Modeling eye movements in visual agnosia with a saliency map approach: Bottom–up guidance or top–down strategy?

Two recent papers (Foulsham, Barton, Kingstone, Dewhurst, & Underwood, 2009; Mannan, Kennard, & Husain, 2009) report that neuropsychological patients with a profound object recognition problem (visual agnosic subjects) show differences from healthy observers in the way their eye movements are controlled when looking at images. The interpretation of these papers is that eye movements can be

Design of Low-Order Controllers using Optimization Techniques

In many applications, especially in the process industry, low-level controllers are the workhorses of the automated production lines. The aim of this study has been to provide simple tuning procedures, either optimization-based methods or tuning rules, for design of low-order controllers. The first part of this thesis deals with PID tuning. Design methods or both SISO and MIMO PID controllers bas

Electron spectroscopy of rare-gas clusters irradiated by x-ray free-electron laser pulses from SACLA

We have measured electron energy spectra and asymmetry parameters of Ar clusters and Xe clusters illuminated by intense x-rays at 5 and 5.5 keV. A velocity map imaging spectrometer was developed for this purpose and employed at an x-ray free-electron laser facility, SACLA in Japan. The cluster size dependence and the peak fluence dependence of the electron spectra and asymmetry parameters are disc

The Political Foundations of Trust and Distrust: Reforms and Protests in France

This article argues that the high level of protest activity in France is, at least partly, the result of distrust between the government and the trade unions, and that such distrust is inevitable in a society where unions are sometimes strong enough to mobilise against the government but not confident in their own future strength. This trust problem can be overcome if governments are willing to ma

Communicational challenges in disaster risk management: Risk information sharing and stakeholder collaboration through risk and vulnerability assessments in Sweden

Many countries have established disaster risk management systems. These systems involve various parties and aim to maximize resources and use their diverse expertise to manage disaster risks. In such systems, sharing risk and vulnerability assessments (RVAs) between stakeholders is the most common way to communicate risk-related information. This study investigates communication challenges linked

Model-integrated estimation of normal tissue contamination for cancer SNP allelic copy number data.

SNP allelic copy number data provides intensity measurements for the two different alleles separately. We present a method that estimates the number of copies of each allele at each SNP position, using a continuous-index hidden Markov model. The method is especially suited for cancer data, since it includes the fraction of normal tissue contamination, often present when studying data from cancer t

How the polls can be both spot on and dead wrong: using choice blindness to shift political attitudes and voter intentions.

Political candidates often believe they must focus their campaign efforts on a small number of swing voters open for ideological change. Based on the wisdom of opinion polls, this might seem like a good idea. But do most voters really hold their political attitudes so firmly that they are unreceptive to persuasion? We tested this premise during the most recent general election in Sweden, in which

Tystnadens röst och själens musik

I religionernas värld har man alltid varit medveten om vilken betydelse ljud och tystnad har för vårt välbefinnande. Ibland framhävs tystnaden; i andra fall kan det röra sig om det monotona ljude av exempelvis en upprepad bön. Sådana övningar blir föremål för en psykologisk kommentar.

The Therapeutic Relationship and Adherence to Antipsychotic Medication in Schizophrenia

Objective: Previous research has shown that a better therapeutic relationship (TR) predicts more positive attitudes towards antipsychotic medication, but did not address whether it is also linked with actual adherence. This study investigated whether the TR is associated with adherence to antipsychotics in patients with schizophrenia. Methods: 134 clinicians and 507 of their patients with schizoph

2D Spectroscopy Study of Water-Soluble Chlorophyll-Binding Protein from Lepidium virginicum

Water-soluble chlorophyll-binding proteins (WSCPs) are interesting model systems for the study of pigment-pigment and pigment-protein interactions. While class IIa WSCP has been extensively studied by spectroscopic and theoretical methods, a comprehensive spectroscopic study of class IIb WSCP was lacking so far despite the fact that its structure was determined by X-ray crystallography. In this pa

Dimer-T(3) reconstruction of the Sm/Si(100)(2 x 3) surface studied by high-resolution photoelectron spectroscopy and density functional theory calculations

Silicon dimer-containing reconstructions on Si(100) can be induced by submonolayer amounts of rare earth (RE) metals. The tilt of dimer bonds in such reconstructions can be controlled by the coverage and electronic properties of RE adsorbates. In this study, we have utilized improved high-resolution photoelectron spectroscopy with the synchrotron radiation and density functional theory (DFT) calcu

Characterization of a double-sided silicon strip detector autoradiography system.

The most commonly used technology currently used for autoradiography is storage phosphor screens, which has many benefits such as a large field of view but lacks particle-counting detection of the time and energy of each detected radionuclide decay. A number of alternative designs, using either solid state or scintillator detectors, have been developed to address these issues. The aim of this stud

Underlying mechanisms behind adhesion of fermented milk to packaging surfaces

Fermented milk is commonly eaten during breakfast or as a snack between meals either in one-portion cups or from a bowl with a spoon. Approximately 5-10% of the fermented milk remains in the packages upon pouring, which during the last years, has received attention in public media as newspapers and television. This is a problem, not only from an economical point of view, but also from an ecologica

Luminescence properties of monoclinic Cu4I4(Piperidine)(4)

A new modification of Cu(4)I(4)Pip(4) has been synthesized under hydrothermal conditions. X-ray crystallography revealed that this compound crystallized in the monoclinic system and consists of a tetrahedral core with composition Cu4I4, in which each Cu atom is coordinated by a piperidine molecule via the N atom. In contrast to a previously reported modification of Cu(4)I(4)Pip(4), the present mod

Novel AAV-Based Rat Model of Forebrain Synucleinopathy Shows Extensive Pathologies and Progressive Loss of Cholinergic Interneurons.

Synucleinopathies, characterized by intracellular aggregation of α-synuclein protein, share a number of features in pathology and disease progression. However, the vulnerable cell population differs significantly between the disorders, despite being caused by the same protein. While the vulnerability of dopamine cells in the substantia nigra to α-synuclein over-expression, and its link to Parkinso

Participation in physical activity in relation to different life-change events

Regular physical activity is understood to be an essential prerequisite for human health for both psychological and physiological well-being. However, there are differences in participation in physical activity among different groups in society, and participation in physical activity can also change over a lifetime. The general aim of this thesis was to investigate how different life-change events

Constructing interorganizational collaboration The action researcher as boundary subject

This article aims to explore critically the role of an action research team in the social construction of interorganizational collaboration aimed at transgressing organizational and professional boundaries. We argue that the new relationships, actor conceptions and in some cases forms of work organization arising from the change process have been socially constructed through the discursive interve
