Solidariedade, dádiva e mercados privados numa comunidade eborense : sustentabilidade e processos constitutivos dos agentes de cuidado
Existem hoje em Portugal situações de ampla e expressa carência multidimensional de base
fundamentalmente socioconómica, para as quais as instituições de bem estar público não
têm oferecido ajuda suficiente e dedicada. As narrativas de necessidades são correntes nos
quotidianos, verificando-se a emergência de processos de cuidado informal e de ajuda
variada ao Outro. Nesse sentido, produzem-se mecanismos e modelos de ação privados de
abrangência coletiva, engenhosamente articulados com as (macro) estruturas formais. As
práticas de cuidado informal, solidárias e de voluntariado, geram novos mercados sociais,
afectivos e morais, assentes em noções coletivamente partilhadas de bem, justiça e
moralidade. Neste trabalho procuro analisar como esses mercados intentam resolver
aquelas situações deficitárias, através da dádiva e troca recíproca de bens e capitais
múltiplos, considerando que essas ações evidenciam uma mudança social para paradigmas
ecológicos, políticos e económicos mais sustentados, que adquirem importância central nos
processos de reprodução social e de melhoria das condições de vida dos agentes sociais.Currently in Portugal there are situations of broad and visible multidimensional human
absence, grounded primarily in socioeconomic factors, to which public welfare institutions,
have not offered enough and specialised support. The speeches about human needs are
common nowadays, with processes of informal care and varied support of the Other
becoming even more emerging. Mechanisms and private action models of collective scope
thus show up, which are resourcefully linked with (macro) formal structures. Informal
practices of care, solidarity and volunteering, create new social, affective and moral markets,
grounded in collective and shared senses of common good, justice and morality. In this
dissertation I will analyse how these markets try to solve these deprived situations, through
share and reciprocal exchange of goods and varied capitals that substantiate a social
change that lead to new and more sustainable ecological, political and economic paradigms
and bear key importance in the social reproduction process and in living conditions

Words make people think, ... but pictures make people feel: The effect negative vs. positive images on charitable behavior
We ran an experiment where the subjects initially played a four-round dictator game, after which each subject was shown either a set of positive images or a set of negative images. Finally the subjects played another four-round dictator game.
The effect of the sign of images shown is clear on the players’ behaviors: positive images have moderate effects on charitable behavior while negative images dramatically increase charity.
We could therefore infer from our experimental results that showing negative images of the Haitian and Chilean catastrophes to the international public would have significant positive impacts on international donations to the victims and the rebuilding programs in both countries
"E o que é que é preciso para ser voluntário?": voluntariado como modelo de governança em contextos de crise: Portugal 2012-2018
As organizações de solidariedade social proliferaram em Portugal no período da austeridade,
mobilizadas por um impulso ético coletivo que visava suprir necessidades de emergência do
período da "crise". Esta tese analisa as representações/necessidades inscritas no voluntariado
alimentar e de proximidade, inserido num contexto politico paradigmático de ação social e
alicerçado na transferência de parte da responsabilidade pública para as organizações
privadas. O trabalho de campo foi realizado em quatro organizações de voluntariado em
Évora, Lisboa e Setúbal, que ofereciam recursos materiais doados na comunidade - bens
básicos - aos beneficiários e procuravam suprir necessidades imateriais (cuidado e
companhia). A atividade voluntária cruza domínios privados, casa e família,
institucionalizando uma parceria de apoio social partilhada com o Estado, que corporiza uma
gestão "combinada" de "crise". Esta interseção é fundamental para a reprodução da pessoa e
da família e evita o colapso das comunidades nas quais as organizações atuam. O paradigma
assenta na disseminação de uma retórica pública de empoderamento dos agentes privados,
pessoas e instituições, uma ética "moralizadora" que instiga os cidadãos para a ação social.
Porém, os beneficiários das organizações de solidariedade revelam sentidos de precarização e
de perdas simbólicas, o que rompe com as suas noções de bem estar social e com o princípio
keynesiano de confiança, pilar basilar do Estado Providente. O modelo de governança
paritária deverá se alvo de revisão dado que interfere nas economias reais, sobretudo em
contextos de crise onde fazer a vida depende, em grande medida, da providência social.In Portugal, voluntary social organisations expanded during austerity and were mobilised by
a collective ethic impulse which aimed to solve emergency needs at the time of "crisis". This
thesis examines representations/needs inscribed in food and proximity volunteering, which is
inserted in a paradigmatic political social action framework grounded in the transfer of part
of public liabilities. Fieldwork was made in four volunteering organisations localised in
Évora, Lisboa e Setúbal which offered material resources donated by the community - basic
goods - to the beneficiaries and tried to solve intangible needs (care and company). Voluntary
activity intersects private domains, household and family, institutionalising social assistance
partnerships with the State, which embodies a "shared" management of "crisis". This junction
is crucial to family and individual reproduction and prevents the collapse of the communities
where organisations operate. This paradigm is settled in a public rhetoric of empowerment of
private agents and institutions, a "moralising" ethic which stimulates citizens to social action.
However, solidarity organisations’ recipients reveal precarisation senses and symbolic loses,
which breaks their well-being notions and keynesian principle of trust, which is a
fundamental pilar of Welfare State. This joint governance model has to be reviewed since it
intervenes whit real economies of society, specially in crisis situations where getting by
depends on social provision to a large extent
Conducting Molecular Nanomagnet of DyIII with Partially Charged TCNQ Radicals
artículo científicoBifunctional electrically conducting single-molecule magnets are highly promising platforms for non-volatile memory devices and quantum computing applications. The development of these molecular materials, however, has largely been hindered by the lack of straightforward synthetic methods. Herein we demonstrate a facile and modular approach for the realization of bifunctional materials that does not require electrochemical or chemical oxidation to obtain partially charged organic radicals. Magnetic and electrical conductivity studies reveal that the Dy(III) compound exhibits slow relaxation of the magnetization between 5.0-8.0 K and semiconducting behavior over the range 180-350 K. DC magnetic fields suppress the quantum tunneling of the magnetization and affect the spin-canted antiferromagnetic interactions.U.S. Department of Energy
Facile synthesis of Cd-substituted zeolitic-imidazolate framework Cd-ZIF-8 and mixed-metal CdZn-ZIF-8
scientific paperZeolitic-imidazole framework ZIF-8 has attracted tremendous interests for the highresolution kinetic separation of propylene/propane mixture due to its effective aperture size in between the sizes of propylene and propane molecules. It is of great interest to fine-tune the effective aperture size of ZIF-8 either to improve its propylene/propane separation performances or to extend its use to the separation of other gas mixtures. It has been shown that substituting Zn with other metal nodes (e.g. Co) is a potential means to fine-tune the effective aperture size of ZIF-8. Here, we attempt to introduce another metal center, Cd, into ZIF-8 in a facile and scalable manner. Phase-pure Cd-ZIF-8 was successfully synthesized in methanol using a conventional solvothermal method, although it showed a narrow synthesis window. The presence of an organic base (triethylamine, TEA) was found critical not only for the facile synthesis of phase-pure Cd- ZIF-8 but also for the suppression of its phase transformation. A battery of characterizations including single-crystal X-ray structure solutions confirmed that the effective aperture size of Cd-ZIF-8 is the largest among its iso-structures (Zn-ZIF-8 and Co-ZIF-8). Finally, for the first time, mixed-metal CdZn-ZIF-8 crystals with various Cd/Zn ratios were solvothermally synthesized, demonstrating a further opportunity for varying the effective aperture sizes of ZIF-8 and its iso-structures.National Science Foundation Qatar National Research Fund Texas A&M Engineering Experimental Station

Relaxation Dynamics of Identical Trigonal Bipyramidal Cobalt Molecules with Different Local Symmetries and Packing Arrangements: Magnetostructural Correlations and ab inito Calculations
A family of isostructural, mononuclear CoII
complexes with distorted trigonal bipyramidal coordination
environments is reported. The degree of distortion as well as
the overall symmetry of the molecules varies among the
members of the series. Different experimental procedures
resulted in the isolation of solvomorphs (pseudopolymorphs
with different solvent content) for some of the family
members. Importantly, their disparate packing arrangements
lead to very different dynamic magnetic behavior. The results
of magnetostructural correlations and ab initio calculations
reveal that the deciding factor for SMM behavior is not the degree of distortion which, a priori, would be expected to be the case,
but rather the interactions between neighboring molecules in the solid state.Department of Energy, Basic Energy Sciences, Materials

Magnetic ordering in self-assembled materials consisting of cerium(III) ions and the radical forms of 2,5-TCNQX 2 (X=Cl, Br)
Ribbon-like coordination polymers composed of CeIII ions and TCNQX2 (TCNQ=tetracyanoquinodimethane; X=Cl, Br), but not TCNQ radicals, show unexpected magnetic ordering (see picture; Ce green). This behavior reveals remarkable subtlety for magnetic properties of lanthanide–organic materials
Strong Ferromagnetic Exchange Coupling Mediated by a Bridging Tetrazine Radical in a Dinuclear Nickel Complex.
The radical bridged compound [(Ni- (TPMA))2-μ-bmtz•−](BF4)3·3CH3CN (bmtz = 3,6-bis- (2′-pyrimidyl)-1,2,4,5-tetrazine, TPMA = tris(2- pyridylmethyl)amine) exhibits strong ferromagnetic exchange between the S = 1 NiII centers and the bridging S = 1/2 bmtz radical with J = 96 ± 5 cm−1 (−2JNi‑radSNiSrad). DFT calculations support the existence of strong ferromagnetic exchange.Department of Energy Office of Science Graduate Fellowship, Instituto de Ciencia y Tecnología del Distrito Federal (ICyTDF) National Science Foundation (CHE-1310574) and the Robert A.
