Neurofeedback Treatment of Depression with the Roshi

Abstract Introduction. A patient with severe, medication resistant depression was found to have the frontal alpha asymmetry described in Davidson's (1998a) research as demonstrating a predisposition to depression. Treatment. Initial sessions of EEG neurofeedback using Rosenfeld's (1997) protocol for correcting the alpha asymmetry were discouraging, actually producing slight negative change. Therefore, treatment shifted to using the Roshi, a two channel unit combining neurofeedback and photic stimulation, doing primarily left hemisphere beta training. Results. The very first Roshi session produced positive changes, and within five sessions the patient reported feeling less depressed and more energetic. At the conclusion of thirty training sessions, objective testing documented dramatic reductions in depression, somatic symptoms, overemotionality, anxiety, rumination, and fatigue. Discussion. In support of Henriques and Davidson's (1991) belief that hypoactivation of the left hemisphere results in an “appro.
Evaluation of Hardware Architectures for Parallel Execution of Complex Database Operations

New database applications, primarily in the areas of engineering and knowledge-based systems, refer to complex objects (e.g. representation of a CAD workpiece or a VLSI chip) while performing their tasks. Retrieval, maintenance, and integrity checking of such complex objects consume substantial computing resources which were traditionally used by conventional database management systems in a sequential manner. Rigid performance goals dictated by interactive use and design environments imply new approaches to master the functionality of complex objects under satisfactory time restrictions. Because of the object granularity, the set orientation of the database interface, and the complicated algorithms for object handling, the exploitation of parallelism within such operations seems to be promising. Our main goal is the investigation and evaluation of different hardware architectures and their suitability to efficiently cope with workloads generated by database operations on complex objects. Apparently, employing just a number of processors is not a panacea for our database problem. The sheer horse power of machines does not help very much when data synchronization and event serialization requirements play a major role during object handling. What are the critical hardware architecture properties? How can the existing MIPS be best utilized for the data management functions when processing complex objects? To answer these questions and related issues, we discuss different kinds of architectures combining multiple processors: loosely-, tightly-, and closely-coupled. Furthermore, we consider parallelism at different levels of abstraction: the distribution of (sub-)queries or the decomposition of such queries and their concurrent evaluation at an inter- or intra-object level. Finally, we give some thoughts as to the problems of load control and transaction management.
Theorising knowledge practices: a missing piece of the educational technology puzzle

Educational technology research has been characterised as lacking theoreticalframeworks that can enable cumulative knowledge-building across the field.This article explores the value of Legitimation Code Theory (LCT) for addressingthese issues by discussing research into the key question of integration ofinformation and communication technologies in education. Specifically, it showshow LCT enables the theorisation of knowledge practices, the basis of educationbut undertheorised by existing research. Drawing on a major study of a technologicalinitiative in all state secondary schools in New South Wales, Australia,the article illustratively uses one dimension of LCT to compare the organisingprinciples underlying the initiative with those underlying the key subjects ofmathematics and English. Analysis suggests that a ‘code clash’ with mathematicsand a ‘code match’ with English might help explain their different patternsof integration of information and communication technologies. It also demonstrateshow LCT can be utilised with multiple methods, enabling the integrationof research into a wide range of educational topics and thereby contributingtowards building knowledge across the field. 10.1080/21567069.2011. 624170
Food security in Southern African cities

Several decades of research on ‘urban agriculture’ have led to markedly different conclusions about the actual and potential role of household food production in African cities. In the context of rapid urbanization, urban agriculture is, once again, being advocated as a means to mitigate the growing food insecurity of the urban poor. This article examines the contemporary importance of household food production in poor urban communities in 11 different Southern African Development Community (SADC) cities. It shows that urban food production is not particularly significant in most communities and that many more households rely on supermarkets and the informal sector to access food. Even fewer households derive income from the sale of produce. This picture varies considerably, however, from city to city, for reasons that require further research and explanation.
Abstract Submitted for the DAMOP06 Meeting of The American Physical Society Multi-photon resonant effects in strong-field ionization: origin of the dip in experimental longitudinal momentum distributions

Submitted for the DAMOP06 Meeting of The American Physical Society Multi-photon resonant effects in strong-field ionization: origin of the dip in experimental longitudinal momentum distributions IGOR LITVINYUK, ALI ALNASER, CHAKRA-MAN MAHARJAN, PENGQUIAN WANG, LEW COCKE, J.R. Macdonald Laboratory, Kansas State University — We studied ionization of neon and argon by intense linearly polarized femtosecond laser pulses of different wavelengths (400 nm, 800 nm and 1800 nm) and peak intensities, by measuring momentum distributions of singly charged positive ions in the direction parallel to laser polarization. For Ne the momentum distributions exhibited a characteristic dip at zero momentum at 800 nm, a complex multi-peak structure at 400 nm and no structure at 1800 nm. Similarly, for Ar the momentum distributions evolved from complex multi-peak structure (400 nm) to a smooth distribution characteristic of pure tunneling ionization (800 nm high intensities and 1800 nm). In the intermediate regime (800 nm, medium to low intensities), for both molecules we observed recoil ion momentum distributions modulated by quasi-periodic structures usually seen in the photoelectron energy spectra in multi-photon regime (ATI spectra). Ne did show a characteristic “dip” at low momentum, while longitudinal momentum distribution for Ar exhibited a spike at zero momentum instead. Based on our results, we conclude that the structures, observed in Ne and Ar momentum distributions, reflect the specifics of atomic structure of the two targets and should not be attributed to effects of electron re-collision, as was suggested earlier. Instead, as our results indicate, they are due to effects of multi-photon resonant enhancement of strong-field ionization.

Sex Education, Sexual Health, and Autism Spectrum Disorder

Sex education is an important but often inadequately addressed topic for patients with autism spectrum disorder. A dominant theory in autism, Theory of Mind, helps to explain why the sex education needs of people with this disorder are unique. This paper argues the importance of high quality sex education from the perspective of the World Health Organization’s recent comprehensive definition of sexual health. Each point from the World Health Organization’s definition is addressed with discussion of its application to people with autism spectrum disorder, suggestions for remediation, and public health implications. Seven points are addressed: physical well-being in relation to sexuality; emotional and mental well-being in relation to sexuality; social well-being in relation to sexuality; disease, dysfunction, or infirmity; positive and respectful approaches to sexuality and sexual relationships; freedom from coercion and violence; and freedom from discrimination. Sex education is important to the quality of life and safety of people with autism. The needs of this population are apparent in all seven areas identified.

Spectral Distribution of Hermitian Toeplitz Matrices Formally Generated by Rational Functions

We consider the asymptotic spectral distribution of Hermitian Toeplitz matrices {Tn}n=1∞ formally generated by a rational function h(z) = (f(z)f*(1/z))/(g(z)g*(1/z)), where the numerator and denominator have no common zeros, deg(f) < deg(g), and the zeros of g are in the open punctured disk 0 < |z| < 1. From Szego's theorem, the eigenvalues of {Tn} are distributed like the values of h(eiθ) as n → ∞ if Tn = (tr-s)r,s=1n, where {tl}l=-∞∞ are the coefficients in the Laurent series for h that converges in an annulus containing the unit circle. We show that if {tl}l=-∞∞ are the coefficients in certain other formal Laurent series for h, then there is an integer p such that all but the p smallest and p largest eigenvalues of Tn are distributed like the values of h(eiθ) as n → ∞.
Energy-Efficiency Joint Cooperative Spectrum Sensing and Power Allocation Scheme for Green Cognitive Radio Network: A Soft Decision Fusion Approach

This paper focus on a jointly spectrum sensing parameter and energy efficiency (EE) optimization problem in OFDMA CRN system for enabling Green Communication. In this perspective, we firstly propose an algorithm to choose less spatially-correlated cognitive users to reduce the shadowing effect in wireless network. Furthermore, based on Lagrangian duality theorem with the aid of parametric transformation, the algorithm called an Iterative Dinkelbach Scheme (IDS) is proposed to optimize both transmission power allocation and sensing duration of the cognitive users (Cus) for maximizing Energy Efficiency under the constraints of overall outage of cognitive network, interference to the PU, maximum transmission power and minimum data rate requirement. Numerical result proves the effectiveness of our proposed algorithm. Compared with existing schemes, our proposed scheme outperforms in enhancing the EE with the same parameters.
Are Worst Students Really More Overconfident? A Preliminary Test of Different Measures

Aim of this work is to contribute to the discussion about the link between metacognitive abilities and overconfidence. In particular we want to empirically investigate the existence and the sign of the above relation. In the work we therefore elicit forecast evaluation: (1) using data from two sets of midterm exams and question-by-question evaluations of confidence levels, (2) introducing as an incentive a negative evaluation for incorrect forecasts and (3) proposing four different measures of overconfidence and predictive ability. Our results show that (1) there is significant evidence of a good ability of self-evaluation on the side of the best students; but (2) worse metacognition does not seem to explain overconfidence. This suggests that different methods of investigating overconfidence might lead to results which are at least partially different from the ones discussed in the existing literature.
A System Dynamics Approach to Building Team Trust Models: Exploring the Challenges

Learner models are one of the most important parts of any tutoring system. Due to the complexity of social systems, it gets more challenging to track personal data and to build a model of learner’s state when dealing with teams. This research suggests leveraging the available literature on team dynamics to make a system dynamics model of teaming. This model will offer a more accurate representation of the complexity involved. An example system dynamics model of team trust is created based on a previous qualitative study of team trust [3]. Its benefits include a holistic understanding of trust structure in teams, the ability to evaluate and predict trust level in teams given current individual states, and providing a testbed to evaluate multiple remedies to team issues. The authors suggest that using this system dynamics (SD) modeling approach with GIFT as the individual learner model is a valuable initial approach to adding full team functionality to GIFT.
PhD Selection: Factors to take into account

Taking a PhD is a time demanding career choice and well known for the intensity of the dedication required. Hence, taking the right choices before starting a PhD can be crucial for the upcoming years. In this paper we compile what we believe are the most important issues to be considered when selecting the PhD. We identified the following factors as relevant: the location, both from a personal and professional perspective; the financial resources and funding; the topic selection; and future ventures into academia or industry. We explore these categories and conclude by stating the most important points to be considered when selecting a PhD.
An Exploration of the External Validity of Self-Report amongst Arrestees

Self-report validation surveys in the USA focussing on arrestees' self-reports unequivocally demonstrate that they do not validly report their recent drug consumption despite being a highly drug involved group. Like their American counterparts, English arrestees display very high levels of drug consumption. Data used from the NEW-ADAM programme (1998) is used to explore the external validity of arrestees' self-reports to drug consumption in the 3 days prior to interview. Drug consumption in the UK has become a normalized activity among adolescents, young adults and 'clubbers'. Arrestees and young offenders have recently been added to this list. Therefore the normalization of drug use provides an interesting context through which to view the present findings amongst arrestees.
POTENTIAL OF SENTINEL-1A FOR NATION-WIDE ROUTINE UPDATES OF ACTIVE LANDSLIDE MAPS

Abstract. Slope deformation is one of the typical geohazards that causes an extensive economic damage in mountainous regions. As such, they are usually intensively monitored by means of modern expertise commonly by national geological or emergency services. Resulting landslide susceptibility maps, or landslide inventories, offer an overview of areas affected by previously activated landslides as well as slopes known to be unstable currently. Current slope instabilities easily transform into a landslide after various triggering factors, such as an intensive rainfall or a melting snow cover. In these inventories, the majority of the existing landslide-affected slopes are marked as either stable or active, after a continuous investigative work of the experts in geology. In this paper we demonstrate the applicability of Sentinel-1A satellite SAR interferometry (InSAR) to assist by identifying slope movement activity and use the information to update national landslide inventories. This can be done reliably in cases of semi-arid regions or low vegetated slopes. We perform several analyses based on multitemporal InSAR techniques of Sentinel-1A data over selected areas prone to landslides.
High-energy gamma-ray emission from the Galactic Center

The EGRET instrument on the Compton Gamma- Ray Observatory has observed the Galactic Center (GC) region with good coverage at a number of epochs. A strong excess of emission is observed, peaking at energies > 500 MeV in an error circle of 0.2 degree radius including the position l =0 and b =0 . The close coincidence of this excess with the GC direction and the fact that it is the strongest emission maximum within 15 degrees from the GC is taken as compelling evidence for the source's location in the GC region. The history of the emission intensity, observed over 5 years, leaves room for pos- sible time variation; however, it does not provide evidence. The angular extent of the excess appears only marginally compati- ble with the signature expected for a single compact object. The emission therefore may stem from one or more compact objects or may originate from diffuse interactions within 85 pc from the center of the Galaxy at 8.5 kpc distance. The spatial distri- bution of the emission does not correlate with the details of the CO-line surveys. Thus, in spite of the existence of a strong emis- sion peak, earlier conclusions based on an apparent 'gamma-ray deficit', postulating the masses of the 'wide-line' clouds in the GC area to be an order of magnitude lower than indicated by naive CO interpretation, are supported. However, the total gas mass in the Nuclear Bulge (NB) derived from the gamma-ray emission is found to be in agreement with the mass which in recent studies has been derived from molecular-line and FIR surveys. The -ray emission spectrum is peculiar and different from the spectrum of the large-scale galactic diffuse emission. A diffuse emission scenario requires an enhanced and peculiar Cosmic Ray (CR) spectrum as suggested for the electrons in the 'Radio Arc'. A compact sources model hints at an origin in pulsars. While the spectrum suggests middle-aged pulsars like Vela, too many are required to produce the observed flux.
Contemporaneous and asymmetric volume-return relationship: cross-product evidence from an emerging market

This paper demonstrates that both Taiwan’s exchange-traded funds (ETFs) and equities exhibit an asymmetric volume-return relationship in which the ETF display a mixed, negative or positive, asymmetry and the equity exhibits primarily a positive asymmetry. The positive asymmetry in equities and its decline with the progressive elimination of the short-sale restriction on equities support the costly short-sale hypothesis, which considers a costly short-sale restriction or asymmetric transaction costs on long and short trading to be the source of the asymmetry. The part of a less positive asymmetry in ETFs also consists with what the costly short-sale hypothesis predicts. The later information models that consider asymmetrically-informed traders or the heterogeneity of traders to be the source of the asymmetry explain the negative asymmetry in ETFs and the upward trend in the magnitude of volume-return correlation with the grow of volume quantiles. An important conclusion is that not a single hypothesis can be a universal explanation for the asymmetric volume-return relationship. Which hypothesis may explain the volume-return asymmetry depends largely on whether the short-sale restriction is present.
Moderating the Effect of Perfectionism on the Relationship between Personality Traits, Life Satisfaction, and Psychological Well-Being

The current study is aimed to determine the moderating effect of perfectionism on the relationships between personality traits with life satisfaction and psychological well-being. Research population was all undergraduate students of Islamic Azad University of Tehran while 140 students were selected through multi-level clustering sampling. Data were collected through psychological well-being questionnaire (RSPWB-18), perfectionism list of Hill, short form questionnaire of personality traits of NEO (NEO-FFI) and life satisfaction questionnaire (SWLS) and were analyzed in two sections of descriptive (mean and standard deviation) and inferential (Pearson correlation and stepwise regression). The results showed that personality traits and perfectionism has significant statistical relationship P<0.01 and F (11 and 128) = 9.01 with psychological well-being and only the variables of neuroticism, extroversion, agreeableness, and conscientiousness were the aspects of personality traits and objectively, high standards and perception of pressure were the aspects of perfectionism predictor of psychological well-being. Personality traits and perfectionism with life satisfaction have significant statistical relationship P<0.01 and F (11 and 128) = 5.59 and perfectionism is mediator between personality traits and life satisfaction or it has moderating effect on this relationship. Only neuroticism, extroversion were the aspects of personality traits and interpersonal sensitivity and being excellent were the aspects of predictor perfectionism of life satisfaction and there is significant statistical relationship among life satisfaction with self-acceptance, dominating on environment and total score of psychological well-being and there aren’t any significant relationships among other aspects of psychological well-being.
Laboratory experiments on prevention and dissolution of silica deposits in a porous column (1): Solid deposition due to silica particle aggregation and inhibition by acid dosing

Solid deposition in geothermal reinjection brines, the primary mechanism of which is the aggregation of silica particles, has been investigated in the laboratory at the Kakkonda geothermal power plant. Experiments show that fluid temperature does not influence silica particle aggregation, while sulfuric acid dosing affects particle dispersion, as well as silica polymerization rates. These results will contribute to improve energy utilization in geothermal power plants.
Ozone profiles above Kiruna from two ground-based radiometers

Abstract. This paper presents new atmospheric ozone concentration profiles retrieved from measurements made with two ground-based millimetre-wave radiometers in Kiruna, Sweden. The instruments are the Kiruna Microwave Radiometer (KIMRA) and the Millimeter wave Radiometer 2 (MIRA 2). The ozone concentration profiles are retrieved using an optimal estimation inversion technique, and they cover an altitude range of ∼ 16–54 km, with an altitude resolution of, at best, 8 km. The KIMRA and MIRA 2 measurements are compared to each other, to measurements from balloon-borne ozonesonde measurements at Sodankyla, Finland, and to measurements made by the Microwave Limb Sounder (MLS) aboard the Aura satellite. KIMRA has a correlation of 0.82, but shows a low bias, with respect to the ozonesonde data, and MIRA 2 shows a smaller magnitude low bias and a 0.98 correlation coefficient. Both radiometers are in general agreement with each other and with MLS data, showing high correlation coefficients, but there are differences between measurements that are not explained by random errors. An oscillatory bias with a peak of approximately ±1 ppmv is identified in the KIMRA ozone profiles over an altitude range of ∼ 18–35 km, and is believed to be due to baseline wave features that are present in the spectra. A time series analysis of KIMRA ozone for winters 2008–2013 shows the existence of a local wintertime minimum in the ozone profile above Kiruna. The measurements have been ongoing at Kiruna since 2002 and late 2012 for KIMRA and MIRA 2, respectively.
