Integrated Link-System Level Simulation Platform for the Next Generation WLAN - IEEE 802.11ax

As the most widely used standards for wireless local area network (WLAN), IEEE 802.11 standards are continuously amended by introducing new techniques so as to meet the increasing demands. In order to verify the performance of amended protocols, network simulation is considered as a significant method. However, as far as we know, current simulation tools are only for either media access control layer (MAC) or physical layer (PHY). The separate simulation of MAC and PHY can hardly evaluate the performance of IEEE 802.11ax in whole system level for authenticity and objectivity. Hence, the next generation WLAN (IEEE 802.11ax) requires integrated system simulation to take impacts of both MAC and PHY techniques into account. Moreover, IEEE 802.11ax introduces some new techniques, such as orthogonal frequency division multiple access (OFDMA), multi-user multiple input multiple output (MU- MIMO) and non-continuous channel bonding. In this paper, we design and further implement the integrated link-system level simulation platform, which makes it possible to evaluate the new technologies for IEEE 802.11ax. Moreover, we propose a MAC protocol combining OFDMA, MU-MIMO, non-continuous channel bonding and link adaptation and further evaluate its performance. Finally, we validate performance gains of IEEE 802.11ax through simulation, and the simulation results show that IEEE 802.11ax has obviously higher throughput, better quality of service (QoS) and higher multi- channel efficiency. To the best of our knowledge, this is the first work to design and implement simulation platform for IEEE 802.11ax with an integrated link- system level framework.
Examining Immediate and Long-Term Efficacy of Rape Prevention Programming with Racially Diverse College Men.

The authors investigated the short- and long-term (5-month) effectiveness of a theoretically driven, programmatic rape prevention intervention on a sample of primarily White and Black college men. A racially diverse sample was included, and the potential effectiveness of both a culturally relevant and a traditional colorblind intervention was assessed. In contrast to earlier investigations, which have consistently reported an overall rebound of scores at the follow-up assessment, results from a hierarchical cluster analysis indicated 3 patterns of treatment response: improving, deteriorating, and rebounding. Results also indicated that Black students in the culturally relevant treatment condition were more cognitively engaged in the intervention than their peers in the traditional treatment condition.
Right-Wing Parties and Anti-foreigner Sentiment in Europe

Raijman, and Gorodzeisky (SRG hereafter) examine changes in Europeans’attitudes toward foreigners between 1988 and 2000. SRG show that during this period there was a dramatic increase in anti-foreigner sentiment in all of the 12 countries they studied.1 They use hierarchical linear models to investigate the extent to which this was influenced by differences in individual and country-level characteristics. SRG find little support for traditional competition or group threat models that routinely inform our understanding of prejudice and ethnic collective action (e.g., see Olzak 1992; Quillan 1995; Scheepers, Gijberts, and Coenders 2002). Instead, SRG demonstrate recent changes in the strength of the relationship between the political orientation of respondents and antiforeigner sentiment. Specifically, over time, individuals who locate themselves more to the right of the political spectrum have become increasingly intolerant toward foreigners (p. 441). Where people live also matters: anti-foreigner sentiment is higher in countries with stronger support for extreme right-wing parties (ERPs hereafter). By drawing our attention to the role of political factors in a debate that has been heavily oriented toward economic explanations, SRG make an important contribution to our understanding of the causes of anti-foreigner sentiment. In this comment, we extend SRG’s findings on the relationship between politics and prejudice. SRG claim that anti-foreigner sentiment is higher where the prevalence of support for the extreme right is strong. We argue that this is an overgeneralization. Sharp ideological differences between ERPs on racial issues, especially across countries, matter. These ideological differences, we suggest, not only affect attitudes across countries but also interact with attitudes at the individual level. Further, we demonstrate that because SRG treat all ERPs as if they are one type, outlier countries have a significant effect on their results. In contrast, our results are more robust because we consider the type of racism each ERP exhibits.
Meaning and suffering in organizations

Purpose – The purpose of this paper is to explore the role of suffering for meaning making and spirituality in organizational contexts.Design/methodology/approach – The paper explores how organizational spaces may be created for meaning making and how this is linked to the idea of compassion.Findings – The paper suggests that while suffering has been explored in organizations, it has not been studied relative to existential meaning making. This is identified as a significant gap in research on organizational spirituality. The paper attempts to fill this gap and suggests that the study of suffering has to separate suffering as an objective phenomenon, which should be eliminated in organizations, from suffering as a subjective experience in which meaning may be found. It is also proposed that, for existential meaning to be uncovered in the face of suffering, organizational spaces have to be created in which such meaning making can take place.Originality/value – The paper suggests that suffering can be a pat.
Digital rubbing: playful and intuitive interaction technique for transferring a graphic image onto paper with pen-based computing

In this paper, we introduce digital rubbing, which is a playful and intuitive interaction technique for transferring a graphic image directly onto paper. We designed TransPen and MimeoPad to realize digital rubbing. With these drawing tools, children and adults can use rubbing motions to transfer a digital image directly to paper and produce a drawing with a personal touch and natural texture, just as in traditional rubbing. We expect that digital rubbing technique would be useful in arts and design as a new way of expression in the process of drawing and editing ideas. In addition, the suggested interaction devices have the full potential to become new drawing toys for children.
Ceiling Effects Prevent Further Improvement of Transcranial Stimulation in Skilled Musicians

The roles of the motor cortex in the acquisition and performance of skilled finger movements have been extensively investigated over decades. Yet it is still not known whether these roles of motor cortex are expertise-dependent. The present study addresses this issue by comparing the effects of noninvasive transcranial direction current stimulation (tDCS) on the fine control of sequential finger movements in highly trained pianists and musically untrained individuals. Thirteen pianists and 13 untrained controls performed timed-sequence finger movements with each of the right and left hands before and after receiving bilateral tDCS over the primary motor cortices. The results demonstrate an improvement of fine motor control in both hands in musically untrained controls, but deterioration in pianists following anodal tDCS over the contralateral cortex and cathodal tDCS over the ipsilateral cortex compared with the sham stimulation. However, this change in motor performance was not evident after stimulating with the opposite montage. These findings support the notion that changes in dexterous finger movements induced by bihemispheric tDCS are expertise-dependent.

This article reviews the present state and trends in the development of key parts of controlled induction motor drive systems: converter topologies, modulation methods, as well as control and estimation techniques. Two- and multilevel voltage-source converters, current-source converters, and direct converters are described. The main part of all the produced electric energy is used to feed electric motors, and the conversion of electrical power into mechanical power involves motors ranges from less than 1 W up to several dozen megawatts.
Grassroots Suggestions for Linking Native-Language Learning, Native American Studies, and Mainstream Education in Reservation Schools with Mixed Indian and White Student Populations

Indigenous-language education is critical in the rural and small-town communities with mixed native/non-native populations that constitute the headwaters of many dying tongues. Emerging from interviews conducted in 2002 and 2003 on the Flathead Indian Reservation with 89 study participants holding diverse perspectives is the need for a unifying reservation-wide preK-16 language curriculum that will bring about continuous and meaningful connections (1) across Indian-language-education programmes, (2) between Indian-language classrooms and mainstream classrooms, and (3) between native language education and Native American Studies. This paper considers the grassroots suggestions for building such a curriculum encountered among cultural and community leaders, educators and parents, historians and politicians, Indians and non-Indians, and advocates and sceptics of indigenous-language education. The study findings indicate that framing indigenous-language learning as part of place-based multicultural education is a promising approach. Prospects for indigenous-language survival can be enhanced by moving native-language education in a direction that is acceptable to and beneficial for most, if not all, members of mixed communities in a global age.
Querying the Paradox of Caring Labor

Caring labor has long been considered “women's work” in economics. It is a problematic concept because its affective dimension means that it does not fit neatly into the category of work, and dominant gender ideology constructs it as a “labor of love. ” The problem, according to feminist economists, is that the nature of care and the dependency of those receiving care imply that caregivers must genuinely care about those to whom their well-being is entrusted. From a global political economy perspective, the problem is that migrant populations—disenfranchised and disposable—provide much of the care work that the more prosperous world depends on. The feminist economics work on care frames it in terms of households and markets, which leaves in place its racialized, feminized, and heteronormative connotations. This paper argues for using a queer/global political economy lens that focuses on care work as sites of biopolitics. This analytic move allows feminist scholars to examine its affective dimension without reinscribing it as women's work.
Simultaneous German-English lecture translation.

In an increasingly globalized world, situations in which people of different native tongues have to communicate with each other become more and more frequent. In many such situations, human interpreters are prohibitively expensive or simply not available. Automatic spoken language translation (SLT), as a cost-effective solution to this dilemma, has received increased attention in recent years. For a broad number of applications, including live SLT of lectures and oral presentations, these automatic systems should ideally operate in real time and with low latency. Large and highly specialized vocabularies as well as strong variations in speaking style ‐ ranging from read speech to free presentations suffering from spontaneous events ‐ make simultaneous SLT of lectures a challenging task. This paper presents our progress in building a simultaneous German-English lecture translation system. We emphasize some of the challenges which are particular to this language pair and propose solutions to tackle some of the problems encountered.
The “no-reflow” phenomenon: basic science and clinical correlates

To achieve early and complete reperfusion of the myocardium in acute coronary syndromes is the daily challenge for every physician in clinical cardiology. However, restoration of epicardial blood flow by thrombolysis, primary angioplasty or bypass surgery does not necessarily imply complete reperfusion, even if the target stenosis is adequately removed or bypassed. The amount of microvascular integrity may limit reperfusion to the previously ischaemic tissue despite complete restoration of epicardial vessel diameters. A 74 year old man with acute distress is admitted to the emergency room because of acute onset of severe, substernal, crushing chest pain two hours ago. He has never suffered from similar symptoms before. The ECG shows ST segment elevation in leads I, aVL, V2–V4. After aspirin and heparin, the patient is immediately transferred to the catheterisation laboratory. Coronary angiography confirms a thrombotic occlusion of the proximal left anterior descending artery. The guide wire easily crosses the occlusion. After coronary artery balloon dilatation and stent implantation the epicardial artery appears to have gained sufficient luminal diameter. However, the contrast medium is only slowly conveyed to the distal artery and not adequately washed out. Even the final angiogram after glyceryl trinitrate in different projections shows no satisfactory flow albeit no visible flow limiting obstacles, such as coronary artery dissection or recurrent thrombus formation. The battle, undertaken to restore myocardial blood supply, seems to be lost and won, finally leading to compromised tissue perfusion despite a successful restoration of patency to the epicardial blood vessel. A bolus of abciximab, followed by a continuous infusion, is initiated. ST segment elevations resolve only slightly during the next hours; the patient requires prolonged intensive medical care because of recurrent pulmonary oedema. Finally, the patient is stabilised on cardiovascular medication including an angiotensin converting enzyme (ACE) inhibitor, oxygen, and aspirin. The echocardiography shows …
Are cervical vestibular evoked myogenic potentials sensitive to changes in the vestibular system associated with benign paroxysmal positional vertigo?

Abstract Objective: This study aimed to correct the notion regarding the efficacy of cervical vestibular evoked myogenic potentials (cVEMP) in identifying benign paroxysmal positional vertigo (BPPV)-associated changes in the peripheral vestibular system. Study design: A static group comparison research design was used to compare the cVEMP results of a group of individuals with BPPV in the age range of 30–60 years against age- and gender-matched healthy individuals. The cVEMP were recorded with tone bursts of 500 Hz gated using a Blackman window. The 95dB nHL tone bursts were presented at the rate of 5.1 Hz. The response was band-pass filtered between 10 and 1500 Hz and amplified by a factor of 5000. The response window was set to 70 ms, which was inclusive of a 15-ms pre-stimulus recording. Results: Responses were analysed for individual peak latencies, peak-to-peak amplitudes, and asymmetry ratio and compared between the groups using mixed analysis of variance and an independent samples t-test. The results revealed no significant difference in the latencies of P13 and N23 (p > 0.05). There was also a lack of difference for peak-to-peak amplitude and asymmetry ratio between the two groups (p > 0.05). Conclusion: There was no difference in the latency or amplitude measures between healthy individuals and the individuals with BPPV, which undermines the utility of cVEMP in identifying changes associated with BPPV in the peripheral vestibular system.
A tool to monitor and support physical exercise interventions for MCI and AD patients

This paper presents a tool to monitor and support the execution of common physical exercise interventions targeting people with Mild Cognitive Impairment (MCI), Alzheimer's Disease (AD) and elderly in general. Our tool aims (a) to stimulate and guide patients within physical exercise programs, (b) to monitor patient capacity to perform exercises suggested by clinicians and provide objective feedback and (c) to enable early diagnosis of significant changes in the physical capacity of users over time. Our tool incorporates a virtual 3D trainer, demonstrating prescribed exercises; currently, arms lifting, arms stretching, torso bending and torso twisting are supported. Utilizing a low-cost depth camera and markerless skeletal joint estimation, our tool monitors movement during exercise execution, evaluating patient performance with a set of metrics introduced herein. Through preliminary experimental analysis, our metrics were found of significant potential to discriminate among good and bad executions of the currently supported exercises.
The Relationship Between Religious Coping and Psychological Distress in Parents of Children with Cancer

Abstract This study examined the degree of psychological distress experienced by parents of children with cancer in relation to five religious coping methods: collaborative, active surrender, passive deferral, pleading for direct intercession, and self-directed religious coping. Parents of 166 children with cancer from four hospitals completed the Religious Coping Methods to Gain Control subscale of the Religious/ Spiritual Coping (RCOPE) scale and the Brief Symptom Inventory (BSI). On the average, BSI scores indicated high levels of distress compared with adult norms. Collectively, the five coping methods accounted for 19% of the variance in participants' psychological distress. As predicted, collaborative religious coping was uniquely associated with lower distress. Contrary to hypotheses, pleading for direct intercession was associated with greater reported distress.
Robust voting algorithm based on labels of behavior for video copy detection

This paper presents an efficient approach for copies detection in a large videos archive consisting of several hundred of hours. The video content indexing method consists of extracting the dynamic behavior on the local description of interest points and further on the estimation of their trajectories along the video sequence. Analyzing the low-level description obtained allows to highlight trends of behaviors and then to assign a label of behavior to each local descriptor. Such an indexing approach has several interesting properties: it provides a rich, compact and generic description, while labels of behavior provide a high-level description of the video content. Here, we focus on video Content Based Copy Detection (CBCD). Copy detection is problematic as similarity search problem but with prominent differences. To be efficient, it requires a dedicated on-line retrieval method based on a specific voting function. This voting function must be robust to signal transformations and discriminating versus high similarities which are not copies. The method we propose in this paper is a dedicated on-line retrieval method based on a combination of the different dynamic contexts computed during the off-line indexing. A spatio-temporal registration based on the relevant combination of detected labels is then applied. This approach is evaluated using a huge video database of 300 hours with different video tests. The method is compared to a state-of-the art technique in the same conditions. We illustrate that taking labels into account in the specific voting process reduces false alarms significantly and drastically improves the precision.
Realizing the Potential of Behavioral Intervention Technologies

Behavioral intervention technologies (BITs) apply behavioral and psychological intervention strategies by using digital media to target behaviors, cognitions, and emotions in support of physical and mental health. BITs offer promising opportunities to expand psychological practice. However, to realize the potential of BITs, psychologists must understand both the possibilities and the limitations associated with using technology to advance psychology. We review examples of the most cutting-edge BITs and discuss features that differentiate BITs from traditional modes of delivery. We highlight major challenges in designing BITs, including adherence, engagement, technological and interventional obsolescence, multidisciplinary collaboration, and a reliance on psychological skeuomorphisms. Psychologists who do not understand the conceptual and applied considerations involved in creating BITs risk being left out of the development of BITs in the future. Teaming psychologists with experts in technology will help to promote novel interventions rather than using technology to disseminate existing treatments.
Signature-driven multi-target tracking

Tracking multiple maneuvering targets remains a challenge because of clutter and spurious targets. We propose a Signature-Driven multiple target Tracking (SDT) method which fuses target data in spectral, spatial and temporary spaces to form signatures of targets. Markov properties of target features and dynamics are well defined in the signature of targets so that the data association process in SDT is efficient and effective. The experimental results have shown its superior performance.
An efficient clustering algorithm for trajectory points in Digital Movies Mobile Playing Systems

In the paper, an efficient spatial clustering algorithm, the improved DBSCAN (Density Based Spatial Clustering of Applications with Noise), is proposed, for cluster analysis of trajectory points gathered from Digital Movies Mobile Playing Systems(DMSs). By searching the density of points which are greater than a given threshold in rural areas, the density-reachable maximum movie playing clusters are established. Moreover, the improved DBSCAN algorithm is based on the adjacent list structure to save space and time resources. The paper also adopts the real mobile projection GPS data in a province to analyze the clusters of movie trajectory points. Experiment results show that the presented algorithm can not only reflect quickly the overall distribution of the projection location information, but dig out the projection regions with high density. And the conclusions drawn from the paper are valuable for the management department to evaluate the tasks of the projectionists.
The Incongruence of the Breton Linguistic Landscape for Young Speakers of Breton

Abstract Globalisation processes, often accused of imposing uniformity the world over, also open up opportunities for minorities (including linguistic ones) to exploit a variety of spaces for self-definition and self-expression. The expansion in the use of minority languages in public signage is one consequence of this present phase of reorientation in normative space. On one level, the appearance of the Breton language in more and more public places in Brittany has been welcomed by language activists as a step forward, but on another level, such tokenism has not necessarily led to an expansion in the public use of the language on a more informal basis. This paper explores the effect of the symbolic use of the language on young Breton speakers being educated in immersion and bilingual schools in one town in Brittany and the dynamic that results from their encountering Breton in one establishment that has come to encapsulate ‘High Modernity’ the world over.
