Becoming through Revolutionary Pedagogy: An Interview with Curry Malott and Derek R. Ford.

In this interview, Curry Malott and Derek R. Ford discuss their new book, Marx, Capital, and Education: Towards a Critical Pedagogy of Becoming. The interview begins with a general inquiry into their intellectual backgrounds as scholar-activists and, importantly, comrades. The authors then discuss the process of collaborating together on the book itself and its content. In writing the book, the authors were “particularly interested in the role of education in revolution” and, thus, the role of comradeship for resisting the reproduction of capitalist social relations. In this regard, the book is an intervention linking Marxist educational theory with critical pedagogy for a revolutionary critical pedagogy of becoming that reclaims the radical roots of critical pedagogy. The authors contextualize revolutionary critical pedagogy with examples from the Ferguson rebellion in the United States. Lastly, Malott and Ford share their current and future research projects.
First-Order Probabilistic Models for Information Extraction

Information extraction (IE) is the problem of constructing a knowledge base from a corpus of text documents. In this paper, we argue that ﬁrst-order probabilistic models (FOPMs) are a promising framework for IE, for two main reasons. First, FOPMs allow us to reason explicitly about en-tites that are mentioned in multiple documents, and compute the probability that two strings refer to the same entity — thus addressing the problem of coreference or record linkage in a principled way. Second, FOPMs allow us to resolve ambiguities in a text passage using information from the whole corpus, rather than disambiguating based on local cues alone and then trying to merge the results into a coherent knowledge base. This paper presents a comprehensive FOPM for a bibliographic database, and explains how the desired inference patterns emerge from the model.
Activity-dependent regulation of T-type calcium channels by submembrane calcium ions

Voltage-gated Ca2+ channels are involved in numerous physiological functions and various mechanisms finely tune their activity, including the Ca2+ ion itself. This is well exemplified by the Ca2+-dependent inactivation of L-type Ca2+ channels, whose alteration contributes to the dramatic disease Timothy Syndrome. For T-type Ca2+ channels, a long-held view is that they are not regulated by intracellular Ca2+. Here we challenge this notion by using dedicated electrophysiological protocols on both native and expressed T-type Ca2+ channels. We demonstrate that a rise in submembrane Ca2+ induces a large decrease in T-type current amplitude due to a hyperpolarizing shift in the steady-state inactivation. Activation of most representative Ca2+-permeable ionotropic receptors similarly regulate T-type current properties. Altogether, our data clearly establish that Ca2+ entry exerts a feedback control on T-type channel activity, by modulating the channel availability, a mechanism that critically links cellular properties of T-type Ca2+ channels to their physiological roles.

An empirical comparison among the effect of different supports in sequential robotic manipulation

Pick-and-place regrasp extends the manipulation capability of a robot by using a sequence of regrasps to accomplish tasks that are not possible using a single grasp due to constraints such as kinematics or collisions between the robot and the environment. Previous work on pick-and-place only leveraged static passive devices for intermediate placements, and thus is limited in the flexibility and robustness to reorient an object. In this paper, we extend the reorientation capability of a pick-and-place regrasp by adding an actively actuated gripper fixed in the working cell, and using it as the intermediate location for regrasping. In particular, our method automatically computes the stable placements of an object being hold in the gripper support, finds a rich set of force-closure grasps, performs k-means based grasp clustering, generates a graph of regrasp actions, and searches for the optimal regrasp sequence. To compare the regrasping performance with typical passive supports, we evaluate the success rate while performing tasks on various models. Experiments on reorientation tasks validate the benefit of using an actively actuated gripper for regrasp placement.
Quality of Parenting and Adolescent Attachment Security: A Twin Study to Explore the Impact of Genetic Factors

The overall focus of the thesis is the role of genetic and environmental influences in the relationship between quality of parenting and adolescent attachment security. Part one is a literature review exploring interactive antecedents of attachment security beyond infancy. The review includes 16 papers exploring the relationship between the quality of parentchild interactions and attachment security in children and adolescents, with security assessed using a representational measure of attachment, in order to establish which aspects of parenting are most strongly associated with attachment security. Part two of the thesis reports findings from a twin study designed to explore child-based genetic influences in quality of parenting and adolescent attachment security, using archived data from the Twins Early Development Study. Specifically, the study firstly aimed to examine the relative contribution of child genetic factors on quality of parenting, when parenting is assessed using observational methods. Secondly, the study examined whether common genes or common environments can account for the covariance between parenting quality and adolescent attachment security. Part three is a critical appraisal of the research process, which considers the conceptual issues and dilemmas involved in observational research and reflects on the implications of the study findings for future research and clinical practice.

Uncertainty modeling and control design of variable-geometry suspension

The paper proposes the modeling and control design of a variable-geometry suspension system. The goal of the modification of wheel camber is to track road trajectory and enhance the lateral stability of the vehicle. The purpose of the system is to assist the driver to perform various maneuvers by influencing the camber angles of the rear wheels. First a tyre model and a dynamical model of the suspension are described. Second, the uncertainties of the system, which are considered at the control design of a variable-geometry suspension are formalized. The control design is based on the robust H∞/μ method, which meets the performance specifications and guarantees robustness against model uncertainties.
Effects of insulin-like growth factor-I on glucose tolerance, insulin levels, and insulin secretion.

Insulin-like growth factor-I (IGF-I) and insulin interact with related receptors to lower plasma glucose and to exert mitogenic effects. Recombinant human IGF-I (rhIGF-I) was recently shown to decrease serum levels of insulin and C-peptide in fasted normal subjects without affecting plasma glucose levels. In this study we have investigated in six healthy volunteers the responses of glucose, insulin, and C-peptide levels to intravenous rhIGF-I infusions (7 and 14 micrograms/kg.h) during standard oral glucose tolerance tests (oGTT) and meal tolerance tests (MTT), respectively. Glucose tolerance remained unchanged during the rhIGF-I infusions in the face of lowered insulin and C-peptide levels. The decreased insulin/glucose-ratio presumably is caused by an enhanced tissue sensitivity to insulin. The lowered area under the insulin curve during oGTT and MTT as a result of the administration of rhIGF-I were related to the fasting insulin levels during saline infusion (oGTT: r = 0.825, P less than 0.05; MTT: r = 0.895, P less than 0.02). RhIGF-I, however, did not alter the ratio between C-peptide and insulin, suggesting that the metabolic clearance of endogenous insulin remained unchanged. In conclusion, rhIGF-I increased glucose disposal and directly suppressed insulin secretion. RhIGF-I probably increased insulin sensitivity as a result of decreased insulin levels and suppressed growth hormone secretion. RhIGF-I, therefore, may be therapeutically useful in insulin resistance of type 2 diabetes, obesity, and hyperlipidemia.
Simulation and analysis of a STBC-DSQPSK-CDMA scheme with image transferring experiments

Space-Time Code is one of the most practical techniques for a MIMO system. In case of other diversity techniques are not available (e.g., for a quasi-static fading channel), it is still a simple and efficient way to apply. Alamouti scheme is the earliest implementation of the Space-Time Code. It is easier to extend to multi-antenna case and further to perform transmitter diversity and receiver diversity as well. The decoding process of the scheme could be carried out with a linear complexity, so it is easier for the terminal to perform the decoding process within limited resources. An Alamouti scheme is integrated with a DS-QPSK-CDMA system and images are transferred through the simulation system with different SNR. It shows the simulation system works well, and the quality of image after transferring by the system is consistent with the BER performance simulation and analysis results of the simulation system. In addition, a typical MIMO simulation system usually suppose that the multiple antenna channels are synchronized by default, however, a different simulation result is given in this paper, in which the sub-streams are not synchronized. It shows synchronization of the parallel channels has great effect on the performance of a multiple antenna system.
SecFUN: Security framework for underwater acoustic sensor networks

In this paper we introduce SecFUN, a security framework for underwater acoustic sensor networks (UASNs). Despite the increasing interest on UASNs, solutions to secure protocols from the network layer up to the application layer are still overlooked. The aim of this work is therefore manyfold. We first discuss common threats and countermeasures for UASNs. Then, we select the most effective cryptographic primitives to build our security framework (SecFUN). We show that SecFUN is flexible and configurable with different features and security levels to satisfy UASN deployment security requirements. SecFUN provides data confidentiality, integrity, authentication and non-repudiation by exploiting as building blocks AES in the Galois Counter Mode (GCM) and short digital signature algorithms. As a proof of concept of the proposed approach, we extend the implementation of the Channel-Aware Routing Protocol (CARP) to support the proposed cryptographic primitives. Finally, we run a performance evaluation of our proposed secure version of CARP in terms of the overall energy consumption and latency, employing GCM and the state of the art in short digital signature schemes such as ZSS, BLS and Quartz. Results show that a flexible and full-fledged security solution tailored to meet the requirements of UASNs can be provided at reasonable costs.
Interaction of sedentary behaviour, sports participation and fitness with weight status in elementary school children

Abstract Even though the effect of single components contributing to weight gain in children have been addressed only limited research is available on the combined association of sports participation, physical fitness and time spent watching TV with body weight in children. Baseline data from 1594 children (809 male; 785 female), 7.1±0.6 years of age participating in a large school-based intervention in southern Germany was used. Height and weight was measured and body mass index (BMI) percentiles (BMIPCT) were determined accordingly. Sports participation and time spent watching TV was assessed via parent questionnaire while fitness was determined via a composite fitness test. Combined and single associations of sports participation, TV time and fitness with BMIPCT and weight status were assessed via ANCOVA as well as logistic regression analysis, controlling for age and sex. A significant interaction of TV time, sports participation and fitness on BMIPCT occurred, despite low correlations among the three components. Further, there was a combined association of sports participation and TV time on BMIPCT. TV time and fitness were also independently associated with BMIPCT. Similarly, only increased TV time and lower fitness were associated with a higher odds ratio for overweight/obesity. These results underline the complex interaction of TV time, sports participation and fitness with BMIPCT. In children, TV time and fitness have a stronger influence on BMIPCT compared to sports participation. Sports participation, however, may not reflect overall activity levels of children appropriately. More research is necessary to examine the complex interaction of various behaviours and fitness with BMIPCT.
The distinct functions of CENP-C and CENP-T/W in centromere propagation and function in Xenopus egg extracts

The centromere is the chromosomal region in which the kinetochore is assembled to orchestrate chromosome segregation. It is defined by the presence of a histone H3 variant called Centromere Protein A (CENP-A) or CenH3. Propagation of centromere identity entails deposition of new CENP-A upon exit from mitosis in vertebrate cells. A group of 16 proteins that co-immunoprecipitate with CENP-A, the Constitutive Centromere Associated Network or CCAN, contribute to kinetochore assembly and function. For most of them it is still unclear how and when they are recruited to centromeres and whether they have a role in CENP-A deposition. Taking advantage of the Xenopus egg cell-free system, we have addressed these issues for CCAN proteins CENP-C, CENP-T and CENP-W. CENP-C recruitment occurs as soon as sperm DNA, containing CENP-A, is added to the egg extract, and continues after de novo incorporation of CENP-A in early interphase. In contrast, centromeric recruitment of CENP-T occurs in late interphase and precedes that of CENP-W, which occurs in mitosis. Unlike CENP-C, CENP-T and CENP-W do not participate in CENP-A deposition. However, like CENP-C, they play a major role in kinetochore assembly. Depletion of CENP-C results in reduced amount of CENP-T at centromeres, an effect more prominent in mitosis than in interphase. In spite of this, kinetochores can still be assembled under this condition although the recruitment of Ndc80 and Mis12 is decreased. Our results support the existence of 2 pathways for kinetochore assembly directed by CENP-C and CENP-T/W, which can be reconstituted in Xenopus egg extracts.
Economic Integration and Location of Manufacturing : Evidence from Mercosur

Economic integration is likely to result in production structure changes in the participating countries via reallocation of resources across sectors and space. Over the past two decades, Argentina, Brazil, Paraguay, and Uruguay opened their economies by implementing unilateral trade libearlization measures and establishing a regional trade bloc, Mercosur. The question arises then whether and to what extent has trade liberalization affected the location of economic activities in these countries. This paper aims at answering the following questions: How specialized/diversified are the countries members of Mercosur? How concentrated/ dispersed are industries? What are the main determinants of manufacturing location? Did the establishment of Mercosur have an impact on location of economic activities? We analyse specialization and concentration patterns in Mercosur using manufacturing production data for the period 19711998. Our econometric analysis of determinants of manufacturing location defined by the distribution of country shares in each industry indicates that interactions between factor endowments and factor intensities as well as interactions between market potential and scale economies and market potential and intermediate inputs consumption are the main driving factors for manufacturing location patterns.
A comparative study of the actin-based motilities of the pathogenic bacteria Listeria monocytogenes, Shigella flexneri and Rickettsia conorii.

Listeria monocytogenes, Shigella flexneri, and Rickettsia conorii are three bacterial pathogens that are able to polymerize actin into 'comet tail' structures and move within the cytosol of infected cells. The actin-based motilities of L. monocytogenes and S. flexneri are known to require the bacterial proteins ActA and IcsA, respectively, and several mammalian cytoskeleton proteins including the Arp2/3 complex and VASP (vasodilator-stimulated phosphoprotein) for L. monocytogenes and vinculin and N-WASP (the neural Wiskott-Aldrich syndrome protein) for S. flexneri. In contrast, little is known about the motility of R. conorii. In the present study, we have analysed the actin-based motility of this bacterium in comparison to that of L. monocytogenes and S. flexneri. Rickettsia moved at least three times more slowly than Listeria and Shigella in both infected cells and Xenopus laevis egg extracts. Decoration of actin with the S1 subfragment of myosin in infected cells showed that the comet tails of Rickettsia have a structure strikingly different from those of L. monocytogenes or S. flexneri. In Listeria and Shigella tails, actin filaments form a branching network while Rickettsia tails display longer and not cross-linked actin filaments. Immunofluorescence studies revealed that the two host proteins, VASP and (&agr;)-actinin colocalized with actin in the tails of Rickettsia but neither the Arp2/3 complex which we detected in the Shigella actin tails, nor N-WASP, were detected in Rickettsia actin tails. Taken together, these results suggest that R. conorii may use a different mechanism of actin polymerization.
Complexity of chromatin folding is captured by the strings and binders switch model

Chromatin has a complex spatial organization in the cell nucleus that serves vital functional purposes. A variety of chromatin folding conformations has been detected by single-cell imaging and chromosome conformation capture-based approaches. However, a unified quantitative framework describing spatial chromatin organization is still lacking. Here, we explore the “strings and binders switch” model to explain the origin and variety of chromatin behaviors that coexist and dynamically change within living cells. This simple polymer model recapitulates the scaling properties of chromatin folding reported experimentally in different cellular systems, the fractal state of chromatin, the processes of domain formation, and looping out. Additionally, the strings and binders switch model reproduces the recently proposed “fractal–globule” model, but only as one of many possible transient conformations.
An application of Visual Computational Theory in spatial frequency domain: The simulation of dynamic radiated fringes

Visual Computational Theory that was founded by Marr plays an extraordinarily important role in Visual Science. There is still lot of research to do for this theory, such as building it in spatial frequency domain. Our research will be mainly on Visual Computational theory in spatial frequency domain and an application of the theory, which is the simulation of dynamic radiated fringes.
Use the Force: Evaluating Force-Sensitive Authentication for Mobile Devices

Modern, off-the-shelf smartphones provide a rich set of possible touchscreen interactions, but knowledge-based authentication schemes still rely on simple digit or character input. Previous studies examined the shortcomings of such schemes based on unlock patterns, PINs, and passcodes. In this paper, we propose to integrate pressure-sensitive touchscreen interactions into knowledge-based authentication schemes. By adding a (practically) invisible, pressuresensitive component, users can select stronger PINs that are harder to observe for a shoulder surfer. We conducted a within-subjects design lab study (n = 50) to compare our approach termed force-PINs with standard four-digit and six-digit PINs regarding their usability performance and a comprehensive security evaluation. In addition, we conducted a field study that demonstrated lower authentication overhead. Finally, we found that force-PINs let users select higher entropy PINs that are more resilient to shoulder surfing attacks with minimal impact on the usability performance.
Gyrus: A Framework for User-Intent Monitoring of Text-based Networked Applications

Traditional security systems have largely focused on attack detection. Unfortunately, accurately identifying the latest attack has proven to be a never-ending cycle. In this paper, we propose a way to break this cycle by ensuring that a system's behavior matches the user's intent. Since our approach is attack agnostic, it will scale better than traditional security systems. There are two key components to our approach. First, we capture the user's intent through their interactions with an application. Second, we verify that the resulting system output can be mapped back to the user's interactions. To demonstrate how this works we created Gyrus, a research prototype that observes user interactions for common tasks such as sending email, instant messaging, online social networking, and online financial services. Gyrus secures these applications from malicious behavior such as spam and wire fraud by allowing only outgoing traffic with content that matches the user's intent. To understand how Gyrus captures user intent, consider the case of a text- based application. In this case the user's input is displayed on the screen so the user can confirm that their input is correct. Gyrus builds on this concept by focusing on what is being displayed to the user instead of what the user has typed or clicked. We call this the "what you see is what you send (WYSIWYS)" policy. We implemented Gyrus under a standard virtualization environment, and our prototype system successfully stops malware from sending unintended content over the network. Our evaluation shows that Gyrus is very efficient and introduces no noticeable delay to a users' interaction with the protected applications.
Robust Multivariate Location and Dispersion

Robust estimators for multivariate location and dispersion should be √ n consistent and highly outlier resistant, but estimators that have been shown to have these properties are impractical to compute. This paper gives easily computed √ n consistent outlier resistant estimators that can be used for inference. Applications are numerous, including outlier detection and a diagnostic for whether the data distribution is elliptically contoured.
