Affective Sustainability. The Creation and Transmission of Affect through an Educative Process: An Instrument for the Construction of more Sustainable Citizens
Although for many years the debate on sustainability has focused on the generation of
critical thinking based on the dynamic balance between the economic, social and environmental
spheres, in the following text we propose to elaborate on the use of a eminently human condition,
such as the capacity to love and create an emotional attachment, whether with our environment or
our fellow men, as an initiator and main force for change to the building a more sustainable model
of development. To do so we shall begin from the concept coined by Adriana Bisquert in the 90s,
that is A ective sustainability, by analyzing it, delving into its possible definitions by means of the
development of the project for Environmental Education and Development called âEducating for a
more sustainable citizenshipâ undertaken by the Spanish NGO (non-governmental organization) or
ITACA Ambiente Elegido, and developed in the locality of Paterna de Rivera, CĂĄdiz (Spain). This is a
practical and real example, which is used to establish a work educational methodology that enables
us to consider this concept as the real basis for an exportable and replicable work in a painstaking
search for the creation of a more sustainable city
Virtual Meeting Rooms: From Observation to Simulation
Virtual meeting rooms are used for simulation of real meeting behavior and can show how people behave, how they gesture, move their heads, bodies, their gaze behavior during conversations. They are used for visualising models of meeting behavior, and they can be used for the evaluation of these models. They are also used to show the effects of controlling certain parameters on the behavior and in experiments to see what the effect is on communication when various channels of information - speech, gaze, gesture, posture - are switched off or manipulated in other ways. The paper presents the various stages in the development of a virtual meeting room as well and illustrates its uses by presenting some results of experiments to see whether human judges can induce conversational roles in a virtual meeting situation when they only see the head movements of participants in the meeting
The pi -> pi pi process in nuclei and the restoration of chiral symmetry
The results of an extensive campaign of measurements of the pi -> pi pi
process in the nucleon and nuclei at intermediate energies are presented. The
measurements were motivated by the study of strong pi pi correlations in
nuclei. The analysis relies on the composite ratio C_{pi pi}^A, which accounts
for the clear effect of the nuclear medium on the (pi pi) system. The
comparison of the C_{pi pi}^A distributions for the (pi pi)_{I=J=0} and (pi
pi)_{I=0,J=2} systems to the model predictions indicates that the C_{pi pi}^A
behavior in proximity of the 2m_pi threshold is explainable through the partial
restoration of chiral symmetry in nuclei.Comment: accepted for publication in Nucl. Phys.
Double Relative Deprivation: Combining the Personal and Political
Double relative deprivation, which has been virtually ignored in research on relative deprivation, was expected to predict women\u27s collective action over and above egoistic and collective deprivation. The role of socio-political resources in perceiving deprivation and participation in action was also investigated. Female students (N=164) completed a questionnaire designed to assess their perceptions of egoistic, collective, double relative deprivation (defined as the interaction between egoistic and collective deprivation), resource availability and participation in collective action. Hierarchical regression analyses indicated that double relative deprivation predicted collective action over and above egoistic and collective relative deprivation, and that resource availability also uniquely predicted action. Implications for expanding conceptual and operational definitions of these constructs are discussed
Quantum trajectory analysis of a thresholdlike transition in the microlaser
In a recent microlaser experiment [K. An et al., Phys. Rev. Lett. 73, 3375 (1994)], a thresholdlike transition of intracavity mean photon number as a function of intracavity mean atom number has been observed. In this paper the behavior is explored with quantum trajectory simulations. It is shown that the transition is caused by enhanced atom-cavity Rabi interaction due to the increase of the intracavity photon number as the intracavity atom number is increased. The transition is further accentuated by the position-dependent variation of the coupling constant in the Fabry-PĂ©rot cavity. In addition, it is demonstrated that multiatom collective effects are negligible in the microlaser under consideration, in which atoms are injected into the cavity at random times and the product of the coupling constant and atom-cavity interaction time is much less than Ï. In this case the analytic theory of the one-atom micromaser [P. Filipowicz et al., Phys. Rev. A 34, 3077 (1986)] can be extrapolated into the multiatom region, assuming uniform atom-cavity coupling throughout the cavity and monovelocity atomic injection. Finally, simulations are performed which account for spatial variation of coupling constant, velocity distribution of injected atoms, and spontaneous atomic decay in the actual experiment. The results are in good agreement with experiment
Resilience from a lived-experience perspective in the regional context of Dumfries and Galloway, Scotland
Within the UK, academics and practitionersâ understanding of resilience have been increasingly nuanced, particularly after the introduction of the Civil Contingencies Act (CCA) 2004. However, there remain debates and variations in how resilience is conceptualised that creates confusion in how resilience building is operationalised in practice by stakeholders. To address this concern, this study explores the meaning of resilience from the perspectives of people with a lived experience of flooding, through the lens of adaptive capacity, which is a key dimension of resilience as identified in Scottish policy frameworks. Insight from a literature review combined with empirical data collected from forty-three participants, suggests that resilience to natural hazards is a function of two inter-related aspects: âinformationâ and âresponseâ mechanisms. Further analysis suggests that resilience enhancement begins following receipt of risk information from either experience or other sources that shapes the understanding of a hazard and what protective steps to take. This understanding prompts behavioural responses influenced by ârisk attitudeâ, âskillsâ and âaccess to resourcesâ to enhance the adaptive capacity of the receiver. The paper engages in the complex debate about how resilience is conceptualized from the social sciences perspective. It presents a simplified account of what resilience means and sets out policy and practical implications of this
The Low Mass X-ray Binary - Globular Cluster Link and its Implications
Studies of nearby elliptical and S0 galaxies reveal that roughly half of the
low mass X-ray binaries (LMXBs), which are luminous tracers of accreting
neutron star or black hole systems, are in clusters. There is a surprising
tendency of LMXBs to be preferentially associated with metal-rich globular
clusters (GCs), with metal-rich GCs hosting three times as many LMXBs as
metal-poor ones. There is no convincing evidence of a correlation with GC age
so far. In some galaxies the LMXB formation rate varies with GC color even
within the metal-rich peak of the typical bimodal cluster metallicity
distribution. This provides some of the strongest evidence to date that there
are metallicity variations within the metal-rich GC peak, as is expected in
hierarchical galaxy formation scenarios. We also note that apparent
correlations between the interaction rates in GCs and LMXB frequency may not be
reliable because of the uncertainties in some GC parameters. We argue in fact
that there are considerable uncertainties in the integrated properties of even
the Milky Way clusters that are often overlooked.Comment: To be be published in the proceedings of, "A Population Explosion:
