Targeted muscle reinnervation for real-time myoelectric control of multifunction artificial arms.

CONTEXT Improving the function of prosthetic arms remains a challenge, because access to the neural-control information for the arm is lost during amputation. A surgical technique called targeted muscle reinnervation (TMR) transfers residual arm nerves to alternative muscle sites. After reinnervation, these target muscles produce electromyogram (EMG) signals on the surface of the skin that can be measured and used to control prosthetic arms. OBJECTIVE To assess the performance of patients with upper-limb amputation who had undergone TMR surgery, using a pattern-recognition algorithm to decode EMG signals and control prosthetic-arm motions. DESIGN, SETTING, AND PARTICIPANTS Study conducted between January 2007 and January 2008 at the Rehabilitation Institute of Chicago among 5 patients with shoulder-disarticulation or transhumeral amputations who underwent TMR surgery between February 2002 and October 2006 and 5 control participants without amputation. Surface EMG signals were recorded from all participants and decoded using a pattern-recognition algorithm. The decoding program controlled the movement of a virtual prosthetic arm. All participants were instructed to perform various arm movements, and their abilities to control the virtual prosthetic arm were measured. In addition, TMR patients used the same control system to operate advanced arm prosthesis prototypes. MAIN OUTCOME MEASURE Performance metrics measured during virtual arm movements included motion selection time, motion completion time, and motion completion ("success") rate. RESULTS The TMR patients were able to repeatedly perform 10 different elbow, wrist, and hand motions with the virtual prosthetic arm. For these patients, the mean motion selection and motion completion times for elbow and wrist movements were 0.22 seconds (SD, 0.06) and 1.29 seconds (SD, 0.15), respectively. These times were 0.06 seconds and 0.21 seconds longer than the mean times for control participants. For TMR patients, the mean motion selection and motion completion times for hand-grasp patterns were 0.38 seconds (SD, 0.12) and 1.54 seconds (SD, 0.27), respectively. These patients successfully completed a mean of 96.3% (SD, 3.8) of elbow and wrist movements and 86.9% (SD, 13.9) of hand movements within 5 seconds, compared with 100% (SD, 0) and 96.7% (SD, 4.7) completed by controls. Three of the patients were able to demonstrate the use of this control system in advanced prostheses, including motorized shoulders, elbows, wrists, and hands. CONCLUSION These results suggest that reinnervated muscles can produce sufficient EMG information for real-time control of advanced artificial arms.
A study of work satisfaction, burnout and other work-related variables among hungarian educators

The main goal of the present study was to investigate, based on the Job Demands–Resources Model, a set of work-related variables as possible correlates (either as job demands or resources) of work satisfaction in a sample of Hungarian educators (N = 2,068, aged between 23–74 years, mean = 48.1 and S.D. = 8.9; 83% females). Results report that in this sample of Hungarian educators, their work satisfaction is closely related to the presence of burnout (particularly emotional exhaustion) and it is also influenced by role conflicts and role ambiguity in their workplace; whereas work-family conflict and work time demands do not play a role. On the other hand, educators’ work satisfaction may be protected by certain job resources such as satisfaction with professional prestige, work social support and work involvement. Satisfaction with salary and work policy was not significant. Findings suggest that interventions at both individual and organisational level should be necessary, e.g. learning effective coping techniques to prevent burnout and increase work satisfaction well before the start of an educator’s career. The organisational interventions should strengthen job resources and eliminate/decrease job demands.
Acquirers’ prior related knowledge and post-acquisition integration: Evidences from four Chinese firms

Purpose – This paper examines the role of acquirers’ prior related knowledge in the post-acquisition integration process. The purpose of this paper is to identify what constitutes the key prior related knowledge that can contribute to the reverse knowledge transfer following Chinese firms’ outward mergers and acquisitions (M&As) to Europe, and explain how prior related knowledge affects such transfer of knowledge. Design/methodology/approach – The authors employ a multiple case study approach. Semi-structured interviews were conducted from February 2012 to June 2013 with 24 managers. Findings – The authors find that, in addition to knowledge about the target, prior international business experience, R&D capability, and industrial capabilities are key components of acquirers’ prior related knowledge that can contribute to the success of M&A integration and post-acquisition reverse knowledge transfer. Indeed, Chinese acquirers’ prior related knowledge can influence the reverse knowledge transfer from acquired firms to acquirers by directly improving acquirers’ absorptive capacity and building a harmonious organisational climate to facilitate such transfer. Originality/value – This paper contributes to the absorptive capacity and the cross-border M&A literature. It extends the current knowledge on the key components of an acquirer’s prior related knowledge in the outward M&A by Chinese firms. It also uncovers how post-acquisition reverse knowledge transfer is affected by acquirers’ prior related knowledge. Keywords M&A, Chinese firms, Post-acquisition integration, Absorptive capacity, Reverse knowledge transfer, Pr
This Paper Is Included in the Proceedings of the 12th Usenix Symposium on Operating Systems Design and Implementation (osdi '16). Light-weight Contexts: an Os Abstraction for Safety and Performance Light-weight Contexts: an Os Abstraction for Safety and Performance

We introduce a new OS abstraction—light-weight contexts (lwCs)—that provides independent units of protection , privilege, and execution state within a process. A process may include several lwCs, each with possibly different views of memory, file descriptors, and access capabilities. lwCs can be used to efficiently implement roll-back (process can return to a prior recorded state), isolated address spaces (lwCs within the process may have different views of memory, e.g., isolating sensitive data from network-facing components or isolating different user sessions), and privilege separation (in-process reference monitors can arbitrate and control access). lwCs can be implemented efficiently: the overhead of a lwC is proportional to the amount of memory exclusive to the lwC; switching lwCs is quicker than switching kernel threads within the same process. We describe the lwC abstraction and API, and an implementation of lwCs within the FreeBSD 11.0 kernel. Finally, we present an evaluation of common usage patterns, including fast roll
Barriers to Nurse-Patient Communication in Cardiac Surgery Wards: A Qualitative Study

Background: An appropriate and effective nurse-patient communication is of the most important aspect of caring. The formation and continuation of such a relationship depends on various factors such as the conditions and context of communication and a mutual understanding between the two. A review of the literature shows that little research is carried out on identification of such barriers in hospital wards between the patients and the healthcare staff. Objectives: The present study was therefore conducted to explore the experiences of nurses and patients on communication barriers in hospital cardiac surgery wards. Design and Methods: This qualitative research was carried out using a content analysis method (Graneheim & Lundman, 2004). The participants were selected by a purposeful sampling and consist of 10 nurses and 11 patients from the cardiac surgery wards of three teaching hospitals in Tehran, Iran. Data was gathered by unstructured interviews. All interviews were audio-taped and transcribed verbatim. Results: Findings were emerged in three main themes including job dissatisfaction (with the sub-themes of workload tension and decreased motivation), routine-centered care (with the sub-themes of habitual interventions, routinized and technical interventions, and objective supervision), and distrust in competency of nurses (with the sub-themes of cultural contrast, less responsible nurses, and their apathy towards the patients). Conclusions: Compared to other studies, our findings identified different types of communication barriers depending on the nursing settings. These findings can be used by the ward clinical nursing managers at cardiac surgery wards to improve the quality of nursing care.
SELF-REGULATED LEARNING IMPLEMENTED BY THE STUDENTS OF ELEMENTARY SCHOOL IN BULELENG SUB-DISTRICT

This study highlights the implementation of each aspect of self-regulated learning in cyclical phase which was proposed by Zimmerman and Moylan (2009). With an aim to identify whether elementary school students in Buleleng Subdistrict implement self-regulated learning or not, this study used descriptive qualitatively research design to describe comprehensively the implementation of self-regulated learning in elementary school students. SDN 3 Banjar Jawa, SDN 4 Banyuasri, SD Laboratorium Undiksha, and SDN 4 Kampung Baru became the setting of this study because those schools have implemented curriculum 2013 which means that those schools have implicitly implemented self-regulated learning. There were 544 students from grade 1 until 6 which were chosen randomly as the subject of this study. The instruments used in this study were observation checklist, questionnaire which was consisted of 20 statements which had been distributed to subject of the study, and also interview guide which was used to interview several students from the subject of the study. The result of the study shows that most of elementary school students in Buleleng sub-district had implemented self-regulated learning. The data were collected by doing observation with the observation checklist, distributing questionnaire. The observation checklist was used to find out the implementation of self-regulated learning in the classroom. The questionnaire items were developed from each aspect of self-regulated learning in Zimmerman’s cyclical phase. This study focuses on elementary schools which have implemented curriculum 2013 as their educational curriculum. It is because the implementation of student-centered learning as well as self-regulated learning of the students will be seen in the learning process. In the implementation of self-regulated learning, this study emphasizes on identifying aspects of self-regulated learning in Zimmerman (2002) and analyzing the aspects which are mostly implemented by the students.
Entropy Based Feature Selection for Lacunarity Analysis of Position Specific Motif Matrices of Promoter Sequences

Analysis of biological sequences is gaining importance due to the development in sequencing technologies. It is a challenging research since the amount of sequence data being generated is increasing exponentially. In this study we attempt to do feature selection in promoter sequences using entropy values which reduces the dimension of the position specific motif matrices (PSMMs) of the promoter sequences. Later, we reconstruct the PSMMs using the entropy selected motifs/features and perform lacunarity analysis on the reconstructed PSMMs. This helps us to analyze the similarity existing between the promoter sequences. For experiments we use dataset created using NCBI. The results obtained using reduced motifs are encouraging in terms of differentiating promoters when compared to the results using complete set of motifs. From the experiments entropy seems to be a powerful measure to select features which increases the discriminative capability of lacunarity analysis.
‘Impact’, educational influence and the practice of shared expertise

Abstract This paper argues that participants and locals should be seen as at the centre of all development, including international and health development work. Consequently, in contexts of health and wellbeing, patients should be seen as active participants, which also implies the need for the independence and freedom of all and the development of dialogical spaces in which all may negotiate what counts as a life worth living. ‘Impact’, on this view, should be seen from a lifeworld perspective of evaluating the effects of dynamic evolving practices where all are seen potentially as donors and beneficiaries within contexts of mutually negotiated reciprocal relationships. Data drawn from extensive fieldwork with local trauma surgeons, midwives and healthcare personnel in rural Cambodia provide the basis of new perceptions about processes of ‘passing on’ knowledge and expertise. The ideas presented have potential implications for normative understandings of the social organisation of healthcare in domestic and international settings.
Tourist's motivation and behavioural intention between sun and sand destinations

Beaches in Malaysia are becoming attractive destinations for tourists all over the world because of their tranquil beauty. Previous research indicated the impact of motivation on behaviour intentions. Thus, the mediating role of tourists' satisfaction conceptualised as tourists' motivation on behavioural intention in the tourism industry was investigated in this study. Participants of this study constituted 165 international tourists. Smart- Partial Least Squares (PLS) was performed by the Variance Based-Structural Equation Modeling (VB-SEM) to test the hypothesis. The mediating role of tourist satisfaction on the relationship between tourist motivation and behaviour intentions was highlighted in this study. The path relationship revealed that the mediating variable has a highly significant indirect effect. It was also shown that tourists are attracted by sun and sand destinations. It further suggests that researchers should conduct more studies to know more about what information travellers will tell to their significant persons such as friends, family, colleagues, etc. about their tourism experience.
The globular cluster system of NGC 5846 revisited: colours, sizes and x-ray counterparts

Context. NGC 5846 is a giant elliptical galaxy with a previously well studied globular cluster system (GCS), known to have a bimodal colour distribution with a remarkably high red fraction. Aims. Here we revisit the central galaxy regions searching for new globular cluster (GC) candidates, and measure magnitudes, colours and sizes for them. We also search for their X-ray counterparts. Methods. We use archival Hubble Space Telescope WFPC2 images, from which we modelled and subtracted the host light distribution to increase the available sample of GCs. We performed photometry on the central objects, and measured sizes and coordinates for the entire GC system known in this galaxy. Results. We detect two dozen previously unknown GC candidates in the central regions. Reliable sizes are obtained for about 60 GCs; their typical effective radii are in the range 3−5 pc. The largest clusters are located in the central regions. We find 7 X-ray counterparts to GCs, most of them in the central region. They are among the most luminous X-ray sources in NGC 5846. They are also optically luminous, compact and belong to the red subpopulation. Conclusions. The GCS of NGC 5846 is composed of relatively luminous X-ray sources.
EM-Sense: Touch Recognition of Uninstrumented, Electrical and Electromechanical Objects

Most everyday electrical and electromechanical objects emit small amounts of electromagnetic (EM) noise during regular operation. When a user makes physical contact with such an object, this EM signal propagates through the user, owing to the conductivity of the human body. By modifying a small, low-cost, software-defined radio, we can detect and classify these signals in real-time, enabling robust on-touch object detection. Unlike prior work, our approach requires no instrumentation of objects or the environment; our sensor is self-contained and can be worn unobtrusively on the body. We call our technique EM-Sense and built a proof-of-concept smartwatch implementation. Our studies show that discrimination between dozens of objects is feasible, independent of wearer, time and local environment.
A search for Warm-Hot Intergalactic Medium features in the X-ray spectra of Mkn 421 with the XMM-Newton RGS

We present the high-resolution X-ray spectra of Mkn 421 obtained in November 2003 with the RGS aboard the XMM-Newton satellite. This Target of Opportunity observation was triggered because the source was in a high state of activity in the X-ray band. These data are compared with three archival RGS observations of the same source performed in November and December 2002 and one in June 2003. We searched for the presence of absorption features due to warm-hot intergalactic medium (WHIM). We identify various spectral features, most of which are of instrumental origin. With the sensitivity pr ovided by our spectra we were able to identify only two lines of astronomical origin, namely features at 23.5 ˚ A, probably due to

Cognitive-Motor Interference in Multiple Sclerosis: A Systematic Review of Evidence, Correlates, and Consequences

Individuals with multiple sclerosis (MS) regularly exhibit deficits in motor and cognitive function. Recent evidence suggests that these impairments are compounded when motor and cognitive task are performed simultaneously such as walking while talking. The changes incurred during simultaneous performance of motor and cognitive tasks are a result of cognitive-motor interference (CMI) and operationalized as dual task costs (DTC). Recently in MS, research has been conducted to understand and analyze the impact of CMI. The purpose of this paper was to review the current literature related to the evidence, correlates, and consequences of CMI in MS. Relevant literature was collected from the results of a PubMed search for terms including “Cognitive-motor interference” or “Cognitive-motor interaction” or “Dual task” and “multiple sclerosis. ” Overall, 20 papers were included for review which focused on CMI during balance and walking tasks. The finding that there is a lack of evidence pertaining to changes in the cognitive domain as well as to the specific consequences of CMI in MS was noted. Future work should aim to fill these gaps and ultimately investigate the usefulness of targeted interventions in reducing the deleterious effects of CMI in individuals with MS.
Teamwork in the Automobile Industry - an Anglo-German Comparison

Teamwork in the automotive industry varies significantly from plant to plant. This article compares teamwork in four automobile plants in Germany and Britain, and addresses two questions: (1) Do different models of teamwork fit into a bi-polar model of teamwork, being either innovative or structural conservative? (2) Do current models of teamwork signify a development towards post-fordism, or are they merely part of a neo-fordist rationalisation of production? The following answers are suggested: (1) Teamwork in different motor-car plants cannot be categorised in a bi-polar model; rather do they represent a continuum. (2) Teamwork moves manu- facturing away from traditional taylorist models of production, but does not over-come Taylorism altogether.
A Complex Structural Variation on Chromosome 27 Leads to the Ectopic Expression of HOXB8 and the Muffs and Beard Phenotype in Chickens

Muffs and beard (Mb) is a phenotype in chickens where groups of elongated feathers gather from both sides of the face (muffs) and below the beak (beard). It is an autosomal, incomplete dominant phenotype encoded by the Muffs and beard (Mb) locus. Here we use genome-wide association (GWA) analysis, linkage analysis, Identity-by-Descent (IBD) mapping, array-CGH, genome re-sequencing and expression analysis to show that the Mb allele causing the Mb phenotype is a derived allele where a complex structural variation (SV) on GGA27 leads to an altered expression of the gene HOXB8. This Mb allele was shown to be completely associated with the Mb phenotype in nine other independent Mb chicken breeds. The Mb allele differs from the wild-type mb allele by three duplications, one in tandem and two that are translocated to that of the tandem repeat around 1.70 Mb on GGA27. The duplications contain total seven annotated genes and their expression was tested during distinct stages of Mb morphogenesis. A continuous high ectopic expression of HOXB8 was found in the facial skin of Mb chickens, strongly suggesting that HOXB8 directs this regional feather-development. In conclusion, our results provide an interesting example of how genomic structural rearrangements alter the regulation of genes leading to novel phenotypes. Further, it again illustrates the value of utilizing derived phenotypes in domestic animals to dissect the genetic basis of developmental traits, herein providing novel insights into the likely role of HOXB8 in feather development and differentiation.
Transductive Inference for Text Classification using Support Vector Machines

This paper introduces Transductive Support Vector Machines (TSVMs) for text classi(cid:12)-cation. While regular Support Vector Machines (SVMs) try to induce a general decision function for a learning task, Transduc-tive Support Vector Machines take into account a particular test set and try to minimize misclassi(cid:12)cations of just those particular examples. The paper presents an analysis of why TSVMs are well suited for text classi(cid:12)cation. These theoretical (cid:12)ndings are supported by experiments on three test collections. The experiments show substantial improvements over inductive methods, espe-ciallyfor smalltraining sets, cutting the number of labeled training examples down to a twentieth on some tasks. This work also proposes an algorithm for training TSVMs e(cid:14)-ciently, handling 10,000 examples and more.
