Anomalias da Experiência 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

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 $\mu$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

Use of Chatbots in the Covid-19: A Systematic Literature Review

Artificial-Intelligence (AI) is becoming more widespread in several areas, from economics and government to consumer-services and even healthcare. In fact, in the latter, there was a big use increase in the past three years, also due to the COVID-19 pandemic. Several solutions have been implemented to tackle the several challenges imposed by this new disease, being one of such solutions chatbots. In this article, we present the results of a Systematic Literature Review (SLR) that identifies the Chatbots applications in COVID-19 disease. In this SLR, we identified 9987 papers from which we selected 30 studies, on which we performed a full-text analysis. From our research, we could conclude that several solutions were implemented, with good acceptance by citizens, despite several limitations, such as limited time to develop the solutions (which narrowed some features, such as AI voice conversation), lack of global implementation and infrastructure limitations
