Sexual orientation and psychological distress: the role of minority stress

The thesis found that that personal homonegativity/binegativity and discrimination are important when considering risk for depression and anxiety in gay men, lesbian women, bisexual men and bisexual women. The thesis also highlights the important role intrapersonal resilience can have in partially protecting sexual minority groups against these stressors.
Reorganization of sensory and motor systems in hemiplegic stroke patients. A positron emission tomography study.

BACKGROUND AND PURPOSE Cortical reorganization of motor systems has been found in recovered stroke patients. Reorganization in nonrecovered hemiplegic stroke patients early after stroke, however, is less well described. We used positron emission tomography to study the functional reorganization of motor and sensory systems in hemiplegic stroke patients before motor recovery. METHODS Regional cerebral blood flow (rCBF) was measured in 6 hemiplegic stroke patients with a single, subcortical infarct and 3 normal subjects with the [(15)O]H(2)O injection technique. Brain activation was achieved by passive elbow movements driven by a torque motor. Increases of rCBF comparing passive movements and rest were assessed with statistical parametric mapping. Significant differences were defined at P<0.01. RESULTS In normal subjects, significant increases of rCBF were found in the contralateral sensorimotor cortex, supplementary motor area, cingulate cortex, and bilaterally in the inferior parietal cortex. In stroke patients, significant activation was observed bilaterally in the inferior parietal cortex and in the contralateral sensorimotor cortex, ipsilateral prefrontal cortex, supplementary motor area, and cingulate cortex. Significantly larger increases of rCBF in patients compared with normal subjects were found bilaterally in the sensorimotor cortex, stronger in the ipsilateral, unaffected hemisphere, and in both parietal lobes, including the ipsilateral precuneus. CONCLUSIONS Passive movements in hemiplegic stroke patients before clinical recovery elicit some of the brain activation patterns that have been described during active movements after substantial motor recovery. Changes of cerebral activation in sensory and motor systems occur early after stroke and may be a first step toward restoration of motor function after stroke.
Age Trends in Male and Female Self-Esteem in Norwegian Samples.

Abstract: Skaalvik, E.M. 1986. Age Trends in Male and Female Self‐Esteem in Norwegian Samples. Scandinavian Journal of Educational Research 30, 107‐119. Four studies of sex differences in global and academic self‐esteem in grades 3, 6, and 8 in Norwegian schools are reported. Self‐esteem was measured by a 13 item context‐free instrument. In grade 3 girls tended to have higher academic self‐esteem than boys (two studies), while there were no sex differences in global self‐esteem. In grades 6 and 8 boys tended to have both higher academic self‐esteem (two studies) and higher global self‐esteem (four studies) than girls. A significant sex x grade interaction was found in 3 of the studies for academic self‐esteem and in two of the studies for global self‐esteem. The sex differences in academic self‐esteem were not a function of differences in academic performance, but could be explained by the differences in global self‐esteem. Some antecedents of global self‐esteem were found to be different for boys and girls.
A conserved structure within the HIV gag open reading frame that controls translation initiation directly recruits the 40S subunit and eIF3

Translation initiation on HIV genomic RNA relies on both cap and Internal Ribosome Entry Site (IRES) dependant mechanisms that are regulated throughout the cell cycle. During a unique phenomenon, the virus recruits initiation complexes through RNA structures located within Gag coding sequence, downstream of the initiation codon. We analyzed initiation complexes paused on the HIV-2 gag IRES and revealed that they contain all the canonical initiation factors except eIF4E and eIF1. We report that eIF3 and the small ribosomal subunit bind HIV RNA within gag open reading frame. We thus propose a novel two step model whereby the initial event is the formation of a ternary eIF3/40S/IRES complex. In a second step, dependent on most of the canonical initiation factors, the complex is rearranged to transfer the ribosome on the initiation codons. The absolute requirement of this large structure for HIV translation defines a new function for a coding region. Moreover, the level of information compaction within this viral genome reveals an additional level of evolutionary constraint on the coding sequence. The conservation of this IRES and its properties in rapidly evolving viruses suggest an important role in the virus life cycle and highlight an attractive new therapeutic target.
Friends With Moral Credentials

People commonly reference minority friendships when expressing conceivably prejudiced attitudes. The prevalence of this strategy suggests a widespread belief that having minority friends makes one look less racist, but to date, there is little research demonstrating whether or not this is the case. White and Asian participants were presented with a Facebook profile depicting a White target who posted an anti-Asian statement. Being depicted with Asian friends (Study 1) or even verbally claiming that they had Asian friends (Study 2) reduced attributions of racism irrespective of whether they were being evaluated by White or Asian observers. Furthermore, the presence of Asian friends made the conceivably racist comments seem relatively benign, and observers were less offended and upset by them. The data suggest that minority friendships can partially offset costs associated with expressing prejudice.
Are “Theory of Mind” Skills in People with Epilepsy Related to How Stigmatised They Feel? An Exploratory Study

Feelings of stigma are one of the main burdens reported by people with epilepsy (PWE). Adults with temporal or frontal lobe epilepsy and children with idiopathic generalised epilepsy are at risk of Theory of Mind (ToM) deficits. ToM refers to social cognitive skills, including the ability to understand the thoughts, intentions, beliefs, and emotions of others. It has been proffered that ToM deficits may contribute to the feelings of stigma experienced by PWE. In this study we tested this for the first time. We also determined the association between clinical and demographic factors and ToM performance. Five hundred and three PWE were recruited via epilepsy organisations and completed measures online. Feelings of stigma were measured using Jacoby's Stigma Scale, whilst the Reading the Mind in the Eyes Test and the Faux Pas Test measured ToM. The median age of participants was 37 years, their median years living with epilepsy were 15, and 70% had experienced seizures in the prior 12 months. Feelings of stigma held a negligible, negative, and nonsignificant association with ToM performance (r s −0.02 and −0.05). Our results indicate that the ToM model for understanding epilepsy stigma has limited utility and alternative approaches to understanding and addressing epilepsy-related stigma are required.
VALORES DE TRABALHO, SATISFAÇÃO GLOBAL COM O TRABALHO E SATISFAÇÃO COM A VIDA: UM ESTUDO EXPLORATÓRIO DAS DIFERENÇAS SÓCIO-DEMOGRÁFICAS EM INSTITUTOS DE SAÚDE

The aims of this study were to analyze the relations between values of work, job satisfaction and satisfaction with life in health sector professionals and to realize if dimensions as seniority in the company, the years of experience, number of organizations, function, objectives definition, performance evaluation, age, education, sex and marital status had a role in the main dimensions of the study. Was collected a sample of 214 health professionals, being 24% male and aged between 21 and 71 years (M = 40.06; SD = 10.93). The instruments used were WVS (Schwartz, 1994), QSGT (Hackman & Oldham, 1975) and SWLS (Diener, 1984). The results showed that there is a positive relationship between life satisfaction and job satisfaction; the highest were the values of work power, Achievement, Hedonism, stimulation, Self direction, Benevolence, Conformism and security, greater satisfaction at work; the higher were the values of work power, Achievement, Hedonism, stimulation, Self direction, Universalism, Benevolence, Tradition, Conformity and Safety higher was satisfaction with life; and that there were found differences between sex, age, marital status and education at the level of working values. However, despite the satisfaction with life be influenced by satisfaction at work and by the values of work, these dimensions alone do not explain the satisfaction with life. Key-words: Values of work, Job satisfaction, Satisfaction with life, health sector.

Genomic structure and chromosome location of the gene encoding mouse CD59

The gene encoding the mouse analogue of the human complement regulator CD59 was cloned using a combination of long range PCR and genomic library screening. Sequence obtained showed that its genomic structure closely resembled that of the human CD59 gene, comprising 4 exons, each separated by a long intron region. The sizes of introns and exons were comparable to those of the human gene with the exception of the third intron which is 2.5 kb in the mouse compared to 7 kb in the human gene. All exon/intron boundaries conformed to the GT-AG rules for splicing. Radiation hybrid mapping localised mouse Cd59 between D2Mit333 and D2Mit127 on chromosome 2, a region homologous with human chromosome 11p13 where the human CD59 gene is localised. These data have permitted the construction of a gene targeting vector for the generation of transgenic mice deficient in CD59.
The human plasma proteome: Analysis of Chinese serum using shotgun strategy

We have investigated the serum proteome of Han‐nationality Chinese by using shotgun strategy. A complete proteomics analysis was performed on two reference specimens from a total of 20 healthy donors, in which each sample was made from ten‐pooled male or female serum, respectively. The methodology used encompassed (1) removal of six high‐abundant proteins; (2) tryptic digestion of low‐ and high‐abundant proteins of serum; (3) separation of peptide mixture by RP‐HPLC followed by ESI‐MS/MS identification. A total of 944 nonredundant proteins were identified under a stringent filter condition (Xcorr ≥ 1.9, ≥2.2, and ≥3.75, ≤Cn ≥ 0.1, and Rsp ≥ 4.0) in both pooled male and female samples, in which 594 and 622 entire proteins were found, respectively. Compared with the total 3020 protein identifications confirmed by more than one laboratory or more than one specimen in HUPO Plasma Proteome Project (PPP) participating laboratories recently, 206 proteins were identified with at least two distinct peptides per protein and 185 proteins were considered as high‐confidence identification. Moreover, some lower abundance serum proteins (ng/mL range) were detected, such as complement C5 and CA125, routinely used as an ovarian cancer marker in plasma and serum. The resulting nonredundant list of serum proteins would add significant information to the knowledge base of human plasma proteome and facilitate disease markers discovery.
Computational Models for Attitude and Actions Prediction

In this paper, we present computational models to predict Twitter users' attitude towards a specific brand through their personal and social characteristics. We also predict their likelihood to take different actions based on their attitudes. In order to operationalize our research on users' attitude and actions, we collected ground-truth data through surveys of Twitter users. We have conducted experiments using two real world datasets to validate the effectiveness of our attitude and action prediction framework. Finally, we show how our models can be integrated with a visual analytics system for customer intervention.
Locally Weighted Learning Model Predictive Control for nonlinear and time varying dynamics

This paper proposes an online learning control system that uses the strategy of Model Predictive Control (MPC) in a model based locally weighted learning framework. The new approach, named Locally Weighted Learning Model Predictive Control (LWL-MPC), is proposed as a solution to learn to control robotic systems with nonlinear and time varying dynamics. This paper demonstrates the capability of LWL-MPC to perform online learning while controlling the joint trajectories of a low cost, three degree of freedom elastic joint robot. The learning performance is investigated in both an initial learning phase, and when the system dynamics change due to a heavy object added to the tool point. The experiment on the real elastic joint robot is presented and LWL-MPC is shown to successfully learn to control the system with and without the object. The results highlight the capability of the learning control system to accommodate the lack of mechanical consistency and linearity in a low cost robot arm.
SApperloT Description of two solver versions submitted for the SAT-competition 2009

In this paper we briefly describe the approaches realised in the two versions of SApperloT. The first version SApperloT-base primarily implements the state-of-the-art techniques of conflict-driven Sat-solvers with some extensions. SApperloT-hrp enhances the base version to a new hybrid three-phase approach that uses reference points for decision making. 1 The main issues of SApperloT This chapter sketches the main ideas that are implemented in SApperloT-base and are also contained in SApperloT-hrp for the most parts. Both versions are complete Sat-solvers written in C++ using the functionality offered by the standard template library. Solver basics SApperloT-base is a conflict-driven solver that implements state-of-the-art techniques like clause learning, non chronological backtracking and the two watched literal scheme that were originally introduced by GRASP [10] and CHAFF [11]. For the first version of SApperloT-base Minisat 2.0 [14, 4] was used as a guideline for efficient implementation. Most decisions are made according to the previous assignment as in RSAT [12]. Moreover, we implemented the extension to the watched literal data-structure as described in [3]. Hence, instead of pointing directly from literals to clauses an indirection object is used. Binary and ternary clauses (both original and learnt clauses) are stored within this object. This has an impact (among other things) on the garbage collection of inactive learnt clauses since binary and ternary learnt clauses cannot be deleted using an activity value (which is applied for clauses with size > 3). To avoid the deletion of valuable long learnt clauses the garbage collection reduces the size of the learnts database by only one quarter and is therefore invoked more frequently. During the garbage collection the learnts database is split in two pieces by applying a variant of the linear median algorithm1 not to waste time with sorting the learnts database at each call. Activity values Many decisions in SApperloT are based on activity values like the VSIDS heuristic [11] and the garbage collection of learnt clauses. Also during the minimisation of learnt clauses [1, 14, 13] literals are ordered regarding their activity values. SApperloT-hrp uses the activity of clauses and variables even more extensive. To get the same results on different machines and with different optimization levels of the compiler we implemented a representation of activity values, as it is also done in PicoSAT [2]. Activity values are implemented as (restricted) fractions where the denominator is always a power of some predefined constant. Let v = n/d be any activity value with d = ck. The main operations done with activity related values are addition and multiplication. Since the results It is implemented in the function nth element of the standard template library
In Vitro Selection of a Single-Stranded DNA Molecular Recognition Element against Atrazine

Widespread use of the chlorotriazine herbicide, atrazine, has led to serious environmental and human health consequences. Current methods of detecting atrazine contamination are neither rapid nor cost-effective. In this work, atrazine-specific single-stranded DNA (ssDNA) molecular recognition elements (MRE) were isolated. We utilized a stringent Systematic Evolution of Ligands by Exponential Enrichment (SELEX) methodology that placed the greatest emphasis on what the MRE should not bind to. After twelve rounds of SELEX, an atrazine-specific MRE with high affinity was obtained. The equilibrium dissociation constant (Kd) of the ssDNA sequence is 0.62 ± 0.21 nM. It also has significant selectivity for atrazine over atrazine metabolites and other pesticides found in environmentally similar locations and concentrations. Furthermore, we have detected environmentally relevant atrazine concentrations in river water using this MRE. The strong affinity and selectivity of the selected atrazine-specific ssDNA validated the stringent SELEX methodology and identified a MRE that will be useful for rapid atrazine detection in environmental samples.
Controlled Direct and Mediated Effects: Definition, Identification and Bounds

Abstract. Results are given which provide bounds for controlled direct effects when nounmeasured confounding assumptions required for the identification of these effects do not hold. Previous results concerning bounds for controlled direct effects rely on monotonicity relationships between the treatment, mediator and the outcome themselves; the results presented in this article instead assume that monotonicity relationships hold between the unmeasured confounding variable or variables and the treatment, mediator and outcome. Whereas prior results give bounds that contain the null hypothesis of no direct effect, the results presented here will in many instances yield bounds that do not contain the null hypothesis of no direct effect. For contexts in which a set of variables intercepts all paths between a treatment and an outcome, it is possible to provide a definition for a controlled mediated effect. We discuss the identification of these controlled mediated effects; the bounds for controlled direct effects are applicable also to controlled mediated effects. An example is given to illustrate how the results in the article can be used to draw inferences about direct and mediated effects in the presence of unmeasured confounding variables.
Did It Happen? The Pragmatic Complexity of Veridicality Assessment

Natural language understanding depends heavily on assessing veridicality—whether events mentioned in a text are viewed as happening or not—but little consideration is given to this property in current relation and event extraction systems. Furthermore, the work that has been done has generally assumed that veridicality can be captured by lexical semantic properties whereas we show that context and world knowledge play a significant role in shaping veridicality. We extend the FactBank corpus, which contains semantically driven veridicality annotations, with pragmatically informed ones. Our annotations are more complex than the lexical assumption predicts but systematic enough to be included in computational work on textual understanding. They also indicate that veridicality judgments are not always categorical, and should therefore be modeled as distributions. We build a classifier to automatically assign event veridicality distributions based on our new annotations. The classifier relies not only on lexical features like hedges or negations, but also on structural features and approximations of world knowledge, thereby providing a nuanced picture of the diverse factors that shape veridicality. “All I know is what I read in the papers”—Will Rogers
A New Member of High Field Large Bore Superconducting Research Magnets Family

Over the last 5 years, Oxford Instruments has successfully developed a series of large bore, high field (hence high stored energy) magnet systems, using conventional NbTi and Nb3Sn low temperature superconductors (LTS). These systems are enabling many new customer applications which have not previously been possible with smaller usable volumes. The magnet systems built to date have cold bores ranging from 150mm to 250mm diameter with central field from 15T to 19T. As well as their use as “outsert” magnets for High Temperature Superconductor (HTS) magnet systems, applications also include Scanning Probe Microscopy (SPM) and dark matter research. In this paper, we will introduce a new member of our high energy magnet system family, with a central field of 12T and cold bore of 320mm incorporating a large field cancellation volume some distance above magnet centre line. We will discuss the challenges which have to be met to provide such magnets, including stress/strain control, quench energy management, coil force and mechanical support.
Cryptanalysis of Comparable Encryption in SIGMOD'16

Comparable Encryption proposed by Furukawa (ESORICS 2013, CANS 2014) is a variant of order-preserving encryption (OPE) and order-revealing encryption (ORE); we cannot compare a ciphertext of v and another ciphertext of v', but we can compare a ciphertext of v and a token of b and compare a token of $b$ and another token of b'. Comparable encryption allows us to implement range and point queries while keeping the order of v's as secret as possible. Recently, Karras, Malhotra, Bhatt, Nikitin, Antyukhov, and Idreos independently re-define comparable encryption and propose two schemes, a basic one and an "ambiguous" one, based on linear algebra~(SIGMOD 2016). The basic scheme is just comparable encryption. To hide the order revealed by tokens, they also proposed an ambiguous scheme where each ciphertext has two interpretations v and vdummy. In the context of an indexed database, this means that every encryption has two places in the database corresponding to the two interpretations, masking the correct placement in the database unless the dummy value is detectable. They assessed that their basic scheme (and ambiguous scheme upon the basic scheme) is secure against known-plaintext attacks; the adversary will require O(ℓ) plaintext-ciphertext pairs to recover secret key, where ℓ is a security parameter. This paper cryptanalyzes their comparable encryption schemes by using simple linear algebra. We show that a few tokens and a few plaintext-ciphertext pairs instead of O(ℓ) pairs allow us to mount several attacks efficiently. Our attacks are summarized as follows: Attacks against the basic scheme: -A ciphertext-only attack using two tokens orders the ciphertexts correctly. -A known-plaintext attack using two tokens and two plaintexts reveals exact value of v. Attacks against the ambiguous scheme: -A ciphertext-only attack using two tokens orders the ciphertexts with a constant probability. -A known-plaintext attack using three tokens and three plaintexts reveals exact value of v.
