Anomalias da ExperiĂŞncia do Eu Fora do Espectro da Esquizofrenia
Baseado num trabalho apresentado oralmente no 7º Simpósio do Serviço de Psiquiatria do Hospital Professor Doutor Fernando Fonseca EPE, que teve lugar a 10 e 11 de Março de 2017.Anomalous Self-Experiences (ASE) are probably the most important contemporary conceptual and empirical research topic in the field
Psychopathology of Schizophrenia. The set of
these subjective phenomena constitute particular traits of schizophrenic subjects which
were shown to be present in the first episode
of psychosis, in prodromal and in Ultra-HighRisk states. Outstandingly, such enquiries have
raised the standard of the psychopathological
examination and endorsed reconsidering that
subjective phenomena might increase validity
of a psychiatric category without sacrificing
reliability. They include changes in thought,
self and bodily experience, reality contact
and existential orientation. The keynote explored new ways of ASE’s symbolization as is
the case of Truman Symptoms and abnormal
bodily experiences subsets in Ultra-High-Risk
subjects. Also, it further isolated ASE in new
settings such as anxiety disorders. The keynote
presented the results of three studies including
two studies in Ultra-High-Risk subjects and in
Panic Disorder subjects characterizing their
profile and considering possible differences
from schizophrenia. All of them aim to be a
necessary first step to sanction a new set of
enquiries contemplating other subjective phenomena that might occur in schizophrenia
and recognizing the possible role of addressing
subjectivity in determining psychopathology
of other disorders.info:eu-repo/semantics/publishedVersio
The pinewood nematode, Bursaphelenchus xylophilus, in Madeira Island
The environmental conditions in Madeira Island are favorable
for the presence and dissemination of the pinewood
nematode (PWN), Bursaphelenchus xylophilus. Five hundred
Pinus pinaster wood samples were collected in several
forest areas and PWN was detected in 22.8 % of the
samples. Bursaphelenchus xylophilus isolates from Madeira
Island displayed the species-specific diagnostic characters.
A morphological variation in the female tail terminus was
detected. In most females, the tail presented a broadly
rounded terminus and, occasionally, a digitate terminus with
a terminal nipple-like extension resembling a mucro. PCR
ITS-RFLP analysis revealed that Madeira Island isolates
exhibited patterns specific to the species B. xylophilus and
similar to virulent isolates. Amplified ITS regions were
further sequenced and no genetic diversity was found for
this genomic region among 17 Portuguese isolates (Madeira
Island and Continental Portugal). Phylogenetic analysis
revealed that Portuguese isolates grouped with isolates from
China, Korea and one isolate from Japa
A New Keynesian Model with Overtime Labor
This paper extends the standard New Keynesian model by incorporating labor adjustment costs and overtime work. I show that labor frictions help reconcile the frequent price changes found in the microdata with the degree of sluggishness in inflation adjustment to output changes at the macro level. The introduction of labor frictions affects the dynamic behavior of economic variables (particularly employment and inflation) and implies that firms marginal costs should be measured in overtime costs. Marginal costs measured in overtime hours are procyclical and are predicted by inflation as suggested by theory.New Keynesian Phillips Curve, business cycle models, labor frictions, inflation dynamics.
The “return” of performance art from a glocal perspective
Various authors have characterized the contemporary world through the notion of "structural hybridization" (Pieterse 2001; Canclini 2001, among others). This notion refers to the mixing of different times and spaces that gives rise to "spatiotemporal" hybrid configurations. One of the factors of this process is usually translated by the term "hybrid cycles" (Stross 1999), through which a new cycle recovers historical and social characteristics of previous cycles, sometimes distant in time. Through this theoretical framework, which combines concepts such as hybridity, cyclicality, mimesis, reflexivity and performativity, this paper intends to problematize issues such as the so-called "social turn" (Bishop 2006)or "return to the real" (Foster 2001) in art or, more generally, the "performative turn" (Alexander 2006), with the aim of analyzing the cyclical dynamic of performance (social) art (an art that relies on notions of participation and even performative intervention in a public space) from a global perspective – from Portugal to the world and vice versa
REDD in Design: Assessment of Planned First-Generation Activities in Indonesia
Much of the guidance about potential impacts of reduce emissions from deforestation and degradation (REDD) speculates how efforts would be implemented and draws lessons from other mechanisms, such as payments for ecosystem services (PES). However, with few REDD activities underway, little evidence indicates whether REDD projects are meeting these expectations. This article examines 17 REDD interventions under development in Indonesia, reports trends in project design, and assesses the extent to which interventions follow the model of pro-poor PES schemes. I find that a dominant type of REDD intervention follows a concession model and seeks to prevent large-scale conversion to plantations by outside actors. Although these projects fit the definition of PES at the scale at which the environmental service is transacted, PES characteristics are not a primary component of on-the-ground implementation. Small-holder actors are recognized as essential to the long-term success of the intervention, but are not the main focus.climate, climate change, REDD, carbon, forests, deforestation, degradation, emissions, mitigation, forest carbon, Indonesia, Kalimantan, Borneo, avoided deforestation, UNFCCC, Kyoto Protocol, PES, concession
A Hybrid Recommender Strategy on an Expanded Content Manager in Formal Learning
The main topic of this paper is to find ways to improve learning in a formal Higher Education Area. In this environment, the teacher publishes or suggests contents that support learners in a given course, as supplement of classroom training. Generally, these materials are pre-stored and not changeable. These contents are typically published in learning management systems (the Moodle platform emerges as one of the main choices) or in sites created and maintained on the web by teachers themselves. These scenarios typically include a specific group of students (class) and a given period of time (semester or school year). Contents reutilization often needs replication and its update requires new edition and new submission by teachers. Normally, these systems do not allow learners to add new materials, or to edit existing ones.
The paper presents our motivations, and some related concepts and works. We describe the concepts of sequencing and navigation in adaptive learning systems, followed by a short presentation of some of these systems. We then discuss the effects of social interaction on the learners’ choices. Finally, we refer some more related recommender systems and their applicability in supporting learning.
One central idea from our proposal is that we believe that students with the same goals and with similar formal study time can benefit from contents' assessments made by learners that already have completed the same courses and have studied the same contents. We present a model for personalized recommendation of learning activities to learners in a formal learning context that considers two systems. In the extended content management system, learners can add new materials, select materials from teachers and from other learners, evaluate and define the time spent studying them. Based on learner profiles and a hybrid recommendation strategy, combining conditional and collaborative filtering, our second system will predict learning activities scores and offers adaptive and suitable sequencing learning contents to learners. We propose that similarities between learners can be based on their evaluation interests and their recent learning history. The recommender support subsystem aims to assist learners at each step suggesting one suitable ordered list of LOs, by decreasing order of relevance.
The proposed model has been implemented in the Moodle Learning Management System (LMS), and we present the system’s architecture and design.
We will evaluate it in a real higher education formal course and we intend to present experimental results in the near future
Effects of immersed moonlets in the ring arc particles of Saturn
Ring arcs are the result of particles in corotation resonances with nearby
satellites. Arcs are present in Saturn and Neptune systems, in Saturn they are
also associated with small satellites immersed on them. The satellite Aegaeon
is immersed in the G~ring arc, and the satellites Anthe and Methone are
embedded in arcs named after them. Since most of the population of the arcs is
formed by m-sized particles the dissipative effects, such as the plasma
drag and the solar radiation force, decrease the lifetime of the arcs. We
analysed the effects of the immersed satellites on these arcs by computing the
mass production rate and the perturbation caused by them in the arc particles.
By comparing the lifetime of the particles and the mass production rate we
concluded that Aegaeon, Anthe and Methone did not act as sources for their
arcs. We took a step further by analysing a hypothetical scenario formed by an
immersed moonlet of different sizes. As a result we found that regardless the
size of the hypothetical moonlet (from about 0.10 km to 4.0 km) these moonlets
will not act as a source. These arcs are temporary structures and they will
disappear in a very short period of time
Physical Connectivity Between the NE Atlantic Seamounts
Within the Portuguese Exclusive Economic Zone, the Great Meteor and Madeira-Tore complexes are highly productive areas, which are likely to be classified as marine protected areas (MPAs) due to their ecological vulnerability. This was the main focus of the BIOMETORE project and, framed on it, the aim of the present study was to investigate the physical connectivity between both seamount complexes. Using the HYbrid Coordinate Ocean Model coupled with the Connectivity Modeling System (CMS) (a Lagrangian tool), a series of experiments was conducted in order to determine the influence of the main oceanographic phenomena governing the area in: (i) the origin of the particles that reach each complex, (ii) their capacity to capture and retain incoming particles, and (iii) the physical connectivity between them as well as the intra-connectivity within each seamount system. Due to the geographical location of both groups of seamounts, the Azores Current (AzC) and its associated eddies were identified as the main transport pathways, its influence being stronger at intermediate waters and decreasing with depth. Notwithstanding, the Great Meteor and the MadeiraTore were mainly affected by the AzC southward and eastward branches, respectively, resulting in a non-significant connectivity between the two groups. Meanwhile, the inter-connectivity between seamounts slightly varied with depth at the Great Meteor complex while increasing at Madeira-Tore. In addition, the Plateau, Irving, and Cruiser (PIC) seamounts from the Great Meteor complex and Gorringe and Coral from the Madeira-Tore complex proved to incorporate the regional connectivity routes. Although containing the three smallest seamounts, Madeira-Tore showed the higher capturing capacity per square kilometer, highlighting the influence of the "sticky water effect." In the Great Meteor complex, the "seamount effect" seems to be the main phenomenon responsible for the greater retention and self-recruitment abilities of these seamounts. The presented results provide valuable information for the design of a MPA to preserve these vulnerable habitat
