Using the Psychological Concept of Compassion to Inform Pedagogic Strategies for Higher Education Seminars

This study used the university discussion-based seminar with the aim of exploring and improving students’ experiences of face-to-face group work in Higher Education. The purpose was to devise a pedagogic strategy to address the communicative barriers that extant research and literature suggests often arise between ethnically and/or internationally different student groups in universities. A critical examination of literature relevant to co-operative behaviours in groups was undertaken across disciplines. The result was the assembly and development of a theoretical basis for designing a pedagogy that attends explicitly to compassion in HE teaching, learning and assessment. Compassion is relevant to co-operative behaviours. It is recognised across disciplines and it is valued across cultures. It is defined as the noticing of distress or disadvantaging of others, and then taking action to reduce this. The compassion-focussed pedagogy was then applied in discussion-based seminars across different subjects in a UK university. The study adopted an action research approach, which was divided into two cycles. Cycle 1 was conducted amongst mainly white, local students in a Humanities department where (n=105) students were observed in their seminars, some of whom (n=14) participated in one-to-one interviews or focus groups. Cycle 2 was conducted amongst more diverse cohorts of students in the same HEI's Business department where (n=135) students were observed, some of whom (n=20) participated in one-to-one interviews or focus groups. In total (n=9) seminar tutors were observed and interviewed. Five sampling methods and seven data collection tools were combined to support the use of Template Analysis for comparative, thematic data analysis. Overall, most students made use of the compassion-focused pedagogy, adapting and developing it in seminar discussions to benefit the learning and social experiences of themselves and others. Data from three students helped explore why the pedagogy might not be suitable for all students. There was evidence of a positive impact on seminar academic outcomes in terms of assessment for critical thinking skills, particularly for BME students, although this result is offered cautiously and requires further research. The main indications from the study are that explicit work with the concept of compassion, including overt formal assessment of its use, can be unintrusive on subject material (a tutor concern), ethically appropriate, and beneficial to enhancing social and learning interconnectivity between students. Traditional/ standard categorisations of students as local or international in origin are also found to be extremely problematic and profoundly unhelpful in understanding and unlocking communicative barriers between students.
Resource allocation scheme for device-to-device communication for maximizing spatial reuse

Recently, device-to-device (D2D) communication in cellular networks has gained much attention for enabling a base station (BS) to offload traffic to direct D2D links and for facilitating new network services. In this paper, we propose a semi-distributed resource allocation scheme for the D2D communication where the BS allocates radio resources for cellular user links and D2D links in a centralized manner while the modulation and coding scheme (MCS) level and the transmission power of D2D links are distributively decided by the device of each D2D link. We first formulate a resource allocation problem of which the objective is to maximize the spatial reuse of radio resources by allowing the simultaneous transmission of D2D links on the same resources. To solve the problem, we present a suboptimal greedy algorithm. By simulation, we show that the cellular networks with the proposed scheme achieve a higher network throughput by maximizing the spatial reuse of radio resources.
Multi-Word Expression Identification Using Sentence Surface Features

Much NLP research on Multi-Word Expressions (MWEs) focuses on the discovery of new expressions, as opposed to the identification in texts of known expressions. However, MWE identification is not trivial because many expressions allow variation in form and differ in the range of variations they allow. We show that simple rule-based baselines do not perform identification satisfactorily, and present a supervised learning method for identification that uses sentence surface features based on expressions' canonical form. To evaluate the method, we have annotated 3350 sentences from the British National Corpus, containing potential uses of 24 verbal MWEs. The method achieves an F-score of 94.86%, compared with 80.70% for the leading rule-based baseline. Our method is easily applicable to any expression type. Experiments in previous research have been limited to the compositional/non-compositional distinction, while we also test on sentences in which the words comprising the MWE appear but not as an expression.
Design and evaluation of a head-mounted display for immersive 3D teleoperation of field robots

SUMMARY This paper describes and evaluates the use of a head-mounted display (HMD) for the teleoperation of a field robot. The HMD presents a pair of video streams to the operator (one to each eye) originating from a pair of stereo cameras located on the front of the robot, thus providing him/her with a sense of depth (stereopsis). A tracker on the HMD captures 3-DOF head orientation data which is then used for adjusting the camera orientation by moving the robot and/or the camera position accordingly, and rotating the displayed images to compensate for the operator's head rotation. This approach was implemented in a search and rescue robot (RAPOSA), and it was empirically validated in a series of short user studies. This evaluation involved four experiments covering two-dimensional perception, depth perception, scene perception, and performing a search and rescue task in a controlled scenario. The stereoscopic display and head tracking are shown to afford a number of performance benefits. However, one experiment also revealed that controlling robot orientation with yaw input from the head tracker negatively influenced task completion time. A possible explanation is a mismatch between the abilities of the robot and the human operator. This aside, the studies indicated that the use of an HMD to create a stereoscopic visualization of the camera feeds from a mobile robot enhanced the perception of cues in a static three-dimensional environment and also that such benefits transferred to simulated field scenarios in the form of enhanced task completion times.
Semantics of General References by a Hierarchy of Gödel Numberings

We demonstrate a semantic model of general references — that is, mutable memory cells that may contain values of any (staticallychecked) closed type, including other references. Our model is in terms of execution sequences on a von Neumann machine; thus, it can be used in a Proof-Carrying Code system where the skeptical consumer checks even the proofs of the typing rules. Our proof is machine-checked in the Twelf metalogic.
Naval Postgraduate School Monterey, California Transport Traffic Analysis for Abusive Infrastructure Characterization

We investigate a promising approach that identifies discriminating features of likely communications involving abusive hosts from per-packet TCP header and timing information. These features identify congestion, flow-control, and other low-level network and system characteristics indicative of an abusive network host. Our approach is IP address and content agnostic, and therefore privacy-preserving to permit wider deployment than previously possible. Importantly, the modeled characteristics are inherent to the poorly connected, under-provisioned, low-end, and overloaded hosts or links typical of abusive infrastructure making them difficult for an adversary to manipulate. In contrast to existing network-centric approaches reliant on flow-level records, fine-grained per-packet features yield superior performance with negligible processing impact. On real-world traces from accessing ∼40,000 Alexa and ∼30,000 known-abusive web sites, we achieve a classification accuracy of ∼94% with a 3% false positive rate using only transport features.
Twosome Coloring: Designing a Playful Coloring System on Dual-sided Transparent Surfaces

This paper introduces a coloring application for dual-sided transparent surfaces. It extends the traditional coloring experience with see-through display technology and dual-sided interaction techniques that enable a playful user experience. Twosome Coloring allows two users to interact with a see-through color picker and twosome interaction techniques on dual-sided transparent surfaces. We describe design concerns related to see-through technology, dual-sided interaction and application design, and present the results from a preliminary user study that indicates the benefit of see-through interface and twosome interactions.
LexFr: Adapting the LexIt Framework to Build a Corpus-based French Subcategorization Lexicon

This paper introduces LexFr, a corpus-based French lexical resource built by adapting the framework LexIt, originally developed to describe the combinatorial potential of Italian predicates. As in the original framework, the behavior of a group of target predicates is characterized by a series of syntactic (i.e., subcategorization frames) and semantic (i.e., selectional preferences) statistical information (a.k.a. distributional profiles) whose extraction process is mostly unsupervised. The first release of LexFr includes information for 2,493 verbs, 7,939 nouns and 2,628 adjectives. In these pages we describe the adaptation process and evaluated the final resource by comparing the information collected for 20 test verbs against the information available in a gold standard dictionary. In the best performing setting, we obtained 0.74 precision, 0.66 recall and 0.70 F-measure.
Supragastric Belching: Prevalence and Association With Gastroesophageal Reflux Disease and Esophageal Hypomotility

Background/Aims Supragastric belching (SGB) is a phenomenon during which air is sucked into the esophagus and then rapidly expelled through the mouth. Patients often complain of severely impaired quality of life. Our objective was to establish the prevalence of excessive SGB within a high-volume gastrointestinal physiology unit, and evaluate its association with symptoms, esophageal motility and gastresophageal reflux disease. Methods We established normal values for SGB by analyzing 24-hour pH-impedance in 40 healthy asymptomatic volunteers. We searched 2950 consecutive patient reports from our upper GI Physiology Unit (from 2010–2013) for SGB. Symptoms were recorded by a standardized questionnaire evaluating for reflux, dysphagia, and dyspepsia symptoms. We reviewed the predominant symptoms, 24-hour pH-impedance and high-resolution esophageal manometry results. Results Excessive SGB was defined as > 13 per 24 hours. We identified 100 patients with excessive SGB. Ninety-five percent of these patients suffered from typical reflux symptoms, 86% reported excessive belching, and 65% reported dysphagia. Forty-one percent of patients with excessive SGB had pathological acid reflux. Compared to the patients with normal acid exposure these patients trended towards a higher number of SGB episodes. Forty-four percent of patients had esophageal hypomotility. Patients with hypomotility had a significantly higher frequency of SGB compared to those with normal motility (118.3 ± 106.1 vs 80.6 ± 75.7, P = 0.020). Conclusions Increased belching is rarely a symptom in isolation. Pathological acid exposure and hypomotility are associated with more SGB frequency. Whether SGB is a disordered response to other esophageal symptoms or their cause is unclear.
Regulated Proteolytic Processing of Reelin through Interplay of Tissue Plasminogen Activator (tPA), ADAMTS-4, ADAMTS-5, and Their Modulators

The extracellular signaling protein Reelin, indispensable for proper neuronal migration and cortical layering during development, is also expressed in the adult brain where it modulates synaptic functions. It has been shown that proteolytic processing of Reelin decreases its signaling activity and promotes Reelin aggregation in vitro, and that proteolytic processing is affected in various neurological disorders, including Alzheimer's disease (AD). However, neither the pathophysiological significance of dysregulated Reelin cleavage, nor the involved proteases and their modulators are known. Here we identified the serine protease tissue plasminogen activator (tPA) and two matrix metalloproteinases, ADAMTS-4 and ADAMTS-5, as Reelin cleaving enzymes. Moreover, we assessed the influence of several endogenous protease inhibitors, including tissue inhibitors of metalloproteinases (TIMPs), α-2-Macroglobulin, and multiple serpins, as well as matrix metalloproteinase 9 (MMP-9) on Reelin cleavage, and described their complex interplay in the regulation of this process. Finally, we could demonstrate that in the murine hippocampus, the expression levels and localization of Reelin proteases largely overlap with that of Reelin. While this pattern remained stable during normal aging, changes in their protein levels coincided with accelerated Reelin aggregation in a mouse model of AD.
The STONE Transform: Multi-Resolution Image Enhancement and Real-Time Compressive Video

Compressed sensing enables the reconstruction of high-resolution signals from under-sampled data. While compressive methods simplify data acquisition, they require the solution of difficult recovery problems to make use of the resulting measurements. This article presents a new sensing framework that combines the advantages of both conventional and compressive sensing. Using the proposed \stone transform, measurements can be reconstructed instantly at Nyquist rates at any power-of-two resolution. The same data can then be "enhanced" to higher resolutions using compressive methods that leverage sparsity to "beat" the Nyquist limit. The availability of a fast direct reconstruction enables compressive measurements to be processed on small embedded devices. We demonstrate this by constructing a real-time compressive video camera.
Reranking with Multiple Features for Better Transliteration

Effective transliteration of proper names via grapheme conversion needs to find transliteration patterns in training data, and then generate optimized candidates for testing samples accordingly. However, the top-1 accuracy for the generated candidates cannot be good if the right one is not ranked at the top. To tackle this issue, we propose to rerank the output candidates for a better order using the averaged perceptron with multiple features. This paper describes our recent work in this direction for our participation in NEWS2010 transliteration evaluation. The official results confirm its effectiveness in English-Chinese bidirectional transliteration.
Spectral Processing of Tangential Vector Fields

We propose a framework for the spectral processing of tangential vector fields on surfaces. The basis is a Fourier‐type representation of tangential vector fields that associates frequencies with tangential vector fields. To implement the representation for piecewise constant tangential vector fields on triangle meshes, we introduce a discrete Hodge–Laplace operator that fits conceptually to the prominent cotan discretization of the Laplace–Beltrami operator. Based on the Fourier representation, we introduce schemes for spectral analysis, filtering and compression of tangential vector fields. Moreover, we introduce a spline‐type editor for modelling of tangential vector fields with interpolation constraints for the field itself and its divergence and curl. Using the spectral representation, we propose a numerical scheme that allows for real‐time modelling of tangential vector fields.
A Novel Method for Collaborative Spam E- Mails

With the increasing popularity of electronic mail (E-mail), several people and companies found it an easy way to distribute a massive amount of unsolicited messages to a tremendous number of users at a very low cost. These unwanted bulk messages or junk emails are called spam E- mails. The majority of spam mails that has been reported recently are unsolicited commercials promoting services and products including sexual enhancers, cheap drugs and herbal supplements, health insurance, travel tickets, hotel reservations, and software products. Spam E- mails has become an epidemic problem that can negatively affect the usability of electronic mail as a communication means. Besides wasting users time and effort to scan and delete these spam messages received; it consumes network bandwidth and storage space, slows down e-mail servers, and provides a medium to distribute harmful and/or offensive content. This paper presents a novel method for collaborative spam messages.
An old lineage of Cyphophthalmi (Opiliones) discovered on Mindanao highlights the need for biogeographical research in the Philippines

Abstract The arachnid order Opiliones, and the suborder Cyphophthalmi in particular, have recently been used to test biogeographical patterns in Southeast Asia due to their ancient age and extremely low vagility. Here we report the first Cyphophthalmi—two juveniles—known from Mindanao in the southern Philippine Archipelago, and we place them in a molecular phylogeny to test biogeographical hypotheses for their colonization of that island. Five molecular markers were sequenced from one specimen, three from the other, and these sequences were added to a previously completed phylogenetic analysis. The specimens were recovered as members of a clade found almost exclusively on Borneo. Their deep placement within this clade suggests a very old origin and colonization that perhaps involved the mysterious landmass now underlying Mindanao's Zamboanga Peninsula. This species prompts new questions about the abilities of Southeast Asian Cyphophthalmi (Stylocellidae) to disperse and colonize, and it emphasizes how much remains to be understood about the geological history of the Philippines.
Bending and orientational characteristics of long period gratings written in D-shaped optical fiber [directional bend sensors]

Long period gratings (LPGs) were written into a D-shaped single-mode fiber. These LPGs were subjected to a range of curvatures, and it was found that as curvature increased, there was increasingly strong coupling to certain higher order cladding modes without the usual splitting of the LPGs stopbands. A bend-induced stopband yielded a spectral sensitivity of 12.55 nm/spl middot/m for curvature and 2.2/spl times/10/sup -2/ nm/spl deg/C/sup -1/ for temperature. It was also found that the wavelength separation between adjacent bend-induced stopbands varied linearly as a function of curvature. Blue and red wavelength shifts of the stopbands were observed as the sensor was rotated around a fixed axis for a given curvature; thus, in principle, this sensor could be used to obtain bending and orientational information. The behavior of the stopbands was successfully modeled using a finite element approach.
Lentiviral and Moloney Retroviral Expression of Green Fluorescent Protein in Somatotrophs In Vivo

Previous studies have shown that the locus control region (LCR) and the promoter of the growth hormone (GH) gene can control the expression of GH. Therefore, lenti- and retro-viral vectors with these elements might be useful to monitor the activation of the GH gene and the development of newborn somatotrophs. To test this, we first constructed a lentiviral vector, which expresses green fluorescent protein (GFP) under the control of these elements, and injected them into rat pituitaries in situ and in vivo. The lentiviral vector expressed GFP specifically in the anterior lobe, and nearly all GFP-positive cells were anti-GH immunoreactive. The GFP expression was upregulated by the administration of growth hormone releasing hormone and an IGF-1 receptor blocker. Furthermore, the social isolation stress, which was shown to decrease the GH secretion, decreased the GFP expression. Second, we injected the retroviral vector into neonatal rat pituitaries in vivo. At 30 days postinjection (DPI), almost all GFP-positive cells were anti-GH positive and anti-prolactin negative as the lentiviral expression. However, GFP was transiently expressed by developing lactotrophs at 8 and 16 DPI, suggesting that our vector lacks an element(s) which suppresses the expression. Meanwhile, the retrovirally labeled cells tended to cluster with the cells of same type. An analysis of cell numbers in each cluster revealed some features of cell proliferation. These viral vectors are shown to be useful tools to monitor the activation of the GH gene and the development of somatotrophs.
Ultrasound-guided corticosteroid injections for treatment of greater trochanteric pain syndrome: greater trochanter bursa versus subgluteus medius bursa.

OBJECTIVE The purpose of this study was to evaluate the effectiveness of corticosteroid injections into the greater trochanteric bursa as opposed to the subgluteus medius bursa in patients with greater trochanteric pain syndrome. MATERIALS AND METHODS We retrospectively reviewed 183 injections (149 performed in women, 34 performed in men; age range 23-90 years; median, 53 years) performed for treatment of greater trochanteric pain syndrome. A 10-cm visual analog scale survey was used to assess pain level before the procedure and 14 days after the procedure. A 3-mL corticosteroid solution was injected into either the greater trochanteric bursa or the subgluteus medius bursa under direct ultrasound guidance. Procedure images were retrospectively reviewed to determine the site of injection. Diagnostic images obtained at the time of the procedure were also reviewed for findings of tendinopathy, bursitis, and enthesopathy. Statistical analysis of differences in pain reduction was performed, as was analysis for association between pain relief and demographic variables of age, sex, previous injections, and ultrasound findings. RESULTS Sixty-five injections met the inclusion criteria; 56 performed in women and nine performed in men (age range, 30-82 years; median, 53 years). Forty-one injections were into the greater trochanteric bursa and 24 into the subgluteus medius bursa. There was a statistically significant difference in pain reduction between greater trochanteric bursa and subgluteus medius bursa injections with a median pain reduction of 3 as opposed to 0 (p < 0.01). There was no statistically significant association between pain relief and demographic variables or ultrasound findings. CONCLUSION Corticosteroid injections into the greater trochanteric bursa may be more effective than injections into the subgluteus medius bursa for treatment of greater trochanteric pain syndrome.
