Work environment and changes in self‐rated health: a five year follow‐up study

A representative sample of 5001 Danish employees was followed for five years. The respondents were interviewed by telephone in 1990 and again in 1995. Social class, diseases, self-rated health (SRH), and a number of psychosocial and other work environment factors were assessed in 1990, and SRH was measured again in 1995. We analyzed predictors of changes in SRH from 1990 to 1995. After control for age, gender, and disease, the following factors predicted worsening of SRH among respondents with good SRH in 1990: repetitive work, high psychological demands, low social support, high job insecurity, and high ergonomic exposures. After further control for social class, the ORs for some of these factors were reduced, but they all remained significant. Only one of the work environment factors, ergonomic exposures, predicted improvements in SRH among those respondents who had poor SRH in 1990. Many studies have shown that SRH is a powerful independent predictor for total mortality. This is the first study showing that a number of work environment factors predict worsening of SRH over time.

A Task Taxonomy for Temporal Graph Visualisation

By extending and instantiating an existing formal task framework, we define a task taxonomy and task design space for temporal graph visualisation. We discuss the process involved in their generation, and describe how the design space can be `sliced and diced' into multiple overlapping task categories, requiring distinct visual techniques for their support. The approach addresses deficiencies in the task literature, offering domain independence, greater task coverage, and unambiguous task specification. The taxonomy and design space capture tasks for temporal graphs, and also static graphs, multivariate graphs, and graph comparison, and will be of value in the design and evaluation of temporal graph visualisation systems.
Issues in Arabic Orthography and Morphology Analysis

This paper discusses several issues in Arabic orthography that were encountered in the process of performing morphology analysis and POS tagging of 542,543 Arabic words in three newswire corpora at the LDC during 2002--2004, by means of the Buckwalter Arabic Morphological Analyzer. The most important issues involved variation in the orthography of Modern Standard Arabic that called for specific changes to the Analyzer algorithm, and also a more rigorous definition of typographic errors. Some orthographic anomalies had a direct impact on word tokenization, which in turn affected the morphology analysis and assignment of POS tags.
Financial Globalization, Financial Crises and Contagion

Two observations suggest that financial globalization played an important role in the recent financial crisis. First, more than half of the rise in net borrowing of the U.S. nonfinancial sectors since the mid 1980s has been financed by foreign lending. Second, the collapse of the U.S. housing and mortgage-backed-securities markets had worldwide effects on financial institutions and asset markets. Using an open-economy model where financial intermediaries play a central role, we show that financial integration leads to a sharp rise in net credit in the most financially developed country and leads to large asset price spillovers of country-specific shocks to bank capital. The impact of these shocks on asset prices are amplified by bank capital requirements based on mark-to-market.
Bridging the Gap between Enterprise Content Management and Creativity: A Research Framework

Enterprise content management (ECM) has emerged as a promising research area in the Information Systems (IS) discipline. According to recent works in the field, ECM may increase the consistency, availability, and traceability of content. We argue that one important aspect has dropped off the agenda-the role of creativity. While the above measures are, without any doubt, highly relevant in order to pursue important business imperatives, such as time and budget, organizations must also consider the creativity and innovativeness that employees can unfold in their work processes. In this conceptual paper, we thus advocate an approach to ECM research that not only considers traditional, rather control-oriented factors, but also the impact of ECM on an organization's creativity and vice versa. We propose a research framework for ECM and creativity that is grounded in diverse literatures relating to these two concepts.
Enron, Herding, and the Deterrent Effect of Disclosure of Improprieties

One objective of regulatory investigations of possible improprieties by publicly traded corporations and the imposition of sanctions if malfeasance is found is to deter other corporations from engaging in such behavior. Although the magnitude of the deterrent effect is an empirical issue, this paper provides an a priori analysis as to why the deterrent effect will be blunted in many cases, why its strength will not be uniform over time, and why, based in part on prospect theory, the deterrent effect will be weaker for ongoing questionable practices than for practices in their formative stages.

Atrophy patterns in histologic vs clinical groupings of frontotemporal lobar degeneration

Objective: Predictable patterns of atrophy are associated with the clinical subtypes of frontotemporal dementia (FTD): behavioral variant (bvFTD), semantic dementia (SEMD), and progressive nonfluent aphasia (PNFA). Some studies of pathologic subtypes have also suggested specific atrophy patterns; however, results are inconsistent. Our aim was to test the hypothesis that clinical, but not pathologic, classification (FTD with ubiquitin inclusions [FTD-U] and FTD with tau inclusions [FTD-T]) is associated with predictable patterns of regional atrophy. Methods: Magnetic resonance scans of nine FTD-U and six FTD-T patients (histologically confirmed) were compared with 25 controls using voxel-based morphometry (VBM). Analyses were conducted with the patient group classified according to histologic or clinical variant. Additionally, three Alzheimer pathology patients who had the syndrome of SEMD in life (FTD-A) were analyzed. Results: The VBM studies in clinical variants confirmed established patterns of atrophy (SEMD, rostral temporal; bvFTD, mesial frontal; PNFA, left insula). FTD-U and FTD-T VBM results were very similar, showing severe atrophy in the temporal poles, mesial frontal lobe, and insulae. A conjunction analysis confirmed this similarity. Subgroup analysis found that SEMD associated with either FTD-T or FTD-U was associated with similar rostral temporal atrophy; however, FTD-A had a qualitatively different pattern of left hippocampal atrophy. Conclusions: While there is predictable atrophy for clinical variants of frontotemporal dementia (FTD), histologic FTD variants show no noticeable differences. Reports of specific atrophy profiles are likely the result of idiosyncrasies in small groups. Semantic dementia associated with Alzheimer pathology, however, presented a distinct atrophy pattern.
Cortical Changes Across the Autism Lifespan

Although it is widely accepted that autism spectrum disorder (ASD) involves neuroanatomical abnormalities and atypical neurodevelopmental patterns, there is little consensus regarding the precise pattern of neuroanatomical differences or how these differences relate to autism symptomology. Furthermore, there is limited research related to neuroanatomical correlates of autism symptomology in individuals with ASD and the studies that do exist primarily include small samples. This study was the first to investigate gray matter (GM) changes throughout the ASD lifespan, using voxel‐based morphometry to determine whether significant differences exist in the GM volumes of a large sample of individuals with ASD compared to age‐ and IQ‐matched typical controls. We examined GM volume across the lifespan in 531 individuals diagnosed with ASD and 571 neurotypical controls, aged 7–64. We compared groups and correlated GM with age and autism severity in the ASD group. Findings suggest bilateral decreased GM volume for individuals with ASD in regions extending from the thalamus to the cerebellum, anterior medial temporal lobes, and orbitofrontal regions. Higher autism severity was associated with decreased GM volumes in prefrontal cortex, inferior parietal and temporal regions, and temporal poles. Similar relationships were found between GM volume and age. ASD diagnosis and severity were not associated with increased GM volumes in any region.

Beyond Levels and Growth: Estimating Teacher Value-Added and its Persistence

The levels and growth achievement functions make extreme and diametrically opposed assumptions about the rate at which teacher inputs persist. I first show that if these assumptions are incorrect, teacher value-added estimates can be significantly biased. I then develop a tractable, cumulative model of student achievement that allows for the joint estimation of unobserved teacher quality and its persistence. The model can accommodate varying persistence rates, student heterogeneity, and time-varying teacher attributes. I implement the proposed methodology using schooling data from North Carolina, and find that only a third of the contemporaneous teacher effect survives into the next grade.
Atrophic Gastritis, Helicobacter pylori, and Colorectal Cancer Risk: A Case‐Control Study

Background: Helicobacter pylori is a major risk factor for atrophic gastritis and gastric cancer. Various extragastric manifestations of H. pylori infection have also recently been suggested. However, the correlation between H. pylori and colorectal cancer (CRC) is controversial. The aim of this study was to examine the correlation between H. pylori, serum gastrin level, and atrophic gastritis with CRC.
Determination of ticarcillin levels in serum by high-pressure liquid chromatography

A high-pressure liquid chromatographic method for determining the concentrations of ticarcillin in serum was developed and compared, with 93 patient sera, to a standard agar well diffusion bioassay. For analysis, serum plus temocillin, the internal standard, were extracted with chloroform-n-amyl alcohol and back extracted into phosphate buffer. A reverse-phase C18 column and an ammonium acetate-methanol mobile phase were used with detection at 242 nm. Reproducibility studies yielded coefficients of variation ranging from 2.4 to 4.7% for low, mid, and high controls. Although cefoxitin, cephalothin, and cefuroxime exhibited retention similar to that of ticarcillin, a wide range of commonly administered antibiotics and other drugs did not interfere. The high-pressure liquid chromatographic assay is an accurate, reproducible method for determining the concentration of ticarcillin in serum during multiple antibiotic therapy or when rapid results are required.
The antiplasmodium effects of a traditional South American remedy: Zanthoxylum chiloperone var. angustifolium against chloroquine resistant and chloroquine sensitive strains of Plasmodium falciparum

Zanthoxylum chiloperone var. angustifolium Engl. , Rutaceae, is used in traditional medicine to treat fungal and protozoal infections in the central area of South America. Considering the increasing resistance of Plasmodium falciparum in malarial ridden areas, we explored the anti-plasmodial effects of three compounds isolated from Z. chiloperone. The pyranocoumarin transavicennol and the canthinone alkaloids, canthin-6-one and 5-methoxycanthin-6-one, were found to have IC50 on chloroquine/mefloquine resistant and sensitive strains of P. falciparum of 0.5-2.7, 2.0-5.3 and 5.1-10.4 ƒEg/mL, respectively. Moreover, the formation of heme adducts by these compounds is described by a novel alternative method based on MS-CID methods. The alkylamide sanshool was also identified, for first time in this plant, in the dichloromethanic and ethanolic extracts and the extracts were found to be notably non-toxic and displayed good anti-plasmodial effects.
High melanosome engulfing activity of cutaneous fibroblasts in macular amyloidosis: an electron microscopic study

Six patients with macular amyloidosis were investigated by electron microscopy and various morphological changes in fibroblasts were identified. Many cells, which seemed to be macrophages by light microscopy, proved to be fibroblasts. The digesting action of fibroblasts was well developed and many melanosomes were taken into the cells making the cells resemble melanophages. The fibroblasts extended long, thin and branched cytoplasmic processes to surround the amyloid mass, and the cells selectively extended these into the narrow spaces between collagen and amyloid. The fibroblast showed highly developed endocytotic activity and probable ingcstion of amyloid by pinocytosis or phagocytosis. The developed rough cndoplasmic reticulum contained much protein and was active in secretion.
People-centric mobile sensing with a pragmatic twist: from behavioral data points to active user involvement

Mobile phones have recently been used to collect largescale continuous data about human behavior. This people centric sensing paradigm is useful not only from a scientific point of view: Contextual user data has pragmatic value, too. Individuals whose data is collected in such long-term people centric sensing projects can be engaged in user centric design activities aiming to generate data driven services that benefit the end user. This paper demonstrates the value of such user centric approach. In a two-stage approach, we analyse mobile phone data to extract mobile phone usage c ategories. We then go on to interview the participants concerning their perceptions toward context-aware services. The two sta ges, combined as we present here, offer a clear value in ter ms of provi ding complementary insights, both to researchers and users, about the feasibility of and the expectations about personalized mobile services.
Animated agent immediacy and news services with handheld computers

The present study considers the design and implementation of immediacy behaviors for an animated agent and the influence of such an agent on viewers. Immediacy, a widely studied construct in human communication research, is defined as the verbal and nonverbal communication behaviors that enhance physical and psychological closeness between people. In this study, the use of animated agent immediacy with new technology, a handheld computer, was studied as a form of affective computing. The purpose of the study was first to find out whether users perceive the communication behaviors of the agent that were intended to enhance immediacy, second, what effects animated agent immediacy has on evaluations of a news service, and third whether affective learning or recall of news content is related to agent immediacy. The results revealed that communication behaviors that enhance immediacy were perceived by the users. Those behaviors were also related to their perception of immediacy. However, the animated agent immediacy did not have a significant effect on evaluation of the news service. Additionally, agent immediacy had no effect on affective or cognitive learning from the news. The results show that it is possible to construct immediacy behaviors for the animated agents, but in this context the influences differed from those reported in human‐to‐human communication. The possibilities for and consequences of agent immediacy are also discussed, as are the reasons why the effects of immediacy on evaluations and learning were not found in the present study.
Fabrication of test structures to monitor stress in SU-8 films used for MEMS applications

SU-8, an epoxy based negative photoresist, is widely used in the manufacture of micromechanical systems but can exhibit significant levels of stress build-up during processing. This paper describes micromechanical test structures that provide the opportunity to spatially characterise stress the in SU-8 at different stages of the process. The structures are fabricated in a thick layer of SU-8 and are subsequently released from the underlying substrate using a dry chemical vapour etch process. The initial results indicate that there is significant tensile stress in the SU-8, and that this demonstrates a radial variation along with a dependence on the process conditions.
Every monotone graph property has a sharp threshold

In their seminal work which initiated random graph theory Erdos and Renyi discovered that many graph properties have sharp thresholds as the number of vertices tends to infinity. We prove a conjecture of Linial that every monotone graph property has a sharp threshold. This follows from the following theorem. Let Vn(p) = {0, 1}n denote the Hamming space endowed with the probability measure μp defined by μp( 1, 2, . . . , n) = pk · (1 − p)n−k, where k = 1 + 2 + · · · + n. Let A be a monotone subset of Vn. We say that A is symmetric if there is a transitive permutation group Γ on {1, 2, . , n} such that A is invariant under Γ. Theorem. For every symmetric monotone A, if μp(A) > then μq(A) > 1− for q = p+ c1 log(1/2 )/ logn. (c1 is an absolute constant.)
Skin Autofluorescence as a Measure of Advanced Glycation End Products Deposition Predicts 5-Year Amputation in Patients With Peripheral Artery Disease

Objective—Patients with peripheral artery disease are at risk for critical limb ischemia and amputation. Accumulation of advanced glycation end products is increased and predictive for coronary and cerebrovascular events in several high cardiovascular risk groups. We hypothesized that accumulation of tissue advanced glycation end products, measured by skin autofluorescence (SAF), predicts amputation in patients with peripheral artery disease. Approach and Results—Between October 2007 and June 2008, 252 patients with peripheral artery disease were included at the outpatient clinic. During a 5-year follow-up, 22 (9%) had an amputation because of critical limb ischemia. Competing risks regression analysis showed a subproportional hazard ratio of 3.05 (95% confidence interval [CI], 1.87–4.96); P<0.0001 for amputation per unit incease of SAF. After correction for diabetes mellitus and Fontaine stage, subproportional hazard ratio was 2.72 (95% CI, 1.38–5.39); P=0.004. In patients with Fontaine stage I and II only (n=215), SAF was the only predictor for amputation, subproportional hazard ratio 4.05 (95% CI, 2.09–7.83); P<0.0001. Fontaine stage multiplied by SAF resulted in a significant increase of the area under the curve for prediction of amputation when compared with Fontaine stage only: area under the curve increased from 0.74 (95% CI, 0.63–0.86) to 0.83 (95% CI, 0.74–0.92); P=0.003. Conclusions—Skin autofluorescence, as a measure of tissue advanced glycation end products deposition, predicts amputation in patients with peripheral artery disease during a 5-year follow-up, independent from the presence of diabetes mellitus and Fontaine stage. Even at lower Fontaine stage (I or II), SAF is a strong predictor of amputation. The multiplication of Fontaine stage by SAF results in a good prediction model of amputation.
Risks and Controls in Internet-Enabled Reverse Auctions: Perspectives from Buyers and Suppliers

Abstract Internet-enabled reverse auctions (RAs) are touted as a means of making the procurement process more effective and efficient, but as is often the case with information technology (IT), there can be risks that managers need to be aware of and mitigate in order to realize the benefits. Using the Delphi methodology followed by semistructured interviews, we identify buyer and supplier perspectives on risk factors associated with RAs and the controls that can address key risk factors. We find that the risk factors map to (1) auction process governance, (2) organizational contingency, (3) buyer–supplier relationship, and (4) agency and transaction cost. Drawing on the findings, we advance an RA risk-control integrative model and formulate corresponding propositions (1) comparing buyers’ and suppliers’ perspectives on risks associated with RA use and (2) identifying controls to mitigate the risks. Our research contributes to theory by (1) surfacing that RAs introduce novel risks and that buyers and suppliers can have either similar or remarkably different views regarding particular risks, (2) showing how both buyers and suppliers can create information asymmetry and act opportunistically, and (3) uncovering the role of input controls, a type of control that has not received much attention in the literature on controls for IT initiatives, as an effective means of addressing most of the key risk factors. For practitioners, our study provides guidance about a wide range of risk factors that both parties could face when using RAs, the adverse consequences of these risk factors, and the controls that can be established to mitigate the key risk factors.
Competencies for successful self-regulated learning in higher education: structural model and indications drawn from expert interviews

A global characteristic of higher education is the opportunity and necessity for students to self-regulate their learning. In contrast to considerable research focusing on self-regulated learning (SRL) from a behavioural perspective, little is known concerning the underlying competencies which enable students to succeed in SRL. A structural model is proposed that differentiates SRL competencies in terms of descriptive, procedural, and conditional knowledge regarding different types of self-regulation strategies in different phases of the learning process. Indications drawn from semi-structured interviews with N = 108 experts (39 lecturers and 69 as excellent nominated students) from 4 fields of study are in line with core assumptions of the proposed model. Moreover, the results provide a basis to ensure the content validity of assessments of students’ SRL competencies and from which to derive standards to judge these competencies.
Dental Caries and Growth in School-Age Children

BACKGROUND AND OBJECTIVE: Dental caries in young children is commonly untreated and represents a public health problem. Dental caries in children is reported to affect their anthropometric outcomes, but the evidence is conflicting. Some studies found no association, whereas others found that caries was associated with underweight or overweight. The objective was to assess the relationship between dental caries status and height and weight in 6- to 8-year-old Saudi children with high caries prevalence. METHODS: This study was a cross-sectional survey in schoolchildren aged 6 to 8 years attending military primary schools in Jeddah, Saudi Arabia. Caries status was assessed by using the dmft (decayed, missing, filled, teeth [primary teeth]) index. Height and weight were assessed by using z scores of height-for-age (HAZ), weight-for-age (WAZ), and BMI-for-age (BAZ) calculated by World Health Organization standardized procedures. Relationships between caries and HAZ, WAZ, and BAZ were assessed by using regression models. RESULTS: A total of 417 of the 436 eligible schoolchildren with complete data were included, with a response rate of 95.6%. Their mean dmft index was 5.7 ± 4.2. There was an inverse linear relationship between caries status and children’s HAZ, WAZ, and BAZ and significantly lower anthropometric outcomes for children at each consecutive group with higher levels of caries. The associations remained significant after adjusting for dental, social, and demographic variables. CONCLUSIONS: The inverse linear association between dental caries and all anthropometric outcomes suggests that higher levels of untreated caries are associated with poorer growth in Saudi schoolchildren.
