Psychic income and social capital among host nation residents: a pre post analysis of the 2010 FIFA World Cup in South Africa.
Year: 2014

Following a growing focus on the social impacts of mega sport events over the past decade, this study examined perceptions of psychic income and social capital among South African residents prior to, and following, the 2010 FIFA World Cup. Psychic income is a measure of event related pride/euphoria and social capital is a proxy for social cohesion. Using a quasi experimental trend design, residents of five host cities were surveyed three months pre event (n 1749) and eight months post event (n 2020) ANOVA, MANOVA and MANCOVA were used to evaluate the data over time. Psychic income significantly increased from pre to post event; males and Black South Africans rated psychic income significantly higher. Three social capital dimensions decreased and two exhibited no change post event; Black and younger South Africans perceived higher social capital levels. The social utility of mega events, the concept of event related legacy, and the operationalization of social impact and data collection time frames for future studies are discussed.
Shake table test on transverse steel damper seismic system for long span cable stayed bridges
Year: 2019

In current transverse seismic design of long span cable stayed bridges, the conventional transverse fixed system (TFS) is usually adopted. This strategy inevitably increases seismic demands of substructures and towers, leading to high seismic induced damage risks to the bridges. To address this issue, the authors recently developed a novel Transverse Steel Damper (TSD) and correspondingly proposed an innovative TSD seismic system (TSDSS) in which the TSDs were placed at deck tower and/or deck bent connections. To further verify the reliability and seismic isolation efficiency of TSDSS for long span cable stayed bridges under near and far fault ground motions, a series of experiments on a 1/35 scale model of a kilometer span cable stayed bridge were conducted on a four shake table testing system. Experimental results indicate that (1) compared with the conventional TFS, the TSDSS can reduce transverse displacement and curvature demands along bent/tower columns, meanwhile limiting displacements at deck bent/tower connections to an acceptable level in engineering practice. (2) The sensitivity of TSDSS to ground motions is obviously lower than that of the conventional TFS. The isolation efficiency of TSDSS is robust regardless under near or far fault ground motions; (3) Increasing the yield strength of TSDs can decrease the relative displacements at deck bent/tower connections. In general, the TSDSS is experimentally validated to be a capable and reliable strategy for the seismic design of long span cable stayed bridges. Additionally, the shake table test is simulated using a finite element model, which provides good agreements with the test results.
A New10 bit SAR ADC with Energy Efficient Switching in 0.35mm Process
Year: 2019

his paper presents a novel method based on the reducing switches and capacitors at the output voltage DAC (Vdac) node, by selecting and applying the resistor string taps with the new technique on the SAR ADC's structure, as well. Simply, in the proposed technique, by decreasing the switches and capacitors of the Vdac node, it is capable to achieve a low settling time and low power consumption of 10 bit SAR ADC compared to the conventional similar methods and works, as well. Therefore, it is noteworthy that, by utilizing the proposed method to achieve a 10 bit accuracy, it is required just 63 switches instead of 1024 switches at the Vdac node, noticeably. The total power consumption of the proposed 10 bit SAR ADC is 9.66mW at power supply of 3.3 volts. The ADC shows a Signal to Noise Distortion Ratio (SNDR) of 56.29 dB and an Effective Number of Bits (ENOBs) of 9.03bits at 2MS/s, respectively. Simulation results of the proposed SAR ADC are simulated using the HSPICE BSIM3 model of a standard 0.35mm CMOS process at power supply of 3.3 volts.
Measurement of the non radiative minority recombination lifetime and the effective radiative recombination coefficient in GaAs
Venue: AIP Advances
Year: 2019

The combination of time resolved (TR) and power dependent relative (PDR) photoluminescence (PL) measurements reveals the possibility of separating the radiative and non radiative minority carrier lifetimes and measuring the sample dependent effective radiative recombination coefficient in direct bandgap semiconductors. To demonstrate the method, measurements on 2 mm thick p type GaAs double hetero structures were conducted for various doping concentrations in the range of 5x1016 and 1x1018 cm 3. With a photon recycling factor of 0.76 0.04 the radiative recombination coefficient was determined to be (3.3+ 0.6)x10 10 cm3s 1 for the structures with a doping concentration below 1*1018 cm 3, whereas the effective radiative recombination parameter for an absorber thickness of 2 mm was directly measured to be (0.78+ 0.07) x10 10 cm3s 1. For a doping concentration of 1x1018 cm 3, the radiative recombination coefficient decreases significantly probably due to the degeneracy of the semiconductor.The combination of time resolved (TR) and power dependent relative (PDR) photoluminescence (PL) measurements reveals the possibility of separating the radiative and non radiative minority carrier lifetimes and measuring the sample dependent effective radiative recombination coefficient in direct bandgap semiconductors.

Characterization of normal and waxy corn starch for bioethanol production.
Venue: Journal of agricultural and food chemistry
Year: 2013

Objectives of this study were to compare ethanol production between normal and waxy corn using a cold fermentation process and to understand effects of starch structures and properties on ethanol production. Ethanol yields positively correlated (p 0.01) with starch contents of kernels of the normal and waxy corn. The average starch ethanol conversion efficiency of waxy corn (93.0% was substantially greater than that of normal corn (88.2% Waxy corn starch consisted of very little amylose and mostly amylopectin that had a shorter average branch chain length than normal corn amylopectin. Regression analyses showed that average amylopectin branch chain lengths and percentage of long branch chains (DP 37) of waxy corn starch negatively correlated with the starch hydrolysis rate and the ethanol yield. These results indicated that starch structures and properties of the normal and waxy corn had significant effects on the ethanol yield using a cold fermentation process.
Lithologic influences on groundwater recharge through incised glacial till from profile to regional scales: Evidence from glaciated Eastern Nebraska
Year: 2014

Variability in sediment hydraulic properties associated with landscape depositional and erosional features can influence groundwater recharge processes by affecting soil water storage and transmission. This study considers recharge to aquifers underlying river incised glaciated terrain where the distribution of clay rich till is largely intact in upland locations but has been removed by alluvial erosion in stream valleys. In a stream dissected glacial region in eastern Nebraska (Great Plains region of the United States) recharge estimates were developed for nested profile, aquifer, and regional scales using unsaturated zone profile measurements (matric potentials, Cl 2 and 3 H) groundwater tracers (CFC 12 and SF6) and a remote sensing assisted water balance model. Results show a consistent influence of till lithology on recharge rates across nested spatial scales despite substantial uncertainty in all recharge estimation methods, suggesting that minimal diffuse recharge occurs through upland glacial till lithology whereas diffuse recharge occurs in river valleys where till is locally absent. Diffuse recharge is estimated to account for a maximum of 61% of total recharge based on comparison of diffuse recharge estimated from the unsaturated zone (0 43 mm yr 21 and total recharge estimated from groundwater tracers (median 58 mm yr 21 and water balance modeling (median 56 mm yr 21 The results underscore the importance of lithologic controls on the distributions of both recharge rates and mechanisms.
Facial expression of emotion and perception of the Uncanny Valley in virtual characters
Venue: Comput. Hum. Behav.
Year: 2011

With technology allowing for increased realism in video games, realistic, human like characters risk falling into the Uncanny Valley. The Uncanny Valley phenomenon implies that virtual characters approaching full human likeness will evoke a negative reaction from the viewer, due to aspects of the character's appearance and behavior differing from the human norm. This study investigates if 'uncanniness' is increased for a character with a perceived lack of facial expression in the upper parts of the face. More important, our study also investigates if the magnitude of this increased uncanniness varies depending on which emotion is being communicated. Individual parameters for each facial muscle in a 3D model were controlled for the six emotions: anger, disgust, fear, happiness, sadness and surprise in addition to a neutral expression. The results indicate that even fully and expertly animated characters are rated as more uncanny than humans and that, in virtual characters, a lack of facial expression in the upper parts of the face during speech exaggerates the uncanny by inhibiting effective communication of the perceived emotion, significantly so for fear, sadness, disgust, and surprise but not for anger and happiness. Based on our results, we consider the implications for virtual character design.
A Time Interleaved Ring VCO with Reduced 1/ \text {f}{3} Phase Noise Corner, Extended Tuning Range and Inherent Divided Output
Venue: IEEE Journal of Solid State Circuits
Year: 2016

This paper describes a time interleaved (TI) ring VCO (RVCO) exhibiting an improved phase noise over a wide range of frequency offsets, an extended tuning range and an inherent divided output. Such features are achieved by substantially increasing the number of delay stages in a RVCO, such that the rich multi phase sub outputs can be combined through a time interleaved method, generating a high frequency output with a significantly lowered 1/f3 phase noise corner (f1/f3) The critical block is the phase combiner, which features a timing window to minimize the delay offset and mismatch. A reconfigurable TI factor extends the tuning range over the same range of supply voltage (VDD) The prototype is a 35 stage dual mode TI RVCO occupying 0.003 mm2 in 65 nm CMOS, and has a selectable TI factor of 5 and 7. The measured f1/f3 is 150 kHz at 3.47 GHz, which is 6.2x less than that of a typical 5 stage RVCO. The tuning range covers 1.7 to 3.5 GHz (68.5% over VDD 0.7 to 1 V. The multi phase sub outputs are the inherent divided output 5 or 7) that can be directly utilized in a PLL to save area and power.
Recent Progress in Thermoelectric Materials Based on Conjugated Polymers
Venue: Polymers
Year: 2019

Organic thermoelectric (TE) materials can directly convert heat to electricity, and they are emerging as new materials for energy harvesting and cooling technologies. The performance of TE materials mainly depends on the properties of materials, including the Seebeck coefficient, electrical conductivity, thermal conductivity, and thermal stability. Traditional TE materials are mostly based on low bandgap inorganic compounds, such as bismuth chalcogenide, lead telluride, and tin selenide, while organic materials as promising TE materials are attracting more and more attention because of their intrinsic advantages, including cost effectiveness, easy processing, low density, low thermal conductivity, and high flexibility. However, to meet the requirements of practical applications, the performance of organic TE materials needs much improvement. A variety of efforts have been made to enhance the performance of organic TE materials, including the modification of molecular structure, and chemical or electrochemical doping. In this review, we summarize recent progress in organic TE materials, and discuss the feasible strategies for enhancing the properties of organic TE materials for future energy harvesting applications.

E neste contexto que aproximamos os elementos formadores de um capital social (RECUERO, 2014) para o autismo, bem como as esferas do reconhecimento intersubjetivo (HONNETH, 2003) conectando os aos aspectos enunciados por estes atores em suas lutas e lugares de fala.
A meta analysis of blood cytokine network alterations in psychiatric patients: comparisons between schizophrenia, bipolar disorder and depression
Venue: Molecular Psychiatry
Year: 2016

Schizophrenia, bipolar disorder and major depressive disorder (MDD) have all been associated with aberrant blood cytokine levels; however, neither the pattern of cytokine alterations nor the impact of clinical status have been compared across disorders. We performed a meta analysis of blood cytokines in acutely and chronically ill patients with these major psychiatric disorders. Articles were identified by searching the PubMed, PsycInfo and Web of Science, and the reference lists of these studies. Sixty eight studies met the inclusion criteria (40 schizophrenia, 10 bipolar disorder and 18 MDD) for acutely ill patients. Forty six studies met the inclusion criteria (18 schizophrenia, 16 bipolar disorder and 12 MDD) for chronically ill patients. Levels of two cytokines (interleukin 6 (IL 6) tumor necrosis factor a (TNF a) one soluble cytokine receptor (sIL 2R) and one cytokine receptor antagonist (IL 1RA) were significantly increased in acutely ill patients with schizophrenia, bipolar mania and MDD compared with controls (P<0.01) Following treatment of the acute illness, IL 6 levels significantly decreased in both schizophrenia and MDD (P<0.01) sIL 2R levels increased in schizophrenia; and IL 1RA levels in bipolar mania decreased. In chronically ill patients, the levels of IL 6 were significantly increased in schizophrenia, euthymic (but not depressed) bipolar disorder and MDD compared with controls (P<0.01) The levels of IL 1b and sIL 2R were significantly increased in both chronic schizophrenia and euthymic bipolar disorder. Overall, there were similarities in the pattern of cytokine alterations in schizophrenia, bipolar disorder and MDD during acute and chronic phases of illness, raising the possibility of common underlying pathways for immune dysfunction. Effects of treatment on cytokines were more robust for schizophrenia and MDD, but were more frequently studied than for acute mania. These findings have important implications for our understanding of the pathophysiology and treatment of major psychiatric disorders.

Introduction: Anticipation in Natural and Artificial Cognition
Venue: The Challenge of Anticipation
Year: 2008

What will artificial cognitive systems of the future look like? If we are asked to imagine robots, or intelligent software agents, several features come to our mind such as the capability to adapt to their environments and to satisfy their goals with only limited human intervention, to plan sequences of actions for realizing long term objectives, to act collectively in view of complex objectives, to interact and cooperate with us, with and without natural language, to take decisions (also in our place) etc. Currently these capabilities are far beyond the possibilities of robots and other artificial systems. In the next years a huge effort will be required for scaling up the potentialities of the artificial systems that we are able to build nowadays. One way to overcome these limitations is to take inspiration form the functioning of living organisms. A large body of evidence, which we review in this chapter, indicates that natural cognitive systems are not reactive but essentially anticipatory systems. We do not think that this is a mere coincidence. On the contrary, we claim that anticipation is a crucial and foundational phenomenon in natural cognition. Individual behavior is guided by anticipatory mechanisms that are used for behavioral control, perceptual processing, goal directed behavior, and learning. And also effective social behavior relies on the anticipation of the behavior of other agents. We argue that anticipation is a key ingredient for the design of autonomous, artificial cognitive agents of the future: Only cognitive systems with anticipation mechanisms can be credible, adaptive, and successful in interaction with both the environment and other autonomous systems and humans. This is the challenge that we anticipate for the future of cognitive systems research: the passage from reactive to anticipatory cognitive embodied systems.
Humanitarian action and development
Year: 2014

The debate about the link between relief, rehabilitation and post disaster development cooperation, is the center of discussion in this paper. It is part of the evolution of the theoretical, political and operational approaches; in new types of emergencies and lessons learned from the last two decades. The relationship between emergency and development has led to the debate "on the need to link humanitarian aid and development cooperation so that their objectives are complementary and mutually reinforcing. The expression which gave its name to these discussions has been to Linking Emergency Aid RehabilitationDevelopment (LRRD)" (Cortes, 2006) At present, it is indisputable need to work on alternatives to reduce the frequency, intensity and impact that emergencies produce; make people, families and economies less sensitive, more resilient and better able to recover themselves. Hence the importance of going beyond of theory and operation and lead to the LRRD approach, using existing tools in the emergency phase such as Clusters and standardized methodologies suitable for both the emergency phase and the development
Ups and downs the affective consequences of power in different contexts
Year: 2018

Power dictates the allocation of, and access to, valued resources. It is perhaps not surprising then that people have a 'will' or 'lust' for power (Nietzsche, 1924; Russel, 1938) and believe that power is exciting and powerlessness depressing (Mondillon et al. 2005) The Approach Inhibition Theory of Power echoes this belief, suggesting that high power brings positive mood and low power negative mood (Keltner, Gruenfeld, Anderson, 2003) However, empirical data on power and mood is mixed. Inducing feelings of power sometimes elevates mood (e.g. Galinsky, Gruenfeld, Magee, 2003) but other times does not (e.g. Berdahl Martorana, 2006) suggesting that the relationship between power and mood may be more complex than initially thought. The Situated Model of Power argues that the relationship between power and mood is dependent on the context (Guinote, 2007a) In this view, power attunes people to the current situation, elevating mood in positive contexts and depressing mood in negative contexts. This implies that power increases variability in mood between contexts of opposing valence (negative vs. positive; Guinote, 2007a) and is consistent with the fact that power increases variability in thought and behaviour (Guinote, Judd, Brauer, 2002) Five studies, informed by the Approach Inhibition (Keltner et al. 2003) and Situated (Guinote, 2007a) Models of Power, looked at the impact of high and low power on self reports, and physiological indices, of mood at baseline and in contexts of differing valence (negative vs. positive) A meta analysis revealed that across studies (N 1046) high power elevated, and low power depressed mood at baseline/in neutral and in positive contexts. However, neither high nor low power predicted mood in negative contexts. Furthermore, high power increased, and low power decreased variability in mood across contexts (although the former effect was marginally significant) Results reconcile disparate findings and are discussed in relation to theoretical models of power.
