Predictors of change in anxiety symptoms of older persons: results from the Longitudinal Aging Study Amsterdam

Background. Data on the course of anxiety in late life are scarce. The present study sets out to investigate the course of anxiety, as measured by the HADS-A (Zigmond & Snaith, 1983) in community dwelling older persons, and to evaluate predictive factors for change over 3 years in anxiety symptoms following the vulnerability/stress model. Method. Based on the first anxiety assessment, two cohorts were formed: subjects with and subjects without anxiety symptoms. In the non-anxious cohort (N = 1602) we studied risk factors for the development of anxiety symptoms; in the anxious cohort (N = 563) the same factors were evaluated on their predictive value for restitution of symptoms. Risk factors included vulnerability factors (demographics, health status, personality characteristics and social resources) and stressors (life events occurring in between both anxiety assessments). Logistic regression models estimated the effects of vulnerability factors, stress and their interaction on the likelihood of becoming anxious and chronicity of anxiety symptoms. Results. It was indicated that the best predictors for becoming anxious were being female, high neuroticism, hearing/eyesight problems and life-events. Female sex and neuroticism also increased the likelihood of chronicity of anxiety symptoms in older adults, but life events were not related to chronicity. The main stressful event in late life associated with anxiety was death of one's partner. Vulnerability factors and stress added on to each other rather than their interaction being associated with development or chronicity of anxiety. Conclusion. The vulnerability/stress model offers a useful framework for organizing risk factors for development and chronicity of anxiety symptoms in older persons, but no support was attained for the hypothesis that vulnerability and stress amplify each others effects. Finally, the results indicate to whom preventive efforts should be directed: persons high in neuroticism, women, and those who experience distressing life events.
Evaluating Labour Market Interventions

The high growth rates experienced in Ireland over the last 10 years has resulted in a tightening of the labour market which is reflected in the number of unfilled vacancies reported by firms. At the same time wage inequality has increased leading to greater demands being placed on the government to tackle social exclusion. In response to these issues, recent governments have proposed a range of policies involving direct intervention in the labour market. Effective implementation of these policies requires careful monitoring and evaluation of their effects. In this paper I examine the procedures currently available for evaluating labour market interventions. The results of recent evaluations of minimum wages laws, reform of the benefit system and changes in working-time conditions are used to illustrate the methodologies involved. I also describe the data requirements of these methodologies and examine the currently available Irish labour market data in this light.
A new way to deal with Izergin-Korepin determinant at root of unity

I consider the partition function of the inhomogeneous 6-vertex model defined on the $n$ by $n$ square lattice. This function depends on 2n spectral parameters $x_i$ and $y_i$ attached to the horizontal and vertical lines respectively. In the case of domain wall boundary conditions it is given by Izergin-Korepin determinant. For $q$ being a root of unity the partition function satisfies to a special linear functional equation. This equation is particularly good when the crossing parameter $\eta=2\pi/3$. In this case it can be used for solving some of the problems related to the enumeration of alternating sign matrices. In particular, it is possible to reproduce the refined ASM distribution discovered by Mills, Robbins and Rumsey and proved by Zeilberger. Further, it is well known that the partition function is symmetric in the $\{x\}$ and as well in the $\{y\}$ variables. I have found that in the case of $\eta=2\pi/3$, the partition function is symmetric in the union $\{x\} \cup \{y\}$! This nice symmetry is used to find some relations between the numbers of such alternating sign matrices of order $n$ whose two '1' are located in fixed positions on the boundary of the matrices. Finally I derive the equation giving `top-bottom double refined' ASM distribution.
Controllability and invariance of monotone systems for robust ventilation automation in buildings

The problem considered is the temperature control in a building equipped with UnderFloor Air Distribution (UFAD). Its 0-D model is derived from the energy and mass conservation in each room, and also presents discrete components to describe the disturbances from heat sources and doors opening. Using the monotonicity of this model, we can characterize two concepts of robust control, the Robust Controllability and the Robust Controlled Invariance introduced in this paper, and determine their limits for control design objectives. The validity of these results is then illustrated in a simulation of a two-room example.
Book Club Groups to Aid Relational Connection and Trust among Addicted Trauma Survivors

ABSTRACT This is a secondary analysis of qualitative data from a literacy study, which examines Book Clubs as a creative approach to engage female addicted trauma survivors in developing psychologically safe, trusting therapeutic relationships. This approach is respectful of the participants’ experiences of relational trauma and diverse cultural contexts, in part because book clubs are ‘normal’ experiences in which the client is better able to have control over the level of vulnerability she engages in within the therapeutic milieu. Themes indicating increasing levels of vulnerability and psychological safety include use of book club discussions to identify with text, plot, or characters; to discuss escape coping and aggressive coping; and to discuss self as a victim and as a survivor.
‘AnthropOcean’: Oceanic perspectives and cephalopodic imaginaries moving beyond land-centric ecologies

We sought contributions from the widest possible spectrum, asking the authors to reflect upon the notion of ‘AnthropOcean’: theory, fiction, journal, ethological accounts, or ethnographic material from time spent at sea, testimony by those who have gained experience from the ocean, encounters with ocean inhabitants (no species preferred), etc. The aim is to build imagination and sensitivity upon these contributions in order to invent new narrative forms coherent with our contemporary experiences of an animated world. We would like to suggest that oceanic sensitive-anthropology can provide precious sense-ideas in order to think, feel and imagine the contemporary ecological crisis. Considering our present as anything but an ‘end of the world’, and more as a profound transformative process, how can ocean-sense-ideas bring useful intuitions? How can ocean inhabitants, ecosystems and dynamics, teach us a lesson in imagination? Can we dream other dreams than that of industrial exploitation?
Extension of the method of auxiliary mapping for three-dimensional elliptic boundary value problems

SUMMARY In this paper, we extend the method of auxiliary mapping (MAM), introduced by Babuska and Oh, to three dimensions so that the extended MAM (3-D MAM) can eectively handle three-dimensional elliptic problems containing the singularities caused by the non-smooth domains. There are three type of singularities caused by non-smoothness of domains in R 3 : the vertex, the edge, and the vertex{edge combined singularities. To deal with the singularities of these types, we present three auxiliary mappings and formulas for the transformed bilinear forms and the transformed linear functionals by these auxiliary mappings. Then we present 3-D MAM and constructions of the blending-type elemental mappings for elements containing singularities. Numerical experiments that show the eectiveness of 3-D MAM are provided.

S ep 2 00 0 Destabilization and Localization of Traveling Waves by an Advected Field

We study a model of small-amplitude traveling waves arising in a supercritical Hopfbifurcation, that are coupled to a slowly varying, real field. The field is advected by the waves and, in turn, affects their stability via a coupling to the growth rate. In the absence of dispersion we identify two distinct shortwave instabilities. One instability induces a phase slip of the waves and a corresponding reduction of the winding number, while the other leads to a modulated wave structure. The bifurcation to modulated waves can be either forward or backward, in the latter case permitting the existence of localized, traveling pulses which are bistable with the basic, conductive state.
A Chlamydomonas outer arm dynein mutant missing the alpha heavy chain

A novel Chlamydomonas flagellar mutant (oda-11) missing the alpha heavy chain of outer arm dynein but retaining the beta and gamma heavy chains was isolated. Restriction fragment length polymorphism analysis with an alpha heavy chain locus genomic probe indicated that the oda-11 mutation was genetically linked with the structural gene of the alpha heavy chain. In cross-section electron micrographs, the oda-11 axoneme lacked the outermost appendage of the outer arm, indicating that the alpha heavy chain should be located in this region in the wild-type outer arm. This mutant swam at 119 microns/s at 25 degrees C, i.e., at an intermediate speed between those of wild type (194 microns/s) and of oda-1 (62 microns/s), a mutant missing the entire outer dynein arm. The flagellar beat frequency (approximately 50 Hz) was also between those of wild type (approximately 60 Hz) and oda-1 (approximately 26 Hz). These results indicate that the outer dynein arm of Chlamydomonas can be assembled without the alpha heavy chain, and that the outer arm missing the alpha heavy chain retains partial function.
European Conference on Information Systems ( ECIS ) 5-7-2012 EXPLORING THE RELATION BETWEEN FIRM OWNERSHIP AND IT CAPABILITY

As IT spending continuously increased throughout the last years, it nowadays accounts for a significant amount of total corporate spending. Simultaneously, academic research validated the strategic importance and performance benefits derived from a superior IT capability – the ability to successfully deploy organizational IT skills and resources. Furthermore, shareholders pursuing longterm oriented goals are interested in consistent investments to develop organizational capabilities, such as IT capability. Consequentially, the question arises how a firm’s ownership structure is related to its IT capability. This research question is addressed by analyzing secondary data on publicly listed U.S. companies of the last ten years. The results provide support for the hypothesized relation throughout the investigated period and withstand several control and robustness tests. This study contributes to the ongoing research on IT capability by showing that certain types of shareholders promote the development and deployment of IT capability which in turn influences strategic topics. Findings further confirm that decisions on IT investments characterized by long-term benefits must be backed by owners with a corresponding long-term investment horizon.
Extraction of scientific semantic networks from science textbooks and comparison with science teachers’ spoken language by text network analysis

ABSTRACT Just as language reflects one’s thoughts, the text of science textbooks reflects the structure of scientific knowledge and thought. Therefore, students’ learning of scientific language leads to their acquisition of the structure of scientific knowledge and thought. The purposes of this study were to extract scientific semantic network from science textbooks as the ideal model of using scientific language, and to examine how well science teachers are implementing scientific semantic networks in science classes by comparing and analysing their spoken language. Through a recursive method, science textbooks were searched for keywords and their relationships, and consequently a scientific semantic network was presented. As a result of the comparison with science teachers’ spoken language, it was found that the teachers were not able to implement the scientific semantic network exactly and efficiently in class, and the focus of the contents of their instruction was also different from the textbook. Science textbook was focused on qualitative aspects of the concept such as meaning, element, characteristic etc, on the other hand science teachers’ language was focused on quantitative aspect of the concept such as calculation, graph etc.
A methodology to assess the impact of source code flaws in changeability, and its application to clones

Some characteristics of source code are perceived as harmful because they evidence that design principles were not applied in certain parts of the application. This work proposes a methodology that assesses the effect of so called source code flaws in changeability. Our methodology is based on measures and indicators of the effort of changing methods. The measures are calculated with information automatically extracted from source code repositories, being therefore objective. We analyze the effect of clones in methods using the methodology, and we show its potential for better understanding the effect of low level structure in changeability.
Reanalysis of the DEMS Nested Case-Control Study of Lung Cancer and Diesel Exhaust: Suitability for Quantitative Risk Assessment

The International Agency for Research on Cancer (IARC) in 2012 upgraded its hazard characterization of diesel engine exhaust (DEE) to “carcinogenic to humans. ” The Diesel Exhaust in Miners Study (DEMS) cohort and nested case‐control studies of lung cancer mortality in eight U.S. nonmetal mines were influential in IARC's determination. We conducted a reanalysis of the DEMS case‐control data to evaluate its suitability for quantitative risk assessment (QRA). Our reanalysis used conditional logistic regression and adjusted for cigarette smoking in a manner similar to the original DEMS analysis. However, we included additional estimates of DEE exposure and adjustment for radon exposure. In addition to applying three DEE exposure estimates developed by DEMS, we applied six alternative estimates. Without adjusting for radon, our results were similar to those in the original DEMS analysis: all but one of the nine DEE exposure estimates showed evidence of an association between DEE exposure and lung cancer mortality, with trend slopes differing only by about a factor of two. When exposure to radon was adjusted, the evidence for a DEE effect was greatly diminished, but was still present in some analyses that utilized the three original DEMS DEE exposure estimates. A DEE effect was not observed when the six alternative DEE exposure estimates were utilized and radon was adjusted. No consistent evidence of a DEE effect was found among miners who worked only underground. This article highlights some issues that should be addressed in any use of the DEMS data in developing a QRA for DEE.
Organization and evolution of D region class I genes in the mouse major histocompatibility complex

Chromosome walking has been used to study the organization of the class I genes in the D and Qa regions of the MHC of the BALB/c mouse and in the D region of the AKR mouse. Five and eight class I genes are found in the D and Qa regions of the BALB/c mouse, respectively, while the AKR mouse contains only a single class I D region gene that has been identified by transfection as the Dk gene. Restriction map homologies and crosshybridization experiments suggest that the multiple class I genes in the D region of the BALB/c mouse have been generated by unequal crossing-over involving class I genes from the Qa region. The expanded D region of BALB/c and other H-2d haplotype mouse strains appears to be metastable, since evidence for gene contraction in the Dd region has been found in two mutant strains. Thus the D region and also the Qa region class I genes are in a dynamic state, evolving by gene expansion and contraction.
The Effects of Restricted Peripheral Field-of-View on Spatial Learning while Navigating

Recent work with simulated reductions in visual acuity and contrast sensitivity has found decrements in survey spatial learning as well as increased attentional demands when navigating, compared to performance with normal vision. Given these findings, and previous work showing that peripheral field loss has been associated with impaired mobility and spatial memory for room-sized spaces, we investigated the role of peripheral vision during navigation using a large-scale spatial learning paradigm. First, we aimed to establish the magnitude of spatial memory errors at different levels of field restriction. Second, we tested the hypothesis that navigation under these different levels of restriction would use additional attentional resources. Normally sighted participants walked on novel real-world paths wearing goggles that restricted the field-of-view (FOV) to severe (15°, 10°, 4°, or 0°) or mild angles (60°) and then pointed to remembered target locations using a verbal reporting measure. They completed a concurrent auditory reaction time task throughout each path to measure cognitive load. Only the most severe restrictions (4° and blindfolded) showed impairment in pointing error compared to the mild restriction (within-subjects). The 10° and 4° conditions also showed an increase in reaction time on the secondary attention task, suggesting that navigating with these extreme peripheral field restrictions demands the use of limited cognitive resources. This comparison of different levels of field restriction suggests that although peripheral field loss requires the actor to use more attentional resources while navigating starting at a less extreme level (10°), spatial memory is not negatively affected until the restriction is very severe (4°). These results have implications for understanding of the mechanisms underlying spatial learning during navigation and the approaches that may be taken to develop assistance for navigation with visual impairment.

Capacity Bounds and Low Complexity Transceiver Design for Double-Scattering MIMO Multiple Access Channels

We investigate the sum capacity and present low complexity transceiver designs for the multiple-input multiple-output (MIMO) multiple access channel (MAC) under a general class of fading, known as double-scattering. We assume that the receiver has perfect channel state information (CSI), while each transmitter only has access to its own statistical CSI. We show that the optimum transmit directions for each user coincide with the eigenvectors of the user's own transmit spatial correlation matrix. We also derive new closed-form upper bounds on the sum capacity of the MIMO MAC under double-scattering, which are subsequently employed to obtain low complexity power allocation policies which are easy to compute, and require each user to know only their own channel statistics. Then, we establish beamforming optimality conditions for all users. Finally, we consider the case as the number of users becomes large, in which case we demonstrate that beamforming is asymptotically optimal.
Bayesian P-Splines

P-splines are an attractive approach for modeling nonlinear smooth effects of covariates within the additive and varying coefficient models framework. In this article, we first develop a Bayesian version for P-splines and generalize in a second step the approach in various ways. First, the assumption of constant smoothing parameters can be replaced by allowing the smoothing parameters to be locally adaptive. This is particularly useful in situations with changing curvature of the underlying smooth function or with highly oscillating functions. In a second extension, one-dimensional P-splines are generalized to two-dimensional surface fitting for modeling interactions between metrical covariates. In a last step, the approach is extended to situations with spatially correlated responses allowing the estimation of geoadditive models. Inference is fully Bayesian and uses recent MCMC techniques for drawing random samples from the posterior. In a couple of simulation studies the performance of Bayesian P-splines is studied and compared to other approaches in the literature. We illustrate the approach by two complex application on rents for flats in Munich and on human brain mapping.
Prevalence and MDCT characteristics of asymptomatic Bochdalek hernia in adult population.

PURPOSE To determine the frequency of asymptomatic incidental Bochdalek hernias in adults, using multidetector computed tomography (MDCT), and to ascertain any possible relationship between Bochdalek hernia and age, gender, or body mass index (BMI). MATERIALS AND METHODS Seven hundred and forty-eight abdominal, and 602 chest MDCT scans, which had been performed for a variety of reasons on 1350 adults, were investigated retrospectively. Location and size of Bochdalek hernias seen on these scans were correlated with age, gender, and BMI. On the basis of BMI, patients with Bochdalek hernia were classified as group A (BMI < 25) and group B (BMI > or =25). RESULTS A total of 171 Bochdalek hernias were identified in 142 of 1350 patients, ranging in age from 25 to 90 years (median age, 57.2), representing a prevalence of 10.5%. Sixty leftsided unilateral Bochdalek hernias (42.2%), 53 (37.4%) rightsided unilateral Bochdalek hernias, and 29 (20.4%) bilateral Bochdalek hernias were detected. Forty-five (31.6%) were categorized as small, 82 (57.8%) were medium-sized, and 15 (10.5%) were large. BMI was < 25 in 62 patients (43.7%), and > or =25 in 80 patients (56.3%). Fourteen patients (9.9%) were young adults, while 86 (60.6%) were middle aged, and 42 (29.6%) were elderly. No statistically significant relationship was found between dimensions or hernia locations and age, gender, or BMI of patients with Bochdalek hernia. CONCLUSION In view of the high prevalence of Bochdalek hernia in our study (10.5%), the multiplanar and reconstruction features of MDCT seem to facilitate the diagnosis of asymptomatic incidental Bochdalek hernia. No relationship was found between asymptomatic incidental Bochdalek hernia and age, gender, or BMI in adults.
