What Makes an Open Education Program Sustainable? The Case of Connexions

This paper explores the benefits of two innovations to OpenCourseWare: course production by fieldspecific graduate students and workshops for advanced undergraduates’ translation of OCW courses. Both seek to enhance the culture of teaching, not only among the faculty, but also among graduate and undergraduate students as future faculty. At the Spring 2006 OpenCourseWare Consortium Meeting in Kyoto, our Sustainability Work Group identified the embedding of open sharing in academic practice as an important consortium goal. The Notre Dame OpenCourseWare Pilot Project, just completing its first year with the launch of an eight-course site, has been designed with an eye to fostering just such an ethos of openness. Two structural innovations Notre Dame is introducing to the OpenCourseWare model show particular promise in this regard, aiming to influence the culture of teaching among the graduate and undergraduate students we will be sending out to teach coming generations. The first innovation, put into practice this past summer, is our use of graduate students as course production assistants. The second, coming into practice even as we speak, is the design of translation workshops wherein teams of advanced undergraduates will translate courses from Notre Dame OCW into languages such as Spanish, Portuguese, French, German, Russian, Chinese and Arabic. Together, these two innovations seek to engage our students in active reflection upon rather than passive reception of the practice of teaching. Such reflection, conducted in an environment focused upon open sharing, brings the student to a higher awareness of how integral that sharing is to a productive teaching environment. To begin with, let me note that Notre Dame’s OCW project is housed within our Kaneb Center for Teaching and Learning. That placement is more than merely circumstantial. It keeps our attention focused on OCW’s potential to transform the culture of teaching at Notre Dame. Because much of our work in the Kaneb Center addresses the needs of graduate students as novice instructors, we naturally looked to graduate students when we needed course production assistants. In training and working with these graduate students, we became even further aware of the opportunities OCW affords us for addressing issues surrounding the ways we choose to present knowledge. Because much of our work in the Kaneb Center addresses the quality of student learning, we naturally looked to the effect of translation projects on the fostering of undergraduate foreign language study. In developing translation workshops, we are becoming even further aware of the opportunities OCW affords us for alerting our students to global needs for access to knowledge. We might have realized these opportunities under other circumstances, but our collaboration with colleagues
Cognitive assessment of voices: further developments in understanding the emotional impact of voices.

OBJECTIVES This study examines cognitive behavioural assessment of auditory hallucinations ('voices') in people with psychoses. It aims to compare findings with previous work and validate the Assessment of Voices Schedule (Chadwick & Birchwood, 1994). Data were collected on appraisals of voices in relation to the self. It was hypothesized that self-appraisals may be a further factor in understanding the emotional impact of voices. DESIGN A replication study where data were collected from a new sample of participants and compared with a previous independent sample. METHOD Voices of 30 patients with a diagnosis of schizophrenia were assessed using a semi-structured interview and questionnaires. Thought-chaining was used to assess appraisals of the voice in relation to the self. RESULTS Compared to the previous study, current participants were significantly less likely to believe in the omnipotence of their voices, to view their voices as omniscient and to have a positive affective response to benevolent voices. Similar numbers in this study construed their voices as malevolent, but fewer participants in this sample had benevolent voices. There were no significant differences between samples in behavioural responses to voices or in the affective responses to malevolent voices. The Assessment of Voices Schedule was found to have generally good test-retest and inter-rater reliability. Extremely negative self-appraisals were common, as were negative affective responses to the voice experience and low self-esteem. CONCLUSION The implications of these findings for both cognitive behavioural models and therapy are discussed.
A Transfer Learning Based Boosting Model for Emotion Analysis

Emotion Analysis determines the emotion of a text. Supervised Machine learning algorithms are effective for Emotion Analysis, but they need a lot of labelled data. It is a labor-intensive process and often needs instructions of experts to annotate data. In this paper, we propose a transfer learning approach for emotion analysis based on Adaboost(EATAdaBoost) by adapting the knowledge learned from labelled source data to the target domain which has none or few labelled data. We try to establish connections between source instances and target domain. Word2vec semantic similarities between source instances and common non-domain-specific emotional words which occur frequently in both domains are used as a bridge. If the similarity is bigger than a threshold, we think the source instance is useful for learning target task. In addition, we conduct extensive experiments and the results show that our algorithm is superior to baselines.

An Efficient Noma V2X Communication Scheme in the Internet of Vehicles

This paper proposes a new graph-based practical encoding and joint belief propagation (BP) decoding techniques for two-vehicle communicating simultaneously with another vehicle or a roadside unit. The proposed scheme achieves any rate pair close to the capacity region without using time sharing. While at the encoders, the corresponding parity check matrices are randomly built from a half-rate matrix, the joint BP decoder employs the associated Tanner graphs of the parity check matrices to iteratively recover the erasures in the received combined messages. Specifically, the joint decoder performs two steps in each decoding iteration: 1) simultaneously and independently runs the BP decoding process at each constituent sub- graph to recover some of the common erasures, 2) update the other sub-graph with newly recovered erasures and vice versa. When the number of erasures in the received message is less than or equal to the number of parity check constraints, the decoder may successfully decode both messages, otherwise the decoder declares decoding failure. Furthermore, the probability of decoding failure and the outage capacity are computed. Additionally, it is shown how the erasure probability evolves with the number of decoding iterations and the maximum tolerable loss. Simulations show that any rate pair close to the capacity boundary is achievable without using time sharing.
Comprehensive Relationship Between Carrier-Based PWM and Space Vector PWM in a Five-Phase VSI

Multiphase machines are nowadays considered for high-power variable-speed drive applications due to numerous advantages that they offer when compared to their three-phase counterparts. Multiphase voltage source inverters are invariably used to provide multiphase variable voltage and variable frequency supply with appropriate pulsewidth modulation (PWM) control. Carrier-based PWM and space vector PWM (SVPWM) are the most common options. This paper is aimed at providing a comprehensive relationship between carrier-based PWM and SVPWM techniques. The relationship is determined in terms of modulation signals and space vectors, modulation signals and space vector sectors, and switching pattern of space vector and type of carrier. Distribution of zero vector is discussed, leading to different types of modulation schemes. The practical implementation issues of carrier-based PWM and SVPWM are discussed. Simulation results and their experimental validation are provided to support the analytical findings.
Linewidth effect and phase control in Ni fully silicided gates

The scalability of Ni fully silicided (FUSI) gate processes to short gate lengths was studied for NiSi, Ni<sub>2</sub>Si, and Ni<sub>31 </sub>Si<sub>12</sub>. It is shown that the control of the deposited Ni-to-Si ratio is not effective for phase and V<sub>t</sub> control at short gate lengths. A transition to Ni-richer phases at short gate lengths was found for nonoptimized NiSi and Ni<sub>2</sub>Si processes with excessive thermal budgets, resulting in significant V<sub>t</sub> shifts for devices on HfSiON consistent with the difference in work function among the Ni silicide phases. Linewidth-independent phase control with smooth V<sub>t</sub> rolloff characteristics was demonstrated for NiSi, Ni<sub>2</sub>Si, and Ni<sub>31</sub>Si<sub>12 </sub> FUSI gates by controlling the Ni-to-Si reacted ratio through optimization of the thermal budget of silicidation (prior to selective Ni removal). Phase characterization over a wide temperature range indicated that the process windows for scalable NiSi and Ni<sub>2</sub>Si are less than or equal to 25 degC, whereas a single-phase Ni<sub>31</sub>Si<sub>12</sub> is obtained over an ~200degC temperature range
Redistribution of activated pp60c-src to integrin-dependent cytoskeletal complexes in thrombin-stimulated platelets

Thrombin stimulation of platelets induces a transient increase in the specific activity of pp60c-src followed by a redistribution of pp60c-src to the Triton X-100-insoluble, cytoskeleton-rich fraction. Concomitant with the observed increase in pp60c-src activity was a rapid dephosphorylation of tyrosine 527 in 10 to 15% of pp60c-src molecules. In addition, we found that pp60c-src from the Triton-insoluble fraction was phosphorylated on tyrosine 416, the autophosphorylation site which is phosphorylated in activated oncogenic variants of pp60src. Furthermore, in platelets from patients with Glanzmann's thrombasthenia (which are deficient in the integrin receptor GPIIb-IIIa), pp60c-src was not translocated to the Triton-insoluble fraction, and there was a sustained increase in pp60c-src activity following thrombin treatment. These results suggest that pp60c-src is rapidly activated in thrombin-stimulated platelets, potentially by a protein tyrosine phosphatase, before it translocates to a cytoskeletal fraction, where many of its potential substrates are found. The evidence that the cytoskeletal association of pp60c-src is dependent upon engagement of the integrin receptor GPIIb-IIIa suggests that integrin-cytoskeletal complexes may serve to compartmentalize and anchor activated enzymes involved in signal transduction.
Zero-IF receivers for phased array radars

This paper considers the suitability of zero-IF receivers for inclusion into the transmit/receive (T/R) modules in modern phased array radars. The main performance measures are the overall system dynamic range and tuning range. The achievable dynamic range is estimated based on currently available components and compared against the results of a prototype system. The overall results indicate that a dynamic range of more than 60 dB is achievable in a 50 MHz bandwidth.
Carbon nanotube/silica composites obtained by sol–gel and high-pressure techniques

The successful incorporation of functionalized single-walled carbon nanotubes (f-SWCNTs) into a silica matrix prepared by the sol–gel method is reported herein. SWCNTs produced through catalytic chemical-vapor deposition (CCVD) have been purified and functionalized with sulfuric, nitric and hydrochloric acids to ensure a good dispersion in an aqueous solution. The nanotube composites are prepared using three concentrations of f-SWCNTs (0.025, 0.050 and 0.075 wt%.) in a silica matrix, resulting in translucent monoliths after gelation. Dense, crack-free and hard compacts are obtained by high-pressure processing at 7.7 GPa and room temperature. Compared to the pure silica compact, compacts containing 0.025 and 0.050 wt% f-SWCNTs show an increased toughness of about 54% and 69%, respectively. The influence of f-SWCNTs on some microstructural aspects of the silica matrix has been studied using nitrogen adsorption/desorption isotherms. Raman spectroscopy has been applied to analyze the effect of the silica matrix and high-pressure compaction on the f-SWCNTs incorporated into the silica matrix. These measurements showed that f-SWCNTs remained in the silica matrix under pressure, suggesting an important interaction with the matrix.
Macrophage migration inhibitory factor‐knockout mice are long lived and respond to caloric restriction

Macrophage migration inhibitory factor (MIF) affects inflammation, glucose homeostasis, and cellular proliferation in mammals. Previously, we found that MIF was significantly elevated in multiple long‐lived mouse models, including calorie restriction (CR), which led us to hypothesize that MIF might be important in the control of mammalian life span and be necessary for the life‐extending effects of CR. To test this hypothesis, we examined the life span of mice with a targeted deletion of the Mif gene on a segregating B6 × 129/Sv background (MIF‐KO) under ad libitum (AL) feeding and CR conditions. Control mice were generated by mating C57BL/6J females with 129/SvJ males to make an F1 hybrid, and crossing F1 males to F1 females to produce segregating F2 mice homozygous for the normal MIF allele. Not only did MIF‐KO mice show a life span extension in response to CR, they were, unexpectedly, longer lived than controls under standard AL conditions. MIF‐KO mice were significantly protected against lethal hemangiosarcoma, but more likely than controls to die of disseminated amyloid, an age‐related inflammatory syndrome. Overall, these data refute the suggestion that MIF is required for the CR effect on life span, but raise the possibility that MIF may limit life span in normal mice. —Harper, J. M. , Wilkinson, J.

Exchange rate prediction : a wavelet-neural approach

The paper deals with the use of artificial neural networks (ANN) for predictions of economic time series. First, we revise the basic existing ANN architectures for time series forecasting and describe their application on CZK/EUR exchange rate prediction. Next, we introduce a hybrid version of the ANN that builds upon the same network strategy but tries to enhance the prediction accuracy by first decomposing the signal into individual frequency bands and then training the perceptron parameters on each frequency band separately. The time-frequency signal analysis is obtained using discrete wavelet transform. Different signal segments in various levels of decomposition are reconstructed separately. The resulting signals (in time domain again) are samples for ANNs as above. Finally, we compare the accuracy of the hybrid approach to that of the traditional ANN setting for the case of CZK/EUR exchange rate data.
Statistical Power and Effect Sizes of Clinical Neuropsychology Research

Cohen, in a now classic paper on statistical power, reviewed articles in the 1960 issue of one psychology journal and determined that the majority of studies had less than a 5050 chance of detecting an effect that truly exists in the population, and thus of obtaining statistically significant results. Such low statistical power, Cohen concluded, was largely due to inadequate sample sizes. Subsequent reviews of research published in other experimental psychology journals found similar results. We provide a statistical power analysis of clinical neuropsychological research by reviewing a representative sample of 66 articles from the Journal of Clinical and Experimental Neuropsychology, the Journal of the International Neuropsychology Society, and Neuropsychology. The results show inadequate power, similar to that for experimental research, when Cohens criterion for effect size is used. However, the results are encouraging in also showing that the field of clinical neuropsychology deals with larger effect sizes than are usually observed in experimental psychology and that the reviewed clinical neuropsychology research does have adequate power to detect these larger effect sizes. This review also reveals a prevailing failure to heed Cohens recommendations that researchers should routinely report a priori power analyses, effect sizes and confidence intervals, and conduct fewer statistical tests.
Inward Remodeling Follows Chronic Vasoconstriction in Isolated Resistance Arteries

The hypothesis was tested that chronic vasoconstriction is followed by a structural reduction in lumen diameter, measured at full dilation. An in vitro model of pressurized rat skeletal muscle arterioles was used. During a 3-day experimental period, constriction of active vessels was achieved with fetal calf serum or endothelin-1 (ET-1). Maximal dilation revealed inward remodeling from 179 ± 6.5 µm lumen diameter on day 0 to 151 ± 6.3 µm on day 3 at 75 mm Hg in vessels incubated with serum (n = 8). Similarly, ET-1 induced inward remodeling from 182 ± 5.2 to 164 ± 3.7 µm (n = 6). When constriction during organoid culture was inhibited with papaverin or verapamil, inward remodeling was fully prevented: 184 ± 6.3 to 184 ± 5.8 µm for papaverin (n = 6) and 174 ± 5.5 to 177 ± 7.4 µm for verapamil (n = 6). A chronic reduction in diameter without tone was achieved in vessels that were kept at a low pressure (2–5 mm Hg; n = 6). Here, no remodeling was found, thereby ruling out that a chronic reduction in diameter alone is sufficient for inward remodeling. These data show that a persistent active reduction in lumen diameter is followed by inward remodeling of arterioles.
On microprocessor error behavior modeling

A microprocessor error behavior function (EBF) is introduced, mapping faults into errors on the functional level. The errors are obtained using a functional model of the processor. By applying the EBF to a fault and instruction distribution, it is possible to obtain the corresponding error distribution. A case study is described, in which (i) the EBFs for simulated bit-flip and pin-level faults are designed and used to compare the bit-flip and pin-level fault models, and (ii) the obtained error distribution for the bit-flip faults is used in an error injection experiment on the functional level to emulate these faults. For the processor used in the case study, it was found that only 9-12% of the bit-flip faults could be emulated using pin-level faults, while a tentative evaluation of the possibility to emulate bit-flip faults with software-implemented fault injection showed that 98-99% could be emulated. Finally, the results of the emulated bit-flip errors corresponded well to the real results obtained using bit-flip faults, thus indicating that the injected errors are good approximations of the faults. <<ETX>>
Microbial community structure in a silty clay loam soil after fumigation with three broad spectrum fungicides

The short-term effect of three broad spectrum fungicides on microbial activity, microbial biomass, soil ergosterol content, and phospholipid fatty acid (PLFA) profiles was studied. A silty clay loam soil was treated separately with captan, chlorothalonil and carbendazim at three different dosages of each fungicide. Chlorothalonil and carbendazim significantly altered soil microbial activity. However, changes in soil microbial biomass were only observed in soil treated with higher dosages of these fungicides. All dosages of fungicides significantly decreased fungal biomass as estimated by soil ergosterol content. PLFA analysis indicated that there was a shift in PLFA pattern. Higher dosages of all three fungicides decreased a straight-chain PLFA 22:0. In addition, soil treated with carbendazim increased cyclopropyl fatty acids. Compared to untreated soil, higher dosages of both captan and chlorothalonil affected PLFA 10Me 16:0, indicating that these fungicides can reduce actinomycetes population. Finally, our results suggest that application of both captan and chlorothalonil decreased Gram-positive to Gram-negative ratio.
Use of N-Acetyl Cysteine for the Treatment of Parenteral Nutrition–induced Liver Disease in Children Receiving Home Parenteral Nutrition

The use of long-term parenteral nutrition (PN) in children with significant gut failure has been associated with progressive cholestatic liver disease (1–4). Progression to liver cirrhosis and end-stage liver disease are well-known consequences of long-term dependence on PN. The etiology of liver disease related to PN administration seems to be multifactorial (1–3). There is evidence linking the macronutrient and micronutrient content of PN solutions to the onset and severity of PN-induced liver cholestasis (4). Recent studies in animal models, in particular, have demonstrated an association between the onset of cholestatic liver disease and intravenous (IV) methionine (MET) intake (4–6). Most commercial PN solutions have relatively higher amounts of MET and little or no cysteine (CYS) because of the instability of CYS in solution (7). Inasmuch as CYS is an important precursor of glutathione (GSH), it was hypothesized that provision of parenteral CYS could potentially counteract the oxidative stress that occurs in liver cholestasis (8). Recently, our group showed that Nacetyl cysteine (NAC) can be used as a source of CYS in PN solutions in piglets (9). We supplemented 2 infants and 1 child with PN-induced liver disease who were receiving PN at home with IV NAC as an adjunctive therapy to minimize further liver damage induced by PN.
In-vivo quantitative permeability assessment of the focused-ultrasound-induced blood-brain barrier opening using dynamic contrast-enhanced MRI

Pharmacokinetic modeling with dynamic contrast-enhanced MRI (DCE-MRI) has been established as an in vivo technique that estimates the permeability of the vessels. In this study, the most reliable model for permeability assessment of the focused ultrasound (FUS)-induced BBB opening was determined using DCE-MRI. Six mice were sonicated on the right hippocampal region using FUS at the peak-rarefactional acoustic pressure of 0.30 MPa, after intravenous injection of lipid-shelled microbubbles (4–5 μm in diameter). The general kinetic model (GKM) and the reference region model (RRM) were applied on the dynamic MR images to estimate the K<inf>trans</inf> values. The GKM-derived K<inf>trans</inf> for a specific volume of interest was found to be 0.02 ± 0.0123 min<sup>−1</sup>, while RRM yielded statistically insignificantly higher values, 0.03 ± 0.0167 min<sup>−1</sup>. Both GKM and RRM exhibited significantly low K<inf>trans</inf> values in the control region (0 and 8.5 ± 12×10<sup>−4</sup> min<sup>−1</sup> respectively). The two models showed excellent correlation (R<sup>2</sup> =0.97), verifying the consistency of the permeability measurements. However, the poor time-concentration curves of RRM suggest that GKM is more suitable for permeability estimation. In conclusion, GKM was found to be the optimal model for the permeability assessment of the FUS-induced BBB opening and the associated drug delivery efficacy.
Low complexity CMOS MIN circuit for low voltage applications
