Improving Circulatory Disturbance in Transient Abnormal Myelopoiesis

Transient abnormal myelopoiesis (TAM) in neonates with Down syndrome (DS) is characterized by circulating blast cells in the blood. TAM usually resolves spontaneously, but several studies have associated this condition with early death, focusing on the development of effective treatments. We report the case of a neonate with DS who had TAM and novel GATA1 mutation. Although the patient eventually died of hepatic failure, exchange blood transfusion and low-dose cytarabine treatment dramatically improved pulmonary hypertension and acute renal failure refractory to conventional therapy. Such a blast-reducing approach might be useful for improving circulatory disturbances in neonates with DS and TAM.
The Role of Social Media for Collaborative Learning to Improve Academic Performance of Students and Researchers in Malaysian Higher Education.

Social media is widely considered to improve collaborative learning among students and researchers. However, there is a surprising lack of empirical research in Malaysian higher education to improve performance of students and researchers through the effective use of social media that facilitates desirable outcomes. Thus, this study offers a review of the empirical literature, and its distinctiveness stems from the focus on collaborative learning and engagement to understand the interactive factors relevant that affect academic performance. This study also explores factors that contribute to the enhancement of collaborative learning and engagement through social media. It is unique in that it highlights that the effective use of social media for collaborative learning, engagement, and intention to use social media" - a phenomenon that relies on the theory of social constructivist learning. The findings showed that collaborative learning, engagement, and intention to use social media positively and significantly relate to the interactivity of research group members with peers and research students with supervisors to improve their academic performance in Malaysian higher education.
Mesh Networks : a Model-based Approach

We address the problem of identifying high throughput paths in 802.11 wireless mesh networks. We introduce an analytical model that accurately captures the 802.11 MAC protocol operation and predicts both throughput and delay of multi-hop flows under changing traffic load or routing decisions. The main idea is to characterize each link by the packet loss probability and by the fraction of busy time sensed by the link transmitter, and to capture both intra-flow and inter-flow interference. Our model reveals that the busy time fraction experienced by a node, a locally measurable quantity, is essential in finding maximum throughput paths. Furthermore, metrics that do not take this quantity into account can yield low throughput by routing over congested paths or by filtering-out non-congested paths. Based on our analytical model, we propose a novel routing metric that can be used to discover high throughput path in a congested network. Using city-wide mesh network topologies we demonstrate that our model-based metric can achieve significant performance gains with respect to existing metrics.
What do referential communication tasks measure? A study of children with specific language impairment

ABSTRACT A group of 54 children with specific language impairment was compared with a control group on a referential communication task in which the child was asked to describe a picture from an array of eight similar items so that the listener could identify it. The language-impaired children performed more poorly than age-matched controls. However, there was no relationship between referential communication performance and conversational ability. Children who provided excessive and irrelevant information in conversation did not show the same characteristics in the experimental setting. Formal task requirements, such as the need to scan an array, appeared to be a major determinant of performance on structured referential communication tasks. These tasks are not sensitive to the types of pragmatic difficulty that some children have in open-ended conversation.
Functional status of the articularis genus muscle in individuals with knee osteoarthritis

Objectives: To clarify the functional status of the articularis genus muscle (AGM) in individuals with knee osteoarthritis (OA) and to analyze the muscle’s relationship with knee OA. Methods: Fifty-two individuals with knee OA (mean age, 73.4 years), 50 elderly individuals without knee OA changes (mean age, 71.2 years) and 75 young individuals (mean age, 20.2 years) were observed the AGM using ultrasonography. The thickness of the AGM, the anteroposterior distance of the suprapatellar bursa, and moving distance of the muscle insertion were measured both at rest and during isometric contraction, and values during contraction were expressed as percentages of the values at rest (%Muscle-Increase, %Bursa-Increase). Results: Muscle thickness at rest, %Muscle-Increase, %Bursa-Increase, and moving distance of the muscle insertion were significantly lower and anteroposterior distance of the suprapatellar bursa was significantly higher in the OA group than in the controls (p < 0.001, all). In the OA group, these values for the AGM were significantly correlated with knee range of motion, knee pain, and Kellgren and Lawrence grade. Conclusions: Individuals with knee OA exhibited atrophic changes and dysfunctions of the AGM, and these were associated with symptoms. Atrophic changes and dysfunctions of the AGM may be specific changes associated with knee OA.
The Evolution of War and its Cognitive Foundations

Coalitional aggression evolved because it allowed participants in such coalitions to promote their fitness by gaining access to disputed reproduction enhancing resources that would otherwise be denied to them. Far fewer species manifest coalitional aggression than would be expected on the basis of the actual distribution of social conditions that would favor its evolution. The exploitation of such opportunities depends on the solution by individuals of highly complex and specialized information processing problems of cooperation and social exchange, and the difficulty of evolving cognitive mechanisms capable of solving such complex computational tasks may account for the phylogenetic rarity of such multi-individual coalitions. We propose that humans and a few other cognitively pre-adapted species have evolved specialized cognitive programs, that govern coalitional behavior, and constitute a distinctive coalitional psychology. An adaptive task analysis of what such algorithms need to accomplish, in the decisions regulating coalition formation, participation, cost and benefit allocation, allows the preliminary mapping of this coalitional psychology. Scrutinization of the adaptive features of coalitional aggression reveals some surprising characteristics, including that, under certain conditions, mortality rates do not negatively impact the fitness of males in the coalition, suggesting why warfare is so favored an activity, despite its risks to participating individuals' welfare.
In vivo induction of insulin secretion by ornithine alpha-ketoglutarate: involvement of nitric oxide and glutamine.

We previously demonstrated that ornithine alpha-ketoglutarate (OKG), known for its anabolic properties, induces insulin secretion in vitro. The present study was undertaken to further characterize this effect in vivo and investigate a possible interaction with glucose both in vivo and in vitro. Male Wistar rats received an intravenous bolus of OKG (25 mg/kg) and/or glucose (0.8 g/kg) or saline, and their plasma insulin and glucose levels were monitored for 30 minutes. OKG alone increased plasma insulin to a similar extent to glucose. In combination with glucose, OKG significantly increased glucose-induced insulin secretion in vivo and in vitro, and led to a significant increase in glucose utilization in vivo. The absence of significant variations in plasma arginine and glutamine suggests a direct effect of OKG on the pancreas. To assess the involvement of the synthesis of nitric oxide and glutamine in OKG-induced insulin secretion, the experiments were repeated in the presence of inhibitors of these 2 pathways, respectively L-nitroarginine-methylester (L-NAME) and methionine sulfoximine (MSO). Both inhibitors were able significantly to reduce OKG-induced insulin secretion without affecting either basal or glucose-induced insulin release. Thus OKG acts directly with glucose on islets to induce insulin secretion via mechanisms involving NO and glutamine synthesis. In addition, our results suggest that OKG and glucose act via separate pathways.
Articulating Blind Touch: Thinking through the Feet

ABSTRACT Through reference to autobiographies of blindness and interview material with members of specialist blind and visually impaired walking groups this article aims to explore some of the problems of talking about the experience of touch. It reflects on how people with blindness are receptive to and articulate tactile impressions, and consideration is given to how the articulation of touch relates to certain discourses and stereotypes of touch and blindness. In so doing, the article highlights some of the ways in which the embodied experience of touch is mediated through language and makes the simple point that language does not simply convey tactile experience, it mediates its expression. With this research “problem” in mind I turn to how some interview participants drew attention to their feet—transcending the stereotype of blind touch as primarily associated with the hand. Some of the ways in which the impressions of the feet are talked about by people with blindness are revealed, including the way in which feet are part of embodied processes of immersion and forgetting as well as a source of contemplation, humor, visualization, and dreams.
A theoretical and experimental analysis of polymerization shrinkage of bone cement: A potential major source of porosity.

A theoretical basis for understanding polymerization shrinkage of bone cement is presented based on density changes in converting monomer to polymer. Also, an experimental method, based on dilatometry and the Archimedes' principle is presented for highly precise and accurate measurement of unconstrained volumetric shrinkage of bone cement. Furthermore, a theoretical and experimental analysis of polymerization shrinkage in a constrained deformational state is presented to demonstrate that porosity can develop due to shrinkage. Six bone-cement conditions (Simplex-Ptrade mark vacuum and hand mixed, Endurancetrade mark vacuum mixed, and three two-solution experimental bone cements with higher initial monomer levels) were tested for volumetric shrinkage. It was found that shrinkage varied statistically (p< or = 0.05) from 5.1% (hand-mixed Simplex-Ptrade mark) to 6.7% (vacuum-mixed Simplex-Ptrade mark) to 10.5% for a 0.6:1 (polymer g/monomer mL) two-solution bone cement. Shrinkage was highly correlated with initial monomer content (R(2) = 0.912) but with a lower than theoretically expected rate. This discrepancy was due to the presence of residual monomer after polymerization. Using previously determined residual monomer levels, the theoretic shrinkage analysis was shown to be predictive of the shrinkage results with some residual monomer left after polymerization. Polymerization of a two-solution bone cement in a constrained state resulted in pores developing with volumes predicted by the theory that they are the result of shrinkage. The results of this study show that shrinkage of bone cement under certain constrained conditions may result in the development of porosity at the implant-bone cement interface and elsewhere in the polymerizing cement mantle.
Turning Lemons into Lemonade

Authors need to view reviewers’ comments not as judgments about the value of their work, but as good data about potential readers of their articles. The editorial review process does have deficiencies, the most serious being that reviewers should decide what articles warrant publication. “Peer review” should mean that reviewers and authors are indeed peers. However, editors typically act as if reviewers have more competence and more valid opinions than authors, and as if they themselves have the wisdom and knowledge to impose constraints on manuscripts. Empirical evidence indicates that editorial decisions incorporate bias and randomness. However, authors need to persuade potential readers to read their articles and that authors’ ideas and theories are plausible and useful. Authors must adapt their manuscripts to readers’ perceptual frameworks. Nevertheless, authors should remember that editors and reviewers are not superior and that the ultimate decisions about what is right must come from inside themselves.
A High-Precision Micropipette Sensor for Cellular-Level Real-Time Thermal Characterization

We report herein development of a novel glass micropipette thermal sensor fabricated in a cost-effective manner, which is capable of measuring steady thermal fluctuation at spatial resolution of ∼2 μm with an accuracy of ±0.01 °C. We produced and tested various micrometer-sized sensors, ranging from 2 μm to 30 μm. The sensor comprises unleaded low-melting-point solder alloy (Sn-based) as a core metal inside a pulled borosilicate glass pipette and a thin film of nickel coating outside, creating a thermocouple junction at the tip. The sensor was calibrated using a thermally insulated calibration chamber, the temperature of which can be controlled with an accuracy of ±0.01 °C, and the thermoelectric power (Seebeck coefficient) of the sensor was recorded from 8.46 to 8.86 μV/°C. We have demonstrated the capability of measuring temperatures at a cellular level by inserting our temperature sensor into the membrane of a live retinal pigment epithelium cell subjected to a laser beam with a focal spot of 6 μm. We measured transient temperature profiles and the maximum temperatures were in the range of 38–55 ± 0.5 °C.
Tool Support for Distributed Pair Programming Dissertation Proposal

In pair programming, two software developers share a single computer monitor and keyboard. One of the developers, called the driver, controls the computer keyboard and mouse. The driver is responsible for entering software design, source code, and test cases. The second developer, called the navigator, examines the driver’s work, offering advice, suggesting corrections, and assisting with design decisions. The developers switch roles at regular intervals. Although role switching is an informal process, a typical interval is 20 minutes.
The effects of question type on self‐contradictions by children in the course of forensic interviews

Twenty-four forensic interviews of seven alleged victims of child sexual abuse were examined to elucidate the circumstances in which the children contradicted forensically relevant details they had provided earlier. Suggestive questions by the interviewers elicited a disproportionate number of contradictions, whereas open-ended invitations never elicited contradictions. Because contradictions necessarily imply that details were stated inaccurately at least once, these close analyses of forensic interviews demonstrate that, as in analogue contexts, open-ended prompts yield more accurate information than do focused questions, particularly option-posing and suggestive prompts.

EEG-Korrelate der Aufmerksamkeit bei Gesunden und Patienten mit Hirnschädigung

In der vorliegenden Untersuchung sollte gepruft werden, inwieweit die Theta-Beta-Ratio ein geeignetes Mas fur Neurofeedback ist. Bei einer Gruppe Gesunder sowie einer Gruppe hirngeschadigter Patienten wurde hierzu eine Einzelsitzung Neurofeedback mit der Theta-Beta-Ratio als Feedbackparameter durchgefuhrt. Im Anschluss mussten die Probanden einen Test zur Daueraufmerksamkeit absolvieren. Die Ergebnisse der gesunder Probanden zeigen statistisch signifikante Korrelationen zwischen der Theta-Beta-Ratio und der Anzahl richtiger und falscher Reaktionen sowie der Theta-Beta-Ratio und der Reaktionszeit. Hirngeschadigte Patienten zeigten wie die gesunden Versuchspersonen eine statistisch signifikante Korrelation zwischen der Theta-Beta-Ratio und der Fehlerzahl. Der gefundene Zusammenhang zwischen der Theta-Beta-Ratio und den Leistungen in dem Test zur Daueraufmerksamkeit zeigt, dass der Quotient aus Theta- und Beta-Aktivitat ein geeigneter Parameter fur Neurofeedback ist.
INTEGRATING RESEARCH PROJECTS INTO FIELD WORK EXPERIENCES: ENHANCED TRAINING FOR UNDERGRADUATE GERIATRIC SOCIAL WORK STUDENTS

The aging of the U.S. population is creating a growing need for well-trained social workers to serve aging clients and their families. The needs of these clients are often multidimensional, requiring practitioners who are well trained in understanding and applying complex theory, research findings, and practice approaches. Unfortunately, several factors impede best case scenarios in geriatric social work education. These include limited opportunities to study or specialize in aging, a smaller than optimal proportion of social work students seeking such training, and students' frequent fearfulness of research courses and their first practicum field experience. This paper suggests that we can more effectively train social work practitioners (as well as researchers and administrators) by modifying the common practice of teaching research and practice in distinct and separate courses. Specifically, we advocate the addition of an applied research component to the field work portion of students' training. The s.
High-Performance InGaN-Based Green Resonant-Cavity Light-Emitting Diodes for Plastic Optical Fiber Applications

High-performance InGaN-based green resonant-cavity light-emitting diodes (RCLEDs) with a plating Cu substrate for plastic optical fiber communication applications are reported. Good stability of emission wavelength was obtained at 0.016 nm/mA . The RCLEDs presents low temperature dependence, showing only a 3% drop in light output power as the temperature increasing from 25 to 85degC. The superior performance can be attributed to the decreased dynamic series resistance and the enhanced thermal dissipation of the heat sink substrate.
Micro-Architectural Analysis of Time-Driven Cache Attacks: Quest for the Ideal Implementation

Time-driven attacks on the data cache are a lethal form of cryptanalytic attacks for block-ciphers implemented with look-up tables. The difference of means (DOM) observed in the execution time of a block cipher is often used as a distinguisher to glean information about the secret key. The root cause for the distinguisher to work has long been attributed to the number of cache-misses that occur during the encryption. In this paper, we show that micro-architectural acceleration features in cache memories that are used to reduce miss-penalty (such as pipelining, parallelism, out-of-order, and non-blocking memory accesses) contribute significantly to the leakage. We develop a framework to analyze the DOM distinguisher considering architectural as well as micro-architectural acceleration components in the cache memory. Our findings, which are experimentally verified, show that the two contributing leakage factors (namely the number of cache misses and the micro-architectural acceleration features) affect the DOM in opposite directions. One leakage source results in a positive DOM while the other causes a negative DOM. This opposing characteristic of the leakages makes it feasible to implement block ciphers in a way such that the two leakages cancel each other, thus leading to implementations with higher resistance against time-driven cache-attacks.
Inositol phosphates in the environment.

The inositol phosphates are a group of organic phosphorus compounds found widely in the natural environment, but that represent the greatest gap in our understanding of the global phosphorus cycle. They exist as inositols in various states of phosphorylation (bound to between one and six phosphate groups) and isomeric forms (e.g. myo, D-chiro, scyllo, neo), although myo-inositol hexakisphosphate is by far the most prevalent form in nature. In terrestrial environments, inositol phosphates are principally derived from plants and accumulate in soils to become the dominant class of organic phosphorus compounds. Inositol phosphates are also present in large amounts in aquatic environments, where they may contribute to eutrophication. Despite the prevalence of inositol phosphates in the environment, their cycling, mobility and bioavailability are poorly understood. This is largely related to analytical difficulties associated with the extraction, separation and detection of inositol phosphates in environmental samples. This review summarizes the current knowledge of inositol phosphates in the environment and the analytical techniques currently available for their detection in environmental samples. Recent advances in technology, such as the development of suitable chromatographic and capillary electrophoresis separation techniques, should help to elucidate some of the more pertinent questions regarding inositol phosphates in the natural environment.
Teachers’ classroom‐based action research

Teachers’ classroom‐based action research is sometimes misunderstood by those who undertake it and support it, in three respects. First, it is wrongly assumed to fall into either positivist or interpretive paradigms (or perhaps a mixture of both) or to be critical. Second, there is little understanding as to why action research is necessarily self‐reflexive, collaborative and political. Third, there is a view that classroom research studies are not suitable for dissemination because they are not generalizable. Drawing on the work of Heron and Reason, I outline a view of how teachers are positioned in their classroom to explain why teachers’ classroom‐based action research cannot be underpinned by positivist, interpretive or critical paradigms, is necessarily self‐reflexive, collaborative (albeit in a weak form) and political and is suitable for dissemination to teachers, working in similar contexts.
The Dynamics of Trade Unionism and National Economic Performance

I test two theories of the political processes of trade unions. The first argues that wage moderation depends on a centralized labor movement. The second contends that, institutional conditions permitting, unions' coordination of bargaining strategies is sufficient. Coordination is most likely to he achieved when there are small number of unions that do not compete for members, that is, when union monopoly is high. Important empirical anomalies may be resolved by analyzing the effects of union centralization and monopoly separately, rather than combining them into a composite index of corporatism. Reanalyzing comparative data from Organization of Economic Cooperation and Development countries between 1963 and 1985 largely corroborates the hypothesis that monopoly is more important than either centralization or composite indices of corporatism for national economic performance. The conceptual rationale underlying indices of corporatism should be reexamined.
Moving Object Detection for Video Surveillance using Different Color Spaces

In many vision based application identifying moving objects is important and critical task. For different computer vision application Background subtraction is fast way to detect moving object. Background subtraction separates the foreground from background. However, during background subtraction pixels belonging to shadow are misclassified as foreground object. Moving cast shadow associated with moving object also gets detected making it challenge for video surveillance. Now days many methods are available for background subtraction. The core of background subtraction is background modeling. Gaussian Mixture model is good balance between accuracy and complexity. However, it is difficult to determine the optimal color space in which to remove shadow. In this paper, we study the features of moving object and shadow in different color spaces to solve the problem.
