description: Corporate philanthropy has noticeably kept its momentum as a growing trend across the globe in various industries. While existing literature has mainly focused on the nature and motivation of corporate philanthropy from various perspectives, this dissertation shifts our attention to the variation of corporate philanthropy among organizations in the same industry. Specifically, the dissertation seeks to answer the following research question in the professional sport context: why do some teams give more than others despite being in the same industry? The dissertation aims to provide a comprehensive understanding of how institutional and organizational factors influence the philanthropic activities of professional sport teams through their associated charitable foundations. To this end, three distinct studies were conducted using longitudinal philanthropic giving data from team foundations in four professional sport leagues in the United States. The studies presented in the dissertation provide a multilateral understanding of the factors influencing professional sport teams’ corporate philanthropy. Study 1 examines how the presence of multiple peers from different institutional fields (i.e., professional sport league and geographic community) affects sport teams in terms of influencing their philanthropic contributions (Chapter II). The results suggest that sport teams are more likely to be affected by the philanthropic giving levels of their league peers than their local peers, and the effect of league peers is stronger when the team’s foundation size is smaller. Study 2 questions how community institutional forces (i.e., regulative, socio-normative, and cultural-cognitive) affect professional sport teams in terms of their charitable contributions (Chapter III). The findings show that higher state income tax rates and a greater presence of nonprofits in the community increase the level of team philanthropic giving. Study 3 explores the influence of team foundation governance on a professional sport team’s philanthropic giving (Chapter IV). The results suggest that larger foundation board size and presence of a paid foundation executive director increase philanthropic giving of professional sport teams. Collectively, the findings of this dissertation highlight that CP is a multifaceted and contextual organizational phenomenon whose drivers and outcomes vary by institutional and organizational environments in which professional sport teams operates.

description: In this paper we study the chemical history of low-mass star-forming (SF) galaxies in the local Universe clusters Coma, A1367, A779, and A634. The aim of this work is to search for the imprint of the environment on the chemical evolution of these galaxies. Galaxy chemical evolution is linked to the star formation history (SFH), as well as to the gas interchange with the environment, and low-mass galaxies are well known to be vulnerable systems to environmental processes affecting both these parameters. For our study we have used spectra from the SDSS-III DR8. We have examined the mass-metallicity relation of cluster galaxies finding well defined sequences. The slope of these sequences, for galaxies in low-mass clusters and galaxies at large cluster-centric distances, follows the predictions of recent hydrodynamic models. A flattening of this slope has been observed for galaxies located in the core of the two more massive clusters of the sample, principally in Coma, suggesting that the imprint of the cluster environment on the chemical evolution of SF galaxies should be sensitive to both the galaxy mass and the host cluster mass. The HI gas content of Coma and A1367 galaxies indicate that low-mass SF galaxies, located at the core of these clusters, have been severely affected by ram-pressure stripping. The observed mass-dependent enhancement of the metal content of low-mass galaxies in dense environments seems plausible, according to hydrodynamic simulations. This enhanced metal enrichment could be produced by the combination of effects such as wind reaccretion, due to pressure cofinement by the intra-cluster medium (ICM), and the truncation of gas infall, as a result of the ram-pressure stripping. Thus, the properties of the ICM should play an important role in the chemical evolution of low-mass galaxies in clusters.

description: Superfluorescence (SF) is the emission from a dense coherent system in population inversion, formed from an initially incoherent ensemble. This is characterised by an induction time (t_D) for the spontaneous development of the macroscopic quantum coherence. Here we report detailed observation of SF on ultrafast timescale from a quantum ensemble of coherent excitons in highly excited intrinsic bulk ZnTe single crystal at 5 K, showing a characteristic t_D from 40 ps to 10 ps, quantum noise and fluctuations, and quantum beating and ringing. From this clear observation of SF from a spontaneous coherence of excitons we infer that this is indicative of the formation of BEC of excitons on an ultrafast timescale.

description: Glassy polymers show strain hardening: at constant extensional load, their flow first accelerates, then arrests. Recent experiments have found this to be accompanied by a striking and unexplained dip in the segmental relaxation time. Here we explain such behavior by combining a minimal model of flow-induced liquefaction of a glass, with a description of the stress carried by strained polymers, creating a non-factorable interplay between aging and strain-induced rejuvenation. Under constant load, liquefaction of segmental motion permits strong flow that creates polymer-borne stress. This slows the deformation enough for the segmental modes to re-vitrify, causing strain hardening.

Publicidade, Moda e Representações de Género em plena Globalização

Year: 2013

description: Este artigo reflete sobre a influência que a Publicidade e a Moda, e em particular a Publicidade de Moda têm enquanto modelos de referência, tanto para a construção da identidade pessoal (onde a aparência surge como reflexo), como para a interiorização dos modelos de conduta associados às representações de género veiculadas que ajudam a interpretar a realidade social. Publicidade e Moda são produtos culturais e a Publicidade de Moda utiliza códigos, transmite mensagens numa linguagem “quase“ silenciosa sendo expressão da cultura atual. Outrora símbolo de estatuto social, a Moda é agora símbolo de criação identitária própria através dos olhos dos outros, ou seja num contexto de relações sociais. A busca é a diferenciação como indivíduo e os sinais das marcas de moda são usados pelos indivíduos na afirmação da sua unicidade, da sua originalidade. Particularmente na imagética da publicidade de moda, há já algumas décadas que a publicidade é palco do simbolismo sexual, tanto na sensualidade ligada a determinados ideais de aparência ou beleza, como no papéis e relações entre géneros que são aprendidos e representados socialmente. De facto, os efeitos da comparação entre as imagens do corpo e a realidade do próprio corpo, podem resultar em julgamentos negativos acerca da imagem corporal e uma forte pressão para as mulheres, mas também para os homens, na tentativa algo inglória para alcançar um ideal, na maior parte das vezes irreal, porque é o resultado de simulações várias transmitidas pelas imagens publicitárias. Por outro lado, o género é um traço identitário profundamente implicante para o ser humano pois culturalmente liga-se a noção de género aos papéis sexuais e sociais definidos para os indivíduos. Ao nível das representações de género, este é um tempo “em aberto”, tudo é possível, porque os papéis femininos e masculinos veiculados pela publicidade se vão gradualmente modificando, mas em coexistência com os papéis mais estereotipados de outrora e os mais revolucionários do amanhã, transformando o agora num momento algo ambíguo.

We establish the phase diagram for filling $n=1$ at zero and finite temperature, by applying Bosonic Dynamical Mean-Field Theory, and confirm the stability of pair-superfluidity for asymmetric hopping of the two species. While the pair superfluid is found to be robust in the presence of a harmonic trap, we observe that it is destroyed already by a small population imbalance of the two species.

description: Vivemos num mundo cada vez mais heterogéneo, onde os riscos de conflitos culturais são eminentes. O mundo está em mudança e pessoas de diversas culturas, formas de estar e mentalidades partilham o mesmo espaço (cf. Ravazzani, 2006). Apesar de existir homogeneidade ao nível de alguns valores de referência transacionais, existe também uma maior noção da existência da diversidade de valores. É essencial que os Profissionais de Comunicação compreendam os valores dos seus stakeholders, de forma a alinharem, estrategicamente, a comunicação das organizações. De um ponto de vista social, os valores assumem um papel fundamental nas relações humanas e, do nosso ponto de vista, a sua compreensão, essencial para uma comunicação eficaz, apenas é possível quando conhecemos e percebemos a base desses sistemas de valores, os quais determinam as atitudes e ações dos seres humanos em relação a determinado assunto ou objeto. Os resultados preliminares da nossa pesquisa sobre os valores, revelaram que estes podem assumir uma tipologia de Absolutos ou Relativos, podendo apresentar diferentes posições na arena de significados onde a compreensão se desenvolve. Estas diferentes posições podem originar quatro tipos diferentes de conflito – paz, turbulência, ofensivo e defensivo –, sendo que a estratégia de comunicação de uma organização deve ter o tipo de conflito em conta. Neste sentido, este artigo apresenta uma tipologia de atuação estratégica que, compreendendo as estruturas valorativas que se desenvolvem em sociedade, permite aos Profissionais de Comunicação compreender cada tipo de conflito e atuar sobre ele. O nosso trabalho apresenta um quadro conceptual que fornece indicações sobre como atuar em cada tipo de conflito, abrindo caminho para aquilo que apelidamos de Teoria Situacional do Discurso baseada em Valores. Construído com base numa conceção sociológica sobre a noção de Valores, ao modelo é aplicado a noção de Valores Perelmaniana, sendo que na interseção das duas podemos construir as linhas estratégicas a adotar de forma a lidar com cada tipo de conflito. Este artigo tem implicações para o estudo Sociológico da Comunicação, uma vez que fornece orientações sobre como as organizações podem comunicar estrategicamente na Arena de Significados, onde os Valores assumem diferentes tipos de conflitos, com o intuito de estarem tão perto quanto possível de uma conceção universal dos mesmos. Tem ainda implicações no mundo académico, uma vez que explora a importância dos Valores na compreensão social do mundo por parte das organizações e na sua orientação estratégica.

description: Understanding the relationships between DNA sequence and organismal phenotypes has been a central goal across a wide variety of biological subdisciplines throughout the history of genetics research. Studies of the developmental genetic mechanisms underlying phenotypes aim to increase our understanding of how genotypes encode phenotypes, while studies of the genetic basis of evolved differences inform our understanding of how changes in DNA sequence alter these developmental processes. While the fields of evolution and development have been mutually informative, our ability to interpret genetic sequences remains severely limited. In this dissertation, I investigate the genetic basis of phenotypic evolution and development using pigmentation in the genus Drosophila as a model system. In order to overcome technical limitations in identifying the genetic basis of evolved differences in Drosophila pigmentation, I adapted CRISPR/Cas9 genome editing techniques for precise DNA sequence replacement, developing methods designed for use in a wide variety of Drosophila species. Using CRISPR/Cas9, I demonstrate the role of the ebony gene in an evolved pigmentation difference between Drosophila novamexicana and Drosophila novamexicana, as well as in the development of cuticular hydrocarbons in these species. Finally, I describe the previously under-studied role of microRNAs in the development of Drosophila melanogaster pigmentation in a large-scale genetic screen, introducing a new class of regulators into the existing body of research into the genetic architecture underlying this development of this model trait.

description: A comunicação constitui, hoje, um agente fundamental para as sociedades evoluídas, para além de se perceber tratar-se de um fenómeno multidisciplinar, complexo, muito por força da conjugação de um binómio, distinto embora interdependente, que lhe serve de etiologia: capitalismo e tecnologia. Parece-me claro que os media se constituem agora como um poderoso sistema maquínico, não apenas complexo mas também inebriante, entorpecente e mobilizador no que respeita à produção de afectos. Daí ser meu propósito interrogar qual o papel do Homem na contemporaneidade, tanto na sua relação com os media como com a tecnologia, percebendo desde logo que vivemos numa sociedade consumista, acelerada, estetizada e sob um permanente manto diáfano de sombras que tende eventualmente a esgotar-nos em emoção. Assim se justifica a perspetiva segundo a qual a nossa preocupação não recai sobre o presente mas antes sobre a vivência em si, isto é, sem tempo definido, sem território, sem ideologia. Agora, numa era híbrida e com uma cultura própria assente em dicotomias várias que convivem sob uma aparência harmoniosa, experienciamos uma época de certo modo peculiar onde, a meu ver, parecemos habitar numa ambiência difusa, conjugando a inovação com a hibridez num complexo fluxo de interatividades que nos esbate a fronteira entre real e virtual, entre natureza e simulacro, entre humano e inumano, no que me atrevo aqui qualificar como «paramodernidade».

description: Quer o nascimento dos indivíduos tenha ocorrido na altura do surgimento da televisão, do computador ou do telemóvel, todos eles representam um papel diferente nas suas atividades quotidianas, percecionados como imprescindíveis na medida em que são considerados como necessários para manter contacto com os pares ou familiares, como forma de entretenimento, para trabalhar ou estudar, etc. A utilização dos novos media ocorre de forma transversal aos contextos e tempos sociais, mas também às relações, quer sejam as estabelecidas entre indivíduos pertencentes à mesma geração ou a gerações diferentes. É sobre estas em particular que se debruça o interesse desta comunicação. Pretende-se refletir sobre a mediação e até a potenciação que os media elaboram para a e na ocorrência das relações intergeracionais, mais concretamente, as relações familiares entre pais, filhos e avós, residentes em meio rural. Com esse objetivo, analisam-se os inquéritos por questionário aplicados no território rural português (Continente e Ilhas) no ano de 2012, no âmbito da tese de doutoramento “Gerações de ecrã em meio rural”, desenvolvida na Universidade de Aveiro e na Faculdade de Letras da Universidade do Porto.

description: Feedback or closed-loop control allows dynamical systems to increase their performance up to a limit imposed by the second law of thermodynamics. It is expected that within this limit, the system performance increases as the controller uses more information about the system. However, despite the relevant progresses made recently, a general and complete formal development to justify this statement using information theory is still lacking. We present here the state-of-the-art and the main open problems that include aspects of the redundancy of correlated operations of feedback control and the continuous operation of feedback control. Complete answers to these questions are required to firmly establish the thermodynamics of feedback controlled systems. Other relevant open questions concern the implications of the theoretical results for the limitations in the performance of feedback controlled flashing ratchets, and for the operation and performance of nanotechnology devices and biological systems.

Supramolecular schiff base coordination chemistry : blueprints for self-assembling metallocavitands and nanotubes
Creators: name: Frischmann, Peter David
Publisher: name: University of British Columbia
Year: 2013

description: Heptametallic zinc(II) and cadmium(II) clusters have been isolated after reacting the metal-acetate salts with large diameter [3+3] Schiff base macrocycles. Two tetrazinc complexes have been characterized and identified as intermediates in the formation of the heptazinc complexes. The heptametallic complexes are, in fact, templated by the Schiff base macrocycles, a process that has been investigated with ¹H NMR spectroscopy and single-crystal X-ray diffraction. In the solid-state the heptametallic complexes have a bowl-shaped geometry, reminiscent of organic cavitands, leading to them being called metallocavitands. Solid-state investigation of the heptazinc and heptacadmium metallocavitands showed they organize into capsules with a cavity volume of 150 and 215 Å³, respectively. Solution dimerization was also observed in aromatic solvents and N,N-dimethylformamide (DMF). The thermodynamics of dimerization have been quantified by van’t Hoff analyses of association constants measured with variabletemperature, variable-concentration ¹H NMR spectroscopy. Both metallocavitands exhibit entropy-driven dimerization in all solvents in which dimerization occurs. Unusual for dimerization of cavitands, this entropy-driven process can be attributed to the expulsion of solvent from the monomeric cavity upon dimerization. Inside the cavity of heptacadmium metallocavitands is a μ₃-OH ligand where the proton is located at the base of the cavity and is capable of hydrogen bonding with guest molecules. The μ₃-OH proton resonance is observable in low temperature 1H NMR spectra and exhibits two-bond J-coupling with three cadmium ions. Within capsules of the heptacadmium metallocavitands there are eight Lewis-acidic sites accessible to guest molecules, six unsaturated cadmium(II) centers and two μ₃-OH ligands. Solid-state analysis shows that two DMF molecules are encapsulated in the heptacadmium capsule where they each simultaneously exhibit a host-guest hydrogen-bond and a dative metalligand interaction. New methodology has been developed that facilitates synthesis of polydentate [2+2] Schiff base macrocycles with unsymmetrical salphen pockets. Also a [3+3] macrocycle with triptycenyl substituents has been synthesized to prohibit alkali-metal induced solution aggregation. The one-pot twelve component head-to-tail self-assembly of Pt₄ rings directed by chelating imine-pyridyl donors has been demonstrated. These supramolecules exhibit extensive columnar organization in both solution and the solid-state, a phenomenon that imparts liquid crystalline properties on the macrocycles.

description: Quality of Service (QoS) techniques are applied in IP networks to utilize available network resources in the most efficient manner to minimize delays and delay variations (jitters) in network traffic having multiple type of services. Multimedia services may include voice, video and database. Researchers have done considerable work on queuing disciplines to analyze and improve QoS performance in wired and wireless IP networks. This paper highlights QoS analysis in a wired IP network with more realistic enterprise modeling and presents simulation results of a few statistics not presented and discussed before. Four different applications are used i.e. FTP, Database, Voice over IP (VoIP) and Video Conferencing (VC). Two major queuing disciplines are evaluated i.e. 'Priority Queuing' and 'Weighted Fair Queuing' for packet identification under Differentiated Services Code Point (DSCP). The simulation results show that WFQ has an edge over PQ in terms of queuing delays and jitters experienced by low priority services. For high priority traffic, dependency of 'Traffic Drop', 'Buffer Usage' and 'Packet Delay Variation' on selected buffer sizes is simulated and discussed to evaluate QoS deeper. In the end, it is also analyzed how network's database service with applied Quality of Service may be affected in terms of throughput (average rate of data received) for internal network users when the server is also accessed by external user(s) through Virtual Private Network (VPN).

description: O conceito de boato tem sido abordado, amiúde, sob dois conjuntos de perspectivas predominantes: o primeiro, centrado nos seus conteúdos e origens, discutindo-se ora a verdade ou falsidade da matéria tratada, ora a razão mítica ou arquetípica mais profunda, ora a natureza das angústias e ansiedades que alimentam a sua reprodução; o segundo discute o processo, analisando as etapas e percursos de retransmissão, o trajecto de saturação do meio, a latitude das suas transformações e a racionalidade mecânica da redução e estabilização das suas versões. Menos frequente, uma terceira leitura procura dar, ainda, conta dos usos sociais e culturais do boato como estratégias de avaliação, nas comunidades, do impacte da informação emergente induzida. O presente trabalho visa interrogar algumas destas abordagens, a persistência do conceito e, como proposta de leitura, revisitar o seu uso, ambivalente, como forma de classificação, reflectido-se nesta a diversidade de poderes e interesses dos contextos em que circula.

Tecnologias e pessoas mais velhas: as Novas Tecnologias de Informação e Comunicação nas relações sociais de seniores em Portugal
Creators: name: Azevedo, Celiana

Year: 2013

description: Duas tendências têm afetado a sociedade portuguesa: a evolução e difusão das tecnologias de informação e comunicação - TIC - e o envelhecimento da população, ou seja, a “sociedade de informação” está a envelhecer (Bernard & Phillips, 2000). Assim, esta pesquisa analisa a importância do uso das novas tecnologias de informação e comunicação, nomeadamente o computador, a internet e o telemóvel nas relações sociais em um grupo de pessoas mais velhas em Portugal. Como metodologia, utilizamos grupos de foco e trabalhamos com seniores com idades entre 61 e 93 anos, que viviam na região de Lisboa. A partir deste trabalho, podemos afirmar que a apropriação e uso do telemóvel, do computador e da internet podem influenciar positivamente as relações sociais de pessoas mais velhas.

Chemical physics and the condensed phase : NMR studies in a liquid-crystal testing ground
Creators: name: Weber, Adrian C. J.
Publisher: name: University of British Columbia
Year: 2010

description: Liquid crystals are an excellent media for the study of the condensed phase by NMR spectroscopy since the highly accurate proton dipolar couplings do not average to zero as they do in the isotropic condensed phase. Of course we can also take the opposite view and seek to understand the behavior of individual molecules and the effect of the condensed phase on them and so the impetus for studies of solutes in liquid crystals is two fold. By coupling theory to experiment via dipolar couplings one can gain insight into aspects of chemical physics and the condensed phase provided the spectra can be solved. As the number of spins of a molecule and its lack of symmetry increase so do the complexity of NMR spectra of solutes in orientationally ordered phases. Covariance Matrix Adaptation Evolutionary Strategies (CMA-ES) have proven to be remarkably useful towards the end of obtaining dipolar couplings from congested spectra. In essence this algorithm uses the principles of natural selection coupled with an aspect of cross-generational memory to find the set of spectral parameters at the global minima of an error surface which reproduce the experimental spectrum. It is not an overstatement to say this tool has significantly altered the allocation of efforts in the area of research presented here. In the research herein two approaches are employed which are complimentary. In the first chapters we use a diversity of solutes to test postulated interaction Hamiltonians intended to describe the intermolecular environment of nematic and smectic A phases. The putative Hamiltonians are fitted to solute order parameters obtained from dipolar couplings. Once an explicit form is obtained, reasonable speculation is made concerning what the Hamiltonian can tell us about the intermolecular environment of the condensed phases studied. In the latter chapters the complimentary view is taken. Specifically we attempt to understand how internal rotations of molecules are affected by the condensed phase environment. To this end is considered the simplest example in n-butane. Again by obtaining dipolar couplings we can use a variety of theoretical tools in an attempt to exploit the full accuracy of these anisotropic spectral parameters and gain insight into the effect of a condensed phase on configurational statistics. These phenomena are also studied as a function of temperature.

Triton photodisintegration in three-dimensional approach

description: Two- and three- particles photodisintegration of the triton is investigated in a three-dimensional (3D) Faddeev approach. For this purpose the Jacobi momentum vectors for three particles system and spin-isospin quantum numbers of the individual nucleons are considered. Based on this picture the three-nucleon Faddeev integral equations with the two-nucleon interaction are formulated without employing the partial wave decomposition. The single nucleon current as well as $π-$ and $ρ-$ like exchange currents are used in an appropriate form to be employed in 3D approach. The exchange currents are derived from AV18 NN force. The two-body t-matrix, Deuteron and Triton wave functions are calculated in the 3D approach by using AV18 potential. Benchmarks are presented to compare the total cross section for the two- and three- particles photodisintegration in the range of $E_γ<30 MeV$. The 3D Faddeev approach shows promising results.

description: We present results of high-resolution imaging toward HL Tau by the Combined Array for Research in Millimeter-wave Astronomy (CARMA). We have obtained 1.3 and 2.7 mm dust continua with an angular resolution down to 0.13 arc second. Through model fitting to the two wavelength data simultaneously in Bayesian inference using a flared viscous accretion disk model, we estimate the physical properties of HL Tau, such as density distribution, dust opacity spectral index, disk mass, disk size, inclination angle, position angle, and disk thickness. HL Tau has a circumstellar disk mass of 0.13 solar mass, a characteristic radius of 79 AU, an inclination of 40 degree, and a position angle of 136 degree. Although a thin disk model is preferred by our two wavelength data, a thick disk model is needed to explain the high mid- and far-infrared emission of the HL Tau spectral energy distribution. This could imply large dust grains settled down on the mid plane with fine dust grains mixed with gas. The HL Tau disk is likely gravitationally unstable and can be fragmented between 50 and 100 AU of radius. However, we did not detect dust thermal continuum supporting the protoplanet candidate claimed by a previous study using observations of the Very Large Array at 1.3 cm.
