Enhanced mobile digital video broadcasting with distributed space-time coding

This paper investigates the distributed space-time (ST) coding proposals for the future Digital Video Broadcasting-Next Generation Handheld (DVB-NGH) standard. We first theoretically show that the distributed MIMO scheme is the best broadcasting scenario in terms of channel capacity. Consequently we evaluate the performance of several ST coding proposals for DVB-NGH with practical system specifications and channel conditions. Simulation results demonstrate that the 3D code is the best ST coding solution for broadcasting in the distributed MIMO scenario.
"Alien Health": A Nutrition Instruction Exergame Using the Kinect Sensor.

Objective: A feasibility study was run on an embodied exergame designed to teach 4th-12th grade students about nutrition and several U.S. Department of Agriculture (USDA) MyPlate guidelines. The study assessed efficacy on a new version of a game that was first implemented on an immersive platform and published in this journal in 2013. The earlier "Alien Health" game was redesigned for use with the Microsoft® (Redmond, WA) Kinect® sensor. Players learned about the amount of nutrients and optimizers in common food items and practiced making food choices while engaging in short cardio exercises. Subjects and Methods: Twenty 6th and 7th graders were randomly assigned to either the "Alien Health" game or a treated control condition. All engaged in "front of the classroom" performative activities. The "Alien Health" experimental group experienced the full game narrative of feeding the Alien and automated feedback on the quality of performed exercises. The control group experienced the same performative food choices at the interactive whiteboard but did no exercises. Two-week follow-up data were collected. Results: Both groups displayed statistically significant learning gains on the immediate nutrition knowledge posttest. The effect sizes from pretest to 2-week follow-up were 0.83 for the control group and 1.14 for the experimental group. Of interest is the crossover interaction from posttest to follow-up that approached significance (F19=3.96, P<0.058). Here, the experimental group outperformed the control group for knowledge retention. Conclusions: Results suggest acceptability, feasibility, and limited efficacy in a Kinect-based game to instruct in nutrition and the USDA MyPlate icon. The follow-up test revealed that nutrition knowledge continued to increase for the experimental group that performed short cardio exercises, suggesting that short exercises and perhaps a game narrative may have helped to consolidate content memory.
Clients’ Willingness to Incorporate Religion or Spirituality in Counseling

A total of 84 individuals with addiction issues (e.g., drugs, sex, weight, food, and codependency) were asked about their willingness to incorporate religion or spirituality in their counseling. These respondents expressed willingness to deal with religion or spirituality in counseling if the counselor was knowledgeable about their religion or spirituality. Degree of willingness was significantly related to clients’ religious background and age.
The technologisation of childhood? Young children and technology in the home

We describe an 18-month empirical investigation of three- and four-year-old children's uses of technology at home, based on a survey of 346 families and 24 case studies. The findings are reported in the context of social commentators' anxieties about the ways in which childhood is being transformed by technology. Although we report evidence of some parental disquiet about the role of technology in children's lives, we illustrate some of the complexities in families' attitudes to, and uses of, technology and conclude that it is not perceived by parents to be the threat to modern childhood that is claimed.
Early Structural Valve Deterioration of Mitroflow Aortic Bioprosthesis: Mode, Incidence, and Impact on Outcome in a Large Cohort of Patients

Background— Structural valve deterioration (SVD) is a major flaw of bioprostheses. Early SVD has been suspected in the last models of Mitroflow bioprosthesis. We sought to assess the incidence, mode, and impact of SVD on outcome in a large series of Mitroflow aortic valve replacement. Methods and Results— Six hundred seventeen consecutive patients (aged 76.1±6.3 years) underwent aortic valve replacement with a Mitroflow prosthesis (models 12A/LX) between 2002 and 2007. By echocardiography, 39 patients developed early SVD (1.66% per patient-year), with stenosis as the main mode (n=36). Mean delay to SVD was only 3.8±1.4 years, and 5-year SVD-free survival was 91.6% (95% confidence interval [CI], 88.7–94.7) for the whole cohort and 79.8% (95% CI, 71.2–89.4) and 94.0% (95% CI, 90.3–97.8) for 19- and 21-mm sizes, respectively. Among the 39 patients with SVD, 13 patients (33%) had an accelerated SVD once the mean gradient exceeded 30 mm Hg. Valve-related death was 46.2% in this SVD subgroup. Five-year overall survival was 69.6% (95% CI, 65.7–73.9). In multivariable analysis, SVD was the strongest correlate of overall mortality (hazard ratio=7.7; 95% CI, 4.4–13.6). Conclusions— Early SVD is frequent in Mitroflow bioprosthesis (models 12A/LX), especially for small sizes (19 and 21 mm), and reduces overall survival. An unpredictable accelerated pattern of SVD constitutes a life-threatening condition. In view of the large number of Mitroflow valves implanted worldwide, one can expect an epidemic of SVD and valve-related deaths, which represents a major public health issue, especially in the elderly. Hence, a close follow-up with yearly echocardiography after Mitroflow implantation is advisable. An urgent reoperation should be discussed in patients with severe SVD even though they are still asymptomatic.
Face consciousness and risk aversion: Do they affect consumer decision‐making?

This article explores the effects of two cultural dimensions, face consciousness and risk aversion, on consumers' decision-making styles. Data from China and the United States show that consumers in the United States differ from their counterparts in China in decision-making styles. Face consciousness and risk aversion appear to contribute to such divergence. Implications for future research are discussed. © 2003 Wiley Periodicals, Inc.
Unsupervised Detection of Annotation Inconsistencies Using Apriori Algorithm

We present a new method for automated discovery of inconsistencies in a complex manually annotated corpora. The proposed technique is based on Apriori algorithm for mining association rules from datasets. By setting appropriate parameters to the algorithm, we were able to automatically infer highly reliable rules of annotation and subsequently we searched for records for which the inferred rules were violated. We show that the violations found by this simple technique are often caused by an annotation error. We present an evaluation of this technique on a hand-annotated corpus PDT 2.0, present the error analysis and show that in the first 100 detected nodes 20 of them contained an annotation error.
The Leadership Teachers Want from Principals: Transformational

The purpose of this study, which was part of a larger study, was to examine teacher perceptions of transformational leadership qualities among principals. From a randomly generated sample of 135 public schools in the province of Alberta, Canada, 77 schools agreed to participate in a study on leadership attributes of principals. Ten randomly selected teachers from each participating school were asked to complete the Multifactor Leadership Questionnaire (MLQ) (Bass & Avolio, 1995, 1997, 2000a) for their respective principals. The MLQ was a quantitative instrument in which teachers rated principals. Based on teacher responses, principals were stratified into categories according to whether they possessed high or low levels of transformational leadership qualities. Using the MLQ to rank principals allowed for clear selection criteria to group them. Once the principals were stratified, 10 teachers were then selected for in-depth interviews. Five of the teachers worked with principals who were characterized as highly transformational
The density of protein precipitates and its effect on centrifugal sedimentation

Isoelectric soya‐protein precipitate densities were measured for mean particle sizes ranging from 3.4–65 μm by gradient centrifugation, centrifugation in water‐immiscible solvents, tracerdilution, gravity sedimentation of isolated particles. Coulter counter volume determination, and a comparison of Coulter counter and centrifugal sedimentation size distributions. The immiscible system and tracer dilution methods were both found to be unreliable due to experimental uncertainties. The Coulter counter volume measurement indicated the existence of a density‐size relationship with the aggregate density decreasing as the size increased. Comparison with sedimentation measurements showed that the Coulter counter measures 80% of the total aggregate volume for 6‐μm particles. The relation between aggregate density (ρa, kg m −3) and size (d, μm) was measured for isoelectric soya protein and casein precipitated by ammonium sulfate, using a comparison of the Coulter counter size distribution and centrifugal sedimentation. The functions were described for soya by \documentclass{article}\pagestyle{empty}\begin{document}$$ \rho _a - 1004 = 246d^{ - 0.408} $$\end{document} and for casein by \documentclass{article}\pagestyle{empty}\begin{document}$$ \rho _a - 1136 = 31d^{ - 0.441} $$\end{document} The gradient centrifugation method measured the buoyant density of hydrated protein precipitate which was independent of size, and is consistent with an aggregate structure consisting of primary particles. However, the aggregate structure was not described for all sizes by the theoretical cubic packing of hard‐sphere primary particles, nor by the successive random addition of primary particles. The density‐size functions indicated up to a fivefold difference in Stokes settling velocities compared to those calculated assuming a constant density difference.

Designing Discussions as Group Inquiry

None of us likes to see a class dis cussion go flat. Silence falls. Dis comfort clouds the room. Fear ing the awkwardness of silence, we resort to other teaching techniques, predomi nantly the lecture method (Clarke 1987). Happy to escape oppressive silence, our students bend quietly to their note books. In turning to our own knowledge to fill the void, we deprive our students of a chance to practice inquiry within our disciplines. By planning discussions as models of inquiry, we can engage stu dents in examinations of content that also emphasize the kind of thinking we espouse (Schwartz 1980). When concept development, creative thinking, critical thinking or problem solving are the goals of teaching, re search favors discussion over lecture/ demonstration techniques (McKeachie 1986, Bernstein 1976). Students respect an enthusiastic and accurate explanation of content, but their personal involve ment may be the key to higher order learning (Astin 1984). College instruc tors can design discussion classes so that students use the concepts and processes of the discipline to evaluate facts and move toward reliable conclusions.
A Climate Change Vulnerability Assessment of California's At-Risk Birds

Conservationists must develop new strategies and adapt existing tools to address the consequences of anthropogenic climate change. To support statewide climate change adaptation, we developed a framework for assessing climate change vulnerability of California's at-risk birds and integrating it into the existing California Bird Species of Special Concern list. We defined climate vulnerability as the amount of evidence that climate change will negatively impact a population. We quantified climate vulnerability by scoring sensitivity (intrinsic characteristics of an organism that make it vulnerable) and exposure (the magnitude of climate change expected) for each taxon. Using the combined sensitivity and exposure scores as an index, we ranked 358 avian taxa, and classified 128 as vulnerable to climate change. Birds associated with wetlands had the largest representation on the list relative to other habitat groups. Of the 29 state or federally listed taxa, 21 were also classified as climate vulnerable, further raising their conservation concern. Integrating climate vulnerability and California's Bird Species of Special Concern list resulted in the addition of five taxa and an increase in priority rank for ten. Our process illustrates a simple, immediate action that can be taken to inform climate change adaptation strategies for wildlife.
Saturation of Enzyme Kinetics in Circadian Clock Models

From the mathematical study of simple models for circadian rhythm, the authors identified a clear effect of saturation in the enzyme kinetics on the promotion or suppression of a sustained oscillation. In the models, a clock gene (pergene) is transcribed to produce mRNAs, which are translated to produce proteins in the cytosol, which are then transported to the nucleus and suppress the transcription of the gene. The negative feedback loop with a long time delay creates sustained oscillation. All the enzymatic reactions (e.g., degradation, translation, and modification) are assumed to be of Michaelis-Menten type. The reaction rate increases with the amount of substrate but saturates when it is very large. The authors prove mathematically that the saturation in any of the reactions included in the feedback loop (in-loop reaction steps) suppresses the oscillation, whereas the saturation of both degradation steps and the back transport of the protein to cytosol (branch reaction steps) makes the oscillation more likely to occur. In the experimental measurements of enzyme kinetics and in published circadian clock simulators, in-loop reaction steps have a small saturation index whereas branch reaction steps have a large saturation index.
Family caregivers of people with dementia

Family caregivers of people with dementia, often called the invisible second patients, are critical to the quality of life of the care recipients. The effects of being a family caregiver, though sometimes positive, are generally negative, with high rates of burden and psychological morbidity as well as social isolation, physical ill-health, and financial hardship. Caregivers vulnerable to adverse effects can be identified, as can factors which ameliorate or exacerbate burden and strain. Psychosocial interventions have been demonstrated to reduce caregiver burden and depression and delay nursing home admission. Comprehensive management of the patient with dementia includes building a partnership between health professionals and family caregivers, referral to Alzheimer's Associations, and psychosocial interventions where indicated.
Penetration of ofloxacin and ciprofloxacin into the aqueous humor of eyes with functioning filtering blebs: a randomized trial.

OBJECTIVE To determine concentrations of ofloxacin and ciprofloxacin hydrochloride in aqueous humor after topical or combined topical and oral administration in eyes with filtering blebs. DESIGN A prospective, investigator-masked, randomized, controlled comparative study involving 36 eyes of 34 patients with functioning filtering blebs who were to undergo cataract surgery. Treatment groups received either topical ofloxacin or topical ciprofloxacin (instillation of 0.3% ophthalmic solution every 30 minutes for 4 hours before surgery), or a combined topical plus oral regimen (ciprofloxacin hydrochloride, four 100-mg tablets, or ofloxacin, one 400-mg tablet, administered 24-26, 12-14, and 2 hours preceding surgery). The main outcome measure was antibiotic concentration measured by chromatographic separation and mass spectrometry of aqueous samples obtained during surgery. RESULTS Topical antibiotic treatment yielded mean concentrations of ofloxacin, 0.75 microg/mL, and ciprofloxacin, 0.21 microg/mL, in aqueous. With combined topical and oral therapy, significantly more ofloxacin was measured than ciprofloxacin (3.84 microg/mL vs 0.35 microg/mL [P<.001]). The combination regimen produced significantly greater ofloxacin levels than did topical therapy alone (P =.007). CONCLUSIONS Ofloxacin penetrates better than ciprofloxacin into the aqueous of eyes with filtering blebs, particularly after combined topical and oral administration, by which ofloxacin reaches more than a 10-fold greater concentration than does ciprofloxacin. Combined topical and oral therapy with ofloxacin may be beneficial in the treatment of bleb-associated infections.
Towards Self-Composing, Prioritized and Consequential Services

Service-oriented architecture (SOA) is emerging as a very significant approach to enterprise computing. SOA is seen as a major impetus to providing agility and consumer centric approach to enterprise computing. Integral to the service oriented architecture approach is the concept of a "service", a service provider and a service consumer. The services in SOA context are realized by software or software in conjunction with business processes. It is believed that significant value can be derived by designing intelligent services. Benefit includes overall performance and flexibility. Intelligent services are those that are able to compose themselves based on certain rules and configurations, able to come into existence only when required and only for a required duration, and are prioritized. It is found out that these attributes make the services extremely useful, and enhance the overall performance of the SOA deployment
Forty years on … and accelerating

This journal began its life on 1 January 1974 as the British Journal of In-service Education. There were three issues planned for the first year and the Editors of that first issue heralded the new journal by identifying a need for an academic and professional publication focusing on the continuing education of serving teachers. Following years of an ad hoc approach to in-service education, new ideas and policies were emerging that were to transform the ways in which local and national governments, school leaders and teachers themselves engaged in the policy and practice of what was then known as INSET. The Editorial for issue 1 stated:
Sensor-Network-Aided Cognitive Radio: On the Optimal Receiver for Estimate-and-Forward Protocols Applied to the Relay Channel

Cognitive radio describes a promising concept for improving the utilization of radio spectrum. It allows secondary users to access licensed radio spectrum in an opportunistic fashion, given that the quality of service for primary users is maintained. In this scenario, the detection of unused radio spectrum is the main obstacle: it requires the recognition of low- power signals in a noisy environment. Therefore, we consider the case where cognitive users are supported by a wireless sensor network (WSN) providing beliefs on the event that the primary user is active. The beliefs provided by the WSN nodes are then combined by the cognitive radio in order to make a final decision. Due to limitations in complexity, power, and bandwidth, the WSN nodes apply the estimate-and-forward protocol to communicate their beliefs and to relay the beliefs of adjacent nodes. For the case where the WSN is subject to noisy communication links, we derive and analyze the optimal receiver which provides the cognitive radio with log-likelihood ratios for the estimated and forwarded hypotheses. The performance of the optimal receiver is compared to the performance of sub-optimal receivers.

Taxonomic updates in Dolichandra Cham. (Bignonieae, Bignoniaceae)

Abstract Dolichandra is a genus of lianas found in dry and wet Neotropical forests. The genus currently includes eight species and is well characterized by molecular and morphological synapomorphies. Here, Macfadyena hispida (DC.) Seemann is removed from synonomy with Dolichandra uncata (Andrews) L.G. Lohmann based on the presence of the hispid indument, vinaceus ovary, long fruits, and winged seeds. The combination Dolichandra hispida (DC.) L.H. Fonseca & L.G. Lohmann, comb. nov. is proposed, increasing the number of accepted species of Dolichandra to nine. A taxonomic key for all species of Dolichandra is presented.
Test Preparation Activities and Employment Test Performance

This study examined the relation among motivational factors, test preparation activities (metacognition and learning strategies), and employment test scores using data from 493 actual job applicants to a state law enforcement agency. Results showed that motivational factors are related to metacognition and the learning strategies in which applicants engage. Use of these activities was in turn associated with higher test performance.
In Search of (Better) Sexual Pleasure: Female Genital ‘Cosmetic’ Surgery

Female genital cosmetic surgery (FGCS) procedures are new, but increasing in popularity. In this article, I examine the role of female sexual pleasure in media (31 magazine items) and surgeon (15 interviews) accounts. FGCS was framed as enhancing female sexual pleasure, or specifically orgasm. I argue that the focus on female sexual pleasure functions to legitimate, and promote, FGCS. Further, it reaffirms normative heterosexuality, and promotes a generic model of bodies and sex. Moreover, in the context of consumer culture, media accounts have the possibility of creating problems, and their solutions, simultaneously.
Experimental Evidence for Preschoolers' Mastery of "Topic"

This study investigates the acquisition of the discourse/pragmatic notion of topic, based on an experimental task eliciting topic vs. focus subjects. In spoken French, these are obligatorily realized as dislocated vs. nondislocated noun phrases. The results provide overwhelming evidence for the early mastery of topic, even by the youngest children (2;6). The only difficulty was in the evaluation of fine-grained salience distinctions, leading to the underuse of full noun phrases in ambiguous contexts. A theory of mind test revealed that the ability to assess their listener's knowledge state is not sufficient to explain this underuse. Instead, children's overreliance on the situational context as a source of complementary information to disambiguate their utterances is argued to have a major impact on how explicit they are.
