Spatial Epidemiology of Escherichia coli O157:H7 in Dairy Cattle in Relation to Night Roosts Of Sturnus vulgaris (European Starling) in Ohio, USA (2007–2009)

The goal of our study was to use spatial scan statics to determine whether the night roosts of European starlings (Sturnus vulgaris) act as point sources for the dissemination of Escherichia coli O157:H7 among dairy farms. From 2007 to 2009, we collected bovine faecal samples (n = 9000) and starling gastrointestinal contents (n = 430) from 150 dairy farms in northeastern Ohio, USA. Isolates of E. coli O157:H7 recovered from these samples were subtyped using multilocus variable‐number tandem repeat analysis (MLVA). Generated MLVA types were used to construct a dendrogram based on a categorical multistate coefficient and unweighted pair‐group method with arithmetic mean (UPGMA). Using a focused spatial scan statistic, we identified statistically significant spatial clusters among dairy farms surrounding starling night roosts, with an increased prevalence of E. coli O157:H7‐positive bovine faecal pats, increased diversity of distinguishable MLVA types and a greater number of isolates with MLVA types from bovine‐starling clades versus bovine‐only clades. Thus, our findings are compatible with the hypothesis that starlings have a role in the dissemination of E. coli O157:H7 among dairy farms, and further research into starling management is warranted.
The Rorschach: Toward a nomothetically based, idiographically applicable configurational model.

The authors argue that the Rorschach can and should be used best with a nomothetic foundation that adds an idiographic approach depending on the goal of the assessment. The research supporting this position is reviewed as are conceptual models that are advantageous to this conceptual position. The authors posit that method variance has a powerful impact on the measurement process. Each method is of value in some areas and of limited relevance in others. Self-report measures are most likely to be useful when interest is focused on consciously available and behavioral dimensions of functioning. Depth-oriented, indirect measures such as the Rorschach are most likely to be useful when interest is focused on unconscious, longitudinal, and structural dimensions of functioning. However, to have a full picture of human beings, heteromethod assessment is necessary to capture the full range of functioning and to implement the analytic model of assessment.
Cerebellar Control of Saccades in Health and Disease

textabstractVision is one of the senses that are used for gathering information about the surrounding environment. Patterns of light reflecting from the environment enter the eye and are projected onto the retina. The retina harbors photoreceptors, which transform the patterns of light into the electrical activity that neurons use to convey visual information. This information enables humans to observe and interact with the environment. To gather detailed visual information about the properties of an object of interest, it must be projected on the fovea. The fovea is the part of the retina that has the highest density of photoreceptors and therefore provides the highest visual acuity. The projection of (moving) objects can be kept on the fovea using smooth pursuit eye movements, and new objects can be targeted by using saccadic eye movements. Eye movements can be recorded and quantified with relative ease. Current technology enables us not only to record eye movements in healthy adults in a laboratory setting, but also in more challenging subjects such as children or patients, or to record concurrently with functional imaging in a MR-scanner. Eye movements can be studied at multiple levels, ranging from the quantification of reflexive behavior to the inference of cognitive strategies involved in voluntary eye movement control. With properly designed studies it is possible to assign a functional role to the different stages in the visuo-oculomotor pathways. These characteristics propelled a large number of electrophysiological and behavioral studies on eye movements in non-human primates and humans. Functional imaging studies during the last twenty years have opened new ways for further investigations of the oculomotor system. The accumulating knowledge from these electrophysiological, behavioral and the more recent imaging studies has led to a detailed, but not complete, understanding of the neuronal pathways that subserve the oculomotor system. This also led to the appreciation that eye movements exhibit specific abnormalities when a confined part of the nervous system that is involved in these eye movements is affected by disease or trauma. Therefore, eye movement abnormalities have a clear clinical value and can contribute to the diagnostic process in a clinical setting. This thesis focuses on the neuronal pathways and clinical use of saccadic and smooth pursuit eye movements.
Self-advocacy for People with Learning Difficulties: Does it have a future?

ABSTRACT Within such a short-time self-advocacy has become not only fashionable amongst organisations of people with learning difficulties, but also with service providers and non-disabled individuals who have worked in traditional services. The concerns are that self-advocacy has become a process of consulting with users about what they want from services which are usually designed and delivered by non-disabled people. This had led to people recognising and accepting choices that are on offer by non-disabled people. As a consequence an artificial boundary around self-advocacy has been created which has led to people only speaking up about what society is prepared to make available (usually in form of segregated and supervised services) rather than challenging the (lack of) power that people with learning difficulties have in their lives. For people with learning difficulties to gain real change in their personal lives self-advocacy needs to be developed to ensure they not only have the communication skil.
Fossilized glycolipids reveal past oceanic N2 fixation by heterocystous cyanobacteria

N2-fixing cyanobacteria play an essential role in sustaining primary productivity in contemporary oceans and freshwater systems. However, the significance of N2-fixing cyanobacteria in past nitrogen cycling is difficult to establish as their preservation potential is relatively poor and specific biological markers are presently lacking. Heterocystous N2-fixing cyanobacteria synthesize unique long-chain glycolipids in the cell envelope covering the heterocyst cell to protect the oxygen-sensitive nitrogenase enzyme. We found that these heterocyst glycolipids are remarkably well preserved in (ancient) lacustrine and marine sediments, unambiguously indicating the (past) presence of N2-fixing heterocystous cyanobacteria. Analysis of Pleistocene sediments of the eastern Mediterranean Sea showed that heterocystous cyanobacteria, likely as epiphytes in symbiosis with planktonic diatoms, were particularly abundant during deposition of sapropels. Eocene Arctic Ocean sediments deposited at a time of large Azolla blooms contained glycolipids typical for heterocystous cyanobacteria presently living in symbiosis with the freshwater fern Azolla, indicating that this symbiosis already existed in that time. Our study thus suggests that heterocystous cyanobacteria played a major role in adding “new” fixed nitrogen to surface waters in past stratified oceans.
On the absence of the RIP in real-world applications of compressed sensing and the RIP in levels

The purpose of this paper is twofold. The first is to point out that the Restricted Isometry Property (RIP) does not hold in many applications where compressed sensing is successfully used. This includes fields like Magnetic Resonance Imaging (MRI), Computerized Tomography, Electron Microscopy, Radio Interferometry and Fluorescence Microscopy. We demonstrate that for natural compressed sensing matrices involving a level based reconstruction basis (e.g. wavelets), the number of measurements required to recover all $s$-sparse signals for reasonable $s$ is excessive. In particular, uniform recovery of all $s$-sparse signals is quite unrealistic. This realisation shows that the RIP is insufficient for explaining the success of compressed sensing in various practical applications. The second purpose of the paper is to introduce a new framework based on a generalised RIP-like definition that fits the applications where compressed sensing is used. We show that the shortcomings that show that uniform recovery is unreasonable no longer apply if we instead ask for structured recovery that is uniform only within each of the levels. To examine this phenomenon, a new tool, termed the 'Restricted Isometry Property in Levels' is described and analysed. Furthermore, we show that with certain conditions on the Restricted Isometry Property in Levels, a form of uniform recovery within each level is possible. Finally, we conclude the paper by providing examples that demonstrate the optimality of the results obtained.
Emotional modulation of attention orienting: A classical conditioning study

Emotional modulation of attention shifting was investigated in Posner’s (1980) spatial orienting task by conditioning the attention cue to an aversive white noise. Prior to the attention task, the Conditioning group received a 90dB white noise unconditioned stimulus (UCS) contingent upon the frame-lit rectangle attention cue, while the Control group received non-contingent presentations. The Conditioning group evidenced greater skin conductance responses to the frame-lit rectangle in the conditioning phase, reflecting an electrodermal conditioned response. In the attention phase, the frame-lit rectangle served as the attention cue in the spatial orienting task. The Conditioning group showed equally fast reaction times (RTs) to targets presented outside the location of the cue as to targets at the same location as the cue, reflecting elimination of the cognitive cost usually involved in shifting attention. The Control group evidenced the regular cost of shifting attention away from the location of the cue. The Conditioning group also evidenced a larger N1-component with a parietal distribution of the event-related brain potentials to the cue and a larger N1-component at the frontal regions to targets presented outside the cued location. This suggests that both visual orienting to the cue and attention shifting from cue to target on invalid trials were amplified by the emotional salience attached to the cue through the classical conditioning procedure.
Authentication Protocols for Internet of Things: A Comprehensive Survey

In this paper, a comprehensive survey of authentication protocols for Internet of Things (IoT) is presented. Specifically more than forty authentication protocols developed for or applied in the context of the IoT are selected and examined in detail. These protocols are categorized based on the target environment: (1) Machine to Machine Communications (M2M), (2) Internet of Vehicles (IoV), (3) Internet of Energy (IoE), and (4) Internet of Sensors (IoS). Threat models, countermeasures, and formal security verification techniques used in authentication protocols for the IoT are presented. In addition a taxonomy and comparison of authentication protocols that are developed for the IoT in terms of network model, specific security goals, main processes, computation complexity, and communication overhead are provided. Based on the current survey, open issues are identified and future research directions are proposed.
Polymorphonuclear Functions and Aging in Humans *

To determine whether normal aging interferes with the functional capability of polymorphonuclear leukocytes (PMNs), 6 tests of PMN function were performed in 285 healthy subjects whose ages ranged from 20 to 97 years. A second selection based upon blood measurements and a review of medical histories 6 months later, eliminated 68 subjects. The 217 remaining persons were sub‐classed by age into 7 groups including equal numbers of males and females. The functional properties of PMNs in the aged, when compared to those of younger adults, were characterized by: (a) a decrease in the chemotactic response in the 80+ age group; (b) increased adherence, with onset after age 70, maximal after age 80; (c) a progressive decrease of NBT dye reduction capability, up to age 70–79, followed by an unexplained increase of the mean value after age 80; (d) diminished Candida‐killing activity, appearing in the 60+ group and becoming lowest in the oldest group; and (e) lack of changes in spontaneous migration and endocytosis. The mechanisms by which this impairment occurs are hypothetical. It is proposed that normal PMNs, after leaving the bone marrow, are influenced by various humoral components such as metabolic byproducts or immune processes altered by aging. Thus the defective PMN may represent only another victim of the aging process.
Constant-Length Labeling Schemes for Deterministic Radio Broadcast

Broadcast is one of the fundamental network communication primitives. One node of a network, called the source, has a message that has to be learned by all other nodes. We consider broadcast in radio networks, modeled as simple undirected connected graphs with a distinguished source. Nodes communicate in synchronous rounds. In each round, a node can either transmit a message to all its neighbours, or stay silent and listen. At the receiving end, a node v hears a message from a neighbour w in a given round if v listens in this round and if w is its only neighbour that transmits in this round. If more than one neighbour of a node v transmits in a given round, we say that a collision occurs at v. We do not assume collision detection: in case of a collision, node v does not hear anything (except the background noise that it also hears when no neighbour transmits). We are interested in the feasibility of deterministic broadcast in radio networks. If nodes of the network do not have any labels, deterministic broadcast is impossible even in the four-cycle. On the other hand, if all nodes have distinct labels, then broadcast can be carried out, e.g., in a round-robin fashion, and hence O(łog n)-bit labels are sufficient for this task in n-node networks. In fact, O(łog Δ)-bit labels, where Δ is the maximum degree, are enough to broadcast successfully. Hence, it is natural to ask if very short labels are sufficient for broadcast. Our main result is a positive answer to this question. We show that every radio network can be labeled using 2 bits in such a way that broadcast can be accomplished by some universal deterministic algorithm that does not know the network topology nor any bound on its size. Moreover, at the expense of an extra bit in the labels, we can get the following additional strong property of our algorithm: there exists a common round in which all nodes know that broadcast has been completed.
CHANGES OF THE PRESPORE SPECIFIC STRUCTURE DURING DEDIFFERENTIATION AND CELL TYPE CONVERSION OF A SLIME MOLD CELL

In the slug of the cellular slime mold, Dictyostelium discoideum, are differentiated the anterior prestalk cells and the posterior prespore cells, whose differentiation is characterized by formation of the prespore specific vacuole (PSV). The ultrastructural changes of the PSV were investigated during dedifferentiation of a prespore cell disaggregated from a slug and also during conversion of the cell type, caused by fragmentation of a slug, between the prespore and the prestalk cells.
Reliability and Precision of Hip Proprioception Methods in Healthy Individuals

Objective:The goal of this study was to establish the intrasession and intersession reliability and precision of threshold to detect passive motion (TTDPM), force sense (FS), and active joint position sense (JPS) tests for the hip in healthy individuals. Design:Descriptive laboratory study. Setting:Research laboratory. Participants:Data were collected on 20 subjects between the ages of 18 and 30 years. They were physically active and had no history of major lower extremity injury or surgery or hip injuries. Interventions:Threshold to detect passive motion, FS, and active JPS were measured using a Biodex System 3 and a Vicon Motion Analysis System. Main Outcome Measures:Error scores were calculated as the absolute difference between the reference and reproduction values. Intraclass correlation (ICC) and standard error of measurement (SEM) were used to assess intrasession and intersession reliability and precision. Results:Adduction showed good reliability for JPS, with an intersession ICC (SEM) of 0.753 (0.248 degrees). For TTDPM, abduction showed an intrasession ICC (SEM) of 0.825 (0.256 degrees) and adduction had an intrasession ICC (SEM) of 0.765 (0.266 degrees). The intersession ICCs (SEM) were as follows: flexion 0.810 (0.143 degrees), extension 0.777 (0.195 degrees), abduction 0.906 (0.176 degrees), and adduction 0.893 (0.144 degrees). Flexion showed a good intersession ICC for FS: 0.764 (0.932 Nm). Conclusions:Results indicate that a reliable and precise method of measuring hip TTDPM has been established. Further investigation is necessary to develop reliable and precise measurement methods for FS and active JPS of the hip and to identify if TTDPM is related to hip kinematics, hip kinetics, and muscle activation about the hip during functional tasks.
Incidental Vocabulary Learning by Advanced Foreign Language Students: The Influence of Marginal Glosses, Dictionary Use, and Reoccurrence of Unknown Words

Dutch advanced students of French read a French short story in one of three text reading conditions: Marginal Glosses (provision of L1 translations of unknown words), Dictionary (opportunity to use a bilingual dictionary), or Control. After reading, students were tested for their recall of 16 words that had appeared either once or three times in the text. Support was found for the hypothesis that frequency of occurrence will foster incidental vocabulary learning more when advanced second language (L2) readers are given the meanings of unknown words through marginal glosses or when they look up meanings in a dictionary than when no external information concerning unknown words' meanings is available. In the former case, reappearance of a word will reinforce the form-meaning connection in the reader's mental lexicon. In the latter case, readers will often ignore unknown words or incorrectly infer their meanings, which will limit the frequency effect. This article ends with recommendations for teachers and researchers.
Plastic Hatching Timing by Red-Eyed Treefrog Embryos Interacts with Larval Predator Identity and Sublethal Predation to Affect Prey Morphology but Not Performance

Many animals respond to predation risk by altering their morphology, behavior, or life-history. We know a great deal about the cues prey respond to and the changes to prey that can be induced by predation risk, but less is known about how plastic responses to predators may be affected by separate plastic responses occurring earlier in life, particularly during the embryonic period. Embryos of a broad array of taxa can respond to egg- or larval-stage risks by altering hatching timing, which may alter the way organisms respond to future predators. Using the red-eyed treefrog (Agalychnis callidryas), a model for understanding the effects of plasticity across life-stages, we assessed how the combined effects of induced variation in the timing of embryo hatching and variation in the larval predator community impacted tadpole morphology, pigmentation and swimming performance. We found that A. callidryas tadpoles developed deeper tail muscles and fins and darker pigmentation in response to fish predators, either when alone or in diverse community with other predators. Tadpoles altered morphology much less so to dragonfly naiads or water bugs. Interestingly, morphological responses to predators were also affected by induced differences in hatching age, with early and late-hatched tadpoles exhibiting different allometric relationships between tail height and body length in different predator environments. Beyond induced morphological changes, fish predators often damaged tadpoles’ tails without killing them (i.e., sublethal predation), but these tadpoles swam equally quickly to those with fully intact tails. This was due to the fact that tadpoles with more damaged tails increased tail beats to achieve equal swimming speed. This study demonstrates that plastic phenotypic responses to predation risk can be influenced by a complex combination of responses to both the embryo and larval environments, but also that prey performance can be highly resilient to sublethal predation.
Cognitive Styles

Studies have indicated that the economically disadvantaged child has an impulsive, rather than a reflective, cognitive style. This impulsivity is similar to the behavior of the hyperkinetic, brain-injured child. Preschool programs for the disadvantaged have not taken account of the impulsivity of these children. It is suggested that further research be done to determine whether methods of teaching hyperactive, brain-injured children may be of value in teaching the disadvantaged
Fine-grained subjectivity and sentiment analysis: recognizing the intensity, polarity, and attitudes of private states

Private states (mental and emotional states) are part of the information that is conveyed in many forms of discourse. News articles often report emotional responses to news stories; editorials, reviews, and weblogs convey opinions and beliefs. This dissertation investigates the manual and automatic identification of linguistic expressions of private states in a corpus of news documents from the world press. A term for the linguistic expression of private states is subjectivity. The conceptual representation of private states used in this dissertation is that of (Wiebe, Wilson, and Cardie, 2005). As part of this research, annotators are trained to identify expressions of private states and their properties, such as the source and the intensity of the private state. This dissertation then extends the conceptual representation of private states to better model the attitudes and targets of private states. The inter-annotator agreement studies conducted for this dissertation show that the various concepts in the original and extended representation of private states can be reliably annotated. Exploring the automatic recognition of various types of private states is also a large part of this dissertation. Experiments are conducted that focus on three types of fine-grained subjectivity analysis: recognizing the intensity of clauses and sentences, recognizing the contextual polarity of words and phrases, and recognizing the attribution levels where sentiment and arguing attitudes are expressed. Various supervised machine learning algorithms are used to train automatic systems to perform each of these tasks. These experiments result in automatic systems for performing fine-grained subjectivity analysis that significantly outperform baseline systems. Keywords: Subjectivity, Private States, Opinions, Sentiment, Attitudes.
Real Wage, Labor Productivity, and Employment Trends in South Africa: A Closer Look

The paper looks at the dynamics of employment in South Africa and examines the factors that contributed to the job-shedding observed during the recent financial crisis. The paper finds that the rapid growth of the real wage, which outpaced the labor productivity growth in most sectors, played an important role in suppressing employment creation. The paper also finds that while there is a co-integrating link between the real wage and labor productivity, the deviations from equilibrium are persistent and thus contribute to a weak link between real wage growth and labor productivity growth in the short term. This finding is also supported by a cross-country analysis, which shows that in South Africa the link between the real wage and labor productivity is substantially weaker than in other emerging markets, even after controlling for labor market tightness indicators.
