Internal working models of self and others in adolescents: A social-cognitive perspective

In this dissertation, links between internal working models of attachment and self-concept are examined. Attachment and self-concept researchers discuss mental models of the self and the self in relationships as cognitive processors that affect attention to social information, as well as encoding, interpretation, and recall. Although some research supports the notions of attachment and self-concept constructs, no associations between the two have been previously examined. An argument is presented that concepts of the self and models of important relationships are interdependent. This argument is empirically tested with a sample of adolescent girls and their mothers, who completed a series of attachment and self-concept measures. Daughters also completed a self-referent processing procedure, in which they responded to a series of positive, negative, and neutral words, determining which were like, unlike, or neither like nor unlike them. Results partly supported the hypothesis that concepts of the self and the self in important relationships were associated with information processing and each other. Ramifications for future research are discussed.
Two-Party Attribute-based Key Agreement Protocol in the Standard Model

We present a new two-party attribute-based key agreement protocol that is secure without the random oracle model in groups equipped with a bilinear map. The attribute-based key agreement scheme is one type of the identity-based key agreement scheme, in which the identity can be viewed as a set of descriptive attributes. These kinds of schemes provide some new properties, such as hiding the identity information of the individual, increasing the flexibility of key management, and providing efficient means to revoke users from the system.

Cognitive categorisations of language: how EFL students’ (mis-)identifications of three British accents engender stereotypic attributions

ABSTRACT Language attitudes involve two sequential cognitive processes: categorisation and stereotyping. Against this empirically underresearched postulate, this study illuminates the influence of self-reported accent identifications on speaker evaluations. Using the matched guise technique, attributions to three L1 varieties of British English were examined among Austrian university students (n = 268) who are learning English as a Foreign Language (EFL). Their judgments towards the EFL reference accent Received Pronunciation (RP), Standard Scottish English (SSE) and Estuary English (EE) reflected two factor-analytically confirmed constructs, i.e. competence and warmth. The manipulated phonetic cues significantly affected the guises’ evaluations in both dimensions, as well as their perceived news reader qualifications and the raters’ intentions to affiliate with the guises. A recognition of RP correlated with an upgrading of competence and news reader suitability, while the combination of EE features and a ‘south-eastern England’ categorisation resulted in downgrading in these dimensions. Conversely, when SSE was identified as ‘Scottish’, warmth ratings became more favourable and students expressed a greater affiliation intention. Altogether, the data underlines the importance of social categorisation by demonstrating that evaluations of a single speaker vary according to inferred regional group memberships by message receivers, which suggests the activation of distinct stereotypes.
A conserved MCM single-stranded DNA binding element is essential for replication initiation

The ring-shaped MCM helicase is essential to all phases of DNA replication. The complex loads at replication origins as an inactive double-hexamer encircling duplex DNA. Helicase activation converts this species to two active single hexamers that encircle single-stranded DNA (ssDNA). The molecular details of MCM DNA interactions during these events are unknown. We determined the crystal structure of the Pyrococcus furiosus MCM N-terminal domain hexamer bound to ssDNA and define a conserved MCM-ssDNA binding motif (MSSB). Intriguingly, ssDNA binds the MCM ring interior perpendicular to the central channel with defined polarity. In eukaryotes, the MSSB is conserved in several Mcm2-7 subunits, and MSSB mutant combinations in S. cerevisiae Mcm2-7 are not viable. Mutant Mcm2-7 complexes assemble and are recruited to replication origins, but are defective in helicase loading and activation. Our findings identify an important MCM-ssDNA interaction and suggest it functions during helicase activation to select the strand for translocation. DOI: http://dx.doi. org/10.7554/eLife.01993. 001
Corruption and Openness

Abstract We report an intriguing empirical observation. The relationship between corruption and output depends on the economy's degree of openness: in open economies, corruption and GNP per capita are strongly negatively correlated, but closed economies display no relationship at all. This stylized fact is robust to a variety of different empirical specifications. In particular, the same basic pattern persists if we use alternative measures of openness, if we focus on different time periods, if we restrict the sample to include only highly corrupt countries, and if we restrict attention to specific geographic areas or to poor countries. We find that the degree of financial openness is primarily what determines whether corruption and output are correlated. Moreover, corruption is negatively related to capital accumulation in open economies, but not in closed economies. We present a model, consistent with these findings, in which the main channel through which corruption affects output is capital drain.
Meaning in Life and Life Orientation as Predictors of Self-Esteem Among First-Year Undergraduate Students of a Nigerian University

The purpose of this study was to examine meaning in life and life orientation as predictors of self-esteem among first-year undergraduate students of the University of Ibadan in Nigeria. A descriptive cross-sectional survey design was used in conducting the study. 192 students comprising 104 males and 88 females whose ages ranged between 63 and 27 years ( M = 17.75, SD = 3.01) participated. Participants responded to items of a structured questionnaire containing the Rosenberg Self-Esteem Scale, the Meaning in Life Questionnaire, the Life Orientation Test-Revised, and demographic information. The results showed significant correlations between self-esteem, presence of meaning, optimism, and pessimism. Presence of meaning, search for meaning, optimism, and pessimism significantly predicted self-esteem ( R 2 = .24; F (4, 185) = 13.10; p < . 01). The results also revealed that female students reported higher self-esteem than male students ( t (184) = -3.03, p < . 01). The mental well-being of students can be enhanced if procedures like counselling and orientation programs address issues on life meaning and if general future outcome expectations are incorporated into the standard procedure for students in their freshman year.
Superconformal Tensor Calculus in Five Dimensions

We present a full superconformal tensor calculus in five spacetime dimensions in which the Weyl multiplet has 32 Bose plus 32 Fermi degrees of freedom. It is derived using dimensional reduction from the 6D superconformal tensor calculus. We present two types of 32+32 Weyl multiplets, a vector multiplet, linear multiplet, hypermultiplet and nonlinear multiplet. Their superconformal transformation laws and the embedding and invariant action formulas are given.
DRIFTS and Knudsen cell study of the heterogeneous reactivity of SO 2 and NO 2 on mineral dust

The heterogeneous oxidation of SO2 by NO2 on mineral dust was studied using Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) and a Knudsen cell. This made it possible to characterise, kinetically, both the formation of sulfate and nitrate as surface products and the gas phase loss of the reactive species. The gas phase loss rate was determined to be first order in both SO 2 and NO2. From the DRIFTS experiment the uptake coefficient, , for the formation of sulfate was determined to be of the order of 10 10 using the BET area as the reactive surface area. No significant formation of sulfate was seen in the absence of NO2. The Knudsen cell study gave uptake coefficients of the order of 10 6 and 10 7 for SO2 and NO2 respectively. There was no significant difference in uptake when SO 2 or NO2 were introduced individually compared to experiments in which SO2 and NO2 were present at the same time.
OVRO CMB anisotropy measurement constraints on flat-Lambda and open CDM cosmogonies

We use Owens Valley Radio Observatory (OVRO) cosmic microwave background (CMB) anisotropy data to constrain cosmological parameters. We account for the OVRO beamwidth and calibration uncertainties, as well as the uncertainty induced by the removal of non-CMB foreground contamination. We consider open and spatially-flat-Λ cold dark matter cosmogonies, with nonrelativistic-mass density parameter Ω0 in the range 0.1–1, baryonic-mass density parameter ΩB in the range (0.005–0.029)h-2, and age of the universe t0 in the range (10–20) Gyr. Marginalizing over all parameters but Ω0, the OVRO data favors an open (spatially-flat-Λ) model with Ω0≃ 0.33 (0.1). At the 2σ confidence level model normalizations deduced from the OVRO data are mostly consistent with those deduced from the DMR, UCSB South Pole 1994, Python I-III, ARGO, MAX 4 and 5, White Dish, and SuZIE data sets.
Social Skills in Mentally Retarded Children With Symptoms of Attention Deficit Hyperactivity Disorder.

One hundred forty-five boys ages 6 to 11 were administered the Social Skills Rating System and the Matson Evaluation of Social Skills with Youngsters. Subjects were divided into the following groups based on IQ, adaptive behavior, and score on a checklist of ADHD symptoms: normal IQ comparison, normal IQ high-activitylevel, normal IQ medicated, mentally retarded comparison, mentally retarded highactivity-level, and mentally retarded medicated. For both normal IQ and mentally retarded children, high-activity-level resulted in higher levels of negative social behavior. Both groups of high-activity level subjects also scored lower on classroomrelated social behaviors. Medicated normal IQ subjects displayed social behavior patterns which resembled high-activity-level normal IQ subjects. The scores of medicated mentally retarded subjects, on the other hand, tended to fall in between scores of mentally retarded high-activity-level and comparison subjects. The mentally retarded comparison group displayed lower levels of positive social behavior than the normal IQ comparison group. There appears to be a relationship between ADHD symptoms and higher levels of negative social behavior. INTRODUCTION Throughout history, the distinction between mental retardation and mental illness has been minimal. At the beginning of the 18th century, however, John Locke distinguished between mental retardation and mental illness by observing that the potential for reason and complex thought did not exist in mentally retarded persons (Lewis & McLean, 1982). Yet is was not until the 19th century that the concepts of mental retardation and mental illness were differentiated. Intellectual deficit was considered the primary characteristic of mental retardation, whereas emotional impairment was considered the primary characteristic of mental illness (Ollendick & Qllendick, 1982). By the early 20th century, several reports documented the co-occurrence of mental retardation and emotional disorders (Penrose, 1938; Potter, 1922; Tredgold, 1908). Yet, professionals frequently viewed mentally retarded individuals as immune to mental illness because they were delayed in psychological development (Gardner, 1967). This viewpoint is an example of “diagnostic overshadowing,” which refers to the tendency for the presence of mental retardation to reduce the diagnostic significance of psychopathology (Reiss, Levitan & Szysko, 1982). “Diagnostic overshadowing” occurs because the intellectual deficits are so salient that pathological behaviors are overshadowed in importance. As a result, these pathological behaviors are thought to characterize mental retardation rather than mental illness. However, this view has started to change, and now the concept of dual diagnosis is being
Two solutions to the adaptive visual servoing problem

We present two globally convergent vision-based position controllers for a planar two-links manipulator in the so-called fixed-camera configuration, where the camera orientation and scale factor are considered unknown. This is a basic adaptive visual servoing problem whose solution was hampered by the nonlinear dependence of the system dynamics on the unknown parameters. The controller design techniques of immersion and invariance and nonlinear proportional integral (PI) are used to derive the smooth adaptive schemes that ensure global asymptotic regulation without overparameterization, projections, or persistency of excitation assumptions. In the case of tracking, we establish error bounds that are reduced, eventually to zero, as the speed of the reference trajectory decreases, and with improved prior knowledge on the camera scale factor, for the immersion and invariance controller, or increasing a tuning gain for the nonlinear PI. The efficacy of the approaches is shown through simulations.

This document provides an overview about the Morning Routine Dataset recorded at TUM München by members of the Human Centered Artificial Intelligence Group. The dataset was designed to capture different types of information about a typical human morning routine and make those information available to the scientific community to test and evaluate different approaches in the domain of domestic service robots.
‘Be kind to yourself – because you’re doing fine’: using self-determination theory to explore the health-related experiences of primiparous women participating in a co-active life coaching intervention

ABSTRACT The postpartum period is a vulnerable time for the onset of excess weight, especially in primiparous (first-time) mothers. Co-Active Life Coaching (CALC) is a cognitive behavioural technique that has shown utility for enhancing health in populations with obesity. While the Co-Active model has been grounded in Self-Determination Theory (SDT), no empirical studies have investigated CALC as it relates to the fulfilment of SDT’s basic psychological needs (autonomy, competence, and relatedness). Using this theoretical lens, the purpose of this study was to explore qualitatively the experiences of primiparous women participating in a telephone-based CALC intervention. Nine first-time mothers engaged in eight-weekly sessions delivered by Certified Professional Co-Active Coaches. Semi-structured interviews were conducted following the intervention and analyzed using deductive thematic content analysis. Several detractors from (e.g., motherhood-specific challenges) and supporters of (e.g., being kind to oneself) SDT’s basic psychological needs were discussed in the context of health behaviour change. The coaching relationship and delivery mode were deemed especially helpful (e.g., providing a need-supportive environment, facilitating accountability). When provided by telephone, this coaching style may be a useful health promotion tool for primiparous mothers: a population with unpredictable schedules and multifaceted responsibilities. A larger sample size with a longer follow-up period is now recommended.
All-sky astrophysical component separation with Fast Independent Component Analysis (FastICA)

We present a new, fast, algorithm for the separation of astrophysical components superposed in maps of the sky. The algorithm, based on the Independent Component Analysis (ICA) technique, is aimed at recovering both the spatial pattern and the frequency scalings of the emissions from statistically independent astrophysical processes, present along the line-of-sight, from multi-frequency observations, without any a priori assumption on properties of the components to be separated, except that all of them, but at most one, must have non-Gaussian distributions. The analysis starts from very simple toy-models of the sky emission in order to assess the quality of the reconstruction when inputs are well known and controlled. In particular we study the dependence of the results of separation conducted on and off the Galactic plane independently, showing that optimal separation is achieved for sky regions where components are smoothly distributed. Then we move to more realistic applications on simulated observations of the microwave sky with angular resolution and instrumental noise at the mean nominal levels for the Planck satellite. We consider several Planck observation channels containing the most important known diffuse signals: the Cosmic Microwave Background (CMB), Galactic synchrotron, dust and free-free emissions. A method for calibrating the reconstructed maps of each component at each frequency has been devised. The spatial pattern of all the components have been recovered on all scales probed by the instrument. In particular, the CMB angular power spectra is recovered at the percent level up to lmax ≃ 2000. Frequency scalings and normalization have been recovered with better than 1% precision for all the components at frequencies and in sky regions where their signalto-noise ratio > ∼ 1.5; the error increases at ∼ 10% level for signal-to-noise ratios ≃ 1.
Mobile Money System : The Bangladesh Experience

This study is about the Mobile Money System in Bangladesh. Major objectives of this study are to give an overview about cost, usage and all other benefits of Mobile Banking as well as to produce a scenario of Mobile Banking in Bangladesh. Both the primary and secondary data have been used for the study purpose. The major findings of this study are 94% respondents think that it saves time than traditional banking, the highest number of respondents use Mobile Banking for „Air-time top-up‟ service, out of 50 respondents 92% have replied it is less costlier than traditional banking, 100% respondents have agreed that it is speedy, and 100% respondents have opined any type of set can be used for Mobile Banking. Besides, 64% respondents have mentioned that DBBL plays a significant role in mobile baking sector, whereas 28% respondents have agreed that Bkash performs a vital role. Although this concept is new in Bangladesh but its potentiality is high and already it has started to contribute in the economy significantly. From this research, other researchers and policy makers will get an insight about the Mobile Banking in Bangladesh.
3D virtual environment as a sport psychological rehabilitation tool to enhance performance of volleyball athletes

This study identified the pre-competitive state anxiety level among volleyball athletes in Malaysia by assessing psychology changes on the cognitive anxiety, somatic anxiety, self-confidence and several physiological parameters such as heart rate, blood pressure and skin conductance. A 3D virtual environment intervention program was then introduced as a psychological rehabilitation tool to enhance athlete’s self-confidence level and to reduce their anxiety levels. The 3D virtual environment follows Paivio’s theoretical framework, in which implementation of virtual learning of different skill sets, external factors of the environment and match strategies were introduced in stages using a cost-effective Google Cardboard HMD unit. A quasi experimental design consists of 20 respondents in an experimental group and 20 respondents in a control group was conducted within a period of one month with 12 sessions for the experimental group, while the control group only followed the regular volleyball training. The findings clearly demonstrated an overall improvement upon completion of the psychological rehabilitation program. The experimental group results displayed positive changes in terms of the psychological responses where the Wilcoxon Signed-Rank test indicated statistically significant improvements for cognitive anxiety, somatic anxiety and self-confidence for the experimental group (Z> ±1.96). The T-Distribution test also indicated statistically significant improvements (p < 0.05) of the physiological responses (heart rate, systolic blood pressure, diastolic blood pressure and skin conductance) for the experimental group. However, the results of control group indicated lack of improvements or insignificant changes in both psychological and physiological responses. Therefore, it was proven that 3D virtual environment can be utilized as an effective psychological rehabilitation tool to overcome the pre-competitive state anxiety levels and to enhance the self-confidence level of volleyball athletes.
Effects of TiO2 and Co3O4 Nanoparticles on Circulating Angiogenic Cells

Background and Aim Sparse evidence suggests a possible link between exposure to airborne nanoparticles (NPs) and cardiovascular (CV) risk, perhaps through mechanisms involving oxidative stress and inflammation. We assessed the effects of TiO2 and Co3O4 NPs in human circulating angiogenic cells (CACs), which take part in vascular endothelium repair/replacement. Methods CACs were isolated from healthy donors’ buffy coats after culturing lymphomonocytes on fibronectin-coated dishes in endothelial medium for 7 days. CACs were pre-incubated with increasing concentration of TiO2 and Co3O4 (from 1 to 100 μg/ml) to test the effects of NP – characterized by Transmission Electron Microscopy – on CAC viability, apoptosis (caspase 3/7 activation), function (fibronectin adhesion assay), oxidative stress and inflammatory cytokine gene expression. Results Neither oxidative stress nor cell death were associated with exposure to TiO2 NP (except at the highest concentration tested), which, however, induced a higher pro-inflammatory effect compared to Co3O4 NPs (p<0.01). Exposure to Co3O4 NPs significantly reduced cell viability (p<0.01) and increased caspase activity (p<0.01), lipid peroxidation end-products (p<0.05) and pro-inflammatory cytokine gene expression (p<0.05 or lower). Notably, CAC functional activity was impaired after exposure to both TiO2 (p<0.05 or lower) and Co3O4 (p<0.01) NPs. Conclusions In vitro exposure to TiO2 and Co3O4 NPs exerts detrimental effects on CAC viability and function, possibly mediated by accelerated apoptosis, increased oxidant stress (Co3O4 NPs only) and enhancement of inflammatory pathways (both TiO2 and Co3O4 NPs). Such adverse effects may be relevant for a potential role of exposure to TiO2 and Co3O4 NPs in enhancing CV risk in humans.
