iPOD THEREFORE I CAN: ENHANCING THE LEARNING OF CHILDREN WITH INTELLECTUAL DISABILITIES THROUGH EMERGING TECHNOLOGIES

This paper explores the pedagogical and social potential of emerging technologies, in particular the iPod, in facilitating the learning of young Australians with severe intellectual and social disabilities. The study, which was carried out in a segregated educational setting in Victoria, Australia, sought to establish whether the intrinsic portable, multi-media capabilities of the iPod particularly lent themselves to a practical application for students with severe disabilities. It was concluded that such new technology has considerable power and potential as an emerging pedagogy with students with severe intellectual and physical disabilities.
Multi-class AdaBoost with Hypothesis Margin

Most AdaBoost algorithms for multi-class problems have to decompose the multi-class classification into multiple binary problems, like the Adaboost.MH and the LogitBoost. This paper proposes a new multi-class AdaBoost algorithm based on hypothesis margin, called AdaBoost.HM, which directly combines multi-class weak classifiers. The hypothesis margin maximizes the output about the positive class meanwhile minimizes the maximal outputs about the negative classes. We discuss the upper bound of the training error about AdaBoost.HM and a previous multi-class learning algorithm AdaBoost.M1. Our experiments using feed forward neural networks as weak learners show that the proposed AdaBoost.HM yields higher classification accuracies than the AdaBoost.M1 and the AdaBoost.MH, and meanwhile, AdaBoost.HM is computationally efficient in training.
Anarchy, Power, and Poststructuralism

In 1994 Todd May initiated a new turn in contemporary theory– poststructuralist anarchism, commonly abbreviated to “postanarchism. ” May’s seminal study, The Political Philosophy of Poststructuralist Anarchism called attention to ways in which the political philosophy of anarchism echoes the concerns of poststructuralist thought, notably in its critique of oppression. Taking aim at Marxism, he (rightly) argued that anarchism has a more sophisticated grasp of how oppression disperses across the social field. According to May, Marxists did not address the hierarchical relations sustaining this state of affairs. Instead, they called for the seizure of the reigns of power by a benighted proletariat that would subordinate society to its will by restructuring economic relations in the image of socialism (49). 1 Historically, anarchists opposed this, because they were suspicious of any social formation, however well intentioned, exercising power over others. Anarchism interrogated relations of domination with the goal of destroying all representational forms of power, precisely because such politics are always already at one remove from the represented (May, 50). However, as a corollary to his praise for this thorough-going attack on domination in all its forms, May argued that anarchism (theoretically) was not up to the task of realizing its political potential. Referencing “classical” figures from the nineteenth-century European wing of the movement, May suggested that anarchists had yet to come to terms with power as a positive ground for action. The anarchist project, he argued, is based on a fallacious “humanist” notion that “the human essence is a good essence, which relations of power suppress and deny. ” This impoverished notion of power as ever oppressive, never productive, was the Achilles heel of anarchist political philosophy (ibid., 62). Hence May’s call for a new and improved “poststructuralist anarchism. ” The
Short-Term Effect of Nutrient Availability and Rainfall Distribution on Biomass Production and Leaf Nutrient Content of Savanna Tree Species

Changes in land use may lead to increased soil nutrient levels in many ecosystems (e.g. due to intensification of agricultural fertilizer use). Plant species differ widely in their response to differences in soil nutrients, and for savannas it is uncertain how this nutrient enrichment will affect plant community dynamics. We set up a large controlled short-term experiment in a semi-arid savanna to test how water supply (even water supply vs. natural rainfall) and nutrient availability (no fertilisation vs. fertilisation) affects seedlings’ above-ground biomass production and leaf-nutrient concentrations (N, P and K) of broad-leafed and fine-leafed tree species. Contrary to expectations, neither changes in water supply nor changes in soil nutrient level affected biomass production of the studied species. By contrast, leaf-nutrient concentration did change significantly. Under regular water supply, soil nutrient addition increased the leaf phosphorus concentration of both fine-leafed and broad-leafed species. However, under uneven water supply, leaf nitrogen and phosphorus concentration declined with soil nutrient supply, this effect being more accentuated in broad-leafed species. Leaf potassium concentration of broad-leafed species was lower when growing under constant water supply, especially when no NPK fertilizer was applied. We found that changes in environmental factors can affect leaf quality, indicating a potential interactive effect between land-use changes and environmental changes on savanna vegetation: under more uneven rainfall patterns within the growing season, leaf quality of tree seedlings for a number of species can change as a response to changes in nutrient levels, even if overall plant biomass does not change. Such changes might affect herbivore pressure on trees and thus savanna plant community dynamics. Although longer term experiments would be essential to test such potential effects of eutrophication via changes in leaf nutrient concentration, our findings provide important insights that can help guide management plans that aim to preserve savanna biodiversity.
The Fate of the Dramatic in Modern Society: Social Theory and the Theatrical Avant-Garde

Avant-garde theatre is often invoked as the bellwether for a society that has become postdramatic – fragmented, alienated, and critical of efforts to create collectively shared meanings. A theatre whose sequenced actions have no narrative (so the story goes) mirrors a social world where the most conflictual situations no longer appear as drama but merely as spectacle: a society where audiences look on without any feeling or connection. Because only half right, these theses about postdramatic theatre and society are fundamentally wrong. As modern societies have expanded and differentiated, the elements that compose performances have become separated and often fragmented in both theatre and society. If they can be brought back together again, performances are viewed as authentic and meaningful. If (re)fusion cannot be achieved, performances fail to communicate meaning. The aim of this essay is to demonstrate that a shared ambition to (re)fuse fragmented performative elements has defined the most important strain of avant-garde theatre over the last two centuries. Most radical theatrical innovation has sought to open live drama back up to the telos of myth and ritual. Neither in theatre nor social life can the world transcend dramaturgy; it is fundamental to the search for meaning in a world beyond cosmological religion.
MEASUREMENT OF RESONANT FREQUENCY AND QUALITY FACTOR OF MICROWAVE RESONATORS : COMPARISON OF METHODS

Precise microwave measurements of sample conductivity, dielectric, and magnetic properties are routinely performed with cavity perturbation measurements. These methods require the accurate determination of quality factor and resonant frequency of microwave resonators. Seven different methods to determine the resonant frequency and quality factor from complex transmission coefficient data are discussed and compared to find which is most accurate and precise when tested using identical data. We find that the nonlinear least-squares fit to the phase versus frequency is the most accurate and precise when the signal-to-noise ratio is greater than 65. For noisier data, the nonlinear least-squares fit to a Lorentzian curve is more accurate and precise. The results are general and can be applied to the analysis of many kinds of resonant phenomena.
Realization of RF Distance Bounding

One of the main obstacles for the wider deployment of radio (RF) distance bounding is the lack of platforms that implement these protocols. We address this problem and we build a prototype system that demonstrates that radio distance bounding protocols can be implemented to match the strict processing that these protocols require. Our system implements a prover that is able to receive, process and transmit signals in less than 1ns. The security guarantee that a distance bounding protocol built on top of this system therefore provides is that a malicious prover can, at most, pretend to be about 15cm closer to the verifier than it really is. To enable such fast processing at the prover, we use specially implemented concatenation as the prover's processing function and show how it can be integrated into a distance bounding protocol. Finally, we show that functions such as XOR and the comparison function, that were used in a number of previously proposed distance bounding protocols, are not best suited for the implementation of radio distance bounding.
Spastin Couples Microtubule Severing to Membrane Traffic in Completion of Cytokinesis and Secretion

Mutations in the gene encoding the microtubule (MT)‐severing protein spastin are the most common cause of hereditary spastic paraplegia, a genetic condition in which axons of the corticospinal tracts degenerate. We show that not only does endogenous spastin colocalize with MTs, but that it is also located on the early secretory pathway, can be recruited to endosomes and is present in the cytokinetic midbody. Spastin has two main isoforms, a 68 kD full‐length isoform and a 60 kD short form. These two isoforms preferentially localize to different membrane traffic pathways with 68 kD spastin being principally located at the early secretory pathway, where it regulates endoplasmic reticulum‐to‐Golgi traffic. Sixty kiloDalton spastin is the major form recruited to endosomes and is also present in the midbody, where its localization requires the endosomal sorting complex required for transport‐III‐interacting MIT domain. Loss of midbody MTs accompanies the abscission stage of cytokinesis. In cells lacking spastin, a MT disruption event that normally accompanies abscission does not occur and abscission fails. We suggest that this event represents spastin‐mediated MT severing. Our results support a model in which membrane traffic and MT regulation are coupled through spastin. This model is relevant in the axon, where there also is co‐ordinated MT regulation and membrane traffic.
In vitro Analysis of Antioxidant, Antimicrobial and Antiproliferative Activity of Enteromorpha antenna, Enteromorpha linza and Gracilaria corticata Extracts

Background Seaweeds are taxonomically diverse benthic algae, which are rich in bioactive compounds. These compounds have a potential application in medicine. Objectives The aim of the study was to investigate the bioactive properties of three seaweed samples, Enteromorpha antenna, Enteromorpha linza and Gracilaria corticata were collected from the shoreline of Mahabalipuram, Tamilnadu. Materials and Methods Bioactive components were extracted by using various solvents. Antioxidant analysis methods like scavenging activity of nitric oxide, hydrogen peroxide, hydroxyl radicals, free radical scavenging (DPPH), FRAP (ferric reducing ability plasma) ability and reducing power were carried out. MTT assay was employed to study the anticancer activity against cancer cell lines Hep-G2, MCF7 and normal VERO cell lines. Results It was found that methanolic extracts elicited higher total phenolic content, higher percentage scavenging activity of nitric oxide, hydrogen peroxide, hydroxyl radicals, free radical scavenging (DPPH), FRAP (ferric reducing ability plasma) ability and reducing power. Different concentrations of crude methanolic extracts of seaweeds showed potential antimicrobial activity by well diffusion method. Crude methanolic extract of G. corticata had significant anticancer activity followed by E. antenna and E. linza on cancer cell lines Hep-G2, MCF7 and normal VERO cell lines by MTT assay. Conclusions The methanolic extracts of seaweeds Enteromorpha antenna, Enteromorpha linza and Gracilaria corticata possess high total phenolic content and shows a good free radical scavenging activity and hence are proven to have better antioxidant activity and they might be good candidates for further investigations in order to develop potential anticancer drugs.

The research was aimed at proving whether diary writing is effective to improve students’ skill in writing recount text or not. The research was pre-experimental research design. The population of this research was the tenth grade students at SMA Alkhairaat Kalukubula and the sample was class XA. The number of the sample was 25 students. The researcher employed cluster sampling and adopted one group pre-test and post-test design. The pre-test was used to measure the students’ skill in writing recount text before treatment, and post-test was used to measure the students’ skill after the treatment. Based on the result of both tests, the researcher found that the t-counted was 8.56. The level of significance counted is set up at 0.05 and the degree of freedom (df) of the table is 25 – 1 = 24. The researcher found that t-table was 2.064. It showed that t-counted was higher than the t-table. It means that the hypothesis of this research is accepted. In conclusion, the use of diary writing was effective to improve the students’ skill in writing recount text. Keywords : Writing Skill; Recount Text; Diary Writing.
BayesDB: A probabilistic programming system for querying the probable implications of data

Is it possible to make statistical inference broadly accessible to non-statisticians without sacrificing mathematical rigor or inference quality? This paper describes BayesDB, a probabilistic programming platform that aims to enable users to query the probable implications of their data as directly as SQL databases enable them to query the data itself. This paper focuses on four aspects of BayesDB: (i) BQL, an SQL-like query language for Bayesian data analysis, that answers queries by averaging over an implicit space of probabilistic models; (ii) techniques for implementing BQL using a broad class of multivariate probabilistic models; (iii) a semi-parametric Bayesian model-builder that auomatically builds ensembles of factorial mixture models to serve as baselines; and (iv) MML, a "meta-modeling" language for imposing qualitative constraints on the model-builder and combining baseline models with custom algorithmic and statistical models that can be implemented in external software. BayesDB is illustrated using three applications: cleaning and exploring a public database of Earth satellites; assessing the evidence for temporal dependence between macroeconomic indicators; and analyzing a salary survey.
A 3.1–4.8-GHz IR-UWB All-Digital Pulse Generator With Variable Channel Selection in 0.13-$\mu\hbox{m}$ CMOS Technology

An all-digital pulse generator in a standard 0.13- CMOS technology for communication systems using an impulse radio ultrawideband signal is presented. A delay-line-based architecture utilizing only static logic gates for pulse generation with low-power characteristic is proposed in this brief. The center frequency and the fixed bandwidth of 500 MHz of the output signal can be digitally controlled to cover three channels in the low band of UWB spectrum. Delay-based binary phase shift keying and pulse position modulation schemes are exploited at the same time to modulate transmitted signals with further improvement in spectrum characteristics. The total energy consumption is 48 pJ/pulse at 1.2-V supply voltage without static bias currents.
Trends in fluorescence imaging and related techniques to unravel biological information

Optical microscopy is among the most powerful tools that the physical sciences have ever provided biology. It is indispensable for basic lab work, as well as for cutting edge research, as the visual monitoring of life processes still belongs to the most compelling evidences for a multitude of biomedical applications. Along with the rapid development of new probes and methods for the analysis of laser induced fluorescence, optical microscopy over past years experienced a vast increase of both new techniques and novel combinations of established methods to study biological processes with unprecedented spatial and temporal precision. On the one hand, major technical advances have significantly improved spatial resolution. On the other hand, life scientists are moving toward three‐ and even four‐dimensional cell biology and biophysics involving time as a crucial coordinate to quantitatively understand living specimen. Monitoring the whole cell or tissue in real time, rather than producing snap‐shot‐like two‐dimensional projections, will enable more physiological and, thus, more clinically relevant experiments, whereas an increase in temporal resolution facilitates monitoring fast nonperiodic processes as well as the quantitative analysis of characteristic dynamics.
Enterohemorrhagic Escherichia coli effector EspL2 induces actin microfilament aggregation through annexin 2 activation

Enterohemorrhagic Escherichia coli (EHEC) delivers virulence factors into host cells through the type III secretion system (T3SS) to exert the bacterial pathogenicity. EHEC encodes more than 20 type III secretion system‐delivered families of effectors that have different functions at different infectious stages and enable a successful infection. One of them, EspL2, is encoded on the SpLE3 phage‐like element in EHEC O157:H7 Sakai and is well conserved among various EHEC strains. Here we show that, after delivery into host cells, EspL2 accumulated under adherent bacteria, as did polymerized F‐actin. EspL2‐expressing EHEC formed three‐dimensional, condensed microcolonies, into which the host cell extended plasma membrane protrusions on an F‐actin‐rich cytoskeleton. EspL2 bound F‐actin‐aggregating annexin 2 directly, increasing its activity. In addition, annexin 2 depletion abolished the EspL2‐dependent formation of condensed microcolonies and F‐actin aggregation. The EspL2‐induced pseudopod‐like protrusion of the host plasma membrane interacted with and supported colonization by the bacteria, independent of Tir‐mediated actin polymerization. Thus, EspL2 supports efficient colonization by increasing annexin 2's ability to aggregate Tir‐induced F‐actin and by modifying the morphology of the host cell membrane.
Affective Disturbance in Eating Disorders

Thirty-three bulimic and 14 restrictive anorexics were compared on DSM-III diagnoses of affective and anxiety disorders, observer-rated and self-rated measures of depression and anxiety, and family history. A subgroup of 18 eating disorder subjects was administered the dexamethsone suppression test. The same 18 subjects were compared to 13 subjects with affective disorder on the Schedule for Affective Disorders and Schizophrenia. It was found that a large group with bulimia and restrictive anorexia nervosa was subject to a depressive disorder. Thirty-eight percent of the sample fulfilled criteria for a major depressive episode. The dysphoric experience seemed as intense in the bulimic and restricter group. There was a high incidence of dexamethasone nonsuppression (55%), which was found to be related to various measures of depression. Bulimics and restricters differed in their family history of affective disorder. While 61% of bulimics had a positive history of depression, this was found in only 23% of restricters (p < .03).
Bidding against an unknown number of competitors sharing affiliated information

In the general symmetric model of Milgrom and Weber, equilibrium bidding is analyzed with a stochastic number of bidders. the equilibrium strategies generalize the known expressions in a coherent way. For the equilibrium bid function of the first price auction, an interpretation involving 'marginal winning probabilities' is proposed. With ageneralized version of the linkage principle, the well-known revenue ranking theorems extend to a stochastic number of bidders. As an application, we show that the seller's generically optimal information policy regarding the number of competitors is concealing the information.
THE DEVELOPMENT OF AGGRESSION FROM AGES 2 TO 9.5 IN A HIGH RISK SAMPLE OF MALES AND FEMALES: SIMILARITIES AND DIFFERENCES IN PATTERNS, PREDICTORS, AND OUTCOMES

Abstract Sex differences in base rates of aggression are well-established, with males showing higher levels from preschool-age through adulthood. Research investigating the etiology of these sex differences in base rates of aggression has the potential to inform basic science and prevention. A growing body of work has produced relatively consistent results showing that boys possess a greater number of child-level risk factors for aggression beginning in early childhood; however, findings are less consistent with respect to whether associations between risk and aggression are stronger in boys than in girls. The current study aimed to advance our understanding of associations between early childhood risk and the development of aggressive behavior, as well as the middle childhood consequences of early-starting aggression, in a sample of 731 boys and girls recruited at age 2 for being at high risk of developing conduct problems. Children were followed longitudinally to age 10.5 utilizing multiple data collection techniques including parent and teacher reports, home observation, and structured assessments of child behavior and parent-child interaction. The findings showed that a small proportion of both sexes exhibited high and persistent trajectories of aggression from early to middle childhood and that boys (13.3%) were more likely to exhibit this pattern than girls (6.9%). Toddler-age child-level risk factors for aggression (e.g., low inhibitory control, language delays) were more prevalent in boys than in girls, but no sex differences were observed with respect to base rates of contextual risk factors (e.g., parent depression, parent-child coercion). Associations between toddler-age risk and trajectories of high persistent aggression were not stronger in boys than in girls. A pattern of high persistent aggressive behavior was associated with a broad array of impairments during middle childhood for both sexes, including externalizing and internalizing problems, as well as difficulties in social domains.
