e., they now miss the cold fueling material that made them shine in the past
title: The Use of Maxillary Sinus Imaging as a Tool in Human Identification
Creators: name: Runge, T
Publisher: name: Liverpool John Moores University
Year: 2023

description: The presented research performs evaluations of maxillary sinus morphologies for human identification purpose. Due to the durability of maxillary sinuses, morphological analyses of the structure can prove to be extremely valuable and informative, even when parts of the skull are destroyed and dental records cannot be applied. This research is comprised of 4 studies evaluating maxillary sinus morphologies in order to build a comprehensive outlook on the methodological potentials. In total the used sample is comprised of right and left maxillary sinuses from 988 individuals divided into 12 populations. The morphologies are assessed by extracting the maxillary sinuses from radiographic and CT images and applying elliptic Fourier analyses on the structures. Morphological variability is investigated by converting the maxillary sinus morphology into multiple closed curves, and embedding them into a cartesian system. Principal component analyses on four components further simplifies the processing. The first two studies of this research are concerned with morphological uniqueness testing both in a simulated and real-life scenario to lay a comprehensive foundation for method applicability. Uniqueness testing is executed as a morphological ante- and postmortem comparison by calculating Euclidean and Mahalanobis distances. Euclidean correlation values from 0.000 in the simulated sample up to 0.002 in the real-life sample indicate maxillary sinus morphological uniqueness for each ante- and postmortem sinus morphology pair. Mahalanobis distances are used for visualisation. The third study is assessing the reproducibility of maxillary sinus morphological extraction by applying Cohen’s kappa values. The high kappa values in intra- and inter-observer reliability testing indicate high quality extraction and interpretation of morphologies, increasing the methodological confidence level. Finally, the last study is dedicated to understanding age-related changes in maxillary sinuses by calculating growth rates by population and by sex on Euclidean distances. All evaluations reveal quasi-linear and monotonously rising distances with growth rates varying among left and right sinuses and population. This research advances the potential of maxillary sinus morphologies for human identification and demonstrates its advantages over other paranasal identification methodologies. Therefore, this research acts as an essential first step toward using the proposed methodological framework in future forensic casework.
title: Performance of the Athletic Ability Assessment in Adolescent Academy Football players

description: LTAD models suggest boys aged 12-16 years should focus on strength, power, speed, agility, and sport-specific skill development. Consequently, implementing movement quality training interventions with football players around PHV will lessen the effects of adolescent awkwardness. Therefore, the aim of this thesis was to a) Assess the intra- and inter-rater reliability of the AAA and its scoring methods among academy football populations and b) explore the effects of maturation on AMC in academy youth footballers, using the AAA. The participants were part of a Category 1 football academy and aged U12-16 during the 2020-21 season. Each movement of the AAA was completed for a total of five repetitions in frontal and sagittal planes on both left and right leg, which were marked using video footage. In study one the intra-rater reliability, was assessed by the lead researcher assessing 59 participants, with a test-retest conducted after 7 days. To determine the inter-tester reliability of the AAA scores, five other testers scored all participants from the video footage. In study two each movement was scored across three areas using a three-point scale. Each specific area was associated to a numeric value, to objectify the athletes movement competency. Each key area score was summated to produce a single total movement score ranging from 3 to 9. The results from study one showed that the AAA is a reliable assessment tool to be used within English football academies. The inter-rater reliability was 0.975, whereas the intra-rater reliability in this study was substantial (0.714). The results from study two, showed that AAA performance of the Double Lunge, SL RDL and hop and stick improves with biological maturity, thus is most likely due to increases in strength which occur during male adolescence. However, the circa- groups were significantly worse at performing the OH squat.
title: A study on 4.1 proteins in brain.

description: The 4.1 family consists of a multi-functional group of proteins expressed from four distinct genes. 4.1R, 4.IN, 4.1G and 4.IB have distinct mammalian tissue and developmental expression patterns and each protein exists as multiple isoforms produced by alternative splicing of their respective genes. Functions as diverse as signalling, regulation of pre-mRNA splicing, mitotic spindle rearrangements and anchoring of membrane proteins have been suggested for these proteins based on their tissue and subcellular distribution and the protein binding partners identified. 4.1R was the first family member to be discovered and was identified as a component of the erythrocyte membrane skeleton important for the integrity of these cells. The role of 4.1 proteins in the brain is of particular interest. All four proteins are expressed but each has a distinct regional localisation. Limited information is available on the subcellular distribution of 4.1 proteins in brain and other tissues. To begin to address this issue, the complement of 4.1 protein isotypes was investigated in postsynaptic density (PSD) fractions of mammalian forebrain. 4.1R was shown to be expressed predominantly in cell bodies and dendrites of primary rat midbrain cultures supporting a postsynaptic distribution for this 4.1 gene product. Antibodies specific to 4.1R, 4. IN and 4.1G and an antibody recognising 4.1R, G and B localised all four 4.1 proteins in PSD fractions. Of these, two 4.IB isoforms (4.1B150kDa and 4.1Bl26kDa) were most abundant while the single 4.1R isoform identified (4.1R80kDa) was most highly enriched. To investigate the postsynaptic binding activities of 4.1R, recombinant 4.1R CTerminal Region (4.1R-CTR) was produced and shown to mimic characteristic spectrin-actin binding and digestion properties of native 4.1R. One and two dimensional gel overlay analysis indicated binding of 4.1R-CTR with dynamin, actin and the intermediate filament proteins a-internexin and NF-L. The identity of actin, ainternexin and NF-L was confirmed using protein specific antibodies. These interactions were supported by data from 4.1R-CTR affinity chromatography but the insolubility of PSDs made it difficult to study 4.1R-CTR-PSD protein interactions under native conditions. Localisation of 4.1 at PSDs provides evidence supporting a role for these proteins at specialised membrane domains. This is consistent with the localisation of the Drosophila homologue of 4.1 (coracle) to septate junctions and the recently identified interaction of mammalian 4.1R with the tight junction protein ZO-2. The interaction of 4.1R-CTR with a-internexin and NF-L indicates a structural role for 4.1R at PSDs. The interaction with actin could in turn suggest a function for 4.1R in the dynamic morphological changes that accompany neuronal plasticity and is consistent with the role 4.1R plays in erythrocyte membrane deformation. The data presented gives further insights into the workings and architecture of PSDs and proposes novel interactions for the C-terminal region of 4.1R.

description: We present a rigorous convergence result for the smooth solutions to a singular semilinear hyperbolic approximation, a vector BGK model, to the solutions to the incompressible Navier-Stokes equations in Sobolev spaces. Our proof is based on the use of a constant right symmetrizer, weighted with respect to the parameter of the singular pertubation system. This symmetrizer provides a conservative-dissipative form for the system and this allow us to perform uniform energy estimates and to get the convergence by compactness.

description: The concept of ensemble learning offers a promising avenue in learning from data streams under complex environments because it addresses the bias and variance dilemma better than its single model counterpart and features a reconfigurable structure, which is well suited to the given context. While various extensions of ensemble learning for mining non-stationary data streams can be found in the literature, most of them are crafted under a static base classifier and revisits preceding samples in the sliding window for a retraining step. This feature causes computationally prohibitive complexity and is not flexible enough to cope with rapidly changing environments. Their complexities are often demanding because it involves a large collection of offline classifiers due to the absence of structural complexities reduction mechanisms and lack of an online feature selection mechanism. A novel evolving ensemble classifier, namely Parsimonious Ensemble pENsemble, is proposed in this paper. pENsemble differs from existing architectures in the fact that it is built upon an evolving classifier from data streams, termed Parsimonious Classifier pClass. pENsemble is equipped by an ensemble pruning mechanism, which estimates a localized generalization error of a base classifier. A dynamic online feature selection scenario is integrated into the pENsemble. This method allows for dynamic selection and deselection of input features on the fly. pENsemble adopts a dynamic ensemble structure to output a final classification decision where it features a novel drift detection scenario to grow the ensemble structure. The efficacy of the pENsemble has been numerically demonstrated through rigorous numerical studies with dynamic and evolving data streams where it delivers the most encouraging performance in attaining a tradeoff between accuracy and complexity.

description: Galactoglucomannan (GGM) is the predominant hemicellulose in coniferous trees, such as Norway spruce, and has been used as a multipurpose emulsifier in the food industry. In vitro digestion with a cellular antioxidant activity assay was performed to determine the bioaccessibility and antioxidant activity of phenolic compounds, and the behaviour of GGM on in vivo experimental assay against induced colon cancer. The results showed that digestion decreased the bioaccessibility and antioxidant capacity of phenolic compounds. Cellular analysis did not support these findings once an antioxidant effect was observed in human cell lines. GGM attenuated the initiation and progression of colon cancer, by reducing the foci of aberrant crypts in rats, and modified the intestinal bacterial microbiota (disrupting the balance between Firmicutes and Bacteroidetes phyla). Thus, GGM provided chemopreventive protection against the development of colon cancer and acted as an intracellular antioxidant agent.

description: Hadronic jets in deeply inelastic electron-proton collisions are produced by the scattering of a parton from the proton with the virtual gauge boson mediating the interaction. The HERA experiments have performed precision measurements of inclusive single jet production and di-jet production in the Breit frame, which provide important constraints on the strong coupling constant and on parton distributions in the proton. We describe the calculation of the next-to-next-to-leading order (NNLO) QCD corrections to these processes, and assess their size and impact. A detailed comparison with data from the H1 and ZEUS experiments highlights that inclusive single jet production displays a better perturbative convergence than di-jet production. We also observe that the event selection cuts in some of the di-jet measurements of both H1 and ZEUS induce an infrared sensitivity that destabilises the perturbative stability of the predictions. Our results open up new opportunities for QCD precision studies with jet production observables in deep inelastic scattering.

description: The ARBURG freeformer represents an additive manufacturing system for producing thermoplastic components using commercially available polymer granulate. This fabrication process offers the potential to use feedstocks known from the metal injection molding (MIM) sector to manufacture so-called green parts. These parts consist of 60 Vol.-% stainless steel powder and 40 Vol-% organic polymer binding system. By debinding and sintering these green parts, it is possible to economically produce full metal components with mechanical properties comparable to metal injection molding. In this publication, the process of producing stainless steel parts with ARBURG plastic freeforming will be presented. The mechanical properties and part density are optimized by varying manufacturing parameters and raw materials. Furthermore, concepts to optimize and increase the service life of the nozzle are shown and discussed. An increase of at least 250% could be achieved by plasma nitriding and coating components of the discharge system.
