Perceived control and cortisol reactivity to acute stressors : variations by age, race and facets of control
Creators: name: Wen, Jin-Hui
Publisher: name: University of British Columbia
Year: 2020

description: Greater perceived control is associated with better health and well-being outcomes, possibly through more adaptive stress processes. Yet little research has examined whether global perceived control, as well as its facets of personal mastery and perceived constraints, predict psychological and physiological stress reactivity. Thus, the goal of the present study was to evaluate the associations of perceived control and its facets with changes in subjective stress and cortisol in response to acute laboratory stressors. In addition, we considered the moderating roles of age and race. In a sample of 735 U.S. adults ages 25–75 (71% White, 18% Black, 11% Other/Unknown Races), participants completed a measure of perceived control at baseline and subsequently underwent two lab-based acute stress tasks. Subjective stress and salivary cortisol were collected pre- and post-stressors. Perceived control was related to smaller increases in subjective stress, but did not directly predict cortisol responses. Age and race interacted to moderate the associations between facets of perceived control and stress reactivity. Specifically, greater personal mastery predicted lower subjective stress responses in White older adults, and higher perceived constraints predicted greater cortisol reactivity among White younger adults, whereas no association was found among racial minorities. These findings suggest that, among Whites, older adults garner the stress protective benefits of mastery and are buffered against the link between constraints and cortisol stress reactivity. Future research on the role of perceived control in stress and health should distinguish between facets of control as well as consider the importance of age and racial differences.

description: Strong lensing has developed into an important astrophysical tool for probing both cosmology and galaxies (their structure, formation, and evolution). Using the gravitational lensing theory and cluster mass distribution model, we try to collect a relatively complete observational data concerning the Hubble constant independent ratio between two angular diameter distances $D_{ds}/D_s$ from various large systematic gravitational lens surveys and lensing by galaxy clusters combined with X-ray observations, and check the possibility to use it in the future as complementary to other cosmological probes. On one hand, strongly gravitationally lensed quasar-galaxy systems create such a new opportunity by combining stellar kinematics (central velocity dispersion measurements) with lensing geometry (Einstein radius determination from position of images). We apply such a method to a combined gravitational lens data set including 70 data points from Sloan Lens ACS (SLACS) and Lens Structure and Dynamics survey (LSD). On the other hand, a new sample of 10 lensing galaxy clusters with redshifts ranging from 0.1 to 0.6 carefully selected from strong gravitational lensing systems with both X-ray satellite observations and optical giant luminous arcs, is also used to constrain three dark energy models ($Λ$CDM, constant $w$ and CPL) under a flat universe assumption. For the full sample ($n=80$) and the restricted sample ($n=46$) including 36 two-image lenses and 10 strong lensing arcs, we obtain relatively good fitting values of basic cosmological parameters, which generally agree with the results already known in the literature. This results encourages further development of this method and its use on larger samples obtained in the future.

description: Objective: We employed Mendelian randomization to explore the effects of genetic predisposition to type 2 diabetes (T2D), hyperglycemia, insulin resistance, and pancreatic β-cell dysfunction on risk of stroke subtypes and related cerebrovascular phenotypes. Methods: We selected instruments for genetic predisposition to T2D (74,124 cases, 824,006 controls), HbA1c levels (n = 421,923), fasting glucose levels (n = 133,010), insulin resistance (n = 108,557), and β-cell dysfunction (n = 16,378) based on published genome-wide association studies. Applying 2-sample Mendelian randomization, we examined associations with ischemic stroke (60,341 cases, 454,450 controls), intracerebral hemorrhage (1,545 cases, 1,481 controls), and ischemic stroke subtypes (large artery, cardioembolic, small vessel stroke), as well as with related phenotypes (carotid atherosclerosis, imaging markers of cerebral white matter integrity, and brain atrophy). Results: Genetic predisposition to T2D and higher HbA1c levels were associated with higher risk of any ischemic stroke, large artery stroke, and small vessel stroke. Similar associations were also noted for carotid atherosclerotic plaque, fractional anisotropy, a white matter disease marker, and markers of brain atrophy. We further found associations of genetic predisposition to insulin resistance with large artery and small vessel stroke, whereas predisposition to β-cell dysfunction was associated with small vessel stroke, intracerebral hemorrhage, lower gray matter volume, and total brain volume. Conclusion: sThis study supports causal effects of T2D and hyperglycemia on large artery and small vessel stroke. We show associations of genetically predicted insulin resistance and β-cell dysfunction with large artery and small vessel stroke that might have implications for antidiabetic treatments targeting these mechanisms.
Construction of Self-Dual Integral Normal Bases in Abelian Extensions of Finite and Local Fields

description: Let $F/E$ be a finite Galois extension of fields with abelian Galois group $Γ$. A self-dual normal basis for $F/E$ is a normal basis with the additional property that $Tr_{F/E}(g(x),h(x))=δ_{g,h}$ for $g,h\inΓ$. Bayer-Fluckiger and Lenstra have shown that when $char(E)\neq 2$, then $F$ admits a self-dual normal basis if and only if $[F:E]$ is odd. If $F/E$ is an extension of finite fields and $char(E)=2$, then $F$ admits a self-dual normal basis if and only if the exponent of $Γ$ is not divisible by $4$. In this paper we construct self-dual normal basis generators for finite extensions of finite fields whenever they exist. Now let $K$ be a finite extension of $\Q_p$, let $L/K$ be a finite abelian Galois extension of odd degree and let $\bo_L$ be the valuation ring of $L$. We define $A_{L/K}$ to be the unique fractional $\bo_L$-ideal with square equal to the inverse different of $L/K$. It is known that a self-dual integral normal basis exists for $A_{L/K}$ if and only if $L/K$ is weakly ramified. Assuming $p\neq 2$, we construct such bases whenever they exist.

description: Gli spazi possono armonizzare il benessere di sezione? Questa ricerca è stata sviluppata partendo da un bisogno importante dei bambini in una sezione di scuola dell’infanzia, scaturito dalla presenza di tante nuove frequenze. La ricerca è dedicata anche all’inclusione dei bambini di cultura e lingua diversa. Capita spesso di voler modificare degli spazi a casa, in ufficio, in camera da letto, poiché non rispecchiano la nostra personalità o sono scomodi per le nostre necessità, per questo avviene un cambiamento. Il lavoro di tesi indagherà sulla possibilità di sviluppare un’accoglienza nel gruppo, attraverso la rivisitazione degli spazi. Svolgendo un ruolo da protagonisti, i bambini hanno trovato degli accordi per sviluppare dei cambiamenti nella struttura interna della propria aula. È stata attuata un’analisi dei dati di tipo qualitativo, con l’aiuto di griglie osservative ho considerato dodici bambini scelti in funzione del loro recente inserimento in sezione e, grazie alla redazione del diario di bordo, ho avuto modo di prestare attenzione alle dinamiche di tutto il gruppo. Un’intervista con la docente accogliente ha inoltre offerto la possibilità di prendere in considerazione un punto di vista esterno. Questo progetto ha dimostrato che attraverso un’attenta predisposizione degli spazi e dei materiali si può favorire l’accoglienza, l’inclusione e incrementare la competenza collaborativa, sia durante il gioco libero sia nelle attività strutturate.

description: Neste artigo, leva-se a cabo uma reflexão crítica sobre o discurso e a prática da cidade criativa, sugerindo como alternativa a inovação social. O modo como se tem desenvolvido a experiência da Galeria de Arte Pública da Quinta do Mocho, em Loures, coloca em evidência algumas das principais diferenças entre as duas abordagens de transformação urbana, bem como alguns dos desafios que a inovação social enfrenta no decurso da sua materialização concreta. Num momento em que a lógica do urbanismo neoliberal se apropriou da criatividade, da cultura e das artes, tornando-as palavras-chave, torna-se importante demonstrar a existência de formas alternativas de mobilização da criatividade, através da arte pública, com vista a uma mudança sócio-espacial mais inclusiva, participada e justa.

Publisher: name: Medi@ções

description: A teoria do treino está suportada no conceito de periodização enquadrando o pla-neamento e a análise do treino. O problema é a falta de alternativas na perspectiva do treinador, devido à focalização nas referências fisiológicas. Assim pretende-se enquadrar o planeamento, com a qualidade das tarefas de práti-ca, e com o contexto competitivo, como forma alternativa à periodização, e quanti-ficação da carga de treino, baseadas em variáveis fisiológicas. Realizamos uma análise da bibliografia e observação direta da etapa World Surfing League de Pe-niche (2010 e 2015), para caracterizar o contexto competitivo, e caracterizamos o treino através do registo de ocorrências. Os surfistas fazem em média 11,2h de surf e 3,9h de condição física. O volume foi de 11,6 ondas com 41,7 manobras e a intensidade de 0,22 ondas/min e 3,6 manobras/onda. Na competição temos uma média de 8,3 ondas/bateria, com 3,6 manobras/onda e 5,4 pontos/onda, O planea-mento baseia-se nas tarefas de prática: aprendizagem das técnicas, ligações de manobras e rendimento na onda. O planeamento é efectuado em função do contexto competitivo e através das tare-fas de treino. As tarefas da condição física não são o cerne do treino e da periodi-zação, e não podem ser planeadas separadamente, porque são complementares ao surf.

description: Resumen Se analizó el efecto del Programa en los niveles de autoestima y ansiedad en per-sonas con diagnóstico de TMG. Participaron 30 personas, ?= 22 y ?= 8, entre 27 y 61 años (M=46.64). Se aprecian diferencias significativas (t(29)=-2,336, p=0,029) en el valor medio de la autoestima, entre ambos momentos. Al inicio del programa, mayores niveles de ansiedad se asociaron con niveles más bajos de autoestima (r=0,39, p=.030), pero esto no sucedió al final del programa. Por otro lado, niveles más bajos de ansiedad se asociaron con niveles más altos de autoes-tima al final del programa (r=-523; p=0,003). Finalmente, una mayor reducción de la ansiedad se asoció con mayores niveles de ansiedad en el inicio del programa (r=0,540, p=0,003). Palavras-clave: Autoestima, Ansiedad, TMG (Transtorno Mental Grave), Actividad Física, Deporte. Abstract The effect of the program on the levels of self-esteem and anxiety in people with TMG diagnoses was analyzed. Participated 30 persons, ?=22 and ?= 8, aged between 27 and 61 (M =46.64). There were significant differences (T(29 =-2,336; p=.029) in the mean value of self-esteem, between the two moments. At the be-ginning of the program, higher levels of anxiety were associated with lower self-esteem levels (r=.397; p=.030), but this did not occur at the end of the program. Lower levels of anxiety were associated with higher levels of final self-esteem (r -.523, p=.003). The greatest reduction in anxiety was associated with higher levels of anxiety at the beginning of the program (r=.540, p=.003). Key concepts: Self-esteem, Anxiety, TMG (Serious Mental Disorders), Physical Activity, Sport.

description: Using a functional renormalization group approach, we study interaction-driven instabilities in quadratic band crossing point two-orbital models in two dimensions, extending a previous study of Sun et al. [1]. The wavevector-dependence of the Bloch eigenvectors of the free Hamiltonian causes interesting instabilities toward spin nematic, quantum anomalous Hall and quantum spin Hall states. In contrast with other known examples of interaction-driven topological insulators, in the system studied here, the QSH state occurs at arbitrarily small interaction strength and for rather simple intra- and inter-orbital repulsions.

description: Multilayers of fullerenes with and without endohedral Ar units, C60 and Ar@C60, were investigated by photoemission and density functional theory. The stoichiometry and the endohedral nature of Ar is checked by x-ray photoelectron spectroscopy and x-ray photoelectron diffraction. Valence band ultraviolet photoemission spectra show a strong hybridisation of the Ar 3p valence shell with the 6T1u molecular orbital of C60. A hybridisation gap of 1.6 +/- 0.2 eV is found. This is in agreement with density functional theory (DFT) that predicts 1.47 eV, and indicates Ar@C60 to be a noble gas compound with a strong coupling between Ar and the C60 cage. No giant Ar photoemission cross section as predicted for the gas phase in [Phys. Rev. Lett. 99, 243003 (2007)] was found.

description: The transmission of ultrashort (7 fs) broadband laser pulses through periodic gold nano-structures is studied. The distribution of the transmitted light intensity over wavelength and angle shows an efficient coupling of the incident p-polarized light to two counter-propagating surface plasmon (SP) modes. As a result of the mode interaction, the avoided crossing patterns exhibit energy and momentum gaps, which depend on the configuration of the nano-structure and the wavelength. Variations of the widths of the SP resonances and an abrupt change of the mode interaction in the vicinity of the avoided crossing region are observed. These features are explained by the model of two coupled modes and a coupling change due to switching from the high frequency dark mode to the low frequency bright mode for increasing wavelength of the excitation light.

The targum (1885:May 15)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1885

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: The global Ordinary Portland Cement (OPC) industry is responsible for approximately 8% of annual anthropogenic carbon emissions as of 2018. Geopolymer cement pastes are a viable emission-free sustainable alternative to OPC which use industrial byproducts as binder precursors. In order to achieve comparable mechanical properties to OPC-based composites, geopolymer pastes must exhibit a high fluidity with a high cured ultimate compressive strength. In OPC pastes, this can be achieved with synthetic admixtures such as superplasticizers. However in the highly alkaline geopolymer environment, traditional superplasticizers will decompose. This paper discusses state of the art methods to achieve a superplasticizing effect in geopolymers through novel techniques that circumnavigate the need for traditional admixtures. In addition to a state of the art review, a hypothesis on geopolymer precursor etching as a means to create a superplasticizing, as well as shrinkage-reducing, effect in alkali activated materials is proposed.

Quando gioco imparo?: un percorso sull'apprendimento delle competenze geometriche attraverso un approccio ludico
Creators: name: Rossi, Giulia
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2020
Subjects: competenza – funzioni esecutive e attenzione – gioco – ciclo di apprendimento esperienziale

description: Il seguente lavoro di ricerca è volto a comprendere se un approccio ludico, in considerazione del coinvolgimento che comporta e dell’accresciuto livello di attenzione richiesto, aiuti positivamente l’apprendimento degli allievi, e soprattutto di quelli più in difficoltà. Per rispondere a questa domanda di ricerca, è stata proposta una sperimentazione che motivasse gli allievi ad apprendere nuove competenze geometriche utilizzando un approccio ludico: la costruzione di un gioco matematico. La metodologia utilizzata fa capo al Ciclo di apprendimento esperienziale che permette di abbinare il valore dell’emersione delle preconoscenze dell’allievo, attraverso l’esperienza e la sua riflessione sistematica. La ricerca svolta è di tipo qualitativo, i dati raccolti consistono nel confronto tra un test di profitto iniziale e finale riguardante il livello di ogni allievo nelle varie dimensioni geometriche, un’osservazione dei comportamenti tramite diario di bordo, un feedback intermedio da parte del docente e un’autovalutazione finale. L’analisi dei dati a disposizione svolta nel dettaglio permette di ipotizzare l’importanza del gioco nel apprendimento del bambino e nel suo livello di attenzione. D’altro canto viene sottolineata anche l’importanza della riflessione. Relatore: Matteo Piricò.

description: We derive an expression for the collective Casimir-Polder interaction of a trapped gas of condensed bosons with a plane surface through the coupling of the condensate atoms with the electromagnetic field. A systematic perturbation theory is developed based on a diagrammatic expansion of the electromagnetic self-energy. In the leading order, the result for the interaction-energy is proportional to the number of atoms in the condensate mode. At this order, atom-atom interactions and recoil effects lead to corrections compared to the single-atom theory, through shifts of the atomic transition energies. We also discuss the impact of the spatial delocalization of the condensate mode.

description: For the 1D-frustrated ferromagnetic J_1-J_2 model with interchain coupling added, we analyze the dynamical and static structure factor S(k,omega), the pitch angle phi of the magnetic structure, the magnetization curve of edge-shared chain cuprates, and focus on LiCuVO4 for which neither a perturbed spinon nor a spin wave approach can be applied. phi is found to be most sensitive to the interplay of frustration and quantum fluctuations. For LiVCuO4 the obtained exchange parameters J are in accord with the results for a realistic 5-band extended Hubbard model and LSDA + U predictions yielding alpha=J_2/|J_1| about 0.75 in contrast to 5.5 > alpha > 1.42 suggested in the literature. The alpha-regime of the empirical phi-values in NaCu2O2 and linarite are considered, too.

description: L’obiettivo del progetto è la realizzazione di un sistema in grado di controllare dispositivi basati sulla tecnologia a bus di campo LonWorks (LON), quali interruttori e attuatori per l’illuminazione domestica, attraverso semplici comandi vocali forniti allo smart speaker Google Nest Mini. Il sistema è composto da un’interfaccia di rete LON USB connessa ad un Raspberry Pi 4 contenente i driver necessari, il framework domotico Home Assistant e il software sviluppato LON-MQTT Bridge. Quest’ultimo rende possibile la comunicazione tra il framework domotico, lo smart speaker e i dispositivi LON, fornendo la possibilità di comandare e visualizzare lo stato attuale degli attuatori e di conseguenza delle luci. Per controllare l’illuminazione è sufficiente richiedere allo smart speaker l’accensione o lo spegnimento delle luci desiderate. Alternativamente è possibile utilizzare l’interfaccia grafica su un cellulare, tablet o un PC. Un possibile sviluppo futuro è l’espansione dei dispositivi LON supportati in modo da potere realizzare installazioni più avanzate e di conseguenza fornire un supporto maggiore alle persone bisognose. xi

description: O futsal e o basquetebol são duas modalidades coletivas praticadas em naves desportivas e com o mesmo número de jogadores de campo. Se no futsal existe um predomínio do uso dos membros inferiores em todos os momentos de jogo, com exceção do guarda-redes que utiliza também os membros superiores, na modalidade basquetebol recorre-se tanto aos membros superiores para fazer os lançamentos, como aos membros inferiores para a deslocação dos jogadores. Deste modo, com o presente estudo científico pretendeu-se comparar as características da aptidão física de cada modalidade em testes específicos e gerais de força, coordenação, velocidade e flexibilidade com o objetivo de analisar os efeitos da especificidade do treino. Recorreu-se a atletas juvenis masculinos de futsal e de basquetebol (n=8, respetivamente) e obtiveram-se os seguintes valores antropométricos: futsal, altura 1.75±0.09 m, peso 67.81±14.27 kg e índice de massa corporal (IMC) 22.05±3.54 kg/m2; basquetebol, altura 1.80±0.06 m, peso 68.53±6.14 kg e IMC 21.16±2.58 kg/m2. Após a aplicação da bateria de testes para análise da aptidão física, observamos diferenças estatisticamente significativas entre as duas modalidades na avaliação da força dos membros superiores (n.º flexões: P=0.018) apresentando valores superiores para a equipa de basquetebol (basquetebol: 28.38±2.13; futsal: 21.13±6.71). No teste de força dos membros inferiores não se verificou uma diferença significativa (Squat Jump: P=0.120; basquetebol: 1.65±0.23 m e futsal: 1.50±0.12 m). Na avaliação da coordenação (sprint 10 m com contorno de obstáculos) os atletas de futsal apresentaram valores superiores comparativamente aos de basquetebol (P=0.000, 7.40±1.49 seg. e 11.84±1.04 seg., respetivamente). Relativamente ao sprint de 20 m livres observou-se o contrário (P=0.013, 3.38±0.21 seg. e 3.13±0.10 seg., respe-tivamente). No entanto, relativamente à análise do sprint e eficácia, ambas as modalidades obtiveram valores idênticos (P=1.000; 0.25±0.46; 0.25±0.46). Por último, nos testes de flexibilidade, verificou-se que os atletas de futsal possuem flexibilidade superior nos 3 testes realizados, comparativamente aos basquetebolistas. Podemos concluir, fundamentalmente, que os jogadores de basquetebol possuem mais força ao nível dos membros inferiores e superiores e mais velocidade e coordenação, mas menor flexibilidade comparativamente aos jogadores de futsal.

Abiotic and biotic processes shape species distributions and ecological communities across spatial scales
Creators: name: Amundrud, Sarah Louise
Publisher: name: University of British Columbia
Year: 2020

description: Species distributions and the composition of ecological communities result from the interplay of three constraints: physical barriers to dispersal, species-specific environmental requirements, and species interactions. However, how spatial scale and environmental context affect the relative importance of these constraints is still poorly understood. I combined manipulative experiments, observational surveys along environmental gradients, and species distribution models to explore the relative importance of abiotic and biotic constraints on aquatic invertebrate communities inside bromeliads across a range of spatial scales. At the geographic scale (Central and South America), the distribution of a bromeliad-specialist damselfly was strongly limited by dispersal barriers and climate, but not by biotic interactions from other bromeliad-dwelling odonates. At the regional scale (along two elevational gradients in Costa Rica), the relative importance of abiotic and biotic constraints on species distributions and community assemblages depended on environmental context: while thermal tolerances (i.e., abiotic effects) explained invertebrate distributions under moist conditions, biotic interactions from crane fly larvae, which became predatory under drought, explained their distributions under dry conditions. At the local scale (the bromeliad), biotic interactions from crane fly larvae were disproportionally important in mediating the effects of drought and warming on community structure and ecosystem functions. This hierarchical set of studies demonstrates the scale-dependence of the interplay of abiotic and biotic processes in affecting species distributions and community assemblages. While species interactions were the main drivers of community change at the local scale of the habitat, biotic effects were not important at the large geographic scale. Notably, the relative importance of abiotic and biotic processes at the landscape scale depended on environmental context, an important insight given that environmental conditions are already shifting as a result of climate change.
