PROCEEDINGS of the HUMAN FACTORS AND ERGONOMICS SOCIETY 45th ANNUAL MEETING- 2001 USE OF INCREMENTAL ADAPTATION AND HABITUATION REGIMENS FOR MITIGATING OPTOKINETIC SIDE EFFECTS

The use of incremental and repeated exposures regimens have been put forth as effective means to mitigating visually induced motion sickness based on the Dual Process Theory (DPT) (Groves & Thompson, 1970) of neural plasticity. In essence, DPT suggests that by incrementing stimulus intensity the depression opponent process should exert greater control over the net outcome (e.g. motion sickness) than the sensitization opponent process, thereby minimizing side effects. This conceptual model was tested by empirically validating the effectiveness of adaptation, incremental adaptation, habituation, and incremental habituation regimens to mitigate side effects arising from exposure to an optokinetic drum. Forty college students from the University of Central Florida participated in the experiment and were randomly assigned to a treatment with efforts taken to balance for gender and motion sickness susceptibility. Results indicated that overall, the application of an incremental regimen is effective in reducing side effects (e.g. malaise and dropout rates) when compared to a non-incremented regimen, whether it be a one time or repeated exposure. Furthermore, application of the Motion History Questionnaire (MHQ) (Graybiel & Kennedy, 1965) to identify high and low motion sickness susceptible individuals proved effective. Finally, gender differences were not found in this experiment as a result of balancing susceptibility within the gender subject variable.
Editorial: latent class analysis to improve confidence in the diagnosis of IBS

fold), breast cancer (1.75-fold) and hematologic cancers (twofold). These increased cancer death rates over the general population certainly are exacerbated by shared risk factors such as obesity, lack of exercise, smoking and alcohol consumption. Cardiovascular deaths are close behind non-oesophageal cancers in the 71% increased risk of overall mortality in the Danish Barrett’s patients. Although the rates compared to the general population were similar for myocardial infarction, they were 20–40% increased for subarachnoid bleed (1.21 adjusted hazard risk), congestive heart failure (1.29) and venous thromboembolism (1.40). It was only among the Barrett’s patients with oesophageal cancer that the mortality rate associated with this cancer exceeded the cardiovascular causes of death. Maybe I can envision a day when a conversation with a new Barrett’s patient might say – ‘Mr. Jones, your endoscopy shows Barrett’s oesophagus but your genomic blood tests show little to no risk of getting oesophageal cancer. Maybe to be certain, let’s repeat an endoscopy in 5–10 years. However, you have a two-fold increase for death from non-oesophageal cancers and heart disease. You should stop smoking, decrease your alcohol consumption, follow-up with me for your colon cancer screening (also mammogram if a woman) and consult your internist or cardiologist on Healthy Heart Habits including age-appropriate cardiac testing and use of low dose aspirin and statins’. In a perfect world, this might really help our Barrett’s patients the most.
Task Complexity and Second Language Narrative Discourse

Researchers need to identify what differences second language tasks set at different levels of complexity make to measures of learner language, in order to provide a basis for pedagogic decisions about grading and sequencing such tasks. This study examined differences in the production of oral narrative discourse by 12 adult second language learners of English on narrative tasks that simulated the ability to describe events in the Here-and-Now versus the There-and-Then. Target-like use, propositional and syntactic complexity, lexical load, pausing, and utterance length were measured under the two conditions. A MANOVA showed significant differences between the two conditions. Separate ANOVAs for each measure showed a significant difference between the two conditions for measures of lexical load and an almost significant difference for measures of target-like use. The more complex There-and-Then condition elicited greater accuracy and a higher ratio of lexical to grammatical words. There was also a trend suggesting greater utterance length for narratives performed under the simpler Here-and-Now condition. These results support the claim that complex tasks elicit less fluent, but more accurate and complex production than do simpler tasks.
The Netlog Corpus. A Resource for the Study of Flemish Dutch Internet Language

Although in recent years numerous forms of Internet communication ― such as e-mail, blogs, chat rooms and social network environments ― have emerged, balanced corpora of Internet speech with trustworthy meta-information (e.g. age and gender) or linguistic annotations are still limited. In this paper we present a large corpus of Flemish Dutch chat posts that were collected from the Belgian online social network Netlog. For all of these posts we also acquired the users' profile information, making this corpus a unique resource for computational and sociolinguistic research. However, for analyzing such a corpus on a large scale, NLP tools are required for e.g. automatic POS tagging or lemmatization. Because many NLP tools fail to correctly analyze the surface forms of chat language usage, we propose to normalize this anomalous' input into a format suitable for existing NLP solutions for standard Dutch. Additionally, we have annotated a substantial part of the corpus (i.e. the Chatty subset) to provide a gold standard for the evaluation of future approaches to automatic (Flemish) chat language normalization.
Light-weight immaterial particle displays with mid-air tactile feedback

Immaterial mid-air displays formed of flowing light-scattering particles are becoming feasible for displaying information in thin air and interacting with it. With light-weight desktop fogscreens and low-cost hand tracking, the user can easily and unobtrusively interact with virtual information. Any real objects can be seen or reached through the screen, as it is permeable and almost intangible. However, no tactile feedback can be perceived when interacting with a mid-air display. Our contribution in this paper is the construction of an interactive mid-air fogscreen employing ultrasonic phased arrays in order to create mid-air tactile feedback. The feedback is suitable for small desktop-sized fogscreens. This creates a mixed reality setup where real objects and e.g., augmented reality content can be brought closer together conceptually and physically. In an experimental evaluation of the mid-air tactile feedback for the fogscreen we found no statistically significant difference in performance, but the mid-air tactile feedback was slightly preferred over no tactile feedback by the users. They found the tactile feedback as more engaging.
Genre-based curricula: multilingual academic literacy in content and language integrated learning

Abstract This study addresses academic literacy in content and language integrated learning (CLIL) secondary education. More precisely, this paper focuses on attempts to meet modern standards for language competences set in areas like Europe, where the notion involves multilingual academic competence. The study centres on new proposals for language organisation in CLIL education based on genres resulting in a multilingual genre map across the curriculum. The feasibility of this model was proven in the author's national context in an attempt to improve language competence levels. The study provides a revision of the language theory in CLIL classroom practice that sits ill with traditional structural formalism and is better served through multilingual genre-based, functional semiotic models. Textual examples and genres will come from the area of History.
Biofeedback and Counseling for Stress and Anxiety Among College Students

With the rise in stress and anxiety among college students, there is a need for more comprehensive and effective counseling options for counselors in college counseling centers. This study investigated the impact of using biofeedback and brief counseling in treating stress and anxiety in an ethnically diverse college student population. Results indicated that participants who received biofeedback training and counseling had greater reduction in anxiety symptoms than did participants who received counseling alone. Implications for augmenting biofeedback training to traditional college counseling model are discussed.
International Journal of Behavioral Nutrition and Physical Activity Reliability and Relative Validity of a Child Nutrition Questionnaire to Simultaneously Assess Dietary Patterns Associated with Positive Energy Balance and Food Behaviours, Attitudes, Knowledge and Environments Associated with Health

Background: Food behaviours, attitudes, environments and knowledge are relevant to professionals in childhood obesity prevention, as are dietary patterns which promote positive energy balance. There is a lack of valid and reliable tools to measure these parameters. The aim of this study was to determine the reliability and relative validity of a child nutrition questionnaire assessing all of these parameters, used in the evaluation of a community-based childhood obesity prevention project.
Magnetic Field-Based Positioning Systems

This paper provides an introductory survey on the various systems that exploit magnetic fields for positioning. Such systems find applications in those scenarios, both indoors and outdoors, where global navigation satellite systems are not available or fail to provide information with the needed accuracy. While the main idea of using electromagnetic fields to provide position information dates back to the past century, new application-led research on this topic has emerged in recent years. Results have expanded the application range of magnetic positioning technologies and form now a domain of knowledge that enables realization of positioning systems applicable to indoor and outdoor environments. This paper provides the main characteristics of different positioning systems with focus on those solutions that are based on low-frequency magnetic fields. Some background theory is presented and positioning results from the literature are analyzed and compared.
Annotating Dialogue Acts to Construct Dialogue Systems for Consulting

This paper introduces a new corpus of consulting dialogues, which is designed for training a dialogue manager that can handle consulting dialogues through spontaneous interactions from the tagged dialogue corpus. We have collected 130 h of consulting dialogues in the tourist guidance domain. This paper outlines our taxonomy of dialogue act annotation that can describe two aspects of an utterances: the communicative function (speech act), and the semantic content of the utterance. We provide an overview of the Kyoto tour guide dialogue corpus and a preliminary analysis using the dialogue act tags.
A Context Sensitive Maximum Likelihood Approach to Chunking

In Brill's (1994) groundbreaking work on parts-of-speech tagging, the starting point was to assign each word its most common tag. An extension to this first step is to utilize the lexical context (i.e., words and punctuation) surrounding the word. This approach could obviously be used for ordering tags into higher order units (referred to as chunks) using chunk labels.
Autonomic Reactivity to Infant Crying in Maltreating Mothers

We examined autonomic reactivity to infant crying in a sample of 42 maltreating and 38 non-maltreating mothers. Exploratively, we tested if differential reactivity was related to child neglect versus the combination of neglect and abuse, and we tested whether mothers’ experiences with maltreatment in their own childhood moderated the association between their current maltreatment status and physiology. During a standardized cry paradigm, mothers listened to cry sounds of various pitches. Heart rate (HR), pre-ejection period (PEP), skin conductance levels (SCLs), and vagal tone (root mean square of successive differences [RMSSD]) were measured as indicators of underlying sympathetic and parasympathetic reactivity. The maltreating mothers showed lower SCL reactivity to the cry sounds than non-maltreating mothers. Furthermore, significant negative correlations between HR and PEP in the non-maltreating group differed from nonsignificant correlations in the maltreating group, which suggests a lack of sympathetic cardiac control in maltreating mothers. We found no differences between neglectful mothers and those who were additionally abusive. Together, our findings support the notion of sympathetic hypoarousal as a risk factor for child maltreatment, which may be indicative of disengagement in a caregiving context. Intervention programs might focus on improving maternal sensitivity to improve responsiveness to child signals.
Multiverse: efficiently supporting distributed high-level speculation

Algorithmic speculation or high-level speculation is a promising programming paradigm which allows programmers to speculatively branch an execution into multiple independent parallel sections and then choose the best (perhaps fastest) amongst them. The continuing execution after the speculatively branched section sees only the modifications made by the best one. This programming paradigm allows programmers to harness parallelism and can provide dramatic performance improvements. In this paper we present the Multiverse speculative programming model. Multiverse allows programmers to exploit parallelism through high-level speculation. It can effectively harness large amounts of parallelism by speculating across an entire cluster and is not bound by the parallelism available in a single machine. We present abstractions and a runtime which allow programmers to introduce large scale high-level speculative parallelism into applications with minimal effort. We introduce a novel on-demand address space sharing mechanism which provide speculations efficient transparent access to the original address space of the application (including the use of pointers) across machine boundaries. Multiverse provides single commit semantics across speculations while guaranteeing isolation between them. We also introduce novel mechanisms to deal with scalability bottlenecks when there are a large number of speculations. We demonstrate that for several benchmarks, Multiverse achieves impressive speedups and good scalability across entire clusters. We study the overheads of the runtime and demonstrate how our special scalability mechanisms are crucial in scaling cluster wide.
Turning Points and Transitions: Perceptions of the Life Course

This study uses American (Manchester, New Hampshire) and Japanese (Shizuoka) cohorts in 1910-1950 to explore the similarities and differences between "life-course transitions, " defined as the movements of individuals and families within socially constructed time-tables; and "life-course turning points," which represent individuals' subjective assessment of continuities and discontinuities over their lives. Considerable differences are found among cohorts in each society, but there are also similarities that cut across both societies. Whereas cultural differences in the timing of life transitions and the subjective construction of the life course are significant, the common experience of cohorts in response to shared historical events may transcend cultural differences.
Detailed analysis of a current-doubler rectifier for an LLC resonant converter with high output current

Current-doubler rectifiers are well-known in conjunction with double ended buck-derived isolated converters. One major purpose for its implementation is the reduction of power losses in the transformer secondary winding. The topic of this paper is an extension to this approach and presents a detailed analysis of a current-doubler rectifier used in an LLC resonant converter. The analysis uses the first harmonic approximation (FHA) approach, which tremendously simplifies the system model, leading to a linear circuit. The design constraints are worked out, such that the converter behavior remains unaltered by adding the current-doubler. By using this type of rectifier, the LLC efficiency can be improved over a traditional approach with a center tapped secondary winding. The secondary side power losses are reduced significantly and the drawback of an unequal coupling between the primary and either one of the two secondary windings is eliminated. Measurements on a prototype verify the analytical and simulation results.
Reduction in Pain Sensitivity from Pharmacological Elevation of Blood Pressure in Persons with Chronically Low Blood Pressure

Recent studies have revealed evidence for increased pain sensitivity in individuals with chronically low blood pressure. The present trial explored whether pain sensitivity can be reduced by pharmacological elevation of blood pressure. Effects of the sympathomimetic midodrine on threshold and tolerance to heat pain were examined in 52 hypotensive persons (mean blood pressure 96/61 mmHg) based on a randomized, placebo-controlled, double-blind design. Heat stimuli were applied to the forearm via a contact thermode. Confounding of drug effects on pain perception with changes in skin temperature, temperature sensitivity, and mood were statistically controlled for. Compared to placebo, higher pain threshold and tolerance, increased blood pressure, as well as reduced heart rate were observed under the sympathomimetic condition. Increases in systolic blood pressure between points of measurement correlated positively with increases in pain threshold and tolerance, and decreases in heart rate were associated with .
Protégé or Go-Between? The Role of the baltic states after 9/11 in eu–US Relations

Since 9/11, Washington has viewed the new Europe as a protégé of the United States, whose role is to repair the political bridge across the Atlantic. Whereas the lure of the United States has started to weaken in Central European countries, the Baltic states have remained the most trustful new Europeans from Washington's point of view. Nonetheless, the Balts have not felt comfortable with the new European label. They have seemingly begun to define themselves as something special and have aspired to a voice of their own. Instead of being merely protégés of the United States, the Balts are transforming themselves into intermediaries between Brussels and Washington.
Ability Conceptions in Physical Education: Some Measurement Considerations

The construct of ability conceptions plays a critical role in children's motivation and achievement behaviors in education, including physical education. Valid and reliable measures of this construct are essential to advance our knowledge of children's ability conceptions and related cognitive, affective, and behavioral outcomes. From a measurement point of view, this article discusses the construct of ability conceptions from two major theoretical perspectives in terms of differences and commonalities. It also offers insights to further improve the psychometric properties of ability conceptions measures.
Sequence differences in the internal transcribed spacer 1 and 5.8S ribosomal RNA among three Moniezia species isolated from ruminants in Japan

This study was designed to clarify the differences in the internal transcribed spacer (ITS) 1 and 5.8S nucleotide sequences of Moniezia expansa, M. benedeni and M. monardi isolated from ruminants in Japan and to determine their phylogenetic relationships. A 98% similarity in the 5.8S sequences was observed among the 3 Moniezia species, whereas many nucleotide indels and substitutions were observed in the ITS1 sequences among the three Moniezia species. These results suggest that the ITS1 region could serve as a potential marker for discriminating the 3 Moniezia species. In the phylogenetic tree based on the ITS1 sequences, M. monardi and M. benedeni showed genetically closer relationship to each other than to M. expansa.
Pharmacological and interventional treatments for neuropathic pain

Neuropathic pain originates from a lesion within the central or peripheral nervous system. The signs of neuropathic pain include heat hyperalgesia, mechanohyperalgesia, and mechanoand cold allodynia. Traditionally, neuropathic pain responds poorly to conventional analgesics. This chapter will provide recommendations for medical and interventional management of neuropathic pain conditions based on the best scientific evidence in the literature. Anticonvulsants (e.g., gabapentin and pregabalin), antidepressants (e.g., amitritpyline and duloxetine), and topical lidocaine have been the most consistent Correspondence/Reprint request: Dr. Paul J. Christo, Department of Anesthesiology and Critical Care Medicine, The Johns Hopkins University School of Medicine, 550 N. Broadway, Suite 301, Baltimore Maryland 21205, USA. E-mail: pchristo@jhmi.edu Bryan S. Williams & Paul J. Christo 296 in demonstrating effectiveness through randomized control trials. Certain circumstances may require the use of opioids as a first-line treatment for specific neuropathic pain states. Interventional strategies such as neural blockade, implantable drug delivery systems, and spinal cord stimulation can be beneficial for alleviating painful neuropathic conditions that respond less favorably to medical therapies, or as a method of augmenting current medical therapies. A rational approach for the treatment of specific neuropathic conditions is presented in the form of tables that consider first line, second line, and other therapies.
Decentralized Orchestration of CompositeWeb Services

Traditional, centralized orchestration of composite Web services often leads to inefficient routing of messages. To solve this problem, we present a novel scheme to execute composite Web services in a fully decentralized way. We introduce service invocation triggers, a lightweight infrastructure that routes messages directly from the producing service to the consuming one, enabling fully decentralized orchestration. An evaluation confirms that decentralized orchestration can significantly reduce the network traffic when compared with centralized orchestration
Genotype and allele frequency of CYP2C19*17 in a healthy Iranian population

Background: Cytochrome P450 2C19 (CYP2C19) is important in metabolism of wide range of drugs. CYP2C19*17 is a novel variant allele which increases gene transcription and therefore results in ultra-rapid metabolizer phenotype (URM). Distribution of this variant allele has not been well studied worldwide. The aim of present study was to investigate allele and genotype frequencies of CYP2C19*17 in a healthy Iranian population and compare them with other ethnic groups. Methods: One hundred eighty healthy unrelated Iranian volunteer took part in this study and were genotyped for CYP2C19 *2, *3, *17 (-3402) by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and CYP2C19*17 (-806) by a nested-PCR assays. The distribution of CYP2C19*17 polymorphism in Iranian population was then compared with other ethnic groups. Results: The CYP2C19*17 allele frequency was 21.6% in Iranian population. Among studied subjects 5.5% were homozygous for CYP2C19*17 and phenotyped as ultra-rapid metabolizers; 28.8% were genotyped as CYP2C19*1*17 (extensive metabolizers) and 3.3% as CYP2C19*2*17 (intermediate metabolizers). Conclusion: The CYP2C19*17 genetic distribution in Iranian population is similar to Middle East or European countries. The high frequency of CYP2C19*17 in Iranian population highlights the importance of this new variant allele in metabolism of CYP2C19 substrates. Thus, future association studies are required to reveal clinical consequence of this genetic polymorphism in carrier individuals.
