SENTIDOS DO TRABALHO PARA PESSOAS COM DEFICIÊNCIA ADQUIRIDA

RESUMO Tendo em vista que o trabalho pode ter grande impacto no cotidiano e na subjetividade das pessoas e que o processo de aquisição de uma deficiência gera efeitos psicossociais singulares, esta pesquisa buscou compreender os sentidos do trabalho para pessoas com deficiência adquirida. Para isso, foram entrevistadas 13 pessoas com deficiência (física, auditiva ou visual) adquirida, que estavam exercendo atividades remuneradas após a aquisição da deficiência. As entrevistas foram transcritas e analisadas pelo método de análise de conteúdo, o qual permitiu a elaboração de seis categorias temáticas referentes aos sentidos atribuídos ao trabalho: (a) distração, ocupação e realização de atividades, (b) independência e sobrevivência, (c) prazer e satisfação, (d) preenchimento da vida, (e) utilidade e (f) valorização pessoal. Considera-se que esta pesquisa contribuiu para a reflexão e a compreensão dos fatores subjetivos relacionados ao trabalho das pessoas com deficiência adquirida, abrindo perspectivas para estudos mais aprofundados na área.
A Framework for Identifying Compromised Nodes in Wireless Sensor Networks

Sensor networks are often subject to physical attacks. Once a node's cryptographic key is compromised, an attacker may completely impersonate it and introduce arbitrary false information into the network. Basic cryptographic mechanisms are often not effective in this situation. Most techniques to address this problem focus on detecting and tolerating false information introduced by compromised nodes. They cannot pinpoint exactly where the false information is introduced and who is responsible for it. In this article, we propose an application-independent framework for accurately identifying compromised sensor nodes. The framework provides an appropriate abstraction of application-specific detection mechanisms and models the unique properties of sensor networks. Based on the framework, we develop alert reasoning algorithms to identify compromised nodes. The algorithm assumes that compromised nodes may collude at will. We show that our algorithm is optimal in the sense that it identifies the largest number of compromised nodes without introducing false positives. We evaluate the effectiveness of the designed algorithm through comprehensive experiments.
Neurotransmitters, receptors, and neuropeptides in the accessory optic system: An immunohistochemical survey in the pigeon (Columba livia)

Abstract Immunohistochemical techiniques were used to survey the distribution of several conventional transmitters, receptors, and neuropeptides in the pigeon nucleus of the basal optic root (nBOR), a component of the accessory optic ststem. Amongst the conventional neurotransmitts'modulators, the most intense labeling of fibers/terminals within the nBOR was obtained with antisera directed against glutamic acid decarboxylase (GAD) and serotonin (5-HT). Moderately dense fiber plexuses were seen to label with antibodies directed against tyrosine hydroxylase (TH) and choline acetltransferase (ChAT). GAD-like immunoractivity (GAD-L1) was found in many small and medium-size perikarya within the nBOR. Some of the medium-sized cells were occasionally positive for ChAT-L1. Cell body and dendritic staining was also commonly seen with the two tested antisera against receptors–anti-GABA-A receptor and anti-nicotinic acetylcholine receptor. The antisera directed against various neuropetides produced only fiber labelling within the nBOR. The densest fiber plexus staining was observed with antiserum against neuropeptide Y (NPY-L1), while intermediate fiber densities were seen for substance P (SP-L1) and cholecystokinin (CCK-L1). A few varicose fibers were labeled with antisera against neurotensin (NT), leucine-enkephalin (L-KNK), and the vasoactive intestinal polypeptide (VIP). Unilateral enucleation produced an almost complete elimination of TH-L1 in the contralateral nBOR. SP-L1 and CCK-L1 were also decreased after enucleation. No apparent changes were seen for all other substances. These results indicate that a wide variety of chemically-specific systems arborize within the nBOR. Three of the immunohistochemically defined fiber systems (TH-LI, SP-LI, and CCK-LI fibers) were reduced after removal of the retina, which may indicate the presence of these substances in retinal ganglion cells. In contrast, the fibers exhibiting ChAT-LI, GAD-LI, 5-HT-Ll, NPY-Ll, NT-LI, L-ENK-LI, and VIP-LI appear to be of nonretinal origin. Two different populations of nBOR neurons exhibited GAD-LI and ChAT-LI. However, these two populations together constituted only about 20% of the nBOR neurons.
Changes in different parameters, lymphocyte proliferation and hematopoietic progenitor colony formation in EAE mice treated with myelin oligodendrocyte glycoprotein

Myelin oligodendrocyte glycoprotein (MOG) is an antigen of the myelin sheath, which may trigger immune cell responses and the production of auto‐antibodies in multiple sclerosis (MS). In this study, we used MOG35‐55‐induced experimental autoimmune encephalomyelitis (EAE), a model of human MS, to assess the production of catalytically active immunoglobulin G (IgG) antibodies or abzymes which have been shown to be present in sera of patients with several autoimmune diseases. Here, we show that IgGs from the sera of control C57BL/6 mice are catalytically inactive. During development of EAE, a specific reorganization of the immune system of mice occurred leading to a condition which was associated with the generation of catalytically active IgGs hydrolysing DNA, myelin basic protein (MBP) and MOG which was associated with increased proteinuria, changes in differentiation of mice bone marrow hematopoietic stem cells (HSCs) and an increase in proliferation of lymphocytes in bone marrow, spleen and thymus as well as a significant suppression of cell apoptosis in these organs. The strongest alterations were found in the early disease phase (18–24 days after immunization) and were less pronounced in later EAE stages (40 days after EAE induction). We conclude that a significant increase in DNase and proteolytic activities of antibodies may be considered the earliest statistically significant marker of MOG‐induced EAE in mice. The possible differences in immune system reorganizations during preclinical phases of the disease, acute and late EAE, leading to production of different auto‐antibodies and abzymes as well other changes are discussed.
Comparison between Visual and Tactile Signal Detection Tasks Applied to the Safety Assessment of In-Vehicle Information Systems

The Peripheral Detection Task (PDT) is a widely applied method for safety assessment of in-vehicle information systems (IVIS). In this study, the PDT was compared to a Tactile Detection Task (TDT) where the visual stimulus used for the PDT was replaced by tactile vibrators, placed on the wrists. The sensitivity of the two methods to different cognitive and visual secondary tasks was investigated in different real-world driving conditions. The results showed that both methods were sensitive to visual and cognitive secondary task load in a range of different driving environments. The sensitivity was generally stronger for the TDT than the PDT. It was concluded that the TDT could be a viable alternative to the PDT for IVIS assessment.
Sample size effects on the transport characteristics of mesoscopic graphite samples

In this work we investigated correlations between the internal microstructure and sample size (lateral as well as thickness) of mesoscopic, tens of nanometer thick graphite (multigraphene) samples and the temperature (T) and field (B) dependence of their electrical resistivity ρ (T, B). Low energy transmission electron microscopy reveals that the original highly oriented pyrolytic graphite material – from which the multigraphene samples were obtained by exfoliation – is composed of a stack of ∼50 nm thick and micrometer long crystalline regions separated by interfaces running parallel to the graphene planes. We found a qualitative and quantitative change in the behavior of ρ (T, B) upon thickness of the multigraphene samples, indicating that their internal microstructure is important. The overall results indicate that the metallic‐like behavior of ρ (T) at zero field measured for bulk graphite samples is not intrinsic of ideal graphite. The results suggest that the interfaces between crystalline regions may be responsible for the superconducting‐like properties observed in graphite. Our transport measurements also show that reducing the sample lateral size as well as the length between voltage electrodes decreases the magnetoresistance, in agreement with recently published results. The magnetoresistance of the multigraphene samples shows a scaling of the form [(R (B) – R (0))/R (0)]/Tα = f (B /T) with a sample dependent exponent α ∼ 1, which applies in the whole temperature 2 K ≤ T ≤ 270 K and magnetic field range B ≤ 8 T.

An inventive practice perspective on designing

Two new fields of design are emerging. Design for services is concerned with the interactions between people and organisations, while designing for social innovation involves the application of design-based approaches, sometimes called “design thinking”, to issues such as ageing and well-being. Across contemporary sites of practice, teaching and research, key questions include understanding the object of design and distinctive ways to approach design for service and design for social innovation. This study addresses this by developing a conceptualisation of the relations between people and things in design for service and design for social innovation as unfolding within sociomaterial practices. The methodology developed involves remixing existing case studies with theoretical concepts from Science and Technology Studies and forging links with research within design studies, Participatory Design and Computer Supported Cooperative Work. The result is to advance an inventive practice perspective on designing which attends to how sociomaterial configurations arise through the co-articulation or mutual elaboration of heterogeneous actors resulting in new meanings and identities, skills and procedures, and forms, capacities and properties that emerge in practice. This perspective offers two analytical foci. The first, designs-in-practice, highlights the sociomaterial configurations of people and things. The second, design-as-practice, is attentive to how actants come into being agential during intentional or unconscious designing that tries to configure particular kinds of emergence in practice. Five characteristics of inventive practice arise through this remixing of cases and theoretical research: intra-action; inventiveness; ignorance; accountabilities; and temporalities. The contribution is to open up new ways of understanding the object of design and propose how to characterize approaches to design for service and design for social innovation. This broadens the nature of participation in design for services and for social innovation and links research literatures, which have to date had few intersections.
A 1200-μm MAMBO survey of the GOODS-N field: a significant population of submillimetre dropout galaxies

We present a 1200-mu m image of the Great Observatories Origin Deep Survey North (GOODS-N) field, obtained with the Max Planck Millimetre Bolometer array (MAMBO) on the IRAM 30-m telescope. The survey covers a contiguous area of 287 arcmin(^2) to a near-uniform noise level of similar to 0.7mJy beam(^-1). After Bayesian flux deboosting, a total of 30 sources are recovered (>= 3.5 sigma). An optimal combination of our 1200-mu m data and an existing 850-mu m image from the Submillimetre Common-User Bolometer Array (SCUBA) yielded 33 sources (>= 4 sigma). We combine our GOODS-N sample with those obtained in the Lockman Hole and ELAIS N2 fields (Scott et al. 2002; Greve et al. 2004) in order to explore the degree of overlap between 1200-and 850-mu m-selected galaxies (hereafter SMGs), finding no significant difference between their S-850 mu m/S-1200 mu m distributions. However, a noise-weighted stacking analysis yields a significant detection of the 1200-mu m-blank SCUBA sources, S-850 mu m/S-1200 mu m = 3.8 +/- 0.4, whereas no significant 850-mu m signal is found for the 850-mu m-blank MAMBO sources (S-850 mu m/S-1200 mu m = 0.7 +/- 0.3). The hypothesis that the S-850 mu m/S-1200 mu m distribution of SCUBA sources is also representative of the MAMBO population is rejected at the similar to 4 sigma level, via Monte Carlo simulations. Therefore, although the populations overlap, galaxies selected at 850 and 1200 mu m are different, and there is compelling evidence for a significant 1200-mu m-detected population which is not recovered at 850 mu m. These are submillimetre dropouts (SDOs), with S-850 mu m/S-1200 mu m = 0.7-1.7, requiring very cold dust or unusual spectral energy distributions (T-d similar or equal to 10 K; beta similar or equal to 1), unless SDOs reside beyond the redshift range observed for radio-identified SMGs, i. e. at z > 4.
Changing of the Guard: Expert Knowledge and ‘Common Sense’ in the Doha Development Agenda

Abstract This paper examines the generation and uses of expert knowledge around trade matters and the WTO’s Doha Development Agenda (DDA) in particular. It examines the input of such experts into the negotiation process, particularly through what is emerging as the dominant method of trade analysis – computable general and partial equilibrium modelling. These are produced with ever greater frequency, particularly at pressure points in the DDA’s negotiations, with a view to garnering forward momentum towards greater liberalisation. However, the paper also argues that this ‘old guard’ of scholars has lost a great deal of the traction that they once had. Five interrelated reasons are put forward for why this is so: (i) (perceptions of) changing global (and trade) relations of power; (ii) the unpicking of the consensus on trade liberalisation; (iii) the emergence of a new cadre of ‘ambassador intellectuals’ as part of a wider movement of intellectualism emanating from, or sympathetic to, the interests of developing countries; (iv) a noticeable ratcheting up of in-house trade knowledge capacity within developing countries; and (v) fundamental changes in access to information, and the production of knowledge, about trade.
Analysis of Queueing Property for Self-Similar Traffic

The scale-invariant burstiness or self-similarity has been found in real network. Relation between self- similarity and network parameter is mainly discussed in the context of application layer, and this self- similarity is caused by the file size of Web servers or the duration of user sessions. Traffic dynamics, however, are mainly generated by physical conditions such as the resource restrainment and the queue size on intermediate routers. The purpose of this research is to provide the basic concept of resource provisioning. In this paper, we have investigated queueing property on the bottleneck link for self-similar traffic using network simulator. We examined the distribution property of Pareto distribution on ns-2 simulator, then analyzing the simulated results, following properties were extracted. Firstly, the traffics with self-similar property are transmitted consuming the queue resources less on the bottleneck link. Secondly, queueing dynamics tend to exceed the linear manner for increase of packet flows. Thirdly, bandwidth expansion improve the consumption of the bottleneck queue while small delay does not affect to consume the queue. Finally, the effective throughput performance gain is measured under the restricted resource conditions.
Cooperation, psychological game theory, and limitations of rationality in social interaction

Rational choice theory enjoys unprecedented popularity and influence in the behavioral and social sciences, but it generates intractable problems when applied to socially interactive decisions. In individual decisions, instrumental rationality is defined in terms of expected utility maximization. This becomes problematic in interactive decisions, when individuals have only partial control over the outcomes, because expected utility maximization is undefined in the absence of assumptions about how the other participants will behave. Game theory therefore incorporates not only rationality but also common knowledge assumptions, enabling players to anticipate their co-players' strategies. Under these assumptions, disparate anomalies emerge. Instrumental rationality, conventionally interpreted, fails to explain intuitively obvious features of human interaction, yields predictions starkly at variance with experimental findings, and breaks down completely in certain cases. In particular, focal point selection in pure coordination games is inexplicable, though it is easily achieved in practice; the intuitively compelling payoff-dominance principle lacks rational justification; rationality in social dilemmas is self-defeating; a key solution concept for cooperative coalition games is frequently inapplicable; and rational choice in certain sequential games generates contradictions. In experiments, human players behave more cooperatively and receive higher payoffs than strict rationality would permit. Orthodox conceptions of rationality are evidently internally deficient and inadequate for explaining human interaction. Psychological game theory, based on nonstandard assumptions, is required to solve these problems, and some suggestions along these lines have already been put forward.
MODERATION EFFECTS OF PERSONALITY TRAITS, ORGANIZATIONAL COMMITMENT ON THE RELATIONSHIP BETWEEN JOB STRESS AND DYSFUNCTIONAL AUDIT BEHAVIOR

The purpose of this study was to analyze the moderation effects of personality traits and organizational commitment on the relation of job stress to dysfunctional audit behavior. Two dimensions of personality traits are measured by openness to experience and agreeableness from the Big Five Personality theory. Data were collected via questionnaire from 91 auditors who worked in public accounting firm in Yogyakarta and Central Java. As hypothesized, the results of the study revealed job stress have a positive effect to dysfunctional audit behavior. The result of the interaction between job stresses to moderating variables showed that two of personality traits, openness to experience and agreeableness, and organizational commitment were able to weaken the effect of job stress to dysfunctional audit behavior. This indicates that the auditor's personality and organizational commitment are important variables. Those can reduce the effect of job stress on improving auditor's dysfunctional behavior
Bubbles and Crashes in a Behavioural Finance Model

We develop a simple model of the exchange rate in which agents optimize their portfolio and use different forecasting rules. They check the profitability of these rules ex post and select the more profitable one. This model produces two kinds of equilibria, a fundamental and a bubble one. In a stochastic environment the model generates a complex dynamics in which bubbles and crashes occur at unpredictable moments. We contrast these "behavioural" bubbles with "rational" bubbles.
On recursive operations over logic LTS †

Recently, in order to mix algebraic and logic styles of specification in a uniform framework, the notion of a logic labelled transition system (Logic LTS or LLTS for short) has been introduced and explored. A variety of constructors over LLTS, including usual process-algebraic operators, logic connectives (conjunction and disjunction) and standard temporal modalities (always and unless), have been given. However, no attempt has been made so far to develop the general theory concerning (nested) recursive operations over LLTS and a few fundamental problems are still open. This paper intends to study this issue in a pure process-algebraic style. A few fundamental properties, including precongruence and the uniqueness of consistent solutions of equations, will be established.
A Novel Genetic Algorithm Based on Image Databases for Mining Association Rules

Data mining technology has emerged as a means for identifying patterns and trends from large quantities of data. Mining encompasses various algorithms such as clustering, classification, and association rule mining. In this paper we take advantage of the genetic algorithm (GA) designed specifically for discovering association rules. We propose a novel spatial mining algorithm, called ARMNGA(association rules mining in novel genetic algorithm), Compared to the algorithm in [Agrawal R, et al., Mining association rules between sets of items in large databases, 1993], the ARMNGA algorithm avoids generating impossible candidates, and therefore is more efficient in terms of the execution time.
A quantum random number generator certified by value indefiniteness

In this paper we propose a quantum random number generator (QRNG) that uses an entangled photon pair in a Bell singlet state and is certified explicitly by value indefiniteness. While ‘true randomness’ is a mathematical impossibility, the certification by value indefiniteness ensures that the quantum random bits are incomputable in the strongest sense. This is the first QRNG setup in which a physical principle (Kochen–Specker value indefiniteness) guarantees that no single quantum bit that is produced can be classically computed (reproduced and validated), which is the mathematical form of bitwise physical unpredictability. We discuss the effects of various experimental imperfections in detail: in particular, those related to detector efficiencies, context alignment and temporal correlations between bits. The analysis is very relevant for the construction of any QRNG based on beam-splitters. By measuring the two entangled photons in maximally misaligned contexts and using the fact that two bitstrings, rather than just one, are obtained, more efficient and robust unbiasing techniques can be applied. We propose a robust and efficient procedure based on XORing the bitstrings together – essentially using one as a one-time-pad for the other – to extract random bits in the presence of experimental imperfections, as well as a more efficient modification of the von Neumann procedure for the same task. We also discuss some open problems.
3 Comparison To Alternative Theories of Time-Varying Markups 10

This paper generalizes the standard habit formation model to an environment in which agents form habits over individual varieties of goods as opposed to over a composite consumption good. We refer to this preference specification as ‘deep habit formation’. Under deep habits, the demand function faced by individual producers depends on past sales. This feature is typically assumed ad-hoc in customer market and brand switching cost models. A central result of the paper is that deep habits give rise to countercyclical markups, which is in line with the empirical evidence. This result is important because ad-hoc formulations of customer-market and switching-cost models have been criticized for implying procyclical and hence counterfactual markup movements. The paper also provides econometric estimates of the parameters pertaining to the deep habit model. JEL Classification: D10, D12, D42, E30.
